[0023] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The fixing device of the blue film of the chip test and receiving tray involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0024] Reference Figures 1 to 5 The utility model provides a fixing device for a blue film tray for chip testing and receiving materials, including an operating table assembly 1 and a control panel 5. The operating table assembly 1 includes a protective box 101. Two groups of winding roller assemblies 3 are arranged on the inner side of the protective box 101. Limiting grooves 102 are opened on both sides of the top of the protective box 101. The surface of the winding roller assembly 3 is used to place the blue film body 200. The two ends of the blue film body 200 are respectively fixedly connected to the outer sides of the winding roller assemblies 3 on both sides. The two groups of winding roller assemblies 3 rotate synchronously to drive the blue film body 200 to move to the other side. The limiting grooves 102 are used to limit the blue film body 200.
[0025] In a preferred embodiment, the winding roller assembly 3 includes a roller body 301, a second limiting plate 305 is fixedly connected to the back of the roller body 301, a convex driven wheel 306 is fixedly connected to the back of the second limiting plate 305, a conveyor belt 6 is movably mounted on the outer side of the front of the convex driven wheel 306, the outer side of the convex driven wheel 306 is meshed with the inner side of the conveyor belt 6, and a motor 7 is fixedly connected to the back of the convex driven wheel 306 on one side;
[0026] Specifically, the starting motor 7 drives the convex driven wheel 306 to rotate. When the convex driven wheel 306 on one side rotates, the second limit plate 305 on the other side rotates synchronously under the drive of the conveyor belt 6, so that the second limit plates 305 and the roller body 301 on both sides rotate synchronously, and the roller body 301 on one side unwinds and the roller body 301 on the other side rewinds to move the blue film body 200.
[0027] In a preferred embodiment, the top of the protection box 101 is fixedly connected to a mounting seat on the front and back sides of the limiting groove 102, and a guide roller 4 is fixedly connected between the mounting seats of adjacent protection boxes 101, and the blue film body 200 is rotatably arranged on the outside of the guide roller 4;
[0028] Specifically, the guide roller 4 guides the blue film body 200 and ensures that there is a distance between the bottom of the blue film body 200 and the top of the storage table 105 during normal movement, so as not to pull or move the tray on the top of the storage table 105.
[0029] In a preferred embodiment, the front of the protection box 101 is movably connected to a protection door 103 via a hinge, and the top of the protection box 101 is fixedly connected to a storage table 105;
[0030] Specifically, the storage table 105 is used to hold the tray, and the protective door 103 and the protective box 101 jointly protect the winding roller assembly 3 and the blue film body 200 to prevent dust from contaminating the unused blue film body 200.
[0031] In a preferred embodiment, a mounting groove 302 is provided on the front of the roller body 301, a first limiting plate 303 is threadedly connected to the front of the roller body 301, a rotating handle 304 is fixedly connected to the front of the first limiting plate 303, and a bracket 104 is fixedly connected to the front of the inner side of the protective box 101, and the bottom of the first limiting plate 303 is in contact with the top of the bracket 104;
[0032] Specifically, when the first limit plate 303 is not separated from the roller body 301, the first limit plate 303 limits the front of the blue film body 200 to prevent its position from moving, and the first limit plate 303 is threadedly connected to the roller body 301. The roller body 301 is driven by the conveyor belt 6 and the motor 7, and the first limit plate 303 will also move accordingly, that is, the first limit plate 303 can rotate normally on the top of the bracket 104, and the first limit plate 303 can be rotated by shaking the handle 304, but the roller body 301 cannot rotate because the convex driven wheel 306 is in the off state of the motor 7. Rotating the first limit plate 303 can separate the first limit plate 303 from the roller body 301.
[0033] In a preferred embodiment, the thickness of the blue film body 200 is loosely matched with the length of the limiting groove 102 to ensure that the blue film body 200 can pass through the limiting groove 102 normally.
[0034] In a preferred embodiment, the motor 7 is fixedly mounted on the back of the inner side of the protective box 101, and the back of the convex driven wheel 306 on the other side is rotatably connected to the back of the inner side of the protective box 101, and a bearing is provided at the connection;
[0035] Specifically, when the motor 7 is in the off state, since the motor 7 can limit the rotation of the convex driven wheel 306 on one side, and the convex driven wheel 306 on the other side rotates synchronously with the convex driven wheel 306 on one side through the conveyor belt 6, when the motor 7 is turned off, the convex driven wheels 306 on both sides are in a fixed and non-rotatable state.
[0036] In a preferred embodiment, a pressing device 8 is further included, the bottom of which is fixedly connected to the back of the top of the protective box 101, and the pressing device 8 is used to press the blue film body 200;
[0037] Specifically, such as Figure 1 As shown, a pressing device 8 is provided on the top of the operating table assembly 1. After the unused blue film body 200 reaches the top of the storage table 105, the pressing device 8 is pressed down to the top of the blue film body 200 to complete the pressing and packaging operation. After the pressing and packaging is completed, the cut waste is still on the top of the storage table 105. The size of the blue film body 200 needs to be set so that the blue film body 200 as a whole will not be separated after the pressing device 8 completes the cutting, and the unused blue film body 200 can continue to be pushed to the top of the storage table 105 through the conveyor belt 6 and the motor 7.
[0038] The working principle of this utility model:
[0039] When the rolled new blue film body 200 is used for the first time, only one open end of the rolled new blue film body 200 needs to be fixed on the surface of the roller body 301 on the other side, and the rest of the rolled new blue film body 200 is put on the surface of the roller body 301 on one side, and the motor 7 is started to drive the convex driven wheel 306 to rotate. When the convex driven wheel 306 on one side rotates, the second limit plate 305 on the other side rotates synchronously under the drive of the conveyor belt 6, so that the second limit plates 305 on both sides and the roller body 301 rotate synchronously, and the roller body 301 on one side is unwound and the roller body 301 on the other side is unwound. The roller 301 is wound to move the blue film body 200. After the unused blue film body 200 is moved to the top of the storage table 105, the motor 7 is turned off. At this time, the pressing device 8 is pressed down to the top of the blue film body 200 to complete the pressing and packaging operation. After the pressing and packaging is completed, the cut waste is still on the top of the storage table 105. The motor 7 is started again to rewind the waste to the surface of the roller 301 on the other side. The unused blue film body 200 moves to the top of the storage table 105. The cycle is repeated until the blue film body 200 rolled on one side is used up.
[0040] After use, the first limit plate 303 can be separated from the roller body 301 by shaking the handle 304, so that the blue film main body 200 rolled up on the outside of the other side roller body 301 can be directly removed to cut the waste, and the unused blue film main body 200 can be assembled on the outside of one side roller body 301.
[0041] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
