[0105] As shown in the figure, Figure 15 The rotating module comprises a 180° rotating actuator 710 arranged on the frame, a second box supporting plate 711 arranged at the power output end of the 180° rotating actuator 710, and a photoelectric sensor for detecting the front and back of the packaging box. The photoelectric sensor is arranged corresponding to the gap of the forward packaging box on the second box supporting plate 711, and its signal output end is connected to the signal input end of the 180° rotating actuator 710 through the controller.

[0106] It should be noted that the "forward direction" of the packaging box refers to the tail end of the pre-filled glass product placed in the packaging box facing the feeding and discharging mechanism 3.

[0107] The second transfer module comprises a first rodless cylinder 712 arranged on the frame and a first box pushing block 713 arranged at the power output end of the first rodless cylinder 712.

[0108] In actual operation, the horizontal conveying belt 701 transports the stacked packaging boxes containing semi-finished products to the first tray plate, while the limiting baffle plates 706 on both sides of the first tray plate adjust the position under the control of the fifth cylinder 705 to ensure that the packaging boxes are limited as a whole on the first tray plate; then the first toothed belt type electric cylinder 707 in the first transfer module controls the sixth cylinder 708 and the vacuum suction cup 709 to suck a single packaging box and transfer it to the second tray plate 711 (every time a packaging box is taken away, the belt-driven linear actuator 704 in the lifting assembly 702 controls the first tray plate to rise by one box height); then the photoelectric sensor in the rotating module detects the notch position on the second tray plate 711, and then judges whether to control the 180° rotating actuator 710 to act, so that the packaging box on the second tray plate 711 is always "forward"; finally, the first rodless cylinder 712 in the second transfer module pushes the packaging box to the second material conveying assembly 13 through the first box pushing block 713.

[0109] It should be noted that the semi-finished product refers to a pre-filled glass product to be inserted with a needle, and the finished product refers to a pre-filled glass product with a needle inserted.

[0113] In actual operation, the first box pushing module controls the packaging boxes containing semi-finished products to gradually pass through the feeding station in an intermittent progressive manner from the bottom, during which the feeding and unloading mechanism 3 can transfer the semi-finished products of the packaging boxes to the needle inserting mechanism 1; then the second box pushing module controls the empty packaging boxes to be gradually transported to the unloading station in an intermittent progressive manner from the top, and the box pushing assembly at the unloading station takes over and controls the empty packaging boxes to pass through the unloading station.

[0114] (3) Third material conveying assembly 14

[0115] The third material conveying assembly 14 is used for storing and stacking the packaging boxes containing finished products. The structure of the third material conveying assembly 14 is the same as that of the first material conveying assembly 12, and thus is not described again.

[0116] III. Feeding and discharging mechanism 3

[0117] The feeding and discharging mechanism 3 includes a feeding assembly 15 arranged on the rack at a feeding station for transferring the pre-filled glass products from the material conveying mechanism 2 to the needle loading mechanism 1, and a discharging assembly 16 arranged on the rack at a discharging station for transferring the pre-filled glass products from the needle loading mechanism 1 to the material conveying mechanism 2.

[0118] The feeding assembly 15 and the discharging assembly 16 have the same structure, as shown in Figure 17 and Figure 18 including a 90° rotating assembly, an opening and closing assembly, and a mechanical hand assembly arranged on the rack;

[0119] The 90° rotating assembly includes a rotating motor 901 arranged on the rack, a fourth cylinder 902 arranged on the power output end of the rotating motor 901, and two bottle holding rods arranged on the power output end of the fourth cylinder 902. In the horizontal state, the bottle holding rods correspond to the pre-filled glass products on the material conveying mechanism 2, and in the vertical state, the bottle holding rods correspond to the working end of the mechanical hand assembly.

[0120] The opening and closing assembly includes a vertical cylinder 903 arranged on the rack, a horizontal cylinder 904 arranged on the power output end of the vertical cylinder 903, a first bottle holding rod arranged on the power output end of the horizontal cylinder 904, and a second bottle holding rod arranged on the power output end of the vertical cylinder 903; the first bottle holding rod is consistent in height with the second bottle holding rod.

