[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0045] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0046] In the prior art, when a chip is installed on a flexible circuit board, the flexible circuit board needs to be covered on two opposite surfaces of the chip. Usually, the flexible circuit board is manually lowered with tweezers for manual bending, attachment, pressing and other operations to achieve the installation of the chip and the flexible circuit board. However, manual operation has a slow processing speed and low processing efficiency, and manual operation cannot ensure that the pressure is the same each time, resulting in inconsistent product quality and low product yield.

[0047] In order to solve the above problems, the present invention provides a tool 100 for attaching a chip to a flexible circuit board.

[0048] Please combine Figure 1 , Figure 2 and Fig. 9The tooling 100 for attaching a chip and a flexible circuit board of this embodiment comprises a workbench 1, an upper push mechanism 2 and a movable mechanism 3. A pressing position 14 is provided on the workbench 1. The pressing position 14 is used to place a flexible circuit board 6 and a chip 5. The flexible circuit board 6 has a first pressing area 61 and a second pressing area 62 other than the first pressing area 61, wherein the first pressing area 61 is padded between the workbench 1 and the chip 5, and the second pressing area 62 is located outside the chip 5; the upper push mechanism 2 is installed on the workbench 1 and is located below the pressing position 14. The upper push mechanism 2 is used to move upward to lift the second pressing area 62; the movable mechanism 3 is installed on the workbench 1. The movable mechanism 3 is used to push the lifted second pressing area 62 horizontally to the top of the chip 5, and move downward to press the second pressing area 62, so that the first pressing area 61 and the second pressing area 62 are respectively pressed against the bottom and the top of the chip 5, so as to wrap the flexible circuit board 6 around and attach it to the outside of the chip 5.

[0049] The technical solution of the present invention is to place the flexible circuit board 6 and the chip 5 on the pressing position 14 so that the first pressing area 61 of the flexible circuit board 6 is correspondingly padded at the bottom of the chip 5, and then the second pressing area 62 of the flexible circuit board 6 is pushed from a horizontal state to a state at an angle to the horizontal plane by the upper pushing mechanism 2, so as to facilitate the subsequent movable mechanism 3 to push the second pressing area 62. After the second pressing area 62 is at an angle to the horizontal plane, the movable mechanism 3 is located on the side of the second pressing area 62 away from the chip 5, and then moves toward the chip 5 to push the second pressing area 62 toward the chip 5 until the chip 5 is pressed on the top of the chip 5. At this time, the first pressing area 61 and the second pressing area 62 are respectively located on the opposite sides of the chip 5, and then the movable mechanism 3 is pressed down to apply force to the flexible circuit board 6 and the chip 5, so that the first pressing area 61 and the second pressing area 62 are respectively pressed against the bottom and the top of the chip 5 to attach the flexible circuit board 6 to the outside of the chip 5. The present invention realizes the mechanized attachment and installation of the flexible circuit board 6 and the chip 5 through the cooperation of the lifting mechanism 2 and the movable mechanism 3, thereby improving the processing speed and processing efficiency. At the same time, the lifting and pressing forces of the lifting mechanism 2 and the pressing mechanism can be precisely controlled each time, thereby ensuring that the pressing force on the flexible circuit board 6 and the chip 5 is the same each time, improving the quality consistency of the product, and at the same time improving the product yield.

[0050] Please combine Figures 2 to 5 In one embodiment, the movable mechanism 3 includes a translation component 31 and a pressing component 32. The translation component 31 is installed on the workbench 1, and the pressing component 32 is installed on the translation component 31. The translation component 31 can drive the pressing component 32 to move in the horizontal direction, and is used to push the lifted second clamping area 62 in the horizontal direction to the top of the chip 5; the pressing component 32 can move downward to press the second clamping area 62, so that the first clamping area 61 and the second clamping area 62 are respectively pressed against the bottom and top of the chip 5.

