Description

Technical Field

[0001] This utility model belongs to the field of bracket processing technology, and in particular relates to a clamping device for stamping LED lamp brackets. Background Technology

[0002] LED lamp brackets are metal structural components that support and fix LED beads. They are formed into specific shapes through a stamping process to provide a stable mounting base for the LED beads and ensure that they maintain their position in vibration or impact environments. LED brackets are usually made using a stamping process, and during the stamping process, clamping devices are usually used to fix the position of the LED bracket to prevent the LED bracket from shifting during the stamping process.

[0003] Chinese patent publication number 202221767174.7 discloses an OG bracket stamping and fixing device. It includes a worktable, a movable plate, and a pushing mechanism. The pushing mechanism includes a movable groove and a limiting slide groove. The movable groove is located inside the worktable, and the limiting slide groove is located on the top surface of the worktable. The movable groove and the limiting slide groove are connected. A braking component is provided inside the movable groove, and a screw is connected to the output end of the braking component. A screw bearing is connected to the inside of the movable groove. A limiting slider is provided on the bottom surface of the movable plate, and a threaded hole is provided inside the limiting slider. The limiting slider is movably connected to the limiting slide groove, and the screw is threadedly connected to the inside of the threaded hole. Through the pushing mechanism, when the movable plate needs to be moved, there is no need for manual pushing; simply turning on the motor allows the motor to move the movable plate, making the movement of the movable plate easier. Furthermore, the fully mechanized components avoid errors caused by manual movement.

[0004] According to the aforementioned patent, there exists a clamping device for stamping LED lamp holders. However, the existing technology has the following problems when in use: the current clamping device is usually a fixed rigid structure that directly clamps the lamp holder by relying on the mechanical force of the rigid components. It lacks an elastic buffer structure. When the clamping force is too large, the rigid force acts directly on the surface of the LED lamp holder, which can easily lead to edge indentations, surface scratches, or even cracking of thin lamp holders. On the other hand, the impact force during stamping is directly transmitted to the lamp holder through the rigid clamping components without any buffering space, which further aggravates the risk of lamp holder deformation and reduces the product qualification rate. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a clamping device for stamping LED lamp brackets, comprising: The operating table and support frame are provided. The support frame is fixedly installed on the top of the operating table. The top of the support frame is provided with a negative pressure chamber and a mounting groove. A negative pressure adsorption plate for fixing the LED lamp bracket is fixedly connected to the top of the negative pressure chamber. A corrugated gasket is provided in the inner cavity of the mounting groove. An elastic gasket is provided on the top of the corrugated gasket. An inclined part is provided on the inner side of the elastic gasket. Negative pressure is applied to the LED lamp holder by the negative pressure adsorption plate, which drives the LED lamp holder to adhere to one side of the negative pressure adsorption plate. At this time, the elastic gasket is compressed by the driving force and undergoes elastic deformation, using its own deformation characteristics to fill the gap between the LED lamp holder and the negative pressure adsorption plate.

[0006] Furthermore, the elastic pad and the inclined portion are integrally molded from silicone material.

[0007] Furthermore, a negative pressure pump is fixedly connected to the inner cavity of the support frame, and an adsorption tube is provided at the air inlet end of the negative pressure pump. The air inlet end of the adsorption tube passes through the inner cavity of the support frame and communicates with the inner cavity of the negative pressure chamber.

[0008] Furthermore, the side wall of the adsorption tube is connected to a connecting tube, the end of the connecting tube penetrates the side wall of the negative pressure chamber and is fixedly equipped with a pressure relief valve, the side wall of the connecting tube is connected to a suction tube, and the end of the suction tube is connected to the inner cavity of the mounting groove.

[0009] Furthermore, a mounting frame is fixedly connected to the bottom of the corrugated gasket, and the bottom of the mounting frame is provided with an adsorption hole adapted to the suction pipe.

[0010] Furthermore, positioning plates are fixedly connected to both ends of the top of the support frame.

[0011] Furthermore, a stamping machine for forming is fixedly connected to the top of the operating table.

[0012] Furthermore, the top of the negative pressure adsorption plate is provided with an opening, which is arranged in rows and columns along the top of the negative pressure adsorption plate.

[0013] Furthermore, a lower mold fixing groove is provided at the middle of the top of the support frame.

