[0100] The present disclosure will be further described in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are merely exemplary and are not intended to limit the disclosure. In addition, it should be noted that only parts related to the present disclosure are shown in the drawings for the purpose of description.

[0101] It should be noted that the embodiments and features in the embodiments of the present disclosure can be combined with each other without conflict.

[0102] Unless otherwise specified, the exemplary embodiments / examples shown will be understood as providing exemplary features of various details that can implement the technical concepts of the present disclosure in practice. Therefore, unless otherwise specified, the features of various embodiments / examples can be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of the present disclosure.

[0103] In the drawings, cross-hatching and / or shading are generally used to make the boundaries of adjacent components clear. Thus, unless otherwise specified, the presence of cross-hatching or shading does not convey or imply any preference or requirement for specific material, material properties, dimensions, proportions, commonality of the illustrated components, and / or any other characteristic, attribute, property, etc. of the components. In addition, in the drawings, the size and relative sizes of components can be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be practiced differently, a specific process sequence can be performed in a different order than described. For example, two consecutively described processes can be performed substantially simultaneously or in reverse order to that described. Furthermore, like reference numerals denote like components throughout the drawings.

[0104] When a component is referred to as being "on", "connected to", or "coupled to" another component, it can be directly on, connected, or coupled to the other component, or intervening components can be present.

[0107] The feeding and discharging system of the present disclosure comprises a tray conveying device 100 and a tray carrying device; the tray conveying device 100 is used to convey the tray to the vicinity of the tray carrying device, the mechanical hand transfers the material on the tray from the tray to the production line, when the material on a certain tray is completely transferred to the production line, the empty tray can be carried to the tray stacking station by the tray carrying device, and the empty tray is discharged at the tray stacking station.

[0108] Figure 1 is a structural schematic diagram of the use state of the tray conveying device according to an embodiment of the present disclosure. Figure 2 is a structural schematic diagram of the use state of the tray conveying device from another angle according to an embodiment of the present disclosure. Figure 3 is a structural schematic diagram of the tray conveying device according to an embodiment of the present disclosure. Figure 4 is a structural schematic diagram of the tray conveying device from another angle according to an embodiment of the present disclosure.

[0109] As shown in Figures 1 to 4 , the tray conveying device 100 of the present disclosure can comprise a bottom plate 110, a first support plate 120, a second support plate 130, a first conveying assembly 140, a second conveying assembly 150, a first driving assembly 160 and the like.

[0110] The bottom plate 110 of the present disclosure is generally formed in a square shape, and comprises a first direction and a second direction. The first direction can be the length direction of the bottom plate 110, and the second direction can be the width direction of the bottom plate 110.

[0111] The first support plate 120 and the second support plate 130 are both slidably arranged on the bottom plate 110. Specifically, two guide rails are arranged on the bottom plate 110, and the two guide rails are arranged in parallel and both along the first direction.

[0112] One end of the first support plate 120 is slidably arranged on one of the two guide rails by a sliding block, and the other end is slidably arranged on the other of the two guide rails by a sliding block. Similarly, one end of the second support plate 130 is slidably arranged on one of the two guide rails by a sliding block, and the other end is slidably arranged on the other of the two guide rails by a sliding block, so that the first support plate 120 and the second support plate 130 can slide on the guide rails, so that the first support plate 120 and the second support plate 130 can approach or move away from each other in the first direction.

[0113] Through the above structure, the length direction of the first support plate 120 and the second support plate 130 of the present disclosure is parallel to the second direction.

[0114] In the present disclosure, when the first support plate 120 and the second support plate 130 are approaching or moving away from each other, one of the first support plate 120 and the second support plate 130 can remain stationary. In a preferred embodiment, the first support plate 120 and the second support plate 130 can move reversely at the same time, so that the first support plate 120 and the second support plate 130 can approach or move away from each other.

[0115] The first conveying assembly 140 is arranged on the first support plate 120 and located on the inner side of the first support plate 120; similarly, the second conveying assembly 150 is arranged on the second support plate 130 and located on the inner side of the second support plate 130. That is, the first conveying assembly 140 and the second conveying assembly 150 of the present disclosure are located in the area between the first support plate 120 and the second support plate 130, so that the tray can be conveyed by the first conveying assembly 140 and the second conveying assembly 150. That is, at this time, a stack of trays (i.e. at least one stack of trays) can be placed on the first conveying assembly 140 and the second conveying assembly 150 and conveyed by the first conveying assembly 140 and the second conveying assembly 150.

[0116] The first driving assembly 160 is used to drive the first support plate 120 and / or the second support plate 130 to move, so that the first support plate 120 and the second support plate 130 can approach or move away from each other, thereby the tray conveying device of the present disclosure can adapt to trays of different sizes; that is, the width between the first support plate 120 and the second support plate 130 of the present disclosure can change with the size of the tray, so that the tray conveying device 100 of the present disclosure can convey trays of different sizes, thereby realizing the compatibility of trays of different sizes.

[0117] Specifically, the first driving assembly 160 of the present disclosure can simultaneously drive the first support plate 120 and the second support plate 130, and make the first support plate 120 and the second support plate 130 have opposite movement directions.

