Technical Field
[0001] This utility model relates to the field of ultrasonic transducer manufacturing technology, and in particular to a guide needle feeding module of a guide needle feeding mechanism. Background Technology
[0002] As is well known, ultrasonic sensors typically consist of a housing, a transducer, a mask, and a support. The transducer, or piezoelectric ceramic plate, converts electrical energy into mechanical energy and is an important component of ultrasonic sensors.
[0003] Currently, most of the guide pins required for transducer welding on the market are obtained by cutting guide pin coils to the required size. Because the required sizes of the guide pins are not standardized, they are often mixed up haphazardly during storage, making the extraction process complex. Currently, the guide pins are generally extracted manually and then manually welded onto the transducer by operators. Manual extraction of guide pins has the following disadvantages: First, the guide pins are left in a free state in the container, piling up on each other. During the manual handling process, some guide pins become bent or twisted, requiring manual correction, and in severe cases, they may even become unusable. Second, because the welding is done manually by hand, relying on the operator's visual positioning, the welding point error is relatively large, resulting in a high defect rate.
[0004] Therefore, it is necessary to provide a guide pin feeding module that can automate the feeding of guide pins, a guide pin feeding mechanism having the guide pin feeding module, and a transducer guide pin welding machine having the guide pin feeding mechanism. Utility Model Content

During the process of the guide pin passing through the straightening gap, the straightening component automatically straightens the shape of the guide pin, preventing it from bending or twisting. After the guide pin moves to the cutting component, the cutting component cuts the guide pin, thereby providing a guide pin of the required size. Therefore, the guide pin feeding module of this invention can achieve automated feeding of guide pins and ensure that the provided guide pins have a straight structure, greatly reducing manual labor and effectively improving production efficiency.

During the process of the guide needles passing through the straightening gap, the straightening component automatically straightens the shape of the guide needles to prevent them from bending or twisting. After the guide needles move to the cutting component, the cutting component cuts the guide needles so that the cut guide needles can fall into the vibrating plate.

By rotating the gap adjusting member 213, the first straightening frame 211 is moved relative to the second straightening frame 212, thereby adjusting the size of the straightening gap. The gap adjusting member 213 can be an existing adjusting bolt knob, but is not limited to this.
[0041] Please see Figure 1 and Figure 2 In one embodiment, two straightening components 2 are disposed between the guide pin winding positioning component 1 and the feeding component 3, and the straightening directions of the two straightening components 2 for the guide pin are perpendicular to each other. Specifically, one straightening component 2 is arranged in the horizontal direction, while the other straightening component 2 is arranged in the vertical direction. The two straightening components 2 are used to straighten the guide pin passing through their straightening gap in the horizontal and vertical directions respectively, thereby ensuring that the guide pin has a straight structure and avoiding bending or twisting of the guide pin.
[0042] Please see Figure 1 and Figure 2In one embodiment, the feeding assembly 3 includes a feeding bracket 31, a feeding rotation drive module 32, and feeding rollers 33. The feeding bracket 31 is disposed on the feeding bracket 101, and two feeding rollers 33 are rotatably connected to the feeding bracket 31 at intervals. There is a feeding gap between the two feeding rollers 33 for feeding guide needles. The feeding rotation drive module 32 is connected to one of the feeding rollers 33. The feeding roller 33 is driven to rotate by the feeding rotation drive module 32 to feed the guide needles passing through the feeding gap. Specifically, the feeding bracket 31 includes a first feeding frame 311 and a second feeding frame 312, wherein one feeding roller 33 is rotatably connected to the first feeding frame 311 and the other feeding roller 33 is rotatably connected to the second feeding frame 312. The first feeding frame 311 and the second feeding frame 312 are adjustablely positioned on the feeding bracket 31. By adjusting the position between the first feeding frame 311 and the second feeding frame 312, the size of the conveying gap can be adjusted.
[0043] Please see Figure 1 and Figure 2 In one embodiment, the cutting assembly 4 includes a cutting frame 41, a cutting drive module 42, and a cutting blade 43. The cutting frame 41 is disposed on the feeding bracket 101 and has a positioning hole 411 for the guide needle to pass through. The cutting drive module 42 is disposed on the cutting frame 41 and is connected to the cutting blade 43. The cutting drive module 42 is used to drive the cutting blade 43 to move, so that the cutting blade 43 cuts the guide needle passing through the positioning hole 411.
[0044] Specifically, the cutting drive module 42 includes a cutting drive motor 421, a cutting drive cam 422, and a cutting spring 423. The cutting drive motor 421 is mounted on the cutting frame 41, and its output end is connected to the cutting drive cam 422. The cutting blade 43 is slidably mounted on the cutting frame 41, and the cutting drive cam 422 abuts against the cutting blade 43. The cutting spring 423 abuts against the cutting blade 43 and the cutting frame 41 along the sliding direction of the cutting blade 43. The cutting spring 423 applies an elastic force to the cutting blade 43 to drive it to slide away from the guide needle. The cutting drive motor 421 drives the cutting drive cam 422 to rotate, causing the cutting drive cam 422 to push the cutting blade 43 to move and compress the cutting spring 423. When the protruding portion of the cutting drive cam 422 abuts against the cutting blade 43, the cutting blade 43 moves downward and cuts the guide pin passing through the positioning hole 411, while simultaneously compressing the cutting spring 423. When the protruding portion of the cutting drive cam 422 disengages from the cutting blade 43, the cutting blade 43 moves upward and away from the guide pin under the elastic force of the cutting spring 423. The length of the guide pin can be changed by adjusting the speed of the cutting drive motor 421. More specifically, the cutting frame 41 is provided with a cutting slide 412, the cutting blade 43 slides on the cutting slide 412, and an auxiliary roller 431 is rotatably connected to the cutting blade 43, with the cutting drive cam 422 abutting against the auxiliary roller 431.
[0045] Among them, the guide needle material is a flexible material. In its original state, it is a guide needle roll. It needs to be straightened by the straightening component 2 and then flows into the feeding component 3. The feeding component 3 can control the roller to ensure that the length of the guide needle is consistent each time. It works with the cutting component 4 to cut and controls the cycle time. The time for each cut by the cutting component 4 is consistent with the time for the feeding component 3 to determine the length of the guide needle.
[0046] Please see Figures 1 to 5The present invention also provides a guide needle feeding mechanism 200, which includes a vibrating plate 5, a direct vibration conveying assembly 6, a guide needle baffle 7, a material distribution assembly 8, and a guide needle feeding module 100 of any of the above embodiments.

