An automatic loading and unloading opening and closing device

Abstract

This utility model discloses an automatic loading and unloading clamping device, relating to the field of electroplating technology. The utility model includes an upper support part, an upper clamping part, a lower support part, and a lower clamping part; the upper and lower clamping parts have identical structures, each including at least three horizontally arranged clamping sections. By setting three independent clamping sections in both the upper and lower clamping parts, this utility model enables a step-by-step clamping action during loading, starting with the middle section and then moving to the sides. Specifically, the drive mechanism first triggers the middle clamping section to close 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, the side clamping sections are then triggered to close 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, ensuring the flatness of the material during loading and unloading.

Description

Technical Field

[0001] This utility model belongs to the field of electroplating technology, and specifically relates to an automatic 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 automatic 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, each including at least three horizontally arranged clamping parts. The upper and lower clamping groups are composed of multiple clamps. The clamping parts are used to control the opening and closing movements of the upper and lower clamping groups. The clamping part located in the middle controls the corresponding clamps in the upper and lower clamping groups to perform clamping operations first, compared to the clamping parts on both sides.

[0010] The column has a guide rail installed at its upper end. The electroplating fixture includes a conveyor section, which is vertically located above the upper plate and is slidably connected to the guide rail.

[0011] A lifting mechanism is installed at the lower end of the column, which is used to control the vertical movement of the lower plate.

[0012] Both the lower support and the lower clamping part are located on the lifting part.

[0013] A scale is vertically installed on the column, and a pointer is installed on the lifting part, with the pointer matching the scale.

[0014] 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.

[0015] 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.

[0016] The lifting unit is equipped with a limit groove, which is used to limit the lower plate.

[0017] The upper support and the lower support are always vertically aligned.

[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 features three independent clamping sections in both the upper and lower clamping parts, enabling a step-by-step clamping action during loading: first the middle, then the sides. The drive mechanism first triggers the middle clamping section to close the middle clamp of the upper and lower clamping groups of the electroplating fixture. After the middle clamping area provides initial support for the electroplated material, the side clamping sections are then triggered to close 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 under its own weight in the traditional synchronous clamping method, ensuring the flatness of the material during loading and unloading.

[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

[0029] 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 appendices of the embodiments of this utility model. Figure 1-6 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.

[0030] Please see Figure 1 , Figure 2 , Figure 6 As shown:

[0031] This embodiment provides an automatic 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:

[0032] Upper support 1 is used to support the upper plate 131;

[0033] 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;

[0034] The lower support part 3 is used to support the lower plate 133;

[0035] 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;

[0036] The upper clamping part 2 and the lower clamping part 4 have the same structure, both including at least three clamping parts 5 arranged horizontally. The upper clamping group 132 and the lower clamping group 134 are composed of multiple clamps arranged horizontally. The clamping parts 5 are used to control the opening and closing movements of the upper clamping group 132 and the lower clamping group 134. The clamping part 5 located in the middle controls the corresponding clamps in the upper clamping group 132 and the lower clamping group 134 to perform clamping operations first compared to the clamping parts 5 on both sides.

[0037] Each clamping part 5 is equipped with a driving mechanism. In actual use, when loading materials, the driving mechanism first drives the clamping parts 5 of the upper clamping part 2 and the lower clamping part 4 to press the upper clamping group 132 and the lower clamping group 134 of the electroplating hanger 13, so that the clamps are all in the open state. The opening width can be adjusted according to the thickness of the electroplating material. Then, the two ends of the electroplating material are placed in the upper clamping group 132 and the lower clamping group 134. After the electroplating material is placed, the middle clamping part 5 is reset first. The upper clamping group 132 and the lower clamping group 134 of the electroplating hanger 13 clamp the middle of the electroplating material first, and the downward trend of the electroplating material is restricted by the middle fixation. Then, the left and right clamping parts 5 are reset, so that the remaining clamps of the upper clamping group 132 and the lower clamping group 134 on both sides clamp the two ends of the electroplating material, and the clamping is completed, thereby avoiding wrinkles caused by the weight of the electroplating material itself.

[0038] 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.

[0039] like Figure 1 , Figure 6 As 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.

[0040] 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.

[0041] like Figure 1 , Figure 3 , Figure 5 , Figure 6As 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.

[0042] 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.

[0043] 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.