[0118] Specifically, the first driving assembly 160 of the present disclosure can include a first driving motor and a bidirectional screw rod 161 driven to rotate by the first driving motor, and the bidirectional screw rod 161 can be a reverse tooth trapezoidal screw. Specifically, the first driving motor is fixed to the bottom plate 110; both ends of the bidirectional screw rod 161 are rotatably arranged on the bottom plate 110 through bearing seats, and the axis of the bidirectional screw rod 161 is arranged along the first direction, at this time, the bearing seat can limit the axial position of the bidirectional screw rod 161.

[0119] The first support plate 120 is provided with a first nut, and the second support plate 130 is provided with a second nut, the first nut and the second nut have different screw directions, and the first nut and the second nut are matched with the bidirectional screw rod; thus, when the bidirectional screw rod 161 rotates in one direction, the first support plate 120 and the second support plate 130 can approach each other, and when the bidirectional screw rod 161 rotates in the other direction, the first support plate 120 and the second support plate 130 can move away from each other.

[0120] The first conveying assembly 140 and the second conveying assembly 150 are both synchronous belt conveying assemblies, so that the conveying of the trays arranged on the synchronous belts can be realized through the movement of the synchronous belts of the synchronous belt conveying assemblies. In the present disclosure, the first conveying assembly 140 includes a first driving wheel 141 and at least one first driven wheel, and the first driving wheel 141 and the first driven wheel are drivingly connected through a first synchronous belt; similarly, the second conveying assembly 150 includes a second driving wheel 151 and at least one second driven wheel, and the second driving wheel 151 and the second driven wheel are drivingly connected through a second synchronous belt. Since the synchronous belt conveying assembly is a common structure in the art, the structure thereof will not be described in detail in the present disclosure.

[0121] The tray conveying device 100 of the present disclosure further includes a second driving assembly 170 for driving the first conveying assembly 140 and the second conveying assembly 150 to move; that is, the second driving assembly 170 of the present disclosure is provided as one, and the synchronous driving of the first conveying assembly 140 and the second conveying assembly 150 is realized through one second driving assembly 170.

[0122] The second driving assembly 170 includes a second driving motor and a driving shaft 171 driven by the second driving motor, and the cross section of the driving shaft 171 is non-circular, for example, hexagonal. The first driving wheel 141 and the second driving wheel 151 are both slidably arranged on the driving shaft 171 and driven by the driving shaft 171 to rotate.

[0123] Specifically, both ends of the driving shaft 171 are rotatably supported on the bottom plate 110 through a bearing seat, and the axial position of the driving shaft 171 can be limited by the bearing seat, that is, the axis of the driving shaft 171 is arranged in the first direction and cannot move in the first direction.

[0124] The first driving wheel 141 is rotatably supported by a bearing on the first support plate 120, and the driving shaft 171 can slide in the inner hole of the bearing, so that the driving shaft 171 does not affect the movement of the first support plate 120 in the first direction. Similarly, the second driving wheel 151 is rotatably supported by a bearing on the second support plate 130, and the driving shaft 171 can slide in the inner hole of the bearing, so that the driving shaft 171 does not affect the movement of the second support plate 130 in the first direction.

[0125] In a preferred embodiment, the driving shaft 171 comprises a first shaft part and a second shaft part, which are drivingly connected by a coupling 172, at this time, the first shaft part can cooperate with the first driving wheel 141, and the second shaft part can cooperate with the second driving wheel 151, thereby preventing the movement direction deviation of the first support plate 120 and the second support plate 130 from affecting the rotation of the driving shaft 171.

[0126] The tray conveying device 100 of the present disclosure further comprises a lifting assembly 180 for lifting the trays between the first support plate 120 and the second support plate 130, and correspondingly, a stack of trays can be lifted to the feeding station of the feeding and unloading system by the lifting assembly 180.

[0127] Figure 5 is a structural schematic view of the lifting assembly according to an embodiment of the present disclosure.

[0128] Specifically, as shown in Figure 5 the lifting assembly 180 of the present disclosure comprises a lifting driving device 181, an intermediate plate 182, a first tray support 183, a second tray support 184 and the like.

[0129] The lifting driving device 181 can be provided on a bracket, and preferably, the lifting driving device 181 can be an electric cylinder (i.e. an electric sliding table module). The intermediate plate 182 is provided on the lifting driving device 181 to drive the intermediate plate 182 to lift by the lifting driving device 181. In the present disclosure, the intermediate plate 182 is arranged in a vertical plane, and the length direction of the intermediate plate 182 is arranged substantially horizontally.

[0130] The first tray support 183 and the second tray support 184 are both slidably provided on the intermediate plate 182, and the first tray support 183 and the second tray support 184 can approach or move away from each other.

[0131] In the present disclosure, when the first tray support 183 and the second tray support 184 are approaching or moving away from each other, one of the first tray support 183 and the second tray support 184 can remain stationary. In a preferred embodiment, the first tray support 183 and the second tray support 184 can move reversely at the same time, so that the first tray support 183 and the second tray support 184 can approach or move away from each other.

