Referring to fig. 1 and 4, an embodiment of the present invention provides a blanking device, which has a feeding station, a detecting station and a blanking station. The blanking device comprises a turntable mechanism 20, a blanking mechanism 10, a detection mechanism and a transfer mechanism 40.

The turntable mechanism 20 includes a turntable 21 rotatably disposed about its axis and a clamp 22 disposed on the turntable 21. The clamp 22 can pass through the feeding station, the detection station and the blanking station in sequence in the process of rotating along with the turntable 21. The blanking mechanism 10 is arranged in correspondence with the loading station for transferring the product of the previous process (for example, the winding device described below) to the gripper 22 located at the loading station. The detection mechanism is arranged corresponding to the detection station and is used for detecting the product on the clamp 22 of the detection station; the transfer mechanism 40 is arranged corresponding to the blanking station and is used for transferring and outputting the products on the clamp 22 of the blanking station.

When the product is formed, the turntable 21 of the turntable mechanism 20 rotates to the clamp 22 and is located at the feeding station, and at this time, the blanking mechanism 10 transfers the formed product to the clamp 22 located at the feeding station, and the clamp 22 clamps the product. Then the turntable 21 of the turntable mechanism 20 rotates until the clamp 22 is located at the detection station, and the detection mechanism detects the product on the clamp 22. After the detection is finished, the turntable 21 of the turntable mechanism 20 rotates until the clamp 22 is located at the blanking station, and at this time, the transfer mechanism 40 transfers and outputs the product on the clamp 22.

In the prior art, products are conveyed along a horizontal straight line by utilizing a conveying line (such as a belt conveyor), and all mechanisms are sequentially arranged along the conveying line, so that the conveying direction along the conveying line is overlarge in size, larger space is occupied, and the arrangement of other mechanisms is influenced. However, the blanking device of the present application, by providing the turntable mechanism 20 and disposing the blanking mechanism 10, the detection mechanism and the transfer mechanism 40 around the turntable mechanism 20, makes the layout more compact, reduces the space required to be occupied, and facilitates the arrangement of other mechanisms.

Referring to fig. 1, 2 and 3, in an embodiment of the present invention, the blanking mechanism 10 includes a rotary base 11 and a first grabbing assembly 12. The rotary base 11 is rotatably arranged around the axis of the rotary base, and the first grabbing component 12 is arranged on the rotary base 11 and can rotate together with the rotary base 11. The process of the first grabbing component 12 rotating along with the rotating base 11 includes a first grabbing position and a first releasing position. The first gripper assembly 12, when in the first gripping position, may grip a product from a previous process (e.g., a winding device as described below). When the first gripper assembly 12 is in the first release position, the gripped products may be released to the gripper 22 at the loading station. In this way, the first grabbing assembly 12 is driven to rotate back and forth between the first grabbing position and the first releasing position by the rotation of the rotary base 11, so that the product at the first grabbing position is transferred to the clamp 22 at the first releasing position for clamping, that is, the transfer of the product is realized by the rotation motion, which is beneficial to saving the occupied space compared with the linear motion in the prior art. Alternatively, the rotation axis of the rotary seat 11 is parallel to the rotation axis of the turntable 21 and parallel to the first direction described below, further simplifying the structure of the device and saving the required occupied space.

Specifically, in the embodiment, the first grabbing assembly 12 includes a first fixing seat 121, a first telescopic driving element 122 and a first grabbing hand 123. The first fixing base 121 is connected to the rotating base 11 to rotate synchronously with the rotating base 11. The first telescopic driving member 122 is disposed on the first fixing seat 121, the first gripper 123 is mounted at a driving end of the first telescopic driving member 122, so that the first telescopic driving member 122 drives the first gripper 123 to extend and retract along a radial direction of the rotating seat 11, and the first gripper 123 is used for gripping or releasing a product. Thus, when the first gripper 123 rotates to the first gripping position along with the rotary base 11, the first telescopic driving member 122 drives the first gripper 123 to extend toward the product to grip the product, and after the gripping is completed, the first telescopic driving member 122 drives the first gripper 123 to retract, so as to prevent the first gripper 123 from interfering when the rotary base 11 rotates. When the first gripper 123 rotates with the rotary base 11 to the first release position, the first telescopic driving member 122 drives the first gripper 123 to extend toward the clamp 22 so as to release the product to the clamp 22 to be clamped by the clamp 22, and then the first telescopic driving member 122 drives the first gripper 123 to retract so as to prevent the first gripper 123 from interfering when the rotary base 11 rotates. Alternatively, the first telescopic drive 122 may be a pneumatic cylinder. The first hand grip 123 may adopt a structure of a clamping jaw cylinder and a clamping jaw, and may also adopt other gripping structures, which are not limited herein.

