[0190] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0191] Unless otherwise defined, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specific implementation methods are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the terms "including" and "having" in the specification and claims of the present invention and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0192] In the description of the specific implementation methods of the present invention, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present invention, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0193] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments.

[0194] In the description of the embodiments of the present invention, the term "and / or" is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in the present invention generally indicates that the associated objects before and after are in an "or" relationship.

[0195] Throughout the present invention, numerical values ​​represent approximate measures or limits of ranges to cover minor deviations from given values ​​as well as embodiments with about the values ​​mentioned and embodiments with the exact values ​​mentioned. Except for the working examples provided at the end of the detailed description, all numerical values ​​of parameters (e.g., amounts or conditions) in this specification (including the appended claims) should be understood to be modified by the term "about" in all cases, regardless of whether "about" actually appears before the numerical value. "About" indicates that the stated numerical value allows some minor imprecision (close to the exact value of the value to some extent; approximately or reasonably close to the value; almost). If the imprecision provided by "about" is not otherwise understood in this ordinary sense in the art, "about" as used in the present invention at least indicates the variation that can be produced by the ordinary methods of measuring and using such parameters. For example, "about" may include a variation of less than or equal to 5%, optionally less than or equal to 4%, optionally less than or equal to 3%, optionally less than or equal to 2%, optionally less than or equal to 1%, optionally less than or equal to 0.5%, and in some aspects, optionally less than or equal to 0.1%.

[0196] Additionally, disclosure of ranges includes disclosure of all values ​​within the entire range and further divided ranges, including endpoints and sub-ranges given for such ranges.

[0197] The embodiments of the present invention will be described in more detail below by way of examples. It should be noted that the embodiments of the present invention are not limited to these examples.

[0198] Example

[0199] In a specific embodiment, Figure 1-8 As shown, a rotary rod labeling device includes a frame 1, a main body 2, a torque detection component 3, a rotating syringe component 4, a syringe feed track 5, a push rod feed track 6, a feed dial wheel component 7, an over-rotation detection component 8, a syringe outlet dial wheel component 9, a finished product track 10, a waste track 11, a rejection box component 12, a camera assembly 13, a main power mechanism 14, a high-precision labeling head 15 and a label pressing mechanism 16.

[0200] In this embodiment, a main body 2 is installed on the platform near the middle of the frame 1, and the main body 2 is used to assemble the syringe and the push rod at high speed;

[0201] The label pressing assembly is on one side of the main body 2 and is used to label the syringe;

[0202] The rotating needle cylinder assembly 4 is located at the inlet side of the main body 2, specifically near the needle cylinder inlet and the push rod inlet, and its function is to provide friction force for the relative rotation of the needle cylinder and the push rod.

[0203] The syringe feed track 5 is at the syringe entrance of the feed thumbwheel assembly 7 and is used for syringe loading.

[0204] The push rod feed track 6 is at the push rod entrance of the feed thumbwheel assembly 7 and is used for push rod loading.

[0205] The feed thumbwheel assembly 7 is located at one side of the main body 2 and is used to feed the syringe and the push rod into the main body 2 for high-speed assembly.

[0206] The syringe outlet thumbwheel assembly 9 is arranged at the outlet side of the main body 2, specifically near the outlet of the assembled syringe, and its function is to deliver the assembled syringe.

[0207] The finished product track 10 is arranged at the finished product outlet of the syringe thumbwheel assembly 9 , the waste track 11 is arranged at the waste outlet of the syringe thumbwheel assembly 9 , and the reject box assembly 12 is arranged at the outlet of the waste track 11 .

[0208] The over-rotation detection component 8 is near the syringe output thumbwheel component 9. Its function is to detect whether the assembled syringe is over-rotated. Once over-rotated, it means that the syringe is damaged and the syringe must be sent to the waste track 11. The waste is moved from the waste track 11 to the rejection box to wait for processing; and the products that have not been over-rotated are sent to the finished product track 10.

[0209] The camera assembly 13 is arranged on a platform near the middle of the frame 1, and its function is to detect whether the label on the syringe is properly affixed.

