[0029] like Figure 3As shown, the on-line module 1-1 is used to store the injection molding boxes 5 filled with plug-in panels 7, and is composed of a frame 1-1-1, a conveying roller 1-1-2, a positioning mechanism 1-1-3, a clamping cylinder 1-1-4, and an electric lifting system 1-1-5. The stacked injection molding boxes 5 filled with plug-in panels 7 are placed in the positioning mechanism 1-1-3. The clamping cylinder 1-1-4 is initially extended to support the card slots on both sides of the stacked injection molding boxes 5. When the injection molding boxes 5 need to be put on the line, the electric lifting system 1-1 -5 rises to support the bottom of the stacked injection molding boxes 5 and lifts out the supporting surface of the clamping cylinder 1-1-4. The clamping cylinder 1-1-4 retracts, and the electric lifting system 1-1-5 drops to the height of one injection molding box 5. The clamping cylinder 1-1-4 extends out and inserts into the slots on both sides of the upper stacked injection molding boxes 5. After the electric lifting system 1-1-5 brings the lowest injection molding boxes 5 to the roller conveying plane, the electric lifting system 1-1-5 continues to descend to the starting position, and the conveying roller 1-1-2 transports the injection molding boxes 5 to the downstream work station.

[0030] like Figure 4 As shown, the online module 2 1-2 is used to put empty blister boxes 6 online, and is composed of a frame 2 1-2-1, a conveying roller 2 1-2-2, a positioning mechanism 2 1-2-3, a clamping cylinder 2 1-2-4, a separation cylinder 1-2-5, and a pneumatic lifting system 1-2-6. The stacked empty blister boxes 6 are placed in the positioning mechanism 2 1-2-3, and the clamping cylinder 2 1-2-4 is initially extended to support the stacked blister boxes 6. When the blister boxes 6 need to be put online, the pneumatic lifting system 1-2-6 rises to a height of one stacked blister box under the support surface of the clamping cylinder 2 1-2-4. 6 position, the clamping cylinder three 1-3-4 retracts, the blister box 6 falls on the support surface of the pneumatic lifting system 1-2-6, the clamping cylinder three 1-3-4 extends, and the upper stacked blister box 6 is supported, and the pneumatic lifting system 1-2-6 drops to the initial position, the separation cylinder 1-2-5 first extends vertically and then extends horizontally into the upper side of the bottom blister box 6, the separation cylinder 1-2-5 drops vertically, pulls the blister box 6 out and separates it to the plane of the conveying roller two 1-2-2, the separation cylinder 1-2-5 retracts horizontally, and the conveying roller three 1-3-2 transports the blister box 6 to the downstream work station.

[0031] like Figure 5As shown, the online module 3 1-3 is used to temporarily store the blister boxes 6 filled with plug-in panels 7 online, and is composed of a frame 3 1-3-1, a conveying roller 3 1-3-2, a positioning mechanism 3 1-3-3, a clamping cylinder 3 1-3-4, and an electric lifting system 1-3-5. The stacked blister boxes 6 filled with plug-in panels 7 are manually placed into the positioning mechanism 3 1-3-3. The clamping cylinder 3 1-3-4 is initially extended to support the stacked blister boxes 6. When the blister boxes 6 need to be put online, the electric lifting system The system 1-3-5 rises to support the bottom of the stacked blister boxes 6 and pushes out the plane of the clamping cylinder three 1-3-4. The clamping cylinder three 1-3-4 retracts, and the electric lifting system 1-3-5 descends to the height of one box of blister boxes 6. The clamping cylinder three 1-3-4 extends out to support the upper stacked blister boxes 6. After the electric lifting system 1-3-5 brings one box of blister boxes 6 to the roller conveying plane, the electric lifting system 1-3-5 continues to descend to the starting position, and the blister boxes 6 are conveyed to the rear by the conveying roller three 1-3-2.

[0032] like Figure 6 As shown, the box changing station 2 includes a frame 2-1, a conveying roller 2-2, a three-way module 2-3, a variable pitch module 2-4, a positioning mechanism 2-5, and an electrical control system 2-6. The three-way module 2-3 drives the variable pitch module 2-4 to absorb the plug-in panel 7 from the injection molding box 5 clamped by the positioning mechanism 2-6 into the blister box 6, thereby realizing automatic box changing of the plug-in panel 7 in injection molding boxes 5 and blister boxes 6 of various specifications. The injection molding boxes 5 and blister boxes 6 after box changing are automatically transferred to the next station.

