However, each fixed carousel can only accommodate products of a certain size and quantity. If the type and size of the product changes, it is necessary to purchase a matching carousel. This method has the following disadvantages:

[0048] In order to solve the problem that each of the existing fixed turntables can only accommodate products of a specific size and quantity, and if the type and size of the product change, it is necessary to purchase a matching turntable, and it is impossible to adjust according to different product requirements and effectively cope with changes in products of different sizes, thus failing to meet changing production needs and having poor adaptability, the present invention provides an adjustable coating turntable, which aims to achieve flexible adaptation to products of different sizes by designing an adjustable positioning structure (positioning component) on the turntable, so as to overcome the shortcomings of the existing fixed turntable.

[0049] A coating rotating rack of the present invention comprises:

[0050] A frame body, which is provided with an upper turntable and a lower turntable;

[0051] A positioning assembly, comprising a first positioning assembly arranged on the upper turntable, and a second positioning assembly correspondingly arranged on the lower turntable; the first positioning assembly and the second positioning assembly are used to vertically clamp the hanging rod;

[0052] A plurality of the positioning components are arranged around the rotational direction of the frame, and among the plurality of the positioning components, at most 1 (0 or 1) the first positioning component is fixedly arranged, and the remaining first positioning components are configured to be able to slide around the rotational direction on the upper turntable to respective target positions and be tightened, and at most 1 (0 or 1) the second positioning component is fixedly arranged, and the remaining second positioning components are configured to be able to slide around the rotational direction on the lower turntable to respective target positions and be tightened.

[0053] The present invention enables the same turntable to adapt to changes in products of any different sizes, quantities and coating requirements simply by increasing or decreasing the number of positioning components and making corresponding position adjustments, so that products of different sizes can be loaded to maximize their loading capacity, and the demand for different turntables can be reduced to facilitate the adaptation of products of different sizes and the installation of different numbers of turntable rods (hanging rods), thereby reducing manufacturing and labor costs, saving space, and simplifying the operating process, thereby greatly improving the practicability of the turntable and better meeting changing production needs.

[0054] The invention also provides a coating device, a turntable adjustment tool and a turntable adjustment method.

[0055] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings.

[0056] refer to Figure 1 , Figure 3 and Figure 5 The coating rotating frame of the present invention comprises a frame body, a positioning assembly, a sliding guide mechanism and a fastening mechanism.

[0057] There are turntables at the upper and lower ends of the frame, including an upper turntable 1 (upper turntable) arranged on the top of the frame, and a lower turntable 2 (lower turntable) arranged on the bottom of the frame. The frame is arranged to be able to rotate horizontally around the rotation center. The upper turntable 1 and the lower turntable 2 are horizontally arranged on the frame.

[0058] There are multiple positioning components. Multiple positioning components are arranged around the rotational circumference of the frame. The rotational circumference is the circumferential direction of a circle with the rotation center of the frame as the center. Each positioning component includes a first positioning component 3 and a second positioning component 4. Among them, the first positioning component 3 is arranged on the top edge of the upper turntable 1, and the second positioning component 4 is arranged on the top edge of the lower turntable 2, and the first positioning component 3 and the second positioning component 4 of each positioning component are arranged in pairs up and down, and are used to vertically clamp the hanging rod 5 between the first positioning component 3 and the second positioning component 4. A clamp 51 is provided on the hanging rod 5 for hanging the processing object (product) to be coated.

[0059] In some embodiments, a plurality of positioning components are evenly arranged around the rotational circumference of the frame. Alternatively, a plurality of positioning components are unevenly arranged around the rotational circumference of the frame. When each positioning component is evenly arranged around the rotational circumference of the frame, the distance between any two adjacent hanging rods 5 clamped on each positioning component is consistent, and the size of the product hung on each hanging rod 5 is also consistent. When each positioning component is unevenly arranged around the rotational circumference of the frame, that is, the distance (arc angle) between one part of the positioning components in the circumferential direction is different from the distance (arc angle) between another part of the positioning components in the circumferential direction, and the distance between the corresponding hanging rods 5 clamped on the two parts of the positioning components is also different, then products with different sizes can be hung on the hanging rods 5 clamped by the two parts of the positioning components with the above-mentioned different distances. In addition, when the distance between the positioning components in the circumferential direction is larger, the size of the product hung on the hanging rod 5 is also larger, and vice versa.

[0060] Figure 1 The schematic diagram shows that 15 positioning components are evenly arranged on the frame ( Figure 1 , Figure 3 , Figure 5 and Figure 7-Figure 9 An example is shown in which a hanging rod 5 with a clamp 51 of an adapted size is vertically clamped on a positioning component, and the clamp 51 is used to hang products of corresponding size. Figure 2 The schematic diagram shows that 23 positioning components are evenly arranged on the frame ( Figure 2 and Figure 4 The number of positioning components shown in each of the examples is not limited to correspondence), and a fixture 51 with another smaller size (relative to Figure 1 ) is vertically clamped on a positioning assembly, and the clamp 51 is used to hang products with smaller sizes. Figure 2 The number of products that can be mounted on the rack in will be more than Figure 1 The number of products that can be mounted on the rack.

[0061] The following describes in detail the implementation of the present invention by taking the example that the positioning components are evenly arranged around the rotation circumference of the frame.

[0062] In some embodiments, the multiple first positioning components 3 of the multiple positioning components include one fixed first positioning component 3, and the remaining first positioning components 3 are configured to be able to slide around the rotational direction on the upper turntable 1 to their respective target positions and be tightened; and the multiple second positioning components 4 of the multiple positioning components include one fixed second positioning component 4, and the remaining second positioning components 4 are configured to be able to slide around the rotational direction on the lower turntable 2 to their respective target positions and be tightened.

[0063] refer to Figure 1 , Figure 3 and Figure 5 In some embodiments, each first positioning component 3 is evenly disposed on the top surface of the upper turntable 1, each second positioning component 4 is evenly disposed on the top surface of the lower turntable 2, and each first positioning component 3 corresponds to a second positioning component 4 below in vertical position.

