[0042] In this embodiment, the feeding conveying and lifting structure 2 and the discharging conveying and lifting structure 3 have the same structure, and the working principles of the two are the same, and the application will be illustrated in detail only by the feeding conveying and lifting structure 2 here.

[0043] The feeding conveying and lifting structure 2 comprises a conveying line 21, the lower end of the conveying line 21 is provided with a lifting module 22, and the lifting end of the lifting module 22 is provided with a carrying fork 23.

[0044] Referring to FIGS. 1, 2 and 3, Figure 2 and Figure 3 In the initial state, the lifting module 22 drives the carrying fork 23 to descend to the bottom, that is, the carrying fork 23 is located below the conveying line 21, when feeding is needed, the conveying line 21 carries the tray containing products to the position of the carrying fork 23, the lifting module 22 drives the carrying fork 23 to move upward and lift the stacked tray, so as to carry the tray containing products to the feeding position of the carrying manipulator 4; thereby completing the feeding.

[0045] It should be noted here that the width of the tray is greater than the width of the conveying line 21, so that the edges of the tray are in a vacant state, so that the carrying fork 23 can be lifted, and the width of the carrying fork 23 is greater than the width of the conveying line 21, so that the tray can be carried and lifted; specifically, in this embodiment, the lifting module 22 is a motor lead screw module, which can drive the carrying fork 23 to lift.

[0046] Limiting plates 24 are arranged on both sides of the conveying path of the conveying line 21; referring to FIGS. 1, 2 and 3, Figure 2As shown, the two limiting plates 24 limit the position of the two trays, so that the trays are centrally positioned, thereby facilitating the subsequent carrying and positioning of the carrying manipulator 4 and the tray carrying device 5; in order to improve the central positioning effect, the two side edges of the limiting plate 24 in the vertical direction are in an inclined state, so that the tray is more easily positioned between the two limiting plates 24.

[0047] The conveying line 21 is provided with a guide structure 25 on both sides of the conveying path, and the guide structure 25 comprises an adjusting cylinder 251, and a guide plate 252 is installed at the moving end of the adjusting cylinder 251.

[0048] Referring to Figure 2 and Figure 4 As shown, the two guide structures 25 are located on both sides of the conveying path of the conveying line 21, and in order to adapt to trays of different widths, the two guide plates 252 can be adjusted in position, that is, the distance between the two guide plates 252 is adjusted, and specifically, the two adjusting cylinders 251 drive the guide plates 252 connected thereto to move, thereby adjusting the distance between the guide plates 252, so that they can adapt to trays and products of different widths.

[0049] The carrying manipulator 4 comprises a manipulator 41, a lifting cylinder 42 is installed at the moving end of the manipulator 41, a fixed plate 43 is fixedly installed at the lifting end of the lifting cylinder 42, and a plurality of suction cups 44 are fixedly installed on the fixed plate 43.

[0050] Referring to Figure 5 As shown, the fixed plate 43 is driven to a predetermined position by the manipulator 41, then the suction cups 44 on the fixed plate 43 are driven into contact with the product by the lifting cylinder 42, the product is adsorbed by the suction cups 44, the product adsorbed by the suction cups 44 is moved by the lifting cylinder 42, and the product is carried to a predetermined position by the manipulator 41, thereby achieving feeding; it should be noted that the manipulator 41 is not limited to a manipulator, but can also be an industrial robot, a three-axis driving module, etc. carrying structure, and the specific implementation is not limited here, and can be freely selected according to the actual situation, that is, any device that can realize the carrying function can be used.

[0051] The tray carrying device 5 comprises a two-axis carrying module 51, a mounting plate 52 is fixedly installed at the moving end of the two-axis carrying module 51, and a clamping assembly 53 is installed at both ends of the mounting plate 52.

[0052] Referring to Figure 6As shown, when the product needs to be carried, first, the two-axis carrying module 51 drives the mounting plate 52 to move to the empty tray position, so that the empty tray is located between the two clamping assemblies 53, then the two clamping assemblies 53 move close to each other to clamp the empty tray located therebetween, and then the two-axis carrying module 51 carries the clamped empty tray to the position of the unloading conveying and lifting structure 3.

[0053] The clamping assembly 53 comprises a first clamping cylinder 531 fixedly installed on the mounting plate 52, a connecting plate 532 fixedly installed on the moving end of the first clamping cylinder 531, and a first clamping plate 533 fixedly installed on the connecting plate 532.

[0054] As shown in Figure 6 and Figure 7 When the two clamping assemblies 53 need to clamp the product, first, the first clamping cylinder 531 drives the connecting plate 532 to move towards the tray, thereby driving the first clamping plate 533 and the hook plate 534 to move towards the tray to clamp the tray. Specifically, the hook plate 534 can be used to hold the bottom surface of the tray during clamping to prevent the tray from falling due to the failure of the clamping force of the first clamping plate 533. In order to achieve load support, the side of the hook plate 534 facing the tray can be provided with an inclined surface (not marked in the figure), so as to facilitate insertion between the top tray and the tray below.

[0056] As shown in Figure 7 In order to adapt to trays of different widths, the distance between the two first clamping cylinders 531 can be adjusted as needed in practice. In order to improve the accuracy of distance adjustment, a scale 55 is placed in the groove 54, and the scale line on the scale 55 can be used to intuitively observe the adjusted distance during adjustment. Alternatively, a certain scale line can be provided on the mounting plate 52 in the clamping direction of the clamping assembly 53. Since the mounting plate 52 is made of metal and is relatively heavy, it is not easy to process scale lines on the mounting plate 52. Therefore, the scale 55 is arranged in the groove 54, which is convenient for installation and processing.

[0057] The unloading position of the feeding conveying and lifting structure 2 and the feeding position of the unloading conveying and lifting structure 3 are both provided with a tray separating structure 6, which comprises a mounting frame 61, a separating cylinder 62 fixedly installed on the mounting frame 61, a second clamping plate 63 installed on the moving end of the separating cylinder 62, and a separating block 64 installed on the side of the second clamping plate 63.

[0058] As shown in Figure 8As shown, the tray carrying device 5 may move the tray below when carrying the top empty tray, thus changing the position of the tray below, and the tray below can be separated from the top tray by the tray separating structure 6, specifically, the second clamping plate 63 is moved by the separating cylinder 62 to make the separating block 64 inserted into the gap between the top tray and the tray below, thus separating the top tray from the tray below, so that the tray below will not be moved when the top empty tray is carried subsequently, in order to improve the tray separating efficiency, the end surface of the separating block 64 towards the tray can be provided as an inclined surface (not marked in the figure), facilitating the insertion between the two trays to complete the tray separating.

[0059] The shape and size of the tray are not limited here, and the skilled in the art can make adaptive design for the convenience of the tray carrying and separating, thus making the carrying and separating more convenient.

[0060] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
