Description

Technical Field

[0001] The invention belongs to the technical field of desktop forming equipment, and in particular relates to a human-machine combination line of a pull-out table and a processing method thereof. Background Art

[0002] Compared with wooden tables, fabric tables or leather tables, glass tables have the advantages of not being deformed by humidity, being easier to clean, being safer and more environmentally friendly, and being pollution-free and radiation-free. At the same time, the structural design of glass tables tends to be simpler and more diversified, especially the structural design of retractable desktops, which has been vigorously promoted and used because of its ability to meet a variety of needs and its ease of use.

[0003] During the assembly of the pull-out glass table, the glass needs to be embedded into the frame structure. The traditional assembly method usually uses manual handling. Because the product material is large and heavy, the manual work of the employees is heavy, and the labor load is large. In addition, the glass is easily damaged during the handling process, resulting in a lot of waste in handling. Summary of the invention

[0004] In order to make up for the deficiencies of the prior art, the present invention provides a pull-out table human-machine combination line and a processing method thereof, so as to solve the technical problem that the labor load of workers is heavy and the waste of transportation is easily caused.

[0005] To achieve the above purpose, the specific technical solutions of the present invention are as follows: In a first aspect, a human-machine integration line for a pull-out table includes a loading station, a transfer and conveying mechanism, an assembly and output mechanism, a station switching mechanism, a fixed frame loading mechanism, and a unloading and flipping mechanism.

[0006] The transfer and conveying mechanism can transfer the materials stored in the loading station to the assembly output mechanism, and complete the preliminary assembly of the frame body through the assembly output mechanism.

[0007] The station switching mechanism is used to receive the output frame body and drive the output frame body to pass through the stations where the fixed frame loading mechanism and the unloading flipping mechanism are located in sequence.

[0008] The fixed frame loading mechanism is used to transport the fixed frame to the frame body, and the fixed frame is fixed to the frame body to form a finished product. The unloading and turning mechanism is used to turn over the assembled finished parts and output them.

[0009] Furthermore, the blanking and turning mechanism comprises a blanking frame, a blanking and turning assembly and a third belt conveyor assembly. The third belt conveyor assembly is installed on the blanking frame and is used to receive the assembled finished parts and output them after being turned over by the blanking and turning assembly.

[0010] Furthermore, the blanking and flipping assembly includes a flipping drive motor, a limit support frame and a limit cylinder. The limit support frame is rotatably connected to the blanking frame and can be rotated under the drive of the flipping drive motor. A card slot with an open outer end is provided on the limit support frame. The limit cylinder is installed at the notch of the card slot and is used to clamp the finished product entering the card slot.

[0011] Furthermore, there are a plurality of position-limiting support frames, each of which is arranged on the blanking frame at intervals and connected by a rotating shaft. The flip driving motor is fixed on the blanking frame, and the output end is connected to the rotating shaft.

[0012] Furthermore, the transfer and conveying mechanism includes a first loading robot, a gripping mechanism and a displacement drive assembly. The first loading robot can move laterally under the drive of the displacement drive assembly. The gripping mechanism is installed on the movable end of the first loading robot and is used to complete the adsorption of the glass and the clamping of the material frame.

[0013] Furthermore, the gripping mechanism includes a frame clamping assembly and a glass adsorption assembly. The frame clamping assembly includes a plurality of first double-headed cylinders. The first double-headed cylinders can clamp and release the material frame under the drive of an external air source. The glass adsorption assembly includes a plurality of suction cups. The suction cups can adsorb or release the glass under the action of an external air source.

[0014] Furthermore, the displacement drive assembly includes a sliding frame, a linear slide and a displacement drive motor. The first feeding robot is slidably connected to the linear slide via the sliding frame and can move under the drive of the displacement drive motor.

[0015] Furthermore, the assembly output mechanism includes an assembly base, a first belt conveyor assembly and a plurality of clamping cylinders. Each clamping cylinder is symmetrically arranged on both sides of the assembly base for clamping the transferred material frame. The first belt conveyor assembly is used to output the frame body that has completed the preliminary assembly.