Further, the first grabbing assembly 12 further comprises an adjusting seat 124 and a first adjusting driving member 125, the first adjusting driving member 125 is mounted at the driving end of the first telescopic driving member 122 through the adjusting seat 124, and the first grabbing hand 123 is mounted at the driving end of the first adjusting driving member 125 so as to be driven by the first adjusting driving member 125 to move along a direction parallel to the rotation axis of the rotating seat 11 (i.e. the axial direction of the product). For products with different specifications, the axial lengths of the products are different, so that the axial middle positions of the products are different, the first adjusting driving piece 125 is used for driving the first hand grip 123 to move, the first hand grip 123 is aligned to the axial middle position of the products, the first hand grip 123 can be guaranteed to grip the products in a centering manner, the products with different dimensions are compatible, and the applicability of the blanking device is enhanced. Alternatively, the first adjustment drive 125 may be a pneumatic cylinder.

In the specific embodiment, the blanking mechanism 10 further includes a first driving assembly 13 for driving the rotary seat 11 to rotate around its axis. The first driving assembly 13 includes a rotary supporting base 131, a second fixing base 132 and a rotary driving member 133. The rotary base 11 is rotatably connected to the rotary support base 131 about its axis. The rotation driving member 133 is mounted on the second fixing seat 132 and is in transmission connection with the rotating seat 11 to drive the rotating seat 11 to rotate around its axis. Alternatively, the rotary drive 133 may be a motor.

Further, the rotary base 11 is mounted to the rotary support base 131 through the first rotary shaft 134, that is, the first rotary shaft 134 is rotatably mounted to the rotary support base 131, and the rotary base 11 is fixedly connected to the first rotary shaft 134 so as to rotate synchronously with the first rotary shaft 134. The first rotating shaft 134 is in transmission connection with the rotating driving member 133 through a belt transmission structure, so that the rotating driving member 133 drives the first rotating shaft 134 to rotate through the belt transmission structure, and further drives the rotating base 11 to rotate. Of course, in other embodiments, the first rotating shaft 134 may also be in transmission connection with the rotating driving member 133 through other transmission structures, such as a gear transmission structure, a coupling, etc., which are not limited herein.

Referring to fig. 1, 4 and 5, in an embodiment of the present invention, the turntable mechanism 20 further includes a second driving assembly 23 for driving the turntable 21 to rotate around its axis. The second driving assembly 23 includes a third fixing seat 231, a turntable driving member 232 and a supporting seat 233. The turntable driving member 232 is mounted on the third fixing seat 231, and the turntable 21 is rotatably connected to the supporting seat 233 around its own axis and is in transmission connection with the turntable driving member 232, so that the turntable driving member 232 can drive the turntable 21 to rotate around its own axis. Alternatively, the turntable drive 232 may be a motor.

Further, the rotating plate 21 is connected to the supporting base 233 through the second rotating shaft 234, that is, the second rotating shaft 234 is rotatably connected to the supporting base 233, and the rotating plate 21 is fixedly connected to the second rotating shaft 234 to rotate synchronously with the second rotating shaft 234. The turntable driving member 232 can be in transmission connection with the second rotating shaft 234 through a coupling. Of course, in other embodiments, the turntable driving member 232 can also be in transmission connection with the second rotating shaft 234 through a belt transmission structure, a gear transmission structure, etc., which is not limited herein.

In particular, in the embodiment, the plurality of clamps 22 may be provided, and the plurality of clamps 22 may be uniformly arranged around the rotation axis of the turntable 21, thereby improving the working efficiency.

In the embodiment of the present invention, the clamp 22 has a clamping state for clamping the product and a loosening state for loosening the product. The blanking device also comprises an unlocking assembly 80 which is respectively arranged corresponding to the feeding station and the blanking station, and the unlocking assembly 80 can controllably trigger the clamp 22 positioned at the feeding station or the blanking station so that the clamp 22 is converted into a loosening state from a clamping state. When the gripper 22 rotates with the turntable 21 to the loading station, the unlocking assembly 80 corresponding to the loading station triggers the gripper 22 to the released state so as to receive the product released by the blanking mechanism 10. The release assembly 80 then releases the trigger on the clamp 22 and the clamp 22 returns from the undamped condition to the clamped condition. When the clamp 22 rotates with the turntable 21 to the blanking station, the unlocking assembly 80 corresponding to the blanking station triggers the clamp 22 to a released state so that the transfer mechanism 40 can grasp the product. So, utilize unblock subassembly 80 to be in the unclamping state at material loading station and unloading station trigger anchor clamps 22, be in the clamping state at other stations or pivoted in-process, guarantee the stability of product clamping to anchor clamps 22 need not install the driving source, have simplified anchor clamps 22's structure.

In a specific embodiment, the unlocking assembly 80 includes an unlocking bracket 81, an unlocking driving member 82 disposed on the unlocking bracket 81, and an unlocking member 83 disposed at a driving end of the unlocking driving member 82, and the unlocking member 83 is driven by the unlocking driving member 82 to move to abut against or separate from the jig 22. When the unlocking member 83 abuts on the clamp 22, the clamp 22 is triggered to the released state, and when the unlocking member 83 is separated from the clamp 22, the clamp 22 is released from being triggered to return to the clamped state. Alternatively, the unlock drive 82 may be a cylinder.

