Description

Technical Field

[0001] The present invention relates to the field of watch core injection production equipment, and in particular to an automated injection production line for gas meter cores. Background Art

[0002] A gas meter is an instrument for measuring and settling gas consumption, mainly including a meter case and a core installed in the meter case. The core is processed by an injection molding process. The traditional core processing process includes several steps such as injection molding - detecting the injection molding result - coding - packing and stacking.

[0003] The related technology can refer to the Chinese patent application with the publication number CN116901345A, which discloses a production process for a gas meter drive mechanism. The drive mechanism is integrally formed through an injection molding process step; it includes raw material mixing, drying, injection, spraying and packaging; by integrally injection molding the drive mechanism, the complex processing process of the rotating shaft and the crimping process between the rotating shaft and the driving arm are solved, reducing the production cost and production cycle of the drive mechanism; at the same time, through the integrally injection molding, the wear problem between the rotating shaft and the driving arm is also solved, improving the accuracy and service life of the drive mechanism, and enhancing the metering accuracy of the gas meter; by adding a reinforcing agent and an anti-wear agent to the raw material, the strength of the integrally injection molded drive mechanism is increased, reducing the wear during the use of the drive mechanism and enhancing the service life of the drive mechanism.

[0004] In view of the above related technology, in the existing core production process, it is necessary to transfer the core between different workstations to sequentially complete processes such as injection molding, detection, sorting and coding, and packing of the core. In the prior art, through the combined use of a conveyor belt and a manipulator, the core can be transported and transferred between different workstations, realizing semi-automation of the production process to a certain extent. However, in modern production processes, there are higher requirements for the degree of automation of the production process, such as accurately monitoring the production batch, production quantity, etc. The combined transportation facilities of a simple conveyor belt and a manipulator cannot meet the higher automated production requirements. Therefore, there is an urgent need for a core production line with a higher degree of automation. Summary of the Invention

[0005] In order to improve the automation level of the core injection production process, the present application provides an automated injection production line for gas meter cores.

[0006] The present application provides an automated injection production line for gas meter cores, adopting the following technical solutions: An automated injection production line for gas meter cores includes an injection molding mechanism for forming cores from raw materials by injection molding, a conveying mechanism for transporting the cores along the production and processing sequence, and further includes: a CCD detection area arranged at the end of the injection molding mechanism for distinguishing different cores according to the mold number; The inkjet coding mechanism is arranged at the rear end of the CCD detection area, and sprays information codes on different movement cores according to the classification situation and summarizes and stores the inkjet coding information; The code inspection mechanism is arranged at the rear end of the inkjet coding mechanism, including a code scanning area and a sorting mechanism. The code scanning area scans and identifies the inkjet coding information of the movement core, and then the sorting mechanism eliminates the unqualified inkjet products; The boxing mechanism includes a boxing station and a boxing manipulator. There is a box placed at the boxing station. The boxing manipulator is used to place the movement core into the corresponding box. The box is provided with an RFID card, and a reader-writer is arranged at the boxing station. The reader-writer is used to write information such as the batch number and serial number of the movement core into the RFID card; The box conveying mechanism includes: an empty box output roller line arranged at the starting end of the boxing station, which is used to drive the box to move towards the boxing station; an empty box elevator arranged at the starting end of the empty box output roller line, which is used to lift the box from the storage area and convey the box to the empty box output roller line; an empty box input roller line, which is used to convey the box to the empty box elevator. The RFID card in the box stores the box position information. A reader for reading and identifying the RFID card is arranged at the front end of the empty box input roller line. When the box is placed abnormally, the reader issues an alarm. An empty box sensor is arranged at the end of the empty box input roller line. When the box is missing at the end of the empty box input roller line, the empty box sensor is triggered and issues a prompt.

