Description

Technical Field

[0001] The invention relates to the field of circuit board production equipment, and in particular to a prepreg separation device. Background Art

[0002] The structure of the circuit board is copper foil-inner layer board-copper foil. During the production process, a prepreg needs to be placed between the copper foil and the inner layer board to facilitate subsequent processing steps, which requires the prepreg to be loaded.

[0003] The existing prepregs are transported and stored in stacks. Therefore, when loading, a single prepreg needs to be taken out separately from the whole stack of prepregs. Due to the characteristics of the prepregs, the stacked prepregs are often stuck together, resulting in the problem that two or more stuck prepregs are sometimes taken out at the same time when taking out the materials, which affects the normal production.

[0004] Therefore, it is necessary to propose improvements for the problems existing in the prior art. Summary of the invention

[0005] The object of the present invention is to provide a prepreg separating device, aiming to solve the problem in the prior art that two or more prepregs that are stuck together may be taken out at the same time when the prepregs are taken out.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a semi-cured sheet separation device, including a material storage frame, which also includes a pick-up and place mechanism and an air suction nozzle and a pressure rod arranged on the material storage frame; the pick-up and place mechanism is suitable for moving to a suction position located above the material storage frame and sucking the semi-cured sheet from the material storage frame, and the pick-up and place mechanism is provided with a flanging mechanism, and the flanging mechanism is used to flanging the edge portion of the sucked semi-cured sheet upwards; the air suction nozzle and the pressure rod are both located below the suction position, and the air suction nozzle is suitable for sucking air from the bottom to the flanging edge portion of the semi-cured sheet to separate the adhered semi-cured sheet, and the pressure rod is suitable for pressing down the separated semi-cured sheet located below.

[0008] Furthermore, the pick-and-place mechanism also includes a first bidirectional driving mechanism for driving the mounting frame to move horizontally and vertically.

[0009] Furthermore, the suction nozzle is installed on the material storage frame through a telescopic mechanism, and the telescopic mechanism is arranged at an angle, so that the suction nozzle can move to an extended position and a retracted position; when the suction nozzle is in the extended position, the suction nozzle is close to the semi-cured sheet; when the suction nozzle is in the retracted position, the suction nozzle is away from the semi-cured sheet and can avoid the semi-cured sheet.

[0010] Furthermore, the pressure rod is installed on the material storage frame through a second bidirectional driving mechanism, and the second bidirectional driving mechanism is used to drive the pressure rod to move longitudinally and vertically, and the pressure rod can move to an extended position and a retracted position; when the pressure rod is in the extended position, the pressure rod can press down the semi-cured sheet; when the pressure rod is in the retracted position, the pressure rod can avoid the semi-cured sheet.

[0029] The present invention is described in detail below in conjunction with specific embodiments.

[0030] In the present invention, when directional words appear, the directional words are for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present invention. In the present invention, unless otherwise specified and limited, when terms such as "set on", "connected" and "connected" appear, these terms should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or it can be connected through an intermediate medium, or it can be that the two elements are internally connected. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In the present invention, unless otherwise specified and limited, when the first feature appears "on" or "under" the second feature, it can include the first feature directly contacting the second feature, and it can also include the first feature not directly contacting the second feature but contacting through another feature between them. Moreover, when the first feature is "above" the second feature, it includes the first feature directly above and diagonally above the second feature, or it simply means that the height of the first feature is higher than the height of the second feature; when the first feature is "below" the second feature, it includes the first feature directly below and diagonally below the second feature, or it simply means that the height of the first feature is lower than the height of the second feature.

[0031] The present invention provides a prepreg separation device, such as Figures 1 to 6 As shown, it includes a material storage frame 1, which also includes a pick-up and place mechanism 2 and a suction nozzle 3 and a pressure rod 4 arranged on the material storage frame 1; the pick-up and place mechanism 2 is suitable for moving to the suction position located above the material storage frame 1 and sucking the semi-cured sheet from the material storage frame 1, and the pick-up and place mechanism 2 is provided with a flanging mechanism, which is used to flanging the edge portion of the sucked semi-cured sheet upwards; the suction nozzle 3 and the pressure rod 4 are both located below the suction position, and the suction nozzle 3 is suitable for sucking air from the bottom to the flanging edge portion of the semi-cured sheet to separate the adhered semi-cured sheet, and the pressure rod 4 is suitable for pressing down the separated semi-cured sheet located below.

[0032] Based on the above structure, when the prepreg separation device is used, the pick-and-place mechanism 2 sucks the prepreg, and the pick-and-place mechanism 2 turns the edge of the prepreg to make it easier to separate the prepregs that are stuck together. Then, the suction nozzle 3 sucks air toward the edge after the turning. Through the suction force, the pick-and-place mechanism 2 sucks the top prepreg, and the suction nozzle 3 sucks the bottom prepreg downward, so that a gap is formed between the bottom prepreg and the top prepreg. The pressure rod 4 is inserted into the gap and presses the bottom prepreg downward, so that the top prepreg is separated from the bottom prepreg. The pick-and-place mechanism 2 moves away to allow a single piece of prepreg to be taken out separately from the whole stack of prepregs.

