Technical Field

[0002] Automatic feeding machines can automatically feed circuit boards to be processed / tested into circuit board processing / testing equipment, which helps to improve production efficiency and is widely used in circuit board production lines.

[0003] For example, Chinese patent document CN217920302U discloses an automatic feeding machine, which includes a chassis, a storage plate module, a robotic arm module, a feeding plate module, and a paper separator receiving box. The robotic arm module includes an adsorption robotic arm with multiple negative pressure suction nozzles and a spatial drive mechanism for driving the adsorption robotic arm. The paper separator receiving box and the feeding plate module are located on opposite sides of the storage plate module in a first horizontal direction. The feeding plate module includes a movable platform and a translation drive mechanism for driving the movable platform to translate. The movable platform is provided with a positioning structure for positioning the circuit board. The robotic arm module is used to place the circuit board stored in the storage plate module onto the movable platform and place the paper separator on the circuit board into the paper separator receiving box.

[0004] For example, the ultra-thin substrates of flexible circuit boards are characterized by their thinness and malleability. When using automatic feeding machines such as those disclosed in the aforementioned patent documents, problems such as product deformation, wrinkling, and stacking can easily occur, making automatic feeding difficult. This problem is even more pronounced on large-area ultra-thin substrates. Therefore, improvements to existing automatic feeding machines are necessary. Utility Model Content

[0005] The main purpose of this invention is to provide an ultra-thin substrate feeding system, which is suitable for feeding ultra-thin substrates.

[0006] To achieve the aforementioned main objectives, this utility model discloses an ultra-thin substrate feeding system, comprising a feeding machine equipped with a frame, a paper-separating robot, a paper-separating receiving box, and a substrate output line. The paper-separating robot is used to place the paper separator from the incoming substrate into the paper-separating receiving box; wherein:

[0007] The substrate output line is provided with a lifting device at the inlet end. The lifting device includes an inlet lifting platform and a first Z-axis lifting module that drives the inlet lifting platform. The inlet lifting platform can lift the substrate inlet upward under the drive of the first Z-axis lifting module.

[0008] The frame is equipped with a translation bracket and a translation module that drives the translation bracket; the translation bracket is located above the substrate output line and the material receiving lifting platform, and can reciprocate between the substrate output line and the material receiving lifting platform.

[0009] A substrate robot is installed at the lower part of the translation bracket. The substrate robot is used to place the substrate from the incoming substrate material onto the substrate output line. The substrate robot includes a substrate suction cup assembly with multiple Bernoulli suction cups.

[0010] Furthermore, the paper receiving box is installed on the upper part of the translation bracket and is vertically overlapped with the substrate robot; the paper robot includes a paper suction cup assembly located above the material receiving lifting platform and a second Z-axis lifting module that drives the paper suction cup assembly to rise and fall.

[0011] Furthermore, the paper-insertion suction cup assembly includes multiple vacuum suction cups.

[0012] Furthermore, the substrate robot includes a third Z-axis lifting module, and the substrate suction cup assembly is directly or indirectly disposed on the third Z-axis lifting module.

[0013] Furthermore, the third Z-axis lifting module is provided with a rotating module; the substrate suction cup assembly is mounted on the rotating module so that it can rotate around the Z-axis.

[0014] Furthermore, one end of the translation bracket is connected to the translation module, and the other end is slidably engaged with the first slide rail mounted on the frame.

[0015] Furthermore, the substrate output line includes a conveyor frame and a conveyor roller assembly rotatably mounted on the conveyor frame, the conveyor roller assembly being used to output the substrate.

[0016] Furthermore, the conveying roller assembly is provided with limiting baffles on both sides of its axial direction for limiting the substrate. The limiting baffles are installed on the second slide rail of the conveying frame and can move along the axial direction of the conveying roller assembly.

[0017] Furthermore, the substrate loading system also includes a trolley, which is equipped with a movable pallet for stacking incoming substrates; wherein the incoming material lifting platform is used to lift the movable pallet to raise the incoming substrates stacked on the movable pallet.