[0014] Compared with the prior art, the clamping device for stamping LED lamp brackets described in this utility model has the following advantages: 1. By using a combination of elastic and corrugated gaskets, traditional rigid clamping components are replaced. Utilizing the elasticity of silicone and the compressibility of the corrugated structure, the clamping force is transmitted to the LED lamp holder surface through flexible contact. When the clamping force is applied, the elastic and corrugated gaskets adapt to deformation, preventing edge indentations and surface scratches caused by direct rigid force compression. It also provides suction clamping for thin lamp holders, reducing the risk of cracking due to clamping force overload. Simultaneously, the impact force generated during stamping is buffered and dissipated by the deformation of the corrugated gaskets, reducing the risk of deformation caused by direct impact force transmission to the lamp holder. 2. By incorporating a suction pipe and suction holes, when the negative pressure pump clamps the LED lamp holder through the suction pipe and negative pressure suction plate, the suction pipe, in conjunction with the suction holes, secures the mounting frame. After the pressure relief valve releases pressure, the corrugated and elastic gaskets can be disassembled for convenient use. Attached Figure Description

[0021] like Figures 1-4 As shown, a clamping device for stamping LED lamp brackets includes: The operating table 100 and the support frame 200 are fixedly installed on the top of the operating table 100. The top of the support frame 200 is provided with a negative pressure chamber 220 and a mounting groove 222. The top of the negative pressure chamber 220 is fixedly connected to a negative pressure adsorption plate 221 for fixing the LED lamp bracket. The inner cavity of the mounting groove 222 is provided with a corrugated gasket 240. The top of the corrugated gasket 240 is provided with an elastic gasket 250. The inner side of the elastic gasket 250 is provided with an inclined part 251. Negative pressure is applied to the LED lamp holder by the negative pressure adsorption plate 221, which drives the LED lamp holder to adhere to one side of the negative pressure adsorption plate 221. At this time, the elastic pad 250 is compressed by the driving force and the corrugated pad 240 undergoes elastic deformation, using its own deformation characteristics to fill the gap between the LED lamp holder and the negative pressure adsorption plate 221.

[0022] As a preferred example of this utility model, the support frame 200 is fixed to the top of the operating table 100 to form an integral frame; the negative pressure cavity 220 at the top of the support frame 200 cooperates with the negative pressure adsorption plate 221, and drives the LED lamp bracket to fit against the negative pressure adsorption plate 221 through the negative pressure action to achieve fixation. The corrugated gasket 240 in the mounting groove 222 provides elastic support for the elastic gasket 250. When the LED lamp bracket is fitted under negative pressure, the elastic gasket 250 is compressed and compresses the corrugated gasket 240. Its own elastic deformation can fill the tiny gap between the lamp bracket and the negative pressure adsorption plate 221. Even if the surface of the LED lamp bracket is uneven or has thickness deviation, it can ensure tight fit, improve clamping stability, and reduce damage to the lamp bracket through elastic buffering.

[0023] In the example of this application, the elastic pad 250 and the inclined portion 251 are integrally molded from silicone material.

[0024] As a preferred example of this utility model, the elastic gasket 250 and the inclined portion 251 are integrally molded from silicone material. Silicone itself has good elasticity and sealing properties, which can ensure that the two always fit tightly when subjected to pressure deformation.

[0025] In the example of this application, a negative pressure pump 210 is fixedly connected to the inner cavity of the support frame 200. An adsorption pipe 211 is provided at the air inlet end of the negative pressure pump 210. The air inlet end of the adsorption pipe 211 passes through the inner cavity of the support frame 200 and communicates with the inner cavity of the negative pressure chamber 220.

[0026] As a preferred example of this utility model, the negative pressure pump 210 in the inner cavity of the support frame 200 provides an active power source for negative pressure. The adsorption pipe 211 at its air inlet end directly penetrates the support frame 200 and connects to the negative pressure chamber 220. Air is drawn from inside the negative pressure chamber 220 through the adsorption pipe 211, and the LED lamp bracket is clamped by the negative pressure adsorption plate 221.

[0027] In the example of this application, the side wall of the adsorption tube 211 is connected to the connecting tube 212, the end of the connecting tube 212 penetrates the side wall of the negative pressure chamber 220 and is fixedly provided with a pressure relief valve 214, the side wall of the connecting tube 212 is connected to the suction tube 213, and the end of the suction tube 213 is connected to the inner cavity of the mounting groove 222.

[0028] As a preferred example of this utility model, one end of the connecting pipe 212 on the side wall of the adsorption tube 211 is connected to the pressure relief valve 214. After the stamping is completed, opening the pressure relief valve 214 can release the negative pressure in the negative pressure chamber 220. The other end is connected to the mounting groove 222 through the suction pipe 213, so that the negative pressure acts synchronously in the mounting groove 222, pushing the corrugated gasket 240 and the elastic gasket 250 to fit against the bottom of the mounting groove 222, thereby fixing the corrugated gasket 240 and the elastic gasket 250.

