Description

Technical Field

[0001] This application relates to the field of linear module technology, and more specifically, to a dual-motor four-movement sub-module. Background Technology

[0002] In the field of automated precision equipment, such as semiconductor packaging, LCD panel handling, and precision testing, linear modules are core components for achieving efficient material handling. To improve production efficiency, multi-movement independent motion technology has become an industry trend.

[0003] The current mainstream solution adopts a single-motor driven long synchronous belt structure: a single motor is installed on the module base to drive a closed synchronous belt running through the entire length of the module, and multiple movers are fixed on the synchronous belt. This structure can realize the synchronous movement of multiple movers along a linear track, which is suitable for parallel handling or inspection tasks. However, this technology has significant drawbacks: all movers are driven by the same motor and must maintain the same direction and speed of movement, and cannot be independently controlled. When the process requires two movers to carry workpieces to perform actions of moving closer or further apart, such as precision alignment or separate handling, the single-motor module cannot meet the requirements, forcing the use of two independent modules arranged in parallel. The dual-module solution leads to a doubling of equipment costs, an increase in space occupation, and the need for complex synchronous control, resulting in a decrease in system reliability. Utility Model Content

[0004] To address the issues of increased cost, larger space requirements, and decreased system reliability caused by using two independent modules arranged in parallel when the process requires two movers to carry workpieces to perform actions that move towards or away from each other, this application provides a dual-motor four-motor module.

[0005] A dual-motor four-movement module includes a module base, two synchronous belts arranged in parallel on the module base, and two motor sets that drive the two synchronous belts respectively. Each synchronous belt is connected to two movers.

[0006] Preferably, it also includes two slide rails arranged in parallel on the module base, each slide rail having four sliders slidably disposed thereon, the four sliders on one slide rail corresponding one-to-one with the four sliders on the other slide rail, and the two corresponding sliders being connected to the same mover.

[0007] Preferably, the motor assembly includes a servo motor, a driving pulley, a driven pulley, a linkage pulley, and a transmission belt. The driving pulley and the driven pulley are rotatably mounted at both ends of the module base. The synchronous belt is sleeved on the driving pulley and the driven pulley. The linkage pulley is coaxially connected to the driving pulley. The servo motor is fixed on the module base, and a drive pulley is provided on the drive shaft of the servo motor. The transmission belt is sleeved on the linkage pulley and the drive pulley.

[0008] Preferably, the module base includes a front housing, a rear housing, and a middle rod. The middle rod is hollow and has a slot at its top that communicates with its interior. The slot passes through both ends of the middle rod. The front housing is fixed to one end of the middle rod and communicates with the interior of the middle rod. The rear housing is fixed to the other end of the middle rod and communicates with the middle rod. One set of motor sets has its drive wheel rotatably disposed in the front housing, and its servo motor is fixed outside the front housing. The set of motor sets' drive pulleys is located outside the front housing. The driven wheel of this set of motor sets is rotatably disposed in the rear housing. Another set of motor sets has its driven wheel rotatably disposed in the front housing. The drive wheel of this set of motor sets is disposed in the rear housing, and its servo motor is located outside the rear housing. The set of motor sets' drive pulleys is located outside the rear housing.

[0009] Preferably, the module base further includes a front steel strip clamping plate, a rear steel strip clamping plate, and a steel strip. The front steel strip clamping plate is disposed on the side where the front housing is connected to the intermediate rod, and the rear steel strip clamping plate is disposed on the side where the rear housing is connected to the intermediate rod. One end of the steel strip is fixedly connected to the front steel strip clamping plate, and the other end of the steel strip is fixedly connected to the rear steel strip clamping plate. Each of the four moving parts is provided with a through groove. The size of the through groove is adapted to the size of the steel strip so that the steel strip can pass through, and the steel strip abuts against the upper side of the through groove.

[0010] Preferably, the front housing and the rear housing are each provided with two parallel anti-collision screws on the side where they connect to the intermediate rod.

[0011] The beneficial technical effects of this application are as follows:

[0012] By configuring two independently driven synchronous belts and two motor sets, the four movers can be controlled independently in two groups. Compared with traditional single-motor modules, the two groups of movers can move synchronously in opposite directions, meeting the process requirements of precision alignment, separation and handling, etc., which require bidirectional coordination. Different groups of movers can run at different speeds, adapting to asynchronous processing scenarios of multiple workpieces, improving the flexibility of the production line. The single module integrates a dual-drive system, reducing the redundant configuration of the base, slide rail, and control module, thereby reducing costs. The dual motors and dual synchronous belts are integrated in the same module base, reducing the size of the equipment and saving equipment layout space. Attached Figure Description

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Reference Figure 1 and Figure 2 A dual-motor four-moving-subject module includes a module base 1, two synchronous belts 2 arranged in parallel on the module base 1, and two motor sets 3 that drive the two synchronous belts 2 respectively. Two moving parts 4 are fixedly connected to the surface of each synchronous belt 2, so that the module integrates a total of four moving parts 4. Two slide rails 5 are provided on the module base 1, and the two slide rails 5 are arranged in parallel. Each slide rail 5 has four sliders 6 slidably arranged on it, and the sliders 6 of the two slide rails 5 are in a one-to-one correspondence. Each moving part 4 is rigidly connected to the two sliders 6 at the corresponding position. The moving part 4 is supported by the slide rails 5 to make its movement stable.

