Description

Technical Field

[0001] This utility model relates to the field of sensor manufacturing equipment, and in particular to an automated mechanism for precisely cutting sensor strips. Background Technology

[0002] In the sensor manufacturing process, traditional methods of separating sensor strips rely on manual prying. However, this manual operation has many insurmountable problems. Manual prying inevitably generates a large number of burrs at the joints of the sensor strips. In subsequent automated assembly processes, these burrs severely interfere with the precise alignment and installation of components, leading to a sharp increase in assembly defect rates. Moreover, the presence of burrs may also affect sensor performance, such as disrupting signal transmission stability and reducing sensing accuracy, or even causing the sensor to malfunction completely.

[0003] Chinese patent application CN220994660U discloses an automated sensor-based cutting device, which is equipped with only one set of molds and cutting equipment. When there is a need to change the product model being cut, the machine must be stopped for equipment parameter adjustments and mold replacement. This process is time-consuming and labor-intensive, severely restricting production efficiency. Moreover, the equipment lacks subsequent inspection devices, making it impossible to effectively identify whether the finished product is defective, which is detrimental to product quality control and production process optimization.

[0004] Therefore, overcoming the above-mentioned shortcomings has become an important issue that urgently needs to be addressed by those skilled in the art. Utility Model Content

At least one second gripper 63 is mounted on the first movable seat 61 to clamp the sensor strip onto the mold 21.

[0015] Preferably, a vertical scraper 64 is provided next to the second gripper 63, and the scraper 64 is connected to a seventh drive assembly 65 that moves it back and forth; a cuboid waste bin 66 is provided below the second gripper 63, and the scraper 64 is used to push the cut waste material to fall into the waste bin 66.

[0016] Preferably, a second movable seat 71 and an eighth drive assembly 72 for driving the second movable seat 71 to move laterally are provided below the fixture 2; the fixture 2 and the first drive assembly 72 are fixedly installed on the second movable seat 71; the eighth drive assembly 72 changes the cutting position of the cutting device 3 on the sensor strip by adjusting the lateral position of the fixture 2.

[0019] Compared with existing technologies, the beneficial effects of this utility model are:

[0020] 1. The automatic sensor strip cutting mechanism utilizes the precise collaboration of multiple drive components to achieve accurate control of the cutting action across multiple dimensions. It can flexibly and precisely adjust key parameters such as cutting position, angle, and depth. Compared to traditional manual tearing methods, its advantages lie not only in effectively suppressing burr formation but also in the refined management of the entire cutting process. This precise cutting capability ensures the integrity and consistency of the sensor strip during separation, avoiding problems such as edge damage and deformation caused by improper cutting, thus comprehensively protecting the physical structural integrity of the sensor. From a performance perspective, precise cutting helps maintain the stability of the sensor's internal electrical performance, ensuring the accuracy and reliability of signal transmission, and avoiding adverse phenomena such as signal interference and attenuation caused by cutting defects. This allows the sensor to work more stably and efficiently in practical applications, significantly improving the overall quality and performance of the product.

[0021] 2. Equipped with a unique quick mold change device, unlike some existing automated cutting equipment that only has a single mold and cutting device. When different models of sensors need to be produced, operators can complete the mold switching operation in a very short time, without the need for long downtime to wait for mold replacement and equipment debugging. This allows the machine to quickly adapt to diverse production needs, flexibly switch between production tasks of different product models, greatly improve the overall production efficiency of the production line and the ability to respond to market changes, and effectively reduce production downtime and cost waste caused by product switching.

[0022] 3. It integrates a high-precision and comprehensive testing device, overcoming the shortcomings of some existing equipment that lack testing functions. It can perform multi-dimensional and precise testing on individual sensors after cutting, including but not limited to accurate measurement of external dimensions and detailed evaluation of surface flatness. By promptly identifying and screening out unqualified products, product quality is effectively guaranteed. Attached Figure Description

[0030] The following examples will further illustrate the features of this utility model and other related features in detail, so as to enable those skilled in the art to understand them.

[0031] like Figures 1-7 As shown, to achieve the above objectives, this novel experimental design employs the following technical solutions:

[0032] I. Selection of Dies and Stamping Components and Fixture Positioning

[0033] Before production begins, the control system sends a command to the first drive component 22 of the fixture 2. The first drive component 22 drives the fixture 2 to rotate precisely according to the command, rotating the working side of the mold 21 that is adapted to the sensor strip of this model to the operating position, ensuring that the positioning of the mold 21 is accurate. Its positioning accuracy error can be controlled within a very small range, such as within ±0.05 mm, providing an accurate basis for the subsequent placement of the sensor strip.