[0210] The main power mechanism 14 is located below the platform of the frame 1 near the middle, and its function is to provide power to various components of the main body 2.

[0211] The main body 2 has a syringe entrance and a push rod entrance. The syringe entrance is connected to the rotating syringe assembly 4, and the push rod entrance is connected to the push rod track 6. The syringe entrance is located below the push rod entrance. The feed dial assembly 7 sends the syringe to the syringe entrance and also sends the push rod to the push rod entrance position.

[0212] The specific application of this embodiment is as follows:

[0213] The feed thumbwheel assembly 7 sends the syringe arranged on the syringe feed track 5 and the push rod arranged on the push rod feed track 6 to the syringe entrance below the main body 2 and the push rod entrance above the main body 2 respectively. After the syringe and the push rod enter the main body 2, they rotate relative to each other under the action of the syringe rotating assembly 4, and the push rod is screwed into the syringe to realize high-speed assembly. After the assembly is completed, the product first passes through the inspection station of the torque detection assembly 3. The torque detection assembly 3 detects whether the product is assembled in place. If it is assembled in place, it enters the next station. If it is not assembled in place, the torque detection assembly 3 supplements it with appropriate torque. Next, the product comes to the product outlet station on the main body 2, and the syringe outlet thumbwheel assembly 9 provides the power for product discharge. Among them, the over-rotation detection assembly 8 is used to detect whether the product is over-rotated. If it is over-rotated, the syringe outlet thumbwheel assembly 9 sends the product to the waste track, and finally flows to the rejection box assembly 12. If it is not over-rotated, the syringe outlet thumbwheel assembly 9 sends the product to the finished product track 10.

[0216] One end of the rocker arm tension spring 15-1-4-4 is fixed to the rocker arm tension spring fixing column 15-1-4-5, and the other end is connected to the swing plate 15-1-4-3. The swing roller 15-1-4-1 is swingably arranged at one end of the swing plate 15-1-4-3.

[0217] The swing roller 15-1-4-1 is tightened by the rocker spring 15-1-4-4. Its first function is to cooperate with the auxiliary roller 15-1-4-2 to tighten the label paper. In addition, since one end of the rocker spring 15-1-4-4 is fixed and the other end is not fixed, the swing roller 15-1-4-1 can swing left and right. In this way, when the two servo motors move, the instantaneous change in tension on the label paper will act on the swing roller 15-1-4-1, and the swing of the swing roller 15-1-4-1 will cause a slight change in the tension of the label paper, so that the tension on the label paper will change within a certain range. Such a buffer can ensure that the label paper will not break due to excessive instantaneous tension changes.

[0218] The paper receiving buffer 15-1-9 is arranged on one side of the paper receiving mechanism 15-1-10; the structure of the paper receiving buffer 15-1-9 is similar to the paper feeding buffer structure.

[0219] The first detection mechanism 15-1-5 is disposed between the thermal transfer unit 15-3 and the label supply mechanism 15-1-3; the first detection mechanism 15-1-5 is used to detect the moving distance of the label provided by the label supply mechanism 15-1-3.

[0223] The adjustment hand wheel 15-1-12-1 is fixed to the first end of the first adjustment screw 15-1-12-6, the second end of the first adjustment screw 15-1-12-6 is fixed to the first end of the lifting fixed seat 15-1-12-7, the first adjustment screw 15-1-12-6 passes through the lifting adjustment seat 15-1-12-3 and the lifting slide 15-1-12-5, and the first end of the lifting slide rod 15-1-12-4 is fixed to the lifting adjustment seat 1 The lower end of 5-1-12-3, the second end of the lifting slide rod 15-1-12-4 is fixed to the first end of the lifting fixed seat 15-1-12-7, the lifting slide seat 15-1-12-5 is slidably mounted on the lifting slide rod 15-1-12-4, and the rectangular tooth rod 15-1-12-8 is fixed to the second end of the lifting fixed seat 15-1-12-7 through a rectangular nut 15-1-12-9 and a washer 15-1-12-10;

