Technical Field

[0001] This utility model belongs to the field of circuit board manufacturing and relates to circuit board conveying technology, specifically a conveying device for multilayer circuit boards. Background Technology

[0002] Multilayer circuit boards are circuit boards made up of multiple conductive layers and insulating layers stacked alternately. The production process of multilayer circuit boards requires multiple steps, and the circuit boards are generally moved to different workstations through a conveyor device.

[0003] The reference patent is titled: "A Circuit Board Printing Conveying Device (Patent Publication No.: CN221439421U)". The device uses a conveying mechanism to transport a support plate. The support plate is supported and constrained by positioning pins. The conveying mechanism transports the circuit board to a designated position. The height of the conveying device is adjusted by a lifting device, which allows the conveying mechanisms to operate alternately, improving the conveying efficiency and avoiding relative movement between the circuit board and the support plate that could cause wear on the circuit board.

[0004] However, the following problems exist when implementing the above technical solutions: In the above device, the support plate limits the position of the circuit board by positioning pins. Therefore, when fixing or disassembling the circuit board to the support plate, the positioning pins need to be manually removed and the circuit board placed or taken out. This conveying device requires multiple operators to work continuously to convey the circuit board, and there are relatively many manual operation procedures. Moreover, the long-term single operation by the operators will cause fatigue in the muscle groups of the operators' hands, shoulders and back. The accumulation of fatigue may lead to sluggishness, thereby affecting the overall operation time.

[0005] Therefore, this utility model proposes a conveying device for multilayer circuit boards. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a multi-layer circuit board conveying device. This device solves the problem that when conveying circuit boards, operators are required to assist in placing the circuit boards and positioning pins, but prolonged repetitive operation by the operators inevitably leads to fatigue, affecting the conveying time.

[0007] To achieve the above objectives, a conveying device for a multilayer circuit board is provided according to an embodiment of the first aspect of this utility model, comprising a conveying table and two conveying blocks, wherein each conveying block is slidably connected to the interior of the conveying table, and each conveying block is provided with a fixing mechanism, the fixing mechanism comprising:

[0008] The conveyor block has an insertion slot and two through slots. The insertion slot is formed on the surface of the conveyor block, and the depth of the insertion slot near the loading end is less than the depth of the insertion slot near the unloading end. The through slots are symmetrically arranged and communicate with the insertion slot.

[0009] The device includes a limiting block, a connecting rod, and a limiting rod. The connecting rod is rotatably connected to the inside of the conveying block, and the limiting block and the limiting rod are slidably connected to the surface of the connecting rod. The limiting block and the limiting rod are both located inside the insertion groove, and a return spring is fixedly connected between the limiting block and the connecting rod.

[0010] A contact rod is rotatably connected to the surface of the limiting block, and an arc-shaped groove is formed on the surface of the contact rod.

[0011] A driving block is internally slidably connected to a conveying block, and a tension spring is fixedly connected between the driving block and the conveying block.

[0012] Optionally, a conveyor belt is slidably connected inside the conveyor platform, and multiple transfer blocks are fixedly connected to the surface of the conveyor belt, with some of the transfer blocks' surfaces fixedly connected to a single conveyor block.

[0013] Optionally, some of the transfer block surfaces are slidably connected to a single conveyor block, and the transfer block surface is fixedly connected to the conveyor block surface such that the height of the transfer block is greater than the height of the other transfer blocks.

[0014] Optionally, a sliding shaft is fixedly connected to the surface of the conveying block that slides with the transfer block, and a sliding groove is provided on the surface of the conveying table, with the sliding shaft adapted to the sliding groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: Insertion grooves and through grooves of varying depths are formed on the surface of the conveyor block for transporting multi-layer circuit boards. These grooves guide the multi-layer circuit boards to a specific position on the conveyor block, where they contact the contact rod. The contact rod and limiting rod ensure that the multi-layer circuit boards do not detach from the conveyor block during its movement. Furthermore, the contact rod can rotate, allowing the multi-layer circuit board to slide directly along the conveyor block and detach from it for unloading when its surface is parallel to the through groove. A sliding drive block is also provided inside the conveyor block; pulling the drive block changes the position of the conveyor block. By pulling, the multi-layer circuit board contacts the through groove, allowing it to be removed from the other two sides of the conveyor block.

