[0032] The stacking device and circuit board hot-melt production machine according to the embodiments of the present invention are described below with reference to the accompanying drawings.

[0033] Reference Figures 1 to 4The present invention aims to provide an embodiment of a stacking device, which may be a part of a circuit board hot melt production machine. Therefore, the present invention also aims to provide an embodiment of a circuit board hot melt production machine, which includes a stacking device.

[0034] Compared with the prior art, the stacking device of the present invention can conveniently stack the materials in an aligned manner, reducing repeated adjustments due to specification changes. At the same time, the hot melt production machine of the present invention can conveniently stack the materials in an aligned manner by applying the stacking device, reducing repeated adjustments due to specification changes, saving time and improving efficiency.

[0035] Reference Figure 1 , the present invention aims to provide an embodiment of a stacking device.

[0036] In this embodiment, the stacking device mainly includes a mounting frame 100, and the mounting frame 100 can be raised and lowered and translated to move and stack materials.

[0037] In some specific embodiments of the present invention, the mounting frame 100 can be connected to a gantry-type lifting and translation structure to meet the needs of transferring and stacking materials over a long stroke, reduce the space occupied around the circuit board hot melt production machine, and adapt to the special needs of circuit board hot melt production.

[0038] In some specific embodiments of the present invention, the mounting frame 100 may be allowed to translate in only a single direction, such as moving along the extension direction of the beam of the gantry structure, so as to reduce the overturning moment.

[0039] In some specific embodiments of the present invention, the lifting and translation of the mounting frame 100 can be achieved through the cooperation between the motor and the screw and sleeve, that is, the motor drives the screw to rotate, and the screw drives the sleeve, and the sleeve is fixed on the mounting frame 100. The sleeve produces linear motion due to limited rotation, so that the mounting frame 100 is lifted or translated.

[0040] In some specific embodiments of the present invention, the lifting and translation of the mounting frame 100 can be achieved through the cooperation of a motor and a gear rack, that is, the motor drives the gear to rotate, the gear meshes with the rack, the gear drives the rack to move, the rack is installed on the mounting frame 100, and the rack moves together with the mounting frame 100 to complete the lifting or translation.

[0041] To facilitate the transfer of products to be stacked, the present embodiment further includes a material taking mechanism, which is mounted on the mounting frame 100. Thus, driven by the mounting frame 100, the material taking mechanism can be in a material taking position and a material placing position, which facilitates taking, placing and stacking.

[0042] Specifically, the material taking mechanism includes a rotating frame 110 , a material suction assembly 120 and a material pressing assembly 130 disposed on the rotating frame 110 , and the rotating frame 110 is connected to the mounting frame 100 .

[0043] It is easy to understand that, by providing the suction assembly 120, this embodiment can absorb large flat sheet products by negative pressure adsorption, avoid damaging the products by clamping and the like, and meet the production needs of circuit boards.

[0044] The material pressing component 130 is provided, and the material pressing component 130 can compact the products to be stacked before taking the materials, especially before and after stacking, to meet the stacking requirements. At the same time, it can prevent the suction component 120 from lifting the products when it is removed after completing the stacking, thereby ensuring the stacking quality.

[0045] The rotating frame 110 is used to drive the products to be stacked to rotate horizontally for alignment, so as to overcome the angle deviation between the products stacked front and back.

[0046] As for the position deviation of the front-to-back stacked products, the mounting frame 100 can increase or decrease the original movement distance without adding additional structures, thus simplifying the equipment.

[0047] In order to confirm the position deviation, angle deviation and specifications of the product, the present embodiment is also provided with a detection mechanism, which is installed on the mounting frame 100. The detection mechanism includes a CCD detector 140 and a translation assembly 150 for driving the CCD detector 140 to translate. The translation assembly 150 is connected to the mounting frame 100.

[0048] It is easy to understand that when in use, the translation assembly 150 first drives the CCD detector 140 to translate to find the marking point of the product. Then, the CCD detector 140 detects and confirms the position of the marking point, and obtains the position deviation, angle deviation and product specifications by comparing with the reference data, thereby correcting the stacking program, such as changing the origin and direction of the coordinate system, and then adjusting the action of the material picking mechanism and the mounting frame 100 so that the products can be stacked in an aligned manner to meet the stacking needs.

