Description

Technical Field

[0001] This invention specifically relates to an automatic pressure machine for sensors. Background Technology

[0002] In the production of pressure sensors, a specialized adhesive is typically used to bond an aluminum elastomer and strain gauge together. This adhesive needs to cure under high temperature and pressure. Accurate installation of the pressure sensor requires precise operation. However, current market practices involve manually placing the sensor into a pressure fixture, then placing the fixture in a pressurizing machine to apply a fixed pressure, followed by manual tightening of the fixture using nuts and clips. Therefore, this existing manufacturing method is highly dependent on manual labor, resulting in high labor intensity, low automation, and low production efficiency. Furthermore, this method is prone to inconsistent pressure applied during installation due to worker errors, leading to inconsistent zero-point outputs of the pressure sensor and inconsistent product quality. Manufacturers are required to add subsequent calibration procedures, increasing manufacturing costs.

[0003] This invention was developed precisely because of the aforementioned shortcomings. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic sensor press that reduces workload and improves efficiency.

[0005] This invention is achieved through the following technical solution:

[0006] An automatic sensor pressurizing machine is disclosed for pressurizing a sensor pressurizing fixture. The sensor pressurizing fixture includes a base plate with at least two sliding rods connected to it. A pressure plate that can slide downwards is fitted onto the sliding rods, and a locking sleeve is provided at the top of the sliding rods. The automatic sensor pressurizing machine includes a base with a workstation plate for placing the sensor pressurizing fixture, a lifting device for pushing the workstation plate up and down, a plate separating device for fixing one pressure plate when the sensor pressurizing fixture descends, thereby separating the pressure plate from the adjacent pressure plate, a feeding device for conveying material between the two separated pressure plates, and a pressurizing device for pressing the locking sleeve downwards to a preset pressure when the sensor pressurizing fixture rises.

[0007] As described above, in the automatic sensor press, the lifting device is a ball screw module. The lifting device includes a screw, a servo motor that drives the screw to rotate, and a ball slide that can move along the length of the screw when it rotates. The workstation plate is connected to the ball slide.

[0008] As described above, the automatic sensor pressurizing machine includes a plate-separating device comprising a linear module, the linear module comprising a first slide rail and a first sliding seat slidably connected to the first slide rail, the first sliding seat being connected to a separator plate that can extend into the motion path of the sensor pressurizing fixture during sliding.

[0009] As described above, the automatic sensor press has two sets of symmetrically arranged plate-separating devices on the base, and each set of plate-separating devices includes two plate-separating devices.

[0010] As described above, the sensor automatic press includes a feeding device comprising a conveyor belt for conveying materials and a clamping mechanism located on one side of the conveyor belt. The clamping mechanism includes a second sliding seat that can slide toward the sensor pressurizing fixture, and the second sliding seat is connected to a pneumatic gripper for clamping materials.

[0011] As described above, the automatic sensor press has a second slide rail on the base, and a second sliding seat is slidably connected to the second slide rail. The base also has a first driving device for pushing the second sliding seat to slide.

[0012] As described above, the automatic sensor pressurizing machine includes a swing seat, one end of which is rotatably connected to the machine base and the other end of which is connected to a counterweight assembly, such that the counterweight assembly hinders the rotation of the swing seat. The swing seat is provided with a baffle that can extend above the workstation plate to prevent the locking sleeve from moving upward.

[0013] As described above, the automatic sensor press has a third slide rail on the swing seat, a third sliding seat that can slide relative to the third slide rail is connected to the third slide rail, a baffle is connected to the third sliding seat, and the swing seat is also provided with a second driving device for pushing the third sliding seat to slide along the third slide rail.

[0014] As described above, the automatic sensor press includes a counterweight assembly comprising a counterweight block and a cable. A roller is rotatably connected to the swing seat. One end of the cable is connected to the machine base, while the other end of the cable passes over the roller from above and is connected to the counterweight block.

