Description

Technical Field

[0001] This utility model relates to the field of terminal crimping technology, and in particular to a laser sensor terminal crimping and mounting device. Background Technology

[0002] With the rapid development of laser scanning technology, laser scanning sensors are widely used in various fields, especially with the widespread adoption of intelligent devices such as smart factories, intelligent transportation, autonomous driving, and smart equipment. These sensors scan external objects, collecting data which is then fed back to a host computer for analysis, enabling a series of judgments and realizing the intelligent functions of mechanical equipment. This necessitates more convenient and rapid assembly of laser scanning sensors. Therefore, a device is needed to quickly and accurately position the wiring and cables during laser sensor assembly.

[0003] Currently, when installing terminals, they are generally pressed manually in sequence. However, some special models cannot be pressed one by one and require installation in empty spaces, which easily leads to errors such as incorrect or missing terminals. Therefore, there is an urgent need to develop a dedicated laser sensor terminal crimping and installation device to solve the pain points of existing technology and meet the actual needs of industry development and production. Based on this, this utility model proposes a laser sensor terminal crimping and installation device. Utility Model Content

[0015] like Figure 1-9 As shown, a laser sensor terminal crimping and mounting device includes a gantry frame 2 mounted above a mounting platform 1. A linear track mechanism 5 is mounted on the gantry frame 2. A lead screw mechanism is mounted at the front end of the linear track mechanism 5. A cylinder fixing component 6 is mounted on the lead screw mechanism, moving left and right. A cylinder 10 is mounted at the bottom of the cylinder fixing component 6. A connecting pressure plate 11 is mounted at the telescopic end of the cylinder 10. A terminal placement mechanism 8 mounted on the upper surface of the mounting platform 1 is adapted to the other end of the connecting pressure plate 11.

[0016] The lead screw mechanism includes support plates 4 symmetrically mounted on both sides of the linear track mechanism 5. A lead screw 13 is installed in the middle between the support plates 4, and limiting slide rods 14 are symmetrically distributed on both sides of the lead screw 13. A lead screw nut 12 is threaded onto the lead screw 13, and the upper and lower parts of the lead screw nut 12 are slidably mounted on the limiting slide rods 14. One end of the lead screw 13 extends out of the support plate 4 and is connected to a forward and reverse motor 3. Deep groove ball bearings are installed on the support plates 4 to support the stable rotation of the lead screw 13.

[0017] The linear track mechanism 5 includes a linear track 501, on which a track slider 502 is slidably mounted. The track slider 502 is mounted together with the nut block 12. The movement of the nut block 12 causes the track slider 502 to move accordingly.

[0018] The photoelectric sensing limit device 7 on the linear track 501 is used to detect the movement stroke of the track slider 502. It detects the movement stroke of the track slider 502 in real time and feeds back the position signal, ensuring that the track slider 502 drives the terminal pressing components to precisely stop at the pressing position corresponding to the sensor terminal. This avoids problems such as terminal offset and pin bending due to positional deviation, meeting the high pressing accuracy requirements of small laser sensor terminals. Simultaneously, the photoelectric sensing limit device 7 transmits the electrical signal of the track slider 502's stroke to the microcontroller control system 15, ensuring that the start / stop and movement speed of the track slider 502 (i.e., the terminal placement mechanism 8) are precisely matched with other processes on the automated production line. This prevents the production line from being slowed down due to chaotic movement rhythm of the track slider 502 (i.e., the terminal placement mechanism 8), ensuring that the terminal pressing process is efficiently and stably integrated into the overall automated process.

[0019] A microcontroller control system 15 is installed on one side of the mounting platform 1. The microcontroller control system 15 is electrically connected to the forward and reverse motor 3 and the photoelectric induction limit device 7. A foot switch 9 for controlling the air circuit switch of the cylinder 10 is installed at the front end of the microcontroller control system 15. As the core, the microcontroller control system 15 can receive the stroke signal of the photoelectric induction limit device 7 and accurately control the operation of the forward and reverse motor 3 to ensure the positional accuracy of terminal crimping and equipment safety. The foot switch 9 allows the operator to control the air circuit switch of the cylinder 10 with their foot, freeing their hands to complete terminal positioning and other operations simultaneously. This improves the operational convenience of the crimping process, ensures the coordinated linkage of various components, and thus improves production efficiency and crimping quality stability, adapting to the needs of automated production.