[0064] Among them, each first positioning assembly 3 includes a fixed first fixed positioning assembly 31, and the rest are first sliding positioning assemblies 32 that can slide around the rotation circumference. Each second positioning assembly 4 includes a fixed second fixed positioning assembly 41, and the rest are second sliding positioning assemblies 42 that can slide around the rotation circumference. Figure 1 The number of the first sliding positioning components 32 and the second sliding positioning components 42 is 14 each). The first fixed positioning components 31 and the second fixed positioning components 41 correspond to each other up and down to form one positioning component, and the remaining first sliding positioning components 32 and the remaining second sliding positioning components 42 correspond to each other up and down to form the remaining positioning components.

[0065] In some other embodiments, the upper and lower positions of the first fixed positioning component and the second fixed positioning component do not need to correspond, that is, the first fixed positioning component can be paired with the second sliding positioning component corresponding to a position below to form a positioning component, and the second fixed positioning component can be paired with the first sliding positioning component corresponding to a position above to form another positioning component. For ease of description, in the following embodiments, the first fixed positioning component 31 and the second fixed positioning component 41 corresponding to each other from top to bottom will be used as an example for explanation.

[0066] In some embodiments, the sliding guide mechanism includes a guide rail. The guide rail includes a first guide rail 9 arranged on the top surface of the upper turntable 1, such as Figure 5 As shown, and the annular second guide rail 7 provided on the top surface of the lower turntable 2, as shown Figure 3 As shown. The first guide rail 9 is used to provide guidance for the first sliding positioning assembly 32 when sliding along the circumferential direction; the second guide rail 7 is used to provide guidance for the second sliding positioning assembly 42 when sliding along the circumferential direction. In this way, it can be ensured that all the first sliding positioning assemblies 32 and the second sliding positioning assemblies 42 can be aligned with the rotation center when sliding, so that the operation is smooth and the position is accurate.

[0067] Among them, the position of the first fixed positioning component 31 is used as the reference position (0 degree angle position on the circumference), and the first sliding positioning component 32 uses the position of the first fixed positioning component 31 as the positioning reference reference to determine the setting position (circumferential angle position) in the rotation circumference, and then moves to the setting position along the first guide rail 9 and is fastened to the upper turntable 1. Similarly, the position of the second fixed positioning component 41 is used as the reference position (0 degree angle position on the circumference), and the second sliding positioning component 42 uses the position of the second fixed positioning component 41 as the positioning reference reference to determine the setting position (circumferential angle position) in the rotation circumference, and then moves to the setting position along the second guide rail 7 and is fastened to the lower turntable 2. In this way, the accuracy of adjustment can be ensured and the adjustment control level can be improved.

[0068] For example, when it is determined that four hanging rods 5 can be arranged on the turntable based on a product of a certain size, four positioning components are correspondingly arranged on the turntable, and the positions of a first fixed positioning component 31 and a second fixed positioning component 41 are used as the 0 degree angle position on the circumference, and the three first sliding positioning components 32 and the three second sliding positioning components 42 are sequentially spaced 90 degrees apart to determine their respective setting positions in the rotating circumferential direction, and are correspondingly moved along the first guide rail 9 and the second guide rail 7 to their respective setting positions (target positions), and then respectively fastened to the upper turntable 1 and the lower turntable 2, thereby 4 positioning components evenly distributed at a circumferential angle of 90 degrees are arranged in the circumferential direction. When it is determined that five hanging rods 5 can be arranged on the rotating frame according to another size of product, five positioning components are correspondingly arranged on the rotating frame, and the positions of one first fixed positioning component 31 and one second fixed positioning component 41 are used as the 0 degree angle position on the circumference, and the four first sliding positioning components 32 and the four second sliding positioning components 42 are arranged at intervals of 72 degrees in sequence, and their respective setting positions on the rotating circumference are determined, and they are moved to their respective setting positions along the first guide rail 9 and the second guide rail 7, and then fastened to the upper turntable 1 and the lower turntable 2, respectively, so that five positioning components are evenly distributed at a circumferential angle of 72 degrees are arranged on the circumference. And so on.

[0069] Traditional turntables are fixed. In order to accommodate products of different sizes and specifications, different types of turntables are usually required. Each turntable can only accommodate products of a specific size and quantity. If the type and size of the product changes, a matching turntable is required. The disadvantage of this fixed turntable is that it takes up a lot of storage and operation space, increases the burden of warehousing and transportation, and leads to an increase in various costs. The process of replacing the turntable is time-consuming and labor-intensive, which increases the operation time and labor costs, and also reduces production efficiency. In addition, the traditional fixed turntable cannot adjust the position of the hanging rod according to product requirements, cannot meet the changing production needs, and has poor flexibility and adaptability.

[0070] The coating turret of the present invention uses a fixed positioning component as a position adjustment reference, and sets other positioning components to be able to move to any position along the circumferential direction, and then fasten them after the setting position is determined. It can be adjusted to any position according to products of different sizes to accommodate products of different sizes, quantities and coating requirements, so that the clamping position of the hanging rod 5 can be flexibly changed according to the needs of the product to be suitable for loading products of different sizes and to maximize its loading capacity. In this way, the demand for different turrets can be reduced to facilitate the adaptation of products of different sizes, and different numbers of hanging rods 5 (turret rods) can be installed accordingly to achieve flexible adaptation to products of different sizes, thereby reducing manufacturing and labor costs, saving space, and simplifying the operation process. In addition, by making the positioning components unevenly distributed on the frame, at least two products of different sizes can be hung on the same turret, further improving the versatility of the turret.

[0071] refer to Figure 1 , Figure 3 and Figure 5 In some embodiments, the first fixed positioning component 31 is fixed on the top edge of the upper turntable 1. The second fixed positioning component 41 is supported on the top edge of the lower turntable 2 and extends to the top surface of the second guide rail 7 and is fixed thereto.

[0072] A first fastening mechanism is provided on the top surface of the upper turntable 1 for fastening the first sliding positioning assembly 32 after sliding to the respective target positions. A second fastening mechanism is provided on the top surface of the lower turntable 2 for fastening the second sliding positioning assembly 42 after sliding to the respective target positions.

