Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and more specifically, to a part flipping detection device. Background Technology

[0002] A cylindrical part is available, comprising a sleeve and an end plate fitted onto the sleeve. The end plate is larger than the outer diameter of the sleeve and is integrally formed with the sleeve, resulting in a part with one large end and one small end. A hole is formed on the outer wall of one side of the end plate. During production, workers place the blank part on a conveyor to the next processing station. Due to the conveyor's structure, the smaller end of the part (the end furthest from the end plate) faces downwards. However, the next processing station requires the larger end of the part to face downwards. Therefore, a part-turning device is installed at the tail end of the conveyor to rotate the part 180 degrees, so that the larger end faces downwards. However, the next processing station requires the holes on the part to face the same direction. Since the part is manually placed on the conveyor, the holes tend to be misaligned. The part-turning device only rotates the part 180 degrees, requiring manual adjustment at the next processing station. Manual adjustment has a large error margin and is labor-intensive. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model provides a part flipping detection device, comprising a base plate, a flipping clamping drive component mounted on the base plate, a rotation drive component, and a detection component. The flipping clamping drive component clamps and flips the part. The rotation drive component is slidably connected to the base plate in the vertical direction. The rotation drive component is adapted to receive the flipped part and drive the part to rotate. The detection component is connected to the rotation drive component and moves synchronously in the vertical direction. The detection component is adapted to detect the position of holes on the part.

[0004] Optionally, the flipping clamping drive includes a flipping cylinder and a clamping cylinder. The flipping cylinder is connected to the substrate, and the flipping cylinder is connected to the clamping cylinder to drive the clamping cylinder to flip, and the clamping cylinder clamps or releases the part.

[0005] Optionally, a lifting drive component is mounted on the base plate, and the lifting drive component is connected to the rotation drive assembly to drive the rotation drive assembly to move up and down.

[0006] Optionally, the lifting drive component is a magnetically coupled rodless cylinder.

[0007] Optionally, the rotation drive assembly includes a mounting frame and a rotary clamping electric cylinder. The mounting frame is connected to the lifting drive component, and the rotary clamping electric cylinder is connected to the mounting frame and moves synchronously. The rotary clamping electric cylinder is adapted to internally clamp the part and drive the part to rotate.

[0008] Optionally, the rotary clamping electric cylinder includes a motor, a connector, and a rotating component connected in sequence. The rotating component is located on top of the connector. The motor can drive the rotating component to rotate. The top of the rotating component is provided with a three-jaw gripper. The three-jaw gripper is adapted to expand or contract. The three-jaw gripper is adapted to be inserted into the part to open and clamp or contract and release the part.

[0009] Optionally, the detection assembly is mounted on the mounting frame. The detection assembly includes a mounting plate, a slide cylinder, and a sensor. The mounting plate is mounted on the top of the mounting frame. The slide cylinder is connected to the mounting plate. The sensor is connected to the slide cylinder. The slide cylinder drives the sensor to move closer to or away from the rotary clamping electric cylinder. The sensor is used to detect the position of a hole on the part. The rotary clamping electric cylinder drives the part to rotate so that the hole faces the sensor.

[0010] Optionally, the position of the mounting plate can be adjusted forward and backward and locked.

[0011] Optionally, a slider is provided on the mounting plate in the vertical direction, and a linkage plate is provided on the slider. The linkage plate slides synchronously with the slider. The slide cylinder is connected to the linkage plate and slides synchronously in the vertical direction. A limit bolt for locking or unlocking the linkage plate is threaded on the mounting plate.

[0012] Optionally, the linkage plate has an oblong hole that extends in the vertical direction. The limiting bolt is inserted into the oblong hole and threadedly connected to the mounting plate. The limiting bolt is adapted to press and limit the linkage plate to the mounting plate.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] 1. After the flipping clamping drive unit flips the part, the rotation drive assembly can receive and clamp the part, and the detection assembly can detect the position of the hole on the part. During the detection process, the rotation drive assembly can drive the part to rotate so that the hole faces the specified position and is detected by the detection assembly, reducing manual operation. At the same time, the rotation adjustment detection accuracy is high, improving the accuracy of the hole direction of each part to be consistent.

[0015] 2. When the flipping clamping drive unit flips the part, the lifting drive unit can drive the rotation drive component to move down to avoid collisions due to interference. When the part hole position is detected and rotated for adjustment, the flipping clamping drive unit can flip the next part from above, which improves work efficiency.

