Abstract
Description
Technical Field
[0001] This application relates to the field of PCB processing equipment technology, and in particular to cellular worktables, motion platforms, and PCB processing equipment. Background Technology
[0002] In the PCB manufacturing industry, the requirements for PCB processing equipment, such as processing efficiency and processing accuracy, are constantly increasing. At the same time, customers are also pursuing lower overall equipment costs and space requirements.
[0003] In related technologies, the working platform includes a support plate, an adhesive plate, and a fixing plate. The fixing plate is fixed to the support plate via the adhesive plate, and a power mechanism, such as a linear motor, is installed on the fixing plate. Since most of the force of the power mechanism is borne by the fixing plate, it needs to be made quite thick and heavy to prevent deformation of the fixing plate during operation, which would affect the movement accuracy.
[0004] However, the heavy mounting plate would result in higher overall machine tool costs and larger space requirements, failing to meet the demand. Utility Model Content
[0005] Therefore, it is necessary to provide a honeycomb worktable, motion platform, and PCB processing equipment to address the problem that the heavy fixed plate leads to high cost and large space occupation of the entire processing machine tool.
[0006] A cellular workbench, suitable for housing a power mechanism, the cellular workbench comprising:
[0007] honeycomb panels;
[0008] An adhesive plate is disposed on one side of the honeycomb panel; and
[0009] Fasteners are used to secure the power mechanism to the side of the adhesive plate away from the honeycomb plate.
[0010] In one embodiment, a through hole is provided on the honeycomb panel, the through hole penetrating the honeycomb panel, and the axial direction of the through hole is the same as the thickness direction of the adhesive board;
[0011] The fastener is a fastening bolt, which can extend into the through hole and fix the adhesive plate to the power mechanism.
[0012] In one embodiment, a support tube is embedded in the through hole, and the fastening bolt can extend into the support tube to fix the adhesive plate to the power mechanism.
[0013] In one embodiment, the honeycomb panel has a bearing surface for bearing a workpiece, and the adhesive plate is disposed on the side of the honeycomb panel opposite to the bearing surface.
[0014] In one embodiment, the adhesive plate is provided with anti-collision blocks on at least one side along the direction of movement.
[0015] A motion platform includes a slider, a power mechanism, and a honeycomb worktable, wherein the power mechanism and the slider are respectively fixed to the side of the adhesive plate away from the honeycomb plate.
[0016] In one embodiment, the power mechanism is a linear motor or a lead screw drive mechanism.
[0017] In one embodiment, a support block is provided on the side of the slider near the adhesive plate.
[0018] In one embodiment, the motion platform includes a cable chain mechanism, one end of which is fixedly connected to the adhesive plate.
[0019] A PCB processing equipment, the PCB processing equipment including a bed and the honeycomb worktable, or the PCB processing equipment including a motion platform;
[0020] The cellular worktable is movably connected to the bed. There are multiple cellular worktables, each of which is independently equipped with a power mechanism, or a power mechanism can drive multiple cellular worktables to move synchronously.
[0021] In the aforementioned honeycomb worktable, motion platform, and PCB processing equipment, the adhesive plate facing the honeycomb board can be fully adhered to the honeycomb board, forming a single integrated structure. Therefore, the forces generated by the power mechanism during operation are shared by the adhesive plate and the honeycomb board. The high rigidity of the honeycomb board provides stable support for the linear motor, preventing deformation and ensuring movement accuracy. In other words, this application eliminates the heavy fixed plate, replacing it with a relatively thin adhesive plate. The adhesive plate and honeycomb board simultaneously bear the forces of the power mechanism, ensuring stable support while reducing the overall machine tool size and cost. This also lowers the center of gravity and height of the entire honeycomb worktable, further improving the overall motion stability of the machine tool. Furthermore, the adhesive plate has a smaller mass compared to the heavy fixed plate, thus reducing the motion load. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0033] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium.

[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0035] As described in the background section, a traditional honeycomb workbench includes a honeycomb panel and a fixed plate disposed on one side of the honeycomb panel, with a power mechanism mounted on the fixed plate. To prevent deformation of the fixed plate during operation of the power mechanism, the fixed plate needs to be made quite thick and heavy.
[0036] Specifically, in traditional honeycomb workbenches, to facilitate the connection of the fixing plates, the four edges of the fixing plates are usually directly fixed to the honeycomb panels using fasteners. This results in a gap between the main body of the fixing plate and the honeycomb panel. The force generated by the power mechanism during operation is mainly borne by the fixing plate, making it prone to deformation. Therefore, the existing technology is to increase the thickness of the fixing plate to improve its load-bearing capacity and prevent deformation.
[0037] See Figure 1 and Figure 4 One embodiment of this application also provides a honeycomb workbench 100, suitable for housing a power mechanism. The honeycomb workbench 100 includes a honeycomb panel 110, an adhesive plate 120, and fasteners. The adhesive plate 120 is adhered to one side of the honeycomb panel 110, for example, by pasting. The fasteners are used to fix the power mechanism 220 to the side of the adhesive plate 120 away from the honeycomb panel 110.