[0049] In summary, in this embodiment, the mounting frame 100 is provided so that the mounting frame 100 can be raised, lowered and translated. Therefore, the products to be stacked can be transferred and stacked into the circuit board hot melt production machine to meet the hot melt production needs.

[0050] In this embodiment, a material picking mechanism is provided, and the material picking mechanism includes a material suction component 120 and a material pressing component 130. Therefore, on the one hand, the material suction component 120 can be used to facilitate the picking up of the products to be stacked, and on the other hand, the material pressing component 130 can be used to press and fix the products to be stacked, so as to prevent the products to be stacked from being randomly moved when the material suction component 120 is released, thereby affecting the stacking quality.

[0051] In this embodiment, a material taking mechanism is provided so that the material taking assembly includes a rotating frame 110. Therefore, when the orientation of the products to be stacked does not meet the requirements, the rotating frame 110 can be rotated so that the stacked products are aligned up and down.

[0052] In this embodiment, a detection mechanism is provided, and the detection mechanism includes a CCD detector 140. Therefore, the marking points of the products to be stacked can be determined by image detection without relying on mechanical positioning, which helps to reduce repeated adjustments caused by changes in specifications.

[0053] In this embodiment, the detection mechanism is provided so that the detection mechanism includes a translation component 150. Therefore, the position of the CCD detector 140 can be adjusted by the translation component 150, so as to facilitate the detection of marking points of products to be stacked of different specifications and be easy to use.

[0054] At the same time, the detection mechanism includes a translation assembly 150, which increases the movable distance of the CCD detector 140 in the horizontal direction and facilitates the inspection of products of different specifications.

[0055] At the same time, the detection mechanism includes a translation component 150, so that the CCD detector 140 moves mostly in the horizontal direction, does not generate any lifting movement relative to the suction component 120, does not affect the occupied space, and is convenient for setting the suction component 120 larger, so that the suction component 120 can absorb circuit boards with a wide range of specifications, making the stacking device easy to use.

[0056] Meanwhile, the detection mechanism includes a translation assembly 150 , and the lifting and lowering of the CCD detector 140 depends on the lifting and lowering of the mounting frame 100 , so as to avoid collision damage caused by the CCD detector 140 being lifted and lowered alone.

[0057] In some specific embodiments of the present invention, the suction assembly 120 may include a suction plate 160 , the CCD detector 140 is located above the suction plate 160 , and the suction plate 160 has a notch 170 , which is used to allow the CCD detector 140 to detect marking points of the products to be stacked.

[0058] It is easy to understand that in this embodiment, the notch 170 is provided to facilitate the CCD detector 140 to identify the marking point, so as to adapt to the situation where the product specification is smaller than the suction plate 160.

[0059] In some specific embodiments of the present invention, the slot 170 can have a length direction, and the length direction of the slot 170 is set along the translation direction of the CCD detector 140 relative to the mounting frame 100, which not only meets the detection needs, but also makes the physical area of ​​the suction plate 160 larger, avoiding affecting the suction capacity of the suction plate 160.

[0060] In some specific embodiments of the present invention, the number of CCD detectors 140 can be two, and the number of translation components 150 can be two groups accordingly, so that the two CCD detectors 140 can be close to or far away from each other.

[0061] It is easy to understand that, by providing two CCD detectors 140 , this embodiment can be applicable to a situation with two relative marking points, and can also be applicable to a situation where the points are placed upside down.

[0062] Furthermore, the two CCD detectors 140 can be close to or far away from each other, and can also be applied to actual situations where the placement conditions of the circuit boards are diverse and non-uniform, such as center placement, placement on a certain side, etc.

[0063] In some specific embodiments of the present invention, the rotating frame 110 can have a hollow cavity, and the mounting frame 100 can have a first mounting portion 180, which is located in the hollow cavity, the top of the first mounting portion 180 is connected to the rotating frame 110, and the bottom of the first mounting portion 180 is provided with a detection mechanism.

[0064] It is easy to understand that this embodiment can solve the layout problem of connecting the mounting frame 100 to the material taking mechanism and the detection mechanism at the same time by making the rotating frame 110 have a hollow cavity, reduce the space occupied by the stacking device in the horizontal direction, and facilitate material taking and detection.

