Description

Technical Field

[0001] This utility model relates to the field of variable pitch module technology, and in particular to a wafer-specific variable pitch module. Background Technology

[0002] Modular design is an important trend in modern industrial design, aiming to improve design efficiency and product quality while reducing costs and risks. Variable pitch modules, as a key technology in modular design, possess high flexibility and intelligence.

[0003] Most of the variable pitch modules on the market are cam variable pitch modules, which mainly rely on the rotation of the camshaft to achieve constant pitch mechanism. It is a mechanism that changes the distance of the slide carried on the roller by machining spiral guide grooves on the roller. Therefore, when the number of slides increases, the number of guide grooves on the roller also increases. Too many guide grooves will cause the walls between adjacent guide grooves to be too thin, or even cause the guide grooves to intersect.

[0004] For the reasons mentioned above, it is necessary to improve the existing technology. Utility Model Content

[0005] I. Technical problems to be solved This utility model addresses the aforementioned deficiencies in the existing technology by proposing a wafer-specific variable pitch module to solve the problems mentioned in the background art.

Technical Solution To solve the above-mentioned technical problems, this utility model provides a wafer-specific pitch module, including a housing, and a driving device is provided at one end of the housing; It also includes two rotating rollers, which are arranged in parallel within the inner cavity of the housing. The two ends of the rotating rollers are rotatably supported at both ends of the housing. The rotating rollers are provided with multiple guide grooves, and the guide grooves of the two rotating rollers are staggered. The ends of the rotating rollers are provided with a transmission device connected to the driving device. A slide block assembly includes a slide block movably disposed in the housing, a support frame disposed on both sides of the slide block, and a slider disposed on the side of the support frame. The number of slide blocks is the same as the number of guide grooves. The end of the slider slides in sliding engagement with the housing, and adjacent sliders are staggered. The bottom end of the slide block is provided with a guide block that engages with the guide groove.

[0007] In the above technical solution, a first mounting plate and a second mounting plate are fixedly arranged on the left and right sides of the housing, respectively, and a third mounting plate is fixedly arranged between the rotating rollers. The third mounting plate extends longitudinally to the same height as the first mounting plate and the second mounting plate. Guide rails extending along the axial direction of the rotating rollers are fixedly arranged on the first mounting plate, the second mounting plate and the third mounting plate, and the guide rails and the slider are used in cooperation.

[0008] In the above technical solution, the transmission device includes a driving wheel disposed at the end of the driving device, a driven wheel disposed at the end of the rotating roller, and a transmission belt connecting the driving wheel and the driven wheel.

[0009] In the above technical solution, multiple position sensors are spaced apart on the side of the second mounting plate, and a sensing strip that works in conjunction with the position sensors is fixedly installed on one side of the outermost slide.

[0010] In the above technical solution, the driving device is a drive motor.

[0011] III.

Detailed Implementation

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0021] Please see Figure 1-7 This utility model provides a wafer-specific variable pitch module, including a housing 1, and a driving device 10 is provided at one end of the housing 1; It also includes two rotating rollers 2, which are arranged in parallel in the inner cavity of the housing 1. The two ends of the rotating rollers 2 are rotatably supported at the two ends of the housing 1. The rotating rollers 2 are provided with multiple guide grooves 20, and the guide grooves 20 of the two rotating rollers 2 are staggered. The end of the rotating rollers 2 is provided with a transmission device 11 connected to the driving device 10. The slide assembly 3 includes a slide 30 movably disposed in the housing 1, a support frame 31 disposed on both sides of the slide 30, and a slider 32 disposed on the side of the support frame 31. The number of slides 30 is the same as the number of guide grooves 20. The end of the slider 32 is slidably engaged with the housing 1, and adjacent sliders 32 are staggered. The bottom end of the slide 30 is provided with a guide block 33 that engages with the guide groove 20.

[0022] In the above structure, the variable pitch module housing is provided with two parallel rotating rollers. The ends of the rotating rollers are rotatably supported at both ends of the housing. There is a phase difference between the two rotating rollers, which causes the guide grooves on the two rotating rollers to be staggered. Each slide has a guide block at the bottom that cooperates with a guide groove, which causes the slides on the two rotating rollers to be staggered with each other, thereby increasing the number of workstations of the variable pitch module. At the same time, the sliders of adjacent slides on a single rotating roller are staggered, which allows more workstations to be placed in the variable pitch module housing in the same space. Without changing the space occupied by the variable pitch module, the number of workstations of the variable pitch module is increased.

[0023] Specifically, a first mounting plate 12 and a second mounting plate 13 are fixedly disposed on the left and right sides of the housing 1, respectively, and a third mounting plate 14 is fixedly disposed between the rotating rollers 2. The third mounting plate 14 extends longitudinally to the same height as the first mounting plate 12 and the second mounting plate 13. Guide rails 100 extending along the axial direction of the rotating rollers 2 are fixedly disposed on the first mounting plate 12, the second mounting plate 13 and the third mounting plate 14. The guide rails 100 and the slider 32 are used in cooperation. The cooperation between the guide rails and the slider can reduce the coefficient of friction of the slide during the sliding process, thereby saving energy.

[0024] Specifically, the transmission device 11 includes a drive wheel 110 disposed at the end of the drive device 10, a driven wheel 111 disposed at the end of the roller 2, and a transmission belt 112 connecting the drive wheel 110 and the driven wheel 111. The belt drive composed of the transmission belt, driven wheel and drive wheel can absorb vibration and impact during operation due to the elastic buffering characteristics of the transmission belt, thereby reducing instability during operation and reducing the operating noise of the transmission equipment.

[0025] Specifically, the second mounting plate 13 is provided with multiple position sensors 130 at intervals on its side. The outermost slide 30 is fixedly provided with a sensing strip 300 that works in conjunction with the position sensor 12. The position sensor and the sensing strip work together to record the position of the outermost slide. When the variable pitch module is shut down and restarted due to a sudden problem such as power failure, the slide can be returned to its initial position by the cooperation of the position sensor and the sensing strip.

[0026] Specifically, the drive device 10 is a drive motor. Using a drive motor as the drive device has advantages such as high efficiency and energy saving, high reliability, and small space occupation.

[0027] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
