When the feeding detection equipment 1 generates a bad signal, the feeding identification device 13 obtains the slide block code of the slide block jig 12 at the feeding detection station 11, and the control system 4 marks the slide block code as a bad slide block code.
As shown in fig. 4, the processing equipment 2 has a processing station 22, a plurality of tray jigs 21, and a processing identification device 23, the processing station 22 is used for processing good products into finished products, each tray jig 21 is provided with a tray label with a tray code, the tray jig 21 is provided with a plurality of point locations, each point location can place one good product, the tray jig 21 at a first junction is conveyed to the processing station 22 after being filled with the materials, the processing station 22 is provided with a processing jig 221 for positioning the good products, and the number of the point locations of the processing jig 221 is the same as that of the tray jig 21. Processing recognition device 23 installs in first handing-over department, when unloaded tray tool 21 moves first handing-over department, processing recognition device 23 acquires tray tool 21's tray code, record the incident and trace back the circulation as new round and begin this moment, control system is automatic for new circulation serial number, good product material is placed according to tray tool 21's point position serial number in proper order to material loading arm 14, move to machining position 22 after tray tool 21 fills up the material, the finished product of machining tool 221 and the good product material of tray tool 21 are replaced one-to-one, move to second handing-over department after tray tool 21 fills up the finished product, machining position 22 processes the good product material in the machining tool 221. It should be noted that the pallet jigs 21 in the processing equipment 2 are arranged in sequence according to the size of the pallet code, the good-quality material of the previous pallet jig 21 is processed into a finished product and then is put into the next pallet jig 21, when a bad signal occurs in the product detection station, the pallet code of the pallet jig 21 at the current second joint is obtained as the to-be-processed pallet code, and the previous pallet code of the to-be-processed pallet code is marked as the bad pallet code.
In some embodiments of the present invention, the number of the tray jigs 21 is 8, the serial numbers of the points are #1 to #8, the number of the tray jigs 21 is n, and the tray codes are 1# to n #. When the empty tray jig 21 enters the first junction, the processing and identifying device 23 collects the tray code of the tray jig 21, at this time, the recorded event is used as a new round of tracing cycle to start, and the control system 4 automatically numbers the new cycle.
After the new cycle begins, the feeding mechanical arm 14 grabs the good materials from the slider jig 12 and transfers the good materials to the pallet jig 21 at the first junction, at this time, the first transfer occurs, 8 good materials are sequentially placed on 8 points of the pallet jig 21, the tray jig 21 is operated to the processing station 22, 8 good-quality materials and 8 finished products of the processing station 22 are replaced one by one, at this time, the second transfer is carried out, the 8 good-quality materials carried by the tray jig 21 are replaced by finished products of the good-quality materials carried by the last tray jig 21, the association relationship between the transferred finished products and the tray jig 21 is changed, however, the order of the positions of the finished products on the tray jig 21 is not changed, the finished products enter the second junction along with the tray jig 21, the finished product detection equipment 3 completes the final detection, and the cycle is terminated after all the finished product detections are completed.
When a defective signal occurs at the finished product detection station, the control system 4 modifies the corresponding relationship between the transferred finished product and the tray jig, for example, if the tray code read by the finished product identification device is #3, the control system modifies the defective tray code to #2, and by analogy, when the processing equipment detects a defect, the tray code of the tray jig where the defective finished product is located can be traced.
In the preferred embodiment of the present invention, the pallet fixture 21 is cycled between a first interface, the processing station 22, and a second interface, marking the last pallet code as a bad pallet code when the code to be processed is the first pallet code. For example, the number of the tray jigs is 4, the last tray code is 4#, and if the tray code read by the finished product identification device is 1#, the control system corrects the bad tray code to 4 #.
As shown in fig. 5 and 6, the finished product detecting device 3 has a feeding position, a finished product detecting station, a turntable device 31, a finished product mechanical arm 32 and a finished product identifying device 33, the finished product detecting station is used for detecting whether a finished product is defective, the turntable device 31 is provided with a plurality of positioning seats, each positioning seat can pass through the feeding position and the finished product detecting station, the turntable device 31 can transport the finished product from the feeding position to the lower part of the finished product detecting station for detection, a fully loaded tray jig 21 is parked at a second junction to wait for the finished product to be taken out, the finished product identifying device 33 is installed at the second junction, the tray jig 21 passes through the finished product identifying device 33 when entering the finished product detecting device 3, the finished product identifying device 33 reads the tray code of the tray jig 21, at this time, an event is recorded as a new cycle, and the control system 4 automatically adopts a new cycle number. After a new cycle starts, the finished product mechanical arm 32 grabs the finished product from the tray jig 21 and transfers the finished product to the turntable device 31, at this time, a third transfer occurs, the finished product rotates along with the turntable device 31 and passes through the finished product detection station, and after all the finished product detection on the tray jig 21 is completed, the cycle is terminated.