[0065] At the same time, in the up and down directions, the stacking device structure is made more compact, and the CCD detector 140 can be closer to the product to be detected, thereby improving the detection accuracy, and further aligning and stacking the products with higher accuracy.

[0066] In some specific embodiments of the present invention, the rotating frame 110 can include an upper mounting plate 190 and a plurality of side brackets, the upper mounting plate 190 and the plurality of side brackets cooperate to form a hollow cavity, the plurality of side brackets include a first side bracket 200 and a second side bracket 210, the bottom of the first side bracket 200 is used to connect to the suction plate 160, and the bottom of the second side bracket 210 is used to connect to the pressing assembly 130.

[0067] It is easy to understand that, in this embodiment, by providing the upper mounting plate 190 and the side bracket, a hollow cavity is conveniently formed, which not only meets the layout requirements, but also simplifies the structure, reduces the manufacturing cost, and has low assembly difficulty.

[0068] In some specific embodiments of the present invention, the first side bracket 200 may be L-shaped, U-shaped or C-shaped, and the internal space of the first side bracket 200 is used to accommodate the translation assembly 150 to pass through.

[0069] It is easy to understand that, in this embodiment, by making the first side bracket 200 have a specific shape, it can avoid the translation assembly 150 of the detection mechanism without affecting the layout and stroke of the translation assembly 150 , and it is convenient to connect the suction plate 160 to meet the need of fixing the suction plate 160 .

[0070] In some specific embodiments of the present invention, the number of the second side brackets 210 can be two, the two second side brackets 210 are located on two opposite sides of the suction plate 160, and a crossbeam 220 is provided between the two second side brackets 210, and the crossbeam 220 connects the suction plate 160.

[0071] It is easy to understand that in this embodiment, by setting the second side bracket 210, a cross beam 220 is connected between the second side brackets 210, so that the middle part of the suction plate 160 can be connected and fixed, so as to avoid the middle part of the suction plate 160 collapsing downward due to gravity and the shape characteristics of the suction plate 160 itself, avoid affecting the flatness of the suction plate 160, and avoid affecting the suction effect.

[0072] In some specific embodiments of the present invention, the pressing assembly 130 may include a pressing block and a cylinder for driving the pressing block to rise and fall, and the cylinder is installed on the second side bracket 210, so that the pressing assembly 130 can react quickly and efficiently.

[0073] In some specific embodiments of the present invention, the mounting frame 100 can be provided with a power mechanism for driving the rotating frame 110 to rotate. The power mechanism includes a plurality of power components 230 arranged in a ring. The power components 230 include a transverse member 240 connected to the mounting frame 100 and a longitudinal member 250 connected to the transverse member 240. The longitudinal member 250 is rotatably connected to the rotating frame 110. The mounting frame 100 is provided with a screw sleeve transmission structure 260 and a motor for driving the transverse member 240 to move.

[0074] It is easy to understand that the present embodiment sets a plurality of power components 230 and makes the power components 230 have the above-mentioned arrangement, thereby achieving rotational connection and avoiding the use of common shafts and holes, which helps to increase the supporting strength. At the same time, there is no need to set shafts and holes with larger diameters, which reduces the occupied space and facilitates the layout.

[0075] In this embodiment, there are four sets of power components 230, each set of power components 230 causes the rotating frame 110 to generate circular tangential movement. The four sets of power components 230 cooperate to cause the rotating frame 110 to generate four sections of circular tangential movement, and the centers of the four sections of circular tangential movement coincide, so that the rotating frame 110 rotates.

[0076] The longitudinal moving member 250 is rotatably connected to the rotating frame 110 , which can meet the connection requirement when the rotating frame 110 rotates.

[0077] At the same time, since the incoming direction of the product is basically determined, the rotation angle of the rotating frame 110 is very small. Therefore, although the length and stroke of the transverse moving member 240 and the longitudinal moving member 250 are short, they can still meet the use requirements. In addition, the four power components 230 In some specific embodiments of the present invention, the mounting frame 100 may be further provided with a compensation spring 270 connected to the transverse member 240 .

[0078] It is easy to understand that, in this embodiment, by providing the compensation spring 270, the screw and the sleeve can maintain contact in the axial direction, thereby reducing transmission gaps caused by manufacturing misconceptions, allowing the four power components 230 to work synchronously and improving transmission reliability.
