Description

Technical Field

[0001] This utility model relates to the field of workpiece positioning platform devices, and in particular to a space-saving three-dimensional workpiece positioning platform device. Background Technology

[0002] Green ceramic sheets are the most basic functional material and component in LTCC technology. LTCC technology involves producing precisely thick and dense green ceramic sheets from low-temperature sintered ceramic powder. The required circuit patterns are then created on these green ceramic sheets using processes such as laser drilling, micro-hole injection, and precision conductor paste printing. Multiple passive components are embedded in a multilayer ceramic substrate, which is then stacked together. The inner and outer electrodes can be made of metals such as silver, copper, and gold, and the circuits are sintered at 900°C to create high-density circuits that do not interfere with each other in three-dimensional space. Alternatively, three-dimensional circuit boards with built-in passive components can be created, on which ICs and active devices can be mounted to form passive / active integrated functional modules. This allows for further miniaturization and high-density circuitry, making it particularly suitable for high-frequency communication components.

[0003] Green ceramic tiles are rectangular thin plates, typically ranging in size from 100*100mm to 500*500mm, with a thickness generally between 5-10mm. The production of green ceramic tiles involves processing steps such as laser drilling, edge chamfering, and micro-pore grouting. These processes all require three-dimensional positioning of the green ceramic tiles. In existing technologies, positioning devices for green ceramic tiles generally use cylinders positioned along the X and Y axes horizontally, and cylinders positioned along the Z axis vertically.

[0004] However, the equipment used for processing raw ceramic tiles, such as laser drilling and micro-hole injection, as well as the robotic arms used for handling, all need to be positioned above the raw ceramic tiles. This results in the occupation of the upper space of the workpiece during three-dimensional positioning, especially vertical positioning, which interferes with the upper operation and handling of the workpiece. Utility Model Content

[0005] To address the problem that vertical positioning in three-dimensional positioning occupies the upper space of the workpiece and interferes with upper work and handling in existing technologies, this utility model provides a space-saving three-dimensional workpiece positioning platform device.

[0006] The space-saving three-dimensional workpiece positioning platform device provided by this utility model adopts the following technical solution:

[0007] A space-saving three-dimensional workpiece positioning platform device includes a base plate with a side wall on one side. A chamfered groove is formed at the bottom of the base plate on the side wall. A workpiece angle correction mechanism that moves along the X-axis is provided at the top of the base plate near the side wall. A first fixing mechanism that moves along the Y-axis and cooperates with the side wall to fix the workpiece is provided at the top of the base plate. A second fixing mechanism that moves along the Y-axis and fixes the workpiece along the Z-axis after folding is provided at the top of the side wall.

[0008] Furthermore, the workpiece angle correction mechanism includes a correction cylinder and a correction plate. The correction cylinder is installed on the top of the base plate along the X-axis direction. The correction plate is fixedly installed at the output end of the correction cylinder. The correction plate is L-shaped and its end contacts the side wall.

[0009] Furthermore, the first fixing mechanism includes a first cylinder and a fixing plate. The first cylinder is installed on the top of the base plate along the Y-axis direction. The fixing plate is fixedly installed at the output end of the first cylinder. The fixing plate is L-shaped. The first cylinder pushes the workpiece to abut against the side wall through the fixing plate.

[0010] Furthermore, the second fixing mechanism includes a second cylinder, a guide plate, a mounting plate, a sliding seat, a guide column, a steering block, a spherical bearing, and a fixing block. Two guide plates are fixedly connected to the top of the base plate by bolts. A guide groove is formed through the side wall of each guide plate. A mounting plate is fixedly connected between the two guide plates. Two sliding seats are fixedly connected to the top of the mounting plate. A guide column is slidably connected inside each sliding seat. A flush plate is installed at the end of the guide column near the base plate via a nut. A spherical bearing is threaded through the end of the guide column through the flush plate. A steering block is rotatably connected to the guide column via the spherical bearing. A fixing block is rotatably connected to the side wall of the steering block. Guide wheels are rotatably connected to the side walls of the steering block and the fixing block near the guide plate, respectively. The guide wheels can roll along the guide groove. A second cylinder is fixedly installed on the top of the mounting plate. The output end of the second cylinder passes through the flush plate and is connected to the steering block via the spherical bearing.

[0011] Furthermore, the guide groove is L-shaped and extends from the Y-axis direction to the Z-axis direction.

[0012] Furthermore, two guide wheels are rotatably connected to one side wall of the fixed block, and the distance between the two guide wheels is less than the length of the guide groove extending in the Z-axis direction.

[0013] Furthermore, a pressure block is attached to the bottom surface of the fixing block that contacts the workpiece, and the pressure block is made of soft rubber.

[0014] Furthermore, the bottom surface of the fixing block that contacts the workpiece is provided with a clearance groove to avoid the position of the correction plate.

