Description

Technical Field

[0001] The utility model relates to a conveying and positioning mechanism for a material tray, in particular to an adjustable material tray conveying mechanism. Background Art

[0002] Material trays, such as blister trays, are widely used across various industries, especially in the consumer electronics (3C) industry, where they serve as a key means of transporting and storing electronic components and parts. However, in traditional machines, material trays, such as these, are typically transported and positioned using conveyor belts and pneumatic cylinders. While this model achieves basic material transport and positioning functions to a certain extent, it presents numerous drawbacks in its design and practical application, severely restricting improvements in production efficiency and flexibility.

[0003] This results in a complex structure, large space occupation, and poor compatibility. In traditional mechanical structures, the integrated design of conveyor belts and cylinders often leads to a complex overall structure, which not only increases manufacturing and maintenance costs, but also makes the equipment occupy a large area, which is not conducive to space optimization and layout adjustment of the production workshop. Secondly, although cylinder positioning can meet basic positioning needs, its accuracy is limited by factors such as mechanical wear, cylinder stroke limitations and air pressure fluctuations, making it difficult to adapt to high-precision and fast-response production requirements. In addition, the cylinder positioning method has poor compatibility. When it is necessary to replace trays of different specifications or sizes, it is often necessary to adjust or replace the entire positioning mechanism, which is not only time-consuming and labor-intensive, but also increases the downtime of the production line and reduces overall production efficiency.

[0031] Example 1

[0032] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, an adjustable tray conveying mechanism includes a loading mechanism, a conveying mechanism and a unloading mechanism.

[0033] The conveying mechanism is provided with a feeding position and a discharging position, and receives the material tray conveyed by the loading mechanism and conveys it to the unloading mechanism, wherein the conveying mechanism includes: a pushing mechanism, a reference track and a movable track;

[0034] The reference track and the movable track are arranged in parallel in the horizontal direction, and the reference track and the movable track can be connected to the loading mechanism at the feeding position, and the reference track and the movable track can be connected to the unloading mechanism at the discharging position;

[0035] The pushing mechanism is arranged in the gap between the reference track and the movable track to drive the material tray to be transported along the track;

[0036] The movable track is connected to a width adjustment component, which can adjust the distance between the movable track and the reference track to accommodate trays of different sizes;

[0037] Along the conveying direction of the material tray, the loading mechanism is located upstream of the conveying mechanism, and the loading mechanism is connected to the feeding position of the conveying mechanism, and the loading mechanism lifts the material tray to be processed to the starting position of the track;

[0038] Along the conveying direction of the material tray, the unloading mechanism is located downstream of the conveying mechanism to convey the material tray conveyed by the conveying mechanism out.

[0039] Using a width-adjusting assembly connected to the movable track, the mechanism can easily adjust the distance between the movable track and the base track to accommodate trays of varying sizes. This flexibility significantly expands the equipment's application range, reduces the need to replace or adjust equipment due to varying tray sizes, and improves production efficiency and flexibility. The seamless integration of the loading, conveying, and unloading mechanisms enables fully automated handling of trays from entry, conveying, and exit. This not only reduces manual intervention and labor intensity, but also improves operational consistency and accuracy, preventing human error.

[0040] Example 2

[0041] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, an adjustable tray conveying mechanism includes a loading mechanism, a conveying mechanism and a unloading mechanism.

[0042] The conveying mechanism is provided with a feeding position and a discharging position, and receives the material tray conveyed by the loading mechanism and conveys it to the unloading mechanism, wherein the conveying mechanism includes: a pushing mechanism, a reference track and a movable track;

[0043] The reference track and the movable track are arranged in parallel in the horizontal direction, and the reference track and the movable track can be connected to the loading mechanism at the feeding position, and the reference track and the movable track can be connected to the unloading mechanism at the discharging position;

[0044] The pushing mechanism is arranged in the gap between the reference track and the movable track to drive the material tray to be transported along the track;

[0045] The movable track is connected to a width adjustment component, which can adjust the distance between the movable track and the reference track to accommodate trays of different sizes;

[0046] Along the conveying direction of the material tray, the loading mechanism is located upstream of the conveying mechanism, and the loading mechanism is connected to the feeding position of the conveying mechanism, and the loading mechanism lifts the material tray to be processed to the starting position of the track;

[0047] Along the conveying direction of the material tray, the unloading mechanism is located downstream of the conveying mechanism to convey the material tray conveyed by the conveying mechanism out.

