Description

Technical Field

[0001] This utility model relates to the field of compression molding equipment technology, and in particular to an electromagnetic sealing gasket compression fixture. Background Technology

[0002] Electromagnetic sealing gaskets are a key component widely used in electronic equipment. Their main function is to provide environmental sealing while achieving electromagnetic shielding, thus ensuring the normal and stable operation of the equipment.

[0003] In the production process of electromagnetic sealing gaskets, a pressing machine is usually used in conjunction with a specific mold to press the raw materials into shape. In the existing production method, after the pressing step is completed, the formed gasket is still left in the mold cavity of the lower mold. In order to carry out the next round of production, the formed gasket must be removed from the mold cavity. In the conventional production process, this removal action often relies on manual operation, that is, the operator manually takes the gasket out of the mold. This reliance on manual removal directly leads to a low degree of automation in the entire production process, and production efficiency is thus significantly restricted.

[0004] Because manual handling of parts and materials is required, the pressing equipment has to stop and cannot operate continuously and efficiently. This constitutes a significant bottleneck in the production cycle. At the same time, relying entirely on manual operation not only increases the company's labor costs, but also poses risks of inconvenience and damage to products or molds when handling some small or delicate pads, thus affecting the product yield.

[0005] Therefore, this utility model proposes an electromagnetic sealing gasket pressing fixture to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of existing electromagnetic sealing gasket pressing fixtures, such as the need for manual removal after pressing and forming, which leads to inconvenience in operation and low production efficiency, this utility model aims to provide an electromagnetic sealing gasket pressing fixture with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an electromagnetic sealing gasket pressing fixture, including: a pressing machine, an upper mold, a lower mold, an ejection mechanism, a pushing mechanism, a conveying mechanism, and a controller.

[0008] The ejection mechanism, the pushing mechanism, and the conveying mechanism are combined in a specific spatial relationship. The ejection mechanism is located below the lower mold, the pushing mechanism is located on one side of the lower mold and its movement path crosses the top of the lower mold. The bearing surface of the conveying mechanism is lower than the top surface of the lower mold and is adjacent to the movement endpoint of the pushing mechanism. The controller is used to coordinate and control the automated actions of the above mechanisms.

[0009] Preferably, the ejection mechanism includes a hollow block, a spring, an ejection column, and a drive assembly. The ejection column is slidably disposed inside the hollow block, the spring is sleeved on the outside of the ejection column, and the drive assembly is used to drive the ejection column to move upward to eject the pad.

[0010] Preferably, the drive assembly includes a motor, a cam, and a connecting rod. The output end of the motor is connected to the connecting rod. A plurality of cams are fixed on the outer side of the connecting rod. When the cams rotate, they slide into contact with the protruding wheel at the bottom of the ejector column to push the ejector column.

[0011] Preferably, one end of the spring abuts against the inner wall of the hollow block, and the other end abuts against the flange of the ejector post, so that the spring is compressed when the ejector post is pushed, and provides a restoring force to the ejector post after the ejection action is completed.

[0012] Preferably, the pushing mechanism includes an electric push rod and a push plate, wherein the push plate is connected to the extended end of the electric push rod.

[0013] Preferably, the conveying mechanism includes a U-shaped long plate, a second rotating wheel, a conveyor belt, a first rotating wheel, and a power assembly. The first rotating wheel and the second rotating wheel are rotatably mounted at both ends of the U-shaped long plate, and the conveyor belt surrounds the outside of the first rotating wheel and the second rotating wheel.

[0014] Preferably, the power assembly includes a second motor and a connecting short column. The output end of the second motor is connected to the connecting short column, and the outer side of the connecting short column is connected to the first impeller to drive the conveyor belt.

[0015] Preferably, the lower mold has an arc-shaped feeding plate on its front side, which is located below the movement path of the pushing mechanism and above the conveyor belt of the conveying mechanism.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem in the prior art that after the electromagnetic sealing gasket is pressed and formed, it is necessary to manually remove it from the mold and transfer it, which leads to inconvenience and low production efficiency. It achieves the function of automatically ejecting, pushing and conveying the formed gasket, which greatly improves production efficiency and reduces the intensity of manual labor.

[0018] 2. This utility model solves the problem of product damage or unstable picking speed caused by uneven force during manual picking by setting up an ejection mechanism driven by a motor and actuated by the cam to push the ejection column, and using a spring to reset the ejection column. It achieves the technical effect of stable and reliable ejection action, simple structure and high durability, and ensures that the liner can be smoothly removed from the mold.