[0015] The automatic pressurizing machine for sensors described above includes a proximity sensor on the workstation plate for sensing the pressurization fixture. Compared with the prior art, the present invention has the following advantages:

[0016] The automatic sensor pressurizer of the present invention can automatically pressurize the sensor pressurizing fixture, automatically add materials to the sensor pressurizing fixture, and realize automated feeding and pressurization, avoiding repeated operation by operators, thereby greatly reducing the workload and improving work efficiency. Moreover, the automatic pressurization achieved by the sensor pressurizer is uniform and controllable, improving the manufacturing quality of products. Attached Figure Description

[0024] The invention will be further described below with reference to the accompanying drawings:

[0025] The orientations described in the invention specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the invention and are not a limitation on its implementation.

[0026] like Figure 1As shown, the sensor pressure fixture A includes a base plate A1, at least two slide rods A2 connected to the base plate A1, a pressure plate A3 that can slide downwards fitted on the slide rods A2, a locking sleeve A4 at the top of the slide rods A2, and a spring performance assembly A5 between the locking sleeve A4 and the base plate A1. The spring performance assembly A5 includes two spring pressure plates that are slidably connected to the slide rods A2, and a spring is connected between the two spring pressure plates. The locking sleeve A4 has a receiving groove surrounding the slide rod A2. The groove wall and the cylindrical surface of the slide rod A2 form a self-locking cavity A41. A rolling element A42 is placed inside the self-locking cavity A41. The rolling element A42 is generally a sphere, such as a metal ball or metal bead, but it can also be a regular polyhedron. The width of the self-locking cavity A41 gradually decreases from top to bottom to prevent the rolling element A42 from rolling to the bottom of the self-locking cavity A41. That is, the width distance between the bottom wall 501 of the receiving groove and the cylindrical surface of the slide rod A2 gradually decreases from top to bottom until it can... This prevents the rolling element A42 from rolling to the bottom of the self-locking cavity A41. Thus, when the locking sleeve A4 has an upward tendency to slide relative to the slide rod A2, the rolling element A42 falls downward due to its own weight, causing it to abut against the bottom wall of the receiving groove and the cylindrical surface of the slide rod A2. If the locking sleeve A4 has an upward tendency at this time, the rolling element A42 will be squeezed by the bottom wall of the receiving groove and the cylindrical surface of the slide rod A2, greatly increasing the resistance that the rolling element A42 has to overcome. Consequently, the resistance to the upward sliding of the locking sleeve A4 also increases, thus preventing the locking sleeve A4 from sliding upward.

[0027] like Figure 1 As shown, this embodiment provides an automatic sensor pressurizing machine for pressurizing a sensor pressurizing fixture A. It includes a base 1, on which a workstation plate 11 for placing the sensor pressurizing fixture A is provided; a lifting device 2 for pushing the workstation plate 11 up and down; a plate separating device 3 for fixing a pressure plate A3 when the sensor pressurizing fixture A descends, thereby separating the pressure plate A3 from the adjacent pressure plate A3; a feeding device 4 for conveying material between the two separated pressure plates A3; and a pressurizing device 5 for pressing the locking sleeve A4 downwards to a preset pressure when the sensor pressurizing fixture A rises.

[0028] As a preferred embodiment of this invention, such as Figure 1 and Figure 2As shown, the lifting device 2 adopts a ball screw module. Referencing patent number CN202223419585.X, entitled "A Ball Screw Module for Reducing Wear", the lifting device 2 in this embodiment includes a screw 21, a servo motor 22 for driving the screw 21 to rotate, and a ball slide 23 that can move along the length direction of the screw 21 when it rotates. The workstation plate 11 is connected to the ball slide 23. Then, the ball slide 23 is driven to move up and down by the forward and reverse rotation of the servo motor 22, thereby driving the workstation plate 11 to move up and down. Of course, in addition to these, the lifting device 2 can also use a telescopic motor, such as the solution provided by the patent with patent number CN202223558959.6 entitled "Hexagonal Fixed Shaft Telescopic Stepper Motor"; the driving device 43 can also use a telescopic cylinder, such as the solution provided by the patent with patent number CN200720198905.X entitled "Telescopic Cylinder"; the driving device 43 can also use a telescopic hydraulic cylinder, such as the solution provided by the patent with patent number CN201710965961.X entitled "A Telescopic Hydraulic Cylinder", as long as the output shaft of the driving device 43 is connected to the workstation plate 11.

