Referring to fig. 1 and 2, an embodiment of the present application provides a material conveying apparatus, which includes a feeding device 10, a conveying line (not shown), a grabbing device (not shown), and a detecting device (not shown). The transfer line includes a plurality of transfer devices 20 capable of independently controlling the feed rate of downstream feed movement. The plurality of transfer devices 20 can sequentially move to reach the feeding station a, and alternately pass through n cache sections C and n grabbing stations B downstream along a first preset track. That is, the 1 st buffer segment C, the 1 st gripping station B, the 2 nd buffer segment C, the 2 nd gripping station B … … nth-1 st buffer segment C, the n-1 st gripping station B, the nth buffer segment C, and the nth gripping station B are sequentially arranged from upstream to downstream. The loading device 10 is used for loading a material 100 (see fig. 3) onto a transfer device 20 reaching a loading station a. The gripping devices are used for gripping the material 100 on each transfer device 20 at any gripping station B and transferring the gripped material 100 to the inspection station. The inspection device is used to inspect each of the materials 100 transferred to the inspection station. Wherein n is a positive integer greater than or equal to 1.

It should be noted that the gripping device may include a plurality of gripping manipulators disposed in one-to-one correspondence with the plurality of gripping stations B, and each gripping manipulator grips and transfers the material 200 on each transfer device 20 corresponding to the gripping station B. Of course, in other embodiments, the number of the grabbing manipulators may be less than the number of grabbing stations B, that is, the grabbing manipulators are shared by the partial grabbing stations B, so long as the grabbing and transferring of the material 200 at each grabbing station B can be achieved, which is not limited herein. Similarly, the plurality of detection stations may also include a plurality of detection stations disposed in one-to-one correspondence with the plurality of grabbing stations B, each detection station being configured to receive the material 200 transferred by the corresponding grabbing station. Of course, in other embodiments, the number of detecting stations may be less than the number of grabbing stations B, that is, the number of grabbing stations B may be less than the number of grabbing stations B, so long as the detecting stations are capable of receiving and detecting the material 200 transferred by each grabbing station B, which is not limited herein.

It should be noted that the material may be a pole piece, a diaphragm, or a lamination unit formed by combining a pole piece and a diaphragm. Of course, other types of products are possible and are not limited herein.

In the above-mentioned material conveying apparatus, in actual use, each transfer device 20 of the conveying line sequentially passes through the loading station a one by one, and receives the material 100 transferred by the loading device 10 at the loading station a. Each transfer device 20 moves downstream after receiving the material 100 at the loading station a and sequentially passes through n buffer sections C and n gripping stations B alternately with each other. When a predetermined number (i.e., 4 as shown in the drawing) of transfer devices 20 loaded with materials 100 reach an mth gripping station B, the gripping devices are controlled to simultaneously grip the materials 100 on each transfer device 20 on the mth gripping station B, and the gripped predetermined number of materials 100 are transferred to a detection station, wherein m is a positive integer, and m is 1.ltoreq.n. That is, the transfer device 20 continuously receives the material 100 at the loading station a, and sequentially moves to each of the downstream gripping stations B, and the gripping device grips a predetermined number of the material 100 at each of the gripping stations B and transfers the material to the detecting station.

After the preset number of materials 100 on each transfer device 20 on the mth gripping station B are gripped by the gripping devices and transferred to the detection station, the detection station detects the preset number of materials 100. If the predetermined amount of material 100 is not defective, the predetermined amount of material 100 is transferred downstream (e.g., onto a lamination table for lamination). If the preset number of materials 100 has defective products, the defective products are removed, and the grabbing device is controlled to perform material supplementing (that is, the materials 100 with the same number as the defective products are grabbed again to the corresponding positions of the detection stations, so that the number of the materials 100 in the detection stations is the preset number).

During the feeding process: the respective transfer devices 20 of the mth buffer section C are controlled to adjust the feeding speed to reduce the interval therebetween, thereby ensuring that the transfer devices 20 that enter the mth buffer section C from upstream (since the upstream incoming material of the material 100 is continuously entered into the mth buffer section C, there are transfer devices 20 that continuously enter the mth buffer section C), and only the transfer devices 20 that carry the material 100 in the mth buffer section C equal to the number of the detected defective products are allowed to enter the mth gripping station B. Then, the gripping device grips each material 100 (the same number as defective products) on the transfer device 20 on the mth gripping station B, and transfers to the corresponding position of the detection station. The replenished materials 100 are then tested. If the defective product exists in the detection station, executing the material supplementing process again; if no defective products are detected, each material 100 of the detection station is transferred to the downstream so that the grabbing device transfers the preset number of materials 100 to the detection station again for detection.

