Technical Field
[0001] The utility model relates to the field of chip testing, in particular to a film packing and releasing mechanism for a chip receiving tray. Background Art
[0002] Chips have become closely related to people's lives and play an important role. Cars need chips, mobile phones need chips, and electrical appliances need chips. As long as a product is associated with the word "technology", it needs to use chips. Chips are the brains and hearts of all electronic products and devices.
[0003] Among them, after the chips are produced, they are not immediately put into use. Because when the chips are produced, there may be defective products due to various reasons. Therefore, all chips need to be tested to check whether their performance is qualified. When testing the chips, the chips are placed on the chip testing equipment for rapid testing. When using a rotary testing equipment for testing, the chips are fed through a vibrating feeding tray, and the testing equipment grabs the chips to the testing position for testing. After the testing is completed, the chips are individually wrapped by a carrier tape, and then the carrier tape with the chips is wound up by a receiving tray.
[0004] In order to prevent problems such as the internal chips falling, being lost, or damaged due to the damage of the carrier tape during the transportation of the receiving tray, generally, the receiving tray wound with the carrier tape is externally wrapped with a protective film for protection. When packing, the film roll is placed on the rack and rotated, and the protective film is pulled out by a traction mechanism or manually. The operator can wind the protective film around the outside of the receiving tray. In the prior art, during the unwinding process of the film roll, the film roll may become loose. Especially during the pulling out process of the film roll, the film roll may rotate along with the pulling, resulting in the unwinding of the protective film. However, when the traction of the film roll stops, the film roll will still rotate due to inertia, causing the wound film roll to become loose.
[0005] As a result, when the film roll is pulled out for packing later, due to the looseness of the film roll, the packing efficiency is affected, and the labor intensity of the operator is increased. Summary of the Invention

[0031] The utility model is further described below in conjunction with the accompanying drawings and embodiments:
[0032] Example 1: See Figures 1-3As shown in the figure, a film packaging and releasing mechanism for a chip receiving tray includes a frame 1, a support assembly 2 disposed on the frame 1, and a film pressing mechanism. There are two groups of the support assemblies 2, and a material releasing spacing 3 is formed between the two groups of the support assemblies 2. The film pressing mechanism is disposed directly above the material releasing spacing 3.
[0033] The film pressing mechanism includes a pressing wheel 4, and the pressing wheel 4 is connected to the frame 1 through a connecting plate 5.
[0034] The rear end of the connecting plate 5 is rotatably connected to the frame 1. The pressing wheel 4 is rotatably connected to the left side of the front end of the connecting plate 5. The bottom outer surface of the pressing wheel 4 is disposed below the bottom surface of the front end of the connecting plate 5.
[0035] A counterweight portion is further installed on the right side of the front end of the connecting plate 5. The counterweight portion and the pressing wheel 4 are respectively disposed on both sides of the connecting plate 5.
[0036] In this embodiment, the film roll 6 is wound on the film unwinding shaft 7. When in use, the film roll 6 is between the support components on both sides, and the two ends of the film unwinding shaft are placed on the support components. The film unwinding shaft is supported by the support components on both sides, and the pressing wheel of the film pressing mechanism is directly pressed on the top outer surface of the film roll. In this way, when the end of the film roll is pulled out for unwinding, the film roll will rotate on the support components on both sides through the film unwinding shaft. In order to prevent the film roll from loosening when it is on the film unwinding shaft during the unwinding process, and to prevent the film roll from falling from the support components after the weight of the film roll is reduced during the unwinding process, the film pressing mechanism is set so that the pressing wheel can always be against the film roll, thereby preventing the film roll from loosening. Since the pressure wheel rotates on the connecting plate, the connecting plate and the frame are connected in rotation, wherein a connecting rod 8 is arranged above the rear side of the unwinding spacing, the connecting rod is arranged parallel to the axis of the film unwinding shaft, the rear end of the connecting plate is connected in rotation, or the rear end of the connecting rod is connected in rotation with the frame through the connecting rod, due to the gravity of the pressure wheel, the pressure wheel is always against the outer surface of the top plate of the film roll, especially during the unwinding process, the diameter of the film roll gradually decreases, due to the weight of the pressure wheel and the connecting plate, the front end of the connecting plate will also move down with the reduction of the diameter of the film roll, so that the pressure wheel is always against the outer surface of the top of the film roll. Furthermore, since the weight of the pressure wheel is generally light, after unwinding to a certain extent, the diameter of the film roll is relatively small, and the overall weight of the film roll and the support shaft is relatively light, when the film roll is subjected to a large traction force or the instantaneous traction speed is fast, the support shaft may move up and break away from the support assembly and fall (the weight of the pressure wheel is relatively small and cannot press the film roll and the support shaft), there is a safety hazard. Or the film roll itself is a material that is easy to loosen, and the pressure wheel cannot press the film roll, causing the film roll to loosen. Therefore, in this embodiment, a counterweight is also provided on the connecting plate to counterweight the front end of the connecting plate, and the counterweight is provided on the other side of the pressure wheel, so that the pressure of the front end of the connecting plate toward the bottom can be increased, that is, the pressure of the pressure wheel on the film roll can be increased, and the surface of the film roll can be tightly pressed by the pressure wheel to prevent the film roll from loosening and falling from the supporting assembly. Among them, multiple transmission shafts can also be provided on the frame for transmission and guidance during the film unwinding process.
