Description

Technical Field

[0001] This application relates to the field of PCB lamination technology, and in particular to PCB lamination production lines and their racks. Background Technology

[0002] In a PCB lamination production line, the material rack equipment mainly serves as a transfer and preparation point for incoming materials. Specifically, it neatly stacks the materials to be processed on the conveyor belt at fixed intervals so that they can be laminated by the laminator.

[0003] In related technologies, the material rack includes a frame, side plates set on the frame, and multiple guide mechanisms installed on the side plates. The multiple guide mechanisms are arranged in multiple layers on the inner side of the side plates, and the multiple guide mechanisms are used to convey multiple layers of materials simultaneously.

[0004] However, the guide mechanism is the most frequently used mechanical structure on the assembly line. The guide mechanism is prone to wear and tear, so it needs to be replaced frequently. When replacing it, the entire side plate needs to be disassembled, which makes maintenance difficult and costly. Utility Model Content

[0005] Therefore, it is necessary to provide a PCB lamination production line and its material rack to address the high maintenance difficulty caused by the guide mechanism being directly mounted on the side plate.

[0006] A material rack, the material rack comprising:

[0007] Frame;

[0008] The guiding mechanism includes multiple mounting seats and multiple idlers disposed on each mounting seat. The mounting seats are arranged sequentially at intervals along a first direction and are detachably fixedly connected to the frame. The multiple idlers on the same mounting seat are arranged sequentially along a second direction, and the idlers are rotatably connected to the mounting seat about a third direction axis. The first direction, the second direction, and the third direction are perpendicular to each other.

[0009] Multiple limiting components are detachably fixedly connected to the frame. The limiting components are located above the corresponding mounting bases. The limiting components extend along a second direction and are located on at least one side of the material along a third direction, for limiting the displacement of the material along the third direction. The projections of any limiting component and the guide mechanism in the planes containing the first and second directions do not coincide.

[0010] In one embodiment, the mounting base is spaced apart from the frame, and the mounting base is provided with rollers on both sides along the third direction. All the rollers on the same mounting base have the same upper surface height, and the upper surface height of the rollers is higher than the upper surface of the corresponding mounting base.

[0011] In one embodiment, the rollers disposed on both sides of the mounting base along the third direction are a first roller and a second roller, and the first roller and the second roller are alternately disposed along the second direction.

[0012] In one embodiment, the limiting component includes a first limiting plate and a second limiting plate, the first limiting plate and the second limiting plate being set at an angle, the first limiting plate being fixedly connected to the frame, and the second limiting plate extending from the first limiting plate toward the side closer to the idler roller in a third direction.

[0013] In one embodiment, the second limiting plate is provided with chamfers at both ends along the second direction.

[0014] In one embodiment, the guiding mechanism includes a connecting rod extending in a third direction, one end of which is detachably connected to the mounting base and the other end of which is detachably connected to the frame.

[0015] In one embodiment, the guiding mechanism includes a support rod, a bearing, and a sliding plate. The idler roller is sleeved on the support rod through the bearing. Sliding plates are respectively provided at both ends of the idler roller along a third direction. The support rod is detachably connected to the mounting base.

[0016] In one embodiment, the idler roller has a first end, a middle portion, and a second end arranged sequentially along a third direction;

[0017] The diameter of the idler roller gradually increases along the direction from the first end to the middle.

[0018] The diameter of the roller gradually decreases along the direction from the middle to the second end.

[0019] In one embodiment, there are at least two guide mechanisms, which are spaced apart on the frame along a third direction.

[0020] In one embodiment, the plurality of limiting components are divided into a first group of limiting components and a second group of limiting components. The plurality of limiting components in the first group of limiting components correspond one-to-one with the plurality of mounting seats in the guide mechanism at one end along a third direction, and the plurality of limiting components in the second group of limiting components correspond one-to-one with the plurality of mounting seats in the guide mechanism at the other end along a third direction.

[0021] A PCB lamination production line includes a PCB laminator and a material rack, wherein the PCB laminator is located on one side of the material rack's discharge port.