[0016] Furthermore, the station switching mechanism includes a transmission frame, a second belt conveyor assembly and a plurality of rollers. The second belt conveyor assembly is mounted on the transmission frame, and the conveying direction is the same as the conveying direction of the assembly output mechanism. The rollers are arranged in sequence on the transmission frame and are rotatably connected to the transmission mechanism to form a transmission channel. The conveying direction of the transmission channel is perpendicular to the conveying direction of the second belt conveyor assembly.

[0017] In a second aspect, a method for processing a pull-out table human-machine combination line body using the device described in the first aspect is provided, and the specific steps are as follows: Step 1: The transfer and conveying mechanism transfers the materials stored in each loading station to the assembly output mechanism in turn, and assembles them manually; Step 2: The assembly output mechanism outputs the completed preliminary assembly frame body to the station switching mechanism; the frame body is transferred to the station where the fixed frame feeding mechanism is located through the station switching mechanism; Step 3: The fixed frame feeding mechanism conveys the fixed frame to the frame body, and is manually assembled to form a finished product; Step 4: The assembled finished parts are transferred to the station where the unloading and flipping mechanism is located through the station switching mechanism, and are flipped and output through the unloading and flipping mechanism.

[0018] Compared with the prior art, the present invention has the following advantages: 1. The present invention realizes automatic loading of materials such as glass and frames by arranging a transfer conveying mechanism, an assembly output mechanism, a fixed frame loading mechanism and a unloading flipping mechanism in sequence along the workstation transfer mechanism, thereby reducing the labor burden of the staff and improving the processing efficiency.

[0019] 2. The present invention sets a station switching mechanism and sets an assembly output mechanism at the input end of the station switching mechanism, so that during the assembly process, the material can pass through each processing station in sequence through the station switching mechanism, thereby solving the waste of material handling and improving the output of the entire line. At the same time, the use of rubber rollers reduces the scratching of the material, so that the quality of the final finished product is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In the description of the present invention, it is necessary to understand that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "center", "end", "length", "outer end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] like Figure 1 and 2 As shown, a pull-out table man-machine combination line body includes a loading station 1, a transfer conveying mechanism 2, an assembly output mechanism 3, a station switching mechanism 4, a fixed frame loading mechanism 5, and a material unloading flipping mechanism 6. Among them, the transfer conveying mechanism 2 can transfer the material frame stored in the loading station 1 to the assembly output mechanism 3, and after completing the material frame transfer, the glass in the loading station 1 is placed on the middle frame and the side frame in turn, and through manual assembly, a preliminary assembled frame body is formed.

[0025] The assembly output mechanism 3 is used to output the frame after glass assembly to the station switching mechanism 4. The station switching mechanism 4 can receive the output frame body and drive the output frame body to pass through the station where the fixed frame feeding mechanism 5 and the unloading flipping mechanism 6 are located in sequence. The fixed frame feeding mechanism 5 is used to transport the fixed frame to the frame body. The fixed frame is assembled with the corresponding frame body by workers. The unloading flipping mechanism 6 is used to flip the finished assembled parts and output them.

[0026] like Figure 2As shown, the transfer conveying mechanism 2 includes a first loading robot 2-1, a gripping mechanism and a displacement drive assembly 2-2. The first loading robot 2-1 can switch between the loading stations 1 under the drive of the displacement drive assembly 2-2. The gripping mechanism is installed at the active end of the first loading robot 2-1 to complete the adsorption of the glass and the clamping of the material frame.

[0027] Specific structure such as Figure 3 As shown, the gripping mechanism includes a frame clamping assembly 2-3 and a glass adsorption assembly 2-4. Among them, the frame clamping assembly 2-3 includes a first mounting frame 2-3-1 and a plurality of first double-headed cylinders 2-3-2. The first mounting frame 2-3-1 is fixed on the movable end of the first feeding robot 2-1. Each first double-headed cylinder 2-3-2 is sequentially installed on both sides of the first mounting frame 2-3-1. First clamps are fixed on the two output shafts of the first double-headed cylinder 2-3-2. During operation, the two output shafts of the first double-headed cylinder 2-3-2 extend outward or retract inward under the drive of an external air source, thereby driving the two first clamps to complete the clamping and loosening of the material frame.

