Description

Technical Field

[0001] This utility model relates to the field of sensor production equipment technology, specifically to a feeding mechanism for a sensor assembly and testing machine. Background Technology

[0002] In the sensor manufacturing and assembly testing process, the feeding mechanism, as an important component of the automated production line, directly affects the overall production efficiency and assembly accuracy. Traditional feeding methods mostly rely on manual feeding or simple mechanical pushing devices, which suffer from problems such as unstable feeding, inaccurate positioning, and poor adaptability, making it difficult to meet the needs of modern high-precision, high-speed, and multi-variety sensor assembly and testing equipment.

[0003] Simple automated feeding: Some feeding mechanisms using vibratory feeders and linear feeders achieve preliminary automation, but they lack flexibility in adapting to the diverse specifications of sensors (such as different sizes, shapes, and pin layouts). When changing sensor models, cumbersome adjustments to the feeding track and positioning structure are required, resulting in long downtime for model changes and hindering the improvement of production efficiency. Furthermore, during the lifting and conveying process, due to structural design defects (such as independent operation of the lifting and guiding mechanisms and lack of synchronous constraints), problems such as tilting of the feeding tray and sensor misalignment and jamming are prone to occur, affecting the accuracy and stability of feeding and thus interfering with the normal operation of the assembly and testing process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3 The present invention relates to a feeding mechanism for a sensor assembly and testing machine, comprising a frame 1, a lifting mechanism, a feeding tray 8, and a guiding mechanism. The lifting mechanism includes a lifting cylinder 2, a lifting guide rod 10, and a lifting base 3. The lifting cylinder 2 is installed at the top of the frame 1, and the lifting base 3 is installed at the output end of the lifting cylinder 2. The lifting guide rod 10 is fixedly installed on the side of the lifting base 3 and is fixedly connected to the guiding mechanism. The guiding mechanism includes a guide rail 6 and a transmission mechanism. The guide rail 6 is located on the side of the feeding tray 8, and the feeding tray 8 is slidably connected to the guide rail 6 through the transmission mechanism.

[0025] This technical solution uses a lifting mechanism to drive the guide rail 6 to move up and down, and combines a transmission mechanism to drive the feeding tray 8 to slide along the rail, thereby achieving automatic lifting, positioning and precise conveying of the sensor components.

[0026] This organization mainly includes:

[0027] Rack 1

[0028] As the main support for the equipment, it provides the installation benchmark; windows are provided on both sides of the frame 1 to allow the guide rail 6 to pass through, ensuring the linkage space between the guide mechanism and the lifting mechanism.

[0029] Lifting mechanism

[0030] Mounted at the top of frame 1, enabling the vertical lifting of the feeding tray 8, including:

[0031] Lifting cylinder 2: provides lifting power and drives the lifting base 3 to move up and down;

[0032] Lifting guide rod 10: fixed to the side of the lifting base 3, rigidly connected to the guide mechanism, and synchronously transmits lifting displacement;

[0033] Lifting base 3: Bears the lifting load of the feeding tray 8 and serves as the connecting carrier between the lifting cylinder 2 and the guide mechanism;

[0034] Lifting telescopic rod (preferred): includes telescopic outer rod 4 (fixed to the top side of the frame 1) and telescopic inner rod 5 (slidably fitted onto the outer rod and fixedly connected to the lifting base 3), and auxiliary lifting guide rod 10 to enhance lifting stability and prevent the lifting base 3 from tilting.

[0035] Feeding tray 8

[0036] The material tray 7, which is used to carry the sensor, is placed on the inner side of the guide rail 6. The tray is equipped with several sensor assembly slots 9 (to accommodate sensors of different specifications, and the slot type and spacing can be designed as needed) to achieve the pre-positioning of the sensor.

[0037] Guiding agency

[0038] Ensuring the horizontal guiding and conveying of the 8-piece feeding tray includes:

[0039] Guide rail 6: runs through the windows on both sides of the frame 1, and a material tray rack 7 is provided on the inner side for placing the loading tray 8. The rail is fixedly connected to the lifting guide rod 10 to realize synchronous linkage of "lifting-guiding"; a guide groove 13 is provided at the bottom of the rail.

