Description

Technical Field

[0001] The present invention relates to the technical field of tray feeding, and more specifically to a chip placement machine material feeding error prevention method and system. Background Art

[0002] The tray supply structure in patch processing is usually composed of multiple feeders and racks. The feeders correspond to the stations on the patch machine one by one. The racks are equipped with multiple trays to facilitate the replacement of the feeders. The following process is used for material connection and material continuation:

[0003] Scan the station code of the patch machine - scan the feeder code of the patch machine - scan the corresponding tray A of the feeder (at this time, tray A is on the tray bracket of the feeder) - take the tray B for refilling from the rack - tray A is successfully compared with tray B - untie the A tray (empty) and the material belt, at this time the material belt is on the feeder, tray A is separated from the material belt, and the empty tray A is placed aside - untie the lead belt of tray B and connect it with the material belt on the feeder - place tray B on the tray bracket;

[0004] However, according to user feedback, in the actual production operation process, because the empty tray A was not taken away and confirmed to have been taken away in time, in the step of "untying the lead belt of tray B and connecting it with the tape on the feeder", even if the code was scanned and confirmed in the previous operation, when tray B was placed on the feeder, it was often put in the wrong position due to human negligence (tray A was not taken away and confirmed, and no empty space was left), which led to the wrong tray being connected. That is, tray B, which should have been connected to the tape separated from tray A, was connected to other adjacent tapes, resulting in mismatch between the welding position and the welding material, causing considerable losses to users. This has become an industry pain point in the patch industry. Moreover, due to the concealment and suddenness of this type of accident, it is difficult to be discovered, and conventional means are difficult to avoid the occurrence of this type of accident. There is an urgent need for a patch machine material refilling and error prevention method and system that can solve this industry pain point. Summary of the invention

The method is as follows:

[0021] Configure a barcode scanner or a second monitoring unit as the set barcode scanning unit;

[0022] The timing starts when the first monitoring unit detects that the first material tray is taken away from the feeder. If no scanning information feedback is received from the barcode scanner or the second monitoring unit within the set time after the timing starts, it is considered to be timed out and an alarm is issued, otherwise it is considered not to have timed out;

[0023] If manual monitoring is used to determine whether the first tray in the feeding area on the feeder has been taken away, the method for determining whether the data of the tray being scanned by the scanning unit corresponding to the tray storage area is received within the set time is as follows:

[0027] The method for obtaining the tray ID information by identifying the data of the tray code scan is as follows:

[0028] The barcode scanner gun is used to scan the barcode of the scanning container or the piercing rod to identify the ID and verify it. If the verification passes, the barcode scanner gun is used to scan the barcode of the material tray to be placed or has been placed to obtain the material tray ID information. If the verification fails, an alarm is issued.

[0029] The chip placement machine material refilling error prevention method of the present invention comprises a code scanning shelf for storing or temporarily storing material trays, the code scanning shelf is bound to a single or multiple feeders, and multiple rows of material storage slots on the code scanning shelf constitute a material tray storage area; the second monitoring unit is arranged on the material storage slot on the code scanning shelf;

The following is adopted: a code scanning gun or a second monitoring unit is configured as the set code scanning unit; the timing starts from when the first monitoring unit detects that the first material tray is taken away from the feeder. If the code scanning information feedback is not received from the code scanning gun or the second monitoring unit within the set time after the timing starts, it is determined that the timeout has occurred and an alarm is issued, otherwise it is determined that the timeout has not occurred;

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be described clearly and completely in combination with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are partial embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0047] Embodiment 1

[0048] The preferred embodiment of the present invention is a method for preventing errors in the material feeding of a chip placement machine. Figure 1 As shown, the following steps are included:

[0049] S01: manually monitor whether the first material tray in the loading area on the feeder has been taken away. If not, no action is taken, otherwise proceed to the next step;

[0050] S02: Determine whether the data of the scanning unit corresponding to the tray storage area scanning the tray is received within the set time, if yes, proceed to the next step, otherwise, issue an alarm;

[0051] S03: Obtaining tray ID information by identifying the data of the tray code scan, determining whether it is the first tray according to the tray ID information, if yes, determining that the first tray is in a confirmed removal state, otherwise, issuing an alarm;

[0052] By applying the method of the present application, by manually monitoring whether the material tray on the feeder has been removed and performing delayed scanning to confirm, it can be ensured that the material tray has been removed from the feeder, thereby reducing the probability of misplacement due to failure to leave space for material refilling on the feeder, and the feeding processing is safer.