In this way, since the control of the feeding speed of each transfer device 20 of the conveying line is independent from each other, in the normal operation process, each transfer device 20 moves downstream at the same preset feeding speed, and sequentially passes through each buffer section C and each grabbing station B, so as to realize group transfer of the materials 100 to each grabbing station B (the number of each group is the preset number) for grabbing by the grabbing device and transferring to the detection station for detection. In the process of material replenishment, the feeding speed of the transfer devices 20 of the corresponding buffer section C is controlled, so that the distance between the transfer devices 20 in the corresponding buffer section C is reduced, on one hand, the buffer section C can accommodate the transfer devices 20 continuously entering the buffer section C, and on the other hand, only the transfer devices 20 with the same number of defective products as the transfer devices 100 are allowed to enter the corresponding grabbing station B, so that the grabbing devices grab and transfer to the detection station to realize material replenishment.

That is, each cache sector C includes a first state and a second state. When the buffer section C is in the first state, each transfer device 20 in the buffer section C moves downstream at a preset feed speed so that the loaded material 100 is gripped and transferred by the gripping device when reaching the corresponding gripping station B. When the buffer section C is in the second state, the respective transfer devices 20 in the buffer section C increase or decrease the spacing between the respective transfer devices 20 in the buffer section C by adjusting the respective feeding speeds. Thus, when no material replenishment is required, each buffer section C is in the first state, i.e., each transfer device 20 downstream of the loading station a moves downstream at a predetermined speed, and the intervals between the transfer devices 20 are kept equal. In the process of feeding, each transfer device 20 in the corresponding buffer section C is first adjusted to a feeding speed (other buffer sections C and the transfer devices 20 of each gripping station B can be kept in a first state), so that the space between each transfer device 20 in the buffer section C is reduced, on one hand, the buffer section C can accommodate the transfer devices 20 continuously entering the buffer section C, and on the other hand, only the transfer devices 20 with the same number of defective products as the transfer devices 20 loaded with the materials 100 are allowed to enter the corresponding gripping stations B, so that the gripping devices can grip and transfer to the detection stations to realize feeding. After the gripping device transfers the supplementary material 100, each transfer device 20 in the buffer section C further adjusts its feeding speed, so as to increase the interval between the transfer devices 20 until the interval between the transfer devices 20 returns to the state before the material supplementing process.

In the embodiment of the present application, each transfer device 20 can also pass through the blanking station D located downstream of the n gripping stations B. And, the transfer device 20 reaching the blanking station D can return to the feeding station a along the second preset track, thereby realizing the cyclic utilization of the transfer device 20 and being beneficial to improving the production efficiency. That is, each transfer device 20 receives the material 100 at the loading station a, moves downstream, sequentially passes through each buffer section C and each gripping station B (the material 100 loaded at one gripping station B is gripped by the gripping device) until reaching the unloading station D, and returns from the unloading station D to the loading station a along the second predetermined trajectory, thereby circulating. Further, the first preset track and the second preset track are not overlapped, so that the transfer device 20 returned to the feeding station A from the feeding station D and the transfer device 20 moved to the feeding station D from the feeding station A are prevented from interfering. Optionally, the conveying line includes an upper layer and a lower layer, and the transfer device 20 rises to the upper layer at the loading station a, moves along the upper layer and passes through each buffer section C and each grabbing station B, and reaches the unloading station D. At the blanking station D, the transfer device 20 descends to the lower layer and returns to the feeding station a along the lower layer, thereby circulating.

In an embodiment of the present application, the conveyor line further includes a mounting base, and each transfer device 20 is movably connected to the mounting base. The mounting base is provided with an electromagnetic element, and each transfer device 20 is provided with a magnetic element. The electromagnetic element electromagnetically induces the magnetic element to drive each transfer device 20 to move on the mount. That is, the transfer line adopts a magnetic levitation transfer line, and the feed movement speed of each transfer device 20 can be controlled individually. The specific structure of the transfer device 20 and the assembly structure of the transfer device 20 and the mounting base may be any known technology, and is not limited herein.

