The buffer assembly 53 is arranged between the first labeling head 51 and the second labeling head 52, and the buffer assembly 53 is used to connect the first labeling head 51 and the second labeling head 52. The buffer assembly 53 includes a buffer rod 531, a buffer cylinder 532 and a buffer spring 533. The buffer rod 531 is movably inserted in the buffer cylinder 532, and the buffer spring 533 is wound and connected to the outside of the buffer rod 531, and the two ends of the buffer spring 533 are respectively fixedly connected to the side wall of the buffer rod 531 and the outer side wall of the buffer cylinder 532. The structural design of the labeling head assembly 5 in the present invention is reasonable and has a buffering function. When the labeling head assembly 5 moves downward, it can avoid crushing the medicine box. Specifically, when the second labeling head 52 contacts the medicine box, as the driving assembly 6 continues to work, the first labeling head 51 will move relative to the second labeling head 52, avoiding the second labeling head 52 from having a downward movement, thereby protecting the medicine box.

[0035] In this embodiment, a residual detection mechanism 9 is provided in the labeling head assembly 5, and the residual detection mechanism 9 includes a contact detector 91 matched with the labeling part 8, and the contact detector 91 is movably arranged in a first movable groove 92, the first movable groove 92 is opened on the second labeling head 52, and the second labeling head 52 is provided with a second movable groove 93 matching the first movable groove 92, and a first guide support assembly 94 is provided in the second movable groove 93, and the two ends of the first guide support assembly 94 are respectively fixedly connected to the lower end surface of the contact detector 91 and the upper end surface of the first labeling head 51. The residual detection mechanism 9 provided in the present invention is used to detect the amount of labels in the labeling part 8. Specifically, during the buffering process of the labeling head assembly 5, when the first labeling head 51 moves toward the second labeling head 52, the contact detector 91 will be moved out of the first movable groove 92 through the first guide support assembly 94, so as to contact the labels in the labeling part 8, thereby detecting the label content in the labeling part 8 through the contact detector 91.

[0036] In this embodiment, the first guide support assembly 94 includes a first guide support rod 941, a first guide support tube 942 and a first guide support spring 943. The first guide support rod 941 is movably inserted in the first guide support tube 942, and the first guide support spring 943 is wrapped and connected to the outside of the first guide support rod 941, and the two ends of the first guide support spring 943 are respectively fixedly connected to the side wall of the first guide support rod 941 and the outer side wall of the first guide support tube 942. The setting of the first guide support assembly 94 can not only play a guiding and supporting role for the movement of the contact detector 91, but also provide power for the reset movement of the contact detector 91, and can also play a buffering role. Specifically, when the contact detector 91 contacts the label in the labeling part 8, it can avoid excessive squeezing of the label in the labeling part 8, thereby protecting the label in the labeling part 8.

[0037] In this embodiment, a prompt mechanism 10 is provided in the labeling head assembly 5, and the prompt mechanism 10 includes a prompter 101 provided on the second labeling head 52, and a support chute 102 provided on the side wall of the first movable groove 92, a first electrode contact 103 is movably provided in the support chute 102, and the first electrode contact 103 is fixedly provided on the side wall of the contact detector 91, and a second electrode contact 104 matching the first electrode contact 103 is fixedly connected in the support chute 102, wherein the second electrode contact 104 is close to the support chute. The top wall of the support slide 102 is provided with a prompt mechanism 10 provided in the present invention, which is used to remind the staff to replace the labels when the labels in the labeling part 8 are used up. Specifically, as the label content in the labeling part 8 is different, the distance that the contact detector 91 moves out of the first moving groove 92 is inconsistent under the state of friction. When the labels in the labeling part 8 are used up, the contact detector 91 will bring the first electrode contact 103 into contact with the second electrode contact 104, thereby connecting the series circuit, and the prompter 101 starts working to remind the staff that the labels in the labeling part 8 are used up.

[0038] In this embodiment, the labeling head assembly 5 is provided with an anti-contact mechanism 11, which includes a limiting groove 111 provided on the side wall of the first moving groove 92, and a limiting rod 112 movably plugged into the contact detector 91 and matching the limiting groove 111.

