Description

Technical Field

[0001] The utility model relates to the field of chip testing and packaging, in particular to an unwinding support mechanism. Background Art

[0002] Chips have become closely related to people's lives and play an important role. Automobiles need chips, mobile phones need chips, and electrical appliances need chips. Chips are the brains and hearts of all electronic products and devices.

[0003] Among them, after chips are produced, they are not immediately put into use. Because there will be defective products for various reasons during chip production, all chips need to be tested to check whether their performance is qualified. When testing chips, the chips are placed on a chip testing device for rapid testing. When using a rotary testing device for testing, the chips are fed through a vibrating feeding tray, and the testing device 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 take-up reel.

[0004] In order to prevent problems such as the internal chips falling, being lost, or damaged due to damage to the carrier tape during the transportation of the take-up reel, generally, a protective film is wrapped around the outside of the take-up reel with the carrier tape wound up for protecting the take-up reel. During packaging, the film roll is placed on the rack and rotated, and the protective film is pulled out by a traction mechanism or manually, and then the operator winds the protective film around the outside of the take-up reel.

[0005] Since the sizes of different reels are different, different widths of film rolls are required. To prevent waste of the film roll, a film roll of the corresponding size is used to wrap the reel. Generally, the support position for supporting the film roll in the equipment is fixed. If a longer film unwinding shaft is used to support the film roll, during the process of moving the film roll to the loading position of the equipment and loading the film roll onto the equipment, the material moving equipment and loading equipment used will be larger, more space will be occupied for material movement, and it is inconvenient for material movement and film unwinding, especially it is more inconvenient to adjust the film roll to the middle position of the film unwinding shaft, and the difficulty of centering the film roll is higher. At the same time, when the length of the film unwinding shaft is too long, the weight of the film roll is mainly supported by the middle part of the film unwinding shaft, and the middle part of the film unwinding shaft is subjected to greater force for a long time, that is, the force on the film unwinding shaft is uneven for a long time, which easily causes the film unwinding shaft to deform and affect the service life of the film unwinding shaft. Summary of the Invention

[0006] The purpose of the utility model is to provide an unwinding support mechanism. By using this structure, it can be applicable to film rolls of different widths, improve the applicable range, and at the same time improve the convenience of loading and extend the service life of the film unwinding shaft.

[0007] To achieve the above object, the technical solution adopted by the present utility model is as follows: A unwind support mechanism includes a frame, two vertical plates oppositely arranged on the frame, and support components respectively arranged inside one corresponding vertical plate, and the two support components on both sides are oppositely arranged;

[0008] The support component includes a bracket and two support bearings. The two support bearings are respectively rotatably connected to the inner end of the bracket, and the two support bearings are arranged at intervals front and back. A support spacing is formed between the two support bearings;

[0009] The outer end of the bracket is slidably connected to the vertical plate through at least two transverse guide rods, and the outer ends of the transverse guide rods are arranged outside the vertical plate;

[0010] A regulating screw is also screwed on the vertical plate. The regulating screw is arranged parallel to the transverse guide rod, and the inner end of the regulating screw is rotatably connected to the bracket.

[0011] In the above technical solution, when the regulating screw rotates, it drives the bracket to move and makes the bracket approach or move away from the vertical plate.

[0012] In the above technical solution, a fixing plate is further arranged outside each vertical plate. The outer end of the transverse guide rod is fixedly connected to the fixing plate. The outer end of the regulating screw passes through the fixing plate and is arranged outside the fixing plate, and the regulating screw is rotatably connected to the fixing plate.

[0013] In the above technical solution, a grip head is arranged at the outer end of the regulating screw, and the grip head is arranged outside the fixing plate.

[0014] In the above technical solution, a relief notch is arranged at the top of the bracket, and the relief notch is arranged opposite to the support spacing.

[0015] In the above technical solution, linear bearings corresponding to the transverse guide rods one by one are arranged on the vertical plate, and the middle part of the transverse guide rod is slidably connected to the linear bearing.

[0016] Due to the application of the above technical solution, the present utility model has the following advantages compared with the prior art:

[0017] 1.

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0024] Example 1: See Figures 1-3 As shown, a coil unwinding support mechanism includes a frame 1, two vertical plates 2 relatively arranged on the frame 1 and support components 3 respectively arranged on the inner side of a corresponding vertical plate 2, and the support components 3 on both sides are relatively arranged; a coil unwinding distance 15 is formed between the two groups of support components.