[0007] By adopting the above technical solutions, the injection molding mechanism processes raw materials into movement cores, and the movement cores are conveyed to the inkjet coding mechanism by the conveying mechanism. Before inkjet coding, the movement core models are identified and the movement cores are differentiated through the CCD detection area. The inkjet coding mechanism performs inkjet coding on the differentiated movement cores and uploads the inkjet coding data to the counter. After inkjet coding is completed, the movement cores are driven to move towards the code inspection mechanism, and the inkjet codes on the movement cores are scanned and identified in the code scanning area. The unqualified inkjet coded products are removed through the sorting mechanism. After sorting is completed, the conveying mechanism moves the movement cores to the packing station, and then the packing robot places the movement cores into the corresponding boxes according to batches and models. The information such as the model and batch of the movement cores is written into the RFID card of the box through the reader. When the box is full of movement cores, the box conveying mechanism removes the full box from the packing station and sends the box and the movement cores into the storage area for storage. During packing, the empty box of the storage area is placed on the empty box input roller conveyor line. The position information of the box is detected through the reader, and the absence of the empty box is monitored through the empty box inductor. The empty box elevator conveys the box in the height direction to enable the box to flow between the storage area and the movement core production area. At the same time, the empty box output roller conveyor line conveys the empty box towards the packing station and can temporarily store the redundant empty boxes to facilitate the replenishment of empty boxes to the packing station. During the injection molding production process of the movement core, processes such as automatic material taking of the injection molding mechanism, automatic identification of the movement core mold number, automatic code inspection, automatic code return, automatic batch packing, automatic recording of packing information, and box movement and transportation are realized, which is beneficial to improving the automation level of the movement core injection molding production process.

[0008] Optionally, the conveying mechanism includes: an injection molding discharge conveyor belt arranged at the discharge end of the injection molding mechanism for taking the movement cores away from the injection molding mechanism; a summary conveyor belt arranged at the tail end of the injection molding discharge conveyor belt for summarizing the movement cores on the injection molding discharge conveyor belt and conveying the movement cores to the inkjet coding mechanism; a transition conveyor belt arranged between the inkjet coding mechanism and the code inspection mechanism for conveying the inkjet coded movement cores to the code inspection mechanism; and a number of handling robots arranged between the conveying mechanism and each processing station for handling the movement cores.

[0009] By adopting the above technical solutions, the number of injection molding discharge conveyor belts and the number of injection molding mechanisms can both be set to multiple to improve production efficiency. The summary conveyor belt summarizes the injection molded movement cores, facilitating the transportation of the movement cores to the inkjet coding mechanism by the handling robots. The transition conveyor belt is used to convey the inkjet coded movement cores to the code inspection mechanism. The movement core conveying process does not require manual handling, improving the automation level.

[0010] Optionally, the handling robot includes: an injection molding material taking robot, which is arranged between the injection molding mechanism and the injection molding discharge conveyor belt and is used to transport the completed injection molded movement from the injection molding mechanism to the injection molding discharge conveyor belt; a transfer material taking mechanism, which is arranged between the injection molding discharge conveyor belt and the summary conveyor belt and is used to transport the movement on the injection molding discharge conveyor belt to the summary conveyor belt; a coding and discharging mechanism, which is arranged between the summary conveyor belt and the CCD detection area and is used to transport the movement to the CCD detection area for detection and transport the sorted movement to the coding mechanism for coding.

[0011] By adopting the above technical solution, the injection molding material taking robot is used to transport the movement from the injection molding mechanism to the injection molding discharge conveyor belt, the transfer material taking mechanism is used to transport the movement from the injection molding discharge conveyor belt to the summary conveyor belt for summarization. Through the coding and discharging mechanism, it is convenient to transport the movement from the summary conveyor belt to the CCD detection area to detect and sort the movement, and transport the sorted movement to the coding mechanism for coding. Then place the movement after coding on the transition assembly line. By setting the handling robot, it is beneficial to further realize the automation in the injection molding production process of the movement.

[0012] Optionally, a number of groups of positioning members are further arranged along the length direction of the conveying mechanism. The positioning members include a number of limiting blocks and a number of positioning rods. A number of limiting blocks are all located on the side edges of the conveying mechanism along the width direction. The positioning rods are located between a number of limiting blocks and are arranged along the position of the hole and groove structure on the movement. Both the positioning rods and the limiting blocks move along the transportation direction of the conveying mechanism.

[0013] By adopting the above technical solution, the limiting blocks limit the movement along the width direction of the conveying mechanism to reduce the probability of the movement shifting during transportation. Further positioning the movement through the positioning rods is beneficial to improve the positioning accuracy of the movement during transportation on the conveying mechanism.