Referring to fig. 6 and 7, in an embodiment of the present invention, the clamp 22 includes a base 221, a clamping jaw assembly 222, an elastic member 223, and a third driving assembly 224. The two jaw assemblies 222 include two, the two jaw assemblies 222 are movably connected to the base 221 along a first predetermined direction (in the embodiment shown in fig. 6, the first predetermined direction is a left-right direction), and the two jaw assemblies 222 are arranged at intervals along the first predetermined direction, and form a clamping position a for clamping a product between the two jaw assemblies 222. The elastic member 223 is connected to the two jaw assemblies 222 to provide a pre-tightening force for approaching the two jaw assemblies 222, so that the two jaw assemblies 222 clamp the product in the clamping position a under the pre-tightening force provided by the elastic member 223, and the clamp 22 is in the clamping state. The third driving element 224 is disposed on the base 221 and can extend between the two clamping jaw elements 222 under the action of an external force to provide a driving force for moving the two clamping jaw elements 222 away from each other. Alternatively, the elastic member 223 may be a spring.

In this manner, the clamp 22 causes the two jaw assemblies 222 to clamp the product via the resilient members 223. When the third driving assembly 224 extends between the two jaw assemblies 222 under the action of an external force, a driving force for separating the two jaw assemblies 222 is provided, and under the action of the driving force, the two jaw assemblies 222 synchronously move away from each other against the pre-tightening force of the elastic member 223, so that the product is clamped, and the clamp 22 is in a released state. Compared with the prior art, the clamp 22 avoids the use of a clamping jaw cylinder, and the clamping action is stable and reliable.

It should be noted that the clamp 22 can keep clamping the product under the action of the elastic member 223, and when the loading station and the unloading station of the product need to be placed or taken out, the unlocking member 83 of the unlocking member 80 is adopted to push the third driving member 224, so that the clamp 22 releases the product, and a driving source is not required to be arranged on the clamp 22, so that the structure is simpler and more compact, the arrangement of related mechanisms around the clamp 22 is facilitated, and the overall layout optimization of the unloading device is facilitated.

In one embodiment of the present invention, the third driving assembly 224 includes a driving rod 2241 and two connecting rods 2242. Drive bar 2241 is movably coupled to base 221, two links 2242 are hingedly coupled at one end to drive bar 2241, and two links 2242 are hingedly coupled at the other end to jaw assemblies 222, respectively. During the movement of the driving rod 2241, the driving rod 2241 can extend between the two jaw assemblies 222, so as to drive the two connecting rods 2242 to spread the two jaw assemblies 222, so that the two jaw assemblies 222 move away from each other, and the product is released (i.e. the clamp 22 is in the release state). When the external force disappears, the two jaw assemblies 222 move close to each other under the action of the pre-tightening force of the elastic member 223 to clamp the product, and the driving rod 2241 is pushed to exit between the two jaw assemblies 222. Alternatively, the driving lever 2241 is movably coupled to the base 221 in a second predetermined direction perpendicular to the first predetermined direction. In the embodiment shown in fig. 6, the second predetermined direction is an up-down direction. It should be noted that the unlocking member 83 of the unlocking assembly 80 can be used to push the driving rod 2241 of the third driving assembly 224 to extend into the space between the two jaw assemblies 222 along the second direction, so that the clamp 22 can release the product.

In particular embodiments, the movement of the drive bar 2241 includes a clamping position and a release position. The angle between the two link bars 2242 when drive bar 2241 is in the clamping position is smaller than the angle between the two link bars 2242 when drive bar 2241 is in the release position, so that the gap between the two jaw assemblies 222 when drive bar 2241 is in the clamping position is smaller than the gap between the two jaw assemblies 222 when drive bar 2241 is in the release position.

Specifically, in the embodiment, each of the jaw assemblies 222 includes a sliding seat 2221 and a clamping jaw 2222, the sliding seat 2221 is movably connected to the base 221 along a first predetermined direction, the clamping jaw 2222 is connected to the sliding seat 2221, and the clamping position a is formed between the clamping jaws 2222 of the two jaw assemblies 222. The elastic member 223 is connected to the two sliding seats 2221 and/or the two clamping jaws 2222. Of course, the resilient member 223 may include a plurality of members, such that the two jaw assemblies 222 are more uniformly stressed and move more smoothly. The third driving member 224 may extend between the two sliding seats 2221 by an external force to provide a driving force for moving the two sliding seats 2221 away from each other. Further, one end of each of the two connecting rods 2242 is hinged to the driving rod 2241, and the other end is hinged to the two sliding seats 2221.