[0033] like Figure 7 As shown, the pitch-changing module 2-4 is composed of a transmission module 2-4-1, a stepper motor 2-4-2, a blade cylinder 2-4-3, and a vacuum suction cup 2-4-4. The stepper motor 2-4-2 is used to drive the central axis 2-4-6 of the transmission module 2-4-1 to rotate, thereby adjusting the spacing change of the four groups of blade cylinders 2-4-3. By controlling the number of 1 to 4 groups of blade cylinders 2-4-3, the transportation and placement of plug-in panels between injection molding boxes 5 and blister boxes 6 with different storage quantities can be realized. Two groups of vacuum suction cups 2-4-4 are used to adsorb a single plug-in panel 7 to avoid interference with the material box cavity, protect the appearance of the plug-in panel 7, and achieve rapid and firm adsorption.

[0034] In this embodiment, the blade cylinder 2-4-3 is connected to the slider 2-4-5, the slider is slidably connected to the transmission module 2-4-1, and the central shaft 2-4-6 is connected to the slider. By rotating the central shaft, the slider is driven to move forward and backward. Figure 7 For example, the two on the left move to the left, and the two on the right move to the right.

[0035] The electrical control system 2-6 provides a quick allocation method for switching the plug-in panel 7 from the injection molding box 5 to the blister box 6 with different storage capacities. Taking the change from the injection molding box 5 with a storage capacity of 10 pieces to the blister box 6 with a storage capacity of 12 pieces as an example, the basic method adopts 4 groups + 2 groups of blade cylinders 2-4-3 suction mode, and the 8 pieces on the left side of the blister box 6 are defined as the whole storage area, and the 4 pieces on the right side are defined as the sporadic storage area. The 2 groups of blade cylinders 2-4-3 suction mode only fills the sporadic storage area for use, and the injection molding box 5 fills the whole storage area first and then fills the sporadic storage area according to the 4 groups of plug-in panels 7. In this way, the least number of position points can be programmed to complete the cyclic box replacement of 6 boxes of full plug-in panels 7 injection boxes 5 to 5 boxes of blister boxes 6, which greatly reduces the number of programming lines, thereby increasing the storage capacity of the box replacement system points of more models of plug-in panels 7.

[0036] like Figure 11 As shown, the positioning mechanism 2-5 is composed of a blocking cylinder 2-5-1, a side push cylinder 2-5-2, and a corner clip 2-5-3. The blister box 6 and the injection molding box 5 are driven by the roller and supported by the blocking cylinder 2-5-1. The four corners or two sides are clamped and positioned by the side push cylinder 2-5-2 and the corner clip 2-5-3 to ensure the accuracy of the position of the plug-in panel 7 each time.

[0037] like Figure 8 As shown, the inspection station 3 is composed of a frame 5 3-1, a conveying roller 5 3-2, a three-way module 2 3-3, a visual module 3-4, an electrical control system 2 3-5, and a positioning mechanism 5 3-6. The positioning mechanism 5 3-6 clamps the blister box 6, and the three-way module 2 3-3 drives the visual module 3-4 to perform quality inspection on the plug-in panel 7 of the blister box 6. The qualified products are transported as a whole to the unloading module 4-3 of the unloading station 4, and the unqualified products are transported as a whole to the unloading module 4-2 of the unloading station 4.

[0038] The three-way module 1 2 - 3 and the three-way module 2 3 - 3 in this embodiment are both existing technologies, and move in three directions of X axis, Y axis and Z axis, which will not be described in detail here.

[0039] like Figure 8As shown, the visual module 3-4 includes a camera 3-4-1, a camera mounting assembly 3-4-2, a visual control module 3-4-3, and a circular light source 3-4-4. The camera mounting assembly 3-4-2 is provided with a consistent center distance. The images taken by the three cameras 3-4-1 under the circular light source 3-4-4 are spliced to obtain the image of the plug-in panel 7 at one time while meeting the detection accuracy. Compared with the detection efficiency of a single camera, it covers all the detection points at one time without the risk of missing items. The visual control module 3-4-3 communicates with the electrical control system 3-5. The visual control module 3-4-3 A detection request is issued, and the electrical control system 3-5 runs the corresponding program to test the plug-in panels 7 in groups. When the visual control module 3-4-3 outputs a qualified test result, it continues to run to the next group of corresponding position tests. When the qualified number reaches the number set by the electrical control system 3-5 program, the qualified plug-in panels 7 are transported to the offline module three 4-3 of the offline station 4 for automatic stacking. When the visual control module 3-4-3 outputs an unqualified test result, the unqualified plug-in panels 7 are transported to the offline module three 4-2 of the offline station 4 for automatic stacking to avoid line occupancy affecting the efficiency of the entire line.

