Description

Technical Field

[0001] This utility model relates to the field of rebar cutting equipment technology, and in particular to a pressure sensor rebar cutting and forming equipment. Background Technology

[0002] In the manufacturing process of pressure sensors, lead cutting and forming is a crucial core step. Its main function is to precisely cut the metal ribs that connect the sensor chip to the external pins, while ensuring the structural integrity, electrical insulation, and performance stability of the sensor after forming. This directly affects the yield rate and reliability of the final product. With the continuous growth in demand for pressure sensors in fields such as industrial automation, automotive electronics, and medical equipment, the market has placed higher demands on the miniaturization, high precision, high stability, and mass production efficiency of sensors. Traditional lead cutting and forming technology has gradually revealed many unsolvable technical pain points and can no longer meet the current industry development needs.

[0003] Chinese patent CN221041052U discloses a semiconductor bead cutting and forming apparatus, relating to the field of semiconductor processing. The apparatus includes a chassis containing a magazine, a feeding track, a clamping mechanism, a shifting mechanism, and a bead cutting and bending mechanism. The magazine and shifting mechanism are sequentially arranged on one side of the feeding track. The magazine is used to stack several frames, and a top-loading cylinder is located at the bottom of the magazine to push the frames upwards. The clamping mechanism is used to clamp the frames in the magazine onto the feeding track. The shifting mechanism is used to move the frames within the feeding track. The bead cutting and bending mechanism is used to perform bead cutting and bending actions on the frames within the feeding track. This patent improves the ease of operation and efficiency of semiconductor cutting to some extent through the cooperation of automated feeding and cutting mechanisms, but it still fails to solve the core technical pain points mentioned above: its cutting and bending mechanism relies on mechanical tools or fixed-parameter lasers, lacks the ability to precisely adjust the spacing of pressure sensors, and cannot adapt to the processing requirements of miniaturized, high-precision sensors; it does not have an effective distance monitoring and anti-interference structure, making it difficult to cope with thermal deformation and electromagnetic interference in laser processing, and unable to guarantee the stability of cutting quality.

[0004] Therefore, there is an urgent need for a cutting and forming equipment that can achieve non-contact, accurate distance monitoring, dynamically adjust the processing spacing, has anti-interference capabilities, and is compatible with the batch processing of miniaturized pressure sensors, in order to meet the industry's production needs for high-quality pressure sensors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A pressure sensor rebar cutting and forming device includes a base plate, an electric telescopic rod is provided on one side of the base plate, a support platform is installed at the end of the electric telescopic rod away from the base plate, and a wire is provided on the support platform; The laser unit includes a fixing plate and a laser device.

One end of the laser channel is provided with an emission source, and the other end is provided with a laser head. A sensor is arranged around the outer surface of the laser head. The laser head and the sensor are integrally formed, and a mounting base is provided between the laser head and the main body. A contact pin is provided on one side of the mounting base. One side of the contact pin is electrically connected to the sensor through the mounting base, and the other end is provided with a transmitter. The outer peripheral surface of the mounting base is covered with an external insulating component, which extends to the outer periphery of the sensor.

[0007] Preferably, the sensor has an internal insulating component on the side near the emission source.

[0009] Preferably, an intermediate component is installed between the mounting base and the sensor, and the intermediate component is made of conductive material for electrical conduction between the mounting base and the sensor.

[0010] Preferably, the laser channel has a laser beam shaping optical element disposed between the emission source and the laser head. The laser beam shaping optical element is coaxially disposed with the laser channel and is used to adjust the spot shape and energy distribution of the laser beam.

[0011] Preferably, the inner insulating component is fixedly connected to the outer insulating component.

[0012] Preferably, the laser channel is made of an insulating material.

The suction component is installed on the baffle on the opposite side of the air nozzle.