Further, the fixture 22 further includes a guide rail 225 and two moving blocks 226, the guide rail 225 is connected to the base 221, the two moving blocks 226 are slidably connected to the guide rail 225, and the two sliding seats 2221 are respectively connected to the two moving blocks 226. It should be noted that the guide rail 225 extends lengthwise along a first predetermined direction. In this way, the sliding of the moving block 226 along the guide rail 225 realizes the movement of the sliding seat 2221 in the first preset direction.

Further, both ends of the guide rail 225 may be fastened to the base 221 by a threaded fastener (e.g., a bolt or a screw). The clamp 22 further includes a pressing plate 227, and two ends of the pressing plate 227 cross over corresponding ends of the guide rail 225 and are fixedly connected to the base 221, so as to tightly fix the guide rail 225 to the base 221, and effectively prevent the guide rail 225 from loosening. It should be noted that the pressing plates 227 include two pressing plates 227, and the two pressing plates 227 are respectively disposed corresponding to the opposite ends of the guide rail 225 so as to press and fix the opposite ends of the guide rail 225 to the base 221. Because in the process that anchor clamps 22 moved along with carousel 21, threaded fastener appears becoming flexible easily, leads to guide rail 225 not hard up, and the setting of clamp plate 227 can effectively avoid guide rail 225 not hard up.

In one embodiment, the base 221 has a receiving recess in which portions of the two jaw assemblies 222 are received, thereby making the clamp 22 more compact.

In one embodiment, clamp 22 further includes a guide sleeve in which drive rod 2241 is slidably disposed, the guide sleeve being disposed on base 221 to allow for more smooth movement of drive rod 2241.

In one embodiment, the two sliding seats 2221 are provided with the buffer blocks 228 at positions opposite to each other, so as to prevent an excessive impact between the two sliding seats 2221.

In one embodiment, a buffer block 228 is disposed at a position where each sliding seat 2221 is opposite to the base 221, so as to prevent an excessive impact between the sliding seat 2221 and the base 221.

It should be noted that the third driving assembly 224 of the clamp 22 of the present invention is not limited to the structure of the driving rod 2241 and the connecting rod 2242 in the above embodiment. Referring to fig. 8, in another embodiment of the present invention, third drive assembly 224 includes a drive rod 2241 and a wedge 2243. Drive bar 2241 is movably coupled to base 221 and wedge 2243 is coupled to drive bar 2241 and has two angled surfaces B facing the two jaw assemblies 222, respectively. Each inclined surface B is disposed obliquely with respect to the moving direction of the drive lever 2241. The driving rod 2241 can drive the wedge block 2243 to extend between the two jaw assemblies 222 during moving, and each jaw assembly 222 moves along the corresponding inclined surface B to depart from each other, so as to release the product at the clamping position a. Alternatively, the driving lever 2241 is movably coupled to the base 221 in a second predetermined direction perpendicular to the first predetermined direction. Further, the two inclined surfaces B of the wedge 2243 are symmetrically arranged with respect to the driving lever 2241.

In particular embodiments, the clamp 22 further includes a roller 228, and both jaw assemblies 222 are provided with the roller 228. The movement of drive bar 2241 causes roller 228 to roll along the corresponding inclined surface B, thereby causing the two jaw assemblies 222 to move away from each other. Further, the roller 228 is mounted on the two sliding seats 2221.

Please refer to fig. 1, in the embodiment of the present invention, the number of the detection stations is two, and the detection mechanism includes a short circuit detection mechanism 30a for performing short circuit detection on the product and a visual detection mechanism 30b for performing visual detection on the product. The short detection mechanism 30a is provided corresponding to one of the detection stations, and the visual detection mechanism 30b is provided corresponding to the other detection station. Thus, when the clamp 22 rotates with the turntable 21 to one of the detection stations, the short circuit detection mechanism 30a corresponding to the detection station detects a short circuit of the product on the clamp 22. When the jig 22 rotates 21 with the turntable to another inspection station, the visual inspection mechanism 30b corresponding to the inspection station performs visual inspection on the product on the jig 22 (it is understood that visual inspection refers to inspection of the appearance of the product).

Referring to fig. 1 and 9, in some embodiments, the short detection mechanism 30a includes a mounting bracket 31a and two clamping assemblies 32a connected to an external power source. The two clamping assemblies 32a are arranged on the mounting bracket 31a at intervals and are respectively used for clamping the positive electrode and the negative electrode of a product on the clamp 22 corresponding to the detection station, so that short circuit detection is performed on the product.

Further, each clamp assembly 32a further includes a clasping structure 326a mounted to the mounting bracket 325a, the clasping structure 326a being operable to clasp or release the adjustment shaft 327 a. When the clasping structure 326a clasps the adjusting shaft 327a, the adjusting shaft 327a is restricted from rotating relative to the fixed bracket 325a, so that the adjusting shaft 327a is fixed relative to the fixed bracket 325 a. The adjustment shaft 327a may be rotated relative to the fixed bracket 325a when the clasping structure 326a releases the adjustment shaft 327a, thereby adjusting the orientation of the third gripper 328 a. It should be noted that the clasping structure 326a may adopt a mature prior art, and therefore, will not be described herein.

