Description

Technical Field

[0001] This utility model relates to the technical field of detection devices in pressing production, and in particular to a tooling for detecting the position of a tooling on a conveyor chain. Background Technology

[0002] Wire bonding refers to the production of chip products, specifically chip bonding and film coating, also known as bonding. It is a wire bonding method in chip manufacturing, generally used to connect the internal circuitry of the chip to the package pins using gold wires before packaging.

[0003] To further enhance automation, in Bonding line product production, the parts to be pressed are usually placed on a conveyor chain, and then transported to the pressing station by the conveyor chain to automatically complete the pressing process of the parts to be pressed.

[0004] However, the prolonged mechanical relative movement of the pressing fixture can lead to localized wear of mechanical parts. When the wear is high, the relative position between the upper and lower molds of the pressing fixture will gradually shift, causing the product to shift during gluing and pressing, and ultimately causing the glue line to shift. When the glue line shift exceeds 0.5mm, poor product bonding will occur, leading to product rework, scrapping, or even the risk of product failure at the customer's end. Such poor bonding is difficult to detect in time during the production process. Utility Model Content

[0005] In view of the above problems, this utility model provides a tooling for detecting the position of a tooling on a conveyor chain, the purpose of which is to ensure pressing accuracy and improve customer satisfaction.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0007] A tooling for detecting the position of a tooling on a conveyor chain is provided, comprising: a mounting bracket disposed on one side of the conveyor chain; a six-axis industrial robot disposed on one side of the conveyor chain for gripping and pressing a pressing tooling; a first detection component disposed on the mounting bracket for detecting the coordinates of the upper die of the pressing tooling in the X direction; a second detection component disposed on the mounting bracket for detecting the coordinates of the upper die of the pressing tooling in the Y direction; a third detection component disposed on the conveyor chain for detecting the coordinates of the upper die of the pressing tooling in the X direction; a fourth detection component disposed on the conveyor chain for detecting the coordinates of the lower die of the pressing tooling in the Y direction; and a control component electrically connected to the first detection component, the second detection component, the third detection component, the fourth detection component, and the six-axis industrial robot.

[0008] Furthermore, the testing fixture also includes: a guide rail, fixedly mounted on the ground; a mounting base, slidably mounted on the guide rail, and a mounting bracket fixedly mounted on the mounting base; and a linear drive component for driving the mounting base to slide along the guide rail.

[0009] Furthermore, the testing fixture also includes: a rotary cylinder, the main body of which is fixedly mounted on a mounting bracket; a turntable mounted on the rotating shaft of the rotary cylinder; and two pairs of first and second testing components, which are centrally symmetrically arranged on the turntable with the rotating shaft of the rotary cylinder as the center.

[0010] Furthermore, a notch is provided on the turntable for placing the pressing tool.

[0011] Furthermore, the first, second, third, and fourth detection components are all dial indicators.

[0012] Furthermore, the testing fixture also includes: a mounting block, which is detachably mounted on a mounting bracket by screws, and a dial indicator is detachably mounted inside the mounting block by a threaded connection.

[0013] The beneficial effects of this utility model are as follows: by using this utility model, the actual coordinates of the upper and lower dies can be detected separately before the pressing work is carried out by the pressing tooling. It can be determined whether the relative error between the upper and lower dies meets the tolerance requirements, which can provide a theoretical basis for subsequent pressing work, ensure the subsequent pressing accuracy, ensure that the product quality meets the production standards, and improve customer satisfaction.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] This application discloses a tooling for detecting the position of a tooling on a conveyor chain, comprising: a mounting bracket 1 disposed on one side of the conveyor chain; a six-axis industrial robot disposed on one side of the conveyor chain for gripping and pressing a pressing tooling; a first detection component 21 disposed on the mounting bracket 1 for detecting the coordinates of the upper mold 6 of the pressing tooling in the X direction; a second detection component 22 disposed on the mounting bracket 1 for detecting the coordinates of the upper mold 6 of the pressing tooling in the Y direction; a third detection component disposed on the conveyor chain for detecting the coordinates of the upper mold 6 of the pressing tooling in the X direction; a fourth detection component disposed on the conveyor chain for detecting the coordinates of the lower mold of the pressing tooling in the Y direction; and a control component electrically connected to the first detection component 21, the second detection component 22, the third detection component, the fourth detection component, and the six-axis industrial robot.

