[0039] The following description, in conjunction with the accompanying drawings, describes a material stacking device and a circuit board hot-melt production machine according to embodiments of the present invention.

[0040] Reference Figures 1 to 4The present invention aims to provide an embodiment of a stacking device, which may be 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.

[0041] Compared with existing technologies, the material stacking device of this invention can easily stack materials in an aligned manner, reducing repeated adjustments caused by changes in specifications. Meanwhile, the circuit board hot-melt production machine of this invention, by applying the above-mentioned material stacking device, can easily stack materials in an aligned manner, reducing repeated adjustments caused by changes in specifications, saving time and improving efficiency.

[0042] Reference Figure 1 The present invention aims to provide an embodiment of a material stacking device.

[0043] In this embodiment, the material stacking device mainly includes a mounting frame 100, which can be raised, lowered, and moved horizontally to move and stack materials.

[0044] In some specific embodiments of this utility model, the mounting bracket 100 can be connected to a gantry-type lifting and translation structure to meet the needs of large-stroke material transfer and material stacking, reduce the space occupied around the circuit board hot melt production machine, and adapt to the special needs of circuit board hot melt production.

[0045] In some specific embodiments of this utility model, the mounting bracket 100 can be made to translate in only one direction, such as moving along the extension direction of the beam of the gantry structure, in order to reduce the overturning moment.

[0046] In some specific embodiments of this utility model, the lifting and translation of the mounting bracket 100 can be achieved by the cooperation of a motor and a screw sleeve. That is, the motor drives the screw to rotate, the screw drives the sleeve, and the sleeve is fixed on the mounting bracket 100. The sleeve generates linear motion due to the restricted rotation, so that the mounting bracket 100 can be lifted or translated.

[0047] In some specific embodiments of this utility model, the lifting and translating of the mounting bracket 100 can be achieved by 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 mounted on the mounting bracket 100, and the rack moves together with the mounting bracket 100 to complete the lifting or translating.

[0048] To facilitate the transfer of products to be stacked, this embodiment also includes a material picking mechanism, which is installed on the mounting frame 100. Therefore, driven by the mounting frame 100, the material picking mechanism can be in the material picking position and the material placing position, which facilitates picking, placing and stacking.

[0049] Specifically, the material handling mechanism includes a rotating frame 110, a material suction component 120 and a material pressing component 130 disposed on the rotating frame 110, and the rotating frame 110 is connected to the mounting frame 100.

[0050] It is easy to understand that by setting up the suction component 120 in this embodiment, the thin sheet product of the large flat plate can be picked up by negative pressure adsorption, avoiding damage to the product by clamping or other methods, and meeting the production needs of the circuit board.

[0051] The pressing component 130 is provided so that the products to be stacked can be compacted before material is picked up, especially before and after stacking, to meet the stacking requirements. At the same time, it prevents the products from being lifted up when the suction component 120 completes stacking and moves away, thus ensuring the stacking quality.

[0052] The rotating frame 110 is used to drive the products to be stacked to rotate horizontally to align them, so as to overcome the angular deviation between the products stacked in front and behind.

[0053] As for the positional deviation of products stacked one after the other, the mounting bracket 100 can increase or decrease the original movement distance without adding any additional structure, thus simplifying the equipment.

[0054] To confirm the product's positional deviation, angular deviation, and product specifications, this embodiment also includes a detection mechanism. The detection mechanism is mounted on the mounting frame 100 and includes a CCD detector 140 and a translation component 150 for moving the CCD detector 140. The translation component 150 is connected to the mounting frame 100.

[0055] It is easy to understand that during use, the translation component 150 first drives the CCD detector 140 to translate and 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. In this way, the stacking procedure is corrected, such as changing the origin and direction of the coordinate system. Furthermore, the actions of the picking mechanism and the mounting frame 100 are adjusted so that the products can be stacked in alignment to meet the stacking requirements.

