Description

Technical Field

[0001] This utility model relates to the field of rubber film coating technology, and in particular to a coating device for the production of automotive brake rubber films. Background Technology

[0002] The adhesive coating device for automotive brake rubber diaphragm production is a specialized piece of equipment used in the adhesive coating process of automotive brake rubber diaphragms. Its main function is to uniformly and precisely coat the adhesive onto specific areas of the rubber diaphragm surface to meet its sealing, bonding, and other performance requirements.

[0003] However, in the existing technology, the device uses simple clamps or suction cups to fix the rubber diaphragm. For diaphragms of different shapes, sizes and materials, this fixing method may not provide sufficient stability. During the coating process, the diaphragm is prone to displacement or shaking due to external forces, which affects the coating accuracy. Therefore, a coating device for the production of automotive brake rubber diaphragms is needed. Utility Model Content

[0004] The purpose of this invention is to provide a coating device for the production of automotive brake rubber diaphragms, which solves the problems in the prior art where the clamps cannot fix diaphragms of different specifications and have weak clamping stability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a coating device for producing automotive brake rubber diaphragms, comprising a workbench, a support cover disposed above the workbench for support and protection, a nozzle for spraying adhesive material penetrating inside the support cover, the nozzle being connected to an adhesive storage tank for storing adhesive material via a pressurizing pump, and a clamping assembly for holding the diaphragm disposed above the workbench and below the nozzle.

[0006] Preferably, the workbench has a sliding groove inside.

[0007] Preferably, the sliding groove is provided in six sets, and the six sets of sliding grooves are distributed in a ring about the central axis of the worktable.

[0008] Preferably, the clamping assembly includes a rotating disk, an arc-shaped groove, a moving rod, a limiting block, and a clamp. The rotating disk has an arc-shaped groove inside, the moving rod is fitted inside the arc-shaped groove, the outer wall of the moving rod is connected to the limiting block, and the top end of the moving rod is connected to the clamp.

[0009] Preferably, the limiting block is adapted to the size and dimensions of the sliding groove, and the outer wall of the limiting block is fitted inside the sliding groove.

[0010] Preferably, the angle between the extension axis of the arc-shaped groove and the central diameter of the rotating disk is 45°.

[0011] Preferably, the device further includes a rotary motor and a fixing component, wherein the output end of the rotary motor is connected to the rotating disk, and the outer wall of the rotary motor is connected to the fixing component.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The rotating disk is driven by a rotary motor to rotate, causing the moving rod to move inside the arc groove. At the same time, the limiting block slides inside to restrict the movement of the fixture, allowing the fixture to move closer to or away from the center of the rotating disk, locking the film placed above the worktable. Then, the adhesive is sprayed onto the film through the nozzle to complete the uniform spraying. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model relates to a coating device for producing automotive brake rubber diaphragms, such as... Figure 1-4As shown, the device includes a workbench 1 and a support cover 2 located above the workbench 1 for support and protection. A nozzle 3 runs through the inside of the support cover 2, spraying adhesive onto the diaphragm. The nozzle 3 is connected to a pressure pump 4 via a pipe, which pressurizes and extracts the adhesive. The pressure pump 4 is also connected to a storage tank 5 via a pipe, allowing adhesive to be injected into the storage tank 5 for convenient use. A clamping assembly 6 is provided above the workbench 1 to reinforce diaphragms of different sizes and prevent uneven movement during adhesive spraying. A foot bracket 7 is also provided at the bottom of the workbench 1 to support the entire device. The workbench 1 has six sets of sliding grooves 8 arranged in a ring around the central axis of the workbench 1.

[0021] Among them, such as Figure 3 As shown, the clamping assembly 6 includes a rotating disk 601, a rotary motor 602, a fixing member 603, an arc-shaped groove 604, a moving rod 605, a limiting block 606, and a clamp 607. The bottom of the rotating disk 601 is fixedly connected to the output end of the rotary motor 602. The outer wall of the rotary motor 602 is fixedly connected to one end of the fixing member 603, and the other end of the fixing member 603 is fixed to the bottom of the worktable 1. The rotary motor 602 drives the rotating disk 601 to rotate. An arc-shaped groove 604 is provided inside the rotating disk 601, and a moving rod 605 is provided inside the arc-shaped groove 604. The rotation of the rotating disk 601 causes the moving rod 605 to move along the extension direction of the arc-shaped groove 604. The size and dimensions of the arc-shaped groove 604 are adapted to the moving rod 605. The outer wall of the moving rod 605... A fixed connection limit block 606 is provided, and a clamp 607 is provided at the top of the moving rod 605. The limit block 606 serves to limit the moving direction of the clamp 607. The extension axis of the arc groove 604 forms an angle of 45° with the central diameter of the rotating disk 601. The rotating disk 601 is located below the sliding groove 8. The bottom of the sliding groove 8 has a groove that matches the rotating disk 601. The size and dimensions of the sliding groove 8 are adapted to the limit block 606, so that the rotating disk 601 drives the moving rod 605 to move the clamp 607 closer to or away from the center of the rotating disk 601 under the cooperation of the limit block 606 and the sliding groove 8, thereby achieving the function of clamping and fixing. The clamp 607 will contact the film but will not be rigidly locked. The position of the film is locked by slight contact to prevent the film from moving during spraying.

[0022] In practical use: the rotary motor 602 drives the rotating disk 601 to rotate, causing the moving rod 605 to move inside the arc groove 604. At the same time, the limiting block 606 will slide inside the groove 8, restricting the movement position of the clamp 607, so that the clamp 607 can move closer to or away from the center of the rotating disk 601, locking the film placed above the worktable 1. Then, the adhesive is sprayed onto the film through the nozzle 3 to complete the uniform spraying.
