[0025] The utility model is further described below in conjunction with the accompanying drawings:

[0026] The directions described in the utility model specification, such as "up", "down", "left", "right", "front", "back", etc., are based on the directions of the drawings and are intended to facilitate the description of the relationship between the various components. They do not indicate the unique or absolute positional relationship between the various components. They are only one of the implementation methods of the utility model and are not a limitation on its implementation method.

[0027] like Figure 1 As shown, the sensor pressurizing jig A includes a base plate A1, to which at least two slide bars A2 are connected, and a locking sleeve A3 is provided on the top of the slide bar A2. Multiple sensor pressurizing jigs A are sent to the pressurizing machine B. The pressurizing machine B can place the main material, the sensor, on the sensor pressurizing jig A, and pressurize each sensor pressurizing jig A through an automatic pressurizing structure.

[0028] This embodiment provides an automatic feeding device for a sensor pressurizing machine, such as Figure 1 As shown, the sensor press automatic loading device is labeled B1, which is mainly used to transport the sensor press jig A to the station of the press B. Figure 2The automatic feeding device of the sensor pressurizing machine shown in the figure includes a base 1, and two groups of clamping block groups 2 are arranged on the base 1, each group of clamping block groups 2 includes two clamping blocks 21, and the two clamping blocks 21 of each group of clamping block groups 2 are sandwiched to form a conveying channel 22 for the sliding rod A2 to pass through and can block the locking sleeve A3 from passing through, so that the sensor pressurizing jig A can be placed on the conveying channel 22, that is, the sliding rod A2 of the pressurizing jig A is placed on the conveying channel 22, and the locking sleeve A3 of the pressurizing jig A is stuck on the upper surface of the clamping block 21, so that the pressurizing jig A is hung between the two clamping blocks 21, and multiple pressurizing jigs A can be placed side by side.

[0029] like Figures 2 to 6 As shown, a pushing wheel 3 capable of rotating relative to the machine base 1 is provided at a position corresponding to the conveying channel 22 on the machine base 1, and the pushing wheel 3 is rotatably connected to the machine base 1. The pushing wheel 3 is circumferentially provided with a plurality of grooves 31 capable of supplying the slide rod A2 to enter, and the clamping blocks 21 are gradually inclined downward from the feeding end to the discharging end, so that the sensor pressurizing jig A moves under the action of gravity and pushes the pushing wheel 3 to rotate at the same time, that is, when the sensor pressurizing jig A slides downward along the inclined clamping block 21, the slide rod A2 of the sensor pressurizing jig A can enter the groove 31 of the pushing wheel 3, thereby pushing the pushing wheel 3 to rotate, and the shape of the groove 31 is set so that only one slide rod A2 of the sensor pressurizing jig A can enter at a time, and the machine base 1 is also provided with an intermittent mechanism 4 capable of blocking the rotation of the pushing wheel 3 after the pushing wheel 3 rotates a preset angle, so that the pushing wheel 3 stops rotating after rotating a certain angle, so that only one sensor pressurizing jig A moves from one side of the pushing wheel 3 to the other side at a time, realizing the function of conveying one by one.

[0030] As a preferred solution of this embodiment, Figures 5 to 8 As shown, the intermittent mechanism 4 includes a ratchet 41, a rocker rod 42 rotatably connected to the machine base 1, and a driving device 43 capable of pushing the rocker rod 42 to rotate. The ratchet 41 is connected to the pushing wheel 3. The ratchet 41 is provided with a plurality of ratchet teeth 411 along the circumferential direction, and a ratchet groove 412 is formed between two adjacent ratchet teeth 411. The rocker rod 42 is provided with a first pawl 421 which can be inserted into the ratchet groove 412 after it rotates by a preset angle. The driving device 43 pushes the rocker rod 42 to rotate so that the first pawl 421 enters the ratchet groove 412, thereby preventing the ratchet 41 from rotating, so that the pushing wheel 3 stops rotating after rotating a certain angle.

[0031] The rocker arm 42 may be provided with only one pawl, namely the first pawl 421, but this requires a preset time point for the driving device 43 to act so as to coincide with the time for the pushing wheel 3 to push a sensor pressurizing fixture A each time it rotates, otherwise the sensor pressurizing fixture A cannot be smoothly conveyed.

