[0027] Please see Figures 1-8 As shown, this utility model provides a linear slide 100, including a base 110 and a sliding assembly 130. The sliding assembly 130 includes a slide 140 and a slider 150. The base 110 includes a bottom wall 111 parallel to the slide 140, and a guide rail 120 is mounted on the bottom wall 111. The guide rail 120 is located at the centerline of the length direction of the base 110. The slider 150 is located directly below the slide 140 and is fixedly connected to the slide 140. 50 is slidably connected to the guide rail 120. The slider 150 has an installation groove 151 on the side facing away from the slide block 140. The installation groove 151 includes a groove top 1511 and groove walls 1512 extending from both sides of the groove top 1511 in the direction away from the slide block 140. The groove walls 1512 on both sides are symmetrically provided with insertion grooves 1513. The two sides of the insertion groove 1513 are provided with arc-shaped portions 1514. The guide rail 120 is provided with a protrusion 121, which is inserted into the insertion groove 1513.

[0028] The guide rail 120 is located at the centerline of the base 110 along its length. This symmetrical layout helps the slide 140 maintain linear motion during movement, avoiding offset caused by structural asymmetry and ensuring the accuracy of the movement. At the same time, by placing the guide rail 120 at the centerline of the base 110 along its length and the slider 150 directly below the slide 140, the linear slide 100 can maintain a relatively small overall width, which can meet the installation requirements of some equipment with limited space. Alternatively, while keeping the dimensions of the base 110 unchanged, the slide 140 can be made wider, enhancing the rigidity of the entire slide 140 and enabling it to remain stable under load, reducing bending and twisting, thereby improving load capacity. The fit between the mounting groove 151 and the protrusion 121 on the slider 150 makes the installation of the slider 150 and the guide rail 120 simpler and faster. Simply insert the slider 150 into the guide rail 120 and ensure that the protrusion 121 enters the insertion groove 1513. There is no need for complicated alignment and fixing procedures. At the same time, the design of the arc-shaped part 1514 can reduce stress concentration and reduce fatigue damage caused by excessive local stress, thereby improving the reliability and durability of the slide block 140.

[0029] In some embodiments, a protruding abutment portion 1515 is provided at one end of the groove wall 1512 away from the bottom of the groove, and a groove 122 is provided on the guide rail 120, into which the abutment portion 1515 is inserted. The insertion of the abutment portion 1515 into the groove 122 can effectively prevent the slide 140 from shifting or shaking during movement, ensuring that the slide 140 moves smoothly along the guide rail 120, improving the operational stability and reliability of the equipment. In addition, the cooperation between the abutment portion 1515 and the groove 122 can reduce the vibration and impact of the slide 140 during movement, thereby reducing the wear of components and extending the service life of the slide 140.

[0030] In some embodiments, the linear slide 100 further includes a drive unit, which includes a drive motor 180 and a synchronization device. The drive motor 180 is mounted at one end of the base 110 along its length. The synchronization device includes a synchronization pulley assembly 160 and a synchronization belt. The synchronization belt is rotatably connected to the synchronization pulley assembly 160 and fixedly connected to the slide 140. The drive motor 180 is mounted at one end of the base 110, and the synchronization device is connected to the slide 140. The overall layout is compact, saving space and facilitating integration with other equipment. For example, in space-constrained automated equipment, it can be flexibly arranged, improving the overall performance and space utilization of the equipment. The cooperation between the synchronization belt and the synchronization pulley assembly 160 accurately converts the rotational motion of the motor into the linear motion of the slide 140, achieving high-precision positioning.

