The first feature "below", "below" and "below" the second feature include the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] 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.

[0038] like Figures 1 to 6 As shown, this embodiment provides a double-layer loading device, which is installed upstream of the assembly equipment. The two moving parts 210 in the double-layer loading device can move to the unloading end 102 of the bracket 100 successively. The gripping end of the manipulator in the assembly equipment can grab the workpiece from the unloading end 102 and assemble it with other workpieces. The two moving parts 210 can make the unloading end 102 always have workpieces when the manipulator moves to the unloading end 102, and there is no need for the assembly equipment to wait, thereby improving the assembly efficiency. Among them, the gripping end of the manipulator can move in three-dimensional space.

[0039] The double-layer loading device includes a bracket 100 and a moving component 200, wherein the bracket 100 has a material receiving end 101 and a material unloading end 102; at least two moving components 200 are provided, and at least two moving components 200 are arranged at intervals in the vertical direction. The moving component 200 includes a moving member 210 and a driving member 220, and the driving member 220 is arranged on the bracket 100. The moving member 210 is slidably arranged on the bracket 100 along a first direction, and is transmission-connected to the output end of the driving member 220.

[0040] At least two moving parts 210 in at least two moving assemblies 200 slide alternately between the receiving end 101 and the unloading end 102 of the bracket 100, and the interval time from the first moving part 210 leaving the unloading end 102 to the second moving part 210 sliding to the unloading end 102 is less than the assembly time of the assembly equipment. That is, from the time when the first moving part 210 leaves the unloading end 102 to the time when the second moving part 210 moves to the unloading end 102, the interval time between the first moving part 210 leaving the unloading end 102 and the second moving part 210 moving to the unloading end 102 is less than the time required for the assembly equipment to assemble a product. This arrangement allows the workpiece to wait for the arrival of the manipulator at the unloading end 102, that is, the assembly equipment does not need to wait for the arrival of the workpiece at the unloading end 102, thereby improving the assembly efficiency.

[0041] In the present embodiment, the two moving parts 210 in the two moving assemblies 200 are respectively defined as a first transfer part and a second transfer part, wherein the moving trajectory of the first transfer part is located below the moving trajectory of the second transfer part. In conjunction with the robotic arm of the assembly equipment, since the grabbing end of the robotic arm can grab the workpiece in the transfer parts at different heights, there is no need for the first transfer part or the second transfer part to have a lifting function, thereby simplifying the structure of the double-layer loading device and reducing costs.

[0042] To facilitate the splicing of multiple bases 110, in some embodiments, the bracket 100 includes at least two bases 110, and at least two bases 110 are sequentially detachably connected in the vertical direction, wherein each movable assembly 200 is respectively arranged on each corresponding base 110. In this embodiment, the two bases 110 are detachably connected in the vertical direction. In other embodiments, three bases 110 may be provided, and the three bases 110 are spaced apart in the vertical direction, and three movable assemblies 200 are spaced apart in the vertical direction, and each movable assembly 200 is respectively arranged on each corresponding base 110.

[0043] In some embodiments, the base 110 includes a support plate 111 and a support leg 112 disposed on the lower side of the support plate 111. In two adjacent bases 110, the support plate 111 of the upper base 110 is provided with an avoidance portion to avoid the lower moving member 210. Exemplarily, in the upper base 110, two support plates 111 are provided, and the two support plates 111 are spaced apart along the second direction, and an avoidance portion is formed between the two support plates 111. The provision of the support leg 112 keeps the bottom support plate 111 away from the ground to prevent the moving assembly 200 from getting wet, and provides a certain gap between two adjacent support plates 111 to facilitate the assembly of the moving assembly 200; in addition, the provision of the avoidance portion minimizes the distance between adjacent support plates 111, which helps to reduce the size of the double-layer feeding device in the vertical direction and reduce costs.

[0044] In order to prevent the moving member 210 from moving ineffectively between the material receiving end 101 and the material discharging end 102, that is, to prevent the moving member 210 from moving toward the material discharging end 102 before completing the material receiving, or moving toward the material receiving end 101 before completing the material discharging, in some embodiments, the moving assembly 200 further includes a bearing member 230 and a first detection member 240. The bearing member 230 is disposed on the moving member 210 and is used to carry the workpiece; the first detection member 240 is disposed on the moving member 210 and is used to detect the workpiece on the bearing member 230. This arrangement ensures that the moving member 210 will move toward the material discharging end 102 only when a workpiece is detected on the bearing member 230 at the material receiving end 101, and will move toward the material receiving end 101 only when no workpiece is detected on the bearing member 230 at the material discharging end 102.

[0045] One first detection member 240 can be provided, and the first detection member 240 is installed on the moving member 210 and follows the movement of the moving member 210, and can detect the workpiece on the carrier 230 when the moving member 210 is located at the material receiving end 101, and can also detect the workpiece on the carrier 230 when the moving member 210 is located at the material discharging end 102. Two first detection members 240 can also be provided, wherein one first detection member 240 is provided at the material receiving end 101 of the bracket 100, and the other first detection member 240 is provided at the material discharging end 102 of the bracket 100.

[0046] It should be noted that the first detection member 240 is in communication connection with the controller. When the moving member 210 is located at the receiving end 101, the first detection member 240 sends a workpiece signal to the controller when detecting the workpiece, and the controller controls the driving member 220 to drive the moving member 210 to move to the unloading end 102. When the moving member 210 is located at the unloading end 102, after the workpiece manipulator grabs it, the first detection member 240 sends a workpiece-free signal to the controller when it cannot detect the workpiece, and the controller controls the driving member 220 to drive the moving member 210 to move to the receiving end 101.