[0053] Preferably, the method further comprises the steps of:

[0054] S04: manually monitor whether the empty position left by taking away the first tray on the feeder is loaded with a second tray, and whether the second tray is a feed tray corresponding to the first tray. If so, proceed to the next step, otherwise, do not act;

[0055] S05: Check whether the first material tray is in the confirmed removal state, if yes, issue a reminder to continue to refill, otherwise, issue an alarm;

[0056] Through the above two steps, it can be ensured that the second material tray has been placed on the empty space left after the first material tray is removed; it should be noted that S04 can be between S01 and S02, between S02 and S03, or after S03, and this solution can be implemented in all of them, and the solutions corresponding to these three positions all belong to the protection scope of this application;

[0057] Preferably, the method for determining whether it is the first tray according to the tray ID information is as follows:

[0058] Scan the first material tray on the feeder to obtain and store the ID information of the first material tray, or call the ID information of the first material tray that has been identified and stored (that is, the information of the first material tray has been registered and stored in the previous feeding stage);

[0059] Identify the tray scan code data to obtain the tray ID information;

[0060] Compare the material tray ID information with the stored ID information of the first material tray, and determine whether it is the first material tray based on the comparison result;

[0061] Of course, it can be understood that the above identification and judgment method is only for illustration and is not intended to be limiting or exclusive. Other existing identification methods may also be used. The solution obtained by simply replacing the existing technology based on this identification method also falls within the scope of protection of this application.

[0062] Correspondingly, when manually monitoring whether the first material tray in the feeding area on the feeder is taken away, it is determined whether the data of the material tray being scanned by the scanning unit corresponding to the material tray storage area is received within the set time. The method is as follows:

[0063] Configure a barcode scanner or a second monitoring unit as the set barcode scanning unit;

[0064] The first tray taken away is manually scanned and the timing starts from the time of scanning. If no scanning information feedback is received from the barcode scanner or the second monitoring unit within the set time after the timing starts, it is considered to be timed out and an alarm is issued, otherwise it is considered not to be timed out;

[0065] That is, after manually taking down the first tray, a code scan is required to determine the initial time of the timing, and then the first tray is placed in the tray storage area, and the code scanning unit scans the code to determine the end time of the timing, and this period of time is set as the delay time;

[0066] Since in this embodiment, manual monitoring is adopted for the first material tray, accordingly, it is necessary to manually remove the first material tray and immediately scan the code for the first time to determine the initial time. This step can set rules and regulations to constrain the workers. If the second scan code is not performed for confirmation within the delay time, it means that the placement action of the first material tray after removal has timed out and an alarm is issued.

[0067] Preferably, a scanning container (such as a box, a basket, a storage barrel or other container) or a through rod (such as a vertical rod arranged on a bottom plate) for storing or temporarily storing the material tray is configured, and the internal storage space of the scanning container or the material storage space of the through rod is the material tray storage area;

[0068] If a barcode scanning gun is configured, it can be set independently of the barcode scanning container or the piercing rod; if a second monitoring unit (such as an infrared counter-radiation sensor, etc.) is configured, it can be set on the barcode scanning container or the piercing rod;

[0069] The method used to obtain the tray ID information by identifying the data of the tray code scan is as follows:

[0070] Use the barcode scanner to scan the container or rod to identify the ID and verify it. If the verification is passed, the barcode scanner will scan the barcode of the tray to be placed or has been placed to obtain the tray ID information. If the verification fails, an alarm will be issued;

[0071] This method is more suitable for the case where the first material tray and the material belt have not been separated. The scanned container or the rod can be easily moved to a position close to the feeding area of ​​the feeder, which is convenient for the subsequent separation operation of the first material tray and the material belt.

[0072] Another preferred method is to configure a code scanning shelf for storing or temporarily storing material trays, the code scanning shelf is bound to a single or multiple feeders, and multiple rows of material storage slots on the code scanning shelf constitute a material tray storage area; a second monitoring unit is provided on the material storage slot on the code scanning shelf;

[0073] The method used to obtain the tray ID information by identifying the data of the tray code scan is as follows:

[0074] When the material tray is placed into the material storage slot of the code scanning shelf, the second monitoring unit is triggered to scan the code of the first material tray;

[0075] This method is more suitable for use when the first material tray and the material belt have been separated. The code scanning shelf can be set to accommodate a larger number of material trays, and automatically scans and senses when they are placed in, which is beneficial to improving confirmation efficiency.

