Description

Technical Field

[0001] This invention relates to the field of workpiece processing technology, and in particular to a flipping and alignment device and method. Background Technology

[0002] With advancements in production and improvements in people's living standards, the use of crystal car ornaments has gradually expanded from high-end customized models to ordinary mid-range models. For the production of ordinary mid-range models, the original custom handcrafting methods used for high-end customized models can no longer meet the needs of production applications in terms of both production costs and efficiency.

[0003] Car crystal ornaments are mainly used in parts such as gear levers, knobs, buttons, and paddle shifters. They are popular and highly regarded due to their bright, clear surface, comfortable feel, and attractive appearance. During crystal processing, a CNC 4-axis surface grinder is typically used to achieve a smooth and clear surface. The workpiece is clamped in a chuck, and the axis of the chuck rotates to adjust the crystal facets to be ground. For workpieces requiring double-sided processing, such as knobs, the workpiece must be flipped after one side is finished before clamping it for processing the other side. Currently, manual flipping or ball-adhesive flipping is commonly used. These methods often encounter positioning inaccuracies, resulting in misalignment of the cut edges between the finished and previously processed sides, leading to poor appearance or dimensional defects.

[0004] Patent application CN201124327Y discloses a ball-adhesive machine, which is only suitable for batch flipping and limited to the positioning of aluminum bars. Furthermore, the long-term high-temperature baking required during the burning of sealing wax during use leads to decreased accuracy and a short service life. Manual flipping, on the other hand, relies excessively on operator experience and is inefficient. The ball-adhesive machine's flipping capabilities are limited and cannot meet the requirements of existing automated equipment for clamp positioning. Therefore, finding a device or method to solve the bottleneck in process yield caused by flipping and alignment has become a pressing technical problem for those skilled in the art.

[0005] Therefore, existing technologies still need improvement. Summary of the Invention

[0050] like Figures 1 to 4 As shown, some embodiments of the present invention disclose a flipping and alignment device, including a base 1, a guide post, an upper fixing fixture, a lower fixing fixture, a positioning component, an upper chuck 13, a lower chuck, and a lifting component. The guide post is vertically fixed to the base 1. The upper fixing fixture has an upper sliding hole, and the lower fixing fixture has a lower sliding hole. The upper sliding hole and the lower sliding hole are fitted onto the guide post from top to bottom. The positioning component positions the upper fixing fixture on the guide post, and the lifting component connects to the lower fixing fixture so that the lower fixing fixture can move up and down along the guide post. The upper chuck 13 is detachably mounted on the upper fixing fixture, and the lower chuck is detachably mounted on the lower fixing fixture. The upper chuck 13 and the lower chuck are arranged opposite to each other. The lower end of the upper chuck 13 has an upper mounting portion for mounting the workpiece 14 to be flipped, and the upper end of the lower chuck has a lower mounting portion for mounting the workpiece 14 to be flipped. This embodiment uses the guide post for guiding and positioning, ensuring the stability of the lower fixing fixture's up and down movement, thereby achieving high accuracy in flipping and positioning. The upper and lower fixed fixtures, together with the lifting assembly, enable the workpiece 14 to be flipped and positioned between the two chucks. The structure is simple, and the installation and disassembly are convenient and quick, which improves the work efficiency of the operator.

[0051] In use, first, install the lower chuck with the workpiece 14 to be flipped onto the lower fixed fixture, and then install the upper chuck 13 onto the upper fixed fixture. Lift the lower fixed fixture using the lifting assembly, aligning the top of the workpiece 14 on the lower chuck with the lower end of the upper chuck 13. Then, control the lifting assembly to lower the lower fixed fixture, causing the workpiece 14 to leave the lower chuck and be flipped and positioned onto the upper chuck 13. Remove the upper chuck 13 to complete the flipping of the workpiece 14. To ensure the workpiece 14 can smoothly detach from the lower chuck while being secured by the upper chuck 13, an adhesive with a viscosity greater than that of the lower chuck can be applied to the upper chuck 13.

[0052] In this embodiment, the upper and lower fixing fixtures are designed as sliding blocks, which effectively improves accuracy. The method of stacking two sliding blocks together for processing improves the concentricity and contour of the upper and lower sliding blocks, thereby ensuring the static accuracy of the alignment equipment.