[0025] The support assembly 3 includes a bracket 4 and two support bearings 5, the two support bearings 5 are rotatably connected to the inner ends of the bracket 4, and the two support bearings 5 are spaced apart from each other, and a support spacing 6 is formed between the two support bearings 5;

[0026] The outer end of the bracket 4 is slidably connected to the vertical plate 2 via at least two transverse guide rods 7, and the outer end of the transverse guide rod 7 is arranged on the outer side of the vertical plate 2;

[0027] The vertical plate 2 is also threaded with an adjusting screw 8, which is arranged parallel to the transverse guide rod 7, and the inner end of the adjusting screw 8 is rotatably connected to the bracket 4. When the adjusting screw rotates, the bracket is driven to move and move closer to or away from the vertical plate.

[0028] In this embodiment, the film roll 9 is wound on the film unwinding shaft 10 (or the film roll is wound on the outside of a hollow paper tube or a 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 inside of the paper tube, and its two ends are outside the two ends of the paper tube). The two ends of the film unwinding shaft are directly placed in the support spacing of the support components on both sides, and the film roll is in the unwinding spacing. The bottom two sides of the film unwinding shaft are respectively against a support bearing. In the process of pulling the film roll out for unwinding, the film unwinding shaft can be supported by the support bearing. The dead weight of the film roll can prevent the film unwinding shaft from being separated from the support spacing, ensuring the stability and safety during the film unwinding process. Moreover, the installation of the film roll and the disassembly of the film unwinding shaft are convenient and quick. The bracket is connected to the vertical plate on the corresponding side through the transverse guide rod, and then the setting of the adjusting screw is used. By rotating the adjusting screw, the bracket can be driven to move relative to the corresponding vertical plate through the transverse guide rod to adjust the distance between the two groups of brackets. In this way, a film roll of corresponding width can use a film unwinding shaft of corresponding length, which can be suitable for film unwinding shafts of different lengths. The smaller the width of the film roll, the shorter the film unwinding shaft can be used. In this way, the film unwinding shaft is stressed as much as possible and the stress is more even, so that the film unwinding shaft is not easy to deform, the service life is extended, and the stability of film unwinding is guaranteed.

[0029] See also Figure 3 As shown, a fixed plate 11 is also provided on the outer side of each vertical plate 2, the outer end of the transverse guide rod 7 is fixedly connected to the fixed plate 11, the outer end of the adjusting screw 8 passes through the fixed plate 11 and is provided on the outer side of the fixed plate 11, and the adjusting screw 8 is rotatably connected to the fixed plate 11.

[0030] The setting of the fixing plate is used to connect the outer end of the transverse guide rod and to be rotatably connected with the adjusting screw, so that the transverse guide rod and the adjusting screw can be limited (the outer end of the adjusting screw will not move axially relative to the fixing plate), and the transverse guide rod and the adjusting screw outside the vertical rod are prevented from being deformed, so as to ensure that the transverse guide rod can be smoothly slidably connected with the vertical plate, and the adjusting screw can be stably screwed with the vertical plate, so as to prevent the 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. In addition, the combination of the fixing plate and the bracket can prevent the transverse guide rod from being separated from the bracket, and limit the axial movement distance of the transverse guide rod.

[0031] See also Figure 3 As shown, the outer end of the adjusting screw 8 is provided with a gripping head 12, and the gripping head 12 is arranged on the outer side of the fixing plate 11. The arrangement 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 for tools to drive the adjusting screw to rotate.

[0032] See also Figure 3As shown, a relief notch 13 is provided at the top of the bracket 4, and the relief notch 13 is disposed opposite to the support spacing 6. The provision of the relief notch can provide clearance for the end of the film unwinding shaft, preventing the film unwinding shaft from coming into contact with the bracket during installation and causing the film unwinding shaft to be unable to be smoothly placed on the support bearing. The end of the film unwinding shaft is placed into the relief notch, and in this way, the relief notch can also limit the film unwinding shaft, preventing the film unwinding shaft from moving forward and backward and disengaging from the support bearing, thus avoiding the problem of dropping.

[0033] Further, linear bearings 14 corresponding to the transverse guide rods 7 one by one are provided on the vertical plate 2, and the middle of each transverse guide rod 7 is slidably connected to one of the linear bearings 14. The provision of the linear bearings makes the movement of the transverse guide rods smoother and reduces the occurrence of jamming.