[0029] As a preferred embodiment of this invention, such as Figure 3 and Figure 4 As shown, the machine base is provided with two symmetrically arranged partition device groups 300, each partition device group 300 including two partition devices 3. The partition device 3 includes a linear module 301. The linear module 301 can refer to the linear module in the patent solution with patent number CN201420134799.9 and name "Linear Module Protective Cover". The linear module 301 includes a first slide rail 31 and a first sliding seat 32 slidably connected to the first slide rail 31. A partition plate 33 that can extend into the movement path of the sensor pressure fixture A during sliding is connected to the first sliding seat 32. Of course, the workstation plate 11 can push the sensor pressure fixture A to move up and down. The partition device 3 can be set on one side of the movement path of the sensor pressure fixture A, so that the partition plate 33 can be controlled to extend into the movement path of the sensor pressure fixture A.

[0030] like Figure 3 As shown, the side of the partition plate 33 is provided with a groove 331, which facilitates the movement of the partition plate 33 and its insertion between the two pressure plates A3.

[0031] As a preferred embodiment of this invention, such as Figure 5 and Figure 7As shown, the feeding device 4 includes a conveyor belt 41 for conveying materials and a clamping mechanism 42 located on one side of the conveyor belt 41. The clamping mechanism 42 includes a second sliding seat 421 that can slide towards the sensor pressure fixture A. The second sliding seat 421 is connected to a pneumatic gripper 422 for clamping materials. The pneumatic gripper 422 can be a pneumatic gripper with patent number CN201920315157.1 and titled "A Pneumatic Gripper". The machine base is provided with a second slide rail 423, and the second sliding seat 421 is slidably connected to the second slide rail 423. The machine base is also provided with a first driving device 424 for pushing the second sliding seat 421 to slide. The conveyor belt 41 is used by workers or robots to place material B on it. The main material is a sensor. The pneumatic gripper 422 holds the material B. The first drive device 424 pushes the pneumatic gripper 422 to move towards the sensor pressure fixture A. The pneumatic gripper 422 moves to the space between the two pressure plates A3 separated by the plate separating device 3. The pneumatic gripper 422 releases and places the material B between the two pressure plates A3.

[0032] As a preferred embodiment of this invention, such as Figure 5 and Figure 6 As shown, the pressurizing device 5 includes a swing seat 51, one end of which is rotatably connected to the machine base, and the other end of which is connected to a counterweight assembly 52, such that the counterweight assembly 52 hinders the rotation of the swing seat 51. The swing seat 51 is provided with a baffle 53 that can extend above the workstation plate 11 to prevent the locking sleeve A4 from moving upward. The swing seat 51 is provided with a third slide rail 54, and a third sliding seat 55 that can slide relative to the third slide rail 54 is connected to the third slide rail 54. The baffle 53 is connected to the third sliding seat 55. The swing seat 51 is also provided with a second driving device 56 for pushing the third sliding seat 55 to slide along the third slide rail 54. The second drive device 56 can also be a telescopic motor, such as the solution provided in the patent with patent number CN202223558959.6 entitled "Hexagonal Fixed Shaft Telescopic Stepper Motor"; the drive device 43 can also be a telescopic cylinder, such as the solution provided in the patent with patent number CN200720198905.X entitled "Telescopic Cylinder"; the drive device 43 can also be a telescopic hydraulic cylinder, such as the solution provided in the patent with patent number CN201710965961.X entitled "A Telescopic Hydraulic Cylinder". Preferably, the baffle 53 is provided with a through hole 531 for the slide rod A2 to pass through and for blocking the locking sleeve A4 from passing through.