[0053] The flipping and alignment device disclosed in some embodiments of the present invention, based on the above embodiments, includes an upper fixing fixture for mounting the upper chuck 13. This fixture may include an upper fixing part 3 and an upper movable part 4 that are detachably mounted together. An upper sliding hole is provided in the upper fixing part 3. Furthermore, the upper fixing part 3 is provided with an upper fixing half-groove, and the upper movable part 4 is provided with an upper movable half-groove. When the upper movable part 4 is mounted on the upper fixing part 3, the upper fixing half-groove and the upper movable half-groove are combined to form an upper cavity for fixing the upper chuck 13. The mounting or dismounting of the upper fixing part 3 and the upper movable part 4 facilitates the mounting, flipping, positioning, and removal of the upper chuck 13.

[0054] Similarly, the lower fixing fixture may also include a lower fixing part 2 and a lower movable part 5. The lower fixing part 2 is provided with a lower fixing half-groove, and the lower movable part 5 is provided with a lower movable half-groove. When the lower movable part 5 is installed on the lower fixing part 2, the lower fixing half-groove and the lower movable half-groove are combined to form a lower cavity for fixing the lower chuck. By installing or separating the lower fixing part 2 and the lower movable part 5, the installation, flipping and positioning operation, and removal of the lower chuck can be facilitated.

[0055] In some embodiments, for the upper fixed fixture, the first end of the upper movable part 4 can be hinged to the upper fixed part 3 via a hinge assembly, and the second end of the upper movable part 4 is detachably connected to the upper fixed part 3 via a snap-fit ​​assembly. When it is necessary to separate the upper movable part 4 from the upper fixed part 3, the snap-fit ​​assembly can be opened, and the upper movable part 4 can be rotated around its first end, thereby exposing the upper movable semi-groove on the upper movable part 4 to install the upper chuck 13 therein. Similarly, for the lower fixed fixture, the first end of the lower movable part 5 can be hinged to the lower fixed part 2 via a hinge assembly, and the second end of the lower movable part 5 is detachably connected to the lower fixed part 2 via a snap-fit ​​assembly. When it is necessary to separate the lower movable part 5 from the lower fixed part 2, the snap-fit ​​assembly can be opened, and the lower movable part 5 can be rotated around its first end, thereby exposing the lower movable semi-groove on the upper movable part 4 to install the lower chuck therein. Of course, the present invention can be realized as long as the installation method of the upper movable part 4 and the upper fixed part 3, as well as the lower movable part 5 and the lower fixed part 2, can achieve either opening or alignment and fixing. Therefore, it will not be described in detail here. In this embodiment, the single-door design of the upper movable part 4 and the lower movable part 5, combined with multiple workpiece mounting positions, results in a simple structure, convenient and quick installation and disassembly, and improves the work efficiency of operators.

[0056] like Figures 1 to 3 As shown, the hinge assembly can be connected by a hinge 10, and the latch assembly is controlled by a handle 11. A slot is provided in the upper fixed part 3 or the lower fixed part 2, and a latch and a through hole are provided in the upper movable part 4 or the lower movable part 5. The handle 11 connects to the latch through the through hole, controlling the latch to rotate so that it engages or disengages from the slot, thereby achieving the disengagement or installation of the upper movable part 4 and the lower movable part 5. In this embodiment, the hinge assembly of the upper fixed fixture and the hinge assembly of the lower fixed fixture are located on opposite sides, avoiding interference between the two handles 11 and affecting operation. Simultaneously, the upper cavity and the lower cavity are multiple sets in a one-to-one correspondence. That is, multiple sets of corresponding upper fixed half-grooves, upper movable half-grooves, lower fixed half-grooves, and lower movable half-grooves are provided to achieve simultaneous flipping and positioning of multiple workpieces 14 to be flipped, thereby effectively increasing production efficiency.

[0057] In this embodiment, the upper fixed part 3, the lower fixed part 2, the upper movable part 4, and the lower movable part 5 can be made of a single piece of stainless steel, ensuring processing accuracy while cooperating with the guide post. They are connected by nylon hinges 10, and the second end is locked by a fixed handle (with bolts) to secure the upper chuck 13 or the lower chuck. When opening, rotate the handle to pull open the fixture and place the upper chuck 13, the lower chuck, and the product. When closing, rotate the handle in the opposite direction to lock and fix it. The entire device greatly reduces the difficulty of operation, simplifies the action, and improves work efficiency. The nylon hinge 10 can be made of high-precision, heavy-duty industrial materials to ensure its service life. The chuck fixing position can be designed with an installation structure according to the type of chuck used in different equipment, thereby matching the equipment used.

