Description

Technical Field

[0001] The present application relates to the technical field of etching equipment, and in particular to an ultra-wide conveying device for an etching machine. Background Art

[0002] During the PCB production process, it is often necessary to use conveying equipment to move the products to be processed. The conveying width of the commonly used conveyors is generally 700-900mm, and conveying equipment exceeding 1000mm is rare. The reason is that if the conveying width is too large, the supporting force of the rollers is not strong enough, and the suspended area in the middle of the conveyed product will sink under its own gravity, thus causing the board to be stuck and affecting the smooth conveying process.

[0003] To solve the above problem, the existing technology solves it by adding a support plate, but the support plate located in the middle will block part of the area of ​​the product to be transported, resulting in the inability of the drug liquid to contact the area, thereby affecting the processing of the product and the product cannot be used normally. Utility Model Content

[0004] The main purpose of this application is to provide an ultra-wide conveying device for an etching machine, aiming to solve the defect of small conveying width in the prior art.

[0005] This application achieves the above objectives through the following technical solutions:

[0006] An ultra-wide conveying device for an etching machine, comprising:

[0007] A plurality of drive modules, each of which is independent of each other and arranged in sequence along the material conveying direction;

[0008] A plurality of support bars are arranged in each driving module in sequence along the material conveying direction, and any two adjacent support bars are staggered; the support bars and the suspended areas of the products to be processed are abutted against each other to provide support for the products to be processed.

[0009] Optionally, the offset distance between two adjacent support bars is 50-100 mm.

[0010] Optionally, the support bar is made of titanium steel, and the width of the support bar is 25-35 mm.

[0011] Optionally, the driving module includes a driving shaft and a driven shaft, the driving shaft is respectively connected to the driven shafts by power, and a plurality of driving rollers are provided on the driving shaft and the driven shafts, and each driving wheel is respectively in contact with the product to be processed.

[0012] Optionally, both the driving shaft and the driven shaft are provided with limiting grooves arranged along their axes, and each of the driving rollers is provided with a limiting block adapted to the limiting grooves.

[0013] Optionally, along the axial direction of the limiting groove, each limiting block is provided with a locking block, and each locking block is threadedly connected with a locking screw.

[0014] Optionally, a plurality of connection holes are provided on the top surface of the support bar along the length direction of the support bar, and a rolling support module for supporting the product to be processed is provided in each of the connection holes.

[0015] Optionally, the rolling support module includes a connecting rod, one end of which is threadedly connected to the connecting hole along the axis of the connecting rod, and the other end of the connecting rod is rotatably provided with a supporting ball.

[0016] Optionally, a limiting ring with a regular hexagonal structure is provided on the outer peripheral surface of the connecting rod, and along the axial direction of the connecting hole, the limiting ring abuts against the support bar.

[0017] Optionally, a first rotating cavity is further provided on the top surface of the connecting rod, a limiting cover is further provided on the connecting rod, a second rotating cavity is provided on the limiting cover, the supporting ball is provided in the first rotating cavity, a through hole is further provided on the second rotating cavity, and the top of the supporting ball passes through the through hole to contact the product to be processed.

[0018] Compared with the prior art, this application has the following beneficial effects:

[0019] The present application includes several drive modules and several support bars, each of which is independent of each other and arranged in sequence along the material conveying direction; each of the support bars is arranged in sequence in each of the drive modules, and any two adjacent support bars are staggered; the support bars and the suspended areas of the products to be processed are in contact with each other to provide support for the products to be processed.

[0020] Since any two adjacent support bars are staggered, during the operation of the equipment, after the product to be processed enters different areas, the support bar and its contact area will change, that is, the support bar will not always maintain contact with a specific area of ​​the product to be processed. When a certain area of ​​the product to be processed cannot contact the medicine due to the obstruction of the support bar, after the support bar is switched, the area will contact the medicine again, thereby avoiding the situation where a certain area of ​​the product to be processed cannot always contact the medicine due to the obstruction of the support bar, thereby affecting the consistency of the product; that is, the technical defect of not being able to use support bars in the prior art is solved by setting the support bars, and the technical solution of adding support bars to the conveying device is realized. By being able to form a strong support for the middle area of ​​the product to be processed, it is avoided that the suspended area in the middle sinks under the action of its own gravity. Therefore, the conveying equipment can complete the material transportation with a larger width, effectively increasing the width of the conveying device.

[0021] Compared with the existing technology, the present application completely solves the technical problem that the medicine cannot come into contact with the product to be processed by simply staggering the support bars, thereby solving the biggest difficulty in installing the support bars and meeting the installation conditions of the support bars, thereby effectively increasing the conveying width of the conveying device; its technical effect is significant and the technical solution is simple.

