[0003] Processing equipment is installed along the side of the conveyor to perform operations such as chip mounting and inspection on flexible circuit boards, completing the chip mounting process. During production, the chip mounting production line is relatively long, the production speed is not constant, the tape starts and stops intermittently on the production line, the tension of the flexible tape is unstable, and the tape is prone to deviation, bending, and arching, which are unfavorable conditions for chip mounting and make it difficult to achieve successful mounting. Therefore, after mounting, rollers are usually used to roll the chip to ensure that the chip is firmly attached.

[0004] However, the material platform that supports the material strip is usually fixedly installed on the corresponding support base. When the specifications of the chip placement production line change, the machine needs to be stopped first, and then manually disassembled and replaced. Moreover, since the material platform is fixed and locked to the corresponding support base, disassembly is relatively troublesome and it is difficult to quickly adapt to the adjustment of the material platform specifications. The fixed installation of the top rollers is also difficult to adapt to the changes in the height of the chip placement production line. It is impossible to automatically change the roller height and the distance between the roller and the material platform, resulting in low automation and low adjustment efficiency.

[0005] To address the problems in the existing technology, this utility model provides a quick-change rolling mechanism. Utility Model Content

[0026] The present invention will be further described in detail below with reference to specific embodiments:

[0027] The chip mounter system is used for mounting flexible circuit boards. Within the system, the mounting line 4 has several processing stations, each equipped with a feeding mechanism, a rolling mechanism, a mounting mechanism, and a testing mechanism. For example... Figure 1 As shown, this utility model provides a quick-change rolling mechanism, which is located downstream of the feeding mechanism and is used to roll the material strip after feeding and bonding, so that the chip is firmly bonded to the material strip.

[0028] The rolling mechanism is installed on the bonding station 7 of the chip mounting line 4, and includes: rollers 2 and a support platform 1 mounted on the bonding station 7 via a support table 5. The strip moves between the rollers 2 and the support platform 1, and the rollers 2 move on the support platform 1 to roll and press, so that the chip is firmly bonded to the strip. The layout of the rolling mechanism on the chip mounting line 4 is shown in the attached figure. Figure 1 As shown. A lifting drive component 6 is provided at the bottom of the support platform 1. The support platform 1 is detachably connected to the driving end of the lifting drive component 6. For example, the lifting drive component 6 is a slide cylinder.

[0029] Under the action of the lifting drive 6, the support platform 1 can move up and down to adjust its height, so as to adapt to the height of the material conveyor track when the overall height of the chip placement production line 4 is adjusted. In addition, a slide table 10 is installed at the bottom of the support platform 5. The slide table 10 is aligned with the direction of the chip placement production line 4, which can adjust the position of the rolling mechanism along the chip placement production line 4 as a whole.

[0030] Furthermore, the roller 2 is connected to a pressure regulating unit 20 via a transition piece 21. The pressure regulating unit 20 applies pressure to the bottom roller 2, and the pressure is adjustable.

[0031] See attached document Figure 7 As shown, the pressure adjustment unit 20 includes an adjustment head 201, and a spring 203 is mounted on the adjustment head 201 via a pressure rod 202. The bottom of the spring 203 is mounted inside the transition piece 21. A pressure sensor 22 is provided on the pressure rod 202, which can monitor the downward pressure of the roller 2 on the support platform 1.

[0032] See attached document Figure 7 As shown, an observation window is set on the mounting plate on one side of the pressure sensor, which can directly display the rolling pressure value. The rolling pressure can be calculated based on the spring compression and spring elasticity coefficient. When the spring is fatigued, the pressure instability can be detected in time and dealt with in time. Therefore, through the cooperation of the pressure sensor and the spring, the pressure can be fed back in real time, ensuring product quality.

[0033] The adjusting head 201 rises and falls, and the spring 203 is compressed by the pressure rod 202, which drives the transition piece 21 to rise and fall, changing the magnitude of the positive pressure of the bottom roller 2 on the support platform 1.

[0034] Roller 2 is mounted on the second drive component 9 via movable guide rail 8. The second drive component 9 is fixedly mounted on support platform 5. (See attached diagram) Figure 2 As shown, the movable guide rail 8 adopts a combination of guide rail and slider, and the transition piece 21 adopts a fork-shaped connecting vertical plate, and the connecting vertical plate is fixed on the slider of the movable guide rail 8; so that the roller 2 is hoisted and assembled on the movable guide rail 8 as a whole, and can move up and down in the vertical direction, which can change the distance between the roller 2 and the support platform 1.

[0035] See attached document Figure 1 As shown, the slide table 10 is provided with two sets, which respectively carry the lifting drive 6 and the second drive 9. When it is necessary to adjust the position of the roller 2, the adjustment actions of the two sets of slide tables 10 are consistent.

[0036] The second driving component 9 drives the roller 2 and the moving guide rail 8 to move as a whole along the direction perpendicular to the material strip, and rolls and presses the material strip on the station 7. The second driving component 9 is a slide cylinder.

[0037] The support platform 1 is fixedly mounted on the lifting drive component 6 or detachably connected to the lifting drive component 6, as shown in the attached figure.Figure 2 As shown, a schematic diagram is provided showing that the support platform 1 is detachably installed on the lifting drive component 6. The support platform 1 is modular and detachable, which not only allows for flexible adjustment of its position but also enables quick replacement of products of different specifications.

[0038] The following is a detailed description of the support platform 1, based on the fact that the support platform 1 is detachably connected to the drive end of the lifting drive component 6.

[0039] In one or other embodiments, the support platform 1 is placed on the bracket by the clamping member 3. (Refer to the attached document.) Figure 3 The support platform 1 includes a base 11 and several rolled blocks 12, combined with the attached... Figure 4 As shown, the rolling block 12 is detachably installed in the sliding guide groove 13 of the base 11, and the roller 2 adopts a multi-segment combination roller.

[0040] The clamping component 3 is a combination of a gripper 31 and a guide rod cylinder 32. The gripper 31 clamps the base 11 and clamps and limits the entire support platform 1. The position is precisely controlled by the guide rod cylinder 32. The operation is smooth during the adjustment process and the overall structure is compact.

[0041] In another embodiment or other implementation, the support platform 1 is configured as an integral support block 14, which is assembled to the drive end of the base lifting drive 6 by bolts 15, and the roller 2 is an integral cylindrical roller.

[0042] See attached document Figure 5 As shown, the support platform 1 is directly fixed to the bracket by screws. In this embodiment, the support platform 1 is set in a "U" shape, and the roller 2 rolls on the raised surface of the "U" shape. When the specifications and dimensions of the material strip change, the support platform 1 needs to be disassembled and replaced accordingly.

[0043] See attached document Figure 6 The support platform 1 is equipped with two independent L-shaped block mechanisms, which are directly fixed to the bracket by screws. In this embodiment, the roller 2 rolls on the L-shaped protrusion surface.

[0044] In summary, the support platform 1 is designed as a modular assembly structure that can be detachably connected to the lifting drive component 6. Compared with fixed assembly, it does not require machine downtime for replacement and is more convenient to replace. The support platform 1 is fixed by grippers and limited by guide rod cylinders. During operation, its position and spacing are automatically adjusted, making it more efficient and convenient.
