Description

Technical Field

[0001] This utility model relates to the field of wheel speed sensor technology, and in particular to an ABS wheel speed sensor chip clamping device. Background Technology

[0002] ABS wheel speed sensors are widely used in the ABS systems of various motor vehicles and are one of the key components for the normal operation of the ABS system. They can monitor the wheel speed in real time, providing accurate information to the ABS control unit, thereby ensuring the stability and safety of the vehicle during braking.

[0003] Chinese Patent CN215473262U discloses a clamping device for producing ABS wheel speed sensors, including a conveyor belt and a clamping mechanism. The conveyor belt has a clamping assembly on its surface, and a fixed clamping component is located on the left side of the movable clamping component. A sensor housing is located inside the left side of the movable clamping component. The clamping mechanism is positioned above the conveyor belt. An outer tube is connected to the bottom of an electric lifting rod. A hollow layer is formed on the inner wall of the outer tube, and a second spring is located inside the hollow layer. A limiter is fixed to the bottom of the second spring. A suction cup is fixed inside the outer tube, and a chip body is connected to the bottom of the suction cup. This clamping device for producing ABS wheel speed sensors uses laser positioning and limiter adsorption to precisely clamp the chip body to a designated position inside the sensor housing. After the clamping operation, the sensor housing automatically detaches from the clamping assembly as it is transported by the conveyor belt, achieving unloading.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the existing ABS wheel speed sensor chip clamping device requires the operator to place the sensor chip on the conveyor belt for clamping, and during the clamping process, the conveyor belt transportation may cause the clamping position to deviate, resulting in poor clamping effect.

This can accurately transport the sensor chips from one station to another, thereby reducing the time and error of manual operation, significantly improving production efficiency, and avoiding clamping accuracy problems caused by improper manual operation. It also helps to ensure good contact and signal transmission between the sensor chips and other components of the ABS system. Furthermore, the slots can limit the sensor chips and prevent them from slipping after the conveyor belt stops, which would lead to inaccurate clamping positions.

[0023] 2. Through the intermittent switching mechanism and the clamping mechanism, the motor drives the pressing plate to rotate intermittently, thereby intermittently opening the transport switch and controlling the movement of the transport belt. At the same time, it drives the intermittent pressing component to rotate, thereby driving the clamping device to press down and clamp the sensor chip. This can prevent vibration or interference caused by movement, ensure that the clamping process is carried out in a stable environment, avoid deviations or misalignments that may occur during movement, thereby improving the clamping accuracy. Moreover, the next transport can start immediately after each clamping is completed, realizing efficient assembly line operation, making it easier to adapt to different production rhythms and needs, and improving production flexibility.

Detailed Implementation

[0029] Example 1

[0030] like Figures 1-3 As shown, the present invention proposes an ABS wheel speed sensor chip clamping device, which includes a workbench 1, table legs 2 disposed at the bottom of the workbench 1, a conveyor belt 301, an intermittent switching mechanism, and a clamping mechanism.

[0031] The conveyor belt 301 is slidably disposed on the outside of the workbench 1. Multiple slots 304 are equidistantly arranged on the conveyor belt 301. The inner wall width of the slots 304 is the same as that of the sensor chip. The slots 304 are used to store the sensor chip and transport it under the action of the conveyor belt 301.

[0032] An intermittent switch mechanism is located on the side of the workbench 1 and is used to intermittently open the conveyor belt 301;

[0033] The clamping mechanism is located on the side of the intermittent switching mechanism and is used to intermittently clamp the sensor chip under the drive of the intermittent switching mechanism.

[0034] The material storage assembly includes a connecting frame 303 and a feeding tube 302. The connecting frame 303 is located on the top of the workbench 1, and the feeding tube 302 is located at the end of the connecting frame 303 away from the workbench 1. The inner wall width of the feeding tube 302 is slightly larger than that of the sensor chip. The sensor chips are stacked together and placed inside the feeding tube 302. The distance from the feeding tube 302 to the conveyor belt 301 is slightly less than the thickness of the sensor chip. Therefore, the sensor chip will only fall into the slot 304 for transportation when the slot 304 moves to the bottom of the feeding tube 302. At other times, it is blocked inside the feeding tube 302, thereby realizing the transportation of the sensor chips one by one.

[0035] The intermittent switching mechanism includes a power component and an intermittent switching component. The power component is located on the side of the workbench 1 and provides power to the intermittent switching component. The intermittent switching component is located outside the power component and is used to intermittently open the conveyor belt 301. The power component includes a motor 501, a second connecting frame 502, a third connecting frame 503, and a first rotating shaft 507. The third connecting frame 503 is located on the side of the workbench 1, the second connecting frame 502 is located on the side of the third connecting frame 503, the motor 501 is located inside the second connecting frame 502, the first rotating shaft 507 is located at the output end of the motor 501, a mounting rod 504 is rotatably mounted on the outside of the first rotating shaft 507, a second spur gear 510 is rotatably mounted on the side of the mounting rod 504, a connecting shaft 505 is rotatably mounted on the bottom of the mounting rod 504, and a first spur gear 506 is mounted at the end of the connecting shaft 505. The top of the first spur gear 506 meshes with the bottom of the second spur gear 510. The intermittent switch assembly includes an actuating lever 512, a toggle block 511, a guide frame 508, and an arc-shaped block 509. The actuating lever 512 is located on the side of the spur gear 506 away from the mounting rod 504. The toggle block 511 is located at the end of the actuating lever 512. The guide frame 508 is located on the side of the transfer tray and has a sliding groove. The arc-shaped block 509 is located on the side of the guide frame 508. A collar 516 is located at the axis of the guide frame 508. The inner side of 16 is rotatably connected to the end of the rotating shaft 507 away from the motor 501, which is used to further limit the position of the rotating shaft 507 and ensure the stable rotation of the rotating shaft 507. A connecting block 513 is provided on the side of the guide frame 508 away from the rotating shaft 507, and a pressing plate 514 is provided on the end of the connecting block 513 away from the guide frame 508. A transport switch 515 is provided on the side of the worktable 1. When the motor 501 is started, the motor 501 drives the rotating shaft 507. 7. Rotating within the mounting rod 504, the rotating shaft 507 drives the second spur gear 510 to rotate, the second spur gear 510 drives the first spur gear 506 to rotate, the first spur gear 506 drives the actuating rod 512 to rotate, and the actuating rod 512 drives the toggle block 511 to rotate. The guide frame 508 is provided with a sliding groove, the inner wall width of which is slightly larger than the diameter of the toggle block 511. Therefore, when the toggle block 511 slides in the sliding groove on the guide frame 508, it drives the guide frame 508 to rotate. The guide frame 508 drives the pressing plate 514 to rotate through the connecting block 513. When it disengages from the sliding groove, the actuating rod 512 spins freely and cannot drive the guide frame 508 to rotate. The guide frame 508 rotates 90 degrees each time. The transport switch 515 is located on the rotation trajectory of the pressing plate 514 and is on the same plane as the pressing plate 514. Therefore, when the pressing plate 514 rotates to the vicinity of the transport switch 515, it can press the transport switch 515 to open the transport belt 301.