The second gripper assembly 42 includes a second gripping position and a second release position during rotation. The second gripper assembly 42, when in the second gripping position, may grip a product positioned on the gripper 22 of the blanking station. The product may be released when the second gripper assembly 42 is in the second release position. In this way, the transfer mechanism 40 uses the rotation motion of the second grabbing component 42 to transfer the product, and compared with the linear motion in the prior art, the structure is more compact, which is beneficial to saving the occupied space. Alternatively, the rotary drive 41 may be a rotary cylinder. Preferably, the axis of rotation of the second gripper assembly 42 is parallel to the axis of rotation of the carousel 21.

Specifically, in the embodiment, the second grabbing assembly 42 includes a fourth fixing seat 421, a second telescopic driving member 422 and a second grabbing hand 423, and the second telescopic driving member 422 is mounted at the driving end of the rotary driving member 41 through the fourth fixing seat 421.

When the second gripper 423 rotates to the second gripping position, the second telescopic driving member 422 drives the second gripper 423 to extend toward the product on the jig 22 located at the blanking position to grip the product, and after the gripping is completed, the second telescopic member drives the second gripper 423 to retract so as to prevent the second gripper 423 from interfering when the second gripper 423 rotates. When the second gripper 423 rotates to the second release position, the second telescopic driving member 422 drives the second gripper 423 to extend toward the downstream device so as to release the product to the downstream device, and then the second telescopic driving member 422 drives the second gripper 423 to retract so as to prevent the second gripper 423 from interfering when the second gripper 423 rotates. Alternatively, second telescoping actuation member 422 may be a pneumatic cylinder. The second gripper 423 may adopt a structure of a gripper cylinder and a gripper, and may adopt other gripping structures, which are not limited herein.

Referring to fig. 1, in an embodiment of the present invention, the blanking device further includes a conveying mechanism 50 and a carrying mechanism 60, wherein the conveying mechanism 50 is used for receiving the products transferred and outputted by the transferring mechanism 40 and conveying the products to a carrying position along a first direction parallel to the rotation axis of the turntable 21. The conveying mechanism 60 is used for arranging the products conveyed to the conveying position by the conveying mechanism 50 on the tray.

So, conveying mechanism 50's setting makes output product stagger to lay to conveying mechanism 50's transfer mechanism 40 and the transport mechanism 60 of transport product, prevents that the two from interfering, ensures that the product circulation is quick, smooth and easy. Moreover, the conveying mechanism 50 conveys the products along the direction parallel to the rotation axis of the turntable 21, so that the transfer mechanism 40, the conveying mechanism 50 and the carrying mechanism 60 are more compact in structure, and the occupied space of the whole blanking device is saved.

Referring to fig. 1 and 11, in some embodiments, the conveying mechanism 50 includes a conveyor 51 and a product carrier 52 disposed on the conveyor 51, the product carrier 52 is used for carrying products, and the conveyor 51 is used for conveying the product carrier 52 to a carrying position along a direction parallel to the rotation axis of the turntable 21. It should be noted that the product carriers 52 may include a plurality of product carriers 52, and the product carriers 52 are disposed on the conveyor 51 at equal intervals along the conveying direction (i.e., the first direction), so as to improve the operation efficiency.

In the embodiment, the conveyor 51 is provided with guide rollers 511 on opposite sides perpendicular to the conveying direction thereof. When the product carrier 52 is conveyed along the conveying direction and passes between the guide rollers 511 at the two sides, the product carrier 52 can be matched with the guide rollers 511 at the two sides so as to guide the product carrier 52 and prevent the product carrier 52 from deviating on the conveyor. Further, the product carrier 52 is provided with a guide block 521 which can be matched with the guide rollers 511, so that the product carrier 52 can smoothly pass through the guide rollers 511 on the two sides, and the phenomenon of blocking is avoided.

In an embodiment, the product carrier 52 has a first supporting slot d and a second supporting slot e for accommodating the product, and the length dimensions of the first supporting slot d and the second supporting slot e are different, so that the product carrier 52 can be compatible with products with different length dimensions, and the compatibility of the product carrier 52 is improved.

Further, the product carrier 52 includes a fixed plate 522, two first supporting blocks 523, and two second supporting blocks 524.

Referring to fig. 12 and 13, in some embodiments, the conveying mechanism 50 further includes a product positioning assembly disposed on the conveyor 51. The product positioning assembly is located on a conveying path of the product carrier 52, i.e. between a position of the conveyor 51 for receiving the products transferred and output by the transfer mechanism 40 and a conveying position, and is used for pushing the products on the passing product carrier 52, so that the products are positioned on the product carrier 52 in the conveying direction (i.e. the first direction) to facilitate the conveying mechanism 60 to convey the products.

