[0047] Specifically, the production cycle of the automatic labeling, number writing, upgrading, and verification equipment is as follows:

[0048] 1. The mobile terminal runs to the labeling station for positioning. After positioning is completed, the label is attached, and finally it is sent to the discharging position by the belt line, with a cycle of about 8 seconds.

[0049] 2. In the test fixture of the automatic number writing and first automatic upgrading equipment, assuming that 4 sets of fixtures have mobile terminals placed on them and there is a mobile terminal about to complete the test, starting from the 5th piece of material to calculate the cycle, the longest handling cycle is about 8 seconds.

[0050] 3. There are a total of 12 sets of test fixtures in the automatic number writing and first automatic upgrading equipment. The number writing and testing time is 35 seconds, that is, the test cycle is 35 / 12 = 3 seconds. It takes about 1 second for the fixture to complete the positioning of the mobile phone, so the test cycle can be calculated as 4 seconds.

[0051] 4. In the second automatic upgrading equipment, assuming that 47 sets of fixtures have mobile terminals placed on them and there is a mobile terminal about to complete the test, starting from the 48th piece of material to calculate the cycle, the longest handling cycle is about 8.0 seconds.

[0052] 5. There are a total of 48 sets of test fixtures in the second automatic upgrading equipment. When the longest test duration of the second automatic upgrading equipment ≤ 420 seconds, that is, when the second upgrade test is calculated based on the longest 420 seconds, the cycle is 420 / 48 = 8.75 seconds. It takes about 1 second for the fixture to complete the positioning of the mobile terminal, and the test cycle can be calculated as 9.75 seconds.

[0053] 6. Check the test assumptions. Assume that there are mobile phones in 15 sets of jigs, and the existing mobile phones are about to complete the test. Calculate the cycle time starting from the 16th piece of material. The longest handling cycle time is about 8.0 seconds.

[0054] 7. There are a total of 24 sets of test jigs in the automatic checking device. When the longest checking test time ≤ 140 seconds, that is, when calculated according to the longest 140 seconds, the cycle time is 140 / 24 = 5.9 seconds. It takes about 1 second for the jig to complete the positioning of the mobile terminal, and the test cycle time can be calculated as 7.0 seconds.

[0055] In summary, we can get:

[0056] 1) The overall line cycle time of the device can be calculated as 9.75 s. In theory, the hourly production capacity UPH = 3600 / 9.75 = 369 pcs / h. If the equipment operating rate is calculated at 90% - 95%, then the actual hourly production capacity UPH = 369*90% - 369*95% = 332 - 350.

[0057] 2) The overall line cycle time of the device is restricted by the upgrade 2 test. If the test time ≤ 320 s (the test cycle time is about 7.7 s), the overall line cycle time can be calculated as 8 s. In theory, the hourly production capacity UPH = 3600 / 8 = 450 pcs / h. If the equipment operating rate is calculated at 90% - 95%, then the actual hourly production capacity UPH = 450*90% - 450*95% = 405 - 427.

[0058] It can be seen from this that the automatic labeling, number writing, upgrade and checking device reduces the production cost and improves the production efficiency and productivity of the device.

[0059] In the above automatic labeling, number writing, upgrade and checking device, the automatic labeling device, the automatic number writing and the first automatic upgrade device, the second automatic upgrade device and the automatic checking device can operate independently or in series. The belt conveyor mechanism is used to convey the mobile terminal between two devices. The servo module, the gripper suction cup feeding component, the test jig and the USB position adjustment mechanism are general devices, applicable to mobile terminals of different models and sizes, with strong adaptability. The USB test head adopts a floating connection structure to achieve fine position adjustment when docking with the mobile terminal, avoiding scratching the mobile terminal. In the automatic number writing and the first automatic upgrade device, the second automatic upgrade device and the automatic checking device, multiple mobile terminals can be upgraded and tested simultaneously, improving the production efficiency. The structure of the present invention is simple, easy to implement, low in cost and convenient for promotion.

[0060] It should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