[0040] Transmission mechanism: includes drive motor 11 (fixed on the side of material tray frame 7), drive gear 12 (installed on the motor output end), and transmission rack 14 (fixed on the inside of guide rail 6). Through gear and rack transmission, the material tray frame 7 (and loading tray 8) is driven to slide along the guide rail 6.

[0041] Pulley 15 and guide groove 13 (preferred): Pulley 15 is hinged to the bottom of the tray frame 7 and embedded in the guide groove 13 of the guide rail 6 to form a sliding constraint, thereby enhancing the smoothness and stability of sliding.

[0042] Working principle of the preferred technical solution

[0043] The linkage principle between the lifting mechanism and the guiding mechanism

[0044] When the lifting cylinder 2 extends or retracts, the lifting base 3 drives the lifting guide rod 10 to move vertically. Since the lifting guide rod 10 is fixedly connected to the guide rail 6, the guide rail 6 rises and falls synchronously. At the same time, the inner extension rod 5 of the lifting extension rod moves with the lifting base 3 and slides along the outer extension rod 4, which helps to constrain the movement trajectory of the lifting base 3, avoids tilting, and ensures the stability of the lifting process.

[0045] When the guide rail 6 is raised and lowered, the material tray frame 7 and the loading tray 8 on it are raised and lowered synchronously, so as to adjust the position of the loading tray 8 in the vertical direction and prepare for the horizontal conveying of the sensor.

[0046] Guiding principle of transmission mechanism

[0047] When the drive motor 11 starts, the output end drives the gear 12 to rotate, which meshes with the transmission rack 14 inside the guide rail 6, converting the motor torque into the horizontal displacement of the material tray frame 7 (and the loading tray 8), so that the loading tray 8 slides along the guide rail 6.

[0048] The bottom pulley 15 of the material tray frame 7 slides along the guide groove 13 of the guide rail 6, forming a dual guide of "gear and rack transmission + groove constraint", which ensures the linear motion accuracy of the loading tray 8 and prevents it from deviating or jamming during horizontal conveying.

[0049] The adaptation principle between sensor assembly slot 9 and material tray 7

[0050] The sensor assembly slot 9 on the feeding tray 8 is designed according to the shape and size of the sensor. By replacing the feeding tray 8 with different slot types (or adjusting the slot structure), it can be adapted to feed sensors of various specifications. The feeding tray 8 is placed on the tray frame 7 inside the guide rail 6. The tray frame 7 provides a support and installation foundation for the feeding tray 8, which facilitates the replacement and maintenance of the feeding tray 8 and further improves the versatility of the equipment.

[0051] Detailed Workflow

[0052] Initialization preparation: Place the loading tray 8 equipped with the sensor (the sensor is placed in the assembly slot to complete the pre-positioning) on ​​the tray frame 7 inside the guide rail 6 to ensure that the loading tray 8 is stably supported; at this time, the loading tray 8 and the tray frame 7 are in the initial position of the guide rail 6, waiting for the feeding command.

[0053] Lifting and Adjustment: When the lifting cylinder 2 is activated, it pushes the lifting base 3 downward, which drives the guide rail 6 to descend synchronously through the lifting guide rod 10 (the inner telescopic rod 5 of the lifting telescopic rod slides along the outer telescopic rod 4 to help maintain stability), so that the feeding tray 8 is close to the vertical height of the feeding station; if the height needs to be adjusted, the lifting cylinder 2 can reverse the action to drive the feeding tray 8 to rise and reset or readjust.

[0054] Horizontal guiding conveying: When the drive motor 11 starts, the drive gear 12 meshes with the transmission rack 14, driving the material tray frame 7 and the loading tray 8 to slide along the guide rail 6 (the bottom pulley 15 of the material tray frame 7 is guided by the guide groove 13), accurately conveying the sensor on the loading tray 8 to the assembly and testing station; during the conveying process, the double guiding structure ensures the motion accuracy and avoids sensor deviation.

[0055] Material feeding completion and reset: After the sensor completes the feeding, the drive motor 11 reverses and drives the material tray frame 7 and the feeding tray 8 to return to the initial position along the guide rail 6; then, the lifting cylinder 2 is activated, the lifting mechanism rises and resets, and prepares for the next round of feeding; if the feeding tray 8 needs to be replaced, the feeding tray 8 that has been fed can be taken out from the initial position, and the feeding tray 8 equipped with the new sensor can be replaced to continue the cycle of feeding.