[0047] The double-layer loading device also includes a second detection member 300, which is provided in plurality and corresponds to at least two carriers 230 respectively. The plurality of second detection members 300 corresponding to the same carrier 230 are arranged at intervals along the second direction. The carrier 230 is provided with a plurality of models, and the carrier 230 has a detection hole 231. The detection holes 231 of the carriers 230 of different models are located at different positions, and the detection holes 231 on the carriers 230 of the same model are selectively opposite to the plurality of second detection members 300. Exemplarily, there are eight second detection members 300, wherein one upper carrier 230 corresponds to four second detection members 300, and one of the four second detection members 300 is directly opposite to the position of the detection hole 231, so as to determine the model of the carrier 230, thereby determining the model of the workpiece; similarly, one lower carrier 230 corresponds to four second detection members 300, which are used to detect the model of the lower carrier 230 to determine the model of the workpiece.

[0048] The double-layer feeding device further includes a detection support 310, which is disposed on the bracket 100, and a plurality of second detection members 300 corresponding to the same bearing member 230 are spaced apart along the second direction on the detection support 310. The second detection members 300 are provided in two groups, each group is provided with a plurality of second detection members 300, and each group of second detection members 300 corresponds to each bearing member 230, wherein each group of second detection members 300 is spaced apart along the vertical direction to complete the detection of the model of the bearing member 230 on each moving member 210.

[0049] The first direction is the front-to-back direction, the second direction is the left-to-right direction, and the vertical direction is the up-down direction. The first direction, the second direction and the vertical direction are perpendicular to each other.

[0050] To ensure that the moving part 210 can stop in time at the material receiving end 101 and the material discharging end 102, in some embodiments, the moving component 200 also includes an upper limit switch 410 and a lower limit switch 420. The upper limit switch 410 and the lower limit switch 420 are arranged on the bracket 100 at intervals along the first direction, and are used to stop the moving part 210 at the material receiving end 101 and the material discharging end 102, respectively.

[0051] like Figure 2 As shown, when the movable member 210 is located at the material receiving end 101, the loading mechanism will need to place the workpiece on the carrier 230, but the specific position of the movable member 210 directly affects the placement accuracy of the workpiece. For this reason, in some embodiments, the movable member 210 is provided with an upper limit screw hole, and the movable assembly 200 also includes an upper limit screw 250, and the upper limit screw 250 is threadedly matched with the upper limit screw hole, and the distance between the nut of the upper limit screw 250 and the movable member 210 is adjustable. When the movable member 210 is located at the material receiving end 101, the upper limit switch 410 and the nut of the upper limit screw 250 abut against each other. By adjusting the distance between the nut of the upper limit screw 250 and the movable member 210, the specific position of the movable member 210 at the material receiving end 101 when the nut abuts against the upper limit switch 410 can be adjusted, thereby facilitating the precise docking of the movable member 210 with the loading mechanism.

[0052] Similarly, to ensure that the robot can accurately grasp the workpiece located at the unloading end 102, a unloading limit hole is provided on the moving part 210, and the moving component 200 also includes a lower limit screw, which is threadedly matched with the lower limit screw hole. When the moving part 210 is located at the unloading end 102, the lower limit switch 420 and the nut of the lower limit screw are in contact.

[0053] In some embodiments, the moving assembly 200 further includes a plug-in component 260 and a matching component 270, one of which is disposed on the moving component 210, and the other is disposed on the output end of the driving component 220, the plug-in component 260 is provided with a plug-in portion 261 extending along the second direction, the matching component 270 is provided with a plug-in hole, the plug-in portion 261 can be plugged into the plug-in hole, and the first direction and the second direction are perpendicular. Wherein, the driving component 220 includes a linear cylinder, the output end of the linear cylinder is provided with a drag block 221, the drag block 221 can reciprocate along the first direction, and the matching component 270 is fixed on the drag block 221.

[0054] like Figure 3 and Figure 4The moving assembly 200 also includes a pad 280, which is sandwiched between the fitting 270 and the drag block 221. The fitting 270 is provided with a plug-in slot, and the pad 280 blocks the plug-in slot to form a plug-in hole. The provision of the pad 280 is conducive to improving the connection stability between the fitting 270 and the drag block 221; in addition, the plug-in portion 261 is in contact with the pad 280, thereby avoiding friction on the drag block 221 and improving its service life. The pad 280 can be made of rubber or stainless steel. The fixing screw passes through the fitting 270 and the pad 280 in sequence and then engages with the fixing hole thread on the drag block 221.

[0055] like Figure 5 and Figure 6 As shown, in order to reduce the height of the double-layer feeding device, in some embodiments, the driving member 220 is arranged on the left or right side of the moving member 210. The matching member 270 in the moving component 200 is provided with a connecting groove 271, and the connecting groove 271 is provided with a connecting port toward the plug-in member 260, and has an upper opening, and the upper opening passes through the matching member 270 upward, and the plug-in portion 261 of the plug-in member 260 is plugged into the connecting groove 271 from the connecting port. In this embodiment, the support plate 111 in the upper moving component 200 blocks the upper opening of the connecting groove 271 of the lower moving component 200.

[0056] In order to improve the smoothness of the sliding of the moving member 210 along the first direction and reduce the resistance of the driving member 220, in some embodiments, the moving assembly 200 further includes a slide rail 291 and a slider 292, the slide rail 291 is provided on the support plate 111, and the slider 292 is provided on the moving member 210 and slides with the slide rail 291. Each moving assembly 200 includes two slide rails 291 and two sliders 292, the two slide rails 291 are spaced apart along the second direction, and the two sliders 292 are respectively provided at both ends of the moving member 210 and slide with the corresponding slide rails 291.

[0057] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