[0056] In summary, this embodiment, by setting up the mounting frame 100, enables the mounting frame 100 to be raised, lowered, and moved horizontally. Therefore, products to be stacked can be transferred and stacked into the circuit board hot melt production machine to meet the hot melt production needs.

[0057] This embodiment sets up a material handling mechanism, which includes a suction component 120 and a pressing component 130. Therefore, on the one hand, the suction component 120 can be used to conveniently pick up the products to be stacked, and on the other hand, the 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 moved around randomly when the suction component 120 is released, thus affecting the stacking quality.

[0058] In this embodiment, by setting up a material picking mechanism, the material picking component 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 rotate to align the stacked products vertically.

[0059] This embodiment sets up a detection mechanism, which 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.

[0060] In this embodiment, by setting up a detection mechanism, the detection mechanism includes a translation component 150. Therefore, the position of the CCD detector 140 can also be adjusted by the translation component 150, which is convenient for detecting the marking points of products to be stacked of different specifications and is easy to use.

[0061] Meanwhile, the inspection mechanism includes a translation component 150, which increases the horizontal movement distance of the CCD detector 140 and facilitates the inspection of products of different specifications.

[0062] Meanwhile, the detection mechanism includes a translation component 150, which allows the CCD detector 140 to move mostly in the horizontal direction without generating any lifting or lowering motion relative to the suction component 120. This does not affect the space occupied and allows the suction component 120 to be set to a larger size, enabling the suction component 120 to pick up a wide range of circuit board specifications, making the stacking device easy to use.

[0063] Meanwhile, the detection mechanism includes a translation component 150, and the lifting and lowering of the CCD detector 140 depends on the lifting and lowering of the mounting bracket 100, thus avoiding impact damage to the CCD detector 140 when it lifts and lowers alone.

[0064] In some specific embodiments of this utility model, the suction assembly 120 may include a suction plate 160, with a CCD detector 140 located above the suction plate 160. The suction plate 160 has a slot 170 for allowing the CCD detector 140 to detect the markings of the products to be stacked.

[0065] It is easy to understand that this embodiment provides a slot 170 to facilitate the CCD detector 140 in recognizing the marker points, so as to adapt to the situation where the product size is smaller than the suction plate 160.

[0066] In some specific embodiments of this utility model, 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 bracket 100. This satisfies the detection requirements and makes the solid area of ​​the suction plate 160 larger, thus avoiding affecting the suction capacity of the suction plate 160.

[0067] In some specific embodiments of this utility model, the number of CCD detectors 140 can be two, and the number of translation components 150 can be two sets, so that the two CCD detectors 140 can move closer to or further away from each other.

[0068] It is easy to understand that this embodiment, by setting two CCD detectors 140, can be applied to situations with two relative marker points, or to situations where the detectors are placed upside down.

[0069] Furthermore, the two CCD detectors 140 can move closer or further apart from each other, making them suitable for situations where the placement of circuit boards is varied and inconsistent, such as placing them in the center or against one side.

[0070] In some specific embodiments of this utility model, the rotating frame 110 may have a hollow cavity, the mounting frame 100 may have a first mounting part 180, the first mounting part 180 may be located in the hollow cavity, the top of the first mounting part 180 may be connected to the rotating frame 110, and a detection mechanism may be provided at the bottom of the first mounting part 180.

[0071] It is easy to understand that by making the rotating frame 110 have a hollow cavity, this embodiment can solve the problem of arranging the mounting frame 100 to connect the material picking mechanism and the detection mechanism at the same time, reduce the space occupied by the material stacking device in the horizontal direction, and facilitate material picking and detection.

[0072] At the same time, the vertical direction also makes the stacking device structure more compact, and allows the CCD detector 140 to get closer to the product to be inspected, improving the detection accuracy, and thus aligning and stacking products with higher precision.