[0051] During use, in the initial state, the translation assembly 31 and the pressing assembly 32 are both located on the side of the second pressing area 62 away from the chip 5, and the distance between the pressing assembly 32 and the surface of the workbench 1 is smaller than the distance between the top of the second pressing area 62 and the surface of the workbench 1, so that the pressing assembly 32 can abut against the second pressing area 62 and push the second pressing area 62. The translation assembly 31 pushes the second pressing area 62 to press the second pressing area 62 on the surface of the chip 5, while driving the pressing assembly 32 to move above the chip 5, and then the pressing assembly 32 moves downward to press the first pressing area 61 and the second pressing area 62 against the bottom and top of the chip 5 respectively, so as to achieve the pressing of the chip 5 and the flexible circuit board 6. Through the cooperation of the translation assembly 31 and the pressing assembly 32, accurate positioning and force control can be achieved to prevent the second pressing area 62 from being pushed off or damaged by excessive force, thereby improving accuracy and safety.

[0052] Furthermore, the moving direction of the translation assembly 31 is perpendicular to the plane where the second clamping area 62 is located, so that the second clamping area 62 can be fitted with the translation assembly 31 at all locations when pushed by the translation assembly 31, thereby making the second clamping area 62 evenly stressed and avoiding damage to the second clamping area 62.

[0053] Specifically, the translation assembly 31 includes a slide rail 311, a slider 312 and a pressure plate 313. The slide rail 311 extends in a horizontal direction. The pressure plate 313 is slidably connected to the slide rail 311 through the slider 312. The pressing assembly 32 is installed on the pressure plate 313, and pushes the pressure plate 313 to move along the slide rail 311 toward the chip 5 to push the second clamping area 62 in a horizontal direction to above the chip 5, and drives the pressing assembly 32 to move in a horizontal direction to above the chip 5.

[0054] The cooperation between the slider 312 and the slide rail 311 can ensure that the pressing plate 313 is stable and smooth during the sliding process without any jamming or shaking, thereby improving the stability and accuracy of the pressing plate 313 in pushing the second clamping area 62. At the same time, the slide rail 311 can limit the sliding direction to prevent the pressing plate 313 from deviating, ensuring that the pressing plate 313 always moves along the predetermined track, and realizing the precise alignment of the second clamping area 62 and the chip 5.

[0055] In one embodiment, a through hole 314 is provided on the pressure plate 313, and the pressing assembly 32 includes a shell 321 and a pressure rod driving member 322 and a pressure rod 323 installed in the shell 321. The shell 321 is installed on the pressure plate 313, and the pressure rod 323 passes through the shell 321 and is provided in the through hole 314. The pressure rod driving member 322 is used to drive the pressure rod 323 to rise and fall vertically so that the pressure rod 323 can pass through the through hole 314 and press against the second clamping area 62, so as to press the top and bottom of the chip 5 against the second clamping area 62 and the first clamping area 61 respectively. The pressure rod 323 is arranged corresponding to the through hole 314 of the pressure plate 313, so that when the pressure plate 313 presses the second clamping part to the top of the chip 5, the pressure rod 323 just corresponds to the top of the chip 5, which is convenient for the pressure rod 323 to perform subsequent pressing operations. At the same time, the through hole 314 also plays a limiting role, which improves the positioning accuracy of the pressure rod 323 and avoids the pressure rod 323 from shifting during the pressing process, so that the chip 5 and the flexible circuit board 6 can be evenly stressed, thereby improving their safety.

[0056] In one embodiment, two in-place magnets 11 are arranged on the workbench 1 at intervals along the extension direction of the slide rail 311, and the two in-place magnets 11 surround a sliding gap 12. A baffle 315 is provided on the slider 312, and the baffle 315 extends into the sliding gap 12 and is used to abut against the two in-place magnets 11 when the slider 312 slides along the slide rail 311. When the baffle 315 abuts against the in-place magnet 11 near the clamping position 14, the pressure rod 323 is correspondingly arranged above the second clamping area 62.

[0057] The two in-position magnets 11 are respectively used to abut against the baffle plate 315 to achieve a positioning effect. When the baffle plate 315 abuts against the in-position magnet 11 close to the clamping position 14, the pressure rod 323 is correspondingly arranged above the second clamping area 62, and there is no need for manual positioning by the operator, which improves the positioning accuracy and convenience, thereby improving the processing efficiency. When the baffle plate 315 abuts against the in-position magnet 11 away from the clamping position 14, it is in an initial state. At this time, the pressing component 32 is located on the side of the second clamping area 62 away from the chip 5, avoiding interference between the pressing component 32 and the upper top block 24. At the same time, the magnetic adsorption of the magnet and the baffle plate 315 can prevent the pressing component 32 and the translation component 31 from moving at will after they are in place, thereby improving accuracy and safety.