[0076] Embodiment 2

[0077] This embodiment is basically the same as the first embodiment, and the similarities are not repeated here. Figure 2 As shown, the differences are:

[0078] S11: Monitor whether the first material tray in the loading area on the feeder is taken away by the first monitoring unit. If not, no action is taken, otherwise proceed to the next step;

[0079] S12: Determine whether the data of the scanning unit corresponding to the tray storage area scanning the tray is received within the set time, if yes, proceed to the next step, otherwise, issue an alarm;

[0080] S13: Obtaining tray ID information by identifying the data of the tray code scan, determining whether it is the first tray according to the tray ID information, if yes, determining that the first tray is in a confirmed removal state, otherwise, issuing an alarm;

[0081] By applying the method of the present application, the first monitoring unit is used to monitor whether the material tray on the feeder has been removed, and a delayed code scanning confirmation is performed to ensure that the material tray has been removed from the feeder, thereby reducing the probability of misplacement caused by not leaving space for material refilling on the feeder, and the feeding processing is safer.

[0082] Preferably, the method further comprises the steps of:

[0083] S14: Monitor through the first monitoring unit whether the empty material position left by taking away the first material tray on the feeder is loaded with a second material tray, and the second material tray is a feeder tray corresponding to the first material tray. If yes, proceed to the next step, otherwise, do not act;

[0084] S15: Check whether the first material tray is in a confirmed removal state, and if so, issue a reminder to continue refilling, otherwise, issue an alarm;

[0085] Through the above two steps, it can be ensured that the second material tray has been placed on the vacant space left after the first material tray is removed; it should be noted that S14 can be between S11 and S12, between S12 and S13, or after S13, and this scheme can be implemented, and the schemes corresponding to the three positions all fall within the protection scope of this application.

[0086] Preferably, the method of monitoring whether the first material tray in the first set area on the feeder is removed by the first monitoring unit is as follows:

[0087] A tray holder is arranged on the feeder, and a tray placement position for placing a first tray and a first monitoring unit for detecting whether there is a first tray at the tray placement position are provided on the tray holder, and whether the first tray on the feeder is removed is determined based on the detection data of the first monitoring unit.

[0088] Preferably, if the first monitoring unit is used to monitor whether the first material tray in the feeding area on the feeder is taken away, the method for determining whether the data of the material tray being scanned by the code scanning unit corresponding to the material tray storage area is received within the set time is:

[0089] Configure a barcode scanner or a second monitoring unit as the set barcode scanning unit;

[0090] The timing starts when the first monitoring unit detects that the first material tray is taken away from the feeder. If no scanning information feedback is received from the barcode scanner or the second monitoring unit within the set time after the timing starts, it is considered to be timed out and an alarm is issued, otherwise it is considered not to have timed out;

[0091] At this time, there is no need for manual additional code scanning operation to determine the initial timing time, and the first detection unit can directly perform this step, saving manpower.

[0092] Embodiment 3

[0093] A chip placement machine material refill error prevention system is applied to the chip placement machine material refill error prevention method as described in the first embodiment above, such as Figure 3 As shown, the system includes a feeder 10, a code scanning unit 11, a tray storage unit 12 and a control host 13;

[0094] By manually monitoring whether the first material tray in the loading area on the feeder 10 is taken away; the control host 13 is used to determine whether the data of the material tray being scanned by the scanning unit 11 corresponding to the material tray storage area of ​​the material tray storage unit 12 is received within the set time, otherwise an alarm is issued, and if yes, the material tray ID information is obtained by identifying the data of the material tray scanning code, and whether it is the first material tray is determined according to the material tray ID information, if yes, the first material tray is determined to be in a confirmed removal state, otherwise an alarm is issued;

[0095] By applying the system of the present application, by manually monitoring whether the material tray on the feeder has been removed and performing delayed scanning to confirm, it can be ensured that the material tray has been removed from the feeder, thereby reducing the probability of misplacement due to failure to leave space for material refilling on the feeder, and the feeding processing is safer.