[0048] Using a width-adjusting assembly connected to the movable track, the mechanism can easily adjust the distance between the movable track and the base track to accommodate trays of varying sizes. This flexibility significantly expands the equipment's application range, reduces the need to replace or adjust equipment due to varying tray sizes, and improves production efficiency and flexibility. The seamless integration of the loading, conveying, and unloading mechanisms enables fully automated handling of trays from entry, conveying, and exit. This not only reduces manual intervention and labor intensity, but also improves operational consistency and accuracy, preventing human error.

[0049] The loading mechanism includes a lifting module and a separation cylinder. The lifting module is located below the conveyor feed station to lift manually placed trays to the conveyor feed station, while the separation cylinder is located above the conveyor feed station to separate stacked trays. The lifting module design not only simplifies the loading process but also ensures the precise positioning of the trays before delivery, providing a stable foundation for subsequent delivery. The separation cylinder solves a major problem with stacked trays during automatic loading. The separation cylinder easily separates stacked trays, ensuring that only one tray is delivered at a time, avoiding conveying confusion or failures caused by stacking.

[0050] Four sets of loading supports are installed above the conveyor feed station to position the trays lifted by the lifting module. The design of the loading supports reduces the shaking and deviation of the trays before conveying, improving the accuracy and stability of conveying.

[0051] The unloading mechanism includes a check mechanism and a discharge cylinder. The check mechanism is located below the conveyor discharge point to lift the tray above the check mechanism, while the discharge cylinder is located above the conveyor discharge point to receive the tray and prevent backflow. The design of the discharge cylinder ensures a smooth transition of the tray during unloading, avoiding damage or confusion caused by sudden drops or misalignment. The check mechanism, a key component of the unloading mechanism, is located above the conveyor discharge point. Its primary function is to receive the tray and effectively prevent it from flowing back into the conveyor. This design not only improves unloading accuracy but also avoids production interruptions or errors caused by tray backflow.

[0052] Four sets of unloading supports are installed above the conveyor mechanism's discharge position to position the trays lifted by the unloading cylinders. The design of these supports ensures stability and accuracy during unloading, laying a solid foundation for subsequent processing, assembly, or storage.

[0053] The pusher mechanism consists of a pusher frame, which connects the movable track and the base track, and a support bracket, which is mounted on the pusher frame to lift and push the tray. The pusher mechanism's design not only ensures tray stability during transport but also reduces friction and wear between the tray and the track by directly lifting and pushing, extending the equipment's service life.

[0054] The pusher mechanism also includes a conveyor belt and a conveyor motor. The conveyor motor is mounted on the pusher frame and connected to the conveyor belt to drive the conveyor belt's movement. The conveyor belt is connected to the lifting bracket to push the lifting bracket. The conveyor motor can adjust the conveyor belt's operating speed according to actual production needs. This flexibility enables the pusher mechanism to adapt to the conveying requirements of different production scenarios, improving the adaptability and efficiency of the production line. The introduction of the conveyor belt and conveyor motor simplifies the structural design of the pusher mechanism. Compared with traditional mechanical pushing methods, this design is more compact, lightweight, and easy to install and maintain.

[0055] The working principle of this device is as follows: the material tray is manually placed in the feeding bin, the lifting module rises and rises to the horizontal position of the separation cylinder, lifting all the material trays, then the separation cylinder retracts, the lifting module descends, the separation cylinder rises out, clamps the position of the second material tray, the lifting module descends, and a single material tray falls to the feeding position of the conveying mechanism. The pushing mechanism moves to the front end and pushes the material tray forward; after the material is pushed into place, the pushing mechanism moves back a distance to avoid the position, and then moves to the initial position to push the next product, and pushes the material in sequence until the material tray is pushed to the discharge position of the conveying mechanism; after the material tray reaches the discharge position of the conveying mechanism, the unloading cylinder rises, lifts the material tray, pushes the non-return mechanism, and after the unloading cylinder reaches the highest position, the non-return mechanism disengages from the material tray and returns to its position, the unloading cylinder descends, and the product follows the cylinder down, and the non-return mechanism catches the product during the descent.

