DETAILED DESCRIPTION

[0028] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0029] The following describes the production reporting device for industrial MES according to an embodiment of the present application in conjunction with the accompanying drawings.

[0030] like Figure 1 and Figure 2 As shown, the production reporting device for industrial MES of the embodiment of the present application may include a first transmission structure 100, a second transmission structure 200, a movable limit device 300, a buffer transfer device 400, a piezoelectric counter 500, a photoelectric sensor 600 and an operating table 700.

[0031] The first transmission structure 100 is mounted on the second transmission structure 200 , and the transmission directions of the first transmission structure 100 and the second transmission structure 200 are opposite, that is, the discharge end of the first transmission structure 100 and the discharge end of the second transmission structure 200 are located on the same side.

[0032] The movable limiting device 300 can be rotatably disposed at the discharge end of the first transmission structure 100 to block the discharge of the workpiece on the first transmission structure 100 .

[0033] The buffer transfer device 400 is mounted on the feed end of the second transmission structure 200. Figure 4 and Figure 5 As shown, the buffer transfer device 400 includes a column frame 410 , a rotatable and resetting rotating arm 420 , a bearing structure 430 , a trigger head 440 and a tension spring 450 .

[0034] The column frame 410 is arranged on the feed end of the second transmission structure 200 through the mounting base plate 201, the middle part of the rotating arm 420 is rotatably arranged on the column frame 410, and the two ends of the tension spring 450 are respectively connected to the rotating arm 420 and the column frame 410.

[0035] The bearing structure 430 is disposed at one end of the rotating arm 420 , and is used to push up the movable limiting device 300 , so that the workpiece on the first transmission structure 100 is transmitted to the bearing structure 430 .

[0036] The trigger head 440 is disposed on the other end of the rotating arm 420 to trigger the piezoelectric counter 500 when the supporting structure 430 sinks due to the gravity of the workpiece.

[0037] It should be noted that when the workpiece is transferred from the first transmission structure 100 to the supporting structure 430, the gravity is greater than the tension of the tension spring 450, so that the workpiece presses down the supporting structure 430, causing the rotating arm 420 to rotate, and when the supporting structure rotates downward, the trigger head 440 triggers the piezoelectric counter 500, and the workpiece slides onto the second transmission structure 200.

[0038] The photoelectric sensor 600 is disposed on the transmission path of the second transmission structure 200 , and the piezoelectric counter 500 and the photoelectric sensor 600 are both electrically connected to the operating platform 700 .

[0039] Specifically, the workpiece is transferred from the first transfer structure 100 to the movable stopper 300 and is blocked by the movable stopper 300. Figure 6 As shown, the rotating arm 420 in the buffer transfer device 400 rotates under the tensile action of the tension spring 450, and the supporting structure 430 rotates along with the rotating arm 420 and pushes up the movable limiting device 300. At this time, the workpiece is discharged from the discharge end of the first transmission structure 100 and falls onto the supporting structure 430.

[0040] When the workpiece falls onto the supporting structure 430 , the workpiece presses down the supporting structure 430 to rotate the rotating arm 420 . Meanwhile, the supporting structure 430 no longer pushes up the movable limiting device 300 , so that the movable limiting device 300 again limits and blocks the first transmission structure 100 .

[0041] When the rotating arm 420 continues to rotate, Figure 7As shown, the supporting structure 430 drives the workpiece to descend, and the trigger head 440 triggers the piezoelectric counter 500. After being squeezed and triggered by the trigger head 440, the piezoelectric counter 500 starts counting and transmits the counting data to the operating table 700. When the supporting structure 430 descends, the workpiece slides from the supporting structure 430 to the second transmission structure 200. During the transmission process of the workpiece through the second transmission structure 200, the photoelectric sensor 600 recognizes the workpiece again and transmits the recognition signal to the controller. The controller completes the counting of one workpiece based on the dual detection of the counting data of the piezoelectric counter 500 and the recognition signal of the photoelectric sensor 600.

[0042] After the workpiece on the supporting structure 430 is detached, the tension spring 450 starts to drive the rotating arm 420 to reset due to the tension effect, so that the supporting structure 430 rises and resets, and pushes up the movable limiting device 300 again, so that the subsequent workpiece is transferred to the supporting structure 430 again, and this cycle repeats.

[0043] In one embodiment of the present application, Figure 3 As shown, the movable limiting device 300 includes a limiting plate 310 , a fixed shaft 320 and a torsion spring 330 .

[0044] Among them, a mounting seat 101 is provided on the first transmission structure 100, a fixed shaft 320 is provided on the mounting seat 101, a limit plate 310 is rotatably provided on the fixed shaft 320, a torsion spring 330 is sleeved on the fixed shaft 320, and two ends of the torsion spring 330 are respectively connected to the limit plate 310 and the mounting seat 101.

[0045] It should be noted that when the limit plate 310 is lifted up, the torsion spring 330 is in a torsion state. When the limit plate 310 loses the upper support of the supporting structure 430, the resetting of the torsion spring 330 drives the limit plate 310 to reset, thereby blocking the workpiece on the first transmission structure 100.