[0037] At the same time, in this embodiment, the pressure of the pressure wheel on the film roll is increased by setting the counterweight part, so that when the operator manually pulls out the film roll, a certain force is required to make the film roll have a certain hand feeling when being pulled out, that is, the pressure wheel also plays a certain damping role, and after releasing the pulling of the film roll, the rotational inertia of the film roll is limited by the pressure wheel, and it will only rotate a little bit, thereby preventing the film roll from being released enough. During the rotation of the film roll, the pressure wheel will also rotate.
[0038] See also Figure 1 , 2As shown, the counterweight part includes a counterweight frame 9 and counterweight blocks 10 mounted on the counterweight frame 9. The counterweight frame 9 is connected to the connecting plate 5. A vertical rod 11 is provided at the top of the counterweight frame 9. The counterweight blocks 10 are detachably sleeved on the vertical rod 11.
[0039] There is at least one counterweight block 10, and multiple counterweight blocks 10 are stacked from bottom to top. A limit nut 12 is screwed on the vertical rod 11, and the bottom of the limit nut 12 abuts against the top surface of the topmost counterweight block 10.
[0040] In this embodiment, the bottom of the vertical rod is screwed to the counterweight frame, so that the vertical rod with a corresponding length can be replaced according to the weight or quantity of the counterweight blocks to be actually installed. A hole is provided in the middle of the counterweight block. When installing the counterweight block, unscrew the limit nut, and the counterweight block is directly sleeved on the vertical rod through the middle hole. If multiple counterweight blocks need to be installed, the counterweight blocks are sequentially sleeved on the outside of the vertical rod, and then the limit nut is screwed to the vertical rod to limit the counterweight blocks on the vertical rod (the bottom of the bottommost counterweight block abuts against the top surface of the counterweight frame). If the number of counterweight blocks is a little more, making the heights of multiple counterweight blocks different, just replace the vertical rod with a corresponding length, which can prevent the vertical rod from protruding too much above the counterweight block.
[0041] In this embodiment, the connecting plate can adjust the horizontal position on the connecting rod, so that the pressing position of the pressing wheel on the film roll can be adjusted.
[0042] See Figures 1-3 As shown, vertical plates 13 are respectively provided on both sides of the front end of the frame 1, and each supporting component 2 is respectively mounted on a vertical plate 13.
[0043] The supporting component 2 includes a bracket 14 and two supporting bearings 15. The bracket 14 is arranged inside the corresponding vertical plate 13, and the outer end of the bracket 14 is connected to the vertical plate 13;
[0044] The two supporting bearings 15 are respectively rotatably connected to the inner end of the bracket 14, and the two supporting bearings 15 are arranged at intervals in the front and rear. A supporting distance is formed between the two supporting bearings 15.
[0045] In this embodiment, in order to facilitate the placement and removal of the film roll, the end of the film unwinding shaft of the film roll is directly placed on the corresponding support assembly, the film roll is wound on the middle outer surface of the film unwinding shaft, and the two ends of the film unwinding shaft are outside the two ends of the film roll (or the film roll is wound on a hollow paper tube or the outside of the support tube. Taking the paper tube as an example, the end of the paper tube is flush with the end of the film roll, which is convenient for the transportation of the film roll. When the film roll needs to be unwound, the film unwinding shaft is inserted into the interior of the paper tube, and its two ends are outside the two ends of the paper tube). When the film roll is installed on the frame, the end of the film unwinding shaft is directly placed in the support spacing of the corresponding support assembly, and the two sides of the bottom of the film unwinding shaft are respectively against a support bearing. In the process of pulling out the film roll for unwinding, the film unwinding shaft can be rotatably supported by the support bearing. The weight of the film roll and the pressure of the pressure wheel on the film roll can prevent the film unwinding shaft from leaving the support spacing, thereby ensuring stability and safety during the film unwinding process.
[0046] See also Figure 3 As shown, the outer end of the bracket 14 is slidably connected to the vertical plate 13 via at least two transverse guide rods 16, and the outer end of the transverse guide rod 16 is arranged on the outer side of the vertical plate 13;
[0047] A fixing plate 17 is disposed on the outer side of the vertical plate 13, and the outer end of the transverse guide rod 16 is connected to the fixing plate 17;
[0048] An adjusting screw 18 is also rotatably mounted on the fixing plate 17. The adjusting screw 18 is arranged parallel to the transverse guide rod 16. The middle portion of the adjusting screw 18 is screwed to the vertical plate 13. The inner end of the adjusting screw 18 is rotatably connected to the bracket 14.
