[0001] This invention relates to an automatic bonding machine, specifically an FPC automatic bonding machine, belonging to the field of automation control technology. Background Technology

[0002] The fully automatic laminating machine is designed specifically for the production characteristics of small displays and small touch components. It is an essential piece of equipment in LCD manufacturing, used in the post-production processes of LCD displays. It attaches polarizing films to the front and back surfaces of the formed LCD glass substrate according to the polarization angle. It is also suitable for various assembly processes of touch components and window protection components. It can perform pressure-sensitive lamination between various materials such as film / film / film / B glass substrates and film-to-acrylic panels. It boasts advantages such as high efficiency, convenient alignment, and high product yield, overcoming the drawbacks of manual lamination such as bubbles, wrinkles, halos, and watermarks. While reducing the intensity of manual labor, it also eliminates excessive reliance on operator skill. The equipment is equipped with a multi-directional fine-tuning device suitable for products of different shapes. With specialized fixtures, it can also laminate irregularly shaped products such as arcs and rhombuses. The upper and lower platforms utilize vacuum adsorption, equipped with internationally renowned pneumatic components, precision lead screws, and brand-name motors, moving precisely under the command of a central PLC. It is a powerful tool in the production process of small modules and touch components and other optical products.

[0003] Flexible printed circuit boards (FPCs), also known as flexible circuit boards or flexographic circuit boards, are favored for their excellent properties such as light weight, thinness, and ability to be freely bent and folded. However, in China, the quality inspection of FPCs still mainly relies on manual visual inspection, which is costly and inefficient. With the rapid development of the electronics industry, circuit board design is becoming increasingly high-precision and high-density, and traditional manual inspection methods can no longer meet production needs. Automated inspection of FPC defects has become an inevitable trend in the industry's development.

[0004] With the continuous development of flexible printed circuit board (FPC) application technology, the forms and sizes of FPCs are becoming increasingly diverse, requiring a variety of matching automated equipment. Currently, the pace of upgrading automated equipment cannot keep up with the rapid development of FPCs, and more and more FPCs are undergoing a shift from manual to automated production. This necessitates new equipment deeply adapted to the production methods to complete the transformation to automated production, changing the current situation of low efficiency and unstable quality in manual production.

[0005] In view of this, an automatic FPC bonding machine is proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic FPC bonding machine to solve the above-mentioned problems. It can alternately load two fixtures through two independently movable Y-axis mechanisms, reducing the wear and tear on the equipment CT caused by fixture loading and unloading. It adopts a dual bonding head, which can bond 2 PCS of auxiliary materials at the same time, thus improving production efficiency.

[0007] The present invention achieves the above-mentioned objectives through the following technical solution: an automatic FPC bonding machine, comprising a frame, an X-axis assembly, a fixture loading and unloading arm, a belt conveyor, a dual Y-axis moving mechanism, a sheet feeder, an auxiliary material CCD, and a bottom CCD. The X-axis assembly includes an X-axis gantry, dual bonding heads, and an upper CCD. The fixture loading and unloading arm includes a loading arm and a unloading arm. The loading arm can be intelligently controlled to move above the belt conveyor to pick up the material. After a single fixture is bonded, the Y-axis mechanism moves to deliver the fixture below the path of the unloading arm. The unloading arm picks up the fixture and places it on top of the belt conveyor. The bottom of the dual Y-axis moving mechanism is provided with two slides, both of which are mounted on the top of the frame by several bolts. Each of the two slides is provided with a fixture fixing module on its top. The sheet feeder includes a waste box, a stacking platform, a moving arm, a peeling platform, and a support platform.

[0008] Furthermore, the X-axis assembly is installed on the right side of the top of the frame, the X-axis gantry is installed on the top of the frame, and the movement direction of the X-axis assembly is perpendicular to the movement direction of the dual Y-axis moving mechanism on the top of the frame. The dual placement head is located on the left side of the X-axis gantry, and the upper CCD is located on the left side of the X-axis gantry, with the upper CCD located behind the dual placement head. Both the dual placement head and the upper CCD can move back and forth independently along the X-axis direction. The independent movement of the upper CCD can effectively improve the efficiency of the equipment during operation. The dual placement head can take pictures and position the FPC in advance when picking up materials, thereby speeding up the placement CT.

[0009] Furthermore, the fixture loading and unloading arms are installed on the top of the frame and are located on the left side of the X-axis assembly. The fixture loading and unloading arms are arranged parallel to the X-axis assembly, and the loading arm is located on the left side of the unloading arm. The loading arm is on one side of the frame edge and the unloading arm is on the opposite side. Both the loading arm and the unloading arm can move back and forth along the X-direction to complete loading and unloading. While the loading arm is loading along the Y-axis mechanism, the unloading arm can unload along the Y-axis mechanism. The two can be carried out independently and simultaneously, effectively improving production efficiency.

