[0021] It should be further understood that the term "and / or" used in this specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the related listed items, and includes these combinations.

[0022] Next, please refer to Figure 1 and Figure 2 , the embodiments of the present invention provide an offline blanking device applicable to the packaging and testing system of Product 1. The packaging and testing system of Product 1 includes a molding machine and a testing and sorting machine. The device includes: A turntable assembly 2 for conveying Product 1. The turntable assembly 2 is arranged around the molding machine. The turntable assembly 2 includes a discharging station 22 in the middle and a blanking station 23 at the end. A discharging and testing assembly 4, one end of which is connected to the discharging station 22 and the other end is connected to the testing and sorting machine, for discharging Product 1 to the testing and sorting machine. An offline blanking assembly 5, connected to the blanking station 23, for controlling the offline blanking of Product 1.

[0023] In this embodiment, the offline blanking device includes a turntable assembly 2, a discharging and testing assembly 4, and an offline blanking assembly 5. Among them, the turntable assembly 2 is arranged around the molding machine, including a discharging station 22 in the middle and a blanking station 23 at the end, and is used to undertake the function of product 1's station transfer. The two ends of the discharging and testing assembly 4 are respectively connected to the discharging station 22 of the turntable and the testing and sorting machine, and are used to realize the precise conveying and detection connection of product 1 to the testing and sorting machine. The offline blanking assembly 5 is directly docked with the blanking station 23 at the end of the turntable, and is used to realize the controllable offline blanking of product 1.

[0024] In this embodiment, by setting the discharging and testing assembly 4 and the offline blanking assembly 5, product 1 can be conveyed out from different stations. In this way, the effect of intermittent offline blanking can be realized during the automated on-line production process. Furthermore, during the full production of the testing and sorting machine, the surplus production capacity of the molding machine can be processed by offline blanking. For example, the offline blanked product 1 can be conveyed to an independent testing machine for production, so as to maximize the utilization rate of the molding machine in the automated on-line production mode, thereby improving the production testing efficiency and production capacity balance of product 1. In actual verification, through the offline blanking device provided in this embodiment, the utilization rate of the molding machine can be increased by 20% in the automated production mode of connecting the IPM molding machine and the testing and sorting machine.

[0025] In one embodiment, the offline blanking assembly 5 includes an offline blanking track 51 that is inclined from high to low along the conveying direction of product 1. A material pipe 53 for loading product 1 is detachably arranged above one end of the offline blanking track 51 away from the blanking station 23.

[0026] In this embodiment, by setting the offline blanking track 51 and the material pipe 53, the effective collection and temporary storage of the offline blanked product 1 can be realized. When product 1 is conveyed to the offline blanking assembly 5 through the blanking station 23 of the turntable assembly 2, they will slide down along the offline blanking track 51 into the material pipe 53. In practical applications, the track length of the offline blanking track 51 needs to be set considering the convenience of operation, the slope of the track should consider the interval that product 1 passes through to prevent material jamming, and the design of the material pipe 53 allows users to easily disassemble and replace it, so as to collect the full pipe of product 1 or transfer product 1 to other processing areas. In addition, the setting of the material pipe 53 also helps to reduce the damage of product 1 during the offline blanking process and ensure the integrity of product 1.

[0027] In one embodiment, a tube guide block 52 is provided between the offline blanking track 51 and the material tube 53. The height of the tube guide block 52 is lower than that of the offline blanking track 51 and higher than that of the material tube 53. By providing the tube guide block 52, the product 1 can be further guided to accurately fall into the material tube 53, avoiding deviation or dropping of the product 1 during the sliding process. The design of the tube guide block 52 not only improves the accuracy of offline blanking but also enhances the stability and reliability of the entire offline blanking assembly 5.

[0028] In practical applications, the tube guide block 52 can be designed according to the structure of the material tube 53, and it is necessary to follow the principle that the position height of the guide block product 1 should be lower than the product 1 surface height of the offline blanking track 51 on the one hand and higher than the product 1 surface height of the material tube 53 on the other hand, so that the product 1 can smoothly enter the material tube 53. Here, specifically, four pin-type inserts can be designed to insert into the material tube 53 to solve the problem of inconsistent deformation of the plastic material tube 53 and ensure the smoothness of feeding.

[0029] In one embodiment, a first detection unit 55 is provided at the tail of the material tube 53 for detecting the presence of the material tube 53.

[0030] In addition, a second detection unit 56 is also provided at the tail of the material tube 53 for detecting whether the product 1 in the material tube 53 is full.

