The present invention also proposes a control method, as shown in fig. 7, which is applied to the test device in the above embodiment, and defines two buffer modules 21 of the test device in the above embodiment as a first buffer module and a second buffer module, respectively, as shown in fig. 7, and the control method includes:
step S10: the first transfer module 31 transfers the tested product in the first test station 1a to the first buffer module, and the second transfer module 32 waits for the product to be put in.
In this embodiment, the first transferring module 31 preferentially transfers the products that have been tested in the first testing station 1a to one buffer module 21, and makes the other buffer module 21 enter a state waiting for feeding; in this embodiment, the first transfer module 31 transfers the product to the first buffer module preferentially, so that the second transfer module 32 enters a state waiting for loading when the first buffer module is loaded, and therefore, enough product can be stored in the first buffer module to supply to the second test station 1b for the next test.
Step S20: when the first buffer module is full, the second transfer module 32 transfers the product in the first buffer module to the second test station 1b for testing.
In this embodiment, the first transfer module 31 continuously transfers the tested products in the first test station 1a to the first buffer module, and when the number of products that can be accommodated in the first buffer module reaches the maximum number upper limit, the first transfer module 31 stops transferring the products to the first buffer module, the first buffer module transfers the products to the second transfer module 32, the second transfer module 32 transfers the products transferred from the first buffer module to the second test station 1b for testing, and the test links in the first test station 1a and the test links in the second test station 1b start to be continuously performed.
Step S30: the first transfer module 31 transfers the tested product in the first test station 1a to the second buffer module for the second transfer module 32 to take.
In this embodiment, since the first buffer module has already transferred the product to the second transfer module 32 and is supplied to the second test station 1b, in order to ensure that the product in the test link in the first test station 1a is continuously supplied into the second test station 1b, the first transfer module 31 is transferred into the empty second buffer module to test the finished product in the first test station 1a, so that when the first buffer module is empty, the product in the second buffer module can be transferred into the second test station 1b through the second transfer module 32 for the next test, thereby avoiding the second test station 1b waiting for product supply, ensuring the continuous operation of the test equipment and improving the operation efficiency of the test equipment.
In an embodiment of the present invention, as shown in fig. 8, when the first buffer module is full, the second transferring module 32 transfers the product in the first buffer module to the second testing station 1b for testing, which includes:
step S21: before the second transfer module 32 takes the material from the first buffer module each time, judging whether the material exists in the first buffer module; if the first cache module is filled with material, judging whether the second cache module is full of material;
in this embodiment, when the first buffer module is full, that is, the first buffer module reaches the upper limit of the number of products to be received, the first buffer module transfers the products in the first buffer module to the second transfer module 32, the second transfer module 32 starts to transfer the products in the first buffer module to the second test station 1b for testing, the products in the first buffer module gradually decrease, and meanwhile, the first transfer module 31 transfers the products in the first test station 1a to the second buffer module, and the products in the second buffer module gradually increase. Therefore, when the second transfer module 32 takes the product into the first buffer module each time, it is determined whether there is material in the first buffer module, that is, whether there is product in the first buffer module, and if there is empty material in the first buffer module, that is, there is no product in the first buffer module, the second transfer module 32 does not perform the action of taking the product into the first buffer module, so as to avoid the second transfer module 32 from performing the invalid operation. If the first buffer module still has the product available and the second buffer module is full, the first transfer module 31 cannot transfer the product tested by the first test station 1a into the second buffer module, so that it is required to determine whether the second buffer module is full.
Step 22: if the second buffer module is full, the second transfer module 32 transfers the product in the second buffer module to the second test station 1b for testing, and the first transfer module 31 puts the product in the first test station 1a into the first buffer module.
In this embodiment, although the first buffer module is still available for use, since the second buffer module is full, that is, the second buffer module reaches the upper limit of the amount of the product received, the first transfer module 31 cannot transfer the product tested by the first test station 1a into the second buffer module, which will cause the first transfer module 31 to enter the idle waiting state, so that the second buffer module transfers the product in the first buffer module to the second transfer module 32, the second transfer module 32 stops taking the product from the first buffer module, and then takes the product from the second buffer module, and the second transfer module 32 supplies the product taken out to the second test module for testing, and resets the first buffer module, so as to improve the utilization rate of the first transfer module 31, and also to ensure that the product is continuously supplied into the second test station 1b in future time, so that the second buffer module transfers the product to the second transfer module 32, and then takes the product from the second buffer module 32.