[0014] Optionally, a number of partition plates are fixedly arranged inside the box body. The number of partition plates divide the internal cavity of the box body, so that the box body cavity is divided into a number of storage cavities adapted to the shape of the movement. When the movement is located in the storage cavity, the partition plates and the box body cooperate to limit the movement.

[0015] By adopting the above technical solution, the box body separates the horizontally arranged movements through the partition plates. When the movement enters the corresponding storage cavity, it is in a positioned state, which is beneficial to improve the stacking stability of the movement after being packed in the box.

[0016] Optionally, a pre-packing conveyor belt is arranged at the end of the code inspection mechanism. The sorted qualified products after coding are placed on the pre-packing conveyor belt by batches. A centering box is arranged on one side of the pre-packing conveyor belt. A number of centering blocks are fixedly arranged along the length direction inside the centering box. The centering blocks are adapted to the shape of the movement and are used to center and buffer the movement.

[0017] By adopting the above technical solution, the conveyor belt will transport the qualified movement to the corresponding packing station before packing, and then the packing robot will put the movement into the corresponding box according to the batch and model number. Before packing, the packing robot will put the movement into the alignment box, and further position the movement through the alignment block. After positioning, the movement will be placed in the box, which is beneficial to improve the flatness of the movement when stacked in the box.

[0018] Optionally, the box conveying mechanism also includes: a full box output roller line, arranged at the tail end of the packing station, used to take the boxes filled with the movement away from the packing station; a full box elevator, arranged at the tail end of the full box output roller line, used to drive the boxes on the full box output roller line to lift; a full box input roller line, arranged at the tail end of the full box elevator, used to transport the boxes in the full box elevator to the storage area.

[0019] By adopting the above technical solution, after the box is packed, the box is transported to the full box elevator through the full box output roller line, and the full box elevator moves the box to the storage area. The full box input roller line is used to move the box out of the full box elevator. After the movement is packed, the process of transporting the box to the storage area does not require manual handling, which is conducive to improving the level of automation.

[0020] Optionally, a transplanter is provided between the packing station and the empty box output roller line. The transplanter is used to push the box on the empty box output roller line to the packing station and limit the box. When the box is full of movement, the transplanter removes the box from the empty box station and transports the next box to the packing station.

[0021] By adopting the above technical solution, the transplanter is used to carry empty boxes and full boxes, so that the boxes remain stable during the movement packing process, thereby improving the packing stability of the movement.

[0022] Optionally, the box conveying mechanism also includes a transfer robot, an out-of-warehouse transport vehicle and a cargo support frame. The cargo support frame is arranged in the storage area to support and position the box. The transfer robot is arranged at the head end of the empty box input roller line or the tail end of the full box input roller line to transport the box to the empty box input roller line or to transport the box from the full box input roller line to the cargo support frame. A lifting piece for lifting the box is fixedly provided on the upper end of the out-of-warehouse transport vehicle, and the cargo support frame is provided with an avoidance groove adapted to the lifting piece.

[0023] By adopting the above technical solutions, the transfer manipulator is used to convey the empty box body to the empty box input roller line, or to carry the full box body from the full box input roller line to the goods support frame for stacking. When the movement is out of the warehouse, the out-of-warehouse transport vehicle approaches the goods support frame, and the lifting member extends into the avoidance groove. After the lifting member jacks up the full box body, the box body can be driven out of the storage area. When taking out the movement from the storage area, manual handling is also not required, so as to realize the automation of the whole process of movement injection molding.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. During the injection molding production process of the movement, the processes of automatic material taking of the injection molding mechanism, automatic identification of the movement mold number, automatic inkjet coding, automatic code inspection, automatic code return according to the code, automatic batch packing, automatic recording of packing information, and box body movement and transportation are realized, achieving less manpower and unmanned operation in the production process and improving the automation level of the movement injection molding production process; 2. The inkjet coding data and packing data are uniformly recorded and stored in the database, which is convenient for monitoring the production data of the movement, such as the qualification rates of movement injection molding and inkjet coding, etc. At the same time, by setting an RFID card in the box body, when the movement is out of the warehouse, the out-of-warehouse batch of the movement can be allocated according to the preset process, such as first in first out, first in last out, etc., improving the flexibility when the movement is warehoused and out of the warehouse.

