Description

Technical Field

[0001] This invention relates to the field of linear module technology, and more particularly to high-precision linear motion modules for intelligent equipment oriented towards machine vision. Background Technology

[0002] Machine vision linear motion modules are automated devices that combine linear motion and vision systems, and are widely used in precision inspection, automated assembly, and object handling. They typically utilize high-precision industrial cameras and vision algorithms for tasks such as target detection, positioning, and dimensional measurement. The vision system can help the module identify objects, detect defects, and even guide the correction of motion paths.

[0003] Linear modules are typically designed with slide rails, guide rails, servo motors, and transmission systems, enabling linear motion under precise control. Due to their high precision, high efficiency, and long service life, linear modules have become an important component of modern automated equipment. However, because the sliding module needs to move back and forth on the track, the track surface is often exposed. If foreign objects fall onto the track, it will not only cause wear during equipment operation but may also lead to equipment jamming. To address the issue of traditional exposed drive tracks being prone to motion obstruction due to foreign objects, we propose a novel high-precision linear motion module for machine vision-oriented intelligent equipment. Summary of the Invention

[0004] To overcome the aforementioned shortcomings of the prior art, the present invention aims to provide a novel linear motion module that reduces the probability of foreign objects getting stuck on the surface of the drive track. This invention provides a high-precision linear motion module for intelligent equipment oriented towards machine vision, including a carrying barrel and an outer shell frame with an upward-opening, rectangular box-shaped structure. A robotic arm is provided at the top of the carrying barrel, and a machine vision module is provided at the top of the robotic arm. Symmetrical lower rail seats two are fixed to the inner walls of the long sides of the front and rear sides of the outer shell frame near the bottom, and multiple equidistant connecting rods are fixed to the upper surface of the lower rail seats two. The top of the connecting rod on the same side is fixed to the same upper rail one that is parallel to the lower rail seat two on the same side. The two upper rails one are slidably connected to the same drive module. The lower surface of the edge plate at the top opening of the carrying barrel has mounting grooves near the four corners, and the drive module also includes a pulley group fixed in the mounting groove and adapted to the upper rail one on the same side. A guide tube is slidably connected to the bottom center of the bearing barrel, and an annular retaining ring is fixed near the top of the outer circumference of the guide tube. A compression spring is fixed between the lower surface of the annular retaining ring and the bottom of the bearing barrel. A long shaft extending horizontally between the lower surfaces of the two lower rail seats is provided at the bottom end of the guide tube, and both ends of the long shaft are provided with abutting rollers that roll and fit against the lower surfaces of the lower rail seats. An arc-shaped recess is reserved at one end of the outer wall of the bearing barrel near the outer frame, and two mutually symmetrical shaft seats are fixed near the center of the arc-shaped recess. The same transmission rod is rotatably connected to the middle of the shaft seats. Both ends of the transmission rod are fixed with drive gears, and the upper surfaces of the two lower rail seats are reserved with teeth that mesh with the drive gears on their respective sides.

[0005] Furthermore, a motor mounting frame is inserted and fixed above the arc-shaped recess on the outer wall of the bearing barrel, and a servo motor is fixed in the middle of the motor mounting frame. A downwardly extending worm sleeve is fixed to the end of the output shaft of the servo motor, and a worm wheel disk that meshes with the worm sleeve is sleeved and fixed in the middle of the transmission rod. Through the cooperation between the worm wheel disk and the worm sleeve, when the device is used vertically, it can play a self-locking role after power is cut off, which provides a safety protection for the machinery and equipment fixed on the device.

[0006] Furthermore, the bottom center of the carrying barrel has a circular hole with a diameter larger than that of the guide slide tube, and a sliding bearing is embedded in the circular hole. The bottom end of the guide slide tube is fixed with a bearing seat, and anti-detachment bearings are respectively embedded at the front and rear ends of the bearing seat. The long shaft is rotatably connected to the two anti-detachment bearings. The lower surfaces of the two lower rail seats are respectively reserved with parallel lower rails, and the outer circumference of the abutting roller is reserved with an annular groove that engages with the lower rails. The top of the carrying barrel is fixed with a top cover, and a protruding post is fixed in the middle of the lower surface of the top cover. The protruding post is slidably inserted into the top opening of the guide slide tube. The upper surfaces of the two upper rails are respectively reserved with parallel convex rib rails, and the length of the two convex rib rails is the same as the overall length of the upper rails. The pulley group includes anti-detachment rollers that are rolled and engaged on the corresponding convex rib rails. Through the anti-detachment rollers and abutting rollers, the carrying barrel maintains longitudinal stability and does not slip when sliding, thereby improving the overall control accuracy of the equipment.

[0007] Furthermore, the outer circumferential wall of the guide tube is provided with a self-locking thread near the top, and the annular retaining ring is screwed onto the outer circumferential wall of the guide tube. The outer circumferential wall of the guide tube is also provided with a top nut on the upper surface of the annular retaining ring. By adjusting the distance between the annular retaining ring and the bottom of the barrel, the clamping roller can fit more tightly with the lower surface of the lower rail seat, thereby improving the load-bearing capacity of the equipment.