[0224] The adjustment mechanism 15-1-12 is used to adjust the height of the rotary rod labeling unit 15-1. The specific adjustment process is:

[0225] Turn the adjustment hand wheel 15-1-12-1, the first adjustment screw 15-1-12-6 rotates, and the lifting slide 15-1-12-5 is driven to move on the lifting slide rod 15-1-12-4 through the thread transmission, and the height of the rectangular tooth rod 15-1-12-8 is adjusted on the other side, so that the lifting fixed seat 15-1-12-7 is lifted and lowered. The lifting and lowering of the lifting fixed seat 15-1-12-7 is the lifting and lowering of the rotary rod labeling unit.

[0226] like Fig.13 As shown, the push-pull adjustment head unit 15-2 includes a first five-star knob 15-2-1, a second digital display 15-2-2, a second adjustment screw 15-2-3, a main engine adjustment seat 15-2-4, a chrome-plated rod 15-2-5 and a thrust ball bearing 15-2-6; the first five-star knob 15-2-1 is arranged at the first end of the second adjustment screw 15-2-3, the thrust ball bearing 15-2-6 is arranged at the second end of the second adjustment screw 15-2-3, the chrome-plated rod 15-2-5 is arranged parallel to the second adjustment screw 15-2-3, the main engine adjustment seat 15-2-4 is slidably arranged on the chrome-plated rod 15-2-5, and the bottom of the main engine adjustment seat 15-2-4 is provided with a thread that cooperates with the second adjustment screw 15-2-3;

[0227] The push-pull adjustment head unit 15-2 is used to adjust and fix the position of the rotary rod labeling unit 15-1. The specific adjustment process is: turn the first five-star knob 15-2-1 to drive the second adjustment screw 15-2-3 to rotate, and drive the main machine adjustment seat 15-2-4 to slide on the chrome-plated rod 15-2-5 through thread transmission, thereby realizing the position adjustment of the rotary rod labeling unit 15-1.

[0228] like Fig.14 As shown, the thermal transfer unit 15-3 includes a second five-star knob 15-3-1, a third digital display 15-3-2, a third adjustment screw 15-3-3, a first slide bar 15-3-4, a plane slide 15-3-5, a third five-star knob 15-3-6, a fourth digital display 15-3-7, a vertical slide 15-3-8, a fourth adjustment screw 15-3-9, a fixed base 15-3-10, and a second slide bar 15-3-11;

[0229] The planar slide 15-3-5 is slidably arranged on the first slide bar 15-3-4, the third adjusting screw 15-3-3 passes through the planar slide 15-3-5, and the planar slide 15-3-5 is provided with a thread cooperating with the third adjusting screw 15-3-3, the second five-star knob 15-3-1 is arranged on one end of the third adjusting screw 15-3-3, the fixed base 15-3-10 is fixed on the planar slide 15-3-5, the second slide bar 15-3-11 is fixed on the planar slide 15-3-5, the vertical slide 15-3-8 is slidably mounted on the second slide bar 15-3-11, one end of the fourth adjusting screw 15-3-9 is fixed on the fixed base 15-3-10, and the other end is connected to the third five-star knob 15-3-6, and the third digital display 15-3-2 is mounted on the fourth adjusting screw 15-3-9.

[0230] The position of the thermal transfer unit 15-3 is adjusted as follows:

[0231] By turning the second five-star knob 15-3-1, the third adjusting screw 15-3-3 drives the plane slide 15-3-5 to slide on the first slide bar 15-3-4, thereby realizing plane movement; by turning the third five-star knob 15-3-6, the fourth adjusting screw 15-3-9 drives the vertical slide 15-3-8 to slide on the second slide bar 15-3-11, thereby realizing vertical movement.

[0232] In this embodiment, the first digital display, the second digital display, the third digital display and the fourth digital display are all used to display the pitch change.