[0049] When the adjusting screw 18 rotates, the bracket 14 is driven to move, and the bracket 14 is arranged close to or away from the vertical plate 13 .
[0050] In this embodiment, since the sizes of different trays are different, the widths of the film rolls required are also different. To prevent waste of the film rolls, it is only necessary to wrap the trays with film rolls of corresponding sizes. The distance between the two vertical plates in the equipment is fixed. If a film feeding shaft with a longer length is used to support the film roll, during the process of moving the film roll to the feeding position of the rack and loading the film roll onto the rack, the material moving equipment and feeding equipment used will be larger, occupying more material moving space, and it is also inconvenient for material moving and feeding, especially it is more inconvenient to adjust the position of the film roll in the middle of the film feeding shaft, and the difficulty of centering adjustment of the film roll is higher. At the same time, when the length of the film feeding shaft is too long, the weight of the film roll is mainly supported by the middle part of the film feeding shaft, and the middle part of the film feeding shaft is subjected to greater force for a long time, that is, the force on the film feeding shaft is uneven for a long time, which easily causes the film feeding shaft to deform and affect the service life of the film feeding shaft. Therefore, in this embodiment, the bracket is movably connected to the corresponding side vertical plate through the transverse guide rod, and then by setting the adjusting screw, rotating the adjusting screw can drive the bracket to move relative to the corresponding vertical plate through the transverse guide rod, and the distance between the two brackets can be adjusted. In this way, a film roll with a corresponding width can use a film feeding shaft with a corresponding length, which can solve the above problems. If the width of the film roll is small, a film feeding shaft that is a little longer than the width of the film roll is used, then the distance between the two brackets is adjusted, and then the two ends of the film feeding shaft are respectively placed within the support spacing of the two brackets, and the corresponding support bearings are used to rotatably support the ends of the film feeding shaft. Similarly, when the width of the film roll is wider, the distance between the two brackets is adjusted so that the two brackets are far away from each other to adapt to the film feeding shaft and film roll of the corresponding width.
[0051] At the same time, in this embodiment, a fixing plate is also provided to connect the outer end of the transverse guide rod and to rotatably connect with the adjusting screw, so as to limit the transverse guide rod and the adjusting screw (the outer end of the adjusting screw will not axially move relative to the fixing plate), prevent the transverse guide rod and the adjusting screw outside the vertical rod from deforming, ensure that the transverse guide rod can smoothly slide connect with the vertical plate, and the adjusting screw can stably screw connect with the vertical plate, prevent the problem of movement jamming caused by the deformation of the transverse guide rod and the adjusting screw, and ensure the stability and smoothness of the movement of the bracket. And the combination of the fixing plate and the bracket can prevent the transverse guide rod from detaching from the support plate.
[0052] See Figure 3 As shown, a gripping head 19 is provided at the outer end of the adjusting screw 18, and the gripping head 19 is arranged outside the fixing plate 17. The setting of the gripping head facilitates the operator to drive the adjusting screw to rotate to adjust the distance between the bracket and the vertical plate, without the need to use tools to drive the adjusting screw to rotate.
[0053] See Figure 3As shown, a clearance notch 20 is provided at the top of the bracket 14, and the clearance notch 20 is arranged opposite to the support spacing. The setting of the clearance notch can make way for the end of the film placing shaft to prevent the film placing shaft from contacting the bracket during installation, which causes the film placing shaft to be unable to be smoothly placed on the support bearing. The end of the film placing shaft is placed in the clearance notch, so that the clearance notch can also limit the film placing shaft, preventing the film placing shaft from moving forward and backward and separating from the support bearing and falling.
[0054] Embodiment 2: A packaging and film placing mechanism for a chip receiving tray, the structure of which is basically the same as that of embodiment 1, except that: a connecting shaft is provided on the front end side wall of the connecting plate, the connecting shaft is arranged perpendicular to the connecting plate, and the pressure wheel is rotatably sleeved on the connecting shaft; limiting parts are respectively provided at both ends of the connecting shaft, and the pressure wheel is arranged between the limiting parts on both sides. The limiting part can be a nut or a clamp (which can limit the axial movement of the pressure wheel), and the pressure wheel is directly rotatably sleeved on the connecting shaft. The distance between the two limiting parts will be slightly larger than the length of the pressure wheel, thereby limiting the axial movement of the pressure wheel on the connecting shaft, and the connecting shaft is used for the installation of the pressure wheel. At the same time, according to the width of the film roll, different lengths of pressure wheels can be selected to be pressed on the film roll. If the film roll is wider, a longer pressure wheel can be selected, so that the pressure wheel can be pressed on the film roll for a longer length.
