DETAILED DESCRIPTION

[0022] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0023] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 5As shown, an embodiment of the utility model provides a clamping device for producing bonding gold wires, including a clamping assembly 2 for producing bonding gold wires, the clamping assembly 2 includes a splint 209, a plurality of splints 209 are provided, each splint 209 is provided with a pressure sensing assembly 3, the pressure sensing assembly 3 includes an air cushion 301, the air cushion 301 is fixed on the inner side of the splint 209, a transmission tube 302 is fixedly connected inside the splint 209, one end of the transmission tube 302 is fixedly connected to the air cushion 301, and the other end of the transmission tube 302 is fixedly connected to an air bag 303, the splint 209 is fixedly connected to the outside of the splint 204, a limit switch 305 is fixedly installed on the upper part of the mounting plate 304, and the lower part of the limit switch 305 is in contact with the air bag 303.

[0025] The above-mentioned bonding wire clamping device can achieve precise clamping force control by introducing the components of the air cushion 301 and the air bag 303, thereby avoiding the problem of bonding wire breakage or loose clamping due to improper clamping force.

[0026] Specifically, when the user places the bonding wire between the clamping assembly 2 and the clamping plate 209, the air cushion 301 on the clamping plate 209 will be subjected to external force, so that the gas in the air cushion 301 is squeezed. The air pressure will be transmitted to the air bag 303 connected to the air cushion 301 through the transmission tube 302, and the air bag 303 will gradually expand. When the air bag 303 expands to a certain extent, the limit switch 305 is triggered to sense the expansion state of the air bag 303, thereby stopping the continued clamping of the bonding wire. In this way, through the cooperation of the air cushion 301 and the air bag 303, the clamping device can accurately control the clamping force according to the diameter and material properties of the bonding wire, avoiding damage to the bonding wire or loose clamping.

[0027] In this embodiment, the clamping assembly 2 also includes an electric push rod 201 for fixing on an object, the output end of the electric push rod 201 is fixedly connected to a mounting seat 202, and the outside of the mounting seat 202 is fixedly connected to a support frame 205. A second motor 203 is fixedly installed inside the mounting seat 202, and a screw rod 204 is fixedly connected to the output end of the second motor 203, and a slider 207 is screwed to the outside of the screw rod 204. The slider 207 is rotatably connected to a connecting plate 208 on the outside, and the side of the connecting plate 208 away from the slider 207 is fixedly connected to a clamping plate 209. The outside of the support frame 205 is fixedly connected to a sliding rod 206, and the outside of the sliding rod 206 is slidably connected to the clamping plate 209.

[0028] First, the user controls the electric push rod 201 to move the clamping plate 209 to the area where clamping is required, and places the bonding wire to be processed between the clamping plates 209. The second motor 203 inside the clamping assembly 2 drives the screw 204 to rotate, and the rotation of the screw 204 drives the slider 207 to move backward on the support frame 205, guiding the movement of the clamping plate 209. The slider 207 is connected to a connecting plate 208 on the outside, and the connecting plate 208 is fixedly connected to the clamping plate 209 on the side away from the slider 207. When the screw 204 moves backward, the driving of the connecting plate 208 causes the three clamping plates 209 to perform a clamping action at the same time to clamp the bonding wire. During the clamping action, the slide bar 206 acts as a guide structure to ensure the smooth sliding of the clamping plate 209, avoid deflection or unevenness during the clamping process, and ensure the accuracy and stability of the clamping. Thereby, the position and clamping force of the clamping plate 209 can be accurately controlled to ensure that the bonding wire is firmly clamped without damage or looseness when processing.

[0029] In this embodiment, the bonding wire clamping device further includes a guide transmission assembly 1, which includes a guide tube 101, which is movably plugged with the clamping plate 209, and a channel for transmitting bonding wire is provided inside the guide tube 101. A rotating wheel 102 is rotatably installed inside the guide tube 101, and two rotating wheels 102 are provided. A first motor 103 is fixedly installed on the upper part of the guide tube 101, and the output end of the first motor 103 is fixedly connected to one of the rotating wheels 102. The rotating wheel 102 consists of a wheel body 1021 and a rubber ring 1022. The wheel body 1021 is rotatably installed inside the guide tube 101, and the rubber ring 1022 is sleeved and installed on the upper part of the wheel body 1021.

[0030] The user controls the first motor 103 to drive the rotating wheel 102 on the guide tube 101 to rotate, and the movement of the rotating wheel 102 drives the bonding gold wire to be transmitted along the channel inside the guide tube 101. When the bonding gold wire is transmitted to the clamping area of ​​the guide tube 101, the user operates the electric push rod 201 to move the clamping plate 209 to the area for plugging and clamping the bonding gold wire. After the clamping action is completed, the electric push rod 201 drives the mounting seat 202 to move backward so that the bonding gold wire guide is taken out. At the same time, the second motor 203 reverses to control the clamping plate 209 to expand outward and release the clamping. Accurate transmission and clamping of the bonding gold wire is achieved. The first motor 103 drives the rotating wheel 102 to drive the bonding gold wire to move, and the second motor 203 controls the clamping and release of the clamping plate 209, ensuring the accuracy and stability of the bonding gold wire operation.

[0031] The working principle of this utility model:

[0032] When the user places the bonding gold wire between the clamping assembly 2 and the clamping plate 209, the air cushion 301 on the clamping plate 209 will be subjected to external force, causing the gas in the air cushion 301 to be squeezed. The air pressure will be transmitted to the air bag 303 connected to the air cushion 301 through the transmission tube 302, and the air bag 303 will gradually expand. When the air bag 303 expands to a certain extent, the limit switch 305 is triggered to sense the expansion state of the air bag 303, thereby stopping the continued clamping of the bonding gold wire. In this way, through the cooperation of the air cushion 301 and the air bag 303, the clamping device can accurately control the clamping force according to the diameter and material properties of the bonding gold wire, avoiding damage to the bonding gold wire or loose clamping.