[0015] Preferably, a rotary drive device is provided at the bottom of the receiving part.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This invention connects a contact pin to an external capacitance detection circuit, introducing the positive terminal of the circuit. A sensor is then inserted via a mounting base, forming the sensor as the positive electrode. A wire in the receiving port connects to the external capacitance detection circuit, introducing the negative terminal, forming the sensor as the negative electrode. Non-contact distance monitoring is achieved by utilizing the inverse relationship between the capacitance and distance between the two electrodes, forming a closed-loop adjustment system of capacitance signal, transmitter, control console, and electric telescopic rod. When the distance is detected to be too close, the transmitter sends a capacitance change signal to the control console, which then drives the electric telescopic rod. The retractable rod increases the spacing; when the spacing is too far, the control console extends the electric telescopic rod to reduce the spacing, thereby dynamically maintaining a suitable processing distance between the laser head and the pressure sensor to be processed, significantly improving the positional accuracy of the rib cutting process; at the same time, the outer insulation component's wrapping design of the mounting base effectively blocks external electromagnetic interference, ensuring the stability of capacitive signal transmission; the inclined electrical connection structure between the contact pin and the mounting base reduces impedance loss in the signal transmission path, and together with the precise positioning of the workpiece by the receiving part, further ensures the real-time performance of distance monitoring and adjustment response speed, ultimately achieving consistency and improved pass rate of pressure sensor rib cutting.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A pressure sensor rebar cutting and forming device includes a base plate 1, an electric telescopic rod 2 is provided on one side of the base plate 1, a support platform 3 is installed on the end of the electric telescopic rod 2 away from the base plate 1, and a wire 28 is provided on the support platform 3; The laser unit includes a fixing plate 10 and a laser device 8. The laser device 8 is mounted on the side of the fixing plate 10 near the support platform 3. The laser device 8 includes a main body 11. The main body 11 has an axially penetrating laser channel 12. One end of the laser channel 12 is provided with an emission source 13, and the other end is provided with a laser head 14. A sensor 15 is arranged around the outer surface of the laser head 14. The laser head 14 and the sensor 15 are integrally formed. A mounting base 16 is provided between the laser head 14 and the main body 11. A contact pin 17 is provided on one side of the mounting base 16. One side of the contact pin 17 is electrically connected to the sensor 15 through the mounting base 16, and the other end is provided with a transmitter 18. The outer peripheral surface of the mounting base 16 is covered with an outer insulating part 19, which extends to the outer periphery of the sensor 15. The sensor 15 is a capacitive distance sensor. The contact pin 17 is connected to an external capacitance detection circuit, and the positive terminal of the capacitance detection circuit is introduced into it. The sensor 15 is then transferred through the mounting base 16 to form a positive electrode plate. The wire 28 in the receiving port 7 is connected to the external capacitance detection circuit and the negative terminal of the capacitance detection circuit is introduced into it to form a negative electrode plate. Non-contact distance monitoring is achieved by utilizing the inverse ratio between the capacitance value and the distance between the two electrodes. The transmitter 18, the control console 9, and the electric telescopic rod 2 are electrically connected.

[0021] In use, this device utilizes the inverse relationship between capacitance and distance between the two plates. The conductive sensor 15 is configured as the positive plate for capacitance measurement, and the pressure sensor 15 is used as the negative plate. This enables non-contact distance monitoring, forming a closed-loop control system encompassing the capacitance signal, transmitter 18, control console 9, and electric telescopic rod 2. When the distance is detected to be too close, the transmitter 18 transmits the capacitance change signal to the control console 9, which then drives the electric telescopic rod 2 to retract, increasing the distance. When the distance is too far, the control console 9 controls the electric telescopic rod 2 to extend, decreasing the distance and thus dynamically maintaining the laser head 14. The appropriate processing distance between the pressure sensor 15 and the substrate significantly improves the positional accuracy of the rib cutting process. Simultaneously, the outer insulating part 19's wrapping design around the mounting base 16 effectively blocks external electromagnetic interference, ensuring the stability of the capacitive signal transmission. The inclined electrical connection structure between the contact pin 17 and the mounting base 16 reduces impedance loss in the signal transmission path. Combined with the precise positioning of the workpiece by the receiving part 6, this further ensures the real-time performance of distance monitoring and the speed of adjustment response, ultimately achieving consistency and improved pass rate in the cutting of the pressure sensor ribs. It should be noted that the sensor to be processed is made of a material with good electrical conductivity. In addition, the outer insulation component 19 is made of plastic, specifically polyetheretherketone, polytetrafluoroethylene, nylon, and polyphenylene sulfide. The plastic is existing technology and will not be described in detail here.

[0022] In the example of this application, the sensor 15 is provided with an inner insulating element 20 on the side near the emission source 13.

[0023] As a preferred example of this utility model, the inner insulating component 20 disposed on the side of the sensor 15 near the emission source 13 can block stray current between the conductive components inside the laser body 11 and the sensor 15, avoid the formation of parasitic capacitance that interferes with measurement accuracy, and at the same time reduce the conduction of heat from the laser channel 12 to the sensor 15, ensuring the working stability of the sensor 15. The inner insulating component 20 is made of brass, aluminum, copper or stainless steel. The brass, aluminum, copper or stainless steel are existing technologies and will not be described in detail here.

[0024] In the example of this application, an electrical insulation structure 21 is provided between the inner insulating member 20 and the sensor 15, and the electrical insulation structure 21 is an air gap.

[0025] As a preferred example of this utility model, the air gap between the inner insulating component 20 and the sensor 15 serves as an electrical insulation structure 21. This structure not only ensures electrical isolation between the two through the high insulation properties of the air medium, but also further blocks heat transfer by utilizing the low thermal conductivity of the gas. At the same time, it avoids the assembly stress caused by the contact of solid insulating materials from affecting the positional accuracy of the sensor 15, thereby improving the accuracy of capacitance measurement.