In an embodiment of the present invention, as shown in fig. 8, after the step of determining whether the second buffer module is full, the method further includes:
Step 23: if the second buffer module is not full, the second transfer module 32 transfers the product in the first buffer module to the second test station 1b for testing, and the first transfer module 31 puts the product in the first test station 1a into the second buffer module.
In this embodiment, when the first buffer module supplies the product to the second buffer module 32, if the first buffer module has product, but the second buffer module is not yet full, i.e. the second buffer module has not yet reached the upper limit of the amount of the product, then in order to make the first buffer module 31 and the second buffer module 32 not idle, the utilization rate of the first buffer module 31 and the second buffer module 32 is improved, the blanking state of the first buffer module and the loading state of the second buffer module are maintained, the second buffer module 32 still transfers the product in the first buffer module to the second test station 1b for testing, and the first buffer module 31 still transfers the product tested by the first test station 1a to the second buffer module until the second buffer module is full or the first buffer module is empty.
In an embodiment of the present invention, as shown in fig. 8, before the second transfer module 32 fetches the product from the first buffer module each time, the step of determining whether there is any material in the first buffer module further includes:
Step 24: if the first cache module is empty, judging whether the second cache module is empty; if the second buffer module has material, the second transfer module 32 transfers the product in the second buffer module to the second test station 1b for testing, and the first transfer module 31 puts the product in the first test station 1a for testing into the first buffer module.
In this embodiment, since the first buffer module is fed in preference to the second buffer module, the first buffer module will be filled first and supply the product to the second transfer module 32 first, when the first buffer module is empty, it means that the second transfer module 32 cannot take the product from the first buffer module 21 any more, at this time, the second buffer module is required to supply the product to the second transfer module 32, and the product of the second buffer module is derived from the product tested by the first test station 1a, when the first buffer module is empty, the first transfer module 31 may not transfer any product to the second buffer module due to the product retesting and other reasons, so at this time, it is required to determine whether the second buffer module is empty, i.e. determine whether the second buffer module is empty. If the second buffer module has products, the products in the second buffer module can be supplied to the second transfer module 32 through the second buffer module, and the products in the second buffer module can be transferred to the second test station 1b for testing through the second transfer module 32, so that the continuous performance of the test link in the second test station 1b is ensured.
In an embodiment of the present invention, as shown in fig. 8, after the step of determining whether there is any material in the second cache module, the method further includes:
step 25: if the second buffer module is empty, the first transfer module 31 puts the tested product in the first test station 1a into the first buffer module.
In this embodiment, when an extreme situation is encountered, such as that the test link in the first test station 1a cannot be successfully performed or the product retest is repeatedly performed, the first test station 1a cannot successfully output the product after the test is completed or the product is qualified, the first transfer module 31 may not be able to transfer the tested product into the first buffer module or the second buffer module all the time, so that the first buffer module and the second buffer module are empty, at this time, the first buffer module needs to be returned to the position of the first transfer module 31 to wait for feeding, and meanwhile, the warning device in the test equipment can prompt the related operator of the test equipment that the equipment is abnormal in operation, so that the related operator can know the equipment operation condition in time, and overhaul and maintain the equipment in time.
It should be noted that the number of products that the first transferring module 31 transfers from the first testing station 1a at a time may be greater than the number that the second transferring module 32 transfers from the buffer module 21 to the second testing station 1b at a time, so that the continuous transfer of the products in the first testing ring station to the products in the second testing station 1b is easier to maintain, which is beneficial to improving the operation efficiency of the testing apparatus. In addition, when the first buffer module and the second buffer module have enough space for storing products or the test links in the first test station 1a and the second test station 1b are performed smoothly, the condition that the first buffer module and the second buffer module are filled simultaneously is generally avoided.
The foregoing description is only of the optional embodiments of the present invention, and is not intended to limit the scope of the invention, and all the equivalent structural changes made by the description of the present invention and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the invention.
