[0025] In order to describe the present invention in detail, first, the laminating device for conductive foam of the present invention is specifically described below.

[0026] like Figures 1 to 3 As shown, the present application provides a bonding device for conductive foam, including a frame 1, a rotating mechanism 2 and a movable frame 3, wherein the movable frame 3 is mounted on the frame 1, and the rotating mechanism 2 is mounted on the movable frame 3. The frame 1 is provided with a workbench 101 for bonding and a conveyor belt 102 for conveying products. The conveyor belt 102 drives the electronic products to move, so that during the entire process, the operator does not touch the unassembled electronic products and does not generate static electricity, thereby affecting the product quality. The frame 1 is also provided with an indicator light 103 and a display screen 104. The indicator light 103 can be used to know the current status of the bonding device. A camera can also be installed on the frame 1, and the bonding situation can be observed in real time through the display screen 104, or other information about the bonding device can be obtained through the display screen 104.

[0027] The movable frame 3 is mounted on the frame 1 , and the rotating mechanism 2 is mounted on the movable frame 3 . The movable frame 3 drives the rotating mechanism 2 to move along the X-axis and the Y-axis, thereby moving the rotating mechanism 2 to a corresponding position on the plane.

[0028] The rotating mechanism 2 is provided with an adsorption block 209 for adsorbing the conductive foam. The conductive foam is relatively light, so the conductive foam can be adsorbed and moved by negative pressure adsorption.

[0029] There are multiple places where the conductive foam needs to be pasted, which may be the side facing the rotating mechanism 2 or the side of the electronic product. Therefore, the rotating mechanism 2 is used to rotate the adsorption block 209 so that it can be pasted in multiple directions.

[0030] The rotating mechanism 2 includes a first-axis rotating assembly and a second-axis rotating assembly. The first-axis rotating assembly is used to control the second-axis rotating assembly to rotate along a first direction. The adsorption block 209 is installed on the second-axis rotating assembly. The adsorption block 209 is connected to the adsorption head 210, and the adsorption head 210 is arranged at the lower part of the adsorption block 209. The second-axis rotating assembly is used to control the rotation of the workpiece along a second direction perpendicular to the first direction. In this embodiment, the first direction is the transmission direction of the conveyor belt 102, and the second direction is the height direction of the bonding device, that is, the first-axis rotating assembly drives the second-axis rotating assembly to rotate as a whole along the horizontal direction, so that the adsorption block 209 can rotate 90°, and the second-axis rotating assembly enables the adsorption block 209 to achieve 360° rotation in the same plane, meeting various requirements for bonding conductive foam.

[0031] The movable frame 3 is provided with a first slide 201, which is mounted on the movable frame 3 in the X-axis direction, and the movable frame 3 in the X-axis direction is mounted on the movable frame 3 in the Y-axis direction. A second slide 202 is mounted on the first slide 201, and the second slide 202 slides with the first slide 201. A lifting mechanism 225 and a slide rail are provided on the first slide 201, and the second slide 202 slides with the slide rail. The lifting mechanism 225 controls the raising and lowering of the second slide 202.

[0032] A mounting plate 203 is mounted on the second slide 202. The first-axis rotating assembly is fixedly mounted on the mounting plate 203, and the second-axis rotating assembly is rotatably mounted on the mounting plate 203. In some embodiments, three mounting plates 203 are provided on the second slide 202, and the first-axis rotating assembly is mounted on one of the mounting plates 203. The first-axis rotating assembly includes a first power source 204 and a coupling 205 connected to the output end of the first power source 204. The central mounting plate 203 provides support for the coupling 205. The fixed end of the first power source 204 is mounted on the mounting plate 203, and the coupling 205 is located between the output end of the first power source 204 and the second-axis rotating assembly. The coupling 205 is mounted on the mounting plate 203 and is connected to the second-axis rotating assembly.

[0033] The second axis rotation assembly includes a mounting base 206 and a second power source 207 mounted on the mounting base 206. The entire mounting base 206 is rotatably connected to the mounting plate 203 and can rotate relative to the mounting plate 203. A coupling 205 is connected to the mounting base 206. The output end of the second power source 207 rotates vertically. A linkage 208 is mounted on the output end of the second power source 207. The linkage 208 can rotate 360 ​​degrees in one direction. An adsorption block 209 is mounted on the side of the linkage 208 away from the second power source 207.

[0034] like Figure 3As shown, a plurality of connection holes 226 are provided on the circumference of the linkage 208, and the adsorption block 209 is connected to the connection holes 226. Since the adsorption block 209 uses negative pressure suction to adsorb the conductive foam, if an air pipe is directly connected to the adsorption block 209, the air pipe will also rotate when the linkage 208 rotates, and the air pipe may be entangled and even worn. Therefore, an air inlet 211 is provided on the side of the linkage 208, and an air outlet 212 is provided at the bottom of the linkage 208 on the side away from the second power 207. An air duct is provided inside the linkage 208, and the air duct connects the air inlet 211 and the air outlet 212. The air pipe is connected to the air inlet 211. The linkage member 308 consists of three parts. The upper portion of the linkage member 208 is connected to the base 206 and does not rotate. The lower portion of the linkage member 208 is connected to the upper portion through the middle portion. The lower portion of the linkage member 208 rotates relative to the base 206, while the upper portion of the linkage member 208 does not rotate relative to the mounting base 206. The lower portion of the linkage member 208 rotates with the rotation of the output shaft of the second power source 207. Gas enters the airway through the air inlet 211 and then enters the adsorption block 209 through the air outlet 212.