[0040] like Figure 9-10 As shown, the offline workstation 4 includes an offline module 1 4-1, an offline module 2 4-2, and an offline module 3 4-3. The offline module 1 4-1 is used for automatic stacking and collection of the injection molding boxes 5, the offline module 2 4-2 is used for automatic stacking and collection of the blister boxes 6 of the unqualified plug-in panels 7, and the offline module 3 4-3 is used for automatic stacking and collection of the blister boxes of the qualified plug-in panels 7. Each module has independent functions, which is convenient for identification and operation, and automatic stacking and collection reduces labor input.

[0041] The offline module 1 4-1 includes a frame 6 4-1-1, a conveying roller 6 4-1-2, a positioning mechanism 6 4-1-3, a non-return mechanism 4-1-4, and a pneumatic lifting system 2 4-1-5. The conveying roller 6 4-1-2 conveys the injection molding box 5 to the right position, and the pneumatic lifting system 2 4-1-5 lifts the injection molding box 5 and separates it from the conveying roller 6 4-1-2. During the rising process of the pneumatic lifting system 2 4-1-5, the non-return mechanism 4-1-4 is squeezed and compressed back. When the pneumatic lifting system 2 4-1-5 rises to the upper plane of the non-return mechanism 4-1-4, the non-return mechanism 4-1-4 is squeezed and disappears, and the support returns to its original position to lift the injection molding box 5 to complete an automatic stacking and collection. The pneumatic lifting system 2 4-1-5 drops to the starting position. This offline module has a simple structure, low cost, low programming workload, and is easy to debug and maintain.

[0042] The plug-in panel 7 box replacement inspection work is carried out through the online module 1-1, the online module 2 1-2, the box changing station 2, the inspection station 3, the offline module 1 4-1, the offline module 2 4-2, and the offline module 3 4-3 modules. Specifically, the multi-layer empty blister box 6 is placed into the online module 2 1-2 along the positioning mechanism 2 1-2-3 by the composite robot, and the multi-layer injection molding box 5 filled with the plug-in panel 7 is placed into the online module 1-1 along the positioning mechanism 1-1-3. The work starts, the online module 2 1-2 splits a layer of blister box 6 to the conveying roller 2 1-2-2 and conveys it to the box changing station 2, the online module 1-1 splits a layer of injection molding box 5 to the conveying roller The delivery roller 1-1-2 is transported to the box changing station 2, and the positioning mechanism 2-5 of the box changing station 2 is clamped, and then the box changing process is carried out. According to the program logic, the three-way module 1 2-3 moves to the position of the first group of plug-in panels 7 above the injection box 5, and the Z axis drops to the set height. The transmission module 2-4-1 rotates to open the blade cylinder 2-4-3 to the spacing between the plug-in panels 7 of the injection box 5, and pushes out the vacuum suction cup 2-4-4 to adsorb the plug-in panel 7. After completion, the blade cylinder 2-4-3 is retracted, the Z axis of the three-way module 1 2-3 rises to its original position, and the XY axis moves to the first group of empty material positions of the blister box 6. The transmission module 2-4-1 runs again to open the blade cylinder 2-4-3 The cylinder 2-4-3 shrinks to the distance between the plug-in panel 7 of the blister box 6, the Z axis drops to the set height, the blade cylinder 2-4-3 is pushed out, the vacuum suction cup 2-4-4 is closed, and the plug-in panel 7 falls into the slot of the blister box 6; the above box changing process is repeated. When the plug-in panel 7 in the injection molding box 5 is emptied, the conveying roller four 2-2 conveys the empty injection molding box 5 to the position of the offline module one 4-1 for stacking. The empty injection molding boxes 5 are stacked to the maximum limit for recycling; when the slots of the plug-in panel 7 of the blister box 6 at the box changing station 2 are all full, the conveying roller four 2-2 conveys the blister box 6 filled with plug-in panel 7 to the inspection station 3, and the three-way module two 3-3 moves to the side of the blister box 6 Above the center of the four plug-in panels 7, the visual module 3-4 takes photos and matches the feature template to detect whether the processing, engraving content, etc. of the plug-in panels 7 are qualified. If four are qualified, the Y axis of the XYZ three-axis module moves horizontally to the next group of four plug-in panels 7 for photo inspection until all plug-in panels 7 are qualified. The conveying roller five 3-2 conveys the qualified plug-in panel 7 blister box 6 to the offline module three 4-3 for stacking of qualified products. If the visual module 3-4 detects that the plug-in panel 7 is unqualified, the three-axis module two 3-3 immediately returns to the origin, and the conveying roller five 3-2 conveys the unqualified plug-in panel 7 blister box 6 to the offline module two 4-2 for stacking of unqualified products. Example