Specific embodiments

[0029] The following further describes the present application in detail in conjunction with all the drawings.

[0030] An embodiment of the present application discloses an automated injection molding production line for a gas meter movement.

[0031] Embodiment: Referring to Figure 1 , an automated injection molding production line for a gas meter movement sequentially includes an injection molding mechanism 1, a coding spraying mechanism 4, a coding inspection mechanism 5, a boxing mechanism, and a box body conveying mechanism 7 according to the movement production process. A conveying mechanism for transporting the movement and a handling robot for handling the movement are also provided between different mechanisms.

[0032] Referring to Figure 2 and Figure 3 , the number of injection molding mechanisms 1 is set according to actual needs. In this embodiment, 6 sets of injection molding mechanisms 1 are taken as an example for illustration. In other embodiments, the injection molding mechanisms 1 can also be set to 3 sets, 4 sets, 5 sets or other quantities. The conveying mechanism includes but is not limited to multiple injection molding discharge conveyor belts 21, and the injection molding discharge conveyor belts 21 correspond to the injection molding mechanisms 1 one by one. The handling robot includes but is not limited to an injection molding material taking robot 31. When the injection molding mechanism 1 produces a movement, the injection molding material taking robot 31 automatically transports the movement to the corresponding injection molding discharge conveyor belt 21. In this embodiment, 3 sets of injection molding material taking robots 31 are provided, and two injection molding discharge conveyor belts correspond to one set of injection molding material taking robots 31, which is beneficial to improving the working efficiency of the injection molding material taking robots 31.

[0033] Referring to Figure 2 and Figure 3 , the conveying mechanism further includes a summary conveyor belt 22, and the summary conveyor belt 22 is arranged at the end of the injection molding discharge conveyor belt 21. All the injection molding discharge conveyor belts 21 drive the movement to move towards the summary conveyor belt 22. The handling robot further includes a transfer material taking mechanism 32, and 3 sets of transfer material taking mechanisms 32 are also provided. Each set of transfer material taking mechanisms 32 corresponds to two injection molding discharge conveyor belts. When the transfer material taking mechanism 32 works, it transports the movement on the corresponding injection molding discharge conveyor belt to the summary conveyor belt 22 for summarization.

[0034] Referring to Figure 2 and Figure 3, the inkjet coding mechanism 4 is arranged at the tail end of the summary conveyor belt 22, and a CCD detection area 41 is arranged at the front end of the inkjet coding mechanism 4. The CCD detection method is a prior art. When it works, it scans and identifies the object's image through cameras at multiple angles. The handling manipulator further includes an inkjet discharging mechanism 33. The inkjet discharging mechanism 33 is arranged between the summary conveyor belt 22 and the inkjet coding mechanism 4. When the movement core approaches the inkjet coding mechanism 4 along with the summary conveyor belt 22, the inkjet discharging mechanism 33 removes the movement core from the summary conveyor belt 22 and places the movement core in the CCD detection area 41, and then differentiates different movement cores according to the mold numbers of the movement cores. Further, a movement core defect detection station can also be arranged in the CCD detection area 41, and defects generated during the injection molding process of the movement core are detected by cooperating with cameras at multiple angles to eliminate defective products generated during the injection molding process.

[0035] Refer to Figure 2 and Figure 3 , the inkjet coding mechanism 4 is connected to a database, and the mold numbers of all movement cores are stored in the database. After the movement cores are differentiated in the CCD detection area 41, the inkjet discharging mechanism 33 transports the movement cores to the inkjet coding position of the inkjet coding mechanism 4 of the inkjet coding mechanism 4 for inkjet coding. When the inkjet coding mechanism 4 works, it uploads the inkjet coding data information to the database. The conveying mechanism includes but is not limited to a transition conveyor belt 23. The transition conveyor belt 23 is arranged at the output end of the inkjet coding mechanism 4. After the inkjet coding mechanism 4 sprays the data information onto the movement cores, the inkjet discharging mechanism 33 transports the movement cores from the inkjet coding mechanism 4 to the transition conveyor belt 23. A centering mechanism is also arranged before the inkjet coding mechanism 4. The centering mechanism is used to adjust the position of the movement cores on the summary conveyor belt 22 so that the positions of all movement cores are the same during inkjet coding, reducing the probability of skewing during the inkjet coding of the movement cores and improving the inkjet coding quality of the movement cores.

