Description

Technical Field

[0001] This invention relates to the technical field of terminal testing, and more particularly to an automatic terminal testing device for an assembly machine. Background Technology

[0002] Electrical connectors are the basic components for electrical connection and signal transmission between devices, components, and systems. Because of their good contact, reliable operation, and convenient maintenance, they are widely used in various electrical circuits to connect or disconnect circuits.

[0003] When assembling connector terminals, it is common for the terminal tip to be not firmly inserted, making it easy to detach during use. In the current technology, there is no way to perform automated flow inspection of the terminals. Manual inspection or machine inspection may damage the terminals due to excessive inspection force or forcibly pull out the terminals. Therefore, there is a need for a device that can identify poorly assembled terminals while ensuring that the inspection process does not damage the terminals or forcibly pull out well-assembled terminals. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic terminal assembly and testing device for an assembly machine, which addresses the shortcomings of existing technologies and achieves the effect of automatically testing terminals without damaging them during the testing process.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] An automatic terminal assembly detection device for an assembly machine includes a device body, a drive cylinder, a pneumatic support device, a linear guide mechanism, a gripper fixing device, a gripper mechanism, a blocking component, and a pressure sensing device. The drive cylinder is positioned above the device body. The gripper fixing device and the pneumatic support device are respectively fixed to the left and right sides of the device body. The pressure sensing device is positioned between the gripper fixing device and the pneumatic support device. The linear guide mechanism is disposed on the surface of the device body and includes a slider and a slide rail. The slider is slidably fixed above the slide rail and is mutually fixed to the gripper fixing device. The slide rail is fixed to the device body. A laser displacement sensor is disposed on the outside of the device body, and a laser displacement sensor is disposed on the outside of the gripper fixing device. The laser displacement sensor and the laser displacement sensor are disposed on the same side. The gripper mechanism is fixedly connected below the gripper fixing device to sense a fixed distance from the gripper fixing device by the laser displacement sensor and the laser displacement sensor, thereby detecting whether the terminal is installed in place based on the distance result.

[0007] Furthermore, the drive cylinder also includes a first drive link, a second drive link, and a third drive link to provide route support for the gripper to move in three directions.

[0008] Furthermore, it also includes a blocking member, the bottom end of which is fixed to the outside of the device body, and the top end of which abuts against the path of the gripper fixing device moving outward from the device body, so as to limit the movement path of the gripper fixing device and prevent it from accidentally falling off.

[0009] Furthermore, the blocking member also includes a telescopic buffer mechanism and a blocking mechanism. One end of the telescopic buffer mechanism is disposed at the top of the blocking member, and the blocking mechanism is disposed at the other end of the telescopic buffer mechanism. The blocking mechanism abuts against the gripper fixing device to better limit the movement path of the gripper fixing device.

[0010] Furthermore, the pressure sensing device is a pull-out force sensor, and the surface of the pull-out force sensor is also provided with adjustment and fixing holes to stabilize the force transmission between the pull-out force sensor and the pneumatic support device.

[0011] Furthermore, the pneumatic support device also includes a pneumatic support rod and a pneumatic support length adjustment device, wherein the pneumatic support length adjustment device is disposed on the pneumatic support rod, and the pneumatic support rod abuts against the gripper fixing device.

[0012] Furthermore, the gripper mechanism is also provided with a gripper connector and a gripper, and the gripper is fixed to the gripper fixing device through the gripper connector.

[0013] Furthermore, the inner surface of the gripper is also provided with gripper ridges for more stable clamping and fixing of the terminal.

[0014] The technical solution of this invention can achieve the following technical effects:

[0015] The device comprises a main body, a drive cylinder, a pneumatic support device, a linear guide mechanism, a gripper fixing device, a gripper mechanism, a blocking component, and a pressure sensing device. The drive cylinder is positioned above the main body. The gripper fixing device and the pneumatic support device are fixed to the left and right sides of the main body, respectively. The pressure sensing device is positioned between the gripper fixing device and the pneumatic support device. The linear guide mechanism is located on the surface of the main body and includes a slider and a slide rail. The slider is slidably fixed above the slide rail, and the slider is mutually fixed to the gripper fixing device. The slide rail is fixed to the main body. A laser displacement sensor is located on the outside of the main body, and a laser displacement sensor is located on the outside of the gripper fixing device, both on the same side.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Therefore, they should not be construed as limitations on this invention.