The contact plate 114 is movably arranged in the mounting groove 115, and the mounting groove 115 is provided on the first electrode contact piece 103. One end of a second guide support assembly 116 is fixedly connected to the lower end surface of the contact plate 114, and the other end of the second guide support assembly 116 is fixedly connected to the mounting groove 1 On the bottom wall of 15, the anti-contact mechanism 11 provided in the present invention is used to lock the contact detector 91 when the labels in the labeling part 8 are used up, thereby preventing the contact detector 91 from contacting the roller on which the labels are wound, causing wear of the equipment. Specifically, as the first electrode contact 103 moves toward the second electrode contact 104, the resistance of the second electrode contact 104 will cause the resistance plate 114 to move into the installation groove 115. The movement of the resistance plate 114 will push the limit rod 112 to the left through the push-pull rod 113. When the first electrode contact 103 contacts the second electrode contact 104, the limit rod 112 enters the limit groove 111, thereby locking the contact detector 91 in the first moving groove 92.

[0039] In this embodiment, the second guide support assembly 116 includes a second guide support rod 1161, a second guide support tube 1162 and a second guide support spring 1163. The second guide support rod 1161 is movably inserted in the second guide support tube 1162. The second guide support spring 1163 is wound around the outside of the second guide support rod 1161, and the two ends of the second guide support spring 1163 are respectively fixedly connected to the side wall of the second guide support rod 1161 and the outer side wall of the second guide support tube 1162. The setting of the second guide support assembly 116 can not only play a guiding support role for the movement of the contact plate 114, but also provide power for the reset movement of the contact plate 114.

[0040] Beneficial effects of the present invention:

[0041] The present invention improves the structure of the existing compound medicine cabinet medicine box. The improved compound medicine cabinet medicine box contains a combination structure of a shooting device 7 and a labeling part 8. The setting of the combination structure is used to attach a label to the medicine box during the process of dispensing the medicine, so as to provide the customer with the actual usage method and usage course of the medicine. When the medicine box moves to the bottom of the labeling head assembly 5, the information is collected by the shooting device 7 and transmitted to the external processor. The processor starts the driving assembly 6 and moves the labeling head assembly 5 downward to contact the medicine box. When contacting the medicine box, the labeling part 8 attaches a label to the medicine box to provide the customer with the actual usage method and usage course of the medicine.

[0042] The labeling head assembly 5 in the present invention has a reasonable structural design and a buffering function. When the labeling head assembly 5 moves downward, it can avoid crushing the medicine box. Specifically, when the second labeling head 52 contacts the medicine box, as the driving assembly 6 continues to work, the first labeling head 51 will move relative to the second labeling head 52, avoiding the second labeling head 52 from moving downward, thereby protecting the medicine box.

[0043] The remaining amount detection mechanism 9 provided in the present invention is used to detect the amount of labels in the labeling part 8. Specifically, during the buffering process of the labeling head assembly 5, when the first labeling head 51 moves toward the second labeling head 52, the contact detector 91 will be moved out of the first moving groove 92 through the first guide support assembly 94 to achieve contact with the labels in the labeling part 8, thereby detecting the label content in the labeling part 8 through the contact detector 91.

[0044] The reminder mechanism 10 provided in the present invention is used to remind the staff to replace the labels when the labels in the labeling part 8 are used up. Specifically, as the label content in the labeling part 8 is different, the distance that the contact detector 91 moves out of the first moving groove 92 in the state of conflict is inconsistent. When the labels in the labeling part 8 are used up, the contact detector 91 will bring the first electrode contact 103 into contact with the second electrode contact 104, thereby connecting the series circuit and the reminder 101 starts working to remind the staff that the labels in the labeling part 8 are used up.

[0045] The anti-contact mechanism 11 provided in the present invention is used to lock the contact detector 91 when the labels in the labeling part 8 are used up, thereby preventing the contact detector 91 from contacting the roller on which the labels are wound, causing wear of the equipment. Specifically, as the first electrode contact 103 moves toward the second electrode contact 104, the resistance of the second electrode contact 104 will cause the resistance plate 114 to move into the installation groove 115. The movement of the resistance plate 114 will push the limit rod 112 to the left through the push-pull rod 113. When the first electrode contact 103 contacts the second electrode contact 104, the limit rod 112 enters the limit groove 111, thereby locking the contact detector 91 in the first moving groove 92.