[0233] The specific working process of the high-precision labeling head 15 is as follows:

[0234] The label on the paper supply tray 15-1-1 is wound around the brake mechanism 15-1-2 to the label supply mechanism 15-1-3. The label supply mechanism 15-1-3 is directly connected to the diamond grinding wheel by a servo motor, and there is a rubber wheel next to it to squeeze and generate friction to drive the label forward. When the label moves more or less, the label supply buffer 15-1-4 is adjusted. The label supply buffer 15-1-4 consists of plastic rollers and springs. When the label passes through the first detection mechanism 15-1-5, the moving distance is read and it continues to move forward. When it reaches the thermal transfer unit 15-3, the information is printed on the label. When it reaches the second detection mechanism 15-1-6, the moving distance of the label is read again. Finally, the label is peeled off and attached to the material through the peeling plate 15-1-7. When it senses that the material has reached the labeling station, the label pulling mechanism 15-1-8 pulls the label so that the label is detached from the peeling plate 15-1-7. The labeled backing paper goes to the paper receiving buffer 15-1-9, and its mechanism is composed of linear guides. When the bottom paper on the paper receiving buffer 15-1-9 reaches a certain amount, the paper receiving mechanism 15-1-10 starts to work to receive the paper. The paper receiving mechanism 15-1-10 is composed of a servo motor directly connected to a turntable. When there is no label on the paper supply tray 15-1-1, the inventory photoelectric 15-1-11 will alarm and stop.

[0235] When the material arrives, the label pulling mechanism 15-1-8 and the label supply mechanism 15-1-3 work simultaneously to ensure the label movement accuracy and make the labeling accuracy higher. The label pulling mechanism 15-1-8 and the label supply mechanism 15-1-3 are both composed of a servo motor directly connected to a diamond grinding wheel for rotation, and a rubber wheel is squeezed beside them.

[0236] In addition, this embodiment sets air passages in the syringe feed track 5 and the push rod feed track 6. On the one hand, the loading position of the syringe and the push rod is adjusted when loading, so as to prevent damage to the syringe caused by the wrong position during loading. On the other hand, additional power is applied to the syringe and the push rod, so as to improve the smoothness of the loading of the syringe and the push rod. Moreover, when the push rod and the syringe are delivered to the last batch, even if the gravity of the syringe or the push rod itself is not enough to completely deliver all the push rods and the syringe to the feed dial assembly 7, the air holes on both sides can well complete the final loading process, ensuring that each batch of syringes and push rods can be completely assembled. Since the arrangement of the air holes in the push rod feed track 6 is basically the same as that of the syringe feed track 5, this embodiment only takes the push rod feed track 6 as an example.

[0237] like Fig.15As shown, the inner wall of the feed push rod track 6 is provided with a plurality of air holes 6-1; the air holes 6-1 are connected to an external air source. The air holes 6-1 are provided on both sides of the inner wall of the feed push rod track 6. The air holes 6-1 are inclined. The air holes 6-1 are inclined downward; the air flow direction of the air holes 6-1 is from top to bottom and blows toward the feed thumbwheel assembly 7. The air holes 6-1 are provided symmetrically on both sides. The air holes 6-1 on one side are arranged in double rows. The air holes 6-1 on one side are arranged in seven on the top and three on the bottom. The feed thumbwheel assembly 7 is a disc-shaped structure, and the feed thumbwheel assembly 7 is provided with a plurality of product feeding grooves evenly arranged along the circumferential direction.

[0238] The specific application process of this embodiment is as follows:

[0239] The push rod enters the push rod track 6, and the push rod slides down on the push rod track 6 by its own gravity and the pressure of the subsequent push rod, and then enters the feed thumbwheel assembly 7, wherein the external air source is controlled by the controller, and the airflow is delivered to the push rod through the air holes 6-1 on both sides of the push rod track 6 to provide auxiliary feeding power. The screw rod device has a certain production rhythm, so the rotation of the feed thumbwheel assembly 7 is also intermittent, and the airflow delivered to the air hole 6-1 by the external air source is also indirectly delivered. In addition, since in the initial feeding stage of the push rod, the pressure of the subsequent push rod is sufficient to send the push rod into the feed thumbwheel assembly 7, the airflow provided by the external air source at this moment is relatively small, mainly to adjust the position of the push rod in the push rod track 6, and when the push rod is about to enter the feed thumbwheel assembly 7, the subsequent push rods are getting fewer and fewer, and the pressure on the push rod about to enter the feed thumbwheel assembly 7 is also getting smaller and smaller. At this time, the air supply of the external air source should be increased. The specific air supply parameters can be debugged accordingly in the controller according to the different push rods.

