DETAILED DESCRIPTION

[0027] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0028] With the widespread application of electronic devices, the performance research and development of various components or structural parts in electronic devices or the efficiency of production line assembly need to be improved. Among them, electronic devices can include desktop computers, laptops, tablets or mobile phone terminals. Taking the electronic device as an example, it includes a system end and a display end. The system end can be understood as the side with the keyboard, and the display end is the side with the display screen. The shell on the display end is generally called the B shell. The B shell generally needs to be glued on the back in the production line. One of the existing ways of gluing the back is manual operation, which is inefficient and the B shell is easy to deform; the other is to use an automated conveying structure, and the existing automated conveying structure has problems of one kind or another. Either the movement of the fixture is irregular and requires manual correction; or the product has no positioning function and will move during the conveying process, which will cause damage to the product; or the fixture can only work within a limited length and cannot circulate with the moving plate.

[0029] In order to alleviate the above-mentioned problems, the embodiment of the present disclosure provides a vacuum adsorption fixture, which does not require an external vacuum system, and adopts an independent small vacuum adsorption system installed on a circulating carrier, which greatly simplifies the vacuum system. It can not only realize reciprocating cyclic movement within a longer length, but also ensure that the target part will not be deformed during movement.

[0030] refer to Figure 1-Figure 4 The embodiment of the present disclosure provides a vacuum adsorption fixture 10, including: a carrier platform 11, the carrier platform 11 provides a support plane for carrying a target part 20 and related structural parts, and the carrier platform 11 can perform reciprocating cyclic movements within a preset path. It should be noted that the preset path is set according to the actual needs of the production line. The carrier platform 11 can carry the target part 20 and related structural parts and perform unobstructed reciprocating cyclic movements along the preset path. In this way, the target part 20 will not be damaged during the movement of the carrier platform 11, and this part of the production line can realize the automated adhesive pasting action in an orderly manner without manual participation, thereby further improving the automation efficiency.

[0031] Specifically, the vacuum adsorption fixture 10 also includes a suction cup 12 and a vacuum adsorption system 13, wherein the suction cup 12 is arranged on the loading surface of the carrier platform 11, and can adsorb and position the target part 20, so that during the movement of the carrier platform 11, it is ensured that the target part 20 will not move out of position, thereby ensuring that the target part 20 will not be damaged. In addition, the vacuum adsorption system 13 includes a micro vacuum pump 131, a power supply battery pack 132 for providing power to the micro vacuum pump 131, a wireless network receiving module 133 and a system control module 134. The micro vacuum pump 131 is used to generate a vacuum and stabilize the target part 20 through the vacuum suction hole 1211. It should be noted that the vacuum suction hole 1211 is formed on the suction cup 12. Exemplarily, the vacuum suction hole 1211 is formed along the thickness direction of the suction cup 12 and is aligned with the surface area of ​​the B shell. The system control module 134 is electrically connected to the micro vacuum pump 131 and the power supply battery pack 132 respectively, and the wireless network receiving module is used to receive external control signals. In this way, the vacuum adsorption system 13 can be automatically started and shut down as a whole through automatic control signals, which is convenient for automatic adsorption and positioning of the target part 20.

[0032] Furthermore, the vacuum adsorption system 13 is installed as a whole on the side of the carrier platform 11 away from the loading surface, and the structural parts included in the vacuum adsorption system 13 do not extend out of the outer contour surface of the carrier platform 11. In this way, during the reciprocating movement of the carrier platform 11 along the preset path, the vacuum adsorption system 13 as a whole will not collide with parts outside the preset path, thereby realizing the reciprocating movement of the vacuum adsorption system 13 following the carrier platform 11.

[0033] Specifically, the vacuum adsorption fixture 10 further includes a solenoid valve 14, which is a standard switch component and is installed on the side of the carrier platform 11 away from the object loading surface. The solenoid valve 14 is used to control the opening and closing of the micro vacuum pump 131. Exemplarily, the micro vacuum pump 131, the charging socket 15 and the power supply battery pack 132 are located on the first side of the carrier platform 11, the wireless network receiving module 133 and the system control module 134 are located on the second side of the carrier platform 11, the first side and the second side are arranged oppositely, and the solenoid valve 14 is located in the middle of the carrier platform 11, that is, the solenoid valve 14 is located between the first side and the second side.

