Description

Technical Field

[0001] The invention belongs to the technical field of processing and transmission devices, and in particular relates to a double-axis conveying type circulating processing and transmission device. Background Art

[0002] In automated production lines, station circular motion production lines are widely used, and the application requirements are becoming more and more complex and varied. There are four commonly used traditional multi-station circular production lines.

[0003] The first type is driven by a rotary servo motor with a synchronous belt or sprocket. The same synchronous belt or sprocket connects multiple workstation fixture carriers at different workstations to achieve cyclic movement. This structure has low positioning accuracy, and each workstation is not independent and cannot be moved individually, so diversion cannot be achieved.

[0004] The second type is driven by a linear motor, with a circular guide rail and a circular distribution of magnets. The mover provides power for the corresponding workstation fixture carrier. By individually controlling each mover, the workstation fixture carrier can move cyclically with the circular guide rail. Although this structure can achieve independent control of each workstation, the cable connection is complicated and is constrained by the connecting cables. Each workstation cannot be separated from the circular line where it is located and cannot be diverted, making it difficult to freely splice and adapt to the construction of diversified production lines.

[0005] The third type is the dynamic magnet linear motor circular line, which is also used by a linear motor in conjunction with a circular guide rail. The difference is that each workstation fixture carrier is equipped with a linear motor magnetic rail. The linear motor coil is fixed, and the coil is energized to generate a magnetic field that drives the linear motor magnet, thereby driving the workstation fixture carrier to move. The advantage of this type of circular line is that the cables can be fixed, and the workstation fixture carrier has no cables to follow, so it can be diverted at will, but the coils need to be distributed throughout the entire circular production line, and the position feedback deviation of the splicing points needs to be solved. The program control is complex, the customization cost is high, and the price is expensive.

[0006] The fourth type is a relay-transfer circulating production line. The circulating moving track and power source of the workstation fixture carrier are divided into two layers. The workstation fixture carrier runs on the upper circulatory production track. There are multiple sets of linear modules in the lower layer that are coupled with the corresponding workstation fixture carrier through the traction mechanism, and drive the workstation fixture carrier to move to the next station. Then the traction mechanism is separated from the carrier and returns to the previous station. This cycle is repeated to continuously transport the carrier from one station to the next. This type of circulating production line is used in conjunction with a linear motor multi-mover module. Each mover only needs to travel back and forth between two stations. The control is simpler, and each mover is controlled separately, which is more flexible. The economy is better than the moving magnetic circulating line, and the flexibility and positioning accuracy are better than the synchronous belt or sprocket circulating line. It can also achieve diversion and convergence according to the needs of the production line.

[0007] The existing relay-transmission circulating production lines all adopt single-axis drive. The driving motor of the single-axis drive structure will have a time gap during the resetting process, and cannot achieve continuous and uninterrupted drive, resulting in low production efficiency. At the same time, the single-axis drive structure of the existing relay-transmission circulating production line, in order to achieve structural balance, its drive module is all set inside the device, which is not convenient for internal fault detection, parts replacement and maintenance. Summary of the invention

[0008] In order to solve the above problems, the primary purpose of the present invention is to provide a dual-axis conveying type circulating processing transmission device, which can effectively improve production efficiency by coordinating and staggering the linear motor drive mechanisms on both sides without interfering with each other;

[0009] Another object of the present invention is to provide a dual-axis conveying type circulating processing transmission device, which can facilitate the troubleshooting of internal faults of the linear motor drive mechanisms on both sides, the replacement of parts, and convenient maintenance;

[0010] The last object of the present invention is to provide a dual-axis conveying type circulating processing transmission device with simple structure, low cost, and easy promotion and use.

[0011] To achieve the above object, the technical solution of the present invention is as follows:

[0012] The present invention provides a dual-axis conveying type circulating processing and transmission device, comprising a base, wherein symmetrical linear motor drive mechanisms are arranged on the left and right sides of the base, wherein the linear motor drive mechanism comprises a magnetic rail and several linear motor drive components, wherein several linear motor drive components share one magnetic rail, and a product carrier guide mechanism is also arranged above the base, wherein the product carrier guide mechanism comprises a product carrier guide rail and several product carriers, wherein the product carrier is slidably connected to the product carrier guide rail, and a lifting component is installed on the linear motor drive component, wherein the lifting component can be coupled with and separated from the product carrier by moving up and down. In the present invention, linear motor drive mechanisms are arranged on both sides of the base, and several linear motor drive components of each linear motor drive mechanism share a magnetic track to form a coaxial multi-moving substructure. A lifting component is arranged on each linear motor drive component, and several linear motor drive components can be freely coupled and separated with several product carriers through their respective lifting components. When multiple workstation product carriers need to be transported, the lifting components connected to the linear motor drive components on one side can be moved upward to be coupled with the product carriers at each workstation respectively, and the product carrier is pulled from workstation one to workstation two, and then detached; the lifting components connected to the linear motor drive components on the other side can be moved upward to be coupled with the product carriers at each workstation respectively, and the product carrier is pulled from workstation two to workstation three. The linear motor drive mechanisms on both sides convey the product carriers in an alternating manner, which makes full use of the motor reset time and is more efficient; and the linear motor drive components on both sides move in separate axes to avoid position interference and reduce the possibility of collision. In addition, through this relay-type transmission, the product carrier sent out from the workstation has no connection with this special module and can be diverted at will. The product carrier to be moved in can also come from different conveying routes and can be converged at will without interfering with each other, thereby increasing the stability of the module's operation.

The linear motor is arranged on both sides of the base, which is convenient for troubleshooting the internal faults of the motor, replacing parts, and maintaining more conveniently; compared with the dynamic magnetic multi-station circulation platform in the prior art, the control of the module is simpler, the construction is more convenient, and the maintenance is easy, which is suitable for various complex production lines and has a wider application field.

[0014] Furthermore, the cavity is a trough structure with a C-shaped cross section. In the present invention, the linear motor drive mechanism providing power is arranged on the inner side wall of the cavity of the C-shaped structure, making full use of the internal space of the module body, with a compact layout and small space occupation.

In the present invention, when the product carrier moves to the work station, the lifting cylinder drives the lifting pin block to descend, and the wedge-shaped movable block moves down to engage with the corresponding wedge-shaped fixed block at the work station to achieve position locking; when the product carrier needs to be moved, the lifting cylinder drives the lifting pin block to rise, and lifts the wedge-shaped movable block to move up to separate from the corresponding wedge-shaped fixed block at the work station, thereby releasing the position of the product carrier.

[0017] Furthermore, the linear motor drive assembly includes a mover and a sliding plate, the mover is fixedly connected to the sliding plate, the magnetic rail is installed on the side wall of the connecting plate, the movers of several linear motor drive assemblies match and share the magnetic rail, the upper and lower parts of the cavity are provided with symmetrical rails, the rails in the upper part of the cavity are embedded in the upper support plate, and the rails in the lower part of the cavity are embedded in the lower support plate, and linear sliders are provided on the upper and lower sides of the sliding plate, and the linear sliders are slidably connected to the rails.