[0022] In the aforementioned PCB lamination production line and its material rack, the extension direction of the mounting base is perpendicular to the axial direction of the idler rollers, and the arrangement direction of the multiple idler rollers is the same as the extension direction of the mounting base. This allows the material to be transported along the extension direction of the mounting base when the idler rollers rotate, thus transporting the material from the loading end to the unloading end of the frame. A limiting component is detachably fixed to the mounting base, extending along a second direction to guide the material and ensure its transport from the loading end to the unloading end. Idler rollers of the same layer are directly mounted on the frame via the mounting base. When the idler rollers wear, only the mounting base of the corresponding layer needs to be removed, without affecting the transmission of other layer guide mechanisms. Disassembly is easy and maintenance costs are low. Simultaneously, the limiting component is directly and detachably fixed to the frame, located above the guide mechanism. There is no direct connection between the limiting component and the guide mechanism. When the limiting component wears, it can be disassembled and replaced individually without simultaneously replacing the corresponding guide mechanism, thus reducing material waste.

[0034] See Figure 1 and Figure 2 An embodiment of this application provides a material rack, which includes a frame body 100, a guiding mechanism 200, and multiple limiting components 300. The guiding mechanism 200 includes multiple mounting seats 210 and multiple rollers 220 rotatably disposed on each mounting seat 210. The multiple mounting seats 210 are arranged at intervals along a first direction ZZ' and are detachably fixedly connected to the frame body 100. The multiple rollers 220 on the same mounting seat 210 are arranged sequentially along a second direction YY', and the rollers 220 and the mounting seat 210 rotate around a third direction XX'. The first direction ZZ', the second direction YY', and the third direction XX' are perpendicular to each other; multiple limiting components 300 are detachably fixedly connected to the frame 100, the limiting components 300 are located above the corresponding mounting base 210, the limiting components 300 extend along the second direction YY', and the limiting components 300 are located on at least one side of the material along the third direction XX' to limit the displacement of the material along the third direction XX', wherein the projections of any limiting component 300 and the guide mechanism 200 on the plane containing the first direction ZZ' and the second direction YY' are not coincident.

[0035] Specifically, the first direction ZZ' can be the height direction, and multiple guide mechanisms 200 are spaced apart along the height direction so that multiple guide mechanisms 200 can be used to simultaneously carry multiple layers of materials. Each mounting base 210 is provided with multiple idlers 220, the extension direction of the mounting base 210 is the second direction YY', and the axial direction of the idler 220 is the third direction XX', that is, the extension direction of the mounting base 210 is perpendicular to the axial direction of the idler 220, and the arrangement direction of the multiple idlers 220 is the same as the extension direction of the mounting base 210, so that when the idler 220 rotates, the material can be transported along the extension direction of the mounting base 210 to transport the material from the loading end to the unloading end of the frame 100. The limiting component 300 is located above the mounting base 210. The limiting component 300 extends along the second direction YY' and is located on at least one side of the material along the third direction XX'. It is used to limit the displacement of the material along the third direction XX' to ensure that the material can be transported from the loading end to the unloading end along the second direction YY'.

[0036] In this embodiment, each guide mechanism 200 is directly mounted on the frame 100 via a mounting base 210. When the idler roller 220 wears, only the mounting base 210 of the corresponding layer needs to be removed, without affecting the transmission of guide mechanisms 200 on other layers. Furthermore, disassembly is easy and maintenance costs are low. Simultaneously, the limiting component 300 is directly fixed to the frame 100, located above the guide mechanism 200. The projections of any limiting component 300 and the guide mechanism 200 onto the plane containing the first direction ZZ' and the second direction YY' do not coincide. That is, there is no direct connection between the limiting component 300 and the guide mechanism 200. When the limiting component 300 wears, it can be disassembled and replaced individually without simultaneously replacing the corresponding guide mechanism 200, thus reducing material waste.

[0037] The material can be a PCB board, which is placed on a tray. The tray is used to transport the PCB board from the loading side to the unloading side of the rack. The frame 100 includes multiple uprights arranged along the first direction ZZ', which are connected by crossbars. The mounting base 210 and the limiting assembly 300 are directly mounted on the uprights.