[0010] Furthermore, the belt conveyor is located at the rear of the frame, and both slides are fixedly connected to the top of the frame. Both slides are located at the bottom of the fixture loading and unloading arms. The belt conveyor is used for material feeding during the production process. The belt transmission direction is parallel to the direction of the dual Y-axis moving mechanism. A blocking assembly is installed on the belt transmission route. After the fixture is in place, it will stop at a fixed position, waiting for the loading arm to pick up the material.

[0011] Furthermore, both fixture fixing modules are located at the bottom of the unloading arm, the sheet feeder is installed on the top of the frame and is located in front of the fixture unloading arm. The sheet feeder is installed on the edge of the frame, and the feeder feeding direction is installed along the Y direction, parallel to the dual Y-axis moving mechanism. The incoming material is sheet material, and the auxiliary material on the sheet material can be peeled off on the peeling table for the mounting head to pick up. In addition to moving along the Y direction, the feeder moving arm can also move along the X-axis direction, and can throw the separator between the sheets into the feeder waste box along the X direction.

[0012] Furthermore, the stripping table is located on top of the support platform, and the movable arm is located on top of the support platform, with the movable arm positioned to the left of the stripping table. The movable arm picks up material from the stacking platform and strips it onto the stripping table, thus providing continuous material supply to the stripping table.

[0013] Furthermore, the stacking platform is located on top of the support platform. The stacking platform is used for stacking sheet materials and auxiliary materials, and the stacking platform is located on the left side of the moving arm, which facilitates the moving arm to automatically pick up materials on the stacking platform. The waste box is located on top of the support platform. The waste box is used to collect the interlayer paper between the sheets to prevent waste from being scattered on the frame and hindering the bonding progress.

[0014] Furthermore, the waste box is located in front of the stacking platform, the auxiliary material CCD is installed on the top of the frame, the light source is installed in a direction parallel to the X-axis combination, and both the camera and the light source can be rotated and adjusted in angle. The auxiliary material CCD is set behind the sheet feeder, and the camera can take pictures and identify the stripped material on the feeder support platform. After software calculation, relevant parameters such as the feeding angle and position of the feeding head can be obtained.

[0015] Furthermore, the auxiliary material CCD is located between the X-axis assembly and the fixture loading / unloading arm, the bottom CCD is installed on the top of the frame, and the bottom CCD is located to the right of the auxiliary material CCD and directly below the X-axis assembly placement head movement path. It is responsible for taking pictures and recognizing the auxiliary material picked up by the placement head, calculating the bonding position and angle, and throwing the auxiliary material into the throwing box when the auxiliary material picked up by the placement head does not meet the requirements.

[0016] The technical effects and advantages of this invention are as follows:

[0017] 1. This invention uses a dual-head applicator, which can apply 2 pieces of auxiliary material at the same time, thus improving production efficiency.

[0018] 2. The upper CCD and the dual mounting heads of this invention can move independently. The mounting head can pick up the material or the bottom CCD can take pictures and identify and photograph the FPC at the same time, which effectively reduces the mounting CT.

[0019] 3. The loading and unloading arms of the present invention are integrated into the same mechanism, which significantly improves space utilization and reduces equipment size.

[0020] 4. The present invention is equipped with two independently movable Y-axis mechanisms, which can alternately load two fixtures, reducing the wear and tear on the equipment CT during fixture loading and unloading. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-6 As shown, an automatic FPC bonding machine includes a frame 1, an X-axis assembly 2, a jig loading and unloading arm 3, a belt conveyor 4, a dual Y-axis moving mechanism 5, a sheet feeder 6, an auxiliary material CCD 7, and a bottom CCD 8. The auxiliary material CCD 7 takes pictures and identifies the auxiliary material placed on top of the support platform 6e, and calculates the coordinates and angles required for the bonding head to pick up the material. The X-axis assembly 2 includes an X-axis gantry 2a, dual bonding heads 2b, and an upper CCD 2c, where the X-axis is the forward and backward movement trajectory, and the Y-axis is the left and right movement trajectory. The dual bonding heads 2b move above the feeder support platform 6e, and the two bonding heads descend to alternately pick up the auxiliary material. After picking up the material, they move above the bottom CCD 8 to process the picked-up auxiliary material. The system uses image recognition to calculate the position and angle of the auxiliary material using software. It employs a dual-mount head 2b, which can mount 2 pieces of auxiliary material simultaneously, thus improving production efficiency. The fixture loading and unloading arms 3 include a loading arm 3a and an unloading arm 3b. The bottom of the dual Y-axis moving mechanism 5 is equipped with two slides 9. The two moving mechanisms in the dual Y-axis moving mechanism 5 are installed parallel to each other and are perpendicular to the X-axis combination 2. They can move back and forth along the Y direction, and can continuously load two fixtures at a time, helping to reduce loading waste CT. The top of each slide 9 is equipped with a fixture fixing module 5a. The sheet feeder 6 includes a waste box 6a, a stacking platform 6b, a moving arm 6c, a peeling platform 6d, and a support platform 6e.

