Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board processing, and in particular relates to a piece-by-piece feeding device for stacked circuit boards. Background Art

[0002] Multiple stages of circuit board manufacturing involve the production of printed circuit boards. Existing manual single-piece loading methods are associated with low production efficiency, high workload, and severe limitations on production efficiency. Existing technologies utilize mechanisms such as vacuum suction cups for loading, which offer a more intelligent solution to the inefficiency of manual loading. However, these methods come with high equipment investment costs, complex equipment structures, complex control procedures, and difficult or costly maintenance. Utility Model Content

[0003] The purpose of the utility model is to provide a piece-by-piece loading device for stacked circuit boards, so as to solve the problems of low efficiency of manual single-piece loading or high investment and maintenance costs of automated loading equipment.

[0004] The utility model is achieved through the following technical solutions:

[0005] The utility model provides a stacking type circuit board chip loading device, comprising a conveying mechanism, a bracket, a material storage mechanism, a chip loading mechanism and a rotating loading mechanism arranged on the bracket;

[0006] The storage mechanism includes a storage rack, which is used to vertically stack circuit boards. The storage rack includes an L-shaped vertical plate and a plurality of transverse rods.

[0007] The slicing mechanism is used to separate individual circuit boards from vertically stacked circuit boards; the slicing mechanism includes a driving device and a slicing assembly, the slicing assembly includes a rigid connecting tube and a slicing airbag, the slicing airbag is connected to an air source via the rigid connecting tube, the driving device is connected to the rigid connecting tube and drives the rigid connecting tube to perform horizontal reciprocating motion, and the outer surface of the slicing airbag is provided with a plurality of convex rings forming a tooth-like structure, which is used to separate individual circuit boards from the vertically stacked circuit boards;

[0008] The rotary loading mechanism is used to transfer the single-chip circuit board from the storage mechanism to the conveying mechanism. The rotary loading mechanism includes a rotating assembly and a support arm. The rotating assembly is mounted above the bracket. The support arm is vertically provided on the rotating assembly. The support arm is provided with a U-shaped hook at the end near the rotating assembly. When the support arm is perpendicular to the bracket, the hook is located below the storage rack.

[0009] Based on the above technical solution, the circuit boards can be directly stacked and placed online on the storage rack. The separation of single circuit boards is achieved through the forward and backward movement of the slicing mechanism and the interaction between the toothed structure of the slicing airbag and the bottom of the stacked circuit boards. The separated circuit boards are transformed from a vertical state to a horizontal state through a rotating loading mechanism and transferred to the conveying mechanism to complete the online action. The device can realize automatic single-piece online loading of circuit boards, and the equipment structure and control method are simple, and the online efficiency is high.

[0010] Furthermore, the storage mechanism also includes a moving component, and the storage rack moves back and forth relative to the bracket through the moving component. The moving component includes a drive motor and two sets of conveyor belts. The drive motor simultaneously drives the two sets of conveyor belts to move synchronously. The conveyor belts are respectively arranged along the inner side of the bracket. Each set of conveyor belts includes a belt and a roller. This design can realize the back and forth movement of the storage rack, facilitate the rotation of the rotary loading mechanism, and avoid scratches and damages to other circuit boards.

[0011] Preferably, the rollers of the two groups of conveyor belts are arranged opposite to each other, and each opposite roller is connected by a connecting shaft. The connecting shaft is rotatably mounted on the bracket, and a rubber roller is fixed on the connecting shaft. The rubber roller contacts the bottom surface of the storage rack to provide support for the storage rack and reduce movement resistance to achieve smooth movement.

[0012] Furthermore, the slicing assembly also includes a push plate, the driving device is connected to the push plate, and the rigid connecting tube is arranged through the push plate so that different groups of slicing airbags move synchronously and the moving distance is the same. The rigid connecting tube is arranged obliquely downward relative to the push plate, and a spring is provided on the rigid connecting tube. The spring is arranged between the push plate and the slicing airbag. When the push plate drives the rigid connecting tube close to the circuit board, the spring is compressed synchronously. The rigid connecting tube is pushed by the thrust of the driving device and the elastic force of the spring to push the slicing airbag into the bottom of the vertically stacked circuit board. Slicing is achieved when the driving device drives the push plate to reciprocate.

