[0036] The following refers to Figures 1 to 5 The first aspect of the utility model embodiment is described in detail.

[0037] Reference Figure 1 And Figure 2 According to the utility model embodiment, a conveying module comprises a conveying mechanism 100 and a material taking mechanism 200, the conveying mechanism 100 is used for conveying a material tray, a containing space 100b is formed below the conveying surface 100a of the conveying mechanism 100, the material taking mechanism 200 is arranged in the containing space 100b, the material taking mechanism 200 comprises a driving assembly 210 and a material taking assembly 220, the material taking assembly 220 is used for grabbing or releasing the material tray, the driving assembly 210 is drivingly connected with the material taking assembly 220, and is used for driving the material taking assembly 220 to enter or exit the containing space 100b and driving the material tray to move to the conveying surface 100a.

[0038] In the working process of the conveying module of the present application, first, the tray is grabbed by the material taking assembly 220, then the material taking assembly 220 is driven to move by the driving assembly 210 connected with the material taking assembly 220, so that the tray grabbed by the material taking assembly 220 moves to the conveying surface 100a, at this time the material taking assembly 220 releases the tray, the tray falls on the conveying surface 100a, then the driving assembly 210 drives the material taking assembly 220 to enter the accommodating space 100b below the conveying surface 100a, the tray continues to move on the conveying surface 100a under the action of the conveying mechanism 100, then the driving assembly 210 drives the material taking assembly 220 to leave the accommodating space 100b, so as to return to the position of grabbing the tray and continue to grab the next tray. It can be known from the above working process that the accommodating space 100b below the conveying mechanism 100 accommodates and moves the material taking mechanism 200, improves the space utilization, makes the structure of the conveying module more compact, so that the conveying module as a whole occupies less space.

[0039] Reference Figure 2 and Figure 3 In some embodiments of the present application, the material taking assembly 220 comprises the clamping jaw 221 and the first driving structure 222 connected with each other, and the first driving structure 222 is used to drive the clamping jaw 221 to grab or release the tray. It can be understood that the clamping jaw 221 grabs the tray by the first driving structure 222, then the clamping jaw 221 is driven to move by the driving assembly 210, so as to drive the tray grabbed by the clamping jaw 221 to move to the conveying surface 100a, at this time the first driving structure 222 drives the clamping jaw 221 to release the tray, and the material taking assembly 220 is driven to move into the accommodating space 100b by the driving assembly 210, so that the tray can move along the conveying surface 100a without obstruction under the action of the conveying mechanism 100.

[0040] Specifically, the first driving structure 222 is connected with the driving assembly 210, and the driving assembly 210 drives the first driving structure 222 to move, thereby driving the clamping jaw 221 to move.

[0041] In some other embodiments of the present application, in addition to the clamping jaw 221 and the first driving structure 222 cooperating to grab the tray as described above, a suction cup, a hook or the like can also be used to grab the tray.

[0042] In some embodiments, the clamping jaw 221 comprises a plurality of clamping blocks 221a, the plurality of clamping blocks 221a jointly define a clamping area 221b for clamping the tray, and a protrusion 221c is arranged on the side surface of the clamping block 221a close to the clamping area 221b, which is matched with the clamping groove of the tray. For example, as shown in Figure 3As shown, the clamping jaw 221 comprises two clamping blocks 221a distributed in the vertical direction, a clamping area 221b is formed between the two clamping blocks 221a, and the two clamping blocks 221a are respectively connected with the first driving structure 222. The first driving structure 222 can drive the two clamping blocks 221a to approach or move away from each other in the vertical direction to enter or leave the clamping groove of the tray.

[0043] It can be understood that, by connecting the two clamping blocks 221a with the first driving structure 222, when the first driving structure 222 drives the two clamping blocks 221a to approach each other in the vertical direction, the protrusions 221c on the two clamping blocks 221a enter the tray clamping groove from above and below respectively, at which time the clamping jaw 221 grabs the tray; when the first driving structure 222 drives the two clamping blocks 221a to move away from each other in the vertical direction, the protrusions 221c on the two clamping blocks 221a exit the tray clamping groove from above and below respectively, at which time the clamping jaw 221 releases the tray. It can be understood that, by cooperating the protrusions 221c of the upper and lower clamping blocks 221a with the clamping groove, the possibility of the tray disengaging from the clamping jaw 221 during movement is reduced.