[0047] In this invention, the cut guide pins from the cutting component 4 flow into the vibrating plate 5, and then are sequentially discharged through the straight vibration conveying component 6. When a guide pin reaches the end of the straight vibration conveying channel, the guide pin baffle 7 blocks the guide pin located at the end of the straight vibration conveying channel to ensure consistent picking position each time. Then, the guide pin gripper 84 is driven by the material distribution component 8's material distribution gripper drive module 83 to grip the guide pin located at the end of the straight vibration conveying channel. Subsequently, the material distribution flipping drive module 82 drives the material distribution gripper drive module 83 and the guide pin gripper 84 to flip together, with a flipping angle of up to 90 degrees, thereby distributing the guide pins and realizing the feeding of guide pins.

[0051] Please see Figure 7 and Figure 8In one embodiment, the transducer hopper 304a includes a second turntable 304a1, a second turntable drive module 304a2, a material clamp 304a3, and a lifting module 304a4. The second turntable 304a1 is rotatably connected to the mounting frame 301. The second turntable drive module 304a2 is disposed on the mounting frame 301 and connected to the second turntable 304a1. The second turntable drive module 304a2 is used to drive the second turntable 304a1 to rotate. A material clamp 304a3 is disposed on the second turntable 304a1 along the circumferential direction. The material clamp 304a3 has a receiving cavity arranged vertically for accommodating the transducer. The second turntable 304a1 is disposed at the output end of the second turntable drive module 304a2. The second turntable drive module 304a2 drives the second turntable 304a1 to rotate, causing the material clamps 304a3 to rotate sequentially above the lifting module 304a4. Specifically, the lifting module 304a4 is disposed on the mounting frame 301. The second turntable drive module 304a2 drives the second turntable 304a1 to rotate, causing one of the material clamps 304a3 to rotate above the lifting module 304a4, thereby allowing the lifting module 304a4 to penetrate the receiving cavity and lift the transducer within the receiving cavity. The material clamp 304a3 has a accommodating cavity that can hold several transducers stacked vertically. Specifically, the lifting module 304a4 includes a lifting motor 304a41 and a push rod 304a42. The lifting motor 304a41 is connected to the push rod 304a42, and the lifting motor 304a41 drives the push rod 304a42 to move up and down, allowing the push rod 304a42 to enter or exit the accommodating cavity. By driving the push rod 304a42 upward through the lifting motor 304a41, the push rod 304a42 enters the accommodating cavity of the material clamp 304a3 and pushes the transducers. Each time the push rod 304a42 lifts a transducer by one position, the transducer handling robot 304d removes one transducer.
[0052] In one embodiment, the lifting module 304a4 further includes a position sensor 304a43, which is used to detect the lifting position of the lifting module 304a4. When the lifting module 304a4 is raised to the limit position set by the position sensor 304a43, all the transducers in the material clamp 304a3 have been picked up. The lifting motor 304a41 of the lifting module 304a4 drives the push rod 304a42 to descend, so that the push rod 304a42 exits the receiving cavity. The second turntable drive module 304a2 then drives the second turntable 304a1 to rotate, so that the next new material clamp 304a3 rotates to the top of the lifting module 304a4, so that the lifting component can be inserted into the receiving cavity of the material clamp 304a3 again and lift the transducers to cooperate with the transducer handling robot 304d to pick up the material. This cycle continues.