[0013] Furthermore, the convex ring on the sliced ​​airbag includes a limiting convex ring and an end convex ring, and a recessed portion for accommodating a single-chip circuit board is provided between the end convex ring and the limiting convex ring. The end convex ring is configured to be thin-sheet-shaped. This design enables the sliced ​​airbag to have better flexibility after contacting the circuit board, and the thin-sheet-shaped end convex ring can slide across the bottom of the outermost circuit board and be inserted into the gap between the outermost circuit board and the adjacent circuit board. When the airbag is inflated, the end convex ring can further swell to separate the outermost circuit board from other circuit boards, thereby achieving the purpose of sliced ​​airbag.

[0014] Furthermore, the rotating assembly includes a rotating motor, a rotating shaft and a connecting block. The rotating motor is connected to the rotating shaft. The rotating shaft is mounted above the bracket. A connecting block is fixed on the rotating shaft. The support arm is vertically provided at the end of the connecting block. This design can make the support arm rotate around the rotating shaft, and the rotation process is more stable.

[0015] Furthermore, a first sensor is provided on the conveying mechanism and a second sensor is provided on the bracket. When the support arm is in a horizontal state, the first sensor is opposite to the connecting block, and when the support arm is in a vertical state, the second sensor is opposite to the support arm. This design enables the rotary loading mechanism to automatically switch between different states.

[0016] Preferably, the hook portion and the support arm are provided with protective cushions on the side in contact with the circuit board to prevent the circuit board from being damaged when being transferred from the storage rack to the support arm.

[0017] Furthermore, the conveying mechanism is a roller conveyor line, and the roller conveyor line is provided with a receiving groove at the end near the rotary loading mechanism. The receiving groove is opposite to the support arm and is used to form an avoidance space for the support arm. When the support arm rotates to a horizontal state, the support arm is completely embedded in the receiving groove, and the circuit board is separated from the support arm, contacts the roller conveyor line and is conveyed forward.

[0018] Preferably, a shaping component is movably provided on the roller conveyor line, and the shaping component is arranged close to the accommodating slot. The shaping component includes several symmetrically arranged cylinders, and the cylinders are arranged in the gap of the roller conveyor line and can move along the gap between the rollers. When the circuit board starts to be transported on the roller conveyor line, the shaping component moves inward from the edge along the gap. When the circuit board completely passes through the accommodating slot, the cylinder of the shaping component contacts the circuit board, thereby achieving fine-tuning of the position of the circuit board and facilitating subsequent processing.

[0019] Beneficial effects

[0020] One of the above technical solutions has the following advantages or beneficial effects:

[0021] 1) By setting up tooth-shaped segmented airbags, the segmented airbags have a certain degree of softness in the uninflated state, which can be bent through the bottom of the circuit board and inserted into the gap between adjacent circuit boards. When inflated, due to the expansion effect of air, they have a certain degree of hardness, which can expand the gap between the circuit boards. Through multiple reciprocating motions, the outermost circuit board can be completely separated.

[0022] 2) By setting up a rotatable support arm, the hook at the end of the support arm hooks the circuit board separated by the slicing mechanism when the support arm rotates, and the circuit board is placed against the support arm. When the support arm drives the circuit board to rotate to a horizontal state, it is automatically transferred to the conveying mechanism to complete automatic loading.

[0023] 3) Through the setting of the slicing mechanism and the rotary loading mechanism, the circuit boards can be put on line in vertical stacking and automatically slicing into the conveying mechanism, which has the characteristics of simple overall equipment structure, high degree of automation and high online efficiency.

DETAILED DESCRIPTION

[0030] The present invention will be further described in detail below with reference to the embodiments, but the embodiments of the present invention are not limited thereto.