[0020] Reference Figure 1 and Figure 3Each motor group 3 includes a servo motor 31, a drive pulley 32, a driven pulley 33, a linkage pulley 34, and a transmission belt 35. The drive pulley 32 and the driven pulley 33 are rotatably mounted at both ends of the module base 1, and the synchronous belt 2 is sleeved between them to form a closed-loop transmission. The linkage pulley 34 is coaxially fixed to the drive pulley 32. The servo motor 31 is fixed on the module base 1, and its drive shaft is equipped with a drive pulley 311. The transmission belt 35 is sleeved on the drive pulley 311 and the linkage pulley 34, thereby transmitting the power of the servo motor 31 to the drive pulley 32 and driving the synchronous belt 2 to circulate.

[0021] Reference Figure 1 and Figure 2 Furthermore, the module base 1 adopts a split design, including a front housing 11, a rear housing 12, and a middle rod 13. The middle rod 13 is hollow, and its top has a long strip slot 131 that runs through both ends, allowing the interior of the middle rod 13 to communicate with the exterior. A slide rail 5 is located at the bottom of the middle rod 13. The front housing 11 and the rear housing 12 are respectively fixed to both ends of the middle rod 13, and both are connected to the internal cavity of the middle rod 13. The two sets of motor groups 3 adopt a cross layout to save space. Specifically, the driving pulley 32 of the first set of motor groups 3 is installed inside the front housing 11, and its linkage pulley 34 is exposed on the outside of the front housing 11. The servo motor 31 is fixed to the outer wall of the front housing 11 and connected to the linkage pulley 34 through a transmission belt 35. The driven pulley 33 of this set is installed inside the rear housing 12. The driving pulley 32 of the second motor group 3 is installed inside the rear housing 12, and its linkage pulley 34 is located outside the rear housing 12. The servo motor 31 is fixed to the outer wall of the rear housing 12 and driven by the transmission belt 35. The driven pulley 33 of this group is installed inside the front housing 11. This layout allows the two synchronous belts 2 to run independently through the slot 131 of the intermediate rod 13.

[0022] Reference Figure 1 and Figure 2 Furthermore, to enhance the anti-overturning capability of the mover 4, the module base 1 also includes a front steel strip clamp 14, a rear steel strip clamp 15, and a steel strip 16. The front steel strip clamp 14 is fixed to the side of the front housing 11 connecting to the intermediate rod 13, and the rear steel strip clamp 15 is fixed to the corresponding side of the rear housing 12. The two ends of the high-strength steel strip 16 are respectively locked to the front steel strip clamp 14 and the rear steel strip clamp 15 with bolts. Each of the four movers 4 has a rectangular through-slot 41 with a size matching the steel strip 16 at its bottom. The steel strip 16 passes horizontally through all the through-slots 41 of the movers 4, and the upper inner wall of the through-slot 41 abuts against the upper surface of the steel strip 16, forming a vertical mechanical limit to prevent the movers 4 from swaying during high-speed movement.

[0023] Reference Figure 2Two parallel anti-collision screws 17 are installed on the sides of the front housing 11 and the rear housing 12 facing the middle rod 13 to absorb the impact energy when the mover 4 moves to the limit position and avoid hard collision damage to precision parts.

[0024] The implementation principle of the dual-motor four-moving-sub-module of this application is as follows: two synchronous belts 2 are independently controlled by two servo motors 31, so that the four moving parts 4 are divided into two groups, with two moving parts 4 in each group. The first group of moving parts 4 is driven by the first synchronous belt 2, and the second group is driven by the second synchronous belt 2. The two groups can move in the same direction and at the same speed, or they can move towards each other, away from each other, or move asynchronously at different speeds to meet the collaborative needs of complex processes. The module base 1 integrates a dual-drive system, avoiding the redundant structure of traditional parallel dual-module modules, significantly reducing manufacturing costs and space occupation. At the same time, the connection between the slide rail 5 and the double slider 6 and the limiting design of the steel belt 16 ensure high-precision motion stability.