[0032] Implementation Method 1

[0033] Reference Figures 1 to 4 This embodiment, as an optional embodiment of the present application, discloses an ultra-wide conveying device for an etching machine, comprising a plurality of drive modules and a plurality of support bars 1, each of the drive modules operating independently, and arranged in sequence along the material conveying direction;

[0034] The driving module includes a driving shaft 2 and a driven shaft 3. The driving shaft 2 is connected to an external power device, such as a motor through a coupling; each driven shaft 3 is respectively connected to the driving shaft 2 by power, such as through the cooperation of a sprocket and a chain or a synchronous wheel and a synchronous belt;

[0035] A plurality of driving rollers 4 are provided on the driving shaft 2 and the driven shaft 3, and the top surfaces of the driving rollers 4 are located in the same horizontal plane to ensure that the driving rollers 4 can contact the surface of the product to be conveyed, thereby realizing the conveying of the material;

[0036] Each of the driving devices is provided with a support bar 1, which is separated from the driving device, that is, the support bar 1 is only provided in the transmission area of ​​the driving device, but its position is fixed and is not controlled by the driving device;

[0037] Reference Figure 1 , along the material conveying direction, each of the support bars 1 is sequentially arranged in each of the driving modules, and any two adjacent support bars 1 are staggered, that is, there is a certain offset between any two adjacent support bars 1 in the axial direction of the driving shaft 2 or the driven shaft 3;

[0038] It should be noted that the above-mentioned offset spacing is determined according to the actual width, and the offset directions can be consistent or inconsistent, that is, all the support bars 1 can be offset toward the same end along the axis of the driving shaft 2, or toward both ends of the axis of the driving shaft 2, or alternately offset toward both ends of the axis of the driving shaft 2 according to a certain rule;

[0039] However, it should be pointed out that no matter which method is used to arrange the support bars 1, the support bars 1 should be evenly distributed throughout the entire conveying width to ensure uniform force on the products to be conveyed.

[0040] The top surface of the support bar 1 is flush with the top surface of each support roller, so as to abut against the suspended area of ​​the product to be processed to provide support for the product to be processed;

[0041] Furthermore, along the axial direction of the driving shaft 2, a limiting groove 5 is provided on the driving shaft 2 and the driven shaft 3, and a limiting block 6 is provided on each of the driving rollers 4, and each of the limiting blocks 6 is inserted into the limiting groove 5; at the same time, along the axial direction of the limiting groove 5, a locking block 7 is provided on each of the limiting blocks 6, and each of the locking blocks 7 is threadedly connected to a locking screw 8;

[0042] In the axial direction around the driving shaft 2 or the driven shaft 3, the limiting groove 5 and the limiting block 6 are in contact with each other, thereby better driving the driving rollers 4 to rotate and preventing the driving rollers 4 from being dislocated from the driving shaft 2 or the driven shaft 3;

[0043] Secondly, in the above structure, the position of the driving roller 4 can also be adjusted along the axial direction of the driving shaft 2 or the driven shaft 3, thereby meeting the transmission requirements of standard products and improving the flexibility of equipment use.

[0044] Furthermore, a plurality of connection holes 9 are provided on the top surface of the support bar 1. The connection holes 9 are arranged at equal intervals along the length direction of the support bar 1. A rolling support module is threadedly connected in each of the connection holes 9.

[0045] The rolling support module includes a connecting rod 10, along the axis of the connecting rod 10, a threaded rod is provided at the bottom end of the connecting rod 10, and is threadedly connected to the connecting hole 9 through the threaded rod;

[0046] A limiting ring 12 is further provided in the middle of the connecting rod 10. The limiting ring 12 has an overall regular hexagonal structure. The limiting ring 12 allows the connecting rod 10 to be rotated conveniently and quickly, thereby achieving rapid installation of the equipment. On the other hand, the limiting ring 12 can accurately determine whether the equipment is installed in place, thereby ensuring contact with the product to be transported, which is conducive to improving the installation accuracy of the equipment.

[0047] The top of the connecting rod 10 is provided with a first rotation cavity 13, and a limit cover 14 is threadedly connected to the top of the connecting rod 10. The limit cover 14 is provided with a second rotation cavity 15. The first rotation cavity 13 and the second rotation cavity 15 are spliced ​​together to form a spherical cavity, in which a support ball 11 is placed. The second rotation cavity 15 is also provided with a through hole 16, and the top of the support ball 11 passes through the through hole 16 to contact the product to be processed;

[0048] The rotation of the support ball 11 can effectively reduce the friction between the support bar 1 and the product to be conveyed, thereby avoiding unnecessary scratches. Secondly, the support ball 11 and the product to be conveyed are in point contact. Therefore, after the rolling support module is provided, the shielding area of ​​the support bar can be minimized as much as possible, ensuring that the liquid medicine is in full contact with the product.

[0049] Compared with the existing technology, the present application completely solves the technical problem that the medicine cannot come into contact with the product to be processed by simply staggering the support bars, thereby solving the biggest difficulty in installing the support bars and meeting the installation conditions of the support bars, thereby effectively increasing the conveying width of the conveying device; its technical effect is significant and the technical solution is simple.

[0050] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