Specifically, in the embodiment, the product positioning assembly includes a connecting base 531, a first lifting driving member 532, a pushing sheet driving member 533 and a pushing sheet 534. The connecting base 531 is fixedly connected to the conveyor 51, the first lifting driving member 532 is installed on the connecting base 531 and above the conveyor 51, the pushing sheet driving member 533 is connected to the driving end of the first lifting driving member 532, and the pushing sheet 534 is connected to the driving end of the pushing sheet driving member 533. Thus, the first lifting/lowering driving member 532 can drive the pushing sheet driving member 533 to move in the vertical direction, and drive the pushing sheet 534 to insert into or withdraw from the first supporting slot d or the second supporting slot e. The pushing sheet driving member 533 can drive the pushing sheet to move along the conveying direction of the conveyor 51, so as to push the product in the first supporting slot d or the second supporting slot e, and make one end of the product abut against the corresponding first stopper 525 or the second stopper 526, thereby achieving the purpose of positioning the product in the conveying direction of the conveyor 51. Alternatively, the first elevation driving member 532 may be an air cylinder, and the push-piece driving member 533 may be an air cylinder.

Further, the product positioning assembly further includes a lifting plate 535, an adjusting support 536 and an adjusting member 537, wherein the first lifting driving member 532 is connected to the connecting base 531 through the lifting plate 535, and the adjusting support 536 is fixedly connected to the connecting base 531. The adjuster 537 is rotatably coupled to the adjustment support 536 and has one end threadedly coupled to the lift plate 535. Therefore, the adjusting piece 537 can be screwed to drive the lifting plate 535 to move along the conveying direction of the conveyor 51, so that the purpose of adjusting the position of the lifting plate 535 in the conveying direction of the conveyor 51 is achieved, the product positioning assembly can be compatible with products with different lengths, and the adaptability of the blanking device is enhanced.

Referring to fig. 1, 14 and 15, in an embodiment of the present invention, the carrying mechanism 60 includes a moving assembly 61 and a second carrying assembly 63 drivingly connected to the moving assembly 61. The moving assembly 61 is capable of driving the second handling assembly 63 to move along a first direction and a second direction, wherein the second direction is perpendicular to the first direction. The second handling assembly 63 can arrange the products in the handling position to the tray during the movement. Generally, the tray is provided with a plurality of placing grooves arranged in a matrix, the second carrying assembly 63 moves to the tray along the second direction after grabbing the products at the carrying position, and then moves along the first direction and/or the second direction, so that the products are arranged to the placing grooves on the tray as required. In the embodiment shown in fig. 1 and 15, the first direction is a direction perpendicular to the paper surface, and the second direction is a left-right direction.

Referring to fig. 1, 14 to 17, in an embodiment of the present invention, the blanking device further includes a tray loading and unloading mechanism 70, and the tray loading and unloading mechanism 70 includes a mounting frame 71 and a first lifting assembly 72. The mounting frame 71 has a first stacking area 711 and a second stacking area 712 for stacking trays thereon. The first lifting member 72 is disposed corresponding to the first stacking area 711, and is configured to lift and lower the trays stacked in the first stacking area 711 in the vertical direction. The conveying mechanism 60 is configured to convey the tray stacked in the second stacking area 712 to the first stacking area 711, and arrange the product at the conveying position on the tray of the first stacking area 711. Thus, the conveying mechanism 60 conveys one tray stacked in the second stacking area 712 to the first stacking area 711, and then the conveying mechanism 60 arranges the products at the conveying position on the tray. When the tray in the first stacking area 711 is full, the first lifting/lowering assembly 72 vertically lowers the tray stacked in the first stacking area 711 (generally by one tray height, so as to provide a stacking position for transporting the tray in the second stacking area 712 to the first stacking area 711 again), and then the transporting mechanism 60 transports the tray stacked in the second stacking area 712 to the first stacking area 711 again for product alignment. In this way, empty trays are stacked in the second stacking area 712, and trays full of products are stacked in the first stacking area 711, so that enough products can be accommodated in the tray loading and unloading mechanism 70, the space utilization rate is high, and the space occupied by the whole unloading device is further reduced.

In some embodiments, the first stack region 711 and the second stack region 712 are arranged in the second direction. The handling mechanism 60 further comprises a first handling assembly 62 drivingly connected to the moving assembly 61. The moving assembly 61 is also capable of driving the first handling assembly 62 to move in the second direction. The first handling assembly 62 can carry the tray in the second stacking area 712 to the first stacking area 711 during the moving process, so that the tray is transferred from the second stacking area 712 to the first stacking area 711. Therefore, the same moving assembly 61 is used for driving the first carrying assembly 62 and the second carrying assembly 63 to carry the material tray and the product respectively, the structure is simplified, and the occupied space is saved.

