[0002] Currently, linear modules are being used more and more widely. Many fully enclosed linear modules are prone to overheating during operation, which affects their service life. On the other hand, many open linear modules tend to have more dust.

[0003] In addition, when there is an application requirement for long-distance gliding, the slide in the existing linear module is prone to shaking and uneven sliding, which will affect the user experience of the product.

[0004] In view of this, it is indeed necessary to provide a linear module to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a linear module with good heat dissipation, good dust resistance, and smooth sliding.

[0006] To achieve the above objectives, this utility model provides a linear module, comprising a base and a slide block, the slide block being slidably connected to the base. The slide block includes a main body and a top block located above the main body. The width of the top block is greater than the width of the main body. A passage is provided in the top block. A cover plate is provided on the base, the cover plate passing through the passage block. A gap exists between the cover plate and the base. The top block includes a top plate and side plates extending from both sides of the top plate toward the base. A slot is provided between the side plates and the base. The base includes a bottom plate and a side wall extending from the bottom plate toward the top block. A retaining strip extends from the inner side of the side wall toward the top block, and the retaining strip is inserted into the slot.

[0007] As a further improvement of this utility model, the linear module further includes a drive motor and a transmission assembly. The drive motor is installed at one end of the base, and the transmission assembly includes a lead screw and a nut. The lead screw passes through the slide block, one end of the lead screw is connected to the output shaft of the drive motor, and the other end is connected to the slide block. The nut is sleeved on the lead screw and is fixedly connected to the slide block. The lead screw rotates to drive the nut to drive the slide block to slide along the axial direction of the lead screw.

[0008] As a further improvement of this utility model, the slide includes a first end and a second end, the first end being closer to the drive motor than the second end, the main body having a through hole, the lead screw passing through the through hole, a bushing being provided in the through hole at the first end, and the nut being inserted into the through hole from the second end.

[0009] As a further improvement of this utility model, the through hole includes a head space near the first end and a tail space near the second end, as well as a middle space located between the head space and the tail space. The inner diameters of the head space and the tail space are both larger than the middle space. The bushing is placed in the head space, and the nut portion is placed in the tail space.

[0010] As a further improvement of this utility model, the lead screw includes a head section near the drive motor and a tail section away from the drive motor.

[0013] As a further improvement of this utility model, the linear module also includes a limiting component, which includes a photoelectric sensor and a limiting photoelectric sensor. The two limiting photoelectric sensors are respectively arranged near the two ends of the base in the length direction. The photoelectric sensor is fixedly connected to the slide block. The photoelectric sensor and the limiting photoelectric sensor are located on the same side of the linear module. When the photoelectric sensor slides into the limiting photoelectric sensor, the slide block stops sliding.

[0014] In summary, the linear module of this utility model has a top mount that is wider than the main body, providing more operating space for installation and adjustment. This facilitates the installation, disassembly, and maintenance of components on the top mount by workers, and also allows for fine-tuning of the slide position to meet the precise installation requirements of different application scenarios. The combination of the slot and the locking strip ensures that the slide will not easily shift or wobble when sliding along the base, making installation and disassembly more convenient and quick, without the need for complicated tools and cumbersome steps, thus improving the efficiency of installation and maintenance.

[0028] The following detailed description of the features and advantages of this utility model is sufficient to enable those skilled in the art to understand the technical content of this utility model and implement it accordingly. Furthermore, based on this specification, claims, and drawings, those skilled in the art can easily understand the related objectives and advantages of this utility model.

[0029] The terminology and expressions used herein are for descriptive purposes only, and this invention should not be limited to these terms and expressions. The use of these terms and expressions does not mean the exclusion of any illustrative and descriptive equivalent features (or parts thereof), and it should be recognized that various modifications that may exist should also be included within the scope of the claims. Other modifications, variations, and substitutions may also exist. Accordingly, the claims should be considered to cover all such equivalents.

