[0040] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] like Figures 1 to 3 As shown, this embodiment provides a tray temporary storage device for temporarily storing and releasing trays on the assembly line to adapt to the transportation speed of the assembly line and the assembly speed of the assembly station. The tray contains materials for assembly, and the materials are transported to the assembly station for assembly with other materials.

[0042] The tray temporary storage device includes a temporary storage frame 100, a lifting assembly 200 and a supporting assembly 300, wherein the temporary storage frame 100 has a temporary storage cavity 101 and a lower opening 102 connected to the temporary storage cavity 101; the lifting assembly 200 includes a lifting drive 210 and a lifting member 220 arranged at the output end of the lifting drive 210, and the lifting member 220 moves between a lifting position and a lowering position along a first direction; the supporting assembly 300 includes a supporting drive 310, a supporting drive 320 and a supporting member 330, the supporting drive 310 is arranged on a bracket of the assembly line, the supporting drive 320 is arranged at the output end of the supporting drive 310, and can move between a supporting position and a falling position along a first direction, and the supporting member 330 is arranged at the output end of the supporting drive 320, and can move between a supporting position and a retracted position along a second direction.

[0043] In this embodiment, the first direction is the up-down direction, and the second direction is the left-right direction, wherein the first direction and the second direction are perpendicular.

[0044] The above arrangement enables the material trays on the assembly line to be temporarily stored when the material tray transfer speed is higher than the assembly speed of the assembly station to avoid material backlog; when the material tray transfer speed of the assembly line is lower than the assembly speed of the assembly station, the temporarily stored material trays can be released to avoid material shortages at the assembly station and ensure assembly efficiency. The material trays on the assembly line can be lifted up by the lifting assembly 200, and the support drive member 310 and the support drive member 320 in the support assembly 300 act simultaneously, so that the support member 330 can move between the supporting position and the retracted position. The support member 330 at the supporting position can support the material tray, and the support member 330 at the retracted position can avoid the material tray. Under the action of the support drive member 310, the support member 330 moves above and below the lowest material tray. The arrangement of the support driving member 310 enables the supporting member 330 to be driven to move between the lower side of the lowest material tray and the upper side of the lowest material tray while the lifting member 220 remains in position. That is, in the bottom-up direction, the supporting member 330 can be transferred below the first material tray and between the first material tray and the second material tray, thereby preventing the lifting driving member 210 from carrying too many material trays during the lifting process, reducing the power requirements for the lifting driving member 210, reducing costs, and increasing the service life of the lifting driving member 210.

[0045] During use, when all the trays in the temporary storage chamber 101 need to be pushed up or put down, the lifting driving member 210 and the supporting driving member 310 may be actuated simultaneously, or the supporting driving member 310 may be actuated alone.

[0046] In some embodiments, the supporting member 330 includes a fixing plate 331 and a supporting plate 332, the fixing plate 331 and the supporting plate 332 are arranged at an angle, the fixing plate 331 is arranged at the output end of the supporting driving member 320, and the supporting plate 332 is used to support the bottom of the material tray. The fixing plate 331 and the supporting plate 332 are perpendicular.

[0047] The supporting driving member 320 includes a guide cylinder, and the supporting member 330 is arranged at the output end of the guide cylinder. The guide cylinder has its own guide rail, which helps to simplify the structure of the supporting member 330 and improve the assembly efficiency of the material tray temporary storage device.

[0048] The supporting assembly 300 includes a pad 340, which is sandwiched between the fixed plate 331 and the output end of the supporting driving member 320. The pad 340 can be made of rubber or iron. The supporting driving member 320 includes a guide cylinder, a transfer seat 321 is arranged on the piston rod of the guide cylinder, and the transfer seat 321 is connected to the fixed plate 331. The transfer seat 321 is provided with a fixing screw hole, and the fixing plate 331 is provided with a fixing light hole 3311. The fixing screw passes through the fixing light hole 3311 and is threadedly matched with the fixing screw hole of the transfer seat 321.

[0049] There are four fixing screws, four fixing light holes 3311 and four fixing screw holes, and they are arranged corresponding to the fixing screws. Two of the four fixing screws form a group, and the two fixing screws in each group are arranged at intervals along the first direction, and the two groups of fixing screws are arranged at intervals along the third direction. The third direction is the front-to-back direction, the third direction is perpendicular to the first direction, and the third direction is perpendicular to the second direction.

[0050] The supporting assembly 300 includes a backing plate 340, and the backing plate 340 is provided with two notches 341, the opening direction of the notches 341 is downward, and the two notches 341 are arranged at intervals along the front-back direction, and the two fixing screws in each group are located in the same notch 341. This arrangement allows the four fixing screws to pass through the corresponding fixing light holes 3311 and into the corresponding fixing screw holes respectively. When the backing plate 340 is not fully tightened, the backing plate 340 is inserted from top to bottom into the gap between the fixing plate 331 and the intermediate transfer seat 321, and then the fixing screws are tightened, thereby improving the installation efficiency of the backing plate 340.

