In the above technical solution, the data processing device determines a deviation between an actual position of the display module to be measured on the adjustment platform and a preset position, and a process of the data processing device acquiring the actual position of the display module to be measured on the adjustment platform is specifically described below.
Fig. 2 is a schematic flow chart illustrating another transmission method for a display module according to an embodiment of the present invention. Optionally, referring to fig. 2, before the step 120 of determining the deviation between the actual position of the adjustment platform and the preset position of the display module to be tested, the data processing apparatus further includes:
For example, referring to fig. 8, the loading platform 20 drives the display module to be tested to move to the image obtaining position B.
For example, referring to fig. 8, the image obtaining device 40 obtains the actual position of the display module to be measured on the adjustment platform, and sends the actual position to the data processing device. Specifically, the image acquisition device 40 may be an industrial camera.
According to the technical scheme, the actual position of the display module to be tested on the adjusting platform is obtained through the image obtaining device and is sent to the data processing device, the data processing device determines the deviation of the display module to be tested between the actual position and the preset position of the adjusting platform, the controller controls the movement module to adjust the actual position of the display module to be tested to coincide with the preset position based on the deviation of the display module to be tested between the actual position and the preset position of the adjusting platform, it can be guaranteed that no deviation exists between the position of the display module on the loading platform and the grabbing position of the transfer mechanism, it is guaranteed that the transfer mechanism can grab safely and place the display module to be tested on the testing station, the damage rate of the display module to be tested in the process that the transfer mechanism transfers the display module to the testing station from the loading platform is reduced.
In the technical scheme, the transfer mechanism places the display module to be tested at the test station, and the number of the test stations is more than one in order to improve the test speed. How to assign the display module to be tested to the corresponding test station is described in detail below.
Fig. 3 is a schematic flow chart illustrating a transmission method of a display module according to another embodiment of the present invention. Optionally, referring to fig. 3, the step 150 of placing the display module to be tested at the test station by the transferring mechanism includes:
For example, referring to fig. 8, the first test station 30A and the second test station 30B have different priority orders, and the test station with higher priority represents that it will be preferentially assigned to the display module to be tested.
For example, the priority of the first test station 30A is higher than that of the second test station 30B, and then the display module to be tested is placed at the first test station 30A. And if the priority of the second test station 30B is higher than that of the first test station 30A, placing the display module to be tested at the second test station 30B.
According to the technical scheme in the embodiment, the transfer mechanism places the display module to be tested at the test station according to the priority sequence of the test station, so that the production efficiency can be effectively improved.
The following describes the priority order acquisition process in detail. Fig. 4 is a schematic flow chart illustrating a transmission method of a display module according to another embodiment of the present invention. Optionally, referring to fig. 4, the step 1501 the controller obtaining a priority order for the test workstations includes:
When the test station has no display module to be tested, the communication module at the test station sends a feeding request to the controller, the controller can respectively time the time of the feeding request sent by the communication module at the test station, and when the display module to be tested is placed on the test station, the communication module at the test station stops sending the feeding request. And the controller acquires the priority sequence of the test stations according to the time of the feeding request sent by the communication module at the test stations. The longer the time a loading request is sent by a communication module at a test station, the higher its priority. The method does not delay production due to breakdown of a certain test station, can efficiently and reasonably distribute the display modules to be tested, does not cause the previous test station or the condition that an operator is always in a high load state due to the principle of being close to the operator, gives consideration to the operation proficiency of the operator, reasonably and properly increases the productivity of the skilled operator, and can effectively improve the production efficiency.
The specific process of the data processing apparatus acquiring the preset position of the display module to be tested on the adjustment platform is described in detail below, which includes the acquisition process of the preset position and the verification process of the preset position. The process of acquiring the preset position may also be referred to as a reverse dotting process, and the process of verifying the preset position may also be referred to as a forward verification process.
Fig. 5 is a schematic flow chart illustrating a transmission method of a display module according to another embodiment of the present invention. Optionally, referring to fig. 5, the step 120 of determining, by the data processing device, a deviation between the actual position of the adjustment platform and the preset position of the display module to be tested further includes:
It should be noted that, referring to fig. 8, a test station may include m test stations, where m is greater than or equal to 1. Fig. 8 shows only 2 test stations, a first test station 30A and a second test station 30B, by way of example. And each testing station is provided with a corresponding sample display module and a sample preset position of the sample display module. The negative pressure is formed between the transferring mechanism and the sample display module to fix the sample display module on the transferring mechanism, the transferring mechanism places the sample display module at the sample preset position of the adjusting platform on the loading platform, and the process can be carried out under the supervision of an operator. The size and the shape of the sample display module are completely the same as those of the display module to be detected.
And 1204, the feeding platform sequentially drives the sample display module on each test station in the m test stations to move to the image acquisition position.
For example, referring to fig. 8, the loading platform 20 sequentially drives the sample display module on each of the m testing stations to move to the image capturing position B.