When the finished product detection station sends a bad signal, the control system 4 traces back the bad point location serial number according to the step number of the turntable device 31, and binds the bad point location serial number with the bad tray code. For example, if the tray code read by the product reading device 33 is 3#, when the turntable device 31 rotates for 2 steps, the product at the #1 point arrives at the product detection station, and so on, when the turntable device 31 rotates for 3 steps, the product at the #2 point arrives at the product detection station, when the product detection station sends a failure signal, if the number of the rotation steps of the turntable device 31 is 6, the product at the #5 point is a failure product, that is, the number of the failure point is #5, and the control system 4 identifies that the failure occurs at the #5 point of the tray fixture positioned to the tray code of 2 #.
Because the tray jig 21 fully loaded with finished products waits before entering the finished product inspection device 3, a situation that the tray jig 21 is empty or the relationship between the finished products and the tray jig 21 is changed due to human interference may occur during the waiting process. Therefore, the empty position of the tray jig 21 needs to be detected.
In some embodiments of the invention, the finished product inspection apparatus 3 is provided with a feed buffer 34 and a transfer device, the feed buffer 34 being used for parking individual finished products, the transfer device being used for feeding the finished products on the feed buffer 34 to a positioning seat of a feed station, the feed station being provided with a feed vacancy sensor 35 and an additional vacancy sensor 36. The feed vacancy sensor 35 has a higher priority than the additional vacancy sensor 36, i.e. the rotary table means 31 is moved forward one step when the feed vacancy sensor 35 detects the presence of finished products, and the rotary table means 31 is not moved when the feed vacancy sensor 35 detects the absence of finished products. The purpose of the additional vacancy sensor 36 is to avoid a vacancy misjudgment, when the feed vacancy sensor 35 detects the presence of a finished product, but the additional vacancy sensor 36 detects the absence of a finished product, when the rotary table device 31 has moved forward by one step, it is necessary to reduce the number of steps of the rotary table device 31 by 1, that is, the rotary table device 31 rotates backward by one step and returns to the original position. When the feeding vacancy sensor 35 or the additional vacancy sensor 36 detects that no finished product exists, the control system 4 identifies the vacancy point location serial number according to the picking times of the finished product mechanical arm 32 and the detection signal of the vacancy sensor, and skips over the vacancy point location serial number when tracing the bad point location serial number.
For example, the finished product identifying device 33 reads the tray code of the tray fixture, at this time, a new round of tracing back cycle is started, the finished product mechanical arm 32 takes one finished product from the tray fixture 21 each time, when the feeding vacancy sensor 35 and the additional station sensor 36 both detect that a finished product exists, the turntable device 31 rotates forward 1 step, the finished product at the #1 point is transported forward one step from the feeding position, when the finished product mechanical arm 32 takes a finished product from the tray fixture 21 for the 4 th time, and the feeding vacancy sensor 35 or the additional station sensor 36 detects that no finished product exists, the #4 point is a vacancy, that is, the vacancy point number is #4, when the product detection station sends a failure signal, if the rotating step number of the turntable device 31 is obtained to be 6, the #4 is skipped when the failure point number is obtained, that the failure point number is #6, the control system 4 identifies that the #4 positioned to the tray fixture with the tray code of 2# is a vacancy, and the #6 point of the tray jig of the tray code 2# is defective.
In a preferred embodiment of the present invention, the finished product detecting apparatus 3 is further provided with a detection buffer area 37, the detection buffer area 37 is located between the second junction and the feeding buffer area 34, the finished product mechanical arm 32 takes out a finished product from the tray jig 21 and places the finished product in the detection buffer area 37, the detection buffer area 37 is provided with a buffer vacancy sensor 38 for detecting whether the finished product exists or not, the finished product is transferred from the detection buffer area 37 to the feeding buffer area 34, the buffer vacancy sensor 38, the feeding vacancy sensor 35 and the additional vacancy sensor 36 jointly detect whether the tray jig 21 is vacant, if any one vacancy sensor detects that the finished product does not exist, the corresponding point location serial number is a vacancy point serial number, and vacancy misjudgment is avoided.
In some embodiments of the present invention, the finished product detecting apparatus 3 is provided with a discharging position, more than two finished product detecting stations of different types, and a discharging mechanical arm 39, the discharging mechanical arm 39 is used for conveying finished products at the discharging position, when a defective signal occurs at the finished product detecting station, the control system obtains the number of steps of the current turntable device to trace back the serial number of the defective point, and when a finished product with the serial number of the defective point rotates to the discharging position, the discharging mechanical arm 39 is controlled to take out the finished product and place the finished product in the defective product box 300 of the corresponding type.