[0036] Refer to Figure 2 and Figure 3 , the code inspection mechanism 5 is arranged at the tail end of the transition conveyor belt 23, and the transition conveyor belt 23 drives the movement cores that have completed inkjet coding to move towards the code inspection mechanism 5. The code inspection mechanism 5 includes but is not limited to a scanning area and a sorting mechanism 51, and a pre-packing conveyor belt 52 is also arranged at the tail end of the code inspection mechanism 5. When the transition conveyor belt 23 drives the movement cores to move to the scanning area of the code inspection mechanism 5, the scanning area scans and identifies the information codes sprayed on the movement cores, differentiates the movement cores according to the scanning content, and uniformly places the movement cores of the same batch on the pre-packing conveyor belt 52 through the sorting mechanism 51. During this process, if the code inspection mechanism 5 cannot identify the information code on the movement core, it means that there are defective products during the scanning process of the movement core. There is a defective product box at the code inspection mechanism 5. When the movement core is detected as a defective product, the defective movement core is placed in the defective product box through the sorting mechanism 51.

[0037] Refer to Figure 2 and Figure 3, the injection molding discharge conveyor belt 21, the aggregation conveyor belt 22, the transition conveyor belt 23, and the conveyor belt 52 before packing are all arranged along the length direction and are evenly provided with multiple positioning members 24. The positioning members 24 include, but are not limited to, multiple limit blocks 241 and multiple positioning rods 242. Both the limit blocks 241 and the positioning rods 242 move along the conveying direction of the corresponding conveying mechanism. Among them, multiple limit blocks 241 are evenly arranged on the side edges in the width direction of the corresponding conveying mechanism. The gap between two adjacent limit blocks 241 forms a limit area adapted to the movement mechanism. When conveying the movement mechanism, the movement mechanism is located within the limit area. Multiple limit blocks 241 cooperate to limit from the outside of the movement mechanism, reducing the probability of the movement mechanism shifting during conveying and improving the positioning accuracy when the handling manipulator handles the movement mechanism.

[0038] Refer to Figure 2 and Figure 3 , all the positioning rods 242 are located between two adjacent limit blocks 241. The movement mechanism is provided with a hole and groove structure for connecting the watch case and other components. The distribution of multiple positioning rods 242 on the conveying mechanism is set according to the hole and groove structure of the movement mechanism. When placing the movement mechanism into the corresponding limit area, all the positioning rods 242 are inserted into the corresponding hole and groove structures on the movement mechanism, thereby further positioning the movement mechanism, which is beneficial to improving the positioning effect of the movement mechanism.

[0039] Refer to Figure 2 and Figure 3 , the packing mechanism is arranged at the end of the conveyor belt 52 before packing, and the conveyor belt 52 before packing drives the movement mechanism to move towards the packing mechanism. The packing mechanism includes, but is not limited to, multiple packing stations 61 and packing manipulators 62 corresponding to the packing stations 61. In this embodiment, there are 6 groups of packing stations 61, and one group of packing stations 61 corresponds to the movement mechanism of one type of mold. The packing manipulator 62 is a three-axis manipulator, which can move along the three axes of longitudinal, transverse, and vertical directions.

[0040] Refer to Figure 2 and Figure 3 , boxes 8 are arranged at all the packing stations 61. The box conveying mechanism 7 is arranged at the packing stations 61. The box conveying mechanism 7 includes, but is not limited to, an empty box output roller line 71, an empty box elevator 72, and an empty box output roller line 71. The empty box input roller line 73 is arranged in the movement mechanism storage area. The area where production mechanisms such as the injection molding mechanism 1, the inkjet coding mechanism 4, and the code inspection mechanism 5 are located is set as the movement mechanism production area. Considering the limitation problem of production space in actual production activities, in this embodiment, the movement mechanism storage area and the movement mechanism production area are in different height areas to provide sufficient space for the storage of the movement mechanism and facilitate the storage and outbound of the movement mechanism.