[0038] In this embodiment, the adhesive plate 120, facing the honeycomb plate 110, can be fully adhered to the honeycomb plate 110 without any gaps, forming a single integrated structure. Therefore, the force generated by the power mechanism 220 during operation is shared by the adhesive plate 120 and the honeycomb plate 110. The high rigidity of the honeycomb plate 110 provides stable support for the linear motor 221, preventing deformation and ensuring movement accuracy. In other words, this application eliminates the heavy fixed plate, replacing it with a relatively thin adhesive plate 120. The adhesive plate 120 and the honeycomb plate 110 bear the force of the power mechanism 220, ensuring stable support while reducing the overall size and cost of the machine tool. Simultaneously, it lowers the center of gravity and height of the entire honeycomb worktable 100, further improving the overall motion stability of the machine tool. Furthermore, the adhesive plate 120 has a smaller mass compared to the heavy fixed plate, thus reducing the motion load.
[0039] The adhesive plate 120 can be a steel plate, such as a 45 steel plate or a 30 steel plate.
[0040] Specifically, the power mechanism 220 is a linear motor 221 or a lead screw drive mechanism 222.
[0041] Combination Figures 1-3 In some embodiments, the power mechanism 220 is a linear motor 221. The stator of the linear motor 221 is fixedly mounted, for example, on the bed of a PCB processing machine, and the mover of the linear motor 221 is fixed to the adhesive plate 120. When the linear motor 221 starts, it can drive the adhesive plate 120 and the honeycomb plate 110 to move. At this time, the vertical attraction force generated by the linear motor 221 during operation is jointly borne by the adhesive plate 120 and the honeycomb plate 110. The honeycomb plate 110 is not easily deformed, ensuring the accuracy of movement.
[0042] Combination Figures 4-6 In some other embodiments, the power mechanism 220 is a lead screw drive mechanism 222, which includes a lead screw and a nut seat. The lead screw is rotatably mounted on the bed, and one end of the lead screw is connected to a rotary motor. The nut seat is threaded onto the lead screw. When the rotary motor rotates, it drives the lead screw to rotate, causing the lead screw nut seat to move on the lead screw, which in turn causes the lead screw nut to move the adhesive plate 120 and the honeycomb plate 110. At this time, the force generated by the lead screw drive mechanism 222 during operation is shared by the adhesive plate 120 and the honeycomb plate 110. The honeycomb plate 110 is not easily deformed, ensuring the movement accuracy.
[0043] In some embodiments, combined with Figure 2 and Figure 3 The honeycomb panel 110 has a through hole 111 that penetrates the honeycomb panel 110. The axial direction of the through hole 111 is the same as the thickness direction of the adhesive plate 120. The fastener is a fastening bolt 121 that can extend into the through hole 111 and fix the adhesive plate 120 to the power mechanism 220.
[0044] In this embodiment, the honeycomb worktable 100 can be an X-axis honeycomb worktable and / or a Y-axis honeycomb worktable. The X-axis honeycomb worktable is slidably mounted on the machine tool bed along the X-axis direction, and the Y-axis honeycomb worktable is slidably mounted on the machine tool bed along the Y-axis direction. Taking the Y-axis honeycomb worktable as an example, the machine tool bed is provided with a guide rail extending along the Y-axis direction and a stator of a linear motor. The honeycomb worktable 100 is provided with a slider 210 and a mover of a linear motor 221. The stator and mover are coupled, that is, when the linear motor 221 is working, it can push the honeycomb worktable 100 to slide along the Y-axis direction. It should be noted that when the honeycomb worktable 100 is used to carry materials, the linear motor 221 is fixed to the bottom of the honeycomb plate 110 through the adhesive plate 120, so that the materials can be directly or indirectly placed on the honeycomb plate 110. Of course, the materials can also be directly or indirectly suspended at the bottom of the honeycomb plate 110, in which case the slider 210 and the linear motor 221 are fixed to the top of the honeycomb plate 110 through the adhesive plate 120.
[0045] The linear motor 221 has a threaded hole on the side near the adhesive plate 120, and the adhesive plate 120 also has a threaded hole. The threaded holes on the adhesive plate 120 and the threaded holes on the linear motor 221 are arranged one-to-one. During installation, the fastening bolt 121 is inserted into the through hole 111, and one end of the fastening bolt 121 is inserted into the threaded hole on the adhesive plate 120 and the threaded hole on the linear motor 221 in sequence until the fastening bolt 121 is tightened, that is, the fastening bolt 121 fixes the adhesive plate 120 and the linear motor 221.
[0046] Of course, the fastener can also be a snap-fit, that is, the power mechanism 220 can also be snapped onto the adhesive plate 120.
[0047] Furthermore, in combination Figure 3 A support tube 112 is embedded in the through hole 111, and a fastening bolt 121 can extend into the support tube 112 to fix the adhesive plate 120 to the power mechanism 220.