[0240] In this embodiment, the main body 2 includes a conjugate clamping jaw unit, such as Figure 16-Figure 17As shown, the conjugate jaw unit includes a fixed seat 2-4, a torsion spring assembly 2-3, and a conjugate jaw; the torsion spring assembly 2-3 is at least partially arranged on the upper end surface of the fixed seat 2-4, and the conjugate jaw is arranged on the lower end surface of the fixed seat 2-4; the conjugate jaw includes an active jaw 2-1, a passive jaw 2-2, a cam roller and a roller groove; the roller groove is arranged at the tail end of the passive jaw 2-2; the cam roller is arranged at the tail end of the active jaw 2-1 and passes through the roller groove; the active jaw 2-1 and the passive jaw 2-2 are connected by the cam roller; the active jaw 2-1 is provided with a latch tooth on one side close to the passive jaw 2-2, and the passive jaw 2-2 is provided with a push rod notch on one side close to the active jaw 2-1; the active jaw 2-1 and the passive jaw 2-2 are provided with an axial hole connected to the torsion spring assembly 2-3. The roller groove and the passive jaw 2-2 are an integral structure. The cam roller and the active jaw 2-1 are integrally formed. The torsion spring assembly 2-3 includes a torsion spring 2-3-1, a bearing roller 2-3-2, an active shaft 2-3-3 and a passive shaft 2-3-4; the torsion spring 2-3-1 is fixedly connected to the lower end of the bearing roller 2-3-2, and the torsion spring 2-3-1 is sleeved on the active shaft 2-3-3; the active shaft 2-3-3 passes through the fixed seat 2-4 and is fixedly connected to the active clamp 2-1; the passive shaft 2-3-4 passes through the fixed seat 2-4 and is fixedly connected to the passive clamp 2-2.

[0241] In this embodiment, the bearing roller 2-3-2 is used to twist the torsion spring 2-3-1 to provide the torque for opening the conjugate jaws. When not under force, the torsion spring 2-3-1 transmits the torque to the active jaw 2-1 through the active shaft 2-3-3, and the active jaw 2-1 transmits the force to the passive jaw 2-2 through the cam roller, thereby achieving stable closure under normal conditions. When it is necessary to open, the external power source transmits the torque to the torsion spring 2-3-1 through the bearing roller 2-3-2, and the torsion spring 2-3-1 twists, driving the active shaft 2-3-3 to rotate, and the force on the active jaw 2-1 changes. The passive jaw 2-2 and the active jaw 2-1 achieve conjugate opening and closing with the cooperation of the cam roller and the roller groove. In this embodiment, the latching teeth on the active jaw 2-1 have the function of preventing two-way rotation, which helps to tighten the thread during assembly. It has a simple structure, no gap in opening and closing, and high assembly precision.

[0242] like Figure 18-20 As shown, the rotating needle cylinder assembly 4 includes a synchronous belt 4-1, a first tension spring 4-2, a tension pressure sensor 4-3, a fan plate adjusting wheel 4-4, a first servo motor 4-5, a lead screw 4-6, a linear guide 4-7, a fan plate 4-8, a driving wheel 4-9, a driven wheel 4-10, a second servo motor 4-11 and an upper cover plate 4-12;

[0243] The synchronous belt 4-1 is wound around the driving wheel 4-9, the driven wheel 4-10 and the fan-shaped plate adjusting wheel 4-4;

[0244] The output shaft of the first servo motor 4-5 is connected to the screw 4-6, the screw 4-6 is connected to the linear guide 4-7, the linear guide 4-7 is connected to the first end of the first tension spring 4-2, the second end of the first tension spring 4-2 is fixed on the fan plate 4-8, the fan plate 4-8 is fixed by the fan plate adjusting wheel 4-4, the tension pressure sensor 4-3 is fixed at the connection between the first tension spring 4-2 and the linear guide 4-7, and the output shaft of the second servo motor 4-11 is connected to the driving wheel 4-9.