[0031] In this embodiment, by providing the first detection unit 55 and the second detection unit 56, the presence or absence of the material tube 53 and whether the product 1 in the material tube 53 is full are respectively detected. For example, when the first detection unit 55 detects the presence of the material tube 53, it can be confirmed that the offline blanking assembly 5 has correctly installed the material tube 53, thereby allowing the product 1 to enter the offline blanking process. When the second detection unit 56 detects that the product 1 in the material tube 53 is full, an alarm can be issued in a timely manner or the offline blanking operation can be paused to avoid overloading of the material tube 53 or overflow of the product 1. The setting of these two detection units greatly improves the automation degree and intelligent level of the offline blanking process, ensuring the accuracy and efficiency of the offline blanking of the product 1. In a specific embodiment, both the first detection unit 55 and the second detection unit 56 are photoelectric detectors, that is, the presence or state of the target object is detected by emitting and receiving light beams. For example, when the material tube 53 is installed in place, it will block the light beam of the first detection unit 55, thereby triggering a detection signal to confirm the presence of the material tube 53. Similarly, when the product 1 in the material tube 53 accumulates to a certain extent and blocks the light beam of the second detection unit 56, a detection signal will also be triggered, indicating that the material tube 53 is full. This photoelectric detection method has the advantages of fast response speed and high detection accuracy, and is very suitable for application scenarios such as offline blanking that require high-precision control.

[0032] In some preferred embodiments, for the first detection unit 55, a metal induction type photodetector can be selected, and for the second detection unit 56, a transmissive photodetector can be selected. Whether it is a metal induction type photodetector or a transmissive photodetector, the detection sensitivity can be controlled by adjusting the amplifier to improve the detection reliability.

[0033] In one embodiment, above the upper end of the offline blanking track 51 close to the blanking station 23 and between it and the material pipe guide block 52, a cover plate 54 is provided, and the cover plate 54 is provided with a hollow part 541.

[0034] By providing the cover plate 54, it can effectively prevent the product 1 from being interfered with or polluted by the external environment during the offline blanking process. The design of the cover plate 54 not only protects the cleanliness of the product 1 but also ensures the smooth progress of the offline blanking process. In practical applications, the cover plate 54 can be designed with an outer shape corresponding to the track. At the same time, the hollow part 541 on the cover plate 54 is beneficial for observing the product 1 in the track and manually cleaning the product 1 or dealing with jammed materials. The size and quantity of the hollow part 541 can be set according to actual needs. This ingenious structural design not only ensures the smooth conveyance of the product 1 but also enhances the practicality and flexibility of the entire offline blanking assembly 5.

[0035] In one embodiment, the turntable assembly 2 further includes a feeding station 21 at the head end, and the feeding station 21 is connected to a feeding assembly 3.

[0036] Further, the feeding assembly 3 includes a feeding guide rail, and the discharging and testing assembly 4 includes a discharging guide rail; The feeding guide rail, the discharging guide rail, and the offline blanking guide rail are all arranged as double guide rails. Correspondingly, two material pipes 53 are also correspondingly provided.

[0037] In this embodiment, the double guide rail setting method can ensure that the product 1 is more stable and fast during the conveying process, thus effectively improving the conveying efficiency of the product 1. In addition, the double guide rail setting also helps to reduce the downtime caused by guide rail failures. In a single guide rail design, once the guide rail fails, the entire production line may stop running, resulting in a significant decrease in production capacity. While in the double guide rail design, when one guide rail fails, it can quickly switch to the other guide rail to ensure the continuous operation of the production line, thereby minimizing the downtime and improving the overall production capacity. Therefore, this embodiment not only improves the conveying accuracy and stability of the product 1 but also effectively enhances the production capacity and efficiency.

[0038] In some alternative embodiments, in addition to including a feeding station 21, a discharging station 22, and a blanking station 23, the turntable assembly 2 may further be provided with at least one detection station. For example, a vision detection unit 24 may be provided at any one or more of the other stations, so as to perform real-time monitoring and quality control on the product 1 through the vision detection unit 24. The vision detection unit 24 can capture the image information of the product 1 and use image recognition technology to detect the product 1 in terms of dimensions, shape, color, etc., to ensure that the quality of the product 1 meets the preset standards. When a defect or non-conformance is detected in the product 1, the vision detection unit 24 will issue an alarm in a timely manner and notify the control system to perform corresponding processing, such as guiding the defective product 1 to a specific recycling station or marking it as a non-conforming product 1. This setting not only improves the quality and production efficiency of the product 1, but also helps to reduce the generation of defective products and lower the production cost.