[0030] Please see Figures 1-7 As shown, a linear module 100 provided by this utility model includes a base 300 and a slide 200. The slide 200 is slidably connected to the base 300. The slide 200 includes a main body 210 and a top seat 220 located above the main body 210. The width of the top seat 220 is greater than the width of the main body 210. A passage 221 is provided in the top seat 220. A cover plate 130 is covered on the base 300. The cover plate 130 passes through the slide 200 from the passage 221. There is a gap between 130 and base 300. Top seat 220 includes top plate 222 and side plates 223 extending from both sides of top plate 222 toward base 300. A slot 224 is provided between side plate 223 and base 300. Base 300 includes bottom plate 310 and side wall 320 extending from bottom plate 310 toward top seat 220. A retaining strip 330 extends from the inner side of side wall 320 toward top seat 220 and is inserted into slot 224.

[0031] The cover plate 130 covers the base 300 and passes through the slide 200 from the passage 221. It can block external impurities, dust, liquids and other substances from entering the interior of the linear module 100 to a certain extent, thus protecting key components such as the lead screw 410 inside. This reduces wear and failure of components caused by external factors and improves the service life and reliability of the module. The gap between the cover plate 130 and the base 300 gives the linear module 100 good air permeability. During maintenance, the condition of each component inside the linear module 100 can be better observed without removing the cover plate 130.

[0032] Meanwhile, the width of the top mount 220 is greater than the width of the main body, providing more operating space for installation and adjustment. This makes it easier for staff to install, disassemble, and maintain the components on the top mount 220. It also facilitates fine-tuning of the position of the slide 200 to meet the precise installation requirements of different application scenarios. The way the slot 224 and the clip 330 cooperate ensures that the slide 200 will not easily shift or shake when sliding along the base 300, making installation and disassembly more convenient and quick. It does not require complicated tools and tedious steps, thus improving the efficiency of installation and maintenance.

[0033] Furthermore, in this embodiment, the linear module 100 also includes a drive motor 120 and a transmission assembly 400. The drive motor 120 is mounted on one end of the base 300. The transmission assembly 400 includes a lead screw 410 and a nut 420. The lead screw 410 passes through the slide 200. One end of the lead screw 410 is connected to the output shaft of the drive motor 120, and the other end is connected to the slide 200. The nut 420 is sleeved on the lead screw 410 and is fixedly connected to the slide 200. The rotation of the lead screw 410 drives the nut 420 to slide the slide 200 along the axial direction of the lead screw 410. By driving the lead screw 410 to rotate through the drive motor 120, the nut 420 moves precisely along the axial direction of the lead screw 410, thereby driving the slide 200 to achieve precise linear motion. This transmission method can achieve high positional accuracy and is suitable for automated production lines with strict positioning accuracy requirements, such as semiconductor manufacturing and electronic chip packaging, ensuring the accuracy of product processing and assembly.

[0034] Furthermore, in this embodiment, the slide 200 includes a first end and a second end. The first end is closer to the drive motor 120 than the second end. The main body 210 is provided with a through hole 211 through which the lead screw 410 passes. A bushing 230 is provided in the through hole 211 at the first end. The nut 420 is partially inserted into the through hole 211 from the second end.

[0035] Furthermore, in this embodiment, the through hole 211 includes a head space 2111 near the first end and a tail space 2112 near the second end, as well as a middle space 2113 located between the head space 2111 and the tail space 2112. The inner diameters of both the head space 2111 and the tail space 2112 are larger than the middle space 2113. The bushing 230 is placed in the head space 2111, and the nut 420 is partially placed in the tail space 2112. The through hole 211 is divided into a head space 2111, a middle space 2113, and a tail space 2112, and the inner diameters of the head space 2111 and the tail space 2112 are larger than the middle space 2113. This structure provides sufficient operating space for the installation of the bushing 230 and the nut 420. The bushing 230 can be smoothly placed in the head space 2111, and the nut 420 can easily reach the tail space 2112 after being inserted from the first end. When the bushing 230 or nut 420 needs to be replaced due to wear or damage, the larger head space 2111 and tail space 2112 facilitate tool operation and component removal and installation. Maintenance personnel can quickly maintain or replace these critical components, reducing equipment downtime for maintenance and improving equipment utilization. The larger head space 2111 and tail space 2112 can, to a certain extent, disperse the stress generated by the lead screw 410 and nut 420 during transmission, avoiding excessive stress concentration that could lead to component fatigue damage, extending component service life, and enhancing the reliability and durability of the linear module 100.