[0073] In some embodiments, the first positioning assembly 3 and the second positioning assembly 4 include a support portion and a positioning portion. The support portion is used to connect with the turntable, and the positioning portion is connected to the support portion. The first positioning assembly 3 and the second positioning assembly 4 clamp the upper and lower ends of the installed hanging rod 5 through their respective positioning portions.

[0074] Among them, the positioning part of the first fixed positioning component 31 is the same as the positioning part of the first sliding positioning component 32, and the positioning part of the second fixed positioning component 41 is the same as the positioning part of the second sliding positioning component 42; the supporting part of the first fixed positioning component 31 is the same as or different from the supporting part of the first sliding positioning component 32, and the supporting part of the second fixed positioning component 41 is the same as or different from the supporting part of the second sliding positioning component 42; the positioning part of the first positioning component 3 is different from the positioning part of the second positioning component 4, and the supporting part of the first positioning component 3 is different from the supporting part of the second positioning component 4.

[0075] In some embodiments, the first fixed positioning assembly 31 includes a connected first support portion 34 and a first positioning portion 33; the first sliding positioning assembly 32 includes a connected second support portion 35 and a first positioning portion 33; the second fixed positioning assembly 41 includes a connected third support portion 44 and a second positioning portion 43; the second sliding positioning assembly 42 includes a connected fourth support portion 45 and a second positioning portion 43.

[0076] In some embodiments, the annular first guide rail 9 is placed flat on the top surface of the upper turntable 1. The center of the annular shape of the first guide rail 9 is located at the rotation center of the frame.

[0077] The first support portion 34 is fixed to the top edge of the upper turntable 1 by screws, so that the first positioning portion 33 of the first fixed positioning assembly 31 is fixedly supported on the top edge of the upper turntable 1 by the first support portion 34 and extends laterally out of the edge of the upper turntable 1 .

[0078] In some embodiments, when the first guide rail 9 passes through the installation position of the first support portion 34, an avoidance gap may be provided. Figure 5 shown.

[0079] In some other embodiments, the first guide rail may be disconnected when passing the installation position of the first support portion. Alternatively, when the inner edge of the first support portion is located outside the outer side of the first guide rail, the first guide rail may not need to avoid the installation position of the first support portion.

[0080] The second support portion 35 is movably disposed on the top edge of the upper turntable 1. In addition, the second support portion 35 abuts against the outer side of the circular ring of the first guide rail 9 through the inner side. Figure 5 When the second support part 35 is moved along the first guide rail 9, a sliding fit is formed between the two, so that the second support part 35 has the function of a slider, so that the first positioning part 33 of the first sliding positioning assembly 32 is also slidably fitted on the outer side of the circular ring of the first guide rail 9 through the second support part 35, and is movably supported on the top surface of the upper turntable 1 through the second support part 35, and extends laterally out of the edge of the upper turntable 1.

[0081] The first fastening mechanism includes a first annular pressure plate 6 provided on the top surface of the upper turntable 1, and the center of the circle of the first pressure plate 6 is located at the rotation center of the frame. The inner end of the second support portion 35 is located below the first pressure plate 6, and is slidably fitted on the outer side of the annular shape of the first guide rail 9. An annular groove 61 is circumferentially provided on the top surface of the first pressure plate 6, and a first mounting hole 352 is correspondingly provided on the top surface of the second support portion 35 that is slidably fitted on the outer side of the annular shape of the first guide rail 9 below the annular groove 61. At this time, the distance between any point along the circumference of the annular groove 61 and the rotation center of the frame will be consistent with the distance between the first mounting hole 352 and the rotation center of the frame. In this way, by tightening the first fastener 62 (reference Figure 6 ) passes through the annular groove 61 and is screwed into the first mounting hole 352, so that the second supporting portion 35 of the first sliding positioning assembly 32 can be fastened to the top surface of the upper turntable 1 after sliding to the target position.

[0082] In some embodiments, the first fastener 62 includes a screw with a cap, and the first mounting hole 352 corresponds to a screw hole.

[0083] The first pressing plate 6 can be installed on the first guide rail 9 and the upper turntable 1 .

[0084] In some embodiments, the first pressing plate 6 can be disconnected when passing through the installation position of the first supporting portion 34, and the disconnected end is fastened to the top surface of the upper turntable 1 to serve as a supporting foot of the first pressing plate 6, such as Figure 3 When the annular groove 61 is disconnected at both sides of the first support portion 34, the circumferential length of the annular groove 61 should meet the minimum setting distance requirement between the first support portion 34 and one of the adjacent second support portions 35 on both sides.

[0085] In some other embodiments, the first pressing plate may be provided with an avoidance gap when passing through the installation position of the first supporting portion. Alternatively, the first pressing plate may also cover the first supporting portion when passing through the installation position of the first supporting portion.

[0086] In some embodiments, the first pressure plate 6 is engaged with the second support portion 35 to limit the radial movement of the first sliding positioning assembly 32 along the upper turntable 1 .

[0087] In some embodiments, a block 351 is protruding from the top surface of the second support portion 35. Figure 5 As shown, a buckle protruding downward is provided on the outer side of the circular ring of the first pressing plate 6 along the circumferential direction. When the first pressing plate 6 covers the second supporting portion 35, the buckle is on the side away from the rotation center of the frame, that is, on the outer side of the clamping block 351, blocking the clamping block 351. Thus, through the clamping connection between the buckle and the clamping block 351, the second supporting portion 35 is restricted within the first pressing plate 6, and cannot be separated from the first pressing plate 6 and escape to the outer side of the upper turntable 1.

[0088] refer to Figure 3 In some embodiments, the annular second guide rail 7 is placed flat on the top surface of the lower turntable 2, and the center of the annular shape of the second guide rail 7 is located at the rotation center of the frame.

