In the description of the present invention, "a plurality" means two or more, unless otherwise specifically defined.

[0036] Example 1: As Figures 1 to 3 shown, a management device for mass production of parts includes:

[0037] The tray lifting mechanism 2, the tray lifting mechanism 2 includes a first driving unit, a driving guide rail module 204 and a driven guide rail module 205; the driving guide rail module 204 and the driven guide rail module 205 are arranged in parallel, the first driving unit is connected to the driving guide rail module 204 through a first transmission chain 203, and the driving guide rail module 204 and the driven guide rail module 205 are connected through a reversing device 206 and then move in opposite directions;

[0038] The tray group, there are two sets of the tray group, which are respectively arranged on the driving guide rail module 204 and the driven guide rail module 205, and each set of tray group includes a plurality of trays 207 arranged at vertical intervals;

[0039] The tray synchronous exchange mechanism, the tray synchronous exchange mechanism includes a second driving unit, a bottom tray exchange module 304 and a top tray exchange module 305, the bottom tray exchange module 304 and the top tray exchange module 305 are both perpendicular to the driving guide rail module 204 and the driven guide rail module 205, the second driving unit is connected to the bottom tray exchange module 304, and the bottom tray exchange module 304 is connected to the top tray exchange module 305 through a second transmission chain 306. The bottom tray exchange module 304 is arranged at the bottom end of the tray group on the driving guide rail module 204 and the driven guide rail module 205, and the top tray exchange module 305 is arranged at the top end of the tray group on the driving guide rail module 204 and the driven guide rail module 205.

[0040] When the trays on the top end of the driven guide rail module 205 are filled with parts and the rest of the trays are empty, the first driving unit drives all the trays on the driving guide rail module to move upward. Since the driving guide rail module and the driven guide rail module move in opposite directions after being connected by the reversing device, all the trays on the driven guide rail module move downward. Therefore, while all the trays in the driving guide rail module rise a certain distance, all the trays in the driven guide rail module descend a certain distance. At this time, the first driving unit stops working; start the second driving unit, the second driving unit transmits the rotational motion to the bottom tray exchange module. When the bottom tray exchange module pulls an empty tray at the bottom of the driven guide rail module onto the driving guide rail module, the top tray exchange module pushes an empty tray at the top end of the driving guide rail module onto the top layer of the driven guide rail module, completing the push-pull action of one tray and realizing the cycle of one action.

[0041] Embodiment 2: The difference between this embodiment and the above embodiment is:

[0042] Such as Figure 2As shown in the figure, the active guide rail module is an active double-loop chain guide rail module, including the first main double-loop chain guide rail 208 on one side and the second main double-loop chain guide rail 209 on the other side. A tray 207 is arranged between the first main double-loop chain guide rail 208 and the second main double-loop chain guide rail 209. Through the synchronous lifting of the first main double-loop chain guide rail 208 and the second main double-loop chain guide rail 209, the tray is evenly stressed and lifted steadily. At the same height of the first main double-loop chain guide rail 208 and the second main double-loop chain guide rail 209, a plurality of tray hanging plates 210 are provided. The tray 207 is arranged on the tray hanging plate 210. The setting of the tray hanging plate can prevent the tray from slipping when the parts are full and the load is large, ensure the tray is placed horizontally, so that both sides of the tray are evenly stressed and lifted synchronously.

[0043] The driven guide rail module is a driven double-loop chain guide rail module, including the first driven double-loop chain guide rail 2011 on one side and the second driven double-loop chain guide rail 2012 on the other side. A tray is arranged between the first driven double-loop chain guide rail 2011 and the second driven double-loop chain guide rail 2012. Through the synchronous lifting of the first driven double-loop chain guide rail 2011 and the second driven double-loop chain guide rail 2012, the tray is evenly stressed and lifted steadily. At the same height of the first driven double-loop chain guide rail 2011 and the second driven double-loop chain guide rail 2012, a plurality of tray hanging plates 210 are also provided. The tray 207 is arranged on the tray hanging plate 210. The setting of the tray hanging plate can prevent the tray from slipping when the parts are full and the load is large, ensure the tray is placed horizontally, so that both sides of the tray are evenly stressed and lifted synchronously.

[0044] The first driving unit includes a first motor 201 and a first reducer 202 connected to the first motor 201. The first reducer 202 is respectively connected to two first long shafts 2013 through two first drive chains 203. The first main double-loop chain guide rail 208 is arranged on one of the first long shafts 2013, and the second main double-loop chain guide rail 209 is arranged on the other first long shaft 2013. The driving force is transmitted to the active guide rail module through the first long shaft 2013.