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

[0029] like Figure 1-5 As shown, the conveying device for a multilayer circuit board includes a conveying platform 1 and two conveying blocks 2. The conveying blocks 2 are slidably connected to the inside of the conveying platform 1. Each conveying block 2 is equipped with a fixing mechanism, which includes:

[0030] An insertion groove 31 is formed on the surface of the conveying block 2. The depth of the insertion groove 31 near the loading end is less than the depth near the unloading end. Two through grooves 32 are formed on the surface of the conveying block 2. The through grooves 32 are symmetrically arranged along the center line of the conveying block 2 and communicate with the insertion groove 31. The depth of the through groove 32 near the insertion groove 31 is greater than the depth away from the insertion groove 31. The length of the insertion groove 31 is less than the length of the conveying block 2. A cross-shaped groove is formed on the surface of the conveying block 2. The groove near the center line of the conveying block 2 is deeper, and the depth near the unloading end is greater than the depth near the loading end. When the multilayer circuit board arrives at the position of the conveying block 2 from the previous process, it can slide directly into the conveying block 2 through the insertion groove 31 and slide completely into the surface of the conveying block 2 under the action of the insertion groove 31, ensuring the adhesion between the multilayer circuit board and the conveying block 2.

[0031] The system comprises a limiting block 33, a connecting rod 34, and a limiting rod 35. The connecting rod 34 is rotatably connected to the inside of the conveying block 2. A through-connecting groove is formed on the surface of the connecting rod 34. A through rod is fixedly connected inside the conveying block 2. The connecting groove is adapted to the through rod. A balance spring is fixedly connected between the connecting rod 34 and the conveying block 2. The limiting block 33 and the limiting rod 35 are slidably connected to the surface of the connecting rod 34. The limiting block 33, the connecting rod 34, and the limiting rod 35 all extend along the conveying direction of the multilayer circuit board, and the limiting block 33 and the limiting rod 35 are spaced apart in this direction. A return spring is fixedly connected between the limiting block 33 and the connecting rod 34. The distance between the limiting block 33 and the limiting rod 35 is greater than the length of the multilayer circuit board. The limiting block 33 and the limiting rod 35 can limit the position of the multilayer circuit board after it is conveyed to the surface of the conveying block 2, preventing the multilayer circuit board from sliding off the conveying block 2 due to inertia during the sliding process.

[0032] A contact rod 37 is rotatably connected to the surface of a limiting block 33. An arc-shaped groove 38 is formed on the surface of the contact rod 37, and the opening direction of the arc-shaped groove 38 is opposite to the conveying direction of the multilayer circuit board. A rotating spring is fixedly connected between the contact rod 37 and the conveying block 2. With the contact rod 37, under the action of the inclined insertion groove 31, the multilayer circuit board will be blocked when it slides to the position of the contact rod 37. Under the action of the arc-shaped groove 38, the rotation direction will cause the contact rod 37 to press down, causing the limiting block 33 to slide on one side of the connecting rod 34. Then the limiting rod 35 will slide up. The limiting block 33 and the limiting rod 35 restrict the position of the multilayer circuit board.

[0033] A drive block 39 is slidably connected to the inside of the conveying block 2. The drive block 39 is located between the limiting block 33 and the limiting rod 35, and is a certain distance away from the connecting rod 34. The surface of the drive block 39 has multiple protruding pillars. A tension spring 36 is fixedly connected between the drive block 39 and the conveying block 2. The drive block 39 has a rough surface and will contact the multi-layer circuit board. The drive block 39 can slide, thereby pulling the drive block 39. Through friction, the multi-layer circuit board can slide inside the conveying block 2, and then the multi-layer circuit board can be taken out from the through slot 32 direction on the conveying block 2.