[0016] 3. Compared to the three-jaw gripper holding the outside of the part, the three-jaw gripper inserts into the inside of the part to provide internal support and clamping. No matter which position the hole of the part faces after flipping, the three-jaw gripper will not block the hole from the outside, thus affecting the detection of the detection component and improving the accuracy of rotation adjustment detection.

[0017] 4. The mounting plate can be adjusted in the front-to-back direction, and the linkage plate can be adjusted in the up-to-down direction, making it suitable for parts of different sizes and heights, with a wide range of applications. Attached Figure Description

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-4 This application will be described in further detail.

[0024] The accompanying drawings of this utility model embodiment provide a coordinate system XYZ, where the positive direction of the X-axis represents the right, the negative direction of the X-axis represents the left, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0025] This utility model provides a part flipping detection device, referring to... Figure 1 The part flipping detection device includes a base plate 1, a flipping clamping drive component 2 mounted on the base plate 1, a rotation drive assembly 3, and a detection assembly 4. The rotation drive assembly 3 is located below the flipping clamping drive component 2 and is slidably connected to the base plate 1 in the vertical direction. The detection assembly 4 is connected to the rotation drive assembly 3 and moves synchronously in the vertical direction. During part production, workers place the blank part on a conveyor, and then the part is transferred to the flipping clamping drive component 2 by an industrial robot. When the part is first transferred to the flipping clamping drive component 2, the larger end of the part is facing upwards. The flipping clamping drive component 2 flips the part 180 degrees so that the larger end of the part is facing downwards. During the flipping, the rotation drive assembly 3 moves downwards to avoid interference and collision. After the part is flipped by the flipping clamping drive 2, the rotation drive assembly 3 moves upward to support the part, and then drives the part downward. The detection assembly 4 detects the position of the hole. At the same time, the control system drives the rotation drive assembly 3 to rotate the part so that the hole faces the detection assembly 4 for detection. Then, the industrial robot at the next station transfers the oriented part from the rotation inner support drive to the next processing station. The whole process reduces manual operation, and the rotation adjustment and detection accuracy is high, improving the consistency of the hole orientation of each part.

[0026] In other embodiments, the flip clamping drive 2 can flip the part by a specified angle according to the position of the rotation drive assembly 3 or the requirements of the next process. For example, the flip clamping drive 2 can flip the part by ninety degrees.

[0027] Reference Figure 1 The flipping and clamping drive unit 2 includes a flipping cylinder 21 and a clamping cylinder 22. The cylinder body of the flipping cylinder 21 is fixed to the base plate 1 by bolts, and the cylinder body of the clamping cylinder 22 is fixed to the rotating part of the flipping cylinder 21 by bolts, thereby driving the flipping cylinder 21 to rotate the clamping cylinder 22 by 180 degrees. The clamping cylinder 22 then clamps or releases the part.

[0028] A lifting drive component 11 is bolted to one side of the rotating cylinder 21 fixed to the base plate 1. The lifting drive component 11 is located below the rotating cylinder 21. The lifting drive component 11 is connected to the rotation drive assembly 3 to drive the rotation drive assembly 3 to move up and down. In this embodiment, the lifting drive component 11 is preferably a magnetically coupled rodless cylinder. The magnetically coupled rodless cylinder has high precision and can drive the rotation drive assembly 3 to accurately reach the preset position to receive the part when driving the rotation drive assembly 3 to move up and down. The rotation drive assembly 3 is mounted on the slide of the magnetically coupled rodless cylinder to achieve up and down movement. In another embodiment, the lifting drive component 11 can be a conventional telescopic cylinder, and the rotation drive assembly 3 is connected to the telescopic rod of the telescopic cylinder.

[0029] Reference Figure 1 and Figure 2 The rotation drive assembly 3 includes a mounting bracket 31 and a rotary clamping electric cylinder 32 (a prior art technology, meaning it has both the function of clamping an item and the function of driving the clamped item to rotate). The mounting bracket 31 is fixedly connected to a slide on a magnetically coupled rodless cylinder to achieve synchronous up-and-down movement. The rotary clamping electric cylinder 32 is connected to the mounting bracket 31 by bolts and moves synchronously. The rotary clamping electric cylinder 32 is suitable for internally clamping parts and driving the parts to rotate.