[0089] The third support portion 44 is supported on the edge of the top surface of the lower turntable 2 and extends to the top surface of the second guide rail 7, and is fastened to the top surface of the second guide rail 7 by screws, so that the second positioning portion 43 of the second fixed positioning assembly 41 is supported on the edge of the top surface of the lower turntable 2 through the third support portion 44, and is fixed on the top surface of the second guide rail 7, and extends laterally out of the edge of the lower turntable 2.

[0090] When the second guide rail 7 passes through the installation position of the third support portion 44, the inner side can be further turned inward and extended, that is, the annular width of the second guide rail 7 here is wider than that of other parts, so as to facilitate the installation of the third support portion 44. Figure 3 shown.

[0091] In some other embodiments, the second guide rail is arranged in a circular ring with equal width, and the inner end of the third support portion is located between the inner diameter and the outer diameter of the second guide rail. In this way, when the second guide rail passes through the installation position of the third support portion, it is not necessary to increase the width of the circular ring at this location.

[0092] The fourth support portion 45 is movably supported on the top edge of the lower turntable 2 and abuts against the outer side of the circular ring of the second guide rail 7. When the fourth support portion 45 is moved along the second guide rail 7, a sliding fit is formed between the two, so that the fourth support portion 45 has the function of a slider. Therefore, the second positioning portion 43 of the second sliding positioning assembly 42 is also supported on the top edge of the lower turntable 2 through the fourth support portion 45, and is slidably fitted on the outer side of the circular ring of the second guide rail 7, and extends laterally out of the edge of the lower turntable 2.

[0093] Furthermore, the fourth support portion 45 also extends to straddle the top surface of the second guide rail 7 , and forms a sliding fit with both the outer side and the inner side of the circular ring shape of the second guide rail 7 .

[0094] In some embodiments, the second fastening mechanism includes a plurality of second mounting holes 71 distributed along the circumferential direction on the top surface of the second guide rail 7, and an arcuate groove 452 provided along the circumferential direction on the top surface of the second sliding positioning assembly 42. The distance between the arcuate groove 452 and the rotation center of the frame is equal to the distance between the second mounting hole 71 and the rotation center of the frame. In addition, the distribution density of the second mounting holes 71 satisfies that when the second sliding positioning assembly 42 slides to any position along the outer side of the circular ring of the second guide rail 7, at least one second mounting hole 71 is exposed below the arcuate groove 452. In this way, the fourth support portion 45 can be fastened to the top surface of the second guide rail 7 by passing the second fastener through the arcuate groove 452 from above and screwing it into the second mounting hole 71, so that the second sliding positioning assembly 42 is fastened to the top surface of the second guide rail 7 after sliding to the target position.

[0095] Therefore, through different forms of slot matching, the first sliding positioning assembly 32 and the top surface of the upper turntable 1 can be fastened at any set position in the circumferential direction, and the second sliding positioning assembly 42 and the top surface of the lower turntable 2 can be fastened at any set position in the circumferential direction. The slot matching method is adopted, so that the first sliding positioning assembly 32 and the second sliding positioning assembly 42 can be flexibly moved during position adjustment to adapt to different product quantities. When the product size changes and the quantity increases or decreases, it can be simply increased or decreased by adding or reducing the first sliding positioning assembly 32 and the second sliding positioning assembly 42 on the rotating frame and sliding them to a suitable angle, thereby expanding the load-bearing capacity and stability. The position of each first sliding positioning assembly 32 and the second sliding positioning assembly 42 can be freely adjusted, and after being fixed, stable support can be provided. This avoids the need to frequently replace the rotating frame, and only the circumferential angle and number of the first sliding positioning assembly 32 and the second sliding positioning assembly 42 need to be adjusted.

[0096] In some embodiments, a plurality of circles of second mounting holes 71 are distributed circumferentially on the top surface of the second guide rail 7, and a plurality of arc grooves 452 (for example, Figure 3 The two circles of second mounting holes 71 and the corresponding two arc-shaped grooves 452 are shown to enhance the fastening effect.

[0097] In some embodiments, the second fastener includes a screw with a cap, and the second mounting hole 71 corresponds to a screw hole.

[0098] The first support portion 34 to the fourth support portion 45 are locked in place by screws to achieve the function of stably supporting the product fixture 51 .

[0099] In some embodiments, a clamping groove 451 is provided on the bottom surface of the fourth support portion 45, and the clamping groove 451 is clamped on the outer side and the inner side of the circular ring of the second guide rail 7 to limit the radial movement of the fourth support portion 45 along the lower turntable 2. The fourth support portion 45 is slidably matched with the second guide rail 7 through the groove wall of the clamping groove 451, but preferably, the outer groove wall of the clamping groove 451 is slidably matched with the outer side of the circular ring of the second guide rail 7.

[0100] In some embodiments, the second fastening mechanism further includes a second pressure plate 8 in the shape of an annular ring disposed on the top surface of the lower turntable 2, and the center of the annular ring of the second pressure plate 8 is located at the rotation center of the frame. The second pressure plate 8 is disposed on the inner end of the fourth support portion 45 to limit the inner end of the fourth support portion 45 close to the rotation center of the frame, which may warp up when the outer end is under greater pressure (from the weight of the product). The second pressure plate 8 can lightly touch the top surface of the inner end of the fourth support portion 45 to a degree that does not affect the smooth sliding of the fourth support portion 45.

[0101] In some embodiments, the second pressure plate 8 is disconnected on both sides of the third support portion 44, but the annular length of the second pressure plate 8 should meet the minimum setting distance requirement between the third support portion 44 and one adjacent fourth support portion 45 on both sides, so as to be able to achieve the pressing of all fourth support portions 45.

[0102] In some other embodiments, the second pressing plate 8 is a closed circular ring without a break, and can be pressed on the inner end of the third supporting portion 44 .

[0103] The second pressing plate 8 can be fastened to the top surface of the lower turntable 2 within the inner diameter of the second guide rail 7 .