[0041] Refer to Figure 2 and Figure 3, The empty box elevator 72 is arranged at the end of the empty box input roller line 73. When the box body 8 is placed on the empty box input roller line 73, the empty box conveyor roller line drives the box body 8 to move towards the empty box elevator 72. After the empty box body 8 enters the empty box elevator 72, the empty box elevator 72 drives the empty box body 8 to be lifted to the core production area. The empty box output roller line 71 is located between the end of the empty box elevator 72 and the packing station 61. When the empty box body 8 is lifted to the starting end of the empty box output roller line 71, the empty box elevator 72 ejects the empty box body 8 onto the empty box output roller line 71 and conveys it to the packing station 61 through the empty box output roller line 71.

[0042] Refer to Figure 2 and Figure 3 , At the packing station 61, a transfer machine 74 is provided. The transfer machine 74 is arranged at the end of the empty box output roller line 71. When the empty box body 8 approaches the transfer machine 74, the transfer machine 74 transports a single box body 8 to the packing station 61. When there are multiple box bodies 8 on the empty box output roller line 71 at the same time, the transfer machine 74 limits the excess box bodies 8, so that the remaining empty box bodies 8 are temporarily stored on the empty box output roller line 71. When the box body 8 moves to the packing empty position, the packing manipulator 62 puts the core on the corresponding pre-packing conveyor belt 52 into the box body 8.

[0043] Refer to Figure 2 and Figure 3 , Further, an RFID card is installed in the box body 8. The RFID card is used to store the position and orientation information of the box body 8. An RFID reader is also provided at the starting end of the empty box input roller line 73. When the empty box body 8 is placed on the empty box input roller line 73, the RFID reader reads the information in the RFID card on the box body 8. When the orientation of the box body 8 is incorrect or the RFID card is damaged, the RFID reader issues an alarm to remind the operator to adjust the box body 8 or remove the box body 8. An empty box sensor is also installed at the end of the empty box input roller line 73. When there is no empty box body 8 on the empty box input roller line 73, the empty box sensor is triggered to remind the operator to replenish the empty box body 8.

[0044] Refer to Figure 2 and Figure 3 , An RFID reader / writer is also installed at the packing station 61. The RFID reader / writer is connected to the database. When the transfer machine 74 drives the empty box body 8 to be positioned at the packing station 61, the RFID reader / writer inputs information such as the batch number and serial number of the core into the RFID card of the box body 8 according to the core model corresponding to the packing station 61. A plurality of partition plates 81 are fixedly arranged in the box body 8. The plurality of partition plates 81 are arranged in a staggered manner in the horizontal and vertical directions, and the cavity in the box body 8 is divided into a plurality of storage cavities corresponding to the core size. When the core is packed, after the core is put into the storage cavity by the packing manipulator 62, the core contacts the side wall of the box body 8 or the partition plate 81 and is in a positioned state.

[0045] Referring to Figure 2 and Figure 3 Before boxing, an alignment box 53 is installed on one side of the conveyor belt 52 before boxing. The alignment box 53 is parallel to the conveyor belt 52 before boxing. A plurality of alignment blocks 531 are installed along the length direction inside the alignment box 53. The structure of the upper end surface of the alignment block 531 is adapted to the movement mechanism. The plurality of alignment blocks 531 respectively correspond to movement mechanisms of different models. Before the boxing manipulator 62 boxes the movement mechanism, it places the movement mechanism into the alignment box 53 and sleeves the movement mechanism from top to bottom on the corresponding alignment block 531. The position of the alignment block 531 is fixed, thereby further positioning the movement mechanism. The movement trajectory of the boxing manipulator 62 and the position of the box body 8 are both fixed. Therefore, the position of the storage cavity is also fixed. After the movement mechanism is corrected by the alignment block 531, it is directly opposite to the storage cavity. When the boxing manipulator 62 transports the movement mechanism to the storage cavity of the box body 8, the stacking is neat, which is beneficial to improving the stacking stability of the movement mechanism.

