Description

Technical Field

[0001] This utility model relates to the field of luggage processing technology, and in particular to a luggage shell processing production line. Background Technology

[0002] Currently, the processing of suitcases requires drilling. Whether it is manual or machine drilling, the suitcase blank needs to be placed on the mold manually. After drilling, the suitcase blank also needs to be removed, resulting in low processing efficiency and quality.

[0003] For example, our company's previous patent application, CN202420875778.6, discloses a punching device for bag shells, including a support frame and a collection platform, as well as a translation component, a lifting component, a rotating component, a punching machine, and a carrying component. The translation component is mounted on the support frame; the lifting component is mounted on the translation component and moves with it; the rotating component is mounted on the lifting component and moves with it; the punching machine is mounted at the end of the rotating component and is used to punch holes in the bag shell; the carrying component is mounted on the collection platform and moves back and forth under the control of a carrying motor. In this invention, the support frame is positioned above the middle of the carrying component, providing good stability. The bag shell is located on both sides of the carrying component, away from the punching machine, ensuring safe processing. Through the first and second rotating shafts, the punching machine can drill and cut holes at multiple angles on the top and sides of the bag shell. The circumferential rotation is flexible and efficient, and the drilling process is system-controlled, resulting in a high degree of automation.

[0004] In the above solution, the punching device achieves automated punching, but the operator still needs to place the box blank on the mold and wait for the punching device to finish punching before removing it. This results in low processing efficiency, low automation, and poor safety. At the same time, the accuracy, stability, and consistency of the product cannot be guaranteed. Therefore, it is necessary to provide a box shell processing production line to solve the shortcomings of the existing technology. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] Example 1:

[0026] In this embodiment, as Figure 1-2 As shown, the present invention proposes a box shell processing production line, including a box shell injection molding assembly, a box shell conveying assembly 1, a box shell handling assembly 2, a box shell punching assembly, and a box shell conveying assembly 2 3. The box shell conveying assembly 1 includes a conveying platform 11, a guiding unit 12, a limiting plate 13, and a positioning unit 14. The guiding unit, the limiting plate, and the positioning unit are sequentially installed on the conveying platform 1. The guiding unit guides the box shell 4 on the conveying platform, the limiting plate limits one end of the box shell, and the positioning unit positions both sides of the box shell.

[0027] The box handling assembly includes a support frame 21, a robotic arm unit 22, and a suction cup unit 23. The bottom of the robotic arm unit is fixedly mounted on the support frame by bolts. The top of the suction cup unit is connected to the top of the robotic arm unit. The suction cup assembly at the bottom of the suction cup unit is used to suction, grab, and release the box.

[0028] The suction cup unit includes a mounting frame 231, a suction cup assembly 232, and an air extraction cylinder. The top of the mounting frame is connected to the top of the robotic arm unit, and the bottom of the mounting frame is equipped with a suction cup assembly. Each suction cup in the suction cup assembly is connected to the air extraction cylinder through an air pipe, and the air extraction cylinder extracts and releases air from the suction cup.

[0029] In this example, the box shell injection molding assembly is prior art, and the box shell injection molding assembly is a conventional injection molding machine. A robotic arm for unloading the box shell is installed on the box shell injection molding assembly. The robotic arm can connect the box shell injection molding assembly and the box shell conveying assembly. For example, our company's previous patent application with application number CN202322983855.8 discloses a robotic arm for unloading injection molded box shells. The box shell punching assembly is prior art. For example, our company's previous patent application with application number CN202420875778.6 discloses a bag shell punching device, which can automatically complete the box shell punching work.

[0030] In this example, the suction cylinder is not shown in the figure. The suction cylinder is an existing product. The suction cylinder creates a near-vacuum environment by quickly expelling the air from the suction cup, which directly enhances the suction force and prevents the box from falling off due to insufficient suction force. Then, when the box reaches the designated position, the box is removed by releasing the air.

[0031] In this embodiment, the conveying platform 1 is further configured to include a frame 111, a conveyor belt 112, a conveyor shaft 113, and a conveyor motor 114. The two ends of the conveyor shaft 1 are movably connected to the frame 1, the conveyor belt 1 is wound around the conveyor shaft 1, and the output end of the conveyor motor 1 is connected to one end of the conveyor shaft 1.