[0104] On the rotating rack of the present invention, each positioning component that can slide can slide and adjust its position within a certain range. This design allows the positioning components to be flexibly moved during assembly to adapt to different numbers of products. As the number of products increases due to changes in product size, more positioning components can be added to the rotating rack to expand the load-bearing capacity and stability. The positioning components are fixed with screws to ensure that they remain stable when bearing loads. The rotating rack achieves adaptability to changes in product size through sliding adjustment of the positioning components. When the number of products increases or decreases due to changes in product size, the positioning components on the rotating rack can be simply increased or decreased, and they can be positioned at a suitable angle to accommodate more products.

[0105] refer to Figure 3 and Figure 6 In some embodiments, the first positioning portion 33 of the first fixed positioning component 31 is vertically rotatably disposed on the first support portion 34, and the first positioning portion 33 of the first sliding positioning component 32 is vertically rotatably disposed on the second support portion 35. Taking the cooperation between the first positioning portion 33 of the first sliding positioning component 32 and the second support portion 35 as an example, Figure 6 As shown, the inner side end of the first positioning part 33 of the first sliding positioning assembly 32 can be rotatably connected with the second support part 35 through a horizontal rotation axis, and further connected to the upper turntable 1 through the second support part 35. In this way, the first positioning part 33 of the first sliding positioning assembly 32 can rotate up and down around the rotation axis on the upper turntable 1, and can be Figure 6 (b) The vertical position shown is rotated downward to Figure 6 In the horizontal state shown in (a), the upper end of the hanging rod 5 is pressed so that the upper and lower ends of the hanging rod 5 can be clamped together with the second positioning part 43 of the corresponding second sliding positioning assembly 42 on the lower turntable 2, and the loading and unloading of the hanging rod 5 is convenient.

[0106] In some embodiments, a first clamping portion 331 is provided on the bottom surface of the outer end of the first positioning portion 33. Figure 5 and Figure 6 The first clamping portion 331 is used to press against the upper end of the hanging rod 5 to clamp when the first positioning portion 33 rotates to a horizontal state.

[0107] In some embodiments, a second clamping portion 431 is provided on the top surface of the second positioning portion 43 of the second positioning assembly 4. Figure 3 The second clamping portion 431 is used to support the lower end of the hanging rod 5 so as to clamp the upper and lower ends of the hanging rod 5 together with the first clamping portion 331 .

[0108] The center of the first clamping portion 331 on the first positioning portion 33 of each first positioning component 3 is located on the circumference of the same horizontal circle with the rotation center as the center, and the center of the second clamping portion 431 on the second positioning portion 43 of each second positioning component 4 is located on the circumference of the same horizontal circle with the rotation center as the center, and each first clamping portion 331 and each second clamping portion 431 are arranged one by one in the vertical direction.

[0109] In some embodiments, the first clamping portion 331 includes a limit bearing built into the bottom surface of the outer end of the first positioning portion 33, which is used to allow the limit bearing to be buckled into the upper end of the hanging rod 5 to form a clamping fit after the first positioning portion 33 is flipped downward.

[0110] In some embodiments, the second positioning portion 43 includes a supporting bearing 432 and a hollow pin shaft vertically arranged on the supporting bearing 432. The hollow pin shaft serves as the second clamping portion 431. The supporting bearing 432 of the second positioning portion 43 of the second fixed positioning assembly 41 is installed on the third supporting portion 44, and the supporting bearing 432 of the second positioning portion 43 of the second sliding positioning assembly 42 is installed on the fourth supporting portion 45.

[0111] The hollow pin (second clamping portion 431) may be, for example Figure 3The one shown has a support hole on the top and a pin with a U-shaped groove on the side. When installing the hanging rod 5, the lower end of the hanging rod 5 is matched in the support hole of the pin, and a limit pin is transversely provided on the lower end of the hanging rod 5. The limit pin falls into the U-shaped groove, which can limit the rotation of the hanging rod 5 relative to the support bearing 432.

[0112] refer to Figure 1 , Figure 7-Figure 9 In some embodiments, a baffle is further provided on the top surface area and the outer side of the lower turntable 2. The baffle is used to shield the lower turntable 2 from the top and the outer side, but the second clamping portion 431 provided on the top surface of the second positioning portion 43 needs to be exposed.

[0113] In some embodiments, the baffles include a first baffle 10 , a second baffle 11 , a third baffle 12 , and a fourth baffle 13 .

[0114] The number of the first baffles 10 is consistent with the number of the second positioning components 4, and the first baffles 10 are covered on the second positioning portion 43. Figure 7 A first through hole is provided on the top surface of the first baffle plate 10 for the top of the second clamping portion 431 to pass through. A second baffle plate 11 is hung between any two adjacent first baffle plates 10 on the second positioning portions 43. Figure 8 The third baffle 12 covers the top surface area of ​​the lower turntable 2 inside the first baffle 10 and the second baffle 11; the fourth baffle 13 covers the side area of ​​the lower turntable 2 outside the first baffle 10 and the second baffle 11, as shown. Fig. 9 shown.

[0115] In some embodiments, the shapes of the first baffle plate 10 and the second baffle plate 11 include an inverted groove shape having an opening along the rotation circumference.

[0116] In some embodiments, a third mounting hole 434 is provided on the top surface of the second positioning portion 43 (see Figure 3 ), a fourth mounting hole 103 is correspondingly provided on the top surface of the first baffle 10. The first baffle 10 is connected to the second positioning portion 43 by passing a third fastener 433 (cap screw) through the fourth mounting hole 103 from above and screwing it into the third mounting hole 434.

[0117] In some embodiments, the top surface of the first baffle plate 10 is provided with hanging pins 101 on both sides of the circumference, and the second baffle plate 11 is provided with hanging holes 111 on both sides of the circumference. The second baffle plate 11 is hung between two adjacent first baffle plates 10 through the cooperation between the hanging holes 111 and the hanging pins 101. The first baffle plate 10 and the second baffle plate 11 are alternately hung with each other to form a continuous ring, covering each second positioning portion 43, and only exposing the second clamping portion 431.