[0032] Therefore, as a preferred solution of this embodiment, Figures 5 to 8 As shown, the rocker arm 42 is also provided with a second pawl 422, and the first pawl 421 and the second pawl 422 are eccentrically arranged on both sides of the rotation center of the rocker arm 42, so that when the rocker arm 42 rotates forward by a preset angle, the first pawl 421 enters into one of the ratchet grooves 412 on the ratchet wheel 41, and when the rocker arm 42 rotates reversely by a preset angle, the second pawl 422 enters into another ratchet groove 412 on the ratchet wheel 41, that is, when the rocker arm 42 swings in one direction so that the first pawl 421 enters into one ratchet groove 412, the second pawl 422 escapes from one ratchet groove 412, and when the rocker arm 42 swings in the opposite direction so that the second pawl 422 enters into one ratchet groove 412, the first pawl 421 escapes from one ratchet groove 412. Through the above structure, it is only necessary to set the driving device 43 to reciprocate so that the rocker arm 42 swings back and forth. In this way, during the action, the first pawl 421 moves toward the ratchet wheel 41 until it enters a ratchet groove 412. At this time, the push wheel 3 rotates until it is blocked by the first pawl 421. Then the rocker arm 42 causes the second pawl 422 to move toward the ratchet wheel 41 until it enters a ratchet groove 412. At this time, the push wheel 3 rotates until it is blocked by the second pawl 422, thereby realizing the intermittent action of the push wheel 3.

[0033] Of course, as another implementation of the intermittent mechanism 4, a servo motor directly connected to the pushing wheel 3 can be provided, and the pushing wheel 3 can be intermittently moved through the intermittent action of the servo motor.

[0034] As a preferred solution of this embodiment, the driving device 43 may adopt a telescopic motor, such as the solution provided by the patent with patent number CN202223558959.6 and the name of hexagonal fixed-axis telescopic stepping motor; the driving device 43 may also adopt a telescopic cylinder, such as the solution provided by the patent with patent number CN200720198905.X and the name of telescopic cylinder; the driving device 43 may also adopt a telescopic hydraulic cylinder, such as the solution provided by the patent with patent number CN201710965961.X and the name of a telescopic hydraulic. Figure 2 and Figure 7 As shown, the driving device 43 is rotatably connected to the machine base 1, and the output shaft of the driving device 43 is rotatably connected to the swing rod 42, so that when the output shaft of the driving device 43 is extended and retracted, it can push the swing rod 42 to swing back and forth.

[0035] Of course, the driving device 43 may also be a general rotary motor, and the output shaft of the rotary motor may be connected to the rotation center of the swing rod 42 .

[0036] As a preferred solution of this embodiment, Figures 2 to 4As shown, the base 1 is provided with a first proximity sensor 5 for sensing the sensor pressurizing fixture A on one side of the conveying channel 22. The first proximity sensor 5 is connected to one of the clamping blocks 21. The sensing end of the first proximity sensor 5 is exposed in the conveying channel 22, so as to sense the passage of the sensor pressurizing fixture A, so as to adjust and control the pushing wheel 3 according to the frequency of the sensor pressurizing fixture A passing by. A proximity sensor is a sensor used to detect when an object is approaching or moving away. The sensor can detect the presence of an object without actually touching the object. The following types of proximity sensors can be used: Infrared sensor: Uses infrared to detect the presence or distance of an object. When an object approaches the sensor, it reflects infrared, 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. The sensor determines the distance of the object by calculating the time of the echo; Inductive sensor: Determines its position or distance by detecting the effect of the object 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 an object. When an object approaches the sensor, it changes the capacitance of the sensor, thereby triggering the sensor; Magnetic sensor: Uses the effect of an object on the magnetic field to detect its position or distance. When an object approaches the sensor, it changes the magnetic field strength felt by the sensor, thereby triggering the sensor.