[0043] The specific implementation method of this embodiment is that the plug-in panel automatic box changing device and detection system performs plug-in panel 7 detection work through the online module three 1-3, detection station 3, offline module two 4-2, and offline module three 4-3. Specifically, multiple layers of blister boxes 6 filled with plug-in panels 7 to be detected are placed into the online module three 1-3 clamping cylinder three 1-3-4 along the positioning mechanism three 1-3-3, and the work is started. The online module three 1-3 splits a layer of blister box 6 onto the conveying roller three 1-3-2, which is transported to the detection station 3 by the conveying roller three 1-3-2. The detection station 3 is the same as that of Example 1. If the detection is qualified, it is transported to the offline module three 4-3 for palletizing of qualified products. If the detection is unqualified, the unqualified plug-in panel 7 blister box 6 is transported to the offline module two 4-2 for palletizing of unqualified products. Example

[0044] The specific implementation method of this embodiment is that the plug-in panel automatic box changing device and detection system performs the box changing work of the 25-width plug-in panel 7 from the 10-piece slot injection box 5 to the 12-piece slot blister box 6 through the online module 1-1, the online module 2 1-2, the box changing station 2, and the offline module 3 4-3. Specifically, the composite robot places the multi-layer empty blister box 6 along the positioning mechanism 2 1-2-3 into the online module 2 1-2, and places the multi-layer injection box 5 filled with the plug-in panel 7 along the positioning mechanism 1-1-3 into the online module 1-1 to start working. The online module 2 1-2 splits a layer of blister box 6 to the conveyor roller. The second module 1-2-2 is transported to the box changing station 2, and the online module 1-1 splits a layer of injection molding box 5 to the conveying roller 1-1-2 and transports it to the box changing station 2. When it arrives at the box changing station 2, it is clamped at the positioning mechanism 2-5 position. According to the quick allocation method, the 10 plug-in panels 7 of the injection molding box 5 are defined as the first group of 4 pieces, the second group of 4 pieces, and the third group of 2 pieces. The 12 plug-in panels 7 of the blister box 6 are defined as the first group of 4 pieces, the second group of 4 pieces, the third group of 4 pieces or the third group of 2 pieces and the fourth group of 2 pieces. The first group of 4 pieces of the injection molding box 5 can be filled with the second group of 4 pieces and the third group of 4 pieces of the blister box 6, and the second group of 4 pieces of the injection molding box 5 can be filled with the blister box 6 The first group of 4 pieces and the second group of 4 pieces, the third group of 2 pieces of injection molding box 5 can be filled with the third group of 2 pieces and the fourth group of 2 pieces of blister box 6, and the boxes are changed according to the above distribution. After the first box of injection molding box 5 is empty, it goes to the offline module 4-1 for stacking. The first box of injection molding box 6 lacks the fourth group of 2 pieces. After the second box of injection molding box 5 is filled with the third component, the first box of injection molding box 6 plug-in panel 7 is full and goes to the offline module three 4-3. The second box of injection molding box 5 is empty. The second box of blister box 6 lacks the third group of 4 pieces. The first group of 4 pieces of the third box of injection molding box 5 is filled with the second box of blister box 6 and is full. Continue to fill the third box of blister box 6. The third box of injection molding box 5 is empty, and the third The blister box 6 lacks the second group of 4 pieces and the third group of 2 pieces. After the fourth injection box 5 is filled with the third blister box 6, the remaining second group of 4 pieces fills the empty slots of the first group of 4 pieces in the fourth blister box 5. The first group of 4 pieces and the second group of 4 pieces in the fifth injection box 5 fill the fourth blister box 6. The remaining third group of 2 pieces are put into the fourth group of 2 pieces in the fifth blister box. The sixth injection box 5 fills the remaining empty slots of the fifth blister box 6. This completes a set of cycles. Repeat the box changing operation according to the cycle. This method only requires setting 6 groups of interpolation motion points. If the sequential box changing method is used, more than 10 groups of points need to be set, and the filling method is chaotic. For other quantities of carrier material box changing, the slot allocation can be performed according to the above method to reduce the layout of the handling points and avoid algorithm complexity.