[0056] Example 3

[0057] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, an adjustable tray conveying mechanism includes a loading mechanism, a conveying mechanism and a unloading mechanism.

[0058] The conveying mechanism is provided with a feeding position and a discharging position, and receives the material tray conveyed by the loading mechanism and conveys it to the unloading mechanism, wherein the conveying mechanism includes: a pushing mechanism, a reference track and a movable track;

[0059] The reference track and the movable track are arranged in parallel in the horizontal direction, and the reference track and the movable track can be connected to the loading mechanism at the feeding position, and the reference track and the movable track can be connected to the unloading mechanism at the discharging position;

[0060] The pushing mechanism is arranged in the gap between the reference track and the movable track to drive the material tray to be transported along the track;

[0061] The movable track is connected to a width adjustment component, which can adjust the distance between the movable track and the reference track to accommodate trays of different sizes;

[0062] Along the conveying direction of the material tray, the loading mechanism is located upstream of the conveying mechanism, and the loading mechanism is connected to the feeding position of the conveying mechanism, and the loading mechanism lifts the material tray to be processed to the starting position of the track;

[0063] Along the conveying direction of the material tray, the unloading mechanism is located downstream of the conveying mechanism to convey the material tray conveyed by the conveying mechanism out.

[0064] This flexibility greatly expands the equipment's application range, reduces the need to replace or adjust equipment due to changes in tray size, and improves production efficiency and flexibility. The seamless integration of the loading, conveying, and unloading mechanisms automates the entire tray processing process, from loading, conveying, to removal. This not only reduces manual intervention and labor intensity, but also improves operational consistency and accuracy, preventing human error.

[0065] The loading mechanism includes a lifting module and a separation cylinder. The lifting module is located below the conveyor feed station to lift manually placed trays to the conveyor feed station, while the separation cylinder is located above the conveyor feed station to separate stacked trays.

The pusher mechanism's design not only ensures tray stability during transport but also reduces friction and wear between the tray and the track by directly lifting and pushing, extending the equipment's service life.

[0070] The pusher mechanism also includes a lifting cylinder, mounted on a support bracket to control contact between the bracket and the tray. The introduction of the lifting cylinder increases the pusher mechanism's flexibility. When transport is required, the lifting cylinder quickly extends the support bracket, making contact with the tray and pushing it forward. This design allows the pusher mechanism to more flexibly respond to various changes in the production process, improving the adaptability and efficiency of the production line.

[0071] The pusher mechanism also includes a conveyor belt and a conveyor motor. The conveyor motor is mounted on the pusher frame and connected to the conveyor belt to drive the conveyor belt's movement. The conveyor belt is connected to the lifting bracket to push the lifting bracket. The conveyor motor can adjust the conveyor belt's operating speed according to actual production needs. This flexibility enables the pusher mechanism to adapt to the conveying requirements of different production scenarios, improving the adaptability and efficiency of the production line. The introduction of the conveyor belt and conveyor motor simplifies the structural design of the pusher mechanism. Compared with traditional mechanical pushing methods, this design is more compact, lightweight, and easy to install and maintain.

[0072] The device works as follows: A tray is manually placed in the loading bin. The lifting module rises to the level of the separation cylinder, lifting all trays. The separation cylinder then retracts, causing the lifting module to descend, and the separation cylinder to rise, locking the second tray in place. The lifting module then descends, allowing a single tray to land on the feed position of the conveyor mechanism. The pusher mechanism moves to the front, the lifting cylinder rises, and the pusher mechanism pushes the tray forward via the lifting bracket. During the pushing process, the trapezoidal track of the movable track presses the tray through the preload force of the elastic member. Once the tray is in place, it is clamped against the trapezoidal track, providing a positioning mechanism. After the material is pushed into place, the pushing mechanism moves back a distance to avoid the position, then moves back to its initial position to push the next product, and pushes the materials in sequence until the material tray is pushed to the conveyor discharge position. After the material tray reaches the conveyor discharge position, the unloading cylinder rises, lifting the material tray and pushing the non-return mechanism. After the unloading cylinder reaches its highest position, the non-return mechanism disengages from the material tray and returns to its original position. The unloading cylinder descends, and the product follows the cylinder. The non-return mechanism catches the product during the descent. The width adjustment component can be used to adjust the distance between the movable track and the base track to accommodate different sizes of material trays.