[0037] As a preferred solution of this embodiment, Figures 2 to 4 As shown, a guide slope 6 is provided on the machine base 1 below the discharge end of the conveying channel 22, and the guide slope 6 is gradually inclined downward from the feed end of the conveying channel 22 to the discharge end of the conveying channel 22, so that after the sensor pressurizing fixture A moves from the conveying channel 22 to the discharge end of the conveying channel 22, the sensor pressurizing fixture A can slide along the guide slope 6 to the set position to discharge.

[0038] As a preferred solution of this embodiment, Figures 2 to 4 As shown, a slide plate 7 for placing the sensor pressurizing jig A is provided on one side of the discharge end of the guide slope 6 on the machine base 1. The machine base 1 is also provided with a pushing mechanism 8 capable of pushing the sensor pressurizing jig A to move along the slide plate 7, so that the sensor pressurizing jig A slides along the guide slope 6 toward the discharge direction onto the slide plate 7, and the discharged sensor pressurizing jig A is transported to a set position along the slide plate 7 through the pushing mechanism 8, which can assist the sensor pressurizing jig A in discharging or transport the sensor pressurizing jig A to the next process.

[0039] As a preferred solution of this embodiment, Figures 2 to 4 As shown, the pushing mechanism 8 includes a linear module 81 arranged along the length direction of the slide rail plate 7. The linear module 81 can refer to the linear module in the patent scheme with patent number CN201420134799.9 and the name of the linear module protective cover. The linear module 81 has a sliding table 811 that can slide linearly. The sliding table 811 is connected to a push block 82 for pushing the sensor pressurizing fixture A to move. When this structural design is adopted, some beneficial effects and advantages are brought about: Precise control: Through the design of the linear module, precise control of pushing the sensor pressurizing fixture A can be achieved to ensure that it can be accurately applied during processing or testing. Add pressure or move; Automation function: The design of the push mechanism can be integrated with the automation system to realize processing and operation on the automated production line, improve production efficiency and reduce labor costs; Improve production efficiency: Through the use of the push mechanism, the sensor pressurizing fixture A can be moved quickly and accurately, thereby improving production efficiency and reducing production cycles; Reliability and stability: Linear modules usually have high reliability and stability, can operate stably for a long time without failure, and ensure the continuity of the production process; Save space: Linear modules are usually compact in design, can save space and are suitable for various working environments, providing more flexibility for production line layout. In general, this push mechanism solution can improve production efficiency, accurately control the processing process, realize automated operation, and has the characteristics of stability and reliability, which is suitable for various production scenarios.

[0040] As a preferred solution of this embodiment, Figures 2 to 4As shown, the slide plate 7 is provided with a second proximity sensor 9 for sensing the sensor pressurizing fixture A. When the sensor pressurizing fixture A moves to the slide plate 7, the second proximity sensor 9 can sense the passage of the sensor pressurizing fixture A, and the sensor pressurizing fixture A is pushed along the slide plate 7 in combination with the pushing mechanism 8 arranged along the length direction of the slide plate 7. In this way, when the sensor pressurizing fixture A moves to the slide plate 7, the second proximity sensor 9 will sense its passage and trigger the pushing mechanism 8 to push it. This structure realizes the automatic processing and transportation of workpieces or equipment through the cooperation of sensors and pushing mechanisms. This system can improve production efficiency and reduce manual intervention, thereby achieving the purpose of automated production. Introduce more sensor technologies: In addition to the second proximity sensor, other types of sensors, such as photoelectric sensors, pressure sensors, etc., can also be considered to be installed on the slide plate to realize the monitoring and control of different parameters; Push mechanism optimization: By optimizing the design and control system of the pushing mechanism, the sensor pressurizing fixture A can be accurately pushed and positioned to improve the operating stability and efficiency of the overall system; Data acquisition and analysis: Introduce data acquisition equipment to monitor the working status of the sensor and the pushing mechanism in real time, optimize the production process through data analysis, prevent failures and improve production efficiency; Improve production efficiency: The automated pushing system can reduce manual intervention, speed up production, reduce production costs and improve production efficiency; Precise control and positioning: Through the application of sensor technology, the sensor pressurizing fixture A can be accurately controlled and positioned to ensure the accuracy and stability of the production process; Reduce human errors: The automated system reduces the possibility of human operation, reduces production quality problems caused by human errors, and improves product quality and consistency.

It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