[0015] In summary, the beneficial effects of this utility model are as follows:

[0016] This invention, by setting a guide plate, a turning block, and a fixing block, changes the movement direction of the fixing block from along the Y-axis to along the Z-axis, thus changing the second fixing mechanism from a vertical to a horizontal orientation, significantly reducing the space occupied on the upper part of the workpiece in the vertical direction. By setting a workpiece angle correction mechanism, the orientation of the workpiece can be adjusted, preventing damage during fixing and ensuring accurate workpiece processing position. The first fixing mechanism, in conjunction with the side wall and base plate, can fix the workpiece to be processed on the side wall along the Y-axis. The second fixing mechanism, after fixing the workpiece with the first fixing mechanism, can fix the workpiece on the top of the base plate along the Z-axis. The chamfering groove allows for chamfering with a chamfering device. Attached Figure Description

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 The present invention will be further described in detail below:

[0026] This utility model discloses a space-saving three-dimensional workpiece positioning platform device, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this utility model discloses a space-saving three-dimensional workpiece positioning platform device, including a base plate 1. The base plate 1 has a side wall 11. A chamfered groove 12 is provided at the bottom of the base plate 1 on one side of the side wall 11. A workpiece angle correction mechanism that moves along the X-axis is provided at the top of the base plate 1 near the side wall 11. A first fixing mechanism that moves along the Y-axis and cooperates with the side wall 11 to fix the workpiece is provided at the top of the base plate 1. A second fixing mechanism that moves along the Y-axis and fixes the workpiece along the Z-axis after folding is provided at the top of the side wall 11. In this embodiment, the included angle between the side wall 11 and the base plate 1 is 90 degrees. The working state and principle of this application are explained in detail by setting a coordinate system with the base plate 1 and the side wall 11 as references. Horizontal movement along the extension direction of the side wall 11 is movement in the X-axis direction relative to the base plate 1. Horizontal movement perpendicular to the side wall 11 is movement in the Y-axis direction relative to the base plate 1. Vertical movement perpendicular to the base plate 1 is movement in the Z-axis direction relative to the base plate 1. By setting a workpiece angle correction mechanism, the orientation of the workpiece can be adjusted, which not only prevents damage to the workpiece during fixing but also ensures the accuracy of the workpiece's processing position. A first fixing mechanism, in conjunction with the side wall 11 and the base plate 1, can fix the workpiece to be processed onto the side wall 11 along the Y-axis. A second fixing mechanism, after fixing the workpiece with the first fixing mechanism, can fix the workpiece onto the top of the base plate 1 along the Z-axis. The position of the chamfer groove 12 is as follows... Figure 2 As shown, the outer inclined surface of the chamfer groove 12 is such that after the workpiece is fixed in three dimensions, one side of the workpiece will extend out of the chamfer groove 12, and then beveled with the help of a chamfering device.

[0027] like Figure 1 As shown, the workpiece angle correction mechanism includes a correction cylinder 21 and a correction plate 22. The correction cylinder 21 is mounted on the top of the base plate 1 along the X-axis direction. The correction plate 22 is fixedly mounted on the output end of the correction cylinder 21. The correction plate 22 is L-shaped, and its end contacts the side wall 11. In this embodiment, the specific shape of the correction plate 22 is as follows: Figure 1 As shown, the end of the straightening plate 22 extends along the side wall 11 and contacts the side wall 11. The end face of the straightening plate 22 is perpendicular to the side wall 11 in space. The straightening plate 22 pushes the workpiece for straightening through the end face of its end. When the straightening cylinder 21 is activated, the straightening cylinder 21 pushes the straightening plate 22 to move along the X-axis. When the end of the straightening plate 22 contacts the workpiece, the workpiece is straightened. After straightening, the straightening cylinder 21 returns to its original position.

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, the first fixing mechanism includes a first cylinder 31 and a fixing plate 32. The first cylinder 31 is mounted on the top of the base plate 1 along the Y-axis direction. The fixing plate 32 is fixedly mounted on the output end of the first cylinder 31. The fixing plate 32 is L-shaped. The first cylinder 31 pushes the workpiece to abut against the side wall 11 through the fixing plate 32. In this embodiment, the shape of the fixing plate 32 is as follows: Figure 1 As shown, the positional relationship between the first cylinder 31 and the corrective cylinder 21 is as follows: Figure 3 As shown, the stroke of the straightening cylinder 21 is relatively short, and the straightened workpiece is pushed by the fixing plate 32. After the workpiece is straightened, the first cylinder 31 is activated, pushing the workpiece through the fixing plate 32 and fixing the workpiece to the side wall 11.