[0026] In the example of this application, an intermediate component 22 is installed between the mounting base 16 and the sensor 15, and the intermediate component 22 is made of conductive material for electrical conduction between the mounting base 16 and the sensor 15.

[0027] As a preferred example of this utility model, the intermediate component 22 made of conductive material can optimize the reliability of the electrical connection between the mounting base 16 and the sensor 15, reduce the attenuation of the capacitive signal transmission due to the contact resistance, and at the same time compensate for the assembly tolerance of the mounting base 16 and the sensor 15 through the structural adaptability of the intermediate component 22, ensuring the dual stability of both in mechanical fixation and electrical conduction.

[0028] In the example of this application, the laser channel 12 is provided with a laser beam shaping optical element 23 between the emission source 13 and the laser head 14. The laser beam shaping optical element 23 is coaxially arranged with the laser channel 12 and is used to adjust the spot shape and energy distribution of the laser beam.

[0029] As a preferred example of this utility model, the laser beam shaping optical element 23, which is coaxially arranged in the laser channel 12, can precisely adjust the spot shape and energy distribution of the laser beam, so that the laser energy is concentrated in the rib area of ​​the pressure sensor 15, reducing the thermal impact on the surrounding sensitive elements and improving the smoothness of the rib cutting edge and the consistency of processing quality.

[0030] In the example of this application, the inner insulating member 20 is fixedly connected to the outer insulating member 19.

[0031] As a preferred example of this utility model, the fixed connection between the inner insulating component 20 and the outer insulating component 19 can form an integrated insulating shielding structure, which enhances the electromagnetic protection capability of the sensor 15 component. At the same time, the rigid connection between the two restricts the relative displacement of the internal components of the laser body 11, ensuring the coaxiality of the laser channel 12 and the sensor 15, and maintaining long-term processing accuracy. The inner insulating component and the outer insulating component 19 are fixedly connected by press fitting, bonding or casting.

[0032] In the example of this application, the laser channel 12 is made of an insulating material.

[0033] As a preferred example of this utility model, the laser channel 12 made of insulating material can prevent the induced current generated during laser transmission from being conducted to other components, eliminate electromagnetic interference sources, reduce the absorption loss of laser energy by the inner wall of the channel, improve laser utilization efficiency, and indirectly reduce the impact of thermal deformation during processing. The insulating material can be made of ceramic, which is existing technology and will not be described in detail here.

[0034] In the example of this application, the support platform 3 is provided with a receiving part 6, the upper surface of the receiving part 6 is provided with a receiving opening 7, the receiving opening 7 is provided with a wire 28, and the receiving part 6 is provided with baffles 5 around it. The baffles 5 enclose the cutting space 4. A laser device 8 is provided above the support platform 3, and a control console 9 is provided on one side of the support platform 3. A waste material collection device 24 is provided on the baffles 5. The waste material collection device 24 includes an air nozzle 25 and a suction member 26. One end of the air nozzle 25 is connected through the baffle 5, and the other end is aligned with the receiving part 6. The suction member 26 is installed on the baffle 5 on the side opposite to the air nozzle 25.

[0035] As a preferred example of this utility model, by setting a waste material collection device 24 on the baffle 5, the waste material generated during the cutting and forming process of the pressure sensor 15 can be effectively collected, preventing the waste material from scattering into the equipment or working area, reducing the interference of waste material on the normal operation of the equipment, and also facilitating the centralized processing of waste material in the future, thus improving the cleanliness and convenience of equipment operation. One end of the air nozzle 25 is connected through the baffle 5, and the other end is aligned with the receiving part 6. The airflow can blow the residual material in the receiving part 6 toward the suction member 26. The suction member 26 is installed on the baffle 5 on the opposite side of the air nozzle 25, which can efficiently absorb and collect the residual material carried by the airflow. This design realizes the directional and rapid collection of residual material, further optimizes the efficiency and effect of residual material collection, and ensures the cleanliness of the cutting and forming environment of the pressure sensor 15. Multiple air nozzles 25 can be provided as needed to enhance the cleaning effect. One end of the air nozzle 25 is connected to an external air storage tank, and the tail of the suction component 26 is connected to an external waste material collection bin and a suction device.

[0036] In the example of this application, a rotary drive device 27, i.e. a rotary drive motor, is provided at the bottom of the receiving part 6.

[0037] As a preferred example of this utility model, a rotary drive device 27 is provided at the bottom of the receiving part 6, which can drive the receiving part 6 to rotate, so that the pressure sensor 15 placed in the receiving part 6 can rotate with the receiving part 6 during the rib cutting and forming process, thereby allowing all parts of the pressure sensor 15 to receive the rib cutting and forming operation evenly, ensuring the consistency and uniformity of the rib cutting and forming, and improving the quality of the pressure sensor 15 rib cutting and forming.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
