Description

Technical Field

[0001] The invention relates to the technical field of slide modules, in particular to a screw-driven bidirectional motion linear slide module. Background Art

[0002] As modern industrial production develops towards refinement and intelligence, in many fields such as semiconductor manufacturing, precision instrument processing, and medical device production, the requirements for the linear motion accuracy of equipment parts are getting higher and higher. For example, in the process of semiconductor chip manufacturing, wafer lithography, etching and other processes require extremely precise linear motion to ensure the process accuracy of the chip. The lead screw linear slide can meet this micron-level or even higher precision positioning needs.

[0003] The existing linear slide module still has the following technical problems when in use, such as:

[0004] 1. The existing linear slide module needs to use a dustproof structure when in use. The dustproof structure mainly includes rubber, soft plastic, stainless steel belt, accordion cover and felt. When the stainless steel belt is used for dustproof, screws are generally used to fix the stainless steel belt to the slide module. As the slide module is used for a longer time, the connection of the stainless steel belt will become loose, which will reduce the sealing effect and cause the dust generated during the operation of the slide module to fall into the interior of the slide module.

[0005] 2. When the existing linear slide module is in use, the two ends of the slide module are connected by screws and dustproof structures, so the connection stability of the two ends of the slide module can be improved. However, the shell of the slide module is mainly composed of the structures at both ends and the structure in the middle, so only improving the connection stability of the structures at both ends is not beneficial to the stability of the entire shell;

[0006] Therefore, a screw-driven bidirectional motion linear slide module is needed to solve the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide a screw-driven bidirectional motion linear slide module to solve the problems raised in the above background technology that the sealing effect of the dustproof structure of the existing linear slide module will decrease with the increase of usage time and the overall connection stability of the shell cannot be improved.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: the screw-driven bidirectional motion linear slide module can prevent the sealing between the two ends of the dust-proof belt and the support end seat and the support shell from being reduced by the mutual limitation between the structures, thereby ensuring the sealing effect. In addition, the mutual limitation between the structures can also improve the structural stability of the whole structure formed by the support end seat and the support shell:

[0020] 1. The right-angle teeth between the limiter and the sealing end can be meshed by the second spring, so that the sealing end can be limited to prevent it from falling out of the vertical groove. At the same time, the vertical groove squeezes the pressure-bearing sheet, so that the engaging block and the connecting block can be kept in engagement and connection, and the right-angle teeth between the two can also be kept in engagement, so that the sealing end can only move upward. Since the vertical groove allows the sealing end to move only horizontally, it limits the movement of the sealing end in both the vertical and horizontal directions. Therefore, through two sets of right-angle teeth, the sealing ends at both ends of the dustproof belt can be stably connected to the support end seat and the support shell, avoiding the problem of reduced sealing effect due to the increase in the use time of the slide module;

[0021] 2. Through two sets of right-angle teeth, the sealing end can be connected to the support end seat and the support shell. Therefore, in addition to the snap-fit ​​connection between the embedded groove and the embedded block and the bolt connection between the two, the support end seat and the support shell are also connected through the sealing end, which helps to improve the overall structural stability of the support shell and the support end seat, and further improve the integrity of the slide module.

Both ends of the support shell 1 are connected to the support end seat 2 through the engagement of an embedding groove 6 and an embedding block 7, and the embedding groove 6 and the embedding block 7 are respectively arranged on the support shell 1 and the support end seat 2. A motor 3 is installed on one of the two support end seats 2, and the shaft end of the motor 3 is coaxially connected to one end of a screw 8. The other end bearing of the screw 8 penetrates the support end seat 2 on which the motor 3 is installed, and is connected to the bearing of the other support end seat 2. The screw 8 screw The groove runs through the lower end of the slide body 5, and the slide body 5 is movably penetrated by the dustproof belt 4. A sliding groove 9 is arranged on the upper surface of the support shell 1, and a supporting convex strip 10 is fixedly connected in the sliding groove 9.