[0035] Specifically, to accurately and in real time acquire the position data of the output shaft of the second power source 207, the present application employs a sophisticated sensing system. In this system, a first sensing block 213 is fixedly mounted on the exterior of the output shaft of the second power source 207. As the output shaft of the second power source 207 rotates, the first sensing block 213 also rotates synchronously. A first sensor 214, compatible with the first sensing block 213, is mounted on the mounting base 206 to detect changes in the position of the first sensing block 213.

[0036] Specifically, one or more sensing holes, or notches or other markings, can be evenly distributed on the first sensing block 213. These characteristic points serve as a reference for position identification. The first sensor 214 can be a through-beam photoelectric sensor. This type of sensor consists of a transmitter and a receiver, which are positioned opposite each other. When there are no obstacles between them, light can travel directly from the transmitter to the receiver, forming a closed loop. However, when there is an obstruction, the light path is interrupted, triggering a signal change.

[0037] When the output shaft of the second power unit 207 drives the first sensing block 213 to rotate to a specific angle, if the sensing hole is located in the detection path of the beam sensor, light is allowed to pass through, and the sensor receiving end will receive a signal, indicating that the output shaft of the second power unit 207 has reached one of the predetermined positions. Conversely, if the sensing hole is not in this path, meaning that the light path is blocked, the sensor will not generate a corresponding signal. In this way, it is possible to accurately locate and track different points during the rotation of the output shaft of the second power unit 207, thereby providing the necessary feedback information for subsequent control logic, supporting more efficient and accurate power management.

[0038] Similarly, in order to obtain the rotation status of the entire second-axis rotating assembly in real time, a second sensor 216 and a third sensor 217 are installed on the outer side of the mounting plate 203 away from the first-axis rotating assembly, and a second sensing block 215 is installed on the outer side of the rotating shaft of the corresponding mounting base 206. The second sensing block 215 rotates with the rotation of the coupling 205 and the second-axis rotating assembly, as shown in FIG. Figure 2 As shown, the second sensor 216 and the third sensor 217 are arranged at 90 degrees. When the second-axis rotation component fits the foam, it either fits the horizontal surface or the vertical side surface. Therefore, the second sensor 216 is used to detect the position of the second-axis rotation component when it fits the horizontal surface, and the third sensor 217 is used to detect the position of the second-axis rotation component when it fits the vertical side surface.

[0039] like Figure 3 As shown, after the entire first-axis rotating assembly rotates, the linkage 208 and the adsorption block 209 on the second-axis rotating assembly rotate toward the second slide 202, which may cause interference. Therefore, an arc-shaped avoidance opening 219 is provided at the bottom of the second slide 202. The avoidance opening 219 is located between the mounting plates 203 corresponding to the position of the second-axis rotating assembly, that is, the avoidance opening 219 is provided between the middle mounting plate 203 and the mounting plate 203 away from the first power 204.

[0040] Since the mounting base 206 is connected to the output shaft of the first power 204 via the coupling 205, the mounting base 206 rotates during use. The mounting base 206 is provided with a second shaft transmission assembly having a certain weight, and the weight of the upper and lower ends of the mounting base 206 is different, which may cause shaking during rotation. Therefore, in order to ensure that the mounting base 206 can rotate smoothly and not shake during rotation, a guide block 218 is installed on one or both sides of the outer side surface of the mounting base 206. The guide block 218 is arc-shaped, and the arc-shaped inner wall of the guide block 218 contacts the end of the mounting plate 203. The arc length and radius of the guide block 218 are reasonably designed so that the arc-shaped inner wall of the guide block 218 remains in contact with the end of the mounting block as the mounting base 206 rotates relative to the mounting plate 203, providing a rotation guide for the entire mounting base 206 through the end of the mounting plate 203.

[0041] The first and second axis rotating assemblies are wired to the controller and connected to the air supply via air pipes. To prevent wear and tear on the wiring harness and air pipes, a first wiring harness fixing plate 220 is located on the side of the first slide 201 facing away from the second slide 202. A first wiring harness fixing hole 221 is defined in the first wiring harness fixing plate 220, through which the wiring harness and air pipes are threaded and secured. A second wiring harness fixing plate 222 is located on the second slide 202, with a second wiring harness fixing hole 223 defined in the second wiring harness fixing plate 222. A tank chain is installed on the mobile frame 3. The wiring harness and air pipes pass through the tank chain and then through the second wiring harness fixing hole 223, where they are partially connected to the lifting power 225. The remaining portion then passes through the first wiring harness fixing hole 221, ultimately connecting to the first and second axis rotating assemblies. To facilitate wiring harness replacement and operation, notches 224 are provided in both the first wiring harness fixing hole 221 and the second wiring harness fixing hole 223.

[0042] Working process: After the product is transported to the workbench by the conveyor belt 102, the mobile frame 3 moves to the edge of the workbench 101 to adsorb the conductive foam, and then moves into position. If it is to fit the horizontal surface, the lifting power 225 can be directly lowered to fit. If it is to fit the side, the first power 204 rotates the second axis rotation assembly 90° counterclockwise, and then according to the fitting surface, the second power 207 rotates the position of the adsorption block 209 for fitting.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