[0121] The mechanical hand assembly includes a first grabbing mechanical hand 905, a second grabbing mechanical hand 906, and a third grabbing mechanical hand 907 arranged in linkage; the first grabbing mechanical hand 905 is provided with a double-slot clamping jaw block, and the distance between the two clamping slots of the double-slot clamping jaw block is equal to the distance between the two bottle holding rods on the fourth cylinder 902; the second grabbing mechanical hand 906 and the third grabbing mechanical hand 907 are provided with a single-slot clamping jaw block, and the distance between the single-slot clamping jaw blocks on the second grabbing mechanical hand 906 and the third grabbing mechanical hand 907 is equal to the distance between the adjacent two bottle holding rods 105 on the equal division disc 101.

[0122] In actual operation, the rotating motor 901 in the 90° rotating assembly drives the fourth cylinder 902 and the bottle supporting rod to the horizontal state, aligns with the tail of the semi-finished product in the packaging box at the feeding station, and the fourth cylinder 902 drives the bottle supporting rod to extend into the semi-finished product from the tail; then the rotating motor 901 drives the fourth cylinder 902 and the bottle supporting rod to carry the semi-finished product to the vertical state; the first grabbing manipulator 905 in the manipulator assembly grabs the semi-finished product by means of the double-slot jaw block and transfers it to the first bottle supporting rod and the second bottle supporting rod of the opening and closing assembly (at this time, the distance between the first bottle supporting rod and the second bottle supporting rod is equal to the distance between the two clamping grooves in the double-slot jaw block); then the horizontal cylinder 904 in the opening and closing assembly controls the first bottle supporting rod to move away from the second bottle supporting rod until the distance between them is equal to the distance between the two single-slot jaw blocks; finally, the second grabbing manipulator 906 and the third grabbing manipulator 907 grab the corresponding semi-finished products by means of the single-slot jaw blocks and transfer them to the bottle supporting rod 105 of the equal division disc 101.

[0123] It should be noted that, in order to prevent the semi-finished product from being thrown off the bottle supporting rod when the rotating motor 901 drives the fourth cylinder 902 and the bottle supporting rod to rotate, in this embodiment, a plurality of arc-shaped protective plates are provided at the feeding station and the discharging station corresponding to the box conveying platform 801, to form an arc-shaped guide groove for limiting the semi-finished product, so that it can be smoothly changed from the horizontal state to the vertical state under the driving of the rotating motor 901.

[0124] This embodiment carries out the production of "needle assembly" under the control of the controller, and the working process is as follows:

[0125] The packaging boxes stacked with semi-finished products are input into the material conveying mechanism 2, and the first material conveying assembly 12 in the material conveying mechanism 2 acts to transfer the packaging boxes one by one to the second material conveying assembly 13 in the "forward" state; the second material conveying assembly 13 controls the packaging boxes to gradually pass through the feeding station in an intermittent progressive manner, and during this period, the feeding assembly 15 in the feeding and discharging mechanism 3 transfers the semi-finished products in the packaging boxes to the needle assembling mechanism 1 in the manner of "two by two in a group"; after the semi-finished products in the packaging boxes are transferred, the second material conveying assembly 13 controls the empty packaging boxes to gradually pass through the discharging station in an intermittent progressive manner.

[0126] The aliquot disc 101 in the process disc assembly 4 of the needle mounting mechanism 1 rotates under the driving of the direct drive motor, and carries the semi-finished product on the bottle supporting rod 105 to transfer between each station of the needle mounting mechanism 1, in sequence: reaching the needle inserting station, inserting the steel needle for injection into the needle head position of the semi-finished product through the needle inserting assembly 5; reaching the preheating station, preheating and drying the needle head of the semi-finished product through the heater assembly 6; reaching the dispensing station, injecting an appropriate amount of UV glue into the needle head of the semi-finished product through the dispensing machine assembly 7; reaching the ultraviolet irradiation station, irradiating to solidify the UV glue through the baking lamp assembly 8; reaching the test station, applying an upward pulling force to the steel needle at the needle head of the semi-finished product through the tensile test assembly 9; reaching the detection station, detecting the insertion state of the steel needle at the needle head of the semi-finished product through the quality detection assembly 10; reaching the kick-out station, removing unqualified products through the kick-out assembly 11; and finally, the finished product reaches the unloading station.

[0127] At the unloading station, the unloading assembly 16 in the unloading assembly 16 transfers the finished product on the bottle supporting rod 105 on the aliquot disc 101 into the empty packaging box in the second material conveying assembly 13 in the manner of “two by two”; after being filled with finished products, the second material conveying assembly 13 transfers the packaging box to the third material conveying assembly 14, and the third material conveying assembly 14 outputs the stacked packaging boxes containing finished products after stacking.