[0118] In some embodiments, the third baffle 12 is annular (can be formed by splicing multiple sections), and a fifth mounting hole 81 (screw hole) is provided on the top surface of the second pressing plate 8 (refer to Figure 3 ), a sixth mounting hole 121 (through hole) is correspondingly provided on the top surface of the third baffle 12, and the third baffle 12 is connected to the second pressure plate 8 by passing the fourth fastener (cap screw) through the sixth mounting hole 121 from above and screwing it into the fifth mounting hole 81.

[0119] In some embodiments, the fourth baffle 13 is a circular ring with the top bent inward (which can be formed by splicing multiple sections), and a seventh mounting hole 453 (screw hole) is provided on the outer end of the fourth support portion 45 (refer to Figure 3 , Figure 8 ), an eighth mounting hole 131 (waist-shaped hole) is correspondingly provided on the bent top of the fourth baffle 13, and the fourth baffle 13 is connected to the fourth support portion 45 by passing the fifth fastener (cap screw) through the eighth mounting hole 131 from above and screwing it into the seventh mounting hole 453.

[0120] In some embodiments, the hanging hole 111 on the second baffle plate 11 is a waist-shaped hole arranged along the circumferential direction to facilitate the hanging of the hanging pin 101 on the first baffle plate 10, and after hanging, the second baffle plate 11 is locked by horizontally inserting the pin 104 into the pin hole at the upper end of the hanging pin 101.

[0121] In some embodiments, on the first baffle plate 10, anti-collision pins 102 are provided on the top surface of the second positioning assembly 4 on both sides of the second clamping portion 431 in the oblique direction along the circumferential direction. When the second baffle plate 11 uses a waist-shaped hanging hole 111 with a certain length, when it reciprocates along the circumferential direction after hanging, the anti-collision pins 102 can be used to prevent the second baffle plate 11 from hitting the second clamping portion 431, and prevent the second baffle plate 11 from contacting the working fixture 51, which will affect the coating effect.

[0122] The above-mentioned baffles can provide a shielding area to prevent the film from being plated onto the frame (lower turntable 2) of the rotating frame, thereby providing a shielding area. In this way, only the baffles need to be maintained each time maintenance is performed, which reduces the maintenance of the rotating frame and improves the utilization efficiency of the rotating frame.

[0123] In some embodiments, a cover plate 17 is provided on the top surface of the frame. Figure 1 ( Figure 4 The cover plate 17 can be installed on the first pressing plate 6 or the upper turntable 1, and the annular groove 61 on the first pressing plate 6 is exposed.

[0124] In some embodiments, a bracket 18 is provided on the bottom of the frame for carrying the rotating frame. Figure 1 shown.

[0125] refer to Figure 2 and Figure 4 In some embodiments, the first guide rail (not shown) is configured as a closed annular ring, and each first positioning assembly 3 of the plurality of positioning assemblies is configured to be able to slide along the first guide rail on the upper turntable 1 in the rotational circumferential direction until sliding to the respective target positions on the circumference and being fastened. That is, the above-mentioned first fixed positioning assembly 31 is not provided in each first positioning assembly 3, or the above-mentioned first fixed positioning assembly 31 is also configured to be able to slide on the upper turntable 1 in the rotational circumferential direction, so that each first positioning assembly 3 becomes the first sliding positioning assembly 32 in the above-mentioned embodiment.

[0126] Correspondingly, the first pressing plate 6 is also configured as a closed annular shape to be engaged with and fastened to all the first sliding positioning components 32 .

[0127] In some embodiments, the second guide rail 7 is set to be a closed annular shape, and the width of the annular shape of the second guide rail 7 is consistent at all places, and each second positioning assembly 4 of the plurality of positioning assemblies is set to be able to slide along the second guide rail 7 on the lower turntable 2 around the rotation circumference until sliding to the respective target positions on the circumference and fastening. That is, the above-mentioned second fixed positioning assembly 41 is not set in each second positioning assembly 4, or the above-mentioned second fixed positioning assembly 41 is also set to be able to slide on the upper turntable 1 around the rotation circumference, so that each second positioning assembly 4 becomes the second sliding positioning assembly 42 in the above-mentioned embodiment.

[0128] Correspondingly, the second pressing plate 8 is also configured to be a closed annular shape to cover the inner ends of all the second sliding positioning assemblies 42 .

[0129] Figure 2 Parts A and B in the middle show the Figure 1 The comparison effect after the first fixed positioning assembly 31 and the second fixed positioning assembly 41 are replaced by the first sliding positioning assembly 32 and the second sliding positioning assembly 42 is shown in FIG. Figure 4 Parts C and D in the middle show the Figure 3 The comparison effect after the first fixed positioning assembly 31 and the second fixed positioning assembly 41 are replaced by the first sliding positioning assembly 32 and the second sliding positioning assembly 42 is shown in FIG. In this example, it is necessary to first determine one of the first sliding positioning assembly 32 and the second sliding positioning assembly 42 as the 0 degree reference and tighten it, for example, Figure 2 The first sliding positioning assembly 32 and the second sliding positioning assembly 42 in the A part and the B part are used as the 0 degree reference and tightened, and then on this basis, the other first sliding positioning assemblies 32 and the second sliding positioning assemblies 42 are adjusted to be at the target position. The position of the first first sliding positioning assembly 32 and the second sliding positioning assembly 42 can be determined by setting a 0 degree reference scale on the upper turntable 1 and the lower turntable 2. Figure 1 , Figure 3 , Figure 5-Figure 9 The other structures of the embodiments may be the same, please refer to the above embodiments for understanding.

[0130] A coating device of the present invention includes a coating chamber, in which the coating turret of the present invention is provided. When in use, first determine the appropriate number of hanging rods 5 that can be used on the turret according to the size of the product. Then, according to the determined number of hanging rods 5, configure a corresponding number of positioning components on the frame of the turret, and adjust the setting position (target position) of each positioning component on the frame. Next, load the product onto the clamp 51 of the hanging rod 5, and clamp the hanging rod 5 onto the positioning component of the turret, and then the turret can be set in the coating chamber to perform the required coating process.

[0131] A turret adjustment tool and a turret adjustment method of the present invention are described in detail below through specific implementation modes and in conjunction with the accompanying drawings.