[0051] In some embodiments, two supporting assemblies 300 are provided, the two supporting assemblies 300 are arranged at an interval, and the two supporting members 330 in the two supporting assemblies 300 are respectively used to support the two sides of the material tray, and the two supporting assemblies 300 are separated on both sides of the assembly line.

[0052] During use, when all the trays need to be pushed up or put down, the two support driving members 310 in the two supporting assemblies 300 are simultaneously actuated, thereby further reducing the power requirement for the support driving members 310 and reducing the cost.

[0053] It should be noted that the two supporting members 330 are arranged opposite to each other. The two supporting members 330 can move inward relative to each other and can both move to the supporting position to complete the support of the material tray. The two supporting members 330 can move outward relative to each other and can both move to the retracted position to be located on both sides of the material tray.

[0054] In some embodiments, the temporary storage frame 100 includes four angle irons 110, which are arranged in a matrix and surround the temporary storage cavity 101. The projection of the material tray in the first direction is a quadrilateral, and the four angle irons 110 are respectively located at the four corners of the material tray to limit the four corners of the material tray.

[0055] The assembly line includes a bracket and two conveyor belts rotatably arranged on the bracket. In order to facilitate fixing the angle iron 110 on the bracket of the assembly line, the tray temporary storage device includes four fixing seats 120, and each angle iron 110 is fixed to a corresponding fixing seat 120, and the fixing seat 120 is used to connect with the bracket of the assembly line. The fixing seat 120 is installed on the bracket, so that the width of the temporary storage chamber 101 can be adapted to the bracket, and trays of different widths can be temporarily stored. The width of the temporary storage chamber 101 is the size of the temporary storage chamber 101 in the second direction. At the same time, the length of the temporary storage chamber 101 is also easy to adjust. Among them, the length of the temporary storage chamber 101 is the size of the temporary storage chamber 101 in the third direction.

[0056] In order to improve the structural stability of the temporary storage frame 100, the temporary storage frame 100 also includes four connecting members 130, each connecting member 130 is connected between any two angle irons 110. The connecting member 130 is provided with a connecting hole 131, and the angle iron 110 is provided with a fixing hole. The connecting screw passes through the connecting hole 131 and is threadedly engaged with the fixing hole. Among them, the connecting member 130 is in the shape of a long strip, and the connecting hole 131 is in the shape of a long strip. The extending direction of the connecting hole 131 is the same as the extending direction of the connecting member 130, so as to adapt to production lines of different widths and can adapt to trays of different sizes.

[0057] Since the material tray needs to enter the temporary storage chamber 101 from the lower opening 102 below the temporary storage chamber 101, in order to improve the smoothness of the material tray entering the temporary storage chamber 101, in some embodiments, the length of the lower opening 102 gradually increases from top to bottom, that is, the lower opening 102 is a flared structure from top to bottom in the front-to-back direction. In some embodiments, the width of the lower opening 102 gradually increases from top to bottom, that is, the lower opening 102 is a flared structure from top to bottom in the left-to-right direction. In some embodiments, the length of the lower opening 102 gradually increases from top to bottom, and the width of the lower opening 102 gradually increases from top to bottom. The length of the lower opening 102 is the size of the lower opening 102 in the third direction, and the width of the lower opening 102 is the size of the lower opening 102 in the second direction.

[0058] When the tray needs to be temporarily stored, the assembly line can stop running so that the tray is located directly below the lower opening 102. To ensure that the tray is accurately stopped, in some embodiments, the tray temporary storage device further includes a stop assembly 400, which includes a stop driving member 410 and a stop member 420 provided at the output end of the stop driving member 410. The stop member 420 can move between a stop position and an avoidance position along a first direction. The stop member 420 at the stop position is higher than the assembly line, and can stop the tray on the assembly line from continuing to move forward and stop directly below the lower opening 102. The stop member 420 at the avoidance position is lower than the assembly line, and can avoid the path of the tray so that the tray can continue to move forward.

[0059] In some embodiments, the lifting assembly 200 further includes a lifting seat 230, and the lifting member 220 is slidably disposed on the lifting seat 230. The above arrangement is conducive to improving the smoothness of the movement of the lifting member 220. The lifting drive member 210 is disposed on the lifting seat 230, and during assembly, it is only necessary to relatively fix the lifting seat 230 and the support of the assembly line to improve the convenience of fixing the lifting drive member 210.

When the first detection member 260 detects that there is a material tray on the lifting member 220, a trigger signal is sent to the controller, and the controller controls the lifting drive member 210 to rise or fall. When the material tray needs to be temporarily stored, the lifting member 220 is located in the falling position. When the first detection member 260 detects the material tray, the controller controls the lifting drive member 210 to drive the lifting member 220 to move to the lifting position. When the material tray needs to be released, the lifting member 220 moves to the lifting position. When the first detection member 260 detects the material tray, the controller controls the lifting driving member 210 to drive the lifting member 220 to move to the lowering position.

[0066] In some embodiments, the tray temporary storage device also includes a second detection member 140, which is arranged on the angle iron 110 and is used to detect the tray in the temporary storage chamber 101. Among them, the second detection member 140 is arranged at the upper end of the angle iron 110, and is used to detect the uppermost tray when the temporary storage chamber 101 is full of trays.