In particular to the embodiment, the moving assembly 61 comprises a second mount 611, a first moving structure 612, a first carriage 613 and a second moving structure 614. The first moving structure 612 is mounted on the second mounting base 611 and is in transmission connection with the first carriage 613 to drive the first carriage 613 to move along the second direction. The first handling assembly 62 and the second moving structure 614 are mounted to the first carriage 613 to move along with the first carriage 613 in the second direction. The second moving structure 614 is drivingly connected to the second handling assembly 63 for driving the second handling assembly 63 to move along the first direction. In this way, the first carrying component 62 is driven to move along the second direction to carry the material tray, and the second carrying component 63 is driven to move along the first direction and the second direction to carry the product. Alternatively, the first moving structure 612 and the second moving structure 614 may adopt a linear driving structure such as a motor-screw module, which is not limited herein.

In one embodiment, the first carrying assembly 62 includes a second lifting/lowering driving member 621, a carrying plate 622, and a suction cup 623. The second lifting drive 621 is connected to the first moving structure 612 through the first moving frame 613, and a driving end of the second lifting drive 621 is connected to the carrying plate 622 to drive the carrying plate 622 to lift in a vertical direction. Suction cups 623 are attached to the carrier plate 622 for sucking up the trays. Thus, when the trays need to be transferred, the first carrying assembly 62 moves to the second stacking area 712, the second lifting/lowering driving element 621 drives the carrying plate 622 to descend so that the suction cup 623 is close to the tray stacked in the second stacking area 712, and then sucks the tray (the tray located at the top of the second stacking area 712), and the second lifting/lowering driving element 621 drives the carrying plate 622 to ascend so as to avoid interference when moving. Then the first carrying assembly 62 moves to the first stacking area 711, the second lifting/lowering driving member 621 drives the carrying plate 622 to descend so that the tray sucked by the suction cup 623 is close to the top of the tray filled with the product in the second stacking area 712, and the suction cup 623 releases the tray so that the tray is stacked on the top of the tray filled with the product. After the tray is released, the second lifting/lowering driving member 621 drives the carrying plate 622 to ascend so as to avoid interference during movement. Alternatively, the second elevation driving part 621 may be a cylinder.

In particular embodiments, second handling assembly 63 includes a connecting plate 631 and product grasping structures for grasping and releasing products. The connecting plate 631 is drivingly connected to the moving assembly 61 to be moved in the first direction and the second direction by the moving assembly 61. The product catching structure is mounted to the connecting plate 631 to move in the first and second directions together with the connecting plate 631. More specifically, the connecting plate 631 is connected to the second moving structure 614. The product snatchs the structure and includes third lift driving piece 632 and fourth tongs 633, and third lift driving piece 632 is installed in connecting plate 631, and fourth tongs 633 is connected in the drive end of third lift driving piece 632 to drive fourth tongs 633 and go up and down in the vertical direction, so that fourth tongs 633 snatchs and releases the product. Alternatively, the third lift drive 632 may be a cylinder.

Further, the second handling assembly 63 may also include a second adjustment drive 635 and two skids 634. The two sliding plates 634 are disposed at intervals in the first direction at the connecting plate 631, and are movable in the first direction with respect to the connecting plate 631. Each sled 634 has the product grasping configuration described above mounted thereon. The second adjustment drive 635 is coupled to the two slide plates 634 to drive the two slide plates 634 toward and away from each other in a first direction to adjust the spacing of the product grasping configuration on the two slide plates 634 in the first direction. Further, the third lift drive 632 of each product gripping structure is mounted to a corresponding sled 634. As such, the two fourth grippers 633 can simultaneously grip two products and release the two products to the tray. Since the distance between two adjacent products on the conveyor may not be consistent with the distance between two adjacent product placement positions on the tray, the gap between the two sliding plates 634 can be adjusted by the second adjusting driving member 635, so that two products grabbed by the two fourth grabbers 633 can be smoothly arranged on the tray. Alternatively, the second adjuster 537 may be a cylinder. The fourth gripper 633 may adopt a structure of a gripper cylinder and a gripper, and may also adopt other gripping structures, which are not limited herein.

Specifically, in the embodiment, the first lifting assembly 72 includes a lifting base 721, a lifting driving structure 722 and a lifting support 723. The lifting seat 721 is movably connected to the mounting frame 71 along the vertical direction, and the lifting driving structure 722 is installed on the mounting frame 71 and is in transmission connection with the lifting seat 721 to drive the lifting seat 721 to lift along the vertical direction. One end of the lifting support 723 is fixedly connected to the lifting seat 721, and the other end extends into the first stacking area 711, for supporting the trays stacked in the first stacking area 711. In this way, the lifting driving structure 722 drives the lifting seat 721 to lift, so as to drive the tray supported on the lifting support 723 to lift. Alternatively, the lifting driving structure 722 may adopt a driving structure in the prior art, such as a motor screw module, which is not described herein.

More specifically, the lifting support 723 may include a plurality of (i.e., two or more) lifting support 723, and the lifting support 723 is spaced apart from each other to support the tray together, so that the tray is supported more stably, and the tray is prevented from deflecting.