[0058] In one embodiment, the pressure rod driving member 322 includes a first elastic connecting member 3221, a connecting block 3222 and a first transmission shaft 3223, one end of the first elastic connecting member 3221 is connected to the shell 321, the pressure rod 323 is connected to the other end of the first elastic connecting member 3221 through the connecting block 3222, two through-holes 3211 are respectively provided on two side walls of the shell 321 opposite to each other in the horizontal direction, the first transmission shaft 3223 is horizontally penetrated in the two sockets 3211 and connected to the connecting block 3222, and the first transmission shaft 3223 is respectively provided with two through-holes 3211 at positions corresponding to the two sockets 3211. The first transmission shaft 3223 is capable of rotating so that the two protrusions 3225 respectively abut against the bottom walls of the two insertion holes 3211, and compress the first elastic connecting member 3221, so that the pressure rod 323 moves upward and disengages from the second clamping area 62; the first transmission shaft 3223 is capable of rotating so that the two first slots 3224 respectively engage with the bottom walls of the two insertion holes 3211, so that the elastic restoring force of the first elastic connecting member 3221 pushes the pressure rod 323 to descend and abut against the second clamping area 62.

[0059] When the first locking nut 3224 is in the unlocking state, the two protrusions 3225 of the first transmission shaft 3223 are respectively in contact with the bottom of the two sockets 3211. At this time, the first transmission shaft 3223 drives the connecting block 3222 to move upward, thereby driving the pressure rod 323 to move upward. The first elastic connecting member 3221 contracts upward and is in a compressed state. When the first transmission shaft 3223 is rotated until its two first slots 3224 are respectively engaged with the bottom walls of the two sockets 3211, the protrusions 3225 cannot be engaged with the bottom walls of the sockets 3211. Under the elastic restoring force of the first elastic connecting member 3221, the first transmission shaft 3223 is pushed downward until the first slots 3224 are engaged with the bottom walls of the sockets 3211. At this time, the pressure rod 323 moves downward under the drive of the connecting block 3222, thereby realizing the downward pressing of the pressure rod 323 and the tightening of the chip 5 and the flexible circuit board 6.

[0060] It should be noted that the downward pressure of the pressure rod 323 can be adjusted by adjusting the elastic modulus of the first elastic connecting piece 3221 and the depth of the first slot 3224. Through the cooperation of the first elastic connecting piece 3221 and the first transmission shaft 3223, the downward pressure and upward movement of the pressure rod 323 can be adjusted by rotating the first rotating shaft, and the first elastic connecting piece 3221 ensures that the downward pressure is the same each time, thereby improving processing efficiency while improving product consistency and product yield.

[0061] In one embodiment, both ends of the first transmission shaft 3223 are exposed outside the housing 321, and a first rotating handle 3226 is provided at one end of the first transmission shaft 3223. By providing a handle at one end of the first transmission shaft 3223, it is easier for an operator to rotate the first transmission shaft 3223 through the first rotating handle 3226, thereby reducing the difficulty of the processing operation. Specifically, the first rotating handle 3226 can be a rod-shaped structure extending in a different direction from the first transmission shaft 3223, thereby forming a longer lever arm, so that the operator can rotate the first transmission shaft 3223 more easily.

[0062] Please combine Figure 2 , Figure 6 and Figure 7 In one embodiment, the upper mechanism 2 includes a second elastic connecting member 21, a second transmission shaft 22, an upper connecting rod 23 and an upper block 24. One end of the second elastic connecting member 21 is connected to the workbench 1. The upper block 24 is connected to the other end of the second elastic connecting member 21 through the upper connecting rod 23. A clamping hole 25 is provided at the bottom of the upper block 24. The second transmission shaft 22 is inserted into the clamping hole 25. A second clamping groove 221 is provided on the second transmission shaft 22. A protrusion 222 is formed on the side of the second transmission shaft 22 away from the second clamping groove 221. An upper top opening 13 is opened on the workbench 1 at a position corresponding to the second clamping area 62; the second transmission shaft 22 can rotate so that the protrusion 222 abuts against the bottom wall of the clamping hole 25, and compresses the second elastic connecting member 21, so that the upper top block 24 moves downward and is accommodated in the upper top opening 13; the second transmission shaft 22 can also rotate so that the second clamping groove 221 is clamped and matched with the bottom wall of the clamping hole 25, so that the elastic restoring force of the second elastic connecting member 21 pushes the upper top block 24 to pass through the upper top opening 13 and move upward and extend out of the workbench 1 to lift the second clamping area 62.