[0245] The tension and pressure sensor 4 - 3 is a digital sensor.

[0246] The tension and pressure sensor 4 - 3 is wirelessly connected to the display device.

[0247] In this embodiment, the upper cover plate 4-12 is used to hide components such as the synchronous belt 4-1, the driving wheel 4-9, the fan plate 4-8, etc., to provide dustproof and protective functions.

[0248] In specific applications, the host 2 screws the thread of the push rod into the syringe. In this embodiment, the syringe rotates, and the push rod is fixed in one direction and does not rotate. It is screwed in with the same rotation direction as the push rod thread. According to the different number of turns of the thread, the corresponding number of turns can be digitally set.

[0249] The feed thumbwheel assembly 7 sends the syringe and the push rod to the assembly station on the main machine 2. The synchronous belt 4-1 contacts the glass surface of the syringe, generating friction, which forms a torque to screw the push rod in. The friction depends on the tension of the first tension spring 4-2 that tightens the synchronous belt 4-1. The thread meshing and clearance between the push rod and the rubber plug in the syringe from different manufacturers are different, so the tightening torque is different. Therefore, during production, in order to ensure that it does not over-rotate, the tension of the first tension spring 4-2 is adjusted so that the synchronous belt 4-1 and the glass surface of the syringe are tightened to prevent slipping due to over-pressure, which can effectively ensure that it does not over-rotate.

[0250] The tension adjustment of the first tension spring 4-2 is provided with a digital tension pressure sensor 4-3, which can be displayed and adjusted on a display device.

[0251] In this embodiment, the synchronous belt 4-1 is flexible and is tensioned by the first tension spring 4-2. It is always close to the circumference of each roller and surrounds the syringe. Due to the effect of friction, the contact can always be guaranteed and the rotary rod can be rotated with a controllable number of turns.

[0252] The automatic tensioning of the synchronous belt 4-1 is achieved by swinging and tensioning the fan-shaped plate adjusting wheel 4-4, which has good mechanical properties and high efficiency.

[0253] The tension of the assembly is adjusted by the length of the first tension spring 4-2, and the adjustment is achieved by the first servo motor 4-5 rotating the lead screw 4-6, so that the lead screw 4-6 slides along the linear guide rail 4-7 to adjust the length of the first tension spring 4-2.

[0254] like Figure 21-22As shown, the torque detection assembly 3 includes a rotating bottle rubber wheel 3-1, a rotating sleeve 3-2, a rotating shaft 3-3, a rotating shaft center, a second fixing member 3-10, a third servo motor 3-7, a first coupling 3-6 and a second tension spring 3-8.

[0255] The rotating sleeve 3-2 is sleeved on the rotating shaft 3-3, and the rotating bottle rubber wheel 3-1 is arranged on the upper end of the rotating shaft 3-3.

[0256] The rotating shaft 3-3 and the rotating sleeve 3-2 are coaxially arranged on the upper surface of the second fixing member 3-10, the lower end of the rotating shaft 3-3 is connected to the third servo motor 3-7 through the first coupling 3-6, the third servo motor 3-7 is fixed to the lower end of the second fixing member 3-10, the second tension spring 3-8 is fixed to the side of the second fixing member 3-10, and the center sleeve of the rotating shaft is arranged on the sleeve.

[0257] The center of the rotating shaft includes a rotating seat 3-5 and a support shaft 3-4.

[0258] The support shaft 3-4 is fixed on the rotating seat 3-5 and passes through the rotating shaft 3-3.

[0259] This embodiment also includes a limit screw 3-9; the limit screw 3-9 is fixed to the upper section of the rotating shaft 3-3.