[0034] Simultaneously, the control system determines relevant parameters of the cutting device 3 based on the selected mold 21 and sensor strip model, such as the movement trajectory of the punch head 35, cutting force, and speed. The second drive assembly 32 and the third drive assembly 34 of the cutting device 3 are then initialized and adjusted accordingly, moving the punch head 35 to a safe starting position away from the fixture 2, such as moving it laterally to more than 50 mm from one side of the fixture 2, or vertically raising it to more than 100 mm from the surface of the mold 21, thus providing sufficient space for the sensor strip loading and avoiding interference.

[0035] In the positioning stage of fixture 2, the ninth drive component 27 drives the positioning pin 28 to insert into the positioning hole 26 from the inside out, so as to achieve precise positioning of fixture 2. The positioning accuracy can reach ±0.02 mm. This precise positioning provides a basic guarantee for the subsequent precise cutting of sensor strips.

[0036] II. Sensor Strip Feeding and Positioning

[0037] After receiving the loading command from the control system, the material transfer device 6 uses the sixth drive assembly 62 to drive the first movable seat 61 to move longitudinally, causing the second gripper 63 mounted on the first movable seat 61 to reach the sensor strip placement position. The second gripper 63 closes and grasps the sensor strip within the cavity 20. Then, the sixth drive assembly 62 drives the first movable seat 61 again, transferring it to the corresponding position above the fixture 2. When the sensor strip reaches the fixture 2, the positioning protrusion 24 and positioning groove 25 of the mold 21 initially align with the outline of the sensor strip for positioning. The vacuum suction hole 23 generates suction force, firmly adhering the sensor strip to the surface of the mold 21. If further fine-tuning of the sensor strip position is required, the eighth drive assembly 72 below the fixture 2 can drive the fixture 2 to make minor adjustments in the lateral direction to ensure the sensor strip is in the optimal cutting position.

[0038] III. Sensor Strip Cutting Process

[0039] Once the sensor strip is precisely positioned on fixture 2, the cutting device 3 begins the cutting operation. The second drive assembly 32 first drives the mounting block 31 to move laterally, moving the punch head 35 of the stamping assembly 33 above the first cutting position of the sensor strip. This position is precisely calculated by the control system based on the sensor strip model and cutting requirements. Then, the third drive assembly 34 drives the stamping assembly 33 to move downwards vertically. The punch head 35 passes through the punching hole 29 on the mold 21, matching its size, and applies precise pressure to the sensor strip, completing the cutting of a specific area. During the cutting process, the control system precisely controls the parameters of the third drive assembly 34 and the second drive assembly 32 based on parameters such as the sensor strip material and thickness, ensuring that the descent speed, pressure, and cutting position of the punch head 35 are accurate, thereby guaranteeing cutting quality. For example, for a sensor strip with a thickness of 0.2 mm, the descent speed of the punch head 35 can be set to 0.1 m / s, and the pressure to 200 Newtons. If the sensor strip requires continuous cutting of multiple parts or multiple sensors, after the first cut, the eighth drive assembly 72 drives the fixture 2 and the mold 21 fixed on the fixture 2 to move in the longitudinal direction by a precise distance, such as 10 mm, according to the preset spacing parameters between adjacent cutting positions of the sensor strip, so that the next cutting position is accurately aligned with the punch head 35. Subsequently, the second drive assembly 32 finely adjusts the lateral position of the punch head 35 again (if necessary), and the third drive assembly 34 drives the punch head 35 to cut the next position. This cycle is repeated until all parts of the sensor strip that need to be cut are completed.

[0040] IV. Post-cutting processing

[0041] After the cutting is completed, the gripping device 4 starts to work. The second gripper 63 moves upward under the drive of the sixth drive component 62 to grab the waste material. Then, the second gripper 63 moves inward to above the waste bin 66. Then, the seventh drive component 65 drives the scraper 64 to move outward again. During the movement, the scraper 64 scrapes the waste material on the second gripper 63 into the waste bin 66, thereby realizing the automatic cleaning of waste material.

[0042] The vision inspection device 5 monitors the entire process in real time. The first vision inspection component 51 and the second vision inspection component 52 inspect the sensor strip and its parameters, such as thickness, width, and surface flatness. If any abnormality is detected, such as thickness exceeding the set tolerance range, obvious scratches on the surface, or dimensions not meeting requirements, the vision inspection device 5 will immediately send an alarm signal to the control system and record the relevant inspection data. Based on this information, the control system controls the gripping device 4 to move the defective sensor to the recycling area or recycling device. If the inspection is successful, the gripping device 4 moves the sensor to the next production process according to a preset path.

[0043] Through the close cooperation and coordinated operation of the above-mentioned devices, the automatic sensor strip cutting mechanism of the present invention can efficiently and accurately complete the cutting and related processing operations of sensor strips, meet the automation requirements of the sensor production process, improve production efficiency and product quality, and flexibly adapt to the production tasks of various types of sensor strips.