[0030] X-axis assembly 2 is installed on the right side of the top of frame 1. Dual placement heads 2b are located on the left side of X-axis gantry 2a. Upper CCD 2c is located on the left side of X-axis gantry 2a and behind dual placement heads 2b. Both placement heads in dual placement heads 2b can move up and down independently, and the placement head suction mechanism can rotate 360° freely. The two placement heads can pick up two pieces of material at a time and then alternately bond them, thereby effectively improving the efficiency of the placement process and reducing placement CT. Fixture loading and unloading arms 3 are installed on the top of frame 1 and are located on the left side of X-axis assembly 2. Loading arm 3a is located on the left side of unloading arm 3b. The loading and unloading arms are integrated into the same mechanism, which significantly improves space utilization and reduces the size of the equipment. Belt conveyor 4 is located behind frame 1. Two slides 9 are fixedly connected to the top of frame 1 and are located at the bottom of fixture loading and unloading arms 3.

[0031] Both fixture fixing modules 5a are located at the bottom of the unloading arm 3b. The sheet feeder 6 is installed on the top of the frame 1 and is located in front of the fixture unloading arm 3. The stripping table 6d is set on the top of the support table 6e. The moving arm 6c is set on the top of the support table 6e and is located to the left of the stripping table 6d. The stacking table 6b is set on the top of the support table 6e and is located to the left of the moving arm 6c. The waste box 6a is set on the top of the support table 6e and is located in front of the stacking table 6b. The auxiliary material CCD 7 is installed on the top of the frame 1 and is located behind the sheet feeder 6. The auxiliary material CCD 7 is located between the X-axis assembly 2 and the fixture unloading arm 3. The bottom CCD 8 is installed on the top of the frame 1 and is located to the right of the auxiliary material CCD 7.

[0032] Before operation, the sheet material is stacked on top of the stacking platform 6b in the sheet material feeder 6. During operation, the loading arm 3a is activated, moving it above the belt conveyor 4 to await material retrieval. Simultaneously, the moving arm 6c in the sheet material feeder 6 picks up a sheet from the stacking platform 6b and places it on the stripping platform 6d for stripping. After the feeder stripping is completed, the auxiliary material CCD 7 takes a picture of the auxiliary material on the support platform 6e to calculate the coordinates and angles required for the mounting head to pick up the material. Then, the dual mounting head 2b moves to the feeder support. Above platform 6e, two placement heads descend alternately to pick up auxiliary materials. After picking up the materials, they move to the top of bottom CCD8 to take pictures and identify the picked-up materials. The software calculates the current position and angle of the auxiliary materials. At the same time, auxiliary material CCD7 continues to take pictures and identify the auxiliary materials on the stripping platform 6d. After the belt conveyor 4 delivers the fixture into place, the loading arm 3a descends to pick up the materials. After descending into place, the cylinder clamps the fixture, and then it rises and moves to place the fixture on the fixture fixing module 5a. The cylinder releases, and the fixing module cylinder clamps the fixture to fix it. Then, one of the Y-axis mechanisms in the dual Y-axis moving mechanism 5 moves the fixture below the moving path of the upper CCD 2c. The upper CCD 2c takes pictures of the FPC bonding points on the fixture and positions them. At the same time, the loading arm 3a moves above the belt conveyor 4. When the next fixture is in place, the loading arm 3a descends to pick up the fixture and places it on the other Y-axis moving mechanism. Then, the picture recognition steps of the upper CCD 2c are repeated. After recognition, the mounting head moves above the fixture and performs bonding alternately according to the position coordinates calculated by the software. After bonding, the mounting head returns to the support platform 6e in the sheet feeder 6 to pick up the material. The upper CCD 2c moves above the fixture to take pictures of the other bonding points and then repeats the bonding steps until the FPCs on the loaded fixtures are bonded. After a single fixture is bonded, the Y-axis mechanism moves the fixture below the moving path of the unloading arm 3b. The unloading arm 3b picks up the fixture and places it on the belt conveyor 4. At the same time, the loading arm 3a picks up the newly arrived fixture and places it on the Y-axis moving mechanism. After the sheet material and auxiliary materials are fully bonded, the moving arm 6c picks up another sheet material and places it on top of the peeling table 6d to continue peeling and feeding. This cycle is repeated until the material production is completed.