[0058] The flipping alignment device disclosed in some embodiments of the present invention, based on the above embodiments, such as... Figure 1 As shown, to achieve the raising or lowering of the lower fixing fixture, the lifting assembly is implemented using a manual positioning method. It includes a support assembly, a movable rod, an eccentric wheel 8, and a rocker arm 9. The support assembly is fixed to the base 1, the movable rod is rotatably mounted on the support assembly, the eccentric wheel 8 is fixed to the movable rod, and the bottom end of the lower fixing fixture is supported on the eccentric wheel 8. The rocker arm 9 is mounted on one end of the movable rod to drive its rotation. In this embodiment, the support assembly consists of two positioning blocks arranged side-by-side below the upper fixing fixture. Through holes are provided on the two positioning blocks, through which the movable rod passes. The eccentric wheel 8 is fitted and fixed to the movable rod near the two positioning blocks. One end of the movable rod extends out of the base 1 and is fitted with the rocker arm 9. The rocker arm 9 controls the rotation of the movable rod, thereby driving the eccentric wheel 8 to rotate, thus raising or lowering the fixing fixture. In this embodiment, a manual eccentric wheel 8 power device is used. By manually pressing down the rocker arm handle, the eccentric wheel 8 rotates along the central axis, thereby lifting the sliding seat and providing power for the entire alignment action. It should be noted that lifting and lowering can also be achieved by hydraulic lifting or cylinder lifting. These lifting methods require the use of other components, have more complex structures, and higher equipment costs, but they should all be within the scope of protection of this application and will not be elaborated here.

[0059] The flipping alignment device disclosed in some embodiments of the present invention, based on the above embodiments, such as... Figures 1 to 3 As shown, the guide post includes a positioning post 7 and two parallel guide posts 6; there are three upper sliding holes and three lower sliding holes, which are respectively fitted onto the positioning post 7 and the two guide posts 6; and the positioning assembly can position the upper fixing fixture at different heights on the positioning post 7. The positioning post 7 can be square, or two can be provided to connect to the upper fixing fixture near both ends to ensure balance. The guide post can be cylindrical, with multiple positioning holes of different heights provided on the square positioning post 7. At the same time, a fixing hole is opened in the upper sliding hole fitted onto the positioning post 7, extending laterally to the side wall of the upper fixing fixture. A pin 12 passes through the fixing hole and is inserted into the appropriate positioning hole to meet the positioning requirements of the workpiece 14 to be flipped at different heights. The guide post can be fixed to the base 1 using a round pressure plate and hexagon socket head cap screws to ensure no shaking during up-and-down sliding. The guide post 6 can be a standard part made of finished alloy steel to improve its service life. The positioning post 7 needs to be installed perpendicular to the base 1. The thickness of the base 1 must be greater than or equal to twice the diameter of the positioning post 7 to ensure the reliability of the guide post. The square guide post can be made of a high-hardness quenched material with a surface hardness of HRC62 or higher. It needs to be made of a different material and have a different hardness than the upper and lower fixing fixtures to avoid burning the surface of the insert material after sliding for a long time, which would render it unusable.

[0060] In this embodiment, there can be three positioning holes, and three gear adjustment keyways (positioning holes) are set. An identical keyway (fixing hole) is designed on the outer side of the upper slide, so that different gear heights can be fixed by using the positioning key pin 12, which can adapt to products of different heights; breaking the limitation of customized heights and making the entire device more versatile.

[0061] In this embodiment, a set of guiding devices (guide posts 6) is set on the plane of the base 1 to make the overall movement smooth and effortless; at the same time, two precision positioning square guide posts (positioning posts 7) are erected on the base 1 to ensure that the entire device has higher precision and is more durable; the entire invention device has a simple and clear structure, is easy to operate, and has a low manufacturing cost.

[0062] The flipping alignment device disclosed in some embodiments of the present invention, based on the above embodiments, includes an upper clamp 13 comprising a T-shaped positioning part, a connecting part, and a first clamping head, wherein the small end of the T-shaped positioning part is connected to the first clamping head through the connecting part, and the outer diameter of the first clamping head is larger than the outer diameter of the connecting part and the large end of the T-shaped positioning part; the upper movable part 4 protrudes from its lower part on the side near the upper fixed part 3 to form a first step; the lower part of the upper fixed part 3 protrudes from its upper part on the side near the upper movable part 4 to form a second step that can engage with the first step; the upper movable half-groove... Includes: a first groove located on the upper part of the upper movable part 4 and adapted to the large end of the T-shaped positioning part; a second groove adapted to the small end of the T-shaped positioning part; a third groove adapted to the connecting part; and a fourth groove located on the lower part of the upper movable part 4 and adapted to the first clamping head; the upper fixed half groove is located on the lower part of the upper fixed part 3 and adapted to the first clamping head; the groove depth of the first, second, and third grooves is greater than the outer diameter of the T-shaped positioning part and the connecting part, so that the fourth groove and the upper fixed half groove form a cavity adapted to the first clamping head after docking. The structure of the lower clamping head can be the same as that of the upper clamping head 13. Correspondingly, the structures of the lower fixed part 2 and the lower movable part 5 are also the same as those of the upper fixed part 3 and the upper movable part 4 and are arranged symmetrically.