[0063] In the initial state, the protrusion 222 of the second transmission shaft 22 abuts against the bottom wall of the card hole 25. At this time, the upper top block 24 is squeezed and moved downward and accommodated in the upper top opening 13, and drives the second elastic connecting member 21 to be compressed. When the second transmission shaft 22 is rotated until the second card slot 221 is engaged with the bottom wall of the card hole 25, the protrusion 222 cannot abut against the bottom wall of the card hole 25. Under the elastic restoring force of the second elastic connecting member 21, the second transmission shaft 22 is pushed upward until the second card slot 221 is engaged with the bottom wall of the plug hole 3211. At this time, the upper top block 24 moves upward under the push of the second elastic connecting member 21, thereby realizing the push for the second clamping area 62 so that the second clamping area 62 is at an angle with the horizontal plane.

[0064] It should be noted that the distance that the second clamping area 62 is pushed can be adjusted by adjusting the depth of the second card slot 221, and it can be ensured that the height to which the second clamping area 62 is pushed is consistent each time, ensuring that the second clamping area 62 is pressed to the top of the chip 5 in the same posture each time, thereby improving processing efficiency while improving product consistency and product yield.

[0065] In one embodiment, the second transmission shaft 22 is passed through the workbench 1, and both ends of the second transmission shaft 22 are exposed outside the workbench 1, and a second rotating handle 223 is provided at one end of the second transmission shaft 22. By providing a handle at one end of the second transmission shaft 22, it is easier for an operator to rotate the second transmission shaft 22 through the second rotating handle 223, thereby reducing the difficulty of the processing operation. Specifically, the second rotating handle 223 can be a rod-shaped structure extending in a different direction from the second transmission shaft 22, thereby forming a longer lever arm, so that the operator can rotate the second transmission shaft 22 more easily.

[0066] Please combine Figure 3 and Fig. 9 In one embodiment, the pressing position 14 is a pressing groove 15 formed by being recessed downward from the top surface of the workbench, and the pressing groove 15 includes a first area 151 for placing the first pressing area 61 and the chip 5 and a second area 152 for placing the second pressing area 62. The chip 5 and the flexible circuit board 6 are limited in the pressing groove 15, which can prevent the chip 5 and the flexible circuit board 6 from being offset during the processing, thereby improving the alignment accuracy of the chip 5 and the flexible circuit board 6. At the same time, it can ensure that the flexible circuit board 6 is in close contact with the chip 5 during pressing and attaching, reducing the problem of poor attachment caused by position misalignment, thereby improving the quality of the final product.

[0067] Please combine Figure 2 and Figure 8 In one embodiment, the tooling 100 for attaching chips and flexible circuit boards further includes two limit assemblies 4, which are respectively arranged on opposite sides of the first area 151 along the horizontal direction, each limit assembly 4 includes a limit block 44, and the workbench 1 is respectively provided with two movable grooves 16 connected to the clamping groove 15 on opposite sides of the first area 151 along the horizontal direction, and the two limit blocks 44 are respectively arranged in the two movable grooves 16, and the two limit blocks 44 can both move toward the first area 151 to clamp the chip 5, or both move in a direction away from the first area 151 to loosen the chip 5.

[0068] The limit assembly 4 clamps the chip 5 from two opposite sides of the chip 5, further improving the stability of the chip 5, avoiding the chip 5 from offsetting or shifting during the pressing and attaching process, thereby further reducing the problem of poor attachment caused by position misalignment, thereby improving the quality of the final product. The chip 5 is clamped from two opposite sides of the chip 5. It ensures that the chip 5 is evenly stressed, avoids damage to the chip 5, and improves the product yield. The two movable grooves 16 can guide and limit the limit block 44, ensuring that the limit block 44 can accurately clamp the side wall of the chip 5, avoiding offset during the alignment process and causing damage to the chip 5.