[0036] Example 2

[0037] like Figure 4As shown, this utility model proposes an ABS wheel speed sensor chip clamping device. Compared with Embodiment 1, this embodiment details the structure of the clamping mechanism.

[0038] The clamping mechanism includes a mounting platform 401, a second rotating shaft 402, a drive wheel 403, and a transmission belt 404. The second rotating shaft 402 is located at the axis of the guide frame 508 and on the side of the guide frame 508 away from the collar 516. The drive wheel 403 is located at the end of the second rotating shaft 402 away from the guide frame 508. The transmission belt 404 is located on the outside of the drive wheel 403. A driven wheel 405 is located on the side of the transmission belt 404 away from the drive wheel 403. An intermittent pressing element 406 is located on the side of the driven wheel 405. 406 has four protruding ends, each with an arc-shaped end to facilitate contact with and movement of the connecting rod 411. The mounting platform 401 is located on the side of the workbench 1. A telescopic tube 408 is mounted on the top of the mounting platform 401, and a spring 409 is mounted on the outer side of the telescopic tube 408. The length of the spring 409 is the same as the length of the telescopic tube 408. A sliding plate 410 is mounted on the top of the telescopic tube 408, and a straight slide rail 407 is slidably mounted on the outer side of the sliding plate 410. A connecting rod is mounted at the end of the sliding plate 410. 411, the end of the connecting rod 411 near the straight slide rail 407 is located on the rotation trajectory of the intermittent pressing member 406. Therefore, when the intermittent pressing member 406 rotates to the connecting rod 411, it will press down on the connecting rod 411. A clamping device 412 is provided on the top of the connecting rod 411. The guide frame 508 drives the rotating shaft 402 to rotate, the rotating shaft 402 drives the driving wheel 403 to rotate, the driving wheel 403 drives the driven wheel 405 to rotate through the transmission belt 404, and the driven wheel 405 drives the intermittent pressing member 406 to rotate. The rotation amplitude and rotation time of 06 are synchronized with the pressing plate 514. When the pressing plate 514 is disengaged from the switch, the intermittent pressing component 406 just begins to press the connecting rod 411. The connecting rod 411 slides on the straight slide rail 407 and drives the clamping device 412 to press down. The clamping device 412 clamps the sensor chip. At this time, the spring 409 and the telescopic tube 408 are compressed. The intermittent pressing component 406 can continue to rotate and disengage from the connecting rod 411. The connecting rod 411 returns to its original position under the action of the spring 409 and the telescopic tube 408.

[0039] In summary, when using this invention, the sensor chips are stacked together and placed inside the feeding pipe 302. The sensor chip at the bottom will fall into the slot 304 on the conveyor belt 301. The motor 501 is started, driving the rotating shaft 507 to rotate within the mounting rod 504. The rotating shaft 507 drives the second spur gear 510 to rotate, which in turn drives the first spur gear 506 to rotate. The first spur gear 506 drives the actuating rod 512 to rotate, which in turn drives the toggle block 511 to rotate. When the toggle block 511 slides in the groove on the guide frame 508, it drives the guide frame 508 to rotate. The guide frame 508 drives the pressing plate 514 to rotate via the connecting block 513. When disengaged from the groove, the actuating rod 512 spins freely, thus failing to drive the guide frame 508 to rotate. The guide frame 508 rotates 90 degrees each time, and the pressing plate 514 rotates to the conveyor belt. When near switch 515, press transport switch 515 to open transport belt 301. After transport belt 301 is opened, it drives the sensor chip in slot 304 to move. At the same time, guide frame 508 drives rotating shaft 402 to rotate. Rotating shaft 402 drives driving wheel 403 to rotate. Driving wheel 403 drives driven wheel 405 to rotate through transmission belt 404. Driven wheel 405 drives intermittent pressing component 406 to rotate. Intermittent pressing component 406 drives clamping device 412 to press down through connecting rod 411. Clamping device 412 clamps the sensor chip transported to the clamping device 412. At this time, spring 409 and telescopic tube 408 are compressed. Intermittent pressing component 406 continues to rotate and can disengage from connecting rod 411. Connecting rod 411 returns to its original position under the action of spring 409 and telescopic tube 408, and then the clamping work of the next sensor chip is carried out.

[0040] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