And step 1205, the image acquisition device sequentially acquires the sample preset position of the sample display module on each test station in the m test stations on the adjustment platform.
And step 1206, the data processing device sequentially stores the sample preset position on each test station in the m test stations as the preset position of the display module to be tested on the adjusting platform.
For example, the sample preset position may be represented by the position coordinates of the sample display module on the adjustment platform, such as m _ x, m _ y, m _ z, where m represents the number of the test station. It should be noted that, when the image obtaining device obtains the sample preset position of the sample display module on the adjustment platform, all the sample preset positions of the m test stations need to be obtained, and the above process is referred to as a sample preset position obtaining process, and may also be referred to as a reverse dotting process.
According to the technical scheme in the embodiment, the acquisition of the sample preset position by the image acquisition device is completed, and the sample preset position is stored as the preset position of the display module to be detected on the adjusting platform by the data processing device.
In order to increase the accuracy of the data processing device for acquiring the preset position of the display module to be tested on the adjustment platform, the embodiment provides the following technical scheme:
fig. 6 is a schematic flow chart illustrating a transmission method of a display module according to another embodiment of the present invention. Optionally, referring to fig. 6, the step 1206 of storing the preset sample position as the preset position of the display module to be tested on the adjusting platform by the data processing apparatus includes:
It should be noted that, as opposed to the reverse dotting process, steps 12062-12068 may be referred to as a forward verification process, that is, verifying whether the preset position of the sample obtained in the above technical solution is accurate. Before the forward verification process, the sample display module is removed from the sample preset position of the adjusting platform by using the transfer mechanism, so that the adjusting platform for placing the display module to be tested on the feeding platform in the verification process is convenient. It should be noted that, the forward verification process needs to be performed on all the preset positions of the adjustment platform of the display modules to be tested corresponding to the m test stations.
Illustratively, referring to fig. 8, the loading platform 20 is moved to the loading position a.
For example, referring to fig. 8, the transferring mechanism 10 places the display module to be tested on the adjusting platform 21 of the loading platform 20.
For example, referring to fig. 8, the loading platform 20 drives the display module to be tested to move to the image obtaining position B. The image acquiring device 40 acquires the actual position of the display module to be measured on the adjusting platform and sends the actual position to the data processing device. And the data processing device determines the deviation of the display module to be detected between the actual position of the adjusting platform and the sample preset position. The actual position coordinates of the display module to be measured on the adjusting platform can be represented by Pdt _ x, Pdt _ y and Pdt _ z. And the data processing device determines and adjusts the deviation of the display module to be measured between the actual position coordinates Pdt _ x, Pdt _ y and Pdt _ z of the adjusting platform and the sample preset position coordinates m _ x, m _ y and m _ z according to the signal interacted by the controller.
And the motion module adjusts the actual position coordinates Pdt _ x, Pdt _ y and Pdt _ z of the display module to be detected to the sample preset position coordinates m _ x, m _ y and m _ z based on the position adjustment control signal.
After the adjustment is in place, the transfer mechanism places the display module to be tested on a test station for testing. For example, referring to fig. 8, the loading platform 20 drives the display module to be tested to move to the loading waiting station C. The moving and carrying mechanism 10 places the display module to be tested at the testing station for testing.
It should be noted that, within the preset number of testing times, according to the testing success rate at each testing station, the preset position coordinates m _ x, m _ y, and m _ z of the sample may be corrected appropriately, so as to obtain the preset position with high accuracy. The specific test comprises the following steps: electrical property test, Mura test, optical property test, appearance test, aging test and the like. The electrical performance test comprises a lighting test of the display module to be tested.
It should be noted that, after the data processing apparatus stores the sample preset position as the preset position of the display module to be tested on the adjustment platform, steps 12062-12068 are actually verification processes for the sample preset position to be equal to the preset position of the display module to be tested on the adjustment platform. If the transfer mechanism 10 places the display module to be tested on the adjusting platform 21 on the feeding platform 20, and the data processing device determines the deviation of the display module to be tested between the actual position of the adjusting platform and the sample preset position, the controller controls the motion module to adjust the actual position of the display module to be tested to coincide with the sample preset position based on the deviation of the display module to be tested between the actual position of the adjusting platform and the sample preset position, the transfer mechanism places the display module to be tested on the testing station for testing, the transfer mechanism tests successfully on the testing station, the sample preset position is proved to be equal to the preset position of the display module to be tested on the adjusting platform, and the data processing device can store the sample preset position as the preset position of the display module to be tested on the adjusting platform.
It should be noted that, when the shape of the display module to be tested does not conform to the preset shape or the actual position on the adjustment platform exceeds the visual field range of the camera, the data processing device may select one or more ways of retrying, manually removing the display module to be tested, and automatically removing the display module to be tested according to the interaction signals of the data processing device and the controller, so that the whole device does not stop operating or crash.
Based on the same inventive concept, the embodiment of the invention also provides a transmission system of the display module. Fig. 7 is a schematic structural diagram of a transmission system of a display module according to an embodiment of the present invention.