[0029] An automatic terminal assembly detection device for an assembly machine, such as Figure 1 and 3 As shown, the device includes a main body 1, a drive cylinder 2, a pneumatic support device 3, a linear guide mechanism 4, a gripper fixing device 5, a gripper mechanism 6, a blocking component 7, and a pressure sensing device 8. The drive cylinder 2 is located above the main body 1. The gripper fixing device 5 and the pneumatic support device 3 are respectively fixed on the left and right sides of the main body 1. The pressure sensing device 8 is located between the gripper fixing device 5 and the pneumatic support device 3. The linear guide mechanism 4 is located on the surface of the main body 1. The linear guide mechanism 4 includes a slider 41 and a slide rail 42. The slider 41 is slidably fixed above the slide rail 42. The slider 41 is fixed to the gripper fixing device 5. The slide rail 42 is fixed to the main body 1. A laser displacement sensor 9 is provided on the outside of the main body 1. A laser displacement sensor 91 is provided on the outside of the gripper fixing device 5. The laser displacement sensor 91 and the laser displacement sensor 9 are located on the same side. The gripper mechanism 6 is fixedly connected to the bottom of the gripper fixing device 5.

[0030] Specifically, the drive cylinder 2 is positioned above the device body 1 to support its displacement. A pressure sensing device 8 is positioned between the gripper fixing device 5 and the pneumatic support device 3. The gripper fixing device 5 and the pneumatic support device 3 are respectively fixed to the left and right sides of the device body 1, ensuring that the pneumatic support device 3 applies pressure to the pressure sensing device 8. The pressure sensing device 8 detects whether the force provided by the pneumatic support device 3 exceeds a predetermined force, thus preventing damage to the terminals. The presence of the blocking member 7 prevents the gripper fixing device 5 from moving. After the change, the drive cylinder 2 drives the gripper mechanism 6 to complete the action of picking up the material and fixing the front end of the terminal. At this time, the terminal will not be subjected to the force of the pneumatic support device 3, and the poorly connected terminal will not be pulled out. When the gripper mechanism 6 completes the action of fixing the front end of the terminal, it will first perform a pre-insertion on the terminal shell, and then the gripper will open and then close to perform a second insertion to ensure the insertion stability. After completing the two insertion actions, the gripper remains fixed, and the drive cylinder 2 drives the device body 1 to move in the opposite direction of the terminal insertion direction. At this time, the force applied by the drive cylinder 2 drives the device body 1 and the pneumatic support device 3. As the support device 3 and laser displacement sensor 9 move outward, the linear guide mechanism 4, including slider 41 and slide rail 42, with slide rail 42 fixed to the device body 1, allows the device body 1, pneumatic support device 3, and laser displacement sensor 9 to move outward along with slide rail 42. Due to the gas support characteristics of the pneumatic support device 3 and the non-deformable characteristic of the pressure sensing device 8, an outward pulling force, not exceeding the predetermined force provided by the pneumatic support device 3, is transmitted from the pneumatic support device 3 to the gripper fixing device 5 and then to the terminal connection. This force is used to detect whether the terminal connection is... The device is pulled out, and the detection result is provided by the change in distance between the laser displacement sensor 9 and the laser displacement sensing element 91. When the terminal connection is intact, the position of the gripper fixing device 5 remains unchanged because the terminal connection is intact, and the slide rail 42 moves outward within the fixed slider 41. The relative distance between the laser displacement sensor 9 and the laser displacement sensing element 91 will shorten accordingly, reaching the predetermined relative distance after movement. When the relative distance between the laser displacement sensor 9 and the laser displacement sensing element 91 remains unchanged, or does not conform to the predetermined relative distance after movement, it is judged that the terminal connection is faulty. In the actual implementation of the device, the force set by the pneumatic support device 3 is generally 10N, and different presets can be changed according to different terminals.

[0031] As a preferred embodiment of the above, such as Figure 6 As shown, the drive cylinder 2 also includes a first drive link 21, a second drive link 22 and a third drive link 23.

[0032] Specifically, the drive cylinder 2 also includes a first drive link 21, a second drive link 22 and a third drive link 23, which are used to drive the device body 1 and the gripper fixing device 5 to complete terminal connection tests, terminal insertion and material handling operations, respectively.

[0033] As a preferred embodiment of the above, such as Figure 7 As shown, it also includes a blocking member 7, the bottom end of which is fixed to the outside of the device body 1, and the top end of which abuts against the path of the gripper fixing device 5 moving outward from the device body 1.