[0029] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the second fixing mechanism includes a second cylinder 41, a guide plate 42, a mounting plate 43, a sliding seat 44, a guide column 45, a steering block 46, a joint bearing 47, and a fixing block 48. Two guide plates 42 are bolted to the top of the base plate 1. A guide groove 421 is formed through the side wall 11 of each guide plate 42. A mounting plate 43 is fixedly connected between the two guide plates 42. Two sliding seats 44 are fixedly connected to the top of the mounting plate 43. A guide column 45 is slidably connected inside each sliding seat 44. A flush plate 49 is installed at one end of the guide column 45 near the base plate 1 via a nut. A joint bearing is threaded through the flush plate 49 at the end of the guide column 45. Bearing 47 and guide post 45 are rotatably connected to steering block 46 via spherical bearing 47. A fixing block 48 is rotatably connected to the side wall 11 of steering block 46. Guide wheels 50 are rotatably connected to the side walls 11 of steering block 46 and fixing block 48 near guide plate 42, respectively. Guide wheels 50 can roll along guide groove 421. A second cylinder 41 is fixedly mounted on the top of mounting plate 43. The output end of the second cylinder 41 passes through flat plate 49 and is connected to steering block 46 via spherical bearing 47. Guide groove 421 is L-shaped and extends from the Y-axis direction to the Z-axis direction. In this embodiment, the shapes of guide plate 42, steering block 46, and fixing block 48 are as follows: Figure 5 , Figure 6As shown, by setting the guide plate 42, the moving direction of the fixed block 48 can be changed from moving along the Y-axis to moving along the Z-axis, so that the second fixing mechanism is changed from being set in the vertical direction to being set in the horizontal direction, which greatly reduces the space occupied by the upper part of the workpiece in the vertical direction. The mounting plate 43 is bolted to the side wall 11 of the guide plate 42, and the top of the mounting plate 43 has a mounting groove for mounting the sliding seat 44. By setting the flush plate 49, the extension of the two guide posts 45 is the same, ensuring that the moving direction of the steering block 46 and the fixed block 48 will not deviate. There are three spherical bearings 47, two of which are connected to the guide posts 45 and the other is connected to the output end of the second cylinder 41. Preferably, the surface of the guide wheel 50 is provided with a rubber layer to increase the friction between the guide wheel 50 and the inner wall of the guide groove 421 and reduce the noise when the guide wheel 50 moves.

[0030] like Figure 5 , Figure 6 As shown, two guide wheels 50 are rotatably connected to one side wall 11 of the fixing block 48. The distance between the two guide wheels 50 is less than the length of the guide groove 421 extending in the Z-axis direction. In this embodiment, two guide wheels 50 are provided on one side of the fixing block 48, and the two guide wheels 50 are respectively located at both ends of the fixing block 48. The advantage of doing so is that, since two points determine a straight line, when the two guide wheels 50 simultaneously enter the position of the guide groove 421 extending in the Z-axis direction, it can be ensured that the direction of the fixing block 48 is along the Z-axis direction and perpendicularly presses onto the top of the workpiece, thus improving stability.

[0031] like Figure 6 , Figure 7 As shown, a pressure block 481 is attached to the bottom surface of the fixing block 48 that contacts the workpiece. The pressure block 481 is made of soft rubber. In this embodiment, the position of the pressure block 481 is as follows: Figure 6 , Figure 7 As shown, the fixing block 48 is pressed onto the top of the workpiece by the pressure block 481. The fixing block 48, made of soft rubber, can act as a buffer to prevent the workpiece from being crushed.

[0032] like Figure 7 As shown, the bottom surface of the fixing block 48 that contacts the workpiece has a clearance groove 482 for avoiding the position of the correction plate 22; in this embodiment, the position of the clearance groove 482 is as follows: Figure 7 As shown, the length of the clearance groove 482 is slightly greater than the stroke of the straightening cylinder 21. By setting the clearance groove 482, the straightening plate 22 is prevented from interfering with the fixing block 48's fixing of the workpiece.

[0033] The implementation principle of this utility model embodiment is as follows:

[0034] First, the robotic arm will place the workpiece on the top of the base plate 1 near the side wall 11, and activate the straightening cylinder 21. The straightening cylinder 21 will push the straightening plate 22 to move along the X-axis. When the end of the straightening plate 22 contacts the workpiece, the workpiece will be straightened. After straightening, the straightening cylinder 21 will return to its original position.

[0035] Next, the first cylinder 31 is activated, and the fixing plate 32 pushes the workpiece and fixes the workpiece on the side wall 11;

[0036] Next, the second cylinder 41 is activated, which pushes the steering block 46 and the fixed block 48 to move along the Y-axis. The steering block 46 and the fixed block 48 will fold in the guide groove 421, so that the moving direction of the fixed block 48 changes from moving along the Y-axis to moving along the Z-axis and fixes the workpiece on the top of the base plate 1, thereby completing the three-dimensional fixation.

[0037] Finally, after the workpiece is fixed in three dimensions, one side of the workpiece will extend out of the chamfer groove 12. Then, in conjunction with the chamfering equipment, chamfering is performed. When multiple chamfering is required, the robotic arm will turn the workpiece and repeat the above process to complete multiple chamfering.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
