Description

Technical Field

[0001] This invention relates to the field of chip packaging technology, and more specifically to a chip packaging framework gripping structure. Background Technology

[0002] In the chip manufacturing process, a frame for carrying the chip must first be manufactured, and then the die is placed and attached to the frame. When manufacturing the frame, a copper substrate is first placed within the production frame, and then the substrate is etched to form the chip frame. The entire production frame with the die is then transferred to the next process.

[0003] Existing chip packaging frame gripping structures typically use multiple suction cups to grip the edges of the production frame for easy movement. However, in order to set up as many chip frames as possible in a single processing run, the edges of the production frame are relatively narrow. In order to stably grip the production frame, the suction cups need to correspond to the corners and other positions of the production frame. Moreover, the size of the production frame used in different chip packaging processes is not exactly the same. As a result, during the assembly and debugging of the suction cups before production and installation, the position of the suction cups needs to be repeatedly adjusted and calibrated, which further leads to low gripping efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing chip packaging frame gripping structures require repeated adjustments and calibrations of the suction cup position during the assembly and debugging process before production and installation, which leads to low gripping efficiency. Therefore, this invention proposes a new chip packaging frame gripping structure.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a chip packaging frame gripping structure, including a substrate, wherein a mounting base is fixedly mounted on one side surface of the substrate.

[0006] The substrate surface is provided with a positioning device, the positioning device includes two support columns, the two support columns are fixedly installed on the surface of the substrate, and a connecting seat is fixedly installed at the end of the two support columns away from the substrate, and two round holes are opened on one side surface of the connecting seat. Multiple air inlet pipes are fixedly installed on the top surface of the connector, and an air outlet pipe is fixedly installed on one side surface of the connector.

[0007] Preferably, the surface of the substrate has two first through slots, and a slide rod is fixedly installed between the inner walls of the two first through slots on both sides. Two slide plates are slidably connected to the surface of the slide rods. A positioning frame is fixedly installed on the bottom surface of the slide plates. A groove is formed on one side surface of the positioning frame. An L-shaped plate is slidably connected inside the groove. A connecting rod is fixedly installed on the surface of the vertical end of the L-shaped plate. A hollow tube is fixedly installed at the end of the connecting rod away from the L-shaped plate.

[0008] Preferably, a suction cup is fixedly installed on the bottom surface of the hollow tube, a connecting pipe connects the hollow tube and the air inlet pipe, a motor is fixedly installed on the vertical end of the L-shaped plate, a gear is fixedly installed on the output end of the motor, and a rack is fixedly installed on the surface of the positioning frame.

[0009] Preferably, the gear and rack mesh with each other, and the L-shaped plate is slidably connected by the gear, rack and groove.

[0010] Preferably, the surface of the positioning frame is provided with a second through groove, and the hollow tube is slidably connected inside the second through groove by means of a connecting rod.

[0011] Preferably, the air intake pipes are distributed along the length of the circular holes and are respectively connected to the circular holes, and the air outlet pipes pass through each circular hole, so that multiple circular holes are connected to the air outlet pipes.

[0012] Preferably, the surface of the substrate is provided with an adjustment device, which includes four fixing plates. The four fixing plates are symmetrically distributed on the surface of the substrate in pairs, and a threaded rod is rotatably connected between each pair of fixing plates.

[0013] Preferably, a rotating wheel is fixedly mounted on the surface of the threaded rod, and the threads on the surface of the threaded rod are mutually opposite threads with the rotating wheel as the center.

[0014] Preferably, the surface of the substrate has two movable grooves, and the surface of the threaded rod is threadedly connected to two movable plates.

[0015] Preferably, a short rod is fixedly installed on one side surface of each of the movable plates, and the end of the short rod away from the movable plate is fixedly connected to the sliding plate.

[0016] The beneficial effects of this invention are as follows: In this invention, by setting a positioning device, when the position of the suction cup needs to be adjusted, the motor can be started first. The motor starts and drives the gear to rotate. The gear rotates and meshes with the rack, thereby causing the L-shaped plate to move inside the groove. The movement of the L-shaped plate inside the groove drives the connecting rod and the hollow tube to move. The hollow tube moves inside the second through groove and at the same time drives the suction cup to move, thereby changing the position of the suction cup. This allows the position of the suction cup to be determined directly during the debugging process, eliminating the need for multiple adjustments to the suction cup position, improving debugging efficiency, and simplifying the installation steps.

Detailed Implementation

[0023] The present invention is illustrated below with specific embodiments, but these are not intended to limit the invention.