[0018] Furthermore, the trolley has multiple limiting rods that are inserted through the movable pallet and are horizontally adjustable, the limiting rods being used to horizontally limit the incoming substrates stacked on the movable pallet.

[0019] The technical solution of this utility model has the following beneficial effects:

[0020] In this invention, the substrate suction cup assembly of the substrate robot is equipped with multiple Bernoulli suction cups. It does not require external vacuum auxiliary components such as vacuum generators and vacuum pumps, and can work simply by connecting compressed air. It is especially suitable for adsorbing and transporting ultra-thin substrates, effectively preventing product deformation and multiple stacked sheets.

[0021] Furthermore, the paper separator receiving box is installed on the upper part of the translation bracket and overlaps vertically with the substrate robot, which can make full use of the upper space of the translation bracket and help reduce the space occupied by the equipment. During operation, the paper separator suction cup assembly first picks up the paper separator from the substrate and rises to a safe height. After the translation bracket moves to the upper part of the material lifting platform and below the paper separator suction cup assembly, the paper separator suction cup assembly can descend and place the picked-up paper separator into the paper separator receiving box above the translation bracket. At the same time, the substrate robot below the translation bracket can pick up the substrate from the substrate, improving the loading efficiency.

[0022] To more clearly illustrate the purpose, technical solution, and advantages of this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figure 1 and 2As shown, the ultra-thin substrate loading system of this embodiment includes a loading machine 100. The loading machine 100's housing 101 houses a frame 102, a lifting device 110, a paper separator robot 120, a substrate robot 130, a paper separator receiving box 140, and a substrate output line 150. The lifting device 110 is used to lift the stacked substrates, the paper separator robot 120 is used to place the paper separators from the substrates into the paper separator receiving box 140, and the substrate robot 130 is used to place the substrates from the substrates into the substrate output line 150. The paper separators separate adjacent stacked substrates; their material can be paper, film, etc. For simplicity, this invention refers to all substrate separator materials as paper separators.

[0030] In this embodiment, the lifting device 110 is disposed along the X direction at the inlet end of the substrate output line 150. Specifically, the lifting device 110 includes an inlet lifting platform 111 and a first Z-axis lifting module 112 that drives the inlet lifting platform 111. The inlet lifting platform 111 can be lifted and lowered along the lifting slide rail 113 under the drive of the first Z-axis lifting module 112, thereby gradually lifting the substrate to an appropriate height. The first Z-axis lifting module 112 can be a screw lifting module, which includes a motor 112a and a screw transmission mechanism 112b. The motor 112a drives the inlet lifting platform 111 to lift and lower through the screw transmission mechanism 112b.

[0031] like Figure 2 and 3 As shown, a translation bracket 103 and a translation module 104 that drives the translation bracket 103 to move along the X direction are mounted on the frame 102. The translation bracket 103 is positioned above the substrate output line 150 and the incoming material lifting platform 111. One end of the translation bracket 103, perpendicular to the X direction, is connected to the translation module 104 and can reciprocate between the substrate output line 150 and the incoming material lifting platform 111. Preferably, the other end of the translation bracket 103 relative to the translation module 104 is slidably engaged with a first slide rail 105 mounted on the frame 102 to improve the movement stability of the translation bracket 103.

[0032] A substrate robot 130 is mounted on the lower part of the translation bracket 103. It can move together with the translation bracket 130 above the incoming material lifting platform 111 and pick up the substrate from the incoming material at that position. In this embodiment, the substrate robot 130 includes a substrate suction cup assembly 131 and a third Z-axis lifting module 132. The third Z-axis lifting module 132 is fixed on the translation bracket 103, and the substrate suction cup assembly 131 is directly or indirectly disposed on the third Z-axis lifting module 132. The substrate suction cup assembly 131 includes multiple Bernoulli suction cups 131a, which are arranged in a two-dimensional array. Preferably, the third Z-axis lifting module 132 is provided with a rotation module 133, and the substrate suction cup assembly 131 is mounted on the rotation module 133 to rotate around the Z-axis for substrate correction. The rotation module 133 and the third Z-axis lifting module 132 can be ZR motion modules known in the art, and will not be described in detail here.