[0039] In an actual application scenario, the turntable assembly 2 is provided with a total of 10 stations, where the feeding station 21 and the blanking station 23 are respectively located at the two ends, and the discharging station 22 is located at the 7th station. At the same time, the vision detection unit 24 is located at the 4th station. After the pins of the IPM product 1 are formed, it enters the feeding guide rail of the feeding assembly 3 and enters the feeding station 21 of the turntable assembly 2 through the feeding guide rail, and the turntable is driven to rotate clockwise by servo. At this time, if in the normal production mode, the product 1 will pass through stations such as the vision detection station and reach the 7th station, that is, the discharging station 22, and then enter the discharging test assembly 4 through the discharging station 22, and then enter the test sorting machine through the discharging guide rail of the discharging test assembly 4. If in the offline blanking mode, the product 1 will pass through intermediate stations including the vision detection and the discharging station 22 and reach the last station, that is, the blanking station 23, and then enter the blanking test assembly through the blanking station 23, and then enter the material pipe 53 through the offline blanking guide rail of the blanking test assembly.

[0040] In a specific embodiment, the offline blanking device may further include control modules such as a controller and a PLC host computer. For example, a touch screen is used as the controller, so that the user can directly perform touch operations on the touch screen and issue a blanking control instruction for the product 1 to the offline blanking device through the PLC host computer, so that the offline blanking device controls the flow direction of the product 1 according to the blanking control instruction to the discharging test assembly 4 or the offline blanking assembly 5.

[0041] In an actual application scenario, when the user performs touch operations on the touch screen, the operation interface of the touch screen is described as follows: User selection: The operator or engineer can be selected, and the engineer has advanced setting permissions; Production quantity: It refers to the real-time production quantity of the molding machine, and a manual clearing button is provided below; Interval value: It refers to the current real-time interval value. When the set interval number is reached, this value automatically resets to zero and starts counting again. There is also a manual clear button; Quantity of parts unloaded: It refers to the quantity of Product 1 that the offline part unloading device has currently received. There is a manual clear button; Status light: When the green light is on, it indicates that the function of the offline part unloading device is enabled. The red light indicates it is off; Part unloading light: The light turns green once for each reception of Product 1 during part unloading; Lack of material pipe 53 light: When any track lacks the material pipe 53, this light flashes for alarm; Full material light: When any one of the material pipes 53 is full of material, this light flashes for alarm; Advanced settings: Using the engineer's permission, click this button to enter the next page of the setting screen; Offline part unloading function switch: The switch for this offline part unloading function; Full material stop function switch: A switch to determine whether to automatically stop the molding machine when the offline part unloading material pipe 53 is full; Interval setting: The minimum setting is 4 and the maximum is 10, indicating that for every several products produced by the molding machine, 1 Product 1 enters the offline part unloading device; Password modification: Modify the engineer's login password.

[0042] Correspondingly, using the ladder diagram programming method, the use and annotation of each component are shown in Table 1: Table 1

[0043] Combined with Table 1, the control program of the PLC host computer is as follows: When the PLC is running, the M21 function switch is on, the device is in operation X3, and there is no lack of material and no alarm: (1) When the counting photoelectric X0 senses 1 Product 1, the production quantity in register D211 increases by 1, and at the same time, the number of intervals D230 also increases by 1; (2) M20 lights up indicating that the offline part unloading is in operation; (3) When the number of intervals D230 is equal to the set interval number D400 and there is no full material, the LED light source Y1 is set to work; (4) When Y1 is set, the quantity of parts unloaded D213 increases by 2; When the offline part unloading function is running, when the LED light source Y001 is set at the rising edge, the running light X3 of the die cutting and forming equipment lights up at the rising edge signal, the green light lights up at the rising edge signal, or the number of intervals resets at the rising edge signal, the number of intervals D230 is reset; When the offline part unloading function is running, when the number of intervals D230 is equal to 1 or both of the two part unloading material pipes 53 are full, X1 and X2 are closed, or when the function switch is closed at the rising edge signal, the LED light source is reset; When the signals X1, X2 or the material shortage signal M26 are lit, the full material signal M27 is triggered to close, and at the same time, the red light Y7 is lit. When there is no full material for X1 and X2 has no signal, and it is in the normal operation state without alarm, the green light Y5 is lit. When the detection optoelectronics X4 or X5 detect the empty material tube 53, the M26 material extraction tube signal is triggered to close. When the offline material discharging function is turned off, the LED light source is reset. When the production quantity on the touch screen is zeroed and triggered by the rising edge signal of M23, the production quantity of D211 is zeroed. When the material discharging quantity on the touch screen is zeroed and triggered by the rising edge signal of M24, the material discharging quantity of D213 is zeroed. When the offline material discharging function is turned off and the offline material discharging process is not in the running state, the yellow light Y6 is lit. When the full material signal X1 or X2 is triggered to close, and the full material stop function switch M31 is turned on, the full material stop Y3 is triggered to close, and the device stops. When it is full or short of material, M27 closes, or the full material stop Y3.

[0044] As Figure 3 shown, an embodiment of the present invention also provides an offline material discharging control method, which is applied to the offline material discharging device as described above. The control method includes: steps S101~S102.