[0031] In this embodiment, the synchronous pulley assembly 160 includes a first synchronous pulley 161, a second synchronous pulley 162, a first transmission pulley 164, and a second transmission pulley 165. The first synchronous pulley 161 is connected to the output shaft of the drive motor 180 and is located above the second synchronous pulley 162. In the vertical direction, the projection of the first synchronous pulley 161 coincides with the projection of the second synchronous pulley 162. The first synchronous pulley 161 and the second synchronous pulley 162 are connected by a belt 163. The second synchronous pulley 162 is connected to the first transmission pulley 164 by a drive shaft. The second transmission pulley 165 is located at the end of the slide block 140 away from the first transmission pulley 164. The synchronous belt is connected to the first transmission pulley 164 and the second transmission pulley 165 respectively. By vertically installing the first synchronous pulley 161 and the second synchronous pulley 162, this layout reduces the horizontal space occupied by the synchronous pulley assembly 160, making the structure of the entire drive unit more compact. This facilitates the installation and use of the linear slide 100 in a limited space, improving the space utilization of the equipment. The combination of belt drive and synchronous belt drive can effectively buffer and absorb the impact and vibration during the movement, making the slide table move more smoothly, reducing shaking and noise, and improving the reliability and service life of the equipment.

[0032] Furthermore, timing belt clamps 141 are fixedly connected to both ends of the slide 140 along its length. The timing belt is fixedly connected to the timing belt clamps 141. The timing belt clamps 141 include an upper clamp 1411 and a lower clamp 1412, and the timing belt passes between the upper clamp 1411 and the lower clamp 1412. The timing belt drives the slide 140 to slide relative to the base 110 through the timing belt clamps 141. The separate timing belt clamps 141 facilitate quick and easy assembly or disassembly of the slide 140 and the timing belt.

[0033] Anti-collision pads 112 are provided at both ends of the base 110 along its length. The anti-collision pads 112 are made of damping material. By providing anti-collision pads 112, the slide 140 can avoid rigid contact with the base 110 due to inertia in extreme situations such as sudden power failure when it is running, thus improving the safety performance of the linear slide 100.

[0034] The slide 140 includes a base 142 and a cover plate 143 located above the base 142. A channel 144 exists between the cover plate 143 and the base 142. The width of the cover plate 143 is greater than or equal to the width of the base 110. The slide 140 also includes a dustproof steel strip 145, which is connected to both ends of the base 110 and passes through the channel 144. The dustproof steel strip 145, connected to both ends of the base 110 and passing through the channel 144 between the base 142 and the cover plate 143, effectively prevents dust, debris, and other impurities from entering the linear slide 100, protecting key components such as the guide rail 120 and the slider 150 from contamination, reducing wear, and extending service life.

[0035] Furthermore, the linear slide 100 also includes a limiting component 170, which includes a limiting photoelectric sensor 171 and a light-shielding plate 172. The limiting photoelectric sensor 171 is installed on one side of the base 110, and is located near both ends of the base 110 along its length. The light-shielding plate 172 is fixedly connected to the slide 140. When the light-shielding plate 172 slides into the limiting photoelectric sensor 171, the slide 140 stops sliding. By using the limiting component 170, the slide 140 will stop sliding in a controlled manner when it reaches the designated position, effectively improving the safety performance of the linear slide 100.

[0036] In summary, in the linear slide table 100 of this utility model, the guide rail 120 is located at the center line of the base 110 along its length. This symmetrical layout helps the slide 140 maintain linear motion during movement, avoiding offset caused by structural asymmetry and ensuring the accuracy of movement. At the same time, by setting the guide rail 120 at the center line of the base 110 along its length and the slider 150 directly below the slide 140, the linear slide table 100 can maintain a relatively small width, which can adapt to the installation requirements of some equipment with limited space. Alternatively, while keeping the dimensions of the base 110 unchanged, the slide 140 can be made wider, enhancing the rigidity of the entire slide 140 and enabling it to remain stable under load, reducing bending and twisting, thereby improving load capacity. The fit between the mounting groove 151 and the protrusion 121 on the slider 150 makes the installation of the slider 150 and the guide rail 120 simpler and faster. Simply insert the slider 150 into the guide rail 120 and ensure that the protrusion 121 enters the insertion groove 1513. There is no need for complicated alignment and fixing procedures. At the same time, the design of the arc-shaped part 1514 can reduce stress concentration and reduce fatigue damage caused by excessive local stress, thereby improving the reliability and durability of the slide block 140.

[0037] Similarly, it should be noted that although the present invention has been described with reference to the specific embodiments described above, those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and various equivalent changes or substitutions can be made without departing from the spirit of the present invention.