[0008] Furthermore, an outer tube extending horizontally to the other end is fixed to the front of the outer casing near one end, and the length of the outer tube is equal to half the length of the outer casing. A blocking plate is fixed to the starting end of the outer tube, and an inner sliding rod is slidably inserted into the other end of the outer tube. A compression spring is provided at one end of the inner sliding rod near the blocking plate, and an anti-detachment guide wheel is provided at the other end of the inner sliding rod. The disc of the anti-detachment guide wheel is perpendicular to the bottom of the outer casing. A flexible cable is wound around the outer circumference of the anti-detachment guide wheel, and one end of the flexible cable is fixed below the starting end of the outer tube, while the other end of the flexible cable is fixed to the side of the servo motor. A side cover is also provided on the front of the outer casing, and a wire-passing hole with the same length as the opening of the outer casing is reserved at the top of the side cover. By setting an anti-detachment guide wheel that is stepped forward by a compression spring, the drive module moving back and forth can be prevented from getting tangled with the flexible cable that supplies power to it during use.

[0009] Furthermore, multiple equally spaced recessed grooves are provided on the inner walls of the front and rear sides of the outer casing frame, and the size of the recessed grooves is adapted to the length and width of the corresponding connecting support rod.

[0010] Furthermore, side guard edges are reserved on the edges of the front and rear sides of the outer casing frame where the long sides are far apart, and multiple equally spaced drainage holes are opened on the upper track. The top of the front and rear sides of the outer casing frame has through holes corresponding to the drainage hole positions, which can discharge excess dust or oil during cleaning. Cleaning mechanisms are fixed on the lower surfaces of the front and rear side plates of the carrying bucket, and the cleaning mechanisms are located above the corresponding convex track. The cleaning mechanism includes a main tube sleeve with an opening facing the whole and a barrel-shaped structure. The bottom of the main tube sleeve is fixed to the lower surface of the side plate of the carrying bucket by screws. An inner sliding column is slidably inserted into the bottom opening of the main tube sleeve, and a brush head is fixed at the bottom end of the inner sliding column. The top of the inner sliding column and the bottom of the main tube sleeve are fixed with the same return spring. Through the cleaning mechanism, as the carrying bucket moves left and right, the upper surface of the upper track is cleaned in real time, thereby preventing foreign objects or dust from accumulating on the convex track.

[0011] Furthermore, both ends of the transmission rod are provided with threaded holes, and L-shaped screws are inserted into both threaded holes. The ends of the two L-shaped screws away from the transmission rod are provided with long bristles. The L-shaped screws are made of bending-resistant metal material. In use, the vertical end of the L-shaped screw is slightly bent so that the long bristles can not only pick up the oil at the bottom, but also contact the tooth peak of the drive gear when they are turned up to the highest point, thereby intermittently lubricating it.

[0012] Furthermore, an oil-absorbing sponge is fixed to the bottom of the outer casing frame, and the upper surface of the oil-absorbing sponge is higher than the plane where the lowest roller surface of the pressing roller is located. This allows the oil-absorbing sponge to pick up lubricating grease at any time when the pressing roller passes by, and to make timely contact with the lower track at its top.

[0013] Furthermore, an oil scraping mechanism is provided on the side of the lower surface of the bearing barrel away from the arc-shaped recess. The oil scraping mechanism includes a shaft frame two fixed in the middle of the lower surface of the bearing barrel. The shaft frame two has an overall "7" shape structure. A horizontal shaft is rotatably connected to the bottom end of the shaft frame two. Fixed plates are fixed at both ends of the horizontal shaft. The same pressure rod is fixed at the end of the two fixed plates away from the horizontal shaft. A return spring two is fixed at the end of the two fixed plates away from the horizontal shaft. A guide wheel frame is fixed at the end of the two return spring two away from the fixed plates. Rollers are provided at the top of the guide wheel frame. A permanent magnet is fixed in the middle of the pressure rod. An electromagnet is fixed on the lower surface of the horizontal plate of the shaft frame two. When the electromagnet is energized, the magnetic pole at its bottom end repels the magnetic pole at the end of the permanent magnet that is close to it.

[0014] The beneficial effects of this invention are as follows: 1. By setting the lower rail seat two inside the outer frame near the bottom, the lower rail seat two can be prevented from being directly exposed to the outside during use, thereby reducing the risk of foreign objects getting stuck. With the two clamping rollers at the bottom of the guide tube, not only can the vibration of the machine vision module caused by the equipment during operation be reduced, but the carrying bucket can also be firmly fixed in the outer frame, maintaining its smooth reciprocating operation and ensuring that the high-precision vision module can accurately identify or detect objects.

[0015] 2. By setting connecting support rods embedded in the inner groove to connect the upper rail one and the lower rail seat two, the overall bearing bucket is not affected by the deformation of the outer frame surface during operation, thereby improving the overall anti-collision performance of the device.

[0016] 3. By setting a fixed permanent magnet pressure rod, when this device needs to be installed vertically, in order to prevent the lubricating oil in the oil-absorbing sponge from falling and accumulating near the bottom due to gravity for a long time, when the carrying tank carrying the oil scraping mechanism moves to near the bottom, the electromagnet is energized. At this time, the suspended pressure rod will squeeze the middle of the oil-absorbing sponge. Then, as the carrying tank rises as a whole, the oil near the bottom can be slowly scraped to the top, so that the oil-absorbing sponge is evenly distributed with oil. Attached Figure Description