[0030] Reference Figure 1 and Figure 2 Specifically, the rotary clamping electric cylinder 32 includes a motor 33, a connecting member 34, and a rotating member 35 connected in sequence. The rotating member 35 is located at the top of the connecting member 34, and the motor 33 is located at the bottom of the connecting member 34. A mechanical transmission assembly is provided inside the connecting member 34. The motor shaft of the motor 33 and the rotating member 35 are both connected to the mechanical transmission assembly, thus enabling the motor 33 to drive the rotating member 35 to rotate. A three-jaw gripper 36 (i.e., three circumferentially arranged grippers) is slidably provided on the top of the rotating member 35. A micro-motor 33 gear set is provided inside the rotating member 35, and the micro-motor 33 gear set is connected to the three-jaw gripper 36, thereby driving the three-jaw gripper 36 to expand or contract. The three-jaw gripper 36 can be inserted inside the part to open and clamp or contract and release the part, thereby allowing the part to be clamped and rotated in opposite directions under the drive of the motor 33, adjusting the orientation of the hole. In another embodiment, the three-jaw gripper 36 can be located outside the part, directly clamping the outside of the part.

[0031] Reference Figure 2 and Figure 3 The detection component 4 is mounted on the top of the mounting bracket 31. The detection component 4 includes a mounting plate 41, a slide cylinder 42, and a sensor 43. The mounting plate 41 is mounted on the top of the mounting bracket 31. The slide cylinder 42 is connected to the mounting plate 41 and can move and adjust vertically on the mounting plate 41. This allows for the use of parts with varying dimensions. The sensor 43 is connected to the slide cylinder 42. The slide cylinder 42 drives the sensor 43 to move closer to or away from the rotary clamping electric cylinder 32. The sensor 43 is used to detect the position of holes on the part. The rotary clamping electric cylinder 32 drives the part to rotate so that the holes face the sensor 43 for detection, and the rotary clamping electric cylinder 32 also drives the part to stop rotating.

[0032] The mounting bracket 31 has a bolt threaded on its top. The mounting plate 41 has an elongated hole 411 that extends in the front-to-back direction. The bolt is inserted into the elongated hole 411 and can press and limit the mounting plate 41 onto the mounting bracket 31. The elongated hole 411 also allows the front-to-back direction of the mounting plate 41 to be adjusted, thus accommodating parts with different outer diameters.

[0033] Reference Figure 3 and Figure 4 A slide rail 44 is bolted to the side of the mounting plate 41 away from the base plate 1. A slider 45 is slidably connected to the slide rail 44 in the vertical direction. A linkage plate 46 is bolted to the slider 45, and the linkage plate 46 slides synchronously with the slider 45. The cylinder body of the slide cylinder 42 is bolted to the linkage plate 46, and the slide of the slide cylinder 42 can move closer to or away from the rotary clamping electric cylinder 32 relative to the cylinder body. A fixing member is bolted to the side of the slide of the slide cylinder 42 closest to the rotary clamping electric cylinder 32, and a sensor 43 is fixedly mounted on the fixing member to detect holes.

[0034] A limiting bolt is threaded onto the mounting plate 41, which can lock or unlock the linkage plate 46. Specifically, the linkage plate 46 has an oblong hole 461 extending vertically. The limiting bolt is inserted into the oblong hole 461 and threadedly connected to the mounting plate 41. The limiting bolt is suitable for pressing and limiting the linkage plate 46 onto the mounting plate 41, thereby limiting the vertical movement of the slider 45, the linkage plate 46, and the slide cylinder 42. This is suitable for parts with different height dimensions.

[0035] The implementation principle of the part flipping detection device in this application embodiment is as follows: the flipping clamping drive 2 can flip the part by 180 degrees, so that the large end of the part is facing down. When flipping the part, the rotation drive assembly 3 moves down to avoid interference and collision. After the part is flipped by the flipping clamping drive 2, the lifting drive 11 drives the rotation drive assembly 3 to move up, so that the three-jaw gripper 36 is inserted into the part. The three-jaw gripper 36 opens its rear side to clamp the part. Then the lifting drive 11 drives the rotation drive assembly 3 to move the part down, and the slide cylinder 42 drives the sensor 43 to move towards the rotary clamping electric cylinder 32 to detect the position of the hole. If the sensor 43 does not detect the hole, the control system will control the rotary clamping electric cylinder 32 to drive the part to rotate until the hole is detected by the sensor 43. Then the rotary clamping electric cylinder 32 stops driving the part to rotate. At the same time, the flipping clamping drive 2 flips the next part.