Please refer to fig. 16 and 17. The application also provides a material conveying method using the material conveying equipment, which comprises the following steps:

s10, controlling each transfer device 20 of the conveying line to pass through the feeding station A one by one and receiving the materials 100 at the feeding station A.

S20, the transfer device 20 passing through the feeding station A moves downstream at a preset feeding speed and passes through n cache sections C and n grabbing stations B. Wherein, in the upstream to downstream direction, the buffer sections C and the gripping stations B are alternately arranged with each other.

S30, when a preset number of transfer devices 20 loaded with materials 100 reach an mth grabbing station B, controlling the grabbing devices to simultaneously grab the materials 100 on each transfer device 20 on the mth grabbing station B, and transferring to a detection station for detection; wherein m is a positive integer, and m is more than or equal to 1 and less than or equal to n.

And S40, detecting each material 100 on the detection station.

If no defective products are detected in the materials 100 on the detection station, the materials 100 on the detection station are transferred downstream, and the steps S10 to S40 are continuously and circularly executed.

If defective products are detected in the materials 100 on the detection station, rejecting the defective products, and executing a material supplementing step S41, grabbing and transferring a corresponding amount of materials 100 to the detection station again at an mth grabbing station B through the material supplementing step S41.

Further, the feeding step S41 includes:

s411, controlling the transfer devices 20 positioned in the mth buffer section C to reduce the distance between the transfer devices by adjusting the feeding speed, so that the mth buffer section C can continuously accommodate the transfer devices 20 input from the upstream, and only the transfer devices 20 loaded with the materials 100, the quantity of which is equal to that of defective products, are allowed to enter the mth grabbing station B from the mth buffer section C;

s412, controlling the grabbing devices to grab the materials 100 (the number of the materials 100 is equal to the number of defective products) on each transferring device 20 of the mth grabbing station B at the same time, and transferring to the detection station, so as to realize material supplementing.

S413, controlling the transfer device 20 located in the mth buffer section C to restore the distance between them by adjusting the feeding speed.

In the embodiment, in the feeding step, the step S412 is performed and then the step S40 is performed again, so that the fed material 100 is detected. If no defective products are detected in the supplementary materials 100, each material 100 on the detection station is transferred downstream, and steps S10 to S40 are cyclically executed. If the defective products in the materials 100 are detected, the defective products are removed, and the material supplementing step is executed again, namely the materials 100 are supplemented to the detection station again until the defective products of the materials 100 in the detection station are not detected.

In the embodiment of the present application, in step S20, a predetermined number of transfer devices 20 are fed to each gripping station B every time a predetermined period of time L elapses. At the mth gripping station B, the time period of the interval between gripping the materials 100 on each transfer device 20 at the mth gripping station B in step S30 is n×l every two times. That is, on the same gripping station B, the gripping devices grip the material 100 on each of the transfer devices 20 on the gripping station B for n×l of time interval between the next gripping of the material 100 on each of the transfer devices 20 on the gripping station B, so that it can be ensured that each of the gripping stations B moves the transfer device 20 carrying the material 100 at a preset rate to the gripping station B for n×l of time interval.

Further, when the detecting station detects that there is a defective product in the material 100 transferred by the mth grabbing station B, on the mth grabbing station B, the duration of the interval between the material 100 on each transferring device 20 grabbing the mth grabbing station B in the step S30 and the material 100 on each transferring device 20 grabbing the mth grabbing station B in the step S41 for supplementing is 3×l, so that the transferring device 20 on the mth grabbing station B can be emptied first by using the duration of 3×l, and then the transferring devices 20 carrying the material 100 in the mth buffer section C, which are the same as the number of defective products, reach the corresponding position of the mth grabbing station B for grabbing and transferring by the grabbing device. At the same time, 2×4 transfer devices 20 loaded with the material 100 are routed through the mth gripping station B and conveyed downstream for the 3×l period.