[0082] The movable track is also equipped with an elastic module consisting of a trapezoidal track and an elastic member. The trapezoidal track is fixed to the movable track via the elastic member to clamp and position the conveyed trays. The trapezoidal track design ensures a stable clamping force when in contact with the trays. The elastic member allows the trapezoidal track to flexibly accommodate trays of varying sizes and shapes, ensuring they remain in a stable position during conveyance. This clamping and positioning method not only improves conveying accuracy but also effectively prevents the trays from shifting or slipping during transport.

Its primary function is to receive the tray and effectively prevent it from flowing back into the conveyor. This design not only improves unloading accuracy but also avoids production interruptions or errors caused by tray backflow.

[0103] Four sets of unloading supports are installed above the conveyor mechanism's discharge position to position the trays lifted by the unloading cylinders. The design of these supports ensures stability and accuracy during unloading, laying a solid foundation for subsequent processing, assembly, or storage.

[0104] The pusher mechanism consists of a pusher frame, which connects the movable track and the base track, and a support bracket, which is mounted on the pusher frame to lift and push the tray. The pusher mechanism's design not only ensures tray stability during transport but also reduces friction and wear between the tray and the track by directly lifting and pushing, extending the equipment's service life.

[0105] The pusher mechanism also includes a conveyor belt and a conveyor motor. The conveyor motor is mounted on the pusher frame and connected to the conveyor belt to drive the conveyor belt's movement. The conveyor belt is connected to the lifting bracket to push the lifting bracket. The conveyor motor can adjust the conveyor belt's operating speed according to actual production needs. This flexibility enables the pusher mechanism to adapt to the conveying requirements of different production scenarios, improving the adaptability and efficiency of the production line. The introduction of the conveyor belt and conveyor motor simplifies the structural design of the pusher mechanism. Compared with traditional mechanical pushing methods, this design is more compact, lightweight, and easy to install and maintain.

[0106] The device works as follows: a tray is manually placed in the loading hopper. The lifting module rises to the level of the separating cylinder, lifting all trays. The separating cylinder then retracts, causing the lifting module to descend, raising the separating cylinder to lock the second tray in place. The lifting module then descends, allowing the tray to drop onto the conveyor feed position. The pushing mechanism then moves to the front, pushing the tray forward. Once the tray is in place, it moves back a distance to avoid a product, then returns to its initial position to push the next product, and so on, until the tray reaches the conveyor discharge position. Once the tray reaches the conveyor discharge position, the unloading cylinder rises, lifting the tray and disengaging the check mechanism. Once the unloading cylinder reaches its highest position, the check mechanism disengages the tray and returns to its original position. The unloading cylinder then descends, and the product follows it, with the check mechanism catching the product during its descent. The width adjustment assembly allows the distance between the active track and the base track to be adjusted to accommodate trays of varying sizes.

[0107] Advantages of the implementation of the present invention: Through the width adjustment component, the mechanism can easily adjust the distance between the movable track and the reference track, thereby adapting to trays of different sizes and specifications, reducing the need to replace or adjust equipment due to changes in tray size. The seamless connection between the loading mechanism, the conveying mechanism and the unloading mechanism realizes the fully automated processing of the tray from entry, conveying to exit. The lifting cylinder can quickly extend the lifting bracket, contact the tray and push the tray forward. This design improves the adaptability and efficiency of the production line. Through the action of the elastic part, the trapezoidal track can flexibly adapt to trays of different sizes and shapes. This clamping and positioning method improves the accuracy of transportation and effectively prevents the tray from shifting or slipping during transportation. The adjusting screw can accurately adjust the distance between the movable track and the pushing mechanism through its rotational movement. When handling trays of different sizes and shapes, this precision is crucial to ensure the stability and accuracy of the tray during transportation.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