[0028] The glass adsorption assembly 2-4 includes a suction cup bracket, a pushing cylinder and a plurality of suction cups. Among them, the pushing cylinder is fixed on the first mounting frame 2-3-1, and can drive the suction cup bracket to extend outward or move inward. The suction cups are arranged in sequence on the suction cup bracket. In the initial state, the pushing cylinder drives the suction cup bracket to move inward to the extreme position to avoid interference between the outer end of each suction cup and the first clamping claw on each first double-headed cylinder 2-3-2. When glass transfer is required, the pushing cylinder drives the suction cup bracket to move outward to the extreme position, and the suction cup is extended to the position of the first clamping claw under the drive of the suction cup bracket. Under the action of the external air source, the suction cup generates negative pressure to adsorb the glass to be transferred.

[0029] In this embodiment, the displacement drive assembly 2-2 includes a sliding frame, a linear slide and a displacement drive motor. The first feeding robot 2-1 is slidably connected to the linear slide through the sliding frame. The displacement drive motor is fixed on the sliding frame, and a gear is fixed at the output end. A rack meshing with the gear is fixed on the linear slide. During the processing, the gear is driven to rotate by the displacement drive motor, and with the cooperation of the rack, the sliding frame is gradually driven to slide, thereby completing the movement of the first feeding robot 2-1.

[0030] like Figure 4As shown, the material frame is divided into a side frame and a middle frame. There are two assembly output mechanisms 3, which are used to assemble the glass in the middle frame and the glass in the side frame, and output to one side of the station switching mechanism 4 after the assembly is completed. The assembly output mechanism 3 includes an assembly base 3-1, a clamping cylinder 3-2 and a first belt conveyor assembly 3-3. Among them, there are two clamping cylinders 3-2. The two clamping cylinders 3-2 are symmetrically arranged on the assembly base 3-1, and can clamp the input side frames and middle frames, so as to facilitate the staff to assemble the glass. The first belt conveyor assembly 3-3 is used to output the assembled side frames and middle frames to one side of the station switching mechanism 4. The first belt conveyor assembly 3-3 is an existing well-known technology and will not be described in detail here.

[0031] like Figure 5 As shown, the station switching mechanism 4 includes a transmission frame 4-1, a second belt conveyor assembly 4-2 and a plurality of rollers 4-3. Among them, the second belt conveyor assembly 4-2 is installed on the transmission frame 4-1, and the conveying direction is the same as the conveying direction of the assembly output mechanism 3, and is used to receive the middle frame and the side frame output by the assembly output mechanism 3. The rollers 4-3 are arranged in sequence on the transmission frame 4-1, and are all rotatably connected to the transmission mechanism to form a transmission channel for conveying to the fixed frame loading mechanism 5 and the unloading flipping mechanism 6. The conveying direction of the conveying channel is perpendicular to the conveying direction of the second belt conveyor assembly 4-2.

[0032] In this embodiment, the roller 4-3 is made of rubber. The second belt transmission component 4-2 is a prior art known in the art and will not be described in detail herein.

[0033] The fixed frame feeding mechanism 5 includes a second feeding robot and a plurality of second double-headed cylinders. A second mounting frame is fixed on the moving end of the second feeding robot. The second double-headed cylinders are arranged on both sides of the second mounting frame. Second clamps are fixed on both output shafts of the second double-headed cylinders, which can clamp and release the fixed frame under the drive of the second double-headed cylinders, and then realize the transportation of the fixed frame with the assistance of the second feeding robot.