[0020] Reference Figure 1 As shown, the conveyor chain transports the parts to be pressed to the pressing station and then stops. A six-axis industrial robot grabs the upper mold 6 of the pressing fixture and moves it to the inspection station for inspection. At the inspection station, the outer wall surface of the upper mold 6 of the pressing fixture touches the first inspection component 21 and the second inspection component 22 to determine the coordinates of the upper mold 6 in the X and Y directions, which are then converted into electrical signals and transmitted to the control component.

[0021] In addition, the lower mold is lifted to the pressing station by a hydraulic cylinder. A third detection component and a fourth detection component (not shown in the figure) are set on the conveyor chain. The outer wall surface of the lower mold can abut against the third detection component and the fourth detection component to know the coordinates of the lower mold in the X and Y directions, and convert them into electrical signals to be transmitted to the control component. By comparing the difference between the actual coordinates and the theoretical coordinates between the upper mold 6 and the lower mold of the pressing fixture by the control component, it can be determined whether the error of the relative position between the upper mold 6 and the lower mold is within the tolerance range, providing a theoretical basis for subsequent pressing operations.

[0022] By using this invention, the actual coordinates of the upper mold 6 and the lower mold can be detected before the pressing work is carried out by the pressing tool. This allows us to know whether the relative error between the upper mold 6 and the lower mold meets the tolerance requirements, providing a theoretical basis for subsequent pressing work, ensuring the pressing accuracy, ensuring that the product quality meets the production standards, and improving customer satisfaction.

[0023] It is worth mentioning that the control component can be an industrial PC, using industrial-grade computer hardware and software to automatically determine errors.

[0024] Reference Figure 2 and Figure 3As shown, the testing fixture also includes: a guide rail 31, fixedly mounted on the ground; a mounting base 32, slidably mounted on the guide rail 31, and a mounting bracket 1 fixedly mounted on the mounting base 32; a linear drive component 33, used to drive the mounting base 32 to slide along the guide rail 31; the testing fixture also includes: a rotary cylinder 41, the main body of which is fixedly mounted on the mounting bracket 1; a turntable 42, mounted on the rotating shaft of the rotary cylinder 41; and two pairs of first testing components 21 and second testing components 22, centrally symmetrically arranged on the turntable 42 with the rotating shaft of the rotary cylinder 41 as the center.

[0025] It is worth mentioning that the upper mold 6 is grasped by an industrial six-axis robot and is in a suspended state. Compared with the lower mold, the positioning accuracy of the upper mold 6 needs to be more precise. In specific use, the upper mold 6 is first inspected by one pair of first detection components 21 and second detection components 22 on the turntable 42. Then, the linear drive component 33 drives the mounting base 32 away from the upper mold 6 and drives the turntable 42 to rotate 180°. Finally, the linear drive component 33 drives the mounting base 32 closer to the upper mold 6, and the other pair of first detection components 21 and second detection components 22 on the turntable 42 inspect the upper mold 6. By using this utility model, the upper mold 6 can be inspected twice, which further improves the accuracy of the inspection.

[0026] In this embodiment, the linear drive component 33 is an electric actuator, the main body of which is fixedly mounted on the ground, and the actuator is connected to the mounting base 32.

[0027] Preferably, a notch 43 is provided on the turntable 42 for placing the pressing tool.

[0028] Furthermore, the first detection component 21, the second detection component 22, the third detection component, and the fourth detection component are all dial gauges.

[0029] It is worth mentioning that the dial indicator can be a digital dial indicator, powered by a button battery.

[0030] Preferably, the testing fixture further includes: a mounting block 5, which is detachably mounted on the mounting bracket 1 by screws, and a dial indicator is detachably mounted inside the mounting block 5 by threaded connection.