[0045] Step S101: Use the turntable assembly 2 to convey the product 1. Step S102: Respectively convey the product 1 to the discharging test assembly 4 and the offline material discharging assembly 5 through the discharging station 22 and the material discharging station 23 in the turntable assembly 2, so as to convey the product 1 to the corresponding test area through the discharging test assembly 4, and convey the product 1 to the corresponding material discharging area through the offline material discharging assembly 5.

[0046] In this embodiment, in the IPM packaging test process, when adopting the automated production mode of connecting the IPM molding machine and the test sorting machine, the product 1 is conveyed through the turntable assembly 2, and then through the discharging station 22 and the material discharging station 23 in the turntable assembly 2, the product 1 is respectively conveyed to the discharging test assembly 4 and the offline material discharging assembly 5, so as to realize the corresponding conveyance of the product 1 in the test area and the material discharging area.

[0047] In this embodiment, by setting up the discharging test component 4 and the offline discharging component 5, the product 1 can be conveyed out from different workstations. In this way, the effect of intermittent offline discharging can be achieved during the automated on-line production process. Furthermore, during the full production of the test sorter, the surplus production capacity of the molding machine can be processed by offline discharging. For example, the product 1 for offline discharging can be conveyed to an independent testing machine for production, so as to maximize the utilization rate of the molding machine in the automated on-line production mode, thereby improving the production test efficiency and production capacity balance of the product 1. In actual verification, through the offline discharging device provided in this embodiment, the utilization rate of the molding machine can be increased by 20% in the automated production mode where the IPM molding machine is connected to the test sorter.

[0048] In one embodiment, as Figure 4 shown, step S102 includes: steps S201 to S203.

[0049] Step S201, in response to the conveying strategy, obtain the discharging interval data in the conveying strategy; Step S202, when the discharging interval data is greater than 0, then convey the product 1 corresponding to the data to the discharging test component 4 and the offline discharging component 5 at intervals according to the discharging interval data; Step S203, when the discharging interval data is equal to 0, then convey all the product 1 to the offline discharging component 5.

[0050] In this embodiment, the discharging interval data is extracted from the conveying strategy, such as non-interval discharging or discharging once every 5 times, etc. Among them, the conveying strategy can be obtained by user input or automatically generated based on historical data. Additionally, here, if the discharging interval data is greater than 0, then the product 1 is conveyed to the discharging test component 4 and the offline discharging component 5 at intervals according to this data. For example, if the discharging interval data is 5, that is, after conveying the product 1 to the discharging test component 4 for 5 times, convey the product 1 to the offline discharging component 5 once. And if the discharging interval data is 0, then all the product 1 is conveyed to the offline discharging component 5. Thus, the user can set different discharging interval data according to specific production requirements to achieve flexible allocation of the product 1. For example, during peak hours, most of the product 1 may need to be directly conveyed to the discharging test component 4 to meet urgent testing requirements; while during non-peak hours, the number of product 1 for offline discharging can be increased to balance the overall production rhythm. By adjusting the discharging interval data, the user can flexibly respond to different production situations according to the actual situation and achieve optimal allocation of production resources. During specific implementation, the user can conveniently input or modify the discharging interval data through an interactive interface such as a touch screen. The system will automatically adjust the conveying strategy of the product 1 according to the data set by the user without manual intervention, greatly improving the automation degree and efficiency of production.

[0051] In actual production applications, first, two empty material tubes 53 are placed. Enter the password on the touch screen to enter the engineer's privilege, set the interval quantity, for example, set it to 5, and turn on the offline cutting function switch with intervals. Reset the count manually, and then start the molding machine and the test and sorting machine. After every 10 products 1 produced by the molding machine enter the track of the test and sorting machine, 2 products 1 will automatically enter the offline cutting track 51. When the full-material detection photoelectric sensor (i.e., the second detection unit 56) in the material tube 53 on the offline cutting track 51 detects the product 1, it indicates that the material tube 53 is full, and the offline cutting with intervals automatically stops. At this time, an audible and visual alarm is triggered, and the molding machine and the test and sorting machine automatically operate normally in the original mode without stopping. Manually remove the two full-material tubes 53. At this time, the audible and visual alarm is still in the alarm state. Then, put in 2 empty material tubes 53, and the offline cutting with intervals automatically starts to run, and the audible and visual alarm automatically cancels the alarm. During normal operation, no other operations are required except for replacing the material tube 53, and the replacement of the material tube 53 is fast and convenient. When this function needs to be turned off, enter the password on the touch screen to enter the engineer's privilege and click to turn off the offline cutting function switch with intervals. If the interval value is set to 0, all the materials cut by the molding machine will enter the offline cutting track 51, realizing the offline operation of the molding machine and solving the problem of waste caused by the idle waiting of the molding machine in case of a failure of the test and sorting machine.