[0132] The third driving assembly 185 is used to drive the first tray support 183 and / or the second tray support 184 to move, so that the first tray support 183 and the second tray support 184 can approach or move away from each other, thereby the tray conveying device of the present disclosure can be adapted to different sizes of trays; that is, the width between the first tray support 183 and the second tray support 184 of the present disclosure can change with the size of the tray, so that the tray conveying device 100 of the present disclosure can convey trays of different sizes, thereby realizing the compatibility of trays of different sizes.

[0133] Specifically, the third driving assembly 185 of the present disclosure can simultaneously drive the first tray support 183 and the second tray support 184, and make the first tray support 183 and the second tray support 184 have opposite movement directions.

[0134] Specifically, the third driving assembly 185 of the present disclosure can include a third driving motor and a bidirectional screw rod driven to rotate by the third driving motor, preferably, the bidirectional screw rod can be a reverse tooth trapezoidal screw. Specifically, the third driving motor is fixed to the middle plate 182; both ends of the bidirectional screw rod are rotatably arranged on the middle plate 182 through bearing seats, and the bidirectional screw rod is arranged along the length direction of the middle plate 182, and the bearing seats can limit the axial position of the bidirectional screw rod.

[0135] The first tray support 183 is provided with a first tray support nut, and the second tray support 184 is provided with a second tray support nut, the first tray support nut and the second tray support nut have different screw directions, and the first tray support nut and the second tray support nut are matched with the bidirectional screw rod; thereby, when the bidirectional screw rod rotates in one direction, the first tray support 183 and the second tray support 184 can approach each other, and when the bidirectional screw rod rotates in the other direction, the first tray support 183 and the second tray support 184 can move away from each other.

[0136] Again referring to Figure 5The first tray support 183 of the present disclosure is provided with a first accommodating groove arranged along the length direction of the first tray support 183 (i.e. along the width direction of the bottom plate 110), and the first front blocking piece 186 and the first rear blocking piece 187 are arranged in the first accommodating groove. The positions of the first front blocking piece 186 and the first rear blocking piece 187 in the first accommodating groove are adjustable, so that the first tray support 183 of the present disclosure can adapt to different sizes of trays. In other words, when the trays are placed between the first front blocking piece 186 and the first rear blocking piece 187, the first front blocking piece 186 and the first rear blocking piece 187 can contact the trays (i.e. the lowermost tray of a stack of trays), so that the first tray support 183 of the present disclosure can stably hold the stack of trays.

[0137] Similarly, the second tray support 184 of the present disclosure is provided with a second accommodating groove arranged along the length direction of the second tray support 184 (i.e. along the width direction of the bottom plate 110), and the second front blocking piece 188 and the second rear blocking piece 189 are arranged in the second accommodating groove. The positions of the second front blocking piece 188 and the second rear blocking piece 189 in the second accommodating groove are adjustable, so that the second tray support 184 of the present disclosure can adapt to different sizes of trays. In other words, when the trays are placed between the second front blocking piece 188 and the second rear blocking piece 189, the second front blocking piece 188 and the second rear blocking piece 189 can contact the trays (i.e. the lowermost tray of a stack of trays), so that the second tray support 184 of the present disclosure can stably hold the stack of trays.

[0138] The first front blocking piece 186 and the first rear blocking piece 187 at least partially protrude from the first tray support 183; similarly, the second front blocking piece 188 and the second rear blocking piece 189 at least partially protrude from the second tray support 184.

[0139] In an embodiment of the present disclosure, the tray conveying device 100 further comprises a tray detection device for detecting the presence signal of the tray. That is, the tray detection device can be used to detect the presence or absence of the tray. In a preferred embodiment, the tray detection device can be a photoelectric sensor, an optical sensor or a diffuse reflection sensor, etc., and can be arranged in multiple positions to detect the tray from multiple positions.

[0140] Referring again to Figure 1 The first support plate 120 of the present disclosure is provided with a first side edge baffle, and the second support plate 130 is provided with a second side baffle, so that a stack of trays can be stably positioned at the position between the first side edge baffle and the second side baffle.

[0141] In addition, the first support plate 120 or the second support plate 130 of the present disclosure is provided with a foolproof block 190 at one end of the first conveying assembly 140 or the second conveying assembly 150, so that the design of the foolproof block 190 allows the tray to enter the tray conveying device 100 only from one direction.

[0142] The bottom plate 110 of the present disclosure is also provided with an inner side baffle 195, which can be provided with a tray detection device, so that the tray detection device can determine whether the tray approaches the inner side baffle 195, and accordingly, the first conveying assembly 140 and the second conveying assembly 150 can slow down and slowly convey a stack of trays to a preset position.

[0143] The tray conveying device of the present disclosure can be compatible with trays of various sizes when in use, so that the automatic production line can be compatible with the production of various products, greatly improving production efficiency and reducing production costs, while also meeting market demand and the trend of product diversification. Moreover, the automatic production line can produce a variety of different products through different programs, accordingly, it can reduce the number of production lines in the factory, reduce the capital expenditure of the factory, and improve production efficiency. In addition, for companies providing automation equipment, the tray conveying device can be provided to most manufacturers, reducing the number of new product development.