[0048] There are multiple through holes 111, and a support tube 112 is embedded in each through hole 111. The support tube 112 is used to define the inner wall of the through hole 111 and to guide the fastening bolt 121.
[0049] Specifically, the support tube 112 is a circular support tube.
[0050] The circular support tube is adapted to the shape of the fastening bolt 121. In other embodiments, the cross-section of the support tube 112 may also be rectangular, triangular, or other regular polygonal structures, as long as it can guide the fastening bolt 121.
[0051] The support tube 112 can be fixed in the through hole 111 by adhesive or by interference fit.
[0052] In some embodiments, the honeycomb panel 110 has a bearing surface for bearing a workpiece, and the adhesive plate 120 is disposed on the side of the honeycomb panel 110 away from the bearing surface.
[0053] In this embodiment, the bearing surface is located on the upper surface of the honeycomb plate 110 to support the workpiece. The adhesive plate 120 is disposed on the side of the honeycomb plate 110 away from the bearing surface, i.e., the power mechanism is fixed to the bottom of the adhesive plate 120. This application provides a through hole 111 in the honeycomb plate 110. A support tube 112 is embedded in the through hole 111. When installing the power mechanism, the fastening bolt 121 is screwed directly into the through hole 111 from top to bottom, thus fixing the adhesive plate 120 and the linear motor 221 by the fastening bolt 121. Compared with the related technology that requires fixing the power mechanism to the fixed plate from bottom to top, the above-described top-down installation method is simple and efficient.
[0054] In some embodiments, combined with Figure 4 The adhesive plate 120 is provided with a bumper block 130 on at least one side along the direction of movement.
[0055] In this embodiment, the anti-collision block 130 can be made of elastic pads or soft materials. Anti-collision blocks 130 are respectively provided on one or both sides of the adhesive plate 120 along the moving direction. The anti-collision blocks 130 are used to prevent the adhesive plate 120 from colliding with other structures and damaging the adhesive plate 120 during the movement.
[0056] An embodiment of this application also provides a motion platform, including a slider 210, a power mechanism 220, and a honeycomb worktable 100, wherein the power mechanism 220 and the slider 210 are respectively fixed on the side of the adhesive plate 120 away from the honeycomb plate 110.
[0057] In this embodiment, the power mechanism 220 is fixed to the adhesive plate 120, which is attached to the honeycomb panel 110. The power mechanism 220 is used to drive the adhesive plate 120 and the honeycomb panel 110 to move, so that the honeycomb worktable 100 can move on the bed. The slider 210 is used to cooperate with the guide rail on the bed to guide the movement of the adhesive plate 120 and the honeycomb panel 110.
[0058] In some embodiments, a support block is provided on the side of the slider 210 near the adhesive plate 120.
[0059] In this embodiment, the support block is disposed between the slider 210 and the adhesive plate 120. When different support blocks are replaced, the surface of the slider 210 can be at different horizontal heights so that the surface height of the slider 210 can be adapted to the surface height of the linear motor 221.
[0060] Specifically, the slider 210 is fixed to the support block by screws, and the support block is fixed to the adhesive plate 120 by screws.
[0061] In some embodiments, the cellular workbench 100 includes a drag chain mechanism 140, one end of which is fixedly connected to the adhesive plate 120.
[0062] In this embodiment, taking the honeycomb worktable 100 as a Y-axis honeycomb worktable, which is slidably mounted on the machine tool bed along the Y-axis direction, the cable chain mechanism 140 includes a cable chain adapter 141, a cable chain fixing member 142, and a cable chain 143. One end of the cable chain 143 is fixed to the cable chain fixing member 142, and the cable chain fixing member 142 is connected to the adhesive plate 120 through the cable chain adapter 141. The other end of the cable chain 143 is fixed to the machine tool bed. When the honeycomb plate 110 and the adhesive plate 120 move, the cable chain 143 can be moved. The cable chain 143 can house wires, cables, and other conduits inside, protecting them from external mechanical damage, wear, corrosion, and contamination from dust, oil, etc., extending the service life of the conduits and ensuring the electrical connection of the motion platform.
[0063] Specifically, the drag chain 143 is configured with a U-shaped or S-shaped structure to ensure the movement of the Y-axis honeycomb worktable.
[0064] One embodiment of this application also provides a PCB processing device, which includes a bed and a honeycomb worktable 100 as described above, or includes a motion platform as described above, wherein the honeycomb worktable 100 is movably connected to the bed.
[0065] In some embodiments, there are multiple cellular worktables 100, and each cellular worktable 100 can be independently configured with a power mechanism 220, that is, one power mechanism 220 independently drives one cellular worktable 100 to move, and the cellular worktables 100 can move synchronously or asynchronously with each other.
[0066] In other embodiments, a power mechanism 220 can drive multiple cellular workstations 100 to move synchronously. For example, two or more cellular workstations 100 are relatively fixed, and the power mechanism 220 is connected to one of the cellular workstations 100 and can drive the multiple relatively fixed cellular workstations 100 to move synchronously.
[0067] 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.
[0068] 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.