[0032] In this example, a conveyor motor is installed at one end of the frame. The conveyor motor can drive the conveyor shaft to rotate, thereby driving the conveyor belt to rotate. The box placed on the conveyor belt moves accordingly. The frame also has rollers arranged in an array. The rollers can support the conveyor belt and the box to prevent the conveyor belt from sagging.

[0033] In this embodiment, the guide unit is further configured to include a fixed plate 121, a curved plate 122, and a buffer pad 123. The fixed plate is installed on both sides of the frame, the curved plate is welded to the fixed plate, and the buffer pad is attached to the surface of the fixed plate.

[0034] In this example, when the box shell passes through the guide assembly, it is guided and limited by the curved panels and the buffer pad. The width between the two curved panels decreases sequentially along the conveying direction, so that the approximate position of the box shell is fixed and located in the middle of the conveyor belt. The buffer pad can prevent the curved panels from scratching the surface of the box shell.

[0035] In this embodiment, the positioning unit is further configured to include a positioning frame 141, a telescopic cylinder 142, and a positioning plate 143. The positioning frame is installed on both sides of the frame, the telescopic cylinder is installed on the positioning frame, the output end of the telescopic cylinder faces the housing, and the output end of the telescopic cylinder is connected to the positioning plate.

[0036] In this example, one end of the box shell is limited by a limiting plate. At this time, two telescopic cylinders extend simultaneously, limiting both sides of the box shell. The position of the box shell on the conveyor belt is fixed, waiting for the box shell handling assembly to handle the box shell. The extension amount of the telescopic cylinder or the installation position of the telescopic cylinder is adjusted in advance according to the width of the box shell.

[0037] In this embodiment, the robotic arm unit is further configured to include a base 221, a rotating base 222, a first motor 223, a first shaft 224, a second motor 225, a second shaft 226, a third motor 227, a third shaft 228, a fourth motor, and a rotating shaft 229. The fourth motor is not marked in the figure. The base is connected to the support frame by bolts, and the bottom of the rotating shaft is fixedly connected to the mounting frame.

[0038] In this example, the rotating base can rotate 360 ​​degrees under the action of motor one. Shaft one is a fixed shaft and is fixedly connected to the rotating base. Shaft two rotates under the action of motor two, shaft three rotates under the action of motor three, and the rotating shaft rotates 360 degrees under the action of motor four. The robotic arm unit is existing technology and will not be described in detail here.

[0039] In this embodiment, the suction area of ​​the suction cup assembly is smaller than the top surface area of ​​the housing to prevent the suction cups in the suction cup assembly from failing to adhere to the surface of the housing and affecting the suction effect. If the sizes do not match, the size of the mounting bracket can be changed or the position of the suction cups can be adjusted.

[0040] In this embodiment, the second housing conveying assembly includes a second frame 31, a second conveyor belt 32, a second conveyor shaft, and a second conveyor motor 33. The two ends of the second conveyor shaft are movably connected to the second frame, the second conveyor belt is wound around the second conveyor shaft, and the output end of the second conveyor motor is connected to one end of the second conveyor shaft.

[0041] In this example, the configuration of the second box shell conveying component is the same as that of the first conveying platform. The second conveyor shaft is not shown in the figure. The second box shell conveying component is used to convey the box shells that have been punched. Therefore, there is no need to limit or position the box shells. The box shells can be directly moved from the box shell punching component to the second box shell conveying component by the box shell handling component. The punched box shells can then be transported to the next assembly step by the second conveyor belt at a constant speed.

[0042] The working principle of this box shell processing production line is as follows: the box shell injection molding component is formed into a box shell through extrusion. A material unloading robotic arm is installed above the box shell injection molding component. The material unloading robotic arm transports the box shell to the box shell conveying component one. After the box shell is guided, limited and positioned on the box shell conveying component one, the box shell is fixed in position. The box shell transporting component reaches the top of the box shell, picks up the box shell, and transports the box shell to the box shell punching component for unloading. After the box shell punching component completes punching the box shell, the box shell transporting component reaches the top of the box shell, picks up the box shell, and transports the box shell to the box shell conveying component two for unloading. The punched box shell is then transported at a constant speed by the second conveyor belt to the next assembly step.