[0260] This embodiment also includes a positioning member 3-11, and the positioning member 3-11 is used to fix one end of the second tension spring 3-8.

[0261] In this embodiment, the third servo motor 3-7 is used to provide the torque detection component 3 with the power of the rotational force compensation, and the first coupling 3-6 is connected to the rotating shaft 3-3 to realize the torque transmission. When the third servo motor 3-7 outputs, the first coupling 3-6 transmits the torque to the rotating shaft 3-3. At this time, the torque detection component 3 rotates with the center of the rotating shaft as the rotation center. During the rotation, the rotating bottle rubber wheel 3-1 located at the upper end of the rotating shaft 3-3 rotates along. When the syringe 17 from the assembly station to the torque compensation station passes through the rotating bottle rubber wheel 3-1, it will slightly squeeze the rotating bottle rubber wheel 3-1 outward. Since the rotating bottle rubber wheel 3-1 rotates at all times, coupled with the material of the rotating bottle rubber wheel 3-1 itself, the syringe 17 will generate a relative friction force with the rotating bottle rubber wheel 3-1 when passing through the torque compensation station, and the syringe 17 that has not been screwed into place will continue to be screwed under the action of the rotating bottle rubber wheel 3-1. When the preset screwing value is reached, due to the tension of the second tension spring 3-8 and the position of the rotating bottle rubber wheel 3-1 relative to the limit screw 3-9, the syringe 17 screwed into place will not continue to be screwed at the torque compensation station, thereby ensuring that the syringe 17 will not be over-rotated.

[0262] In this embodiment, the torque is adjusted by adjusting the tension of the second tension spring 3-8. According to the specifications of the syringe, the tension of the second tension spring 3-8 and the length of the limit screw 3-9 are adjusted to adjust the distance between the rotating bottle rubber wheel 3-1 and the main machine 2, so as to achieve the torque setting of the torque compensation for the syringes of different specifications, thereby improving the adaptability of the torque detection component 3.

[0263] In this embodiment, the function of the limit screw 3-9 is to adjust the distance between the torque detection component 3 and the main body 2. One of the functions is to prevent the bottle rotating rubber wheel 3-1 above the torque detection component 3 from being too close or too far from the main body 2. If it is too close, the syringe 17 will be squeezed too hard when passing between the bottle rotating rubber wheel 3-1 and the main body 2, and the bottle will be broken. If it is too far, the friction between the syringe 17 and the bottle rotating rubber wheel 3-1 will be reduced, so that the label cannot be compacted.

[0264] like Figure 23-24 As shown, the label pressing mechanism 16 includes a main frame 16-11, a fourth servo motor 16-1, a main shaft 16-3, a second coupling 16-2, a first synchronous pulley 16-4, a first synchronous belt 16-5, a second synchronous pulley 16-6, a third synchronous pulley 16-7, a second synchronous belt 16-8, a rubber limit block 16-9 and a swing cylinder 16-10.

[0265] The fourth servo motor 16-1 is arranged at the lower part of the main frame 16-11, the fourth servo motor 16-1 is connected to the main shaft 16-3, the main shaft 16-3 is connected to the first synchronous pulley 16-4, the first synchronous pulley 16-4 is connected to the second synchronous pulley 16-6 through the first synchronous belt 16-5, the second synchronous pulley 16-6 is coaxially connected to the third synchronous pulley 16-7, and the second synchronous belt 16-8 is wound around the third synchronous pulley 16-7; the second synchronous belt 16-8 is arranged on one side of the main machine 2.

[0266] The swing cylinder 16-10 is connected to the main frame 16-11, and the rubber limit block 16-9 is arranged on the main frame 16-11 and is located in front of the pressure marking station.

[0267] In this embodiment, the fourth servo motor 16 - 1 is connected to the main shaft 16 - 3 via the second coupling 16 - 2 .

[0268] In this embodiment, the third synchronous pulley 16 - 7 and the second synchronous pulley 16 - 6 are connected by an inserting shaft.

