Anti-wrinkle up and down feeding opening and closing device

Abstract

This utility model discloses an anti-wrinkle loading and unloading clamping device, relating to the field of electroplating fixture technology. The utility model includes an upper support part for supporting an upper plate; an upper clamping part for controlling the upper clamping assembly; a lower support part for supporting a lower plate; and a lower clamping part for controlling the lower clamping assembly. The upper and lower clamping parts have identical structures, each including a pushing mechanism and a push plate. The horizontal height of the middle and sides of the contact surface between the push plate and the clamps is inconsistent, forming at least two height differences. This utility model uses the pushing mechanism to first prevent the middle area of ​​the push plate surface from contacting the clamps of the upper and lower clamping assemblies, thus closing the middle clamp of the upper and lower clamping assemblies of the electroplating fixture. After the middle clamping area provides initial support for the electroplated material, it then prevents the sides of the push plate surface from contacting the clamps of the upper and lower clamping assemblies, closing the remaining clamps of the upper and lower clamping assemblies of the electroplating fixture. This effectively avoids the wrinkling problem caused by the material sagging under its own weight in traditional synchronous clamping methods.

Description

Technical Field

[0001] This utility model belongs to the field of electroplating fixture technology, and specifically relates to an anti-wrinkle loading and unloading clamping device. Background Technology

[0002] In the electroplating process, sheet metal needs to be clamped by fixtures for processing. Currently, the industry standard practice is to open the upper and lower clamps of the fixture simultaneously during loading, then place the sheet metal into the fixture, and finally release the fixture so that the upper and lower clamps hold the sheet metal together. Currently, there is no readily adaptable automatic clamping device for the fixture, making it difficult to meet the high-efficiency requirements of automated production. More importantly, the existing simultaneous clamping method has significant drawbacks: due to the sheet metal's own weight, when the upper and lower clamps are open simultaneously and the sheet metal is not stably clamped, the sheet metal is prone to wrinkling due to gravity. This not only affects the processing accuracy and product quality but may also lead to uneven plating in subsequent electroplating processes, severely restricting production efficiency and product qualification rate.

[0003] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an anti-wrinkle loading and unloading clamping device for electroplating fixtures. The electroplating fixture includes an upper plate, an upper clamping assembly, a lower plate, and a lower clamping assembly. The upper and lower clamping assemblies are used to clamp the upper and lower ends of the electroplating sheet.

[0005] Upper support section, used to support the upper plate;

[0006] An upper-opening clamping part is provided corresponding to the upper support part, and the upper-opening clamping part is used to control the upper clamping assembly;

[0007] The lower support section is used to support the lower plate;

[0008] The lower clamping part is provided in correspondence with the lower support part, and the lower clamping part is used to control the lower clamping assembly;

[0009] The upper and lower clamping parts have the same structure, both including a pushing mechanism and a push plate. The upper and lower clamping groups are composed of multiple clamps. The pushing mechanism is used to drive the push plate to contact the clamps in order to control the clamps to open and close. The horizontal height of the middle and the sides of the contact surface between the push plate and the clamp is not the same, forming at least two layers of height difference, so that the middle of the push plate surface will leave the clamps first compared to the sides.

[0010] Both the upper and lower clamping parts are equipped with scales.

[0011] It also includes a column, with a guide rail installed at the top of the column. The electroplating fixture includes a conveying part, which is vertically located above the upper plate and is slidably connected to the guide rail.

[0012] A lifting mechanism is installed at the lower end of the column, which is used to control the vertical movement of the lower plate.

[0013] Both the lower support and the lower clamping part are located on the lifting part.

[0014] A scale is vertically installed on the column, and a pointer is installed on the lifting part, with the pointer matching the scale.

[0015] The electroplating fixture includes a sliding rod, the lower end of which is fixedly connected to the lower plate, and the upper end of which is adjustablely snapped into the upper plate.

[0016] The lower support section has lifting slots, and the number of lifting slots is the same as that of the sliding rods, and they slide in a corresponding manner.

[0017] The lifting unit is equipped with a limit groove, which is used to limit the lower plate.

[0018] The lifting unit can drive the lower support unit, lower opening clamp unit, lower plate, lower clamping group and sliding rod to move vertically up and down synchronously.

[0019] This utility model has the following beneficial effects:

[0020] This invention achieves a step-by-step opening action by setting the push plate with a height difference, so that the middle of the push plate surface separates from the clamps before the sides. That is, the pushing mechanism first moves the middle area of ​​the push plate surface to prevent it from contacting the clamps of the upper and lower clamping groups, thereby closing the middle clamp of the upper and lower clamping groups of the electroplating fixture. After the middle clamping area provides initial support for the electroplating material, the push plate surface then moves the sides to prevent it from contacting the clamps of the upper and lower clamping groups, thereby closing the remaining clamps of the upper and lower clamping groups of the electroplating fixture. This effectively avoids the wrinkling problem caused by the material sagging due to its own weight in the traditional synchronous opening method, and ensures the flatness of the material during the loading and unloading process.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-7 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown:

