[0020] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] As Figures 1 to 4 shown, a fixture clamping platform for an IC carrier board of the present utility model includes a fixture mounting plate 1, a fixture assembly 2 for placing an IC carrier board 7, and a pressing plate assembly 3. The pressing plate assembly 3 is connected to both sides of the fixture mounting plate 1. The fixture assembly 2 is connected to the fixture mounting plate 1. The fixture assembly 2 is provided with vacuum suction holes 41. The fixture mounting plate 1 is provided with a suction area 11. The fixture mounting plate 1 is provided with a plurality of suction holes 12 in the suction area 11. The suction holes 12 are externally connected to a suction device. The vacuum suction holes 41 are aligned with the suction area 11. When the fixture assembly 2 places the IC carrier board 7, the pressing plate assembly 3 swings above the IC carrier board 7 and presses the IC carrier board 7.

[0022] The lower part of the fixture mounting plate 1 can be installed on the loading and unloading tooling platform on the production line of the IC carrier board 7 and used together with other loading and unloading equipment on the production line. The fixture assembly 2 is detachably connected to the fixture mounting plate 1. After the two are docked, the vacuum holes, the suction area 11, and the suction holes 12 together form a space for suction and vacuum pumping. Through the action of the externally connected suction device, a negative pressure area is generated on the surface of the fixture assembly 2, so that the IC carrier board 7 is easily adsorbed on it. The pressing plate assembly 3 is located on both sides of the fixture mounting plate 1. Through the swing of the pressing plate assembly 3, the pressing and fixing of the IC carrier board 7 on the fixture assembly 2 are realized, achieving the function of pressing the plate, and releasing the fixing of the IC board during unloading.

[0023] The fixture clamping platform for the IC carrier board further includes a sealing ring (not shown in the figure). The fixture mounting plate 1 is provided with a sealing groove 14 on the periphery of the suction area 11. The sealing ring is connected in the sealing groove 14. The fixture assembly 2 and the fixture mounting plate 1 press the sealing ring. Through the setting of the sealing ring, the suction area 11 can have a sealing function, preventing air leakage and causing the vacuum suction holes 41 on the surface of the fixture assembly 2 to not generate negative pressure and unable to adsorb the IC carrier board 7.

[0024] As Figure 5As shown in the figure, the fixture assembly 2 includes a fixture panel 4 and a buckle member 5. The buckle member 5 is connected to both ends of the fixture panel 4. When the fixture panel 4 is connected to the fixture mounting plate 1, it is detachably connected to the end of the fixture mounting plate 1 through the buckle member 5. The fixture assembly 2 is installed above the fixture mounting plate 1. The fixture assembly 2 uses the buckle member 5 of the bayonet type to be fastened above the fixture mounting plate 1, and adopts the easy-to-operate buckle structure to achieve the purpose of quickly and accurately disassembling and replacing the fixture assembly 2 corresponding to different products.

[0025] The fixture assembly 2 further includes a handle 6, and the handle 6 is connected to both ends of the fixture panel 4. With the help of the handle 6, the operator can more easily lift the fixture panel 4, which facilitates the disassembly, installation and replacement of the fixture panel 4.

[0026] The fixture assembly 2 further includes a guide post (not shown in the figure). The fixture panel 4 and the fixture mounting plate 1 are both provided with guide holes at corresponding positions. One end of the guide post is connected to the guide hole 13 of the fixture mounting plate 1, and the other end of the guide post is inserted into the guide hole 42 of the fixture panel 4. A guide post for guiding and positioning the fixture assembly 2 is connected in the guide hole 13 of the fixture mounting plate 1. The channel guide post is positioned and installed with the guide hole 42 of the fixture panel 4, so that the vacuum suction holes 41 of the fixture panel 4 can face its suction area 11, and the docking installation of the fixture panel 4 and the fixture mounting plate 1 is also facilitated in cooperation with the buckle member 5.