[0033] In this embodiment, the pick-and-place mechanism 2 includes a mounting frame 21, a fixed frame 22, a flanging frame 23, a flanging driving mechanism 24, and a plurality of suction cups 25. The fixed frame 22 is fixed to the mounting frame 21, the flanging frame 23 is rotatably connected to the fixed frame 22, a plurality of suction cups 25 are distributed and installed on the fixed frame 22 and the flanging frame 23, and the flanging driving mechanism 24 is connected between the fixed frame 22 and the flanging frame 23 and drives the flanging frame 23 to rotate relative to the fixed frame 22. The above structure is used to suck up the prepreg and flanging the prepreg. The flanging driving mechanism 24 preferably adopts a telescopic cylinder, such as a pneumatic cylinder or a hydraulic cylinder, and drives the flanging frame 23 to rotate relative to the fixed frame 22 by the telescopic cylinder.

[0034] In this embodiment, the pick-and-place mechanism 2 further includes a first bidirectional driving mechanism 26 for driving the mounting frame 21 to move horizontally and vertically. Through the above structure, the pick-and-place mechanism 2 can be translated and lifted. The translation is to send the prepreg to the next station, and the lifting is to lift the prepreg after sucking it to leave the sucking position.

[0035] In this embodiment, the suction nozzle 3 is installed on the material storage frame 1 through a telescopic mechanism 31. The telescopic mechanism 31 is tilted, and the suction nozzle 3 can move to an extended position and a retracted position; when the suction nozzle 3 is in the extended position, the suction nozzle 3 is close to the prepreg; when the suction nozzle 3 is in the retracted position, the suction nozzle 3 is away from the prepreg and can avoid the prepreg. Through the above structure, it is possible to prevent the pick-and-place mechanism 2 from hitting the suction nozzle 3 when sucking up the prepreg, and when the suction nozzle 3 is needed to suck the prepreg, the suction nozzle 3 is extended close to the prepreg.

[0036] In this embodiment, the pressure rod 4 is installed on the material storage frame 1 through the second bidirectional driving mechanism 41. The second bidirectional driving mechanism 41 is used to drive the pressure rod 4 to move longitudinally and vertically. The pressure rod 4 can move to the extended position and the retracted position; when the pressure rod 4 is in the extended position, the pressure rod 4 can press down the semi-cured sheet; when the pressure rod 4 is in the retracted position, the pressure rod 4 can avoid the semi-cured sheet. Through the above structure, when the pick-up and place mechanism 2 sucks up the semi-cured sheet, it can prevent the pressure rod 4 from hindering the semi-cured sheet from rising, and when it is necessary to press down the semi-cured sheet, the pressure rod 4 can move to the top of the semi-cured sheet located below and then extend into it. In addition, the pressure rod 4 is set to be able to move vertically. After the pressure rod 4 is raised, it enters the gap between the semi-cured sheets to form a high success rate. After entering the gap, the pressure rod 4 drops and presses down the semi-cured sheet.

[0037] In this embodiment, the material storage frame 1 is provided with a static eliminator 5. The provision of the static eliminator 5 can reduce the static effect between the prepregs, making it easier to separate the prepregs.

[0038] In this embodiment, the prepreg separation device further includes a thickness detector 6, which is installed on the storage frame 1 through a longitudinal movement mechanism 61. The thickness detector 6 can move to an extended position and a retracted position; when the thickness detector 6 is in the extended position, the thickness detector 6 can detect the thickness of the prepreg; when the thickness detector 6 is in the retracted position, the thickness detector 6 can avoid the prepreg. In special cases, the pick-up and place mechanism 2 may suck up three or more prepregs at the same time, and the suction nozzle 3 only separates the bottom layer of prepregs, resulting in the pick-up and place mechanism 2 still picking up two or more prepregs. In order to avoid the above situation, a thickness detector 6 is provided. The thickness detector extends at an appropriate time to detect the thickness of the prepreg picked up by the pick-up and place mechanism 2. When the detected thickness is not only a single piece, the suction nozzle 3 and the pressure rod 4 act again until only a single piece is left, and retract when detection is not needed to avoid the prepreg.

[0039] In this embodiment, the material storage frame 1 includes a frame 11, a belt (not shown in the frame 11, the belt is driven by the motor to move forward and reverse), a first material tray 12 and a second material tray 13, the belt is rotatably connected to the frame 11, the first material tray 12 is connected to the upper part of the belt and is driven to slide by the belt, and the second material tray 13 is connected to the lower part of the belt and is driven to slide by the belt. By setting two material trays, efficiency is improved. When one of the material trays moves to the bottom of the suction position, the other material tray moves to the position where the worker loads the material. The worker loads the material without hindering the work of the pick-up and place mechanism 2. The driving belt is continuously reversed forward and reversed, so that the two material trays can be moved alternately to avoid shutdown. In this embodiment, the second material tray 13 is connected to the lower part of the belt by means of a slide plate 14, and a lifting mechanism 15 is provided between the second material tray 13 and the slide plate 14. Based on the above structure. When the second material tray 13 moves to the bottom of the suction position, the height of the second material tray 13 is increased by the lifting of the lifting mechanism 15, so that the pick-up and place mechanism 2 can take the prepreg at the same height.

[0040] It should be noted that the specific implementation forms of the lifting mechanism 15, the first bidirectional drive mechanism 26, the second bidirectional drive mechanism 41 and the longitudinal motion mechanism 61 mentioned in the present invention can be diverse. For example, linear modules, pneumatic or hydraulic telescopic cylinders, etc. and combinations of the above devices or mechanisms can be used to achieve the function of the driving movement recorded in the present invention. The above devices or mechanisms and similar replacements in the mechanical field, as long as they can achieve the function of the driving movement recorded in the present invention, also fall within the protection scope of the present invention.

[0041] In summary, the prepreg separating device can avoid taking up two or more prepregs that are stuck together at the same time, thereby ensuring normal production.

[0042] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