[0019] 3. This utility model, by setting a pushing mechanism to push the ejected pad onto the conveying mechanism below, and using the conveying mechanism to transport the pad away, solves the problem that finished products tend to accumulate next to the equipment after unloading, requiring secondary manual collection. It achieves the effect of automated unloading and conveying integration, avoids material accumulation, and makes the entire production process smoother and more continuous.

The arc-shaped material feeding plate is located below the movement path of the pushing mechanism 5 and above the conveyor belt 303 of the conveying mechanism 3.

[0035] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0036] As a preferred embodiment, please refer to Figure 2 and Figure 3 To achieve reliable ejection and automatic reset of the liner, the ejection mechanism 2 includes a hollow block 201, a spring 202, an ejection post 203, and a drive assembly 204. The ejection post 203 is slidably disposed inside the hollow block 201. The spring 202 is sleeved on the outside of the ejection post 203, with one end abutting against the inner wall of the hollow block 201 and the other end abutting against the flange of the ejection post 203. Furthermore, to achieve precise ejection drive, the drive assembly 204 includes a motor 2041, a cam 2042, and a connecting rod 2043. The output end of the motor 2041 is fixedly connected to the connecting rod 2043. Multiple cams 2042 are fixed on the outside of the connecting rod 2043. When each cam 2042 rotates, it slides in contact with a protruding wheel at the bottom of an ejection post 203.

[0037] In a preferred embodiment, in order to provide a stable linear driving force, the driving mechanism 5 includes an electric push rod 501 and a push plate 502, with the push plate 502 fixedly connected to the extended end of the electric push rod 501.

[0038] As a preferred embodiment, please refer to Figure 1 and Figure 4 To achieve automated conveying of the padding, the conveying mechanism 3 includes a U-shaped long plate 301, a second rotating wheel 302, a conveyor belt 303, a first rotating wheel 304, and a power assembly 305. The first rotating wheel 304 and the second rotating wheel 302 are rotatably mounted at both ends of the U-shaped long plate 301. The conveyor belt 303 is wrapped around the outside of the first rotating wheel 304 and the second rotating wheel 302. Furthermore, to drive the conveyor belt 303, the power assembly 305 includes a second motor 3051 and a connecting short column 3052. The output end of the second motor 3051 is connected to the connecting short column 3052, and the outside of the connecting short column 3052 is fixedly connected to the first rotating wheel 304.

[0039] As a preferred embodiment, in order to ensure that the liner can be smoothly transferred from the lower mold 4 to the conveying mechanism 3, an arc-shaped feeding plate is provided on the front side of the lower mold 4. The arc-shaped feeding plate is located below the movement path of the pushing mechanism 5 and above the conveyor belt 303 of the conveying mechanism 3, forming a smooth transition.

[0040] Working principle: When the equipment is working, the press machine 1 is started, which drives the upper mold 6 to press down and press the raw material placed on the lower mold 4 into an electromagnetic sealing gasket. After pressing is completed, the motor 2041 in the drive assembly 204 is started. The motor 2041 drives the connecting rod 2043 at the output end to rotate. During the rotation of the connecting rod 2043, it will drive multiple cams 2042 fixed on the outside to rotate synchronously. When the cams 2042 rotate, they will slide with the protruding wheels at the bottom of the multiple ejection columns 203 that are slidably connected in the hollow block 201 in the ejection mechanism 2. This pushes the ejection columns 203 to push the electromagnetic sealing gasket pressed in the lower mold 4 up and down to achieve ejection and unloading. During the sliding process, the ejection columns 203 will simultaneously compress the spring 202 to contract. After ejection is completed, the spring 202 will rebound to complete the reset, thus solving the problem of inconvenience caused by manual unloading.

[0041] After the electromagnetic sealing gasket is ejected, the controller 7 controls the electric push rod 501 in the pushing mechanism 5. The electric push rod 501 extends to push the push plate 502 to push the ejected sealing gasket down. The sealing gasket will slide down the arc-shaped unloading plate on the front side of the lower mold 4 and fall onto the conveyor belt 303 in the conveying mechanism 3. Then, the motor 3051 in the power assembly 305 on the front side of the U-shaped long plate 301 is started to drive the connecting short column 3052 at the output end to rotate. Since the outer side of the connecting short column 3052 is connected to the first rotating wheel 304, and the conveyor belt 303 is on the outer side of the first rotating wheel 304, when the first rotating wheel 304 rotates, it will drive the second rotating wheel 302 to rotate synchronously through the conveyor belt 303, so as to automatically convey and unload the reinforced electromagnetic sealing gasket and enhance the production efficiency of the equipment.