[0034] In order to realize the automatic identification function of the vacuum adsorption fixture 10, the embodiment of the present disclosure also includes a first sensor and a second sensor, wherein the first sensor is respectively connected to the system control module 134 and the vacuum channel of the suction cup 12, so that the first sensor can sense whether the vacuum suction hole 1211 of the suction cup 12 is in a vacuum state, and then the system control module 134 can receive the state information of whether the vacuum suction hole 1211 is in a vacuum state. If the result is negative, the system control module 134 will send out the information that the micro vacuum pump 131 has a fault, so that the maintenance personnel can maintain the equipment. The second sensor is respectively connected to the system control module 134 and the power supply battery pack 132, so that the battery capacity of the power supply battery pack 132 can be identified by the second sensor. When the battery capacity of the power supply battery pack 132 is low, the system control module 134 will receive the information of low battery capacity, and then control the power supply battery pack 132 to move to the charging position for charging, and replace the new carrier platform 11, which is provided with an integral vacuum adsorption system 13.

[0035] Considering the integrated structural performance of the carrier platform 11 and the vacuum adsorption system 13, when the power of the power supply battery pack 132 is exhausted, the entire carrier platform 11 needs to be moved to the charging position. In order to facilitate the charging of the power supply battery pack 132, the vacuum adsorption fixture 10 also includes a charging socket 15, which is located between the micro vacuum pump 131 and the power supply battery pack 132. The charging socket 15 has a guide column 151, and the guide column 151 extends toward the side away from the power supply battery pack 132 and the micro vacuum pump 131. The design of the guide column 151 can facilitate the alignment of the charging socket 15 with the socket of the charging position to improve efficiency.

[0036] Considering the real-time monitoring of the vacuum state of the vacuum adsorption system 13, the vacuum adsorption fixture 10 also includes a vacuum gauge 16 and a vacuum pipeline. The vacuum pipeline is connected between the micro vacuum pump 131 and the vacuum suction hole 1211 of the suction cup 12. The vacuum gauge 16 is respectively connected to the vacuum pipeline and the system control module 134 for feedback of the real-time negative pressure of the vacuum adsorption system 13.

[0037] Considering that the inspectors can see in real time whether the vacuum adsorption fixture 10 is in a normal working state, the vacuum adsorption fixture 10 also includes an indicator light 17, which is connected to the system control module 134 by signal, and is used to indicate the working state of the vacuum adsorption system 13. Exemplarily, the indicator light 17 can flash red and green, the red light can be used to warn of a fault state, and the green light can be used to display a normal working state.

[0038] Considering the overall integration and applicability of the suction cup 12, the suction cup 12 can be assembled. For example, the suction cup 12 includes an upper plate 121, a lower plate 122 and an air joint 123. The air joint 123 is connected to the micro vacuum pump 131 through an air pipe. The vacuum suction hole 1211 is connected to the air joint 123. The upper plate 121 covers and is installed on the through hole of the lower plate 122. The through hole is connected to the vacuum suction hole 1211. Among them, the upper plate 121 has a receiving groove for receiving the B shell, and the vacuum suction hole 1211 is directly formed in the receiving groove of the upper plate 121.

[0039] When the vacuum adsorption fixture 10 of the embodiment of the present disclosure is used, the micro vacuum pump 131 generates vacuum by powering the battery pack 132, and the vacuum stabilizes the thin B part in the vacuum fixture through the suction cup 12. The solenoid valve 14 controls the system to break the vacuum. The system control module 134 determines the vacuum condition, battery capacity, etc. through sensors. The wireless network transceiver communicates information with the external control system. The vacuum meter 16 feedbacks the system negative pressure. The indicator light 17 indicates the vacuum system status and manual stop. The charging socket 15 facilitates external battery charging.

[0040] The disclosed embodiment also provides a fixture battery automatic replacement device, including the above-mentioned vacuum adsorption fixture 10, and also includes a lifting mechanism 50, a discharge bin 30 and a pick-up bin 40 located at both ends of a preset path, the lifting mechanism 50 is used to transfer the vacuum adsorption fixture 10 to the discharge bin 30 or the pick-up bin 40, and the discharge bin 30 and the pick-up bin 40 are both provided with an automatic charging device. Specifically, it also includes an upper and lower conveyor line, and the lifting mechanism 50 can be understood as a discharge elevator, wherein the discharge bin 30 and the pick-up bin 40 mainly include telescopic guide rails, a push-out cylinder, a detection device and a charging mechanism. When working: the pick-up bin 40 places the carrier platform 11 (with a vacuum adsorption system 13) for standby. When the battery capacity of the power supply battery pack 132 in the circulating conveyor line is insufficient, it is placed from the circulating conveyor line to the discharge bin 30 by the lifting mechanism 50, and at the same time, the lifting mechanism 50 replenishes the carrier platform 11 with sufficient batteries to the circulating conveyor line. After that, the charging mechanism of the discharge bin 30 works to charge it.

[0041] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps recorded in this disclosure can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of this disclosure can be achieved, and this document is not limited here.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.