[0020] The single-chip microcomputer control system 15 includes a power supply, a driver, a programmable controller, and a running switch. The components are flexibly electrically connected through wiring. The power supply provides stable power to the entire control system. The driver is used to receive control signals from the programmable controller and drive the actuators (such as the forward and reverse motor 3) to move. The programmable controller, as the core control unit, can accurately regulate the operation of each component according to the preset program and the signals fed back by the photoelectric sensing limit device 7. The running switch is used to realize the start and stop operation of the control system. Through the coordinated cooperation of all components, the automated and precise operation of the small laser sensor terminal crimping installation device is ensured.

[0021] The terminal placement mechanism 8 includes a positioning member 801. A positioning groove 805 matching the terminal 16 is formed on the side wall of the positioning member 801. A clamping piece 802 is installed at the opening of the positioning groove 805. The clamping piece 802 is connected to the positioning member 801 via a guide rod. Springs 804 are symmetrically installed on both sides of the guide rod, with one end of each spring 804 mounted on the positioning member 801 and the other end mounted on the clamping piece 802. An eccentric wheel locking wrench 803 is installed at the end of the guide rod that extends out of the clamping piece 802. The upper part of the clamping piece 802 interacts with the positioning groove 805 to clamp the terminal 16.

[0022] Specifically, by placing the terminal 18 in the positioning groove 805 and tightening the eccentric wheel locking wrench 803, the clamping plate 802 moves towards the positioning groove 805 and presses against the side wall of the terminal 16, thus achieving the clamping operation of the terminal 16; by releasing the eccentric wheel locking wrench 803, the braking of the clamping plate 802 is released, and the compressed spring 804 resets the clamping plate 802 through elastic deformation, making it convenient to remove the crimped terminal 16.

[0023] The working process of this utility model is as follows: First, power on the device and connect it to the air source. Select the appropriate operating program and ensure that the connecting pressure plate 11 is in the zero position (at this time, the photoelectric sensor switch 7 lights up). Then, loosen the eccentric wheel locking part, put the terminal into the positioning groove 805 of the positioning part 801, and then tighten the eccentric wheel locking part. Secondly, after locking is completed, stepping on the foot switch 9 causes the cylinder 10 to push outward. After receiving the signal, the microcontroller control system 15 drives the linear track mechanism 5 on the gantry 2 to work in coordination with the screw mechanism. The screw mechanism drives the cylinder fixing part 6 (and the cylinder 10 and connecting pressure plate 11 installed at the bottom) to move smoothly along the linear track, so that the pressure plate 11 runs according to the specified step distance set in the program. When the pressure plate 11 runs to the preset pressing position, the photoelectric sensing limit device 7 feeds back the position signal, prompting the operator to release the foot switch 9. Then, after releasing the foot switch 9, the cylinder 10 switches direction and retracts inward, which in turn compresses the terminal button in the terminal placement mechanism 8 through the connecting pressure plate 11; the operator accurately places the cable to be assembled into the installation position corresponding to the terminal button, thus completing the cable pre-positioning; Finally, press the foot switch 9 again, and the cylinder 10 will push outward, causing the connecting pressure plate 11 to release the terminal button. After the terminal button resets, the cable will be firmly fixed, completing a single cable installation. If continuous assembly is required, first confirm that the pressure plate 11 has returned to the corresponding position (which can be determined by the signal from the photoelectric sensor limit device 7), and then cycle through the actions of "pressing the switch (pressure plate in position) → releasing the switch (terminal button compressed) → releasing the cable → pressing the switch (fixing the cable)".

[0024] Once all terminals are assembled, the microcontroller control system drives the lead screw mechanism, cylinder 10, and other components to reset according to the preset program. This causes the pressure plate 11 and cylinder fixing part 6 to return to the zero position along the straight track. The photoelectric sensing limit device 7 lights up again, and the equipment waits for the next assembly operation.