[0046] To clearly explain the previous embodiment, in one embodiment of the present application, a first blocking plate 311 is provided on the side of the limiting plate 310 close to the feed end of the first transmission structure 100, and a second blocking plate 312 is provided on the side of the limiting plate 310 close to the discharge end of the first transmission structure 100. An extended top plate 313 is provided on the second blocking plate 312. When the supporting structure 430 is pushed up, it contacts the top plate 313. An avoidance groove 301 is opened on the limiting plate 310 to avoid the installation position of the torsion spring 330.

[0047] Specifically, when the workpiece is transmitted to the discharge end on the first transmission structure 100, it is blocked by the second blocking plate 312. When the supporting structure 430 pushes up the top plate 313, the limiting plate 310 rotates, and the second blocking plate 312 rises, so that the workpiece falls into the supporting structure 430 under the transmission action of the first transmission structure 100, and the first blocking plate 311 descends to block subsequent workpieces and prevent multiple workpieces from entering the supporting structure 430 at the same time.

[0048] In one embodiment of the present application, the bearing structure 430 includes a bearing bucket 431 , a support frame 432 and rollers 433 .

[0049] The carrying bucket 431 is disposed at the end of the rotating arm 420 , the supporting frame 432 is mounted on the carrying bucket 431 , and the roller 433 is rotatably disposed on the supporting frame 432 to support the top plate 313 .

[0050] It should be noted that when the carrying bucket 431 rotates upward following the rotating arm 420, the support frame 432 supports the roller 433 to push up the top plate 313. When the top plate 313 rotates upward, the roller 433 rotates to reduce the contact and friction between the carrying structure 430 and the top plate 313.

[0051] In one embodiment of the present application, a limit block 401 is disposed on the column frame 410 , and the limit block 401 is located above the rotation axis of the rotating arm 420 and is disposed on the column frame 410 away from the bearing structure 430 .

[0052] It should be noted that when the rotating arm 420 drives the supporting structure 430 to rotate downward, the trigger head 440 rotates upward to contact the piezoelectric counter 500, and the limit block 401 can prevent the trigger head 440 from squeezing the piezoelectric counter 500 too much due to excessive gravity of the workpiece, thereby avoiding damage to the piezoelectric counter 500.

[0053] In addition, a mounting frame 501 is provided on the top of the column frame 410, and the piezoelectric counter 500 is arranged on the mounting frame 501, and the piezoelectric counter 500 is arranged within the rotation area of ​​the trigger head 440, that is, the piezoelectric counter 500 is arranged on the rotation radius of the trigger head 440, thereby ensuring that the trigger head 440 can accurately trigger the piezoelectric counter 500.

[0054] It should be noted that the piezoelectric counter 500 is a device that uses the piezoelectric effect. Its working principle is to sense mechanical changes in the external environment (such as vibration, pressure, etc.) through piezoelectric elements, and then convert these changes into electrical signals. After amplification, shaping and other processing, the electronic circuit performs counting or other forms of data processing. Since the piezoelectric counter 500 is a prior art, it will not be elaborated on in detail.

[0055] In one embodiment of the present application, the first transmission structure 100 and the second transmission structure 200 both include a driving motor, a driving roller, a driven roller and a transmission belt.

[0056] The active roller and the driven roller are rotatably arranged in the transmission belt respectively, and the output end of the driving motor is connected to the active roller.

[0057] As a possible situation, the first transmission structure 100 and the second transmission structure 200 are respectively installed on the same transmission frame to facilitate the installation of the entire device.

[0058] In addition, the transmission direction of the first transmission structure 100 is opposite to the transmission direction of the second transmission structure 200, that is, the driving directions of the driving motor in the first transmission structure 100 and the driving motor in the second transmission structure 200 are opposite, so that the workpiece can be transferred from the discharge end of the first transmission structure 100 through the buffer transfer device 400 to the feed end of the second transmission structure 200.

[0059] In one embodiment of the present application, the operating console 700 has a built-in controller, a data storage module and a wireless communication module, and an external operating interface. The data storage module and the wireless communication module are respectively connected to the controller to store counting data and transmit counting data respectively.

[0060] It is understandable that the data storage module can use optional storage media such as flash memory, SSD, etc., supports large-capacity storage, and the wireless communication module supports multiple wireless communication protocols such as Wi-Fi, Bluetooth, 4G / 5G, etc., and transmits the counting data to the remote monitoring system in real time or displays it through the operation interface.

[0061] It should be noted that the piezoelectric counter 500 and the photoelectric sensor 600 are electrically connected to the controller respectively, wherein the photoelectric sensor 600 is a through-beam sensor, which is arranged on both sides of the second transmission structure 200 to detect the passage of the workpiece.

[0062] As a possible scenario, the operating console 700 also includes an alarm module, which is connected to the controller. When the count is abnormal (i.e., the count of the piezoelectric technology device is inconsistent with the count of the photoelectric sensor 600), an alarm is issued to remind relevant staff to perform maintenance.

[0063] In summary, the production reporting device for industrial MES in the embodiment of the present application, through the cooperation of the buffer transfer device 400 and the movable limit device 300, can keep the workpieces evenly distributed during the transmission process, reduce collisions and accumulation, thereby improving the counting accuracy of the photoelectric sensor 600, and through the combination of the piezoelectric counter 500 and the photoelectric sensor 600 The double counting can ensure the accuracy of the production data, and when achieving accurate reporting, its equipment cost is lower than the reporting cost of RFID tags.