[0024] Example 1 like Figure 1-7As shown, a chip packaging frame gripping structure includes a substrate 1. A mounting base 2 is fixedly mounted on one side surface of the substrate 1. A positioning device 3 is provided on the surface of the substrate 1. The positioning device 3 includes two support pillars 301, which are fixedly mounted on the surface of the substrate 1. A connecting base 302 is fixedly mounted on the end of the two support pillars 301 away from the substrate 1. Two circular holes 303 are formed on one side surface of the connecting base 302. Multiple air inlet pipes 305 are fixedly mounted on the top surface of the connecting base 302. An air outlet pipe 304 is fixedly mounted on one side surface of the connecting base 302. Two first through slots 306 are formed on the surface of the substrate 1. A sliding rod 307 is fixedly mounted between the inner walls on both sides of the two first through slots 306. The surface of the device has two sliding plates 308. A positioning frame 309 is fixedly installed on the bottom surface of the sliding plate 308. A groove 310 is opened on one side surface of the positioning frame 309. An L-shaped plate 311 is slidably connected inside the groove 310. A connecting rod 312 is fixedly installed on the vertical end of the L-shaped plate 311. A hollow tube 313 is fixedly installed on the end of the connecting rod 312 away from the L-shaped plate 311. A suction cup 319 is fixedly installed on the bottom surface of the hollow tube 313. A connecting pipe 314 connects the hollow tube 313 and the air intake pipe 305. A motor 316 is fixedly installed on the vertical end of the L-shaped plate 311. A gear 317 is fixedly installed on the output end of the motor 316. A rack 318 is fixedly installed on the surface of the positioning frame 309. When the position of the suction cup 319 needs to be adjusted, the motor 316 can be started first. The motor 316 drives the gear 317 to rotate. The rotation of the gear 317 meshes with the rack 318, thereby causing the L-shaped plate 311 to move inside the groove 310. The movement of the L-shaped plate 311 inside the groove 310 drives the connecting rod 312 and the hollow tube 313 to move. The hollow tube 313 moves inside the second through groove 315, which in turn drives the suction cup 319 to move, thereby changing the position of the suction cup 319. This allows the position of the suction cup 319 to be determined directly during the debugging process, eliminating the need for multiple adjustments to the position of the suction cup 319, improving debugging efficiency, and simplifying the installation steps.

[0025] Example 2 Reference Figure 1-7 As shown in this embodiment: the gear 317 and the rack 318 mesh with each other, and the L-shaped plate 311 is slidably connected by the gear 317, the rack 318 and the groove 310. The gear 317 and the rack 318 enable the L-shaped plate 311 to move inside the groove 310.

[0026] Reference Figure 1-7 As shown in this embodiment: the surface of the positioning frame 309 is provided with a second through groove 315, and the hollow tube 313 is slidably connected inside the second through groove 315 by means of a connecting rod 312. The setting of the connecting rod 312 has the effect of driving the hollow tube 313 to move inside the second through groove 315.

[0027] Example 3 Reference Figure 1-7 As shown in this embodiment: the air intake pipe 305 is distributed along the length of the circular hole 303 and is connected to the circular hole 303 respectively, and the air outlet pipe 304 passes through each circular hole 303, so that multiple circular holes 303 are connected to the air outlet pipe 304, which can create a negative pressure effect in the connecting seat 302.

[0028] Working principle: When the device is needed, the base plate 1 is first connected to the motion unit using the mounting base 2, and the base plate 1 is moved to a predetermined position by the motion unit. The motion unit can be a slider on a slide rail, the end of a robotic arm, the piston rod of a cylinder, or other devices used to move objects. Then, the two round holes 303 are sealed by plugging the plugs, and then the air outlet pipe 304 of the connecting base 302 is connected to the negative pressure generating device.

[0029] When the frame needs to be gripped, the position of the suction cup 319 is first adjusted according to the gripping part of the frame. The motor 316 is started first, which drives the gear 317 to rotate. The gear 317 rotates and meshes with the rack 318, thereby causing the L-shaped plate 311 to move inside the groove 310. The movement of the L-shaped plate 311 inside the groove 310 drives the connecting rod 312 to move. The movement of the connecting rod 312 drives the hollow tube 313 to move inside the second through groove 315. The movement of the hollow tube 313 inside the second through groove 315 drives the suction cup 319 to move. When the suction cup 319 is aligned and in contact with the predetermined position of the frame, the motor 316 is turned off. At this time, the negative pressure generating device is started, which generates negative pressure inside the connecting seat 302, thereby generating negative pressure inside the hollow tube 313. Finally, the suction cup 319 is used to adsorb and grip the frame. The cooperation of the above structure facilitates the equipment debugging process.

[0030] The suction cup 319 is directly contacted with the frame to determine its position. Then, the position of the hollow tube 313 is fixed by the connecting tube 314, so that the suction cup 319 can be fixed by the position of the hollow tube 313 after it is separated from the frame. This avoids the need for multiple adjustments due to the positional deviation between the suction cup 319 and the frame, and improves the efficiency of equipment debugging. When it is necessary to adjust the distance between the two positioning frames 309 according to the size of the frame, first rotate the wheel 43. The rotation of the wheel 43 drives the threaded rod 42 to rotate. Since the threads on the surface of the threaded rod 42 are opposite to each other with the wheel 43 as the center, when the wheel 43 drives the threaded rod 42 to rotate, the two movable plates 45 connected by the threads on its surface will move away from or towards each other inside the moving groove 44.

[0031] The two movable plates 45 move away from or towards each other inside the moving groove 44, causing the corresponding short rods 46 to move away from or towards each other. The movement of the corresponding short rods 46 in the direction of moving away from or towards each other causes the two sliding plates 308 on the surface of the sliding rod 307 to move away from or towards each other. The movement of the two sliding plates 308 on the surface of the sliding rod 307 in the direction of moving away from or towards each other causes the two positioning frames 309 to move away from or towards each other. The movement of the two positioning frames 309 in the direction of moving away from or towards each other ultimately causes the hollow tube 313 to move away from or towards each other, so that the distance between the two positioning frames 309 conforms to the size of the frame, further improving the applicability of the device.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the present invention without departing from the spirit and scope of the present invention. Any modifications or partial substitutions should be covered within the scope of the claims of the present invention.
