Description

Technical Field

[0001] This utility model relates to an NB-IoT module unloading mechanism, belonging to the field of communication module assembly technology. Background Technology

[0002] NB-IoT (Narrowband Internet of Things) modules are hardware modules that support NB-IoT communication technology and are widely used in Internet of Things (IoT) devices to achieve low-power, long-range wireless communication. NB-IoT is an emerging communication technology based on the LTE (Long Term Evolution, 4G) standard, designed specifically for large-scale IoT applications, and is particularly suitable for connecting devices with low data rates, low power consumption, and low cost.

[0003] When assembling an NB-IoT communication module, it is necessary to assemble its bottom cover, PCB, and outer shell. After assembly, the finished product is usually in an inverted state because it needs to be positioned and automatically screwed on. In the automated production process, the inverted product is not easy to take out and store in an orderly manner, which is not conducive to the subsequent orderly arrangement and testing of the product, affecting the automated testing of the product and the automation coverage of the assembly line. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an NB-IoT module unloading mechanism for automatically transferring assembled module products. This mechanism can automatically flip and transfer products without human intervention, which is conducive to the orderly arrangement of processed module products to facilitate the advancement of subsequent automation work.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] This utility model provides an NB-IoT module unloading mechanism, comprising:

[0007] The material supply department is responsible for supplying module products that are ready to be cut.

[0008] The flipping component is used to grab and flip the modular product.

[0009] A transfer assembly is used to grasp a module product that has been flipped by a flipping assembly. The transfer assembly includes at least a gripper and a first moving module for driving the gripper to move. The gripper includes a mounting plate, on which a support ring plate and multiple suction cups are mounted. The bottom of each suction cup is corrugated. The bottom height of the support ring plate is within the range of the height of the corrugated tube.

[0010] The unloading assembly includes a positioning disk and a second moving module for driving the positioning disk to move. The positioning disk is used to receive and position the module product grasped by the gripper.

[0011] Specifically, the extension of the straight line containing each suction cup is perpendicular to the upper surface of the module product.

[0012] Specifically, the support ring plate can form a ring-shaped area on the upper surface of the module product, and together with the upper surface of the module product, it forms a closed cavity, which is connected to an external negative pressure generating device.

[0013] Specifically, a rubber pad is provided below the support ring plate, and multiple suction cups are disposed inside the support ring plate. The bottom surface of the rubber pad is located within the height range of the corrugated pipe.

[0014] Specifically, the mounting plate has a connecting hole inside, and multiple suction cups are connected to an external negative pressure generating device through the connecting hole.

[0015] Specifically, the flipping assembly includes a fixed plate and a sliding plate that slides vertically relative to the fixed plate. A first drive mechanism for driving the sliding plate to rise and fall is installed on the fixed plate. A gripper assembly for gripping the module product is provided above the sliding plate. A second drive mechanism for driving the gripper assembly to rotate is also installed on the sliding plate.

[0016] Specifically, the gripper assembly includes two L-shaped plates arranged in a mirror image and a third drive mechanism for driving the two L-shaped plates to move closer or further apart.

[0017] Specifically, the upper surface of the positioning disk is provided with a number of positioning pins, and the upper surface of each positioning pin is provided with a chamfer. The positioning pin is used to match the positioning hole provided below the module product.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0019] This invention provides a flipping component and a transfer component for receiving materials, which flips the finished modular products and picks them up and transfers them in an orderly manner. This allows for the orderly and automatic discharge of modular products without human intervention, ensuring that the products flow out in an orderly manner in a corrected state. This improves the automation coverage of the entire production line and facilitates the implementation of automated testing processes at the back end. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0026] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0028] This utility model provides an NB-IoT module unloading mechanism for automatically transferring assembled module products. It enables automatic flipping and transfer of products without manual intervention, facilitating the orderly arrangement of processed module products and promoting subsequent automation. To achieve automated unloading, the device includes a feeding unit 1, which supplies the module products to be unloaded and can be moved to the unloading position after assembly; a flipping component 2, used to grasp and flip the module products, which can be performed using a multi-axis robotic arm; and a transfer component 3, used to grasp the module products flipped by the flipping component 2. After the block product is flipped, its surface presents an irregular curved surface. Therefore, to ensure good gripping during handling, the transfer assembly 3 is configured to include at least a gripper 31 and a first moving module 32 for driving the gripper 31. The first moving module 32, to place the gripped block product, can be configured to include at least a vertical moving module and a horizontal moving module, enabling it to lift and transfer the gripped block product to the required location for placement. The gripper 31 is responsible for accurately gripping the block product. To achieve good gripping and adsorption on the curved surface of the block product, the gripper 31 includes a mounting plate 311. Specifically, a support ring plate 312 and multiple suction cups 313 are mounted on the mounting plate 311. (See reference...) Figure 1 As shown, the bottom of each suction cup 313 is designed to be corrugated, and the bottom surface of the support ring plate 312 is positioned within the height range of the corrugated tube. With this design, when the gripper 31 grasps the module product, the suction cup 313 first contacts the curved surface of the module product, and then the support ring plate 312 connects with the surface of the module product. The structure of the support ring plate 312 can be referenced... Figure 4As shown, the bellows end of the suction cup 313 is compressed by a certain offset in the length direction, thereby ensuring good contact and adsorption at the end of the suction cup 313. During adsorption, multiple suction cups 313 work together, and the support ring plate 312 prevents the module product from tilting due to unstable negative pressure of the suction cup 313. That is, it can ensure the placement position of the module product during adsorption, and at the same time protect the structure of the suction cup 313 to prevent deformation of the suction cup 313 during adsorption. In order to facilitate the discharge of the module product after adsorption, the device also includes a discharge component 4, which includes a positioning plate 41 and a second moving module 42 for driving the positioning plate 41 to move. At this time, the positioning plate 41 is used to receive and position the module product grasped by the gripper 31. That is, after the gripper 31 disconnects the adsorption, the positioning plate 41 receives it, and the second moving module 42 orderly transfers the processed material out (a linear moving module, such as a combination of rodless cylinder and slide rail slider, can be directly used; the specific implementation is not limited here). To improve the suction effect of suction cup 313, you can refer to... Figure 3 As shown, the extension line of the straight line where each suction cup 313 is located can be set to be perpendicular to the upper surface of the module product, thereby ensuring good adsorption at the contact point.