[0044] In some embodiments of the present application, the conveying mechanism 100 comprises a plurality of conveying belts 110 arranged side by side, the upper surfaces of the plurality of conveying belts 110 jointly form a conveying surface 100a, a relief area 110a is formed between two adjacent conveying belts 110, the relief area 110a is in communication with the accommodating space 100b; the material taking mechanism 200 can pass through the relief area 110a and can move in the conveying direction within the relief area 110a.

[0045] It can be understood that after the material taking assembly 220 picks up the tray, the driving assembly 210 drives the material taking assembly 220 to move forward in the avoiding area 110a, so that the picked tray is moved to the upper surface of the two conveying belts 110, at this time, the material taking assembly 220 releases the tray, the driving assembly 210 drives the material taking assembly 220 to pass through the avoiding area 110a and return to the containing space 100b, the material taking assembly 220 moves backward in the containing space 100b under the driving of the driving assembly 210, and passes through the avoiding area 110a to return to the position of picking up the tray, so as to pick up the next tray to the conveying belt 110. The avoiding area 110a formed between the conveying belts 110 can provide a moving channel for the material taking assembly 220 to move along the avoiding area 110a after picking up the tray, so that the tray can move above the conveying surface 100a, and after the material taking assembly 220 releases the tray, the tray can normally fall on the conveying surface 100a. At the same time, the avoiding area 110a is connected with the containing space 100b, which can facilitate the material taking assembly 220 to enter and exit the containing space 100b in the height direction, and after the material taking assembly 220 places the tray on the conveying surface 100a, the material taking assembly 220 descends in the height direction, that is, can pass through the avoiding area 110a and enter the containing space 100b.

[0046] In some embodiments, the driving assembly 210 comprises a second driving structure 211 and a third driving structure 212, the second driving structure 211 and the third driving structure 212 are respectively connected with the material taking assembly 220, the second driving structure 211 is used to drive the material taking assembly 220 to reciprocate along the conveying direction parallel to the conveying belt 110, and the third driving structure 212 is used to drive the material taking assembly 220 to move in the vertical direction, so as to drive the material taking assembly 220 to pass through the avoiding area 110a. For example, as shown in Figure 2 the second driving structure 211 is connected with the material taking assembly 220, the third driving structure 212 is connected with the second driving structure 211, the second driving structure 211 can drive the material taking assembly 220 to reciprocate in the front-back direction, and the third driving structure 212 can drive the second driving structure 211 to move in the vertical direction.

[0047] It can be understood that when the material taking assembly 220 grabs the tray, the material taking assembly 220 is driven to move forward by the second driving structure 211 to drive the tray grabbed by the material taking assembly 220 to move to the upper surface of the conveying belt 110, and then the material taking assembly 220 releases the tray, the material taking assembly 220 is driven to move downward by the third driving structure 212 to pass through the avoiding area 110a and return to the containing space 100b, at this time, the tray can be conveyed forward smoothly under the driving of the conveying belt 110, the material taking assembly 220 is driven to move backward to the position below the tray to be grabbed by the second driving structure 211, and the material taking assembly 220 is driven to move upward and pass through the avoiding area 110a by the third driving structure 212 to return to the position of the tray to be grabbed to wait for grabbing the next tray.

[0048] In a further embodiment of the present application, the second driving structure 211 is a rodless cylinder, the driving assembly 210 further comprises a fourth driving structure 213, the fourth driving structure 213 is connected with the material taking assembly 220, and the fourth driving structure 213 can drive the material taking assembly 220 to move in the front-back direction, so that the tray can be located in the clamping area 221b or completely separated from the clamping area 221b.

[0049] It can be understood that when the material taking assembly 220 moves upward to the conveying surface 100a by the third driving structure 212, the tray is separated from the material taking assembly 220 by a certain distance, the material taking assembly 220 is driven to move backward by the fourth driving structure 213, so that the tray enters the clamping area 221b of the material taking assembly 220, at this time, the material taking assembly 220 can grab the tray; when the material taking assembly 220 is driven to move forward by the second driving structure 211, so that the tray grabbed by the material taking assembly 220 is located on the conveying surface 100a, the material taking assembly 220 releases the tray, at this time, the tray is still located in the clamping area 221b, the material taking assembly 220 is driven to move forward by the fourth driving structure 213, so that the tray completely separates from the clamping area 221b, at this time, the third driving structure 212 can smoothly drive the material taking assembly 220 to move downward and return to the containing space 100b.