[0033] In this invention, the Bernoulli suction cup features a dual connector: one for compressed air adsorption and the other for high-pressure air degaussing and vacuum detection. It eliminates the need for external vacuum generators, pumps, or other vacuum auxiliary components; it operates solely with compressed air. This design is particularly suitable for adsorbing and handling ultra-thin substrates, effectively preventing product deformation and multiple sheets stacked. Furthermore, the Bernoulli suction cup boasts strong adsorption force, a fast adsorption and release response frequency, and a backflush function, resulting in rapid release and improved equipment operating speed. The structure of the Bernoulli suction cup itself can be referenced from existing technologies and will not be elaborated upon here.

[0034] The paper separator receiving box 140 is mounted on the upper part of the translation bracket 103 and overlaps with the substrate robot 130 in the vertical direction (Z-axis direction) to make full use of the upper space of the translation bracket 103, which helps to reduce the area / space occupied by the equipment. The paper separator receiving box 140 can move together with the translation bracket 103 to the top of the receiving lifting platform 111 and receive the paper separator at that position. The paper separator robot 120 includes a paper separator suction cup assembly 121 and a second Z-axis lifting module 122 for driving the paper separator suction assembly 121 to rise and fall. For example, the paper separator suction cup assembly 121 includes a plurality of vacuum suction cups 121a.

[0035] During operation, the detection camera / sensor in the feeder 100 first detects whether the top layer of the stacked substrates is a substrate or a spacer. When a spacer is detected, the spacer suction cup assembly 121 picks up the spacer from the substrates being lifted by the lifting device 110 and rises to a safe height. Then, the translation bracket 103 moves above the inlet lifting platform 111 and below the spacer suction cup assembly 121, allowing the spacer suction cup assembly 121 to descend and place the picked-up spacer into the spacer receiving box 140 above the translation bracket 103. Simultaneously, the substrate robot 130 picks up the substrates from the substrates, improving feeding efficiency. After the substrate robot 130 picks up the substrates, the translation bracket 103 moves above the substrate output line 150, and the substrate robot 130 places the substrates onto the substrate output line 150. The substrates are then output from the substrate output line 150 to the outside of the feeder 100 and flow into the next process.

[0036] like Figure 5 As shown, the substrate output line 150 includes a conveyor frame 151 and a conveyor roller assembly 152 rotatably mounted on the conveyor frame 151. The conveyor roller assembly 152 is used to output the substrate to the outside of the feeder 100 along the X direction. Limiting baffles 153 for limiting the substrate are respectively provided on both axial sides of the conveyor roller assembly 152. The limiting baffles 153 are mounted on the second slide rail 154 of the conveyor frame 151 and can move along the axial direction of the conveyor roller assembly 152. By adjusting the position of the limiting baffles 153, the substrate is ensured to be output along the middle of the substrate output line 150.

[0037] Please continue reading. Figure 1 and 2 The substrate loading system of the embodiment also includes a trolley 200, which is provided with a movable pallet 201 for stacking substrate materials. After the trolley 200 is pushed into the housing 101, the material lifting platform 111 is inserted under the movable pallet 201 and carries the movable pallet 201. When the material lifting platform 111 rises, it lifts the movable pallet 201 to raise the substrate materials stacked on the movable pallet 201.

[0038] Furthermore, the trolley 200 also has multiple limiting rods 202 passing through the movable pallet 201, which are used to horizontally limit the incoming substrates stacked on the movable pallet 201. The position of the limiting rods 202 is horizontally adjustable relative to the movable pallet 201 to accommodate substrates of various sizes.

[0039] The ultrathin substrate loading system of this invention can be used not only for loading flexible circuit boards, but also for handling thin / fragile workpieces, such as solar cells, wafers / wafers, thin films, flat panels, thin glass sheets, and large surface area elastic workpieces.

[0040] Although the present invention has been described above through embodiments, it should be understood that any equivalent changes made by those skilled in the art without departing from the scope of the present invention should be covered by the protection scope of the present invention.