[0032] This embodiment provides an anti-wrinkle loading and unloading clamping device for an electroplating fixture 13. The electroplating fixture 13 includes an upper plate 131, an upper clamping assembly 132, a lower plate 133, and a lower clamping assembly 134. The upper clamping assembly 132 and the lower clamping assembly 134 are used to clamp the upper and lower ends of the electroplating sheet, including:

[0033] Upper support 1 is used to support the upper plate 131;

[0034] The upper clamping part 2 is provided corresponding to the upper support part 1, and the upper clamping part 2 is used to control the upper clamping assembly 132;

[0035] The lower support part 3 is used to support the lower plate 133;

[0036] The lower clamping part 4 is provided corresponding to the lower support part 3, and the lower clamping part 4 is used to control the lower clamping assembly 134;

[0037] The upper clamping part 2 and the lower clamping part 4 have the same structure, both including a pushing mechanism 14 and a push plate 5. The upper clamping group 132 and the lower clamping group 134 are composed of multiple clamps. The pushing mechanism 14 is used to drive the push plate 5 to contact the clamp to control the clamp to open and close. The horizontal height of the middle and the sides of the contact surface between the push plate 5 and the clamp is not the same, forming at least two layers of height difference, so that the middle of the surface of the push plate 5 will leave the clamp first compared with the sides.

[0038] During loading, the pushing mechanism 14 is first activated, driving the push plate 5 to gradually approach the clamps of the upper clamping group 132 and the lower clamping group 134, and finally pressing the clamps open. Because the surface of the push plate 5 is concave, its surface height is inconsistent, resulting in a smaller opening angle for the clamps corresponding to the middle area of ​​the push plate 5 surface and a larger opening angle for the clamps corresponding to the two sides of the surface. At this time, both ends of the electroplated sheet are placed in the upper clamping group 132 and the lower clamping group 134. After the electroplated sheet is placed, the pushing mechanism 14 is activated for the first retraction. At this time, the middle area of ​​the push plate 5 surface retracts until it is no longer in contact with the clamps. Meanwhile, the two sides of the push plate 5 are still in contact with the clamps, so that the middle clamps of the upper clamp group 132 and the lower clamp group 134 first clamp the middle of the electroplated sheet. By fixing the middle, the downward trend of the electroplated sheet is restricted. Then, the push mechanism 14 is activated to retract for the second time, which drives the push plate 5 to continue to retract. This way, the two sides of the push plate 5 are no longer in contact with the clamps of the upper clamp group 132 and the lower clamp group 134, so that the remaining clamps of the upper clamp group 132 and the lower clamp group 134 clamp the two ends of the electroplated sheet, completing the clamping. Through this step-by-step clamping, wrinkles caused by the weight of the electroplated sheet can be avoided.

[0039] Both the upper clamping part 2 and the lower clamping part 4 are equipped with scales so that operators can clearly know the distance that the pushing mechanism drives the push plate to move.

[0040] It should be noted that the above description only describes the push plate 5 as having a two-layer height difference. However, in actual use, the push plate 5 can be set to a three-layer or multi-layer height difference according to the specific implementation method. The push mechanism 14 is used to perform multiple retraction movements to control the clamp to close and hold the electroplated sheet.

[0041] like Figure 2 , Figure 6 As shown, it also includes a column 6, with a guide rail 7 installed at the upper end of the column 6. The electroplating fixture 13 includes a conveying part 135, which is vertically located above the upper plate 131. The conveying part 135 is slidably connected to the guide rail 7. A lifting part 8 is installed at the lower end of the column 6. The lifting part 8 moves up and down along the column 6 and can synchronously control the lower plate 133 to move vertically.

[0042] like Figure 1 , Figure 6As shown, the lower support part 3 and the lower clamping part 4 are both set on the lifting part 8. The lifting part 8 can drive the lower support part 3, the lower clamping part 4, the lower plate 133, the lower clamping group 134 and the sliding rod 136 to move vertically up and down synchronously. The upper support part 1 and the lower support part 3 are always vertically aligned, so that the length of the electroplating hanger 13 can be adjusted synchronously, and the lower clamping part 4 can be accurately aligned with the lower clamping group 134 of the electroplating hanger 13 to open the clamp, so as to be able to adapt to the electroplating hanger 13 to clamp electroplating plates of different sizes.

[0043] like Figure 1 , Figure 4 , Figure 6 As shown, a scale 9 is vertically installed on the column 6, and a pointer 10 is installed on the lifting part 8. The pointer 10 matches the scale 9 and is used to accurately determine the lifting height of the lower plate 133 and the length of the electroplating fixture 13.

[0044] like Figure 1 , Figure 3 , Figure 5 , Figure 6 As shown, the lower support part 3 has a lifting slot 11. The electroplating hanger 13 includes a sliding rod 136. The lower end of the sliding rod 136 is fixedly connected to the lower plate 133, and the upper end of the sliding rod 136 is adjustablely engaged with the upper plate 131. The lifting slot 11 and the sliding rod 136 are the same in number and correspond to each other in sliding cooperation. The lifting part 8 is provided with a limiting groove 12. The limiting groove 12 is used to limit the lower plate 133, thereby limiting the electroplating hanger 13 and ensuring that the electroplating hanger 13 and the lifting part 8 can maintain vertical correspondence when they move up and down, preventing the electroplating hanger 13 from tilting.

[0045] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