[0050] Specifically, the second driving structure 211 is a rodless cylinder, the output end of the rodless cylinder is connected with the fourth driving structure 213, and the fourth driving structure 213 can be driven to move in the front-back direction; the third driving structure 212 is a vertical driving cylinder, the output end of the vertical cylinder is connected with the second driving structure 211, and the second driving structure 211 can be driven to move in the vertical direction; the fourth driving structure 213 is a horizontal driving cylinder, the output end of the horizontal driving cylinder is connected with the first driving structure 222, and the first driving structure 222 can be driven to move in the front-back direction.

[0051] It can be understood that the driving structure in the application adopts a cylinder, which reduces the manufacturing cost of the application and reduces the working energy consumption of the conveying device.

[0052] In some embodiments of the application, the conveying module further comprises a guide mechanism 300, which is arranged on one side of the conveying mechanism 100. The guide mechanism 300 is adjustably arranged in a direction perpendicular to the conveying direction of the conveying mechanism 100, and is used to guide the movement of the tray on the conveying surface 100a in the conveying direction. For example, as shown in Figure 1 and Figure 4 The conveying module further comprises two guide mechanisms 300, which are arranged on both sides of the conveying mechanism 100 in the left-right direction. The guide mechanisms 300 are adjustably arranged in the left-right direction.

[0053] It can be understood that when the tray moves on the conveying surface 100a, the position of the guide mechanism 300 is adjusted in the left-right direction to ensure that the guide mechanism 300 guides the movement of the tray, thereby reducing the positional deviation of the tray in the left-right direction during movement on the conveying surface 100a, thereby affecting the possibility of subsequent feeding.

[0054] Specifically, the conveying module further comprises a mounting bracket 500, and the guide mechanism 300 comprises a guide piece 320 extending in the front-rear direction. A plurality of long holes 321 are arranged on the guide piece 320 in the front-rear direction, and the long holes 321 extend in the left-right direction. A threaded connecting piece is slidably arranged in the long hole 321, and the threaded connecting piece is threadedly connected with the mounting bracket 500. It can be understood that by moving the guide piece 320 in the left-right direction to make the threaded connecting piece slide in the long hole 321, and then by screwing the threaded connecting piece, the guide piece 320 is fixed on the mounting bracket 500 through the threaded connecting piece, thereby realizing the position adjustment of the guide mechanism 300 in the left-right direction.

[0055] In some embodiments, the guide mechanism 300 comprises a plurality of rollers 310 arranged in the conveying direction and used to slide with the tray on the conveying surface 100a. For example, as shown in Figure 1 and Figure 4 The guide mechanism 300 comprises a plurality of rollers 310 arranged in the front-rear direction. It can be understood that by sliding the plurality of rollers 310 with the tray on the conveying surface 100a, the tray can be guided to move in the front-rear direction, and the friction between the tray and the guide mechanism 300 is reduced.

[0056] Specifically, the roller 310 is rotatably arranged on the guide piece 320 in the vertical direction.

[0057] In some embodiments of the utility model, the conveying module further comprises a positioning mechanism 400, the positioning mechanism 400 is arranged on one side of the conveying mechanism 100, and the positioning mechanism 400 can position or unposition the tray on the conveying surface 100a.

[0058] It can be understood that the tray on the conveying surface 100a is positioned by the positioning mechanism 400, and the possibility that the tray continues to move forward under the action of inertia when the conveying belt 110 stops running can be reduced.

[0059] As shown in Figure 1 And Figure 5 In some embodiments, the positioning mechanism 400 comprises a first driver 410 and a stop block 420, the first driver 410 is connected with the stop block 420, and the first driver 410 is used for driving the stop block 420 to approach or move away from the conveying mechanism 100, and when the stop block 420 approaches the conveying mechanism 100, the stop block 420 can hinder the tray from continuing to move along the conveying direction of the conveying mechanism 100. It can be understood that when the tray is moved to the feeding area under the driving of the conveying belt 110, the left and right two first drivers 410 drive the stop blocks 420 connected with the first drivers 410 to approach the conveying belt 110, and the stop blocks 420 are partially arranged above the conveying belt 110, the tray continues to move and abuts against the stop blocks 420, the left and right two stop blocks 420 hinder the tray from continuing to move forward, and the tray is positioned in the feeding area.

[0060] It can be understood that by arranging two stop blocks along the left-right direction, when the stop blocks approach and abut against the tray, the left and right sides of the right end of the tray can be respectively attached to the two stop blocks, so that the spatial posture of the tray in the feeding area is adjusted.

[0061] The following references are made to Figure 6The second aspect embodiment of the utility model discloses a kind of feeding device, which is described in detail.