[0033] As a preferred embodiment of the counterweight component 52, such as Figure 5 and Figure 6As shown, the counterweight assembly 52 includes a counterweight block 521 and a cable 522. A roller 57 is rotatably connected to the swing seat 51. One end of the cable 522 is connected to the machine base, and the other end of the cable 522 passes over the roller 57 from above and is connected to the counterweight block 521. When the swing seat 51 swings upward, the swing seat 51 drives the roller 57 to move upward, which can pull the counterweight block 521 to move upward. The counterweight block 521 then pulls the swing seat 51 to swing downward, thereby pressing the locking sleeve A4 downward.

[0034] As a preferred embodiment of this invention, such as Figures 1 to 4 As shown, the workstation plate 11 is equipped with a proximity sensor 12 for sensing the pressure fixture A, so as to detect the passage of the pressure fixture A. A proximity sensor is a sensor used to detect the approach or departure of an object. The sensor can detect the presence of an object without actually contacting it. Several types of proximity sensors can be used: Infrared sensor: Uses infrared light to detect the presence or distance of an object. When an object approaches the sensor, it reflects infrared light, and the sensor detects this reflection and responds accordingly; Ultrasonic sensor: Uses the echo of ultrasonic waves to measure the distance between the object and the sensor. Ultrasonic waves are emitted and reflected back to the sensor, and the sensor determines the distance of the object by calculating the echo time; Inductive sensor: Determines the position or distance of an object by detecting its effect on the inductance. When an object approaches the sensor, it changes the inductance value in the sensor coil, thereby triggering the sensor; Photoelectric sensor: Uses the photoelectric effect to detect the presence or distance of an object. When an object enters the detection range of the sensor, it blocks or reflects light, and the sensor detects this change; Capacitive sensor: Uses the change in capacitance between the object and the sensor to detect the presence or distance of the object. When an object approaches the sensor, it changes the sensor's capacitance, thus triggering the sensor; Magnetic sensor: It uses the influence of an object on a magnetic field to detect its position or distance. When an object approaches the sensor, it changes the magnetic field strength sensed by the sensor, thus triggering the sensor.

[0035] The working principle is as follows:

[0036] 1. The sensor pressure fixture A is placed on the workstation plate 11 by a loading robot or manually to complete the loading;

[0037] 2. The lifting device 2 lifts the sensor pressure fixture A to the feeding position, that is, sends it to the position corresponding to the plate separating device 3 and the feeding device 4;

[0038] 3. At the feeding position, the partition plate 33 of the plate separating device 3 extends between two pressure plates A3. The lifting device 2 drives the station plate 11 to descend, so that the two pressure plates A3 are separated. Then the feeding device 4 puts the material B between the two pressure plates A3. Then the equipment separates the pressure fixture to the next feeding state, so that the next sensor can be put in.

[0039] 4. After material B is placed between the pressure plates A3 of the sensor pressure fixture A, the baffle of the pressure device 5 extends to prevent the locking sleeve A4 from moving upward. The lifting device 2 lifts the sensor pressure fixture A and presses down the locking sleeve A4 on the pressure fixture to lock it until the swing seat 51 is lifted. At this time, the torque on the pressure fixture is equivalent to the torque of the counterweight 521 on the pressure system. The servo screw descends, the locking sleeve A4 is locked, and the spring performance component A5 begins to maintain pressure.

[0040] The above structure enables automatic pressurization of sensor pressure fixture A, achieving automation and offering the following advantages:

[0041] 1. In traditional solutions, operators need to manually place a sensor into the pressure fixture, then place a partition, then place another sensor, and so on, until the pressure fixture is full. This patented technology eliminates this limitation, eliminating the need for operators to perform loading and unloading operations.

[0042] 2. In the traditional solution, an operator can only process one pressure fixture at a time. However, when using this patented technology, the operator only needs to put several empty pressure fixtures into the equipment at intervals and remove the full pressure fixtures.

[0043] 3. In traditional solutions, if a nut is used for locking under pressure, work efficiency is sacrificed; if a snap-lock is used, work quality is sacrificed. However, this patented solution automates the operation, reduces the labor intensity and workload of employees, is highly efficient and simple, and at the same time, has higher pressure holding accuracy.

[0044] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