[0034] like Figure 6 As shown, the material unloading and turning mechanism 6 includes a material unloading frame 6-1, a material unloading and turning assembly 6-2 and a third belt conveyor assembly 6-3. There are two third belt conveyor assemblies 6-3, which are respectively installed at the input end and the output end of the material unloading frame 6-1, and are used to convey the assembled frame to the material unloading and turning assembly 6-2, and output it after the turning is completed.

[0035] like Figure 6 and 7As shown, the material unloading and flipping assembly 6-2 includes a flipping drive motor 6-2-1, a limit support frame 6-2-2 and a limit cylinder 6-2-3. Among them, the limit support frame 6-2-2 is rotatably connected to the material unloading frame 6-1, and can be rotated under the drive of the flipping drive motor 6-2-1. A card slot 6-2-4 with an open outer end is provided on the limit support frame 6-2-2. The assembled finished parts can enter the card slot 6-2-4 under the transportation of the third belt conveyor assembly 6-3 at the input end. The limit cylinder 6-2-3 is installed at the notch of the card slot 6-2-4, and is used to complete the clamping of the finished parts entering the card slot 6-2-4, so as to avoid the finished parts from being detached during the flipping process of the limit support frame 6-2-2, causing a safety accident.

[0036] In this embodiment, there are two limit support frames 6-2-2. The two limit support frames 6-2-2 are arranged on the unloading frame 6-1 at intervals, and are both rotatably connected to the unloading frame 6-1. The two limit support frames 6-2-2 are connected by a rotating shaft. The outer end of the rotating shaft is connected to the output shaft of the flip driving motor 6-2-1, and can be driven by the flip driving motor 6-2-1 to rotate, thereby driving the limit support frame 6-2-2 to rotate, so as to realize the flipping of the finished product.

[0037] The assembly and transportation steps of the pull-out table man-machine combination line are as follows: Step 1: The first loading robot 2-1, driven by the displacement drive assembly 2-2, passes through the loading station 1 storing the side frame and the middle frame in sequence. The grasping mechanism on the first loading robot 2-1 moves to the location of the side frame and the middle frame under the drive of the first loading robot 2-1, and grasps the frame through the first gripper.

[0038] Step 2: The side frame and the middle frame grasped by the grasping mechanism are transferred to the corresponding assembly base 3-1 by the first loading robot 2-1, and are clamped by the clamping cylinder 3-2 on the assembly base 3-1.

[0039] Step 3: The first loading robot 2-1 moves to the position of the loading station 1 where the glass is stored under the drive of the displacement drive component 2-2. The suction cup on the mobile end of the first loading robot 2-1 extends outward under the push of the push cylinder, and adsorbs the glass under the action of the external air source. The first loading robot 2-1 transfers the adsorbed glass to the side frame and the middle frame.

[0040] Step 4: manually assemble the side frames, the middle frame and the glass, and after the assembly is completed, release the clamping of the side frames and the middle frame by the clamping cylinders 3-2 on each assembly base 3-1.

[0041] Step 5: The side frame and the middle frame are sequentially output to the station switching mechanism 4 through the first belt conveyor assembly 3-3 on each assembly base 3-1. The side frame and the middle frame output to the station switching mechanism 4 are pulled by workers to the station where the fixed frame feeding mechanism 5 is located.

[0042] Step six: clamp the fixed frame by the second clamping claws on the second loading robot, loosen it when transferring it to the side frame and the middle frame, and assemble it manually to form a finished product.

[0043] Step 7: The finished part is moved to the station where the material unloading and turning mechanism 6 is located under the drive of the station switching mechanism 4.

[0044] Step 8: The finished product is conveyed by the third belt conveyor assembly 6-3 at the input end of the unloading frame 6-1 and enters the clamping groove 6-2-4 of the limiting support frame 6-2-2. The limiting cylinder 6-2-3 at the end of the clamping groove 6-2-4 is used for limiting clamping.

[0045] Step nine, the limit support frame 6-2-2 is driven by the flip drive motor 6-2-1 to rotate, thereby driving the finished parts to flip, and the finished parts that have completed flipping are output through the third belt conveyor assembly 6-3 located at the output end of the unloading frame 6-1.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