[0038] Combination Figure 3 In some embodiments, there are at least two guide mechanisms 200, and at least two guide mechanisms 200 are arranged at intervals along a third direction XX' on the frame 100.

[0039] In this embodiment, there are two sets of guide mechanisms 200, which are spaced apart along the third direction XX' to support the pallet on both sides along the third direction XX', thus ensuring the pallet's transport. Of course, there can also be three or four sets of guide mechanisms 200 to increase the support strength for the pallet.

[0040] Furthermore, the multiple limiting components 300 are also divided into a first group of limiting components and a second group of limiting components. The first group of limiting components and the second group of limiting components are arranged at intervals along the third direction XX'. The multiple limiting components in the first group of limiting components correspond one-to-one with the multiple mounting seats in the guide mechanism at one end along the third direction, and the multiple limiting components in the second group of limiting components correspond one-to-one with the multiple mounting seats in the guide mechanism at the other end along the third direction.

[0041] In this embodiment, at least two of the guide mechanisms 200 are spaced apart along the third direction XX' on the frame 100. For example, a first guide mechanism, a second guide mechanism, and a third guide mechanism are spaced apart along the third direction XX' on the frame 100. Multiple limiting components in the first set of limiting components correspond one-to-one with multiple mounting seats in the first guide mechanism, and multiple limiting components in the second set of limiting components correspond one-to-one with multiple mounting seats in the third guide mechanism. That is, each pallet layer has limiting components 300 on both sides along the third direction XX'. The two limiting components 300 simultaneously limit the pallet on both sides along the third direction XX', thereby ensuring that the limiting components 300 can be transported from the loading end to the unloading end along the second direction YY'.

[0042] In some embodiments, the mounting base 210 is spaced apart from the frame 100, and the mounting base 210 is provided with rollers 220 on both sides along the third direction XX'. All the rollers 220 on the same mounting base 210 have the same upper surface height, and the upper surface height of the rollers 220 is higher than the upper surface of the corresponding mounting base 210.

[0043] In this embodiment, the mounting base 210 is spaced apart from the frame 100 so that a roller 220 can be installed between the mounting base 210 and the frame 100. The upper surface of the roller 220 is higher than the upper surface of the corresponding mounting base 210. That is, when material is placed on the guide mechanism 200 via a pallet, the pallet can be supported by the roller 220. When the roller 220 rotates, it can drive the pallet to move along the second direction YY', thereby allowing the pallet and the material on it to move from the loading end to the unloading end. The mounting base 210 is provided with rollers 220 on both sides along the third direction XX', and the upper surface height of all rollers 220 on the same mounting base 210 is the same. This increases the number of rollers 220 and the number of stress points on the pallet, thereby reducing the wear of each roller 220, improving the service life of the guide mechanism 200, and also helping to distribute the stress on the pallet evenly, reducing local deformation of the pallet.

[0044] Specifically, the rollers 220 disposed on both sides of the mounting base 210 along the third direction XX´ are the first roller 221 and the second roller 222, and the first roller 221 and the second roller 222 are alternately disposed along the second direction YY´.

[0045] In this embodiment, along the second direction YY´, a plurality of first rollers 221 are sequentially arranged on the mounting plate, and a second roller 222 is arranged between each two adjacent first rollers 221. That is, the first rollers 221 and the second rollers are evenly arranged on both sides of the mounting base 210, which further improves the uniformity of force on the tray.

[0046] In some embodiments, the limiting component 300 includes a first limiting plate 310 and a second limiting plate 320. The first limiting plate 310 and the second limiting plate 320 are set at an angle. The first limiting plate 310 is fixedly connected to the frame 100. The second limiting plate 320 extends from the first limiting plate 310 toward the side closer to the idler roller 220 along a third direction XX'.

[0047] In this embodiment, the first limiting plate 310 and the second limiting plate 320 are perpendicular. The first limiting plate 310 is fixed to the frame 100 by screws. The second limiting plate 320 extends from the first limiting plate 310 along the third direction XX' towards the side closer to the idler roller 220. That is, the second limiting plate 320 is used to limit the pallet on the idler roller 220 on both sides along the third direction XX', so that the pallet can be transported along the second direction YY'.

