Implementation

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 An SMT patch storage rack in this embodiment includes a base 1, a placement rack 2 is arranged on the top of the base 1, a mounting plate 3 is movably installed inside the placement rack 2, a picking mechanism 4 is arranged between the mounting plate 3 and the inside of the placement rack 2, and a positioning mechanism 5 is arranged on the mounting plate 3.

[0023] like Figure 2 As shown, the taking mechanism 4 includes a motor 401 , a sprocket 1 402 is fixedly installed on the output shaft of the motor 401 , a chain 403 is installed on the outer surface of the sprocket 1 402 for transmission, and a sprocket 2 404 is installed on the inner surface of the chain 403 for transmission.

[0024] Through the transmission cooperation among sprocket 1 402, chain 403 and sprocket 2 404, when the motor 401 is started, the chain 403 is driven to run, so as to adjust the position of the mounting plate 3. After the mounting plate 3 at a high position is adjusted to a suitable height, the SMT patch can be taken. Pulleys are fixedly installed on the opposite sides of the eight mounting plates 3. Slide rails matching the pulleys are provided on the left and right inner walls of the placement rack 2. Under the action of the pulleys and the slide rails, the stability of the mounting plate 3 during movement is improved. There are eight mounting plates 3. Three groups of positioning mechanisms 5 are provided on each mounting plate 3, and every two positioning mechanisms 5 form a group. By arranging multiple mounting plates 3 and multiple positioning mechanisms 5, it is convenient to store multiple SMT patches. A protective pad is provided on the opposite side of each two positioning plates 505. Under the action of the protective pad, both sides of the SMT patch can be made to contact with the protective pad, thereby protecting the SMT patch.

[0025] like Figure 2 and Figure 3 As shown, the positioning mechanism 5 includes a receiving groove 501 opened on the top of the mounting plate 3, a connecting rod 502 is fixedly installed inside the receiving groove 501, a guide block 503 is slidably installed on the outer surface of the connecting rod 502, a spring 504 sleeved on the outer surface of the connecting rod 502 is fixedly installed between one side of the guide block 503 and the inner wall of the receiving groove 501, and a positioning plate 505 is fixedly installed on the top of the guide block 503.

[0026] When the SMT patch is placed between every two positioning mechanisms 5, the two positioning pieces 505 can slide on the outer surface of the connecting rod 502 through the guide block 503 at the bottom under the contraction and expansion of the spring 504, thereby fixing the SMT patch.

[0027] like Figure 1 As shown, movable wheels are provided at the four corners of the bottom of the base 1. By providing the movable wheels, it is convenient to move the device to the position where it is needed. A movable door is movably installed on the front side wall of the base 1 to facilitate the maintenance and care of the inside of the device. A power supply is provided inside the base 1, and a switch button is provided on the front side wall of the placement rack 2. The power supply is the power source of the device, and the motor 401 is turned on and off by the switch button.

[0028] like Figure 1 and Figure 2 As shown, a ventilation channel 6 is arranged on the top of the placement rack 2, a dustproof net 601 is arranged on the top of the ventilation channel 6, and an exhaust fan 602 is arranged inside the ventilation channel 6. By arranging the ventilation channel 6 and the exhaust fan 602, the internal moisture can be effectively discharged from the interior of the equipment. At the same time, a dustproof net 601 is arranged on the top of the ventilation channel 6 to prevent dust and other impurities from entering the interior of the equipment.

[0029] When implementing, follow these steps:

[0030] 1) First, move the device to the position where it needs to be used by the moving wheels. When taking the SMT patches stored at a high place, first open the movable door and start the motor 401 by pressing the switch button;

[0031] 2) Then the motor 401 drives the sprocket 1 402 to rotate, the sprocket 1 402 drives the chain 403 to rotate, and the chain 403 drives the sprocket 2 404 to rotate. At this time, the chain 403 is in a conveying state, and the mounting plate 3 located at a high position will gradually move downward. During the process of the mounting plate 3 descending, the mounting plate 3 slides stably inside the slide rail through the pulley until it descends to a suitable height. Then, the switch button is pressed to turn off the motor 401, and the chain 403 stops conveying;

[0032] 3) Finally, the SMT patch clamped between the two positioning pieces 505 is pulled out through the contraction and expansion of the spring 504, and then the movable door is closed.

[0033] In summary, the SMT patch storage rack, by providing the taking mechanism 4, can move the mounting plate 3 located at a high position downward to facilitate taking of the SMT patches located on the mounting plate 3 located at a high position.

[0034] Furthermore, by providing the positioning mechanism 5 , the SMT patch can be clamped between the two positioning pieces 505 , so that the SMT patch is stably fixed on the mounting plate 3 , which facilitates the storage of the SMT patch.