[0073] In some specific embodiments of this utility model, the rotating frame 110 may include an upper mounting plate 190 and several side supports. The upper mounting plate 190 and several side supports cooperate to form a hollow cavity. The several side supports include a first side support 200 and a second side support 210. The bottom of the first side support 200 is used to connect to the suction plate 160, and the bottom of the second side support 210 is used to connect to the pressing assembly 130.

[0074] It is easy to understand that this embodiment also conveniently forms a hollow cavity by setting the upper mounting plate 190 and the side bracket, which not only meets the layout requirements, but also simplifies the structure, reduces manufacturing costs, and makes assembly easy.

[0075] In some specific embodiments of this utility model, the first side bracket 200 can be L-shaped, U-shaped or C-shaped, and the internal space of the first side bracket 200 is used to accommodate the translation component 150 passing through.

[0076] It is easy to understand that by giving the first side bracket 200 a specific shape, this embodiment can both avoid the translation component 150 of the detection mechanism and not affect the arrangement and stroke of the translation component 150, and facilitate the connection of the suction plate 160 to meet the need for fixing the suction plate 160.

[0077] In some specific embodiments of this utility model, the number of second side brackets 210 can be two, with the two second side brackets 210 located on opposite sides of the suction plate 160, and a crossbeam 220 provided between the two second side brackets 210, the crossbeam 220 connecting the suction plate 160.

[0078] It is easy to understand that in this embodiment, by setting a second side bracket 210, a crossbeam 220 is connected between the second side brackets 210, which can connect and fix the middle part of the suction plate 160, so as to avoid the middle part of the suction plate 160 from collapsing downward due to gravity and the shape characteristics of the suction plate 160 itself, thus avoiding affecting the flatness of the suction plate 160 and the suction effect.

[0079] In some specific embodiments of this utility model, the pressing assembly 130 may include a pressing block and a cylinder that drives the pressing block to rise and fall. The cylinder is installed on the second side bracket 210, so that the pressing assembly 130 can react quickly and fast.

[0080] In some specific embodiments of this utility model, the mounting frame 100 may be provided with a power mechanism that drives the rotating frame 110 to rotate. The power mechanism includes several power components 230 arranged in a ring. The power components 230 include a transverse moving member 240 connected to the mounting frame 100 and a longitudinal moving member 250 connected to the transverse moving member 240. The longitudinal moving member 250 is rotatably connected to the rotating frame 110. The mounting frame 100 is provided with a screw and sleeve transmission structure 260 that drives the transverse moving member 240 to move and a motor.

[0081] It is easy to understand that by setting up a number of power components 230 and arranging them as described above, this embodiment can achieve a rotatable connection while avoiding the use of common shaft and hole fits, which helps to increase the support strength. At the same time, it does not require setting up shafts and holes with large diameters, reducing the space occupied and facilitating the arrangement.

[0082] In this embodiment, there are four sets of power components 230. Each set of power components 230 will cause the rotating frame 110 to make circumferential tangential movement. The four sets of power components 230 cooperate to make the rotating frame 110 make four segments of circumferential tangential movement. The centers of the four segments of circumferential tangential movement coincide, causing the rotating frame 110 to rotate.

[0083] The longitudinal moving part 250 is rotatably connected to the rotating frame 110, which can meet the connection requirements when the rotating frame 110 rotates.

[0084] Meanwhile, since the material feeding 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 part 240 and the longitudinal moving part 250 are relatively short, they can still meet the usage requirements. Moreover, the four sets of power components 230

[0085] In some specific embodiments of this utility model, the mounting bracket 100 may also be provided with a compensating spring 270 that connects to the transverse sliding member 240.

[0086] It is easy to understand that by setting the compensation spring 270 in this embodiment, the screw and the sleeve can be kept in contact in the axial direction, reducing the transmission gap caused by manufacturing mis-contact, so that the four sets of power components 230 can work synchronously and improve the transmission reliability.