[0048] Furthermore, the second limiting plate 320 has chamfers at both ends along the second direction YY´.

[0049] In this embodiment, the chamfer is a rounded chamfer, which is used to enable the pallet to quickly enter into the material rack and quickly move out of the material rack, and at the same time prevent the second limiting plate 320 from rubbing against the material and damaging the material during the loading and unloading process.

[0050] In some embodiments, the guide mechanism 200 includes a connecting rod 230 extending along a third direction XX', one end of the connecting rod 230 being detachably connected to the mounting base 210 and the other end being detachably connected to the frame 100.

[0051] In this embodiment, the connecting rod 230 is used to connect the mounting base 210 to the frame 100 on the one hand, and to space the mounting base 210 from the frame 100 on the other hand, so that the mounting base 210 can be provided with rollers 220 at both ends along the third direction XX'.

[0052] The connecting rod 230 is threaded and passes through the mounting base 210 and the frame 100 in sequence before being locked by a nut. A sleeve is fitted on the connecting rod 230 between the mounting base 210 and the frame 100 to space the mounting base 210 from the frame 100 and ensure the distance between them. The mounting base 210 is detachably connected to the frame 100 by at least two screws. Specifically, both ends and the middle of the mounting base 210 are detachably connected to the frame 100 by screws.

[0053] Combination Figure 4In some embodiments, the guide mechanism 200 includes a support rod 240, a bearing 250, and a slide plate 260. The idler roller 220 is sleeved on the support rod 240 through the bearing 250. Slide plates 260 are respectively provided at both ends of the idler roller 220 along the third direction XX'. The support rod 240 is detachably connected to the mounting base 210.

[0054] In this embodiment, the idler roller 220 is sleeved on the support rod 240 via a bearing 250. The bearing 250 allows the idler roller 220 to rotate relative to the support rod 240. Sliding plates 260 are respectively provided on both sides of the idler roller 220 along its axial direction, and the sliding plates 260 are used to limit the movement of the idler roller 220. The support rod 240 is detachably connected to the mounting base 210. When it is necessary to replace a specific idler roller 220, it is only necessary to remove the corresponding idler roller 220 from the mounting base 210 and then replace it with a new idler roller 220.

[0055] In some embodiments, the idler roller 220 has a first end, a middle portion, and a second end arranged sequentially along a third direction XX'; the diameter of the idler roller 220 gradually increases along the direction from the first end to the middle portion; and the diameter of the idler roller 220 gradually decreases along the direction from the middle portion to the second end.

[0056] In this embodiment, the diameter of the idler roller 220 is largest at the middle along the third direction XX', and smaller at the two sides of the middle, so that the idler roller 220 has a drum-shaped structure. When a pallet containing material is placed on the idler roller 220, due to the gap between the two sets of conveyors, the central area of ​​the pallet will bend downward due to the weight of the material and its own weight, so that the bottom side of the pallet is arc-shaped. At this time, the idler roller 220 also bends accordingly. Because the idler roller 220 has a drum-shaped structure, the idler roller 220 and the pallet can make adaptive contact, so that the contact area between the idler roller 220 and the pallet is always kept to a minimum, thereby reducing the wear of the pallet.

[0057] One embodiment of this application also provides a PCB lamination production line, including a PCB laminator and a material rack, wherein the PCB laminator is located on one side of the material rack's unloading port. The material is circuit boards. After multiple circuit boards are integrated on the material rack, they are transferred from the unloading port to the PCB laminator for lamination. The same layer of support rollers 220 in the material rack is directly mounted on the frame 100 via mounting bases 210. When the support rollers 220 wear, only the corresponding layer's mounting base 210 needs to be removed, without affecting the transmission of other layer guide mechanisms 200. Furthermore, disassembly is easy and maintenance costs are low. Simultaneously, the limiting component 300 is directly fixed to the frame 100, and there is no connection between the limiting component 300 and the guide mechanism 200. When the limiting component 300 wears, it can be disassembled and replaced separately without simultaneously replacing the corresponding guide mechanism 200, thus reducing material waste.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