[0036] Furthermore, the lead screw 410 includes a head section 411 near the drive motor 120 and a tail section 412 away from the drive motor 120. The head section 411 includes a first part 4111 and a second part 4112. The first part 4111 is closer to the drive motor 120 than the second part 4112. A middle section 413 is provided between the second part 4112 and the tail section 412. The diameter of the tail section 412 is smaller than the diameter of the middle section 413. The diameter of the first part 4111 is smaller than the diameter of the second part 4112, and the diameter of the second part 4112 is smaller than the diameter of the middle section 413. The transmission assembly 400 also includes a coupling 430, with the first part 4111 and the output shaft of the drive motor 120 respectively inserted into both ends of the coupling 430.

[0037] A first bearing 340 is embedded at the end of the base 300 facing the drive motor 120 and is sleeved on the second part 4112. A second bearing 350 is embedded at the end of the base 300 facing away from the drive motor 120 and is sleeved on the tail section 412.

[0038] By inserting the first part 4111 and the output shaft of the drive motor 120 into both ends of the coupling 430, this design achieves a coaxial connection between the lead screw 410 and the drive motor 120, ensuring the accuracy of power transmission, reducing vibration and impact caused by misalignment, and improving the stability and precision of the transmission system. The base 300 has a first bearing 340 and a second bearing 350 embedded at both ends, respectively, fitted onto the second part 4112 and the tail section 412 of the lead screw 410, forming multi-point support for the lead screw 410. This makes the force on the lead screw 410 more even during rotation, reducing bending deformation and vibration, and improving the rotational accuracy and stability of the lead screw 410. Especially under high-speed operation or heavy loads, it effectively ensures the normal operation of the lead screw 410. The second part 4112 has a larger diameter, which, in conjunction with the first bearing 340, allows it to withstand larger radial and axial loads. Through reasonable support and connection design, the stress and wear of each part of the lead screw 410 are reduced, and fatigue damage caused by local stress concentration or excessive friction is reduced, thereby improving the service life of the lead screw 410 and reducing the maintenance frequency and replacement cost of the equipment.

[0039] In this embodiment, the linear module 100 further includes a limiting component 110, which includes a photoelectric sensor 111 and a limiting photoelectric sensor 112. The two limiting photoelectric sensors 112 are respectively disposed near both ends of the base 300 along its length. The photoelectric sensor 111 is fixedly connected to the slide 200, and the photoelectric sensor 111 and the limiting photoelectric sensor 112 are located on the same side of the linear module 100. When the photoelectric sensor 111 slides into the limiting photoelectric sensor 112, the slide 200 stops sliding. By using the limiting component 110, the slide 200 will stop sliding in a controlled manner when it reaches the designated position, effectively improving the safety performance of the linear slide. At the same time, through reasonable support and connection design, the stress and wear on various parts of the lead screw 410 are reduced, and fatigue damage caused by local stress concentration or excessive friction is reduced, thereby increasing the service life of the lead screw 410 and reducing the maintenance frequency and replacement cost of the equipment.

[0040] In summary, in the linear module 100 of this utility model, the width of the top seat 220 is greater than the width of the main body, providing more operating space for installation and adjustment. This facilitates the installation, disassembly, and maintenance of the components on the top seat 220 by the staff, and also makes it easier to fine-tune the position of the slide 200 to meet the precise installation requirements in different application scenarios. The cooperation between the slot 224 and the clip 330 ensures that the slide 200 will not easily shift or shake when sliding along the base 300, making installation and disassembly more convenient and quick, without the need for complicated tools and cumbersome steps, thus improving the efficiency of installation and maintenance.

[0041] 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. Therefore, any changes or modifications to the above embodiments within the scope of the essential spirit of the present invention will fall within the scope of the claims of the present invention.