The inner and outer sides of the sealing end 16 are provided with rubber sealing pads 17, and the lower surface of the dustproof belt 4 is also provided with a rubber sealing pad 17. The maximum distance between the rubber sealing pads 17 on the inner and outer sides of the sealing end 16 is greater than the inner width of the vertical groove 30, so that the vertical groove 30 can be completely blocked by the rubber sealing pads 17 on the inner and outer sides of the sealing end 16, which helps to improve the sealing performance of the connection between the sealing end 16 and the support end seat 2. The limiting mechanism includes a mounting groove 21 , a cross groove 23 and a limit piece 25, the installation groove 21 is provided on both the front and rear sides of each support end seat 2, and a toggle block 22 is slidably connected in the installation groove 21, the cross groove 23 is also provided on both the front and rear sides of each support end seat 2, and two cross grooves 23 are provided on the front and rear sides of each support end seat 2, the cross groove 23 runs through the outer side of the support end seat 2 and the vertical groove 30, the limit piece 25 is movably provided through the cross groove 23, and a spring 24 is provided between the limit piece 25 part in the cross groove 23 and the cross groove 23, the part of the limit piece 25 extending into the vertical groove 30 is connected to the side surface of the corresponding end of the sealing end 16 through the mutually meshing right-angle teeth, and the limit piece 25 is composed of 2 rod structures and 2 The plate structure is composed of two plate structures, which are fixedly connected to the two ends of the two rod structures respectively. The right-angle teeth are arranged on the plate structure in the vertical groove 30. The spring 24 in the cross groove 23 can ensure that the plate structure of the limiter 25 close to the sealing end 16 always has an extrusion force toward the sealing end 16, thereby ensuring that the sealing end 16 and the plate structure of the limiter 25 close to the sealing end 16 are always connected through the meshing between the right-angle teeth, thereby preventing the sealing end 16 from being withdrawn from the vertical groove 30. By preventing the sealing end 16 from being withdrawn from the vertical groove 30, the rubber sealing pad 17 can be ensured to be always in an extruded state, thereby ensuring the sealing effect, and preventing the sliding table module from being used for a long time, thereby preventing the dustproof structure from being reduced in sealing performance, thereby preventing it from being damaged. The dust effect is reduced, the mounting groove 21 is a transverse T-shaped structure, which is used to engage and slide with the sheet structures at the upper and lower ends of the toggle block 22, and the height of the mounting groove 21 is less than the shortest distance between the two rod structures, the toggle block 22 is a right-angled trapezoidal structure, and the two rod structures on the limiter 25 are symmetrical about the axial plane of the toggle block 22, the inclined surface of the toggle block 22 is arranged toward the limiter 25, and the maximum distance between the toggle block 22 and the side surface of the supporting end seat 2 connected to it is greater than the distance between the plate structure externally arranged on the limiter 25 and the side surface of the supporting end seat 2 in a natural state, so that when the toggle block 22 moves, the limiter 25 is pulled outward, so that the right-angle teeth engaged with the sealing end 16 are moved away from each other, and the limit of the sealing end 16 by the limiter 25 is released.

[0040] Embodiment 2: In order to solve the problem that the middle structure and the dustproof structure of the slide module are not connected tightly enough in the past, resulting in reduced sealing effect, the following technical solution is provided, specifically, the sealing mechanism is connected to the end of the support shell 1 through a pressing mechanism.

[0041] The pressing mechanism includes a transverse groove 12, a connecting block 13 and a snap-fit ​​block 14. The transverse groove 12 is arranged on the upper surface of the two ends of the supporting shell 1, and the position of the transverse groove 12 corresponds to the position of the end of the vertical groove 30. The snap-fit ​​block 14 is arranged on the side of each sealing end 16 facing the transverse groove 12, and the snap-fit ​​block 14 and the sealing end 16 are snap-fitted and slidably connected. The snap-fit ​​block 14 is provided with a symmetrical limiting hole 27, and the limiting hole 27 is extended into one end of a corresponding limiting rod 26. The other end of the limiting rod 26 movably penetrates the sealing end 16 and is connected to the pressure-bearing sheet 15, and the pressure-bearing sheet 15 is provided near the inner side of the vertical groove 30. A spring three 28 is arranged between the snap block 14 and the inner side surface of the sealing end 16 and is nested in the outer side of the limit rod two 26.

The material of the front and rear sections of the connecting block 13 is PA, and the right-angle teeth are distributed on the opposite sides of the front and rear sections of the connecting block 13. The thickness of the connecting block 13 is the same as the thickness of the sealing end 16, and the axial surface of the connecting block 13, the axial surface of the transverse groove 12 and the axial surface of the end of the sealing end 16 are coplanar, and the sealing end 16 is gradually engaged into the vertical groove 30. During the process, the pressure-bearing sheet 15 will be gradually squeezed, and then the pressure-bearing sheet 15 drives the limiting rod 26 to gradually extend into the inside of the limiting hole 27. During this process, the limiting rod 26 contacts the cross section of the limiting hole 27, driving the locking block 14 to move synchronously, and causing the spring 3 28 to be stretched. During the movement of the locking block 14, it is gradually locked between the front and rear sections of the connecting block 13, and through the elasticity of the PA structure, the right-angle teeth between the connecting block 13 and the locking block 14 are meshed. At this time, the sealing ends 16 at both ends of the dustproof belt 4 can be stably connected to the supporting shell 1, thereby avoiding the reduction of the sealing effect between the two.