[0132] A rotating frame adjustment tool of the present invention is used to be arranged on the above-mentioned Figure 1 (and combined with Figure 3 )or Figure 2 (and combined with Figure 4 ) of the present invention, the relative positions of any two adjacent positioning components on a coating rotary rack are adjusted and determined.

[0133] The following is a rotating frame adjustment tool of the present invention, which is used for adjusting the rotation of the rotating frame. Figure 1 and Figure 3 The position adjustment of a positioning assembly on a coating rotating rack of the present invention is described as an example.

[0134] A rotating frame adjustment tool of the present invention can be used to determine and fix the setting position of the first sliding positioning component 32 relative to the first fixed positioning component 31.

[0135] refer to Fig.10 Combined with reference Figure 1 and Figure 3 In some embodiments, the adjustment tool includes a first sector block 14, such as Fig.10 (a), and the second sector block 15, as shown in Fig.10 (b) as shown. Figure 3The working position states of the first sector block 14 and the second sector block 15 are shown in FIG. Among them, the first sector block 14 is used to adjust and determine the relative position between any two adjacent first positioning components 3. Since the first fixed positioning component 31 is fixedly set, the first sector block 14 is actually used to determine the setting position of each first sliding positioning component 32 in the circumferential direction of the upper turntable 1. The second sector block 15 is used to adjust and determine the relative position between any two adjacent second positioning components 4. Similarly, since the second fixed positioning component 41 is fixedly set, the second sector block 15 is actually used to determine the setting position of each second sliding positioning component 42 in the circumferential direction of the lower turntable 2.

[0136] In some embodiments, the first sector 14 and the second sector 15 have the same predetermined arc angle.

[0137] In some embodiments, the second fan-shaped block 15 is provided with protruding ears 151 on both ends, which are used to overlap the relative edges of the top surfaces of the supporting parts of the two adjacent second positioning components 4 through the ears 151 when adjusting the relative position between the two adjacent second positioning components 4, so as to increase the stability of the second fan-shaped block 15.

[0138] In some embodiments, when the first sector block 14 is used, the circumferential edge of the upper turntable 1 is used as the arc positioning reference so that the center of the circle corresponding to the arc of the first sector block 14 coincides with the rotation center of the frame. To this end, a downward turning structure is set on the outer side of the arc of the first sector block 14 to form a sector turning portion 141. In this way, the first sector block 14 can use the inner side surface of the sector of the turning portion 141 as a reference surface for abutting and matching with the edge of the upper turntable 1. The two ends of the first sector block 14 along the circumferential direction are used to abut between two adjacent first positioning components 3. In this way, when the position of one of the two adjacent first positioning components 3 is fixed, the position of the other one is also determined and can be tightened. For example, when the first first sliding positioning assembly 32 adjacent to the first fixed positioning assembly 31 is to be installed, the position of the fixed first fixed positioning assembly 31 is used as the 0-degree angle reference in the rotation circumferential direction, and one end (left end) of the first sector block 14 is pressed against the side surface of the first support portion 34 as the reference, and the inner side of the turning portion 141 on the first sector block 14 is pressed against the edge of the circular upper turntable 1; then, the first adjacent first sliding positioning assembly 32 is slid through the second support portion 35 to make the second support portion 35 press against the other end (right end) of the first sector block 14, that is, the installation position (circumferential angle position on the circumference) of the first first sliding positioning assembly 32 is determined and fastened. Next, the first first sliding positioning assembly 32 (second support portion 35) after being fastened is used as the new reference, and the same method as above is used to determine the position and fasten the second first sliding positioning assembly 32, and so on.

[0139] In some embodiments, when the second sector block 15 is used, the inner side surface of the arc of the second sector block 15 is directly used as a reference surface for abutting against the outer side of the annular second guide rail 7, so that the center of the circle corresponding to the arc of the second sector block 15 coincides with the rotation center of the frame. The two ends of the second sector block 15 along the circumferential direction are used to abut between two adjacent second positioning components 4. In this way, when the position of one of the two adjacent second positioning components 4 is fixed, the position of the other one is also determined and can be tightened. For example, when it is necessary to install the first second sliding positioning assembly 42 adjacent to the second fixed positioning assembly 41, the position of the fixed second fixed positioning assembly 41 is used as the 0-degree angle reference in the rotation circumferential direction, and one end (left end) of the second sector block 15 is pressed against the side surface of the third support portion 44 as the reference, and the inner side of the arc of the second sector block 15 is pressed against the outer side of the circular second guide rail 7; then, the adjacent first second sliding positioning assembly 42 is slid through the fourth support portion 45 to make the fourth support portion 45 press against the other end (right end) of the second sector block 15, that is, the installation position of the first second sliding positioning assembly 42 is determined and fastened. Next, the first second sliding positioning assembly 42 (fourth support portion 45) after being fastened is used as the new reference, and the same method as above is used to determine the position and fasten the second second sliding positioning assembly 42, and so on.

[0140] The arc angles of the first sector block 14 and the second sector block 15 match the products of corresponding sizes (i.e. corresponding to a certain number of hanging rods 5). For each size of product, the first sector block 14 and the second sector block 15 of the corresponding sector arc angle need to be configured. The size of the sector arc angle of the first sector block 14 and the second sector block 15 is inversely proportional to the number of hanging rods 5 to be installed. The more the number of hanging rods 5 to be installed, the smaller the sector arc angle of the first sector block 14 and the second sector block 15. At the same time, when determining the arc angles of the first sector block 14 and the second sector block 15, the widths of the first support portion 34, the second support portion 35, the third support portion 44 and the fourth support portion 45 in the circumferential direction need to be taken into account. The widths of the first support portion 34 and the second support portion 35 are preferably equal, and the widths of the third support portion 44 and the fourth support portion 45 are preferably equal.

[0141] In some embodiments, the first sector block 14 and the second sector block 15 are respectively provided with fine-tuning screws 16 .