[0046] Referring to Figure 2 and Figure 3 The box body conveying mechanism 7 further includes a full-box output roller line 75, a full-box elevator 76, and a full-box input roller line 77. The starting end of the full-box output roller line 75 is located at the boxing station 61. When the box body 8 is filled with movement mechanisms, the transplanting machine 74 transports the full-box body 8 to the full-box output roller line 75 and transports the empty box on the empty box input roller line 73 to the boxing station 61 for boxing the next batch of movement mechanisms. Multiple buffer positions are set at the boxing station 61. The buffer positions are used to buffer the movement mechanisms. When replacing the empty box body 8, the movement mechanisms are temporarily stored through the buffer positions, thereby reducing the probability of the movement mechanisms piling up due to insufficient blanking time of the empty box body 8.

[0047] Referring to Figure 2 and Figure 3 The full-box elevator 76 is arranged at the tail end of the full-box output roller line 75 and is arranged between the movement mechanism storage area and the movement mechanism production area. When the full-box body 8 enters the full-box elevator 76 driven by the full-box output roller line 75, the full-box elevator 76 drives the full-box body 8 to be conveyed to the movement mechanism storage area. The full-box input roller line 77 is arranged at the tail end of the full-box elevator 76. When the full-box elevator 76 drives the full-box body 8 to move to the movement mechanism storage area, it ejects the box body 8 onto the full-box input roller line 77, so that the full-box input roller line 77 takes the box body 8 away from the full-box elevator 76.

[0048] Referring to Figure 2 and Figure 3, the box conveying mechanism 7 further includes a transfer manipulator 78, an out-of-warehouse transport vehicle 79, and a goods support frame 710. The goods support frame 710 is installed in the storage area, and a support plate adapted to the box 8 is fixedly provided at the upper end of the goods support frame 710. The transfer manipulator 78 is installed between the goods support frame 710 and the full-box input roller line 77. When the full-box 8 approaches the goods support frame 710, the transfer manipulator 78 transports the box 8 from the full-box input roller line 77 to the goods support frame 710. Multiple boxes 8 containing the same batch of movement cores are stacked on the same goods support frame 710.

[0049] Referring to Figure 2 and Figure 3 , the out-of-warehouse transport vehicle 79 is an AGV vehicle and can automatically travel along a preset route. A lifting member 791 is installed at the upper end of the out-of-warehouse transport vehicle 79, and the lifting member 791 moves synchronously with the out-of-warehouse transport vehicle 79. An avoidance groove 711 adapted to the lifting member 791 is provided at the upper end of the goods support frame 710. When it is necessary to take the movement core out of the warehouse, the out-of-warehouse transport vehicle 79 is manipulated to enter below the goods support frame 710. At this time, the lifting member 791 passes through the avoidance groove 711 to lift the box 8 above the goods support frame 710. After the out-of-warehouse transport vehicle 79 lifts the box 8, it moves out of the movement core storage area again according to the established route, thereby completing the automatic out-of-warehouse of the movement core.

[0050] The working principle of an automated injection production line for a gas meter movement in an embodiment of the present application is as follows: When injecting and producing the movement, through the cooperation of the conveying mechanism and the handling manipulator, automatic material taking after injection of the movement is realized. In the inkjet coding process, the movement is identified and distinguished by the CCD detection area 41. Information such as inkjet coding and scanning of the movement is summarized through the database, thereby facilitating the monitoring of the qualification rate of the movement during the process from injection to inkjet coding. At the same time, the sorted mechanism 51 distinguishes the inkjet-coded movements so as to place the movements with the same batch and serial number on the corresponding conveyor belt 52 before boxing, realizing the automatic sorting of the movements. The boxing process is automated through the boxing manipulator 62, and information such as the batch and serial number of the movement placed in the box 8 is written into the RFID card through the RFID reader. When the movement is out of the warehouse, the RFID card of the box 8 facilitates the quick identification and search for the required batch or model of the movement, and by setting the box conveying mechanism 7, the empty box 8 is automatically conveyed to the boxing station 61, and the full-box 8 is automatically conveyed to the movement core storage area for storage. When the movement is out of the warehouse, the out-of-warehouse transport vehicle 79 transports the box 8 and the movement by itself. The whole process of injection material taking, inkjet coding, scanning, sorting, boxing, in-storage storage, and out-of-warehouse of the movement realizes automation, improving the automation level of the movement injection production process.