[0029] In the example of this application, the bottom of the corrugated gasket 240 is fixedly connected to the mounting frame 230, and the bottom of the mounting frame 230 is provided with an adsorption hole 231 that is adapted to the suction pipe 213.

[0030] As a preferred example of this utility model, the mounting frame 230 at the bottom of the corrugated gasket 240 provides a stable mounting reference; the suction hole 231 at the bottom of the mounting frame 230 is adapted to the suction pipe 213, so that negative pressure can be applied to the bottom of the mounting frame 230 to fix the mounting frame 230.

[0031] In the example of this application, positioning plates 260 are fixedly connected to both ends of the top of the support frame 200.

[0032] As a preferred example of this utility model, the positioning plates 260 at both ends of the top of the support frame 200 serve as guides when the lamp holder is placed, guiding the operator to place the LED lamp holder in the designated area of ​​the negative pressure adsorption plate 221, reducing placement deviation; at the same time, the positioning plates 260 can restrict the horizontal movement of the lamp holder, forming a bidirectional constraint with the vertical fixation of the negative pressure adsorption plate 221.

[0033] In the example of this application, a stamping machine 110 for forming is fixedly connected to the top of the operating table 100.

[0034] As a preferred example of this utility model, a stamping machine 110 is fixed to the top of the operating table 100. The stamping machine 110 is used for stamping the LED lamp bracket. Specifically, the stamping machine 110 is existing technology and can be driven by a telescopic cylinder, allowing for manual stamping. Further details will not be provided. In the example of this application, the top of the negative pressure adsorption plate 221 is provided with an opening 223, and the opening 223 is distributed in rows and columns along the top of the negative pressure adsorption plate 221.

[0035] As a preferred example of this utility model, the openings 223 arranged in rows and columns on the top of the negative pressure adsorption plate 221 make the negative pressure of the negative pressure chamber 220 distributed on the surface of the plate, avoiding local lifting or loose adhesion due to insufficient adsorption force.

[0036] In the example of this application, a lower mold fixing groove 261 is provided at the middle of the top of the support frame 200, and two sets of openings 223 are provided, respectively located on both sides of the lower mold fixing groove 261.

[0037] As a preferred example of this utility model, the lower die fixing groove 261 at the top center of the support frame 200 provides a dedicated mounting position for the stamping lower die, ensuring the lower die is fixed and improving the equipment's versatility and production flexibility.

[0038] In practical use, the top of the operating table 100 is also fixedly connected to a stamping machine 110 for stamping the LED lamp bracket. The support frame 200 has a lower mold fixing groove 261 at the middle of its top, which provides a dedicated mounting position for the stamping lower mold. The positioning plates 260 fixedly connected to both ends of the top of the support frame 200 can play a guiding role when the LED lamp bracket is placed. The negative pressure adsorption plate 221 has openings 223 arranged in rows and columns along its top, which can make the negative pressure of the negative pressure chamber 220 distributed on the surface of the plate. Once the LED light bracket is in place, the negative pressure pump 210, fixedly connected to the inner cavity of the support frame 200, starts as an active negative pressure power source. Its air inlet end has an adsorption pipe 211 that penetrates the inner cavity of the support frame 200 and communicates with the inner cavity of the negative pressure chamber 220. Air is drawn from the negative pressure chamber 220 through the adsorption pipe 211, causing the negative pressure adsorption plate 221 to apply negative pressure to the LED light bracket, driving the LED light bracket to adhere to one side of the negative pressure adsorption plate 221 for fixation. The end of the suction pipe 213 connected to its side wall is connected to the top of the support frame 200. The inner cavity of the mounting groove 222 is connected, and the suction pipe 213 is also adapted to the suction hole 231 opened at the bottom of the mounting frame 230, which is fixedly connected to the bottom of the corrugated gasket 240. This allows the negative pressure to act synchronously within the mounting groove 222 and on the bottom of the mounting frame 230, thus fixing the mounting frame 230. The mounting frame 230 serves as the mounting reference for the corrugated gasket 240. The negative pressure pushes the corrugated gasket 240 and the elastic gasket 250 to fit against the bottom of the mounting groove 222, thereby fixing the corrugated gasket 240 and the elastic gasket 250. At this time, under the negative pressure... The driving force of the LED lamp holder compresses the elastic pad 250, which in turn compresses the corrugated pad 240 and undergoes elastic deformation. Since the elastic pad 250 and the inner inclined portion 251 are integrally molded from silicone, their deformation characteristics fill the tiny gap between the LED lamp holder and the negative pressure adsorption plate 221. After the LED lamp holder is stably clamped, the stamping machine 110 can perform stamping and forming. After stamping, opening the pressure relief valve 214 releases the negative pressure in the negative pressure chamber 220, thus completing the operation. The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many other forms without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