[0063] The flipping alignment device disclosed in some embodiments of the present invention, based on the above embodiments, may have a different structure for the lower clamp than for the upper clamp 13. Specifically, the lower clamp includes a columnar tail and a second clamping head connected together, the outer diameter of the columnar tail being smaller than the outer diameter of the second clamping head; the lower movable part 5 protrudes from the upper part on the side near the lower fixed part 2 to form a third step; the lower fixed part 2 protrudes from the lower part near the lower movable part 5 to form a fourth step that can engage with the third step; the lower movable half groove includes: an insertion hole extending downward from the lower upper end of the lower movable part 5 and adapted to the columnar tail, and a sixth groove located on the upper part of the lower movable part 5 and adapted to the second clamping head; the lower fixed half groove is located on the upper part of the upper fixed part 3 and adapted to the second clamping head; the sixth groove and the lower fixed half groove are joined together to form a cavity adapted to the second clamping head.

[0064] The flipping and alignment device disclosed in some embodiments of the present invention, based on the above embodiments, further includes a heating component for heating the lower fixed fixture in order to facilitate the detachment of the workpiece 14 to be flipped from the lower chuck. The heating component can be a heating wire, which provides a reasonable heating temperature by setting an appropriate power to avoid damage to the lower chuck due to excessive temperature. The heating component is embedded in the lower fixed part 2 and is located near the lower movable part 5. Specifically, a through hole can be provided in the lower fixed part 2 near the lower movable part 5 to house the heating wire, which also facilitates replacement in case of heating wire failure. By heating the lower fixed fixture, the viscosity of the adhesive substance in the lower chuck located on the lower fixed fixture is reduced, thereby reducing the adhesion between the lower chuck and the workpiece 14 to be flipped. Meanwhile, the upper fixed fixture has a lower temperature, and the adhesive substance in the upper chuck 13 has a stronger viscosity, so that when the two come into contact, the workpiece 14 to be flipped can be adhered to by the adhesive substance in the upper chuck 13 and detached from the lower chuck.

[0065] Some embodiments of the present invention also disclose a flipping and alignment method, which uses the aforementioned flipping and alignment equipment. An adhesive material is applied to the upper mounting portion, and the workpiece 14 to be flipped is mounted in the lower mounting portion. A lower clamp is heated by a lower fixing fixture, and a lifting assembly lifts the lower fixing fixture, causing the upper end of the workpiece 14 to abut against the adhesive material in the upper mounting portion. The lower fixing fixture falls with the lifting assembly, and the workpiece to be flipped detaches from the lower clamp and is adhered to the upper mounting portion. This method is simple to operate, provides accurate and reliable positioning, and has good market application prospects.

[0066] Specifically, in some embodiments, the flipping alignment device is fully supported by the base 1, the guide post is fixed on the base 1, the upper fixing fixture and the lower fixing fixture are connected by the guide sleeve and the guide post (guide post 6) and can slide between each other; the square guide post (positioning post 7) ​​is also fixed on the base 1 and is used for precise positioning and guidance; in use, the upper fixing fixture and the positioning post 7 are first fixed by the pin 12 and kept stationary; while the lower fixing fixture is moved upward by the force generated by the rotation of the eccentric wheel 8 through the rocker arm handle (rocker arm 9); thus aligning and moving with the upper fixing fixture. Loosen the screws by rotating the handle and pull open the lower movable part 5. After pulling it open, four mounting positions (lower movable half-grooves) for installing the chucks on the inside will be exposed, used to place the lower chucks with the product attached. The upper movable half-grooves are designed by making the tail of the upper chuck 13 into a T-groove shape, so that the upper chuck 13 can be hung on the upper movable part 4. After the upper chuck 13 is installed, close the upper movable part 4 and lock the upper chuck 13 onto the upper fixed fixture by rotating the handle. The lower fixed fixture is designed by making the tail of the lower chuck into a cylinder, which fits into the round hole (insertion hole) on the lower movable part 5, so that the lower chuck can be placed on the lower movable part 5. After the lower chuck is installed, close the lower movable part 5 and lock the lower chuck onto the lower fixed fixture by rotating the handle. When the lower fixed fixture is aligned and closed with the upper fixed fixture by the eccentric power device, the chucks on the upper fixed fixture will hold the product, and then the chucks on the lower fixed fixture will release the product, thus completing the entire process of product alignment and flipping.