[0034] In practical application, the conveying device for this multilayer circuit board has insertion grooves 31 and through grooves 32 with varying depths on the surface of the conveying block 2. These grooves guide the multilayer circuit board to a specific position on the conveying block 2, where it contacts the contact rod 37. The contact rod 37 and a limiting rod 35 ensure that the multilayer circuit board does not detach from the conveying block 2 during its movement. Furthermore, the contact rod 37 is rotatable, allowing the multilayer circuit board to slide directly along the conveying block 2 when its surface is parallel to the through groove 32. The material is unloaded by detachment, and a sliding drive block 39 is set inside the conveyor block 2. Pulling the drive block 39 can change the position of the conveyor block 2. By pulling, the multi-layer circuit board is brought into contact with the through groove 32. The multi-layer circuit board can be taken out from the other two sides of the conveyor block 2. The position of the multi-layer circuit board during the conveying process can be fixed by the contact rod 37 and the limiting rod 35. The multi-layer circuit board can be taken out from different positions by rotating the contact rod 37 or sliding the drive block 39. It is suitable for conveying multi-layer circuit boards between multiple processes. During the conveying process, the operation is only required when taking them out, making the steps simpler.

[0035] In some specific implementations, a conveyor belt 41 is slidably connected inside the conveyor table 1, and a plurality of transfer blocks 42 are fixedly connected to the surface of the conveyor belt 41. Some of the surfaces of the transfer blocks 42 are fixedly connected to a single conveyor block 2, and some of the surfaces of the transfer blocks 42 are slidably connected to a single conveyor block 2. The height of the transfer block 42 fixedly connected to the surface of the conveyor block 2 is greater than the height of the other transfer blocks 42.

[0036] In a further embodiment, the two conveying blocks 2 are fixed to the surface of the conveyor belt 41 that slides in different directions, and the two conveying blocks 2 are symmetrically arranged along the center line of the conveyor table 1.

[0037] In a further embodiment, a sliding shaft 43 is fixedly connected to the surface of the conveying block 2 that slides with the transfer block 42, and a sliding groove 44 is provided on the surface of the conveying table 1, and the sliding shaft 43 is adapted to the sliding groove 44;

[0038] In a further embodiment, the sliding groove 44 includes a V-shaped groove and two horizontal grooves, one end of the two horizontal grooves passing through the two vertices of the V-shaped groove, and the two horizontal grooves are not connected.

[0039] In some specific implementations, the contact rod 37 has two spiral grooves 51 inside, the two spiral grooves 51 rotate in opposite directions, and an elastic block 52 is fixedly connected at the intersection of the two spiral grooves 51. An operating rod 53 is slidably connected inside the conveying block 2, and two operating posts 54 are fixedly connected to the surface of the operating rod 53. The horizontal distance between the two operating posts 54 is equal to the width of the contact rod 37, and the operating posts 54 are adapted to the spiral grooves 51.

[0040] The working principle of this utility model:

[0041] The multilayer circuit board slides into the conveyor block 2 from the loading end. After the multilayer circuit board slides to contact the contact rod 37, it stops sliding under the action of the contact rod 37. Due to the pressure of the multilayer circuit board, the contact rod 37 moves downward. The downward movement of the contact rod 37 causes the limiting block 33 to move downward, which in turn causes the connecting rod 34 to rotate, driving the limiting rod 35 to move upward. The limiting rod 35 and the contact rod 37 restrict the position of the multilayer circuit board. Then, the conveyor belt 41 is driven to slide. The sliding of the conveyor belt 41 causes the transfer block 42 to slide. The sliding of the transfer block 42 causes the conveyor block 2 to slide. When the conveyor block 2 carrying the multilayer circuit board slides, the other conveyor block 2 also slides. 2. Slide to the V-groove position, causing the conveyor block 2 to move down, resulting in a height difference between the two conveyor blocks 2. Then, the two conveyor blocks 2 slide towards each other. When the empty conveyor block 2 slides to the loading end, the conveyor block 2 slides to the unloading end. Pull the operating rod 53. The sliding of the operating rod 53 causes the operating column 54 to slide, and the contact rod 37 rotates. The multi-layer circuit board slides out from the other end of the conveyor block 2. Pull the driving block 39. The sliding of the driving block 39 causes the multi-layer circuit board to slide towards the through groove 32 of the conveyor block 2. The multi-layer circuit board can be taken out from both sides of the conveyor block 2. Release the driving block 39. The driving block 39 resets under the action of the pulling spring 36.

[0042] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