[0063] Please see Figure 3 and Figure 16 In one embodiment, the transducer guide pin welding machine 300 of this utility model further includes a guide pin welding detection module 308, which is disposed on the mounting frame 301 and used to detect the welding effect between the guide pin and the transducer.
[0064] Combination Figures 1 to 16 The specific working principle of the transducer guide pin welding machine 300 of this utility model is as follows:
[0065] The feeding assembly 3 feeds the guide pins on the guide pin roll positioning assembly 1, allowing the guide pins to pass through the straightening gap of the straightening assembly 2 and move to the cutting assembly 4. During the process of the guide pins passing through the straightening gap, the straightening assembly 2 automatically straightens the shape of the guide pins to prevent them from bending or twisting. After the guide pins move to the cutting assembly 4, the cutting assembly 4 cuts the guide pins so that the cut guide pins can fall into the vibrating plate 5. The straight vibration conveying assembly 6 uses the straight vibration material channel to straight vibration convey the guide pins. The guide pin baffle 7 can block the guide pins located at the end of the straight vibration material channel and ensure that the position of each part is consistent. Then, the material distribution assembly 8 clamps the guide pins located at the end of the straight vibration material channel and flips the guide pins, thereby distributing the guide pins and realizing the automated feeding of guide pins.
[0066] The second turntable drive module 304a2 of the transducer feeder mechanism 304 drives the second turntable 304a1 to rotate, so that one of the material clamps 304a3 rotates to the top of the lifting module 304a4. The lifting module 304a4 enters the receiving cavity and lifts the transducer in the receiving cavity. The transducer transport robot 304d simultaneously transports the transducer lifted out of the material clamp 304a3 in the transducer feeder 304a to the transducer flipping mechanism 304b and transports the transducer on the transducer flipping mechanism 304b to the transducer rotating mechanism 304c. In the transducer flipping mechanism 304b, the transducer flipping gripper 304b3 grips the transducer, and the first CCD detection module 304e below performs appearance inspection on the transducer to determine whether it is qualified and whether the incoming material position is correct. If the incoming material position is incorrect, the transducer flipping mechanism 304b flips the transducer. At the position of the transducer rotation mechanism 304c, if the first CCD detection module 304e determines that the transducer is a qualified product, the transducer positioning fixture 304c1 adsorbs and positions the transducer transporting robot 304d, and the second transducer gripper drive module 304c3 drives the rotating gripper to close, thereby positioning the transducer in the transducer positioning fixture 304c1. The transducer rotation drive module 304c2 drives the transducer positioning fixture 304c1 to rotate, and the second CCD detection module 304f performs alignment detection on the transducer on the transducer rotation mechanism 304c to ensure the accuracy of the welding position 302b. If the first CCD detection module 304e determines that the transducer is a defective product, the transducer transporting robot 304d transports the transducer located on the transducer flipping mechanism 304b to the defective product box 304c5. After the second CCD detection module 304f detects the transducer, the transducer loading module 305 transports the transducer on the transducer positioning fixture 304c1 of the transducer rotating mechanism 304c to the transducer fixing fixture 302d of the loading position 302a of the turntable. The first turntable driving module 303 drives the first turntable 302 to rotate, so that the transducer rotates to the welding position 302b. The guide pin transport module 306 transports the guide pin on the material distribution component 8 to the welding position 302b, so that the welding robot 307 automatically welds the guide pin and the transducer together at the welding position 302b.
[0067] In summary, the transducer guide pin welding machine 300 of this utility model can automatically feed the guide pins and ensure that the provided guide pins have a straight structure. At the same time, it can also automatically weld the guide pins to the transducer, which fully guarantees the welding effect between the guide pins and the transducer, greatly reduces manual labor, and effectively improves production efficiency.
