Please refer to [link / reference]. Figures 1-2 This paper provides a detailed description of a tray loading device for a selective wave soldering machine.

[0027] A pallet feeding device for a selective wave soldering machine includes a housing 100, a feeding mechanism 200, a picking area 300, a lower feeding mechanism 400, and an upper feeding mechanism 500.

[0028] The feeding mechanism 200 includes a fixed frame 201 fixed to the outside of the housing 100. The top of the fixed frame 201 is provided with a feeding conveyor belt 202 for conveying trays 203. At least two trays 203 are provided, and material 204 is placed on the top of each tray 203.

[0029] The material taking area 300 is located on one side of the housing 100 and at the end of the material feeding conveyor belt 202.

[0030] The lower feeding mechanism 400 is raised and lowered inside the material picking area 300. The lower feeding mechanism 400 includes a lifting platform 401 that is raised and lowered by a first lifting cylinder 403. The top of the lifting platform 401 is provided with a lower feeding conveyor belt 402 for aligning with the material feeding conveyor belt 202 and receiving the pallet 203.

[0031] The upper feeding mechanism 500 is raised and lowered inside the material picking area 300 and is always located above the lifting platform 401. The upper feeding mechanism 500 includes two mounting plates 501 that are raised and lowered by the second lifting cylinder 503. An upper feeding conveyor belt 502 for aligning the material feeding conveyor belt 202 and receiving the pallet 203 is provided between the two mounting plates 501.

[0032] Furthermore, the lower feeding conveyor belt 402 is moved forward and backward by a first displacement component. The first displacement component includes a horizontal lead screw 404 rotatably mounted on the top of the lifting platform 401. A transmission block 405 is screwed onto the body of the lead screw 404. The lower feeding conveyor belt 402 is positioned above the transmission block 405. A forward and reverse servo motor 406 is fixedly mounted on the top of the lifting platform 401. The output shaft of the forward and reverse servo motor 406 is connected to the end of the lead screw 404 via a coupling. A limiting slide rod 407 parallel to the lead screw 404 is fixedly mounted on the top of the lifting platform 401. The body of the limiting slide rod 407 slides through the side wall of the transmission block 405, which can activate the forward and reverse servo motor 406 to drive the lead screw 404 to rotate, causing the lower feeding conveyor belt 402 to move forward. This causes the tray 203 on the lower feeding conveyor belt 402 to protrude from the material picking area 300 for easy retrieval.

[0033] Furthermore, the upper feeding conveyor belt 502 is moved forward and backward by a second displacement component. The second displacement component includes a first electric telescopic rod 504 and a second electric telescopic rod 505 fixed to the side wall of the rear mounting plate 501. The first electric telescopic rod 504 and the second electric telescopic rod 505 are connected in series in the control circuit. The upper feeding conveyor belt 502 is located on the output ends of the first electric telescopic rod 504 and the second electric telescopic rod 505, and the output ends of the first electric telescopic rod 504 and the second electric telescopic rod 505 are fixed to the side wall of the front mounting plate 501. The first electric telescopic rod 504 and the second electric telescopic rod 505 can be activated to push the upper feeding conveyor belt 502 and the front mounting plate 501 forward, thereby making the tray 203 on the upper feeding conveyor belt 502 protrude from the material picking area 300 for easy retrieval.

[0034] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