[0069] In one embodiment, the limit assembly 4 also includes a guide plate 41, a third elastic connector 42 and a third transmission shaft 43. The guide plate 41 is installed in the workbench 1. The limit block 44 is connected to the guide plate 41 through the third elastic connector 42. A transmission block 431 is provided at a position corresponding to the limit block 44 on the third transmission shaft 43. A concave area 432 recessed toward the first area 151 and a convex area 433 convex in a direction away from the first area 151 are formed on two opposite end surfaces of the transmission block 431; one of the limit blocks 44 is abutted against the concave area 432 or the convex area 433 of one end surface of the transmission block 431 through a transmission rod; the other limit block 44 is abutted against the transmission block 431 through another transmission rod. The concave area 432 or the convex area 433 of the other end face of 431 abuts against the concave area 432 or the convex area 433; the third transmission shaft 43 can rotate so that the convex areas 433 of the transmission block 431 abut against the corresponding transmission rod, so as to drive the corresponding limit blocks 44 to move in the movable groove 16 away from the first area 151 through the transmission rod, and compress the third elastic connecting member 42 so that the two limit blocks 44 loosen the chip 5; the third transmission shaft 43 can also rotate so that the concave areas 432 of the transmission block 431 abut against the corresponding transmission rod, so as to push the corresponding limit blocks 44 to move in the movable groove 16 toward the first area 151 through the elastic restoring force of the third elastic connecting member 42, so that the two limit blocks 44 clamp the chip 5.

[0070] In the initial state, the raised areas 433 on the two end faces of the transmission block 431 are respectively in contact with the two transmission rods. At this time, the transmission rod is squeezed by the raised areas 433 and moves in the direction away from the first area 151, so that the two limit blocks 44 loosen the chip 5 and compress the third elastic connecting member 42; when the third transmission shaft 43 rotates to the concave area 432 of the transmission block 431 and abuts against the transmission rod, the squeezing of the raised areas 433 is lost, and the two limit blocks 44 move toward the direction of the first area 151 under the elastic restoring force of the two third elastic connecting members 42, thereby clamping the chip 5.

[0071] It should be noted that the force with which the limit block 44 clamps the chip 5 can be adjusted by adjusting the depth of the depressed area 432 of the transmission block 431 and the elastic modulus of the third elastic connector 42, and the cooperation between the transmission block 431 and the transmission rod can ensure that the chip 5 is clamped with the same force each time, thereby avoiding damage to the chip 5 due to uneven force or excessive pressure, thereby improving product yield.

[0072] In one embodiment, the third transmission shaft 43 is passed through the workbench 1, and both ends of the third transmission shaft 43 are exposed outside the workbench, and a first rotation handle 3226 is provided at one end of the third transmission shaft 43. By providing a handle at one end of the third transmission shaft 43, it is easier for the operator to rotate the third transmission shaft 43 through the third rotation handle 435, thereby reducing the difficulty of the processing operation. Specifically, the third rotation handle 435 can be a rod-shaped structure with a different extension direction from the third transmission shaft 43, thereby forming a longer force arm, so that the operator can rotate the third transmission shaft 43 more easily.

[0073] See also Figure 3 In one embodiment, the workbench 1 has a top plate 17, the clamping groove 15 and the movable groove 16 are both located on the top plate 17, the guide plate 41 is connected to the top plate 17, and a plurality of long strip-shaped positioning holes 18 are arranged on opposite sides of the top plate 17 corresponding to the first area 151 along the horizontal direction, and each positioning hole 18 extends along the moving direction of the limit block 44, and a plurality of positioning columns 411 are arranged on the top of each guide plate 41, and the plurality of positioning columns 411 are used to be plugged in and matched with the plurality of positioning holes 18 on the same side in the same number and one-to-one correspondence to realize the positioning of the guide plate 41.

[0074] The positioning hole 18 is arranged in a long strip shape, and the insertion position of the positioning column 411 and the positioning hole 18 can be adjusted, thereby adjusting the distance between the limit block 44 and the chip 5, and then adjusting the clamping force of the limit block 44 on the chip 5, thereby increasing the adjustable range of the clamping force of the chip 5 and improving flexibility and applicability.