[0142] Among them, the inner side surface (reference surface) of the sector-shaped turning portion 141 of the first sector block 14 and the two ends of the sector are respectively provided with fine-tuning screws 16 (the fine-tuning screws 16 on the inner side surface of the turning portion 141 are not shown). The inner side surface (reference surface) of the sector of the second sector block 15 and the two ends of the sector are respectively provided with fine-tuning screws 16. By adjusting the tightness of the fine-tuning screws 16 on the first sector block 14 and the second sector block 15 relative to the in and out positions of the first sector block 14 and the second sector block 15, it can be used to correct the processing error and matching error of the first sector block 14 and the second sector block 15, so as to eliminate the cumulative error that may be generated when installing the first sliding positioning assembly 32 and the second sliding positioning assembly 42.

[0143] When the turret adjustment tool is used to adjust e.g. Figure 2-Figure 4 When the positioning components on the rotating frame shown are adjusted and determined, the method is similar to the above embodiment. It is only necessary to first determine the position of one pair of the first positioning components 3 (first sliding positioning components 32) and the second positioning components 4 (second sliding positioning components 42) as the 0-degree reference and tighten them. For example, corresponding upper and lower 0-degree reference scales can be preset on the upper turntable 1 and the lower turntable 2, and the adjacent first sliding positioning components 32 and second sliding positioning components 42 are first slid to the position and tightened. On this basis, the above method is used to adjust the other positioning components so that the other first sliding positioning components 32 and second sliding positioning components 42 are each at the predetermined target position (circumferential angle position) on the circumference.

[0144] A turret adjustment method of the present invention is used to use the turret adjustment tool to adjust the turret. Figure 1 (and combined with Figure 3 )or Figure 2 (and combined with Figure 4 ) is used to adjust and determine the setting positions of each positioning component on a coating rotating rack shown in the figure on the rack body.

[0145] The following is a rotating frame adjustment method of the present invention, which is used for example Figure 1 and Figure 3 The position adjustment of a positioning assembly on a coating rotating rack of the present invention is described as an example.

[0146] refer to Figure 1 and Figure 3 In some embodiments, a turret adjustment method of the present invention includes:

[0147] Taking the first support portion 34 of the fixed first fixed positioning assembly 31 as the position reference, the left end of the first sector block 14 is pressed against the right side of the first support portion 34, and the inner side surface of the turning portion 141 provided on the first sector block 14 is pressed against the edge of the upper turntable 1. Then, the first first sliding positioning assembly 32 adjacent to the right side is slid to the left side through the second support portion 35 to press against the right end of the first sector block 14, and is tightened. Next, taking the second support portion 35 of the tightened first first sliding positioning assembly 32 as the new position reference, and using the same method as above, the positions of the second first sliding positioning assembly 32 adjacent to the first first sliding positioning assembly 32 and the subsequent first sliding positioning assembly 32 are adjusted, determined and tightened in turn.

[0148] Furthermore, taking the third support portion 44 of the fixed second fixed positioning assembly 41 as the position reference, the left end of the second sector block 15 is pressed against the right side of the third support portion 44, and the sector inner side surface of the second sector block 15 is pressed against the outer side of the second guide rail 7. Then, the first second sliding positioning assembly 42 adjacent to the right side is slid to the left side through the fourth support portion 45 to press against the right end of the second sector block 15, and is fastened. Next, taking the fourth support portion 45 of the first second sliding positioning assembly 42 after fastening as the new position reference, and using the same method as above, the positions of the second second sliding positioning assembly 42 adjacent to the first second sliding positioning assembly 42 and the subsequent second sliding positioning assembly 42 are adjusted, determined and fastened in turn.

[0149] The order of using the first sector block 14 and the second sector block 15 is not limited, but it is preferred to use the second sector block 15 to adjust and position the second sliding positioning assembly 42 first, and then, with the positioned second sliding positioning assemblies 42 as a reference, use the first sector block 14 to continue to adjust and position the first sliding positioning assembly 32. This is because the second positioning assembly 4 is a support member that is heavily pressed by the hanging rod 5, and the accuracy of its installation position is more important to ensure the quality of the coating. The first positioning assembly 3 is only freely pressed against the upper end of the hanging rod 5 during operation and is in a subordinate position, so the first positioning assembly 3 can be adjusted after the second sliding positioning assemblies 42 are adjusted and confirmed to be correct.

[0150] In the above method, the arc angles of the first sector block 14 and the second sector block 15 used are determined and processed according to the preset number of the hanging rods 5 .

[0151] In the above method, the error reflected in the adjustment process can also be corrected by adjusting the entry and exit positions of the reference surface of the first sector block 14 and the fine-tuning screws 16 provided on both ends, and by adjusting the entry and exit positions of the reference surface of the second sector block 15 and the fine-tuning screws 16 provided on both ends.

[0152] In summary, the present invention can reduce the demand for rotating racks of various specifications, because the same rotating rack can meet the requirements of product size changes by adjusting the number and position of the positioning components used to clamp the hanging rod. This flexible design greatly reduces the occupation of storage and production space, making the layout of the workplace more concise and effective. In addition, since it is no longer necessary to purchase rotating racks of various specifications, the cost of purchasing the rotating rack can be significantly reduced, so that only one adjustable rotating rack and a corresponding number of positioning components are required to meet the needs of products of various sizes, thereby reducing equipment investment and maintenance costs. Moreover, the present invention can directly perform sliding adjustment of the positioning component on the current rotating rack, avoiding the cumbersome replacement process, and the adjustment can be completed through simple sliding and locking operations, greatly improving production efficiency. Therefore, the present invention can quickly adapt to product changes of different sizes, flexibly respond to fluctuations in production demand, improve the practicality of the rotating rack, and well meet the changing production needs. Therefore, the present invention overcomes the limitations of the old rotating rack through the innovative adjustment design of the positioning component, and provides an efficient, economical, easy-to-operate and flexible rotating rack solution, which can be applied to the production scenarios of products of various sizes.

[0153] The above are only preferred embodiments of the present invention, and the embodiments are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made using the description and drawings of the present invention should be included in the protection scope of the present invention.