[0029] This utility model provides an NB-IoT module unloading mechanism, specifically offering a method to improve the stability of the adsorption effect when handling module products. Specifically, a support ring plate 312 is provided to form a ring-shaped area on the upper surface of the module product, and together with the upper surface of the module product, forms a closed cavity. The closed cavity is connected to an external negative pressure generating device (not shown in the figure). When the outer shell of the module product has a certain regularity, the support ring plate 312 can act as an adsorption mechanism to adsorb the product as a whole, and at the same time, it can be combined with multiple suction cups 313 to realize the handling of the module product. To further ensure a good sealing contact, a rubber pad can be placed below the support ring plate 312 for flexible contact. At this time, multiple suction cups 313 can be placed inside the support ring plate 312, and the bottom height of the rubber pad is set within the height range of the bellows. By placing the suction cups 313 inside the support ring plate 312, the vacuum effect can be directly applied to the cavity of the support ring plate 312 to form an overall negative pressure after some suction cups 313 fail. That is, even if the cavity formed by the support ring plate 312 is not connected to the negative pressure, a certain degree of adsorption safety can still be guaranteed, and the module product can be prevented from tilting and falling off after individual suction cups 313 fail.

[0030] The present invention provides an NB-IoT module unloading mechanism. In order to facilitate the simultaneous control of these suction cups 313, a connecting hole can be provided inside the mounting plate 311. Multiple suction cups 313 are connected to an external negative pressure generating device through the connecting hole. That is, these suction cups 313 can be controlled by a single air path, which simplifies the control method of the mechanism.

[0031] This utility model provides an NB-IoT module unloading mechanism. If a robotic arm is used to control the flipping of the module product, it would undoubtedly lead to a significant increase in equipment and control costs. To reduce equipment costs, the flipping component 2 includes a fixed plate 21 and a sliding plate 22 that slides vertically relative to the fixed plate 21. Figure 1 As shown, a first drive mechanism 23 for driving the sliding plate 22 to rise and fall is installed on the fixed plate 21. A gripper assembly for gripping the module product is provided above the sliding plate 22. The gripper assembly grips the module product. A second drive mechanism 24 for driving the gripper assembly to rotate is also installed on the sliding plate 22. The second drive mechanism 24 drives the product to flip after being gripped, and the sliding plate 22 can drive the module product to be lifted, thus avoiding the positional conflict that the feeding part 1 may cause during the flipping operation. To achieve good gripping performance, the gripper assembly includes two L-shaped plates 25 arranged in a mirror image and a third drive mechanism 26 for driving the two L-shaped plates 25 to move closer or further apart. Before gripping, the two L-shaped plates 25 are inverted and placed on the upper surface of the product, and can abut against the upper surface to limit the height position. After the L-shaped plates 25 move to the appropriate position, the product is gripped, and then the second drive mechanism 24 drives it to flip over. The flipping angle is 180°. After flipping, it is directly adsorbed and gripped by the suction cup 313. The preferred driving method for the flipping action is to use a rotary cylinder in conjunction with a gripper cylinder. Other implementation methods are not limited here.

[0032] This utility model provides an NB-IoT module unloading mechanism. In order to ensure the positioning of the module product before and after transportation, a number of positioning pins 43 are provided on the upper surface of the positioning disk 41. Each positioning pin 43 has a chamfer on its upper surface. These positioning pins 43 are used to match the positioning holes provided below the module product. They can position the module product after it is placed to prevent it from falling or shifting position during transportation.

[0033] The above description is only a preferred embodiment of the present 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 the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