[0027] The fixture assembly 2 is designed for quick replacement. The designs of the handle 6, the guide post and the easy-to-remove buckle member 5 meet the quick replacement of fixture assemblies 2 of different sizes.

[0028] As Figure 6 shown in the figure, the pressing plate assembly 3 includes a pressing plate mounting seat 31, a pressing plate cylinder 32, a connecting rod 33, a rotating shaft 34 and a pressing arm 35. The pressing plate mounting seat 31 is connected to both sides of the fixture mounting plate 1. The rotating shaft 34 is movably connected to the pressing plate mounting seat 31. One end of the connecting rod 33 is connected to the rotating shaft 34, and the other end of the connecting rod 33 is connected to the output end of the pressing plate cylinder 32. Pressing arms 35 are respectively connected to both ends of the rotating shaft 34. The pressing plate cylinder 32 drives the rotating shaft 34 to rotate through the connecting rod 33 to drive the pressing arms 35 to swing. One end of the connecting rod 33 is hinged to the output end of the pressing plate cylinder 32, and the position of the other end of the connecting rod 33 is fixed on the rotating shaft 34. The pressing plate cylinder 32 drives one end of the connecting rod 33 to swing, and the other end of the connecting rod 33 drives the rotating shaft 34 to rotate. The pressing arms 35 at both ends also swing with the rotation of the rotating shaft 34. When swinging to contact the IC carrier 7, it presses the IC carrier 7; when the pressing plate cylinder 32 drives in the reverse direction, the pressing arms 35 will swing outwards, so as to release the pressing on the IC carrier 7.

[0029] A fixed bearing 37 is provided on the pressing plate mounting seat 31, and the rotating shaft 34 is connected to the fixed bearing 37. Through the fixed bearing 37, the rotating shaft 34 can rotate more smoothly relative to the pressing plate mounting seat 31.

[0030] The pressing plate assembly 3 further includes a pressing block 36, which is connected to the end of the pressing arm 35. The pressing block 36 is provided with a sliding groove, and the pressing block 36 is slidably connected to the end of the pressing arm 35 through the sliding groove. The pressing block 36 is in direct contact with the IC carrier 7 and will adjust its position relative to the IC carrier 7 as the swing arm swings; the pressing block 36 can be made of a soft material to prevent direct damage to the IC carrier 7 when contacting it. The slidable design between the pressing block 36 and the end of the pressing arm 35 can adjust the position of the pressing block 36 according to the sizes of different IC carriers 7, so as to meet the pressing requirements for different IC carriers 7.

[0031] The working principle of the fixture clamping platform for this IC carrier is as follows:

[0032] The fixture panel 4 is aligned with the guide posts on the fixture mounting plate 1 through the guide holes. After the fixture panel 4 is placed on the fixture mounting plate 1, the fixture panel 4 is fixed to the fixture mounting plate 1 by the buckle member 5. At this time, the vacuum suction holes 41 of the fixture panel 4 are aligned with the suction area 11 on the fixture mounting plate 1, and the sealing ring is pressed by both of them, so that the surrounding of the suction area 11 reaches a sealed effect. The external suction device performs a vacuum pumping operation through the suction hole 12, so that a negative pressure is generated at the vacuum suction holes 41 on the surface of the fixture panel 4. When the feeding mechanism places the IC carrier 7 on the fixture panel 4, the IC carrier 7 is adsorbed. At the same time, the pressing plate cylinder 32 drives the rotating shaft 34 to rotate through the connecting rod 33, so as to drive the pressing arm 35 to swing until the pressing block 36 presses the IC carrier 7, thereby further fixing the IC carrier 7. When the IC carrier 7 is unloaded, the pressing plate cylinder 32 drives in the reverse direction to make the pressing arm 35 move away from the IC carrier 7, and at the same time stops the vacuum pumping operation. Wait for the unloading mechanism to take away the IC carrier 7.

[0033] The fixture clamping platform for this IC carrier has a simple and reliable structure, accurate positioning, convenient disassembly, and is applicable to various automated combination structures.