It should be noted that, after the one-time feeding step is performed, the timing of reaching the downstream gripping station B by the downstream transfer device 20 is affected, and since each transfer device 20 can independently control the feeding speed, the time for reaching the position can be prolonged or shortened by controlling the manner of changing the distance of the transfer device 20 in the corresponding downstream buffer section C, so as to match the gripping action of the gripping device, and ensure that each downstream gripping station B can sequentially perform the conveying and gripping actions of the material 100.

Referring to fig. 3 to 9, for example, when n is equal to 2 (i.e. the number of the buffer sections C and the number of the grabbing stations B are two), the preset duration L is 1S, and the preset number is 4, first, in a time period from 0S to 2S, each transfer device 20 receives the material 100 through the feeding station a one by one and moves downstream at a preset feeding speed. At 2s, four transfer devices 20 loaded with the material 100 reach the 1 st gripping station B, and at this time, the gripping devices grip the material 100 on the four transfer devices 20 of the 1 st gripping station B and transfer to the inspection station.

In the period of 2s to 3s, each transfer device 20 continues to move downstream at the preset feed speed. In this process, if each of the materials 100 at the inspection station is inspected as a good, each of the transfer devices 20 continues to move downstream at the preset feed speed for a period of 3s to 4 s. At 4s, four transfer devices 20 loaded with the material 100 reach the 1 st gripping station B, and at this time, the gripping devices grip the material 100 on the four transfer devices 20 of the 1 st gripping station B and transfer to the inspection station.

In the period of 4s to 5s, each transfer device 20 continues to move downstream at the preset feed speed. In this process, if each of the materials 100 at the inspection station is inspected as a good, each of the transfer devices 20 continues to move downstream at the preset feed speed for a period of 5s to 6 s. At 6s, the gripping device grips the material 100 on the four transfer devices 20 of the 1 st gripping station B, and transfers the gripped material 100 to the detection station for detection.

At the time of 5.25s, the four transfer devices 20 loaded with the materials 100 reach the 2 nd grabbing station B, and at this time, the grabbing devices grab the materials 100 on the four transfer devices 20 of the 2 nd grabbing station B and transfer to the detection station for detection.

In the period of 6s to 7s, each transfer device 20 continues to move downstream at the preset feed speed. In this process, if each of the materials 100 at the inspection station is inspected as a good, each of the transfer devices 20 continues to move downstream at the preset feed speed for a period of 7s to 8 s. And so on, the gripping devices grip and transfer the material 100 on the four transfer devices 20 of the 1 st gripping station B at the time of 2s, 4s, 6s and 8s … …, that is, the gripping devices grip and transfer the material 100 at the 1 st gripping station B every 2 seconds. Meanwhile, the gripping devices grip and transfer the material 100 on the four transfer devices 20 of the 2 nd gripping station B at the time of 5.25s, 7.25s, 9.25s, 11.25s … …, that is, the gripping devices grip and transfer the material 100 at the 2 nd gripping station B every 2 seconds.

Referring to fig. 10 to 15, when it is detected that there is a defective product in the material 100 transferred from the 1 st gripping station B to the detecting station at the 3 rd time, each transfer device 20 in the 1 st buffer section C is adjusted to reduce the pitch by adjusting the feeding speed in the 3 rd to 4 th time period so as to be able to accommodate the transfer device 20 inputted from the loading station a (in this process, the transfer devices 20 at other positions are moved downstream at the preset feeding speed). In the time period of 4s to 5s, the respective transfer devices 20 in the 1 st buffer section C are reduced in pitch by adjusting the feed speed, so that on the one hand, it is convenient to accommodate the transfer devices 20 inputted by the loading station a while only allowing the same number of transfer devices 20 as defective products from the 1 st buffer section C to enter the 1 st gripping station B (in this process, any of the transfer devices 20 at other positions moves downstream at the preset feed speed). And, at 5s, the gripping device grips the material 100 on the transfer device 20 of the 1 st gripping station B and transfers to the inspection station to replace defective products (i.e., supplementary materials).

In the period of 5s to 5.5s, the respective transfer devices 20 in the 1 st buffer section C restore the pitch by adjusting the feed speed (in this process, the transfer devices 20 at other positions move downstream at the preset feed speed). At 5.25s, the gripping device grips the material 100 on the four transfer devices 20 on the 2 nd gripping station B and transfers to the inspection station … ….