[0031] like Figure 1 As shown, the utility model provides a stacked circuit board slicing and loading device, comprising a conveying mechanism 1, a bracket 2, a storage mechanism 3 provided on the bracket 2, a slicing mechanism 4 and a rotary loading mechanism 5;

[0032] like Figure 2 As shown, the storage mechanism 3 includes a storage rack 31 and a moving assembly 32. The storage rack 31 is used to stack circuit boards vertically. The storage rack 31 includes an L-shaped vertical plate 311 and a plurality of transverse rods 312. The moving assembly 32 includes a drive motor (not shown) and two sets of conveyor belts 321. The drive motor drives the two sets of conveyor belts 321 to move synchronously. The conveyor belts 321 are respectively arranged along the inner side of the bracket 2. Each set of conveyor belts 321 includes a belt 3211 and a roller 3212; the rollers 321 of the two sets of conveyor belts 321 are arranged in a vertical direction. 12 are arranged relative to each other, and each relative roller 3212 is connected by a connecting shaft 322. The connecting shaft 322 is rotatably installed on the bracket 2, and a rubber roller 323 is fixed on the connecting shaft 322. The transverse rod 312 at the edge of the storage rack 31 is placed on the conveyor belt 321, and the bottom surface of the vertical plate 311 of the storage rack 31 is in contact with the rubber roller 323 to provide support for the storage rack 31. When the conveyor belt 321 moves, the rubber roller 323 also rotates synchronously to reduce the movement resistance of the storage rack 31 and achieve smooth movement.

[0033] like Figure 3As shown, the slicing mechanism 4 is used to separate single-piece circuit boards from vertically stacked circuit boards; the slicing mechanism 4 includes a driving device 41 and a slicing assembly 42, the slicing assembly 42 includes a push plate 421, a rigid connecting tube 422 and a slicing airbag 423, the slicing airbag 423 is connected to the air source (not shown) through the rigid connecting tube 422, the driving device 41 is connected to the push plate 421, the rigid connecting tube 422 is arranged through the push plate 421, so that different groups of slicing airbags 423 move synchronously and have the same moving distance, the rigid connecting tube 422 is arranged tilted downward relative to the push plate 421, a spring 424 is sleeved on the rigid connecting tube 422, the spring 424 is arranged between the push plate 421 and the slicing airbag 423, the outer surface of the slicing airbag 423 is provided with a plurality of convex rings 4231 to form a tooth structure, which is used to separate single-piece circuit boards from vertically stacked circuit boards. The convex ring 4231 includes a limiting convex ring 4231-1 and an end convex ring 4231-3. A recessed portion 4231-2 for accommodating a single-chip circuit board is provided between the end convex ring 4231-3 and the limiting convex ring 4231-1. The end convex ring 4231-3 is in the shape of a thin sheet. When the push plate 421 drives the rigid connecting tube 422 close to the circuit board, the spring 424 is compressed synchronously, and the rigid connecting tube 422 makes the slice airbag 423 contact the circuit board. At the same time, under the action of the elastic force, the thin-sheet end convex ring 4231-3 can bend through the bottom of the outermost circuit board and insert into the gap between the outermost circuit board and the adjacent circuit board due to its flexibility. When the airbag is inflated, the end convex ring 4231-3 swells to further separate the outermost circuit board from the other circuit boards. The driving device 41 drives the push plate 421 to reciprocate several times to completely separate the outermost circuit board from the bottom of the other circuit boards. It should be understood that the aforementioned push plate 421 is not necessary, and the driving device 41 can be directly connected to the rigid connecting tube 422 and drive the rigid connecting tube 422 to perform horizontal reciprocating motion.

[0034] like Figure 4As shown, the rotary loading mechanism 5 can transform the circuit board from a vertical state to a horizontal state, thereby transferring the single circuit board from the storage mechanism 3 to the conveying mechanism 1.

When the support arm 52 is in a vertical state, the second sensor 21 is opposite to the support arm 52. By detecting the position of the support arm 52, the movement of the moving component 32 of the storage mechanism 3 and the driving device 41 of the slicing mechanism 4 are controlled in linkage.