[0269] The working process of the label pressing mechanism 16 is as follows:

[0270] This embodiment is driven by a fourth servo motor 16-1, and a second coupling 16-2 is used to connect a main shaft 16-3 attached to the marking wheel. The main shaft 16-3 can drive the first synchronous belt 16-5 above to rotate and swing around its center.

[0271] The main shaft 16-3 rotates, driving the first synchronous pulley 4 to rotate. The first synchronous pulley 4 is connected to the second synchronous pulley 6 in the same plane by the first synchronous belt 16-5, so that the second synchronous pulley 6 follows the rotation, and then transmits it to the upper third synchronous pulley 16-7 through the coaxial transmission. The second synchronous belt 16-8 rotates to roll and compact the self-adhesive on the syringe barrel of the syringe 17, and it must be ensured that the printed handwriting of the label is clear and there is no wrinkle when rolling.

[0272] The role of the rubber stopper 16-9 is to adjust the distance between the upper part of the label pressing mechanism 16 and the main machine 2. One of the functions is to prevent the upper part of the label pressing mechanism 16 from being too close or too far from the main machine 2. If it is too close, the syringe 17 will be squeezed too hard when passing between the upper part of the label pressing mechanism 16 and the main machine 2, and the bottle will be broken. If it is too far, the friction between the syringe 17 and the second synchronous belt will be reduced, so that the label cannot be compacted. The third function is to push the upper part of the label pressing mechanism 16 away, so as to facilitate the maintenance or replacement of a certain component.

[0273] like Fig.25 As shown, the over-rotation detection assembly 8 includes a first detection device 8-1, a second detection device 8-2, a third detection device 8-3, a fourth detection device 8-4, a first fixed bracket 8-5, a second fixed bracket 8-6, a first tightening screw 8-7, a second tightening screw 8-8, a first fixing screw 8-9, a second fixing screw 8-10, a scale 8-11 and a first fixing member 8-12.

[0274] The first detection device 8-1 and the second detection device 8-2 are used to detect the height of the push rod of the syringe 17; the third detection device 8-3 and the fourth detection device 8-4 are used to detect the liquid in the needle cap of the syringe 17; the upper detection mechanism is arranged at the upper section of the first fixing member 8-12; the lower detection mechanism is arranged at the lower section of the first fixing member 8-12; a syringe pull-out wheel assembly 9 for pulling out the syringe 17 is arranged between the upper detection mechanism and the lower detection mechanism.

[0275] The distance between the first detection device 8 - 1 and the second detection device 8 - 2 is greater than the diameter of the plunger of the syringe 17 ; the distance between the third detection device 8 - 3 and the fourth detection device 8 - 4 is greater than the diameter of the barrel of the syringe 17 .

[0276] In this embodiment, the first detection device 8-1, the second detection device 8-2, the third detection device 8-3 and the fourth detection device 8-4 are all photoelectric sensors.

[0277] The first tightening screw 8-7 is used to fix the first detection mechanism on the first fixing bracket 8-5, and the second tightening screw 8-8 is used to fix the second detection mechanism on the second fixing bracket 8-6.

[0278] The first fixing screw 8-9 and the second fixing screw 8-10 are used to fix the scale 8-11 to the first fixing member 8-12.

[0279] In this embodiment, the first fixing member 8 - 12 is a columnar structure.

[0280] This embodiment realizes double detection of the assembled syringe 17 through the upper detection mechanism and the lower detection mechanism. The upper detection mechanism is used to detect the height of the push rod. If the height of the push rod is lower than the set value, it proves that the syringe is over-rotated. If the height of the push rod exceeds the set value, it proves that the syringe is under-rotated. The lower detection mechanism is used to detect the liquid level height of the syringe in the needle cap and whether liquid appears at the bottom of the needle cap. If liquid appears in the needle cap, it proves that there is leakage and the syringe is scrapped. If the liquid height does not match the set value, it proves that the syringe is not properly assembled.

[0281] This embodiment realizes automated syringe assembly detection, solves various drawbacks of manual sorting, has high efficiency, and has good detection effect.

[0282] It should be pointed out that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