[0096] Preferably, the method for judging whether the data of scanning the material tray by the code scanning unit corresponding to the material tray storage area is received within the set time is as follows: configuring a code scanning gun or a second monitoring unit as the set code scanning unit; manually scanning the first material tray taken away and starting the timing from the time of scanning, if within the set time after the timing starts, no scanning information feedback is received from the code scanning gun or the second monitoring unit, it is determined to be timed out and an alarm is issued, otherwise it is determined not to be timed out;

[0097] Preferably, the tray storage unit adopts a scanning container or a penetration rod, and the internal storage space of the scanning container or the material storage space of the penetration rod is the tray storage area; the tray ID information is obtained by identifying the data of the tray scanning code: the scanning container or the penetration rod is scanned by a scanning gun to identify the ID and verify it. If the verification passes, the barcode of the tray to be placed or has been placed is scanned by the scanning gun to obtain the tray ID information; if the verification fails, an alarm is issued;

[0098] Alternatively, the tray storage unit adopts a code scanning shelf, the code scanning shelf is bound to a single or multiple feeders, and the multiple rows of storage slots on the code scanning shelf constitute the tray storage area; the storage slots on the code scanning shelf are provided with a second monitoring unit; the tray ID information is obtained by identifying the data of the tray code scanning: when the tray is placed into the storage slot of the code scanning shelf, the second monitoring unit is triggered to scan the first tray.

[0102] The control host 23 is used to determine whether the data of scanning the material tray by the scanning unit 21 corresponding to the material tray storage area of ​​the material tray storage unit 22 is received within a set time after the first material tray is taken away. Otherwise, an alarm is issued. If yes, the material tray ID information is obtained by identifying the data of the material tray scanning code, and whether it is the first material tray is determined according to the material tray ID information. If yes, it is determined that the first material tray is in a confirmed removal state, otherwise an alarm is issued;

[0103] By using the system of the present application, the first monitoring unit 200 is used to monitor whether the material tray on the feeder has been removed, and a delayed code scanning confirmation is performed to ensure that the material tray has been removed from the feeder, thereby reducing the probability of misplacement due to failure to leave space for material refilling on the feeder, and the feeding processing is safer.

The chip placement machine material feeding error prevention method according to claim 5, characterized in that: A code scanning shelf is configured for storing or temporarily storing material trays, the code scanning shelf is bound to a single or multiple feeders, and multiple rows of material storage troughs on the code scanning shelf constitute a material tray storage area; the second monitoring unit is provided on the material storage trough on the code scanning shelf; The method for obtaining the tray ID information by identifying the data of the tray code scan is as follows: When the material tray is placed into the storage slot of the code scanning shelf, the second monitoring unit is triggered to scan the code of the first material tray.

8. A chip placement machine material refill error prevention system, applied to the chip placement machine material refill error prevention method as claimed in any one of claims 1 to 7, characterized in that: The system includes a feeder, a code scanning unit, a tray storage unit and a control host; Monitoring whether the first material tray in the loading area on the feeder is taken away by a first monitoring unit or manually; if the first monitoring unit is used to monitor whether the first material tray is taken away, the feeder is provided with the first monitoring unit; The control host is used to determine whether the data of the scanning unit corresponding to the tray storage area of ​​the tray storage unit scanning the tray is received within a set time after the first tray is taken away. Otherwise, an alarm is issued. If yes, the tray ID information is obtained by identifying the scanned data of the tray, and whether it is the first tray is determined according to the tray ID information. If yes, it is determined that the first tray is in a confirmed removal state, otherwise an alarm is issued.

9. The chip placement machine feeding error prevention system according to claim 8, characterized in that: If the first monitoring unit is used to monitor whether the first material tray in the feeding area on the feeder is taken away, it is judged whether the data of the material tray being scanned by the code scanning unit corresponding to the material tray storage area is received within the set time. The following is adopted: a code scanning gun or a second monitoring unit is configured as the set code scanning unit; the timing starts from when the first monitoring unit detects that the first material tray is taken away from the feeder. If the code scanning information feedback is not received from the code scanning gun or the second monitoring unit within the set time after the timing starts, it is determined that the timeout has occurred and an alarm is issued, otherwise it is determined that the timeout has not occurred; If manual monitoring is used to determine whether the first tray in the loading area on the feeder has been taken away, the following is used to determine whether data from the scanning unit corresponding to the tray storage area is received within the set time: a scanning gun or a second monitoring unit is configured as the set scanning unit; the first tray that has been taken away is manually scanned and timing begins at the time of scanning; if no scanning information feedback is received from the scanning gun or the second monitoring unit within the set time after the start of timing, it is deemed to be timed out and an alarm is issued; otherwise, it is deemed not to have timed out.