[0034] Specifically, the bottom end of the blocking member 7 is fixed to the outside of the device body 1, and the top end of the blocking member 7 abuts against the path of the gripper fixing device 5 moving outward from the device body 1. This structure blocks the force applied to the gripper fixing device 5 by the pneumatic support device 3 before the drive cylinder 2 drives the device body 1 to perform the test action of pulling outward.

[0035] As a preferred embodiment of the above, as shown in 4, the blocking member 7 further includes a telescopic buffer mechanism 71 and a blocking mechanism 72. One end of the telescopic buffer mechanism 71 is disposed at the top of the blocking member 7, and the blocking mechanism 72 is disposed at the other end of the telescopic buffer mechanism 71. The blocking mechanism 72 abuts against the gripper fixing device 5.

[0036] Specifically, one end of the telescopic buffer mechanism 71 is located at the top of the blocking member 7, and the blocking mechanism 72 is located at the other end of the telescopic buffer mechanism 71. The blocking mechanism 72 abuts against the gripper fixing device 5 to better block the force applied to the gripper fixing device 5 by the pneumatic support device 3 in the initial state. After the drive cylinder 2 drives the device body 1 to perform a test action of pulling outward, when resetting, the existence of the telescopic buffer mechanism 71 ensures that the blocking mechanism 72 will not cause rigid damage to the gripper fixing device 5.

[0037] As a preferred embodiment of the above, such as Figure 1 As shown, the pressure sensing device 8 is a pull-out force sensor 81, and the surface of the pull-out force sensor 81 is also provided with adjustment and fixing holes 82.

[0038] As a preferred embodiment of the above, such as Figure 8 As shown, the pneumatic support device 3 also includes a pneumatic support rod 31 and a pneumatic support length adjustment device 32. The pneumatic support length adjustment device 32 is mounted on the pneumatic support rod 31, and the pneumatic support rod 31 abuts against the gripper fixing device 5.

[0039] Specifically, the pressure sensing device 8 is a pull-out force sensor 81. The surface of the pull-out force sensor 81 is also provided with an adjustment and fixing hole 82. The pneumatic support length adjustment device 32 is set on the pneumatic support rod 31. The pneumatic support rod 31 is abutted against the clamp fixing device 5. The pneumatic support rod 31 is supported on the adjustment and fixing hole 82, which can better maintain the stability of the connection in the initial state and better transmit the outward pulling force during the test action. The pneumatic support length adjustment device 32, together with the characteristics of the pneumatic support device 3 itself, adjusts the preset force to achieve the detection of different tolerable outward pulling forces for different terminals.

[0040] As a preferred embodiment of the above, such as Figure 5 As shown, the gripper mechanism 6 is further provided with a gripper connector 61 and a gripper 62, and the gripper 62 is fixed to the gripper fixing device 5 through the gripper connector 61.

[0041] Specifically, the gripper mechanism 6 is also provided with a gripper connector 61 and a gripper 62. The gripper 62 is fixed to the gripper fixing device 5 through the gripper connector 61, so that the gripper connector 61 can quickly replace the gripper 62 or adjust the relative height of the gripper 62.

[0042] As a preferred embodiment of the above, such as Figure 4 As shown, the inner surface of the gripper 62 is also provided with a gripper ridge surface 621.

[0043] Specifically, the inner surface of the gripper 62 is also provided with a gripper ridge 621, so that the gripper 62 can better fix and grip the terminal.

[0044] Specifically, the device comprises a main body, a drive cylinder, a pneumatic support device, a linear guide mechanism, a gripper fixing device, a gripper mechanism, a blocking component, and a pressure sensing device. The drive cylinder is positioned above the main body. The gripper fixing device and the pneumatic support device are fixed to the left and right sides of the main body, respectively. The pressure sensing device is positioned between the gripper fixing device and the pneumatic support device. The linear guide mechanism is positioned on the surface of the main body and includes a slider and a slide rail. The slider is slidably fixed above the slide rail, and the slider is fixed to the gripper fixing device. The slide rail is fixed to the main body. A laser displacement sensor is positioned on the outside of the main body, and a laser displacement sensor is positioned on the outside of the gripper fixing device. The laser displacement sensor and the laser displacement sensor are positioned on the same side. The gripper mechanism is fixedly connected below the gripper fixing device. This structure solves the problems in the prior art where it is impossible to automatically detect whether the connection at the front end of the terminal is in place, and where the detection action may damage the terminal, and the damage cannot be identified.