[0045] As Figure 2As shown in the figure, the commutation device includes a first gear 2061 and a second gear 2062 that mesh with each other; the first gear 2061 is arranged on the active guide rail module 204, the second gear 2062 is arranged on the first long shaft 2013, and the first long shaft 2013 is connected to the first drive unit through the first drive chain 203; the driven guide rail module 205 is arranged on the first long shaft 2013; the first drive unit drives the movement of the driven guide rail module through the first long shaft. At the same time, the first drive unit drives the active guide rail module to move up or down through the meshing of the first gear and the second gear. Due to the arrangement of the first gear 2061 and the second gear 2062 that mesh with each other, when the same drive device drives the active guide rail module 204 and the driven guide rail module 205 to move, they move in opposite directions, realizing that while the tray on the driven guide rail module moves downward, the tray on the active guide rail module moves upward.

[0046] As Figure 3 shown in the figure, the bottom tray exchange module 304 includes two bottom chain-type guide rails 307 arranged in parallel, and the top tray exchange module 305 includes two top chain-type guide rails 309 arranged in parallel. The two top chain-type guide rails 309 are respectively arranged at the upper part of the two bottom chain-type guide rails 305. The top chain-type guide rail 309 and the bottom chain-type guide rail 307 are connected through the second drive chain 306, that is, the top chain-type guide rail and the bottom chain-type guide rail move synchronously and in the same direction through the second drive chain 306. Specifically, the second drive unit includes a second motor 301 and a second reducer 302 connected to the second motor 301. The second reducer 302 is connected to the two bottom chain-type guide rails 307 through the second long shaft 303. The two top chain-type guide rails 309 are also connected through another second long shaft 303. The two second long shafts 303 are connected through a set of second drive chains 306.

[0047] This management device further includes a push-pull device. The push-pull device includes a top push-pull claw 310 and a bottom push-pull claw 308. The top push-pull claw 310 is arranged at the bottom end of the top chain-type guide rail 309. Specifically, the top push-pull claw 310 is located on the side close to the active guide rail module; the bottom push-pull claw 308 is arranged at the top end of the bottom chain-type guide rail 307, and the bottom push-pull claw is located on the side close to the driven guide rail module. When the top chain-type guide rail 309 and the bottom chain-type guide rail 307 move synchronously and in the same direction, the top push-pull claw 310 arranged at the bottom end of the top chain-type guide rail 309 and the bottom push-pull claw 308 at the top end of the bottom chain-type guide rail move in opposite directions. In order to facilitate pushing and pulling the tray, the bottom push-pull claw 308 matches the bottom end of the tray. When the tray is lowered to a certain height by the tray lifting mechanism, the push-pull claws on both sides can simultaneously contact the features at the bottom of the tray and push or pull the tray linearly along the tray hanging plates on both sides.

[0048] When the tray 207 at the top inside the driven double-ring chain guide module is filled with components and all the other trays 207 are empty, first, the first motor 201 rotates and drives the first reducer 202. The first reducer 202 then synchronously transmits the rotational motion to the driving double-ring chain guide module through a pair of first drive chains 203. Since the driving double-ring chain guide module and the driven double-ring chain guide module are connected by a reversing device and their moving directions are opposite, when all the trays 207 inside the driving double-ring chain guide module rise a certain distance, all the trays 207 inside the driven double-ring chain guide module descend a certain distance, and the first motor 201 stops working. After that, the second motor 301 rotates and drives the second reducer 302. The second reducer then synchronously transmits the rotational motion to the bottom tray exchange module 304 through the second long shaft 303. Since the bottom tray exchange module 304 and the top tray exchange module 305 are connected by a pair of second drive chains 306, the moving directions of the top push-pull pawl at the bottom end of the top tray exchange module and the bottom push-pull pawl at the top end of the bottom tray exchange module are opposite. Therefore, while the push-pull pawl 308 on the bottom tray exchange module 304 pulls an empty tray from the bottom layer of the driven double-ring chain guide module to the bottom layer of the driving double-ring chain guide module, the top tray exchange module pushes an empty tray from the top layer of the driving double-ring chain guide module to the top layer of the driven double-ring chain guide module 204, thus completing one cycle.

[0049] Embodiment 3: As Figure 4 shown, the tray lifting mechanism and the tray synchronous exchange mechanism are arranged on the frame 1. The frame 1 is an open-frame made of sheet metal parts, which is easy to find the fault location and replace components;

[0050] A stop post 101 is also arranged inside the frame 1. The stop post 101 is located between the driving guide module 204 and the driven guide module 205, which can prevent the slippage of the tray during the movement of the management unit. There are spaces between the stop post 101 and the top end and the bottom end of the frame 1, which is convenient for the exchange of trays at the top and bottom ends of the driving guide module and the driven guide module;

[0051] Four rollers 102 are arranged at the bottom of the frame 1, and braking devices are arranged on all four rollers 102, which can push the overall management unit to move freely or brake at a certain fixed position.

[0052] In order to fix the positions of the components and prevent the components from moving inside the tray, a plurality of grooves for placing components are arranged on the tray 207, and grooves with different shapes can be designed according to different components.