In an embodiment, the tray loading and unloading mechanism 70 further includes a first feeding assembly 73 for feeding the tray stacked in the first stacking area 711 out of the first stacking area 711. When the tray in the first stacking area 711 is fully stacked, the first feeding assembly 73 can feed the tray out of the first stacking area 711. The first feeding assembly 73 includes a first tray for carrying the tray and a first feeding driving member drivingly connected to the first tray, and the first tray is movably connected to the mounting frame 71 (e.g., the first tray is movable in a first direction relative to the mounting frame 71). The first tray may enter or exit the first stacking area 711 during the movement. Thus, when the lifting support 723 of the first lifting assembly 72 is lowered to a position below the first tray, the trays (each tray is filled with products) on the lifting support 723 are supported on the first tray. Then, the first feeding driving element drives the first tray to exit the first stacking area 711, so that the operator can carry away the tray on the first tray, and at this time, the lifting and supporting element 723 can lift in the vertical direction to support the tray again. The first feeding drive then drives the first tray into the first stacking area 711 again in preparation for the next feeding. Alternatively, the first feed drive may be a pneumatic cylinder. More specifically, the first tray can be movably connected to the mounting rack 71 through the sliding block and the sliding rail, and the first feeding driving member is mounted on the mounting rack 71 and is fixedly connected to the first tray.

It should be noted that the first pallet is located in the gap between two adjacent lifting and supporting members 723, so as to avoid interference with the respective movements.

In one embodiment, the tray loading and unloading mechanism 70 further includes a lifting assembly 74, and the lifting assembly 74 includes a lifting driving member and a lifting member. The lifting driving member is disposed on the mounting frame 71, and the lifting member is connected to the lifting driving member to drive the lifting member to enter the first stacking area 711 and receive the tray conveyed by the conveying mechanism 60. Since the elevating receiver 723 cannot ascend during the process of the first tray exiting the first stacking area 711, it receives the tray conveyed to the first stacking area 711 by the conveying mechanism 60. For the uninterrupted blanking operation, the lifting assembly 74 can be used to receive the material tray conveyed by the conveying mechanism 60 during the process of the first tray exiting the first stacking area 711 at zero time, so as to ensure the uninterrupted blanking operation. When the trays (all filled with product) on the first tray completely exit the first stacking area 711, the lifting support 723 may be raised to support the trays on the lifting member, and the lifting member may be pushed out of the first stacking area 711. Preferably, the lifting assemblies 74 are disposed on opposite sides of the first stacking area 711 to provide more stable support of the tray and prevent the tray from deflecting.

In particular, in the embodiment, the tray loading and unloading mechanism 70 further includes a first positioning component for positioning the tray on the top of the trays stacked in the first stacking area 711, so as to improve the position accuracy of the conveying mechanism 60 for arranging the products to the tray. Thus, when the top tray of the trays stacked in the first stacking area 711 is filled with products, the first lifting assembly 72 lowers the height of one tray, so that the tray conveyed by the first conveying assembly 62 is released to the top of each tray stacked in the first stacking area 711, the first positioning assembly positions the top tray, and the second conveying assembly 63 is convenient to arrange the products onto the top tray.

More specifically, the first positioning assembly includes a first positioning push plate 754, a first positioning driving member 755, a first side plate 756, a second positioning push plate 751, a second positioning driving member 752 and a second side plate 753. The first positioning push plate 754 and the first side plate 756 are disposed on two sides of the first stacking area 711 in the second direction, and the second positioning push plate 751 and the second side plate 753 are disposed on two sides of the first stacking area 711 in the first direction, so that the first positioning push plate 754, the first side plate 756, the second positioning push plate 751 and the second side plate 753 surround to form the first stacking area 711. The first positioning driving member 755 is disposed on the mounting frame 71 and is in transmission connection with the first positioning pushing plate 754 to drive the first positioning pushing plate 754 to move along the second direction relative to the first side plate 756, so as to cooperate with the first side plate 756 to position the tray in the second direction. The second positioning driving member 752 is disposed on the mounting frame 71 and is in transmission connection with the second positioning pushing plate 751 to drive the second positioning pushing plate 751 to move along the first direction relative to the second side plate 753, so as to cooperate with the second side plate 753 to position the tray in the first direction.

The embodiment of the utility model provides an in, unloading mechanism 70 still includes the second lifting unit on the charging tray, and this second lifting unit sets up corresponding to second stack area 712 for along the vertical direction lift pile up in second stack area 712's charging tray. When a tray on top of each tray stacked in the second stacking area 712 is taken away by the first carrying assembly 62, the second lifting assembly drives each tray stacked in the second stacking area 712 to rise by the height of one tray, so that the tray on top can be taken away by the first carrying assembly 62. It should be noted that the second lifting assembly has a similar structure to the first lifting assembly 72, and therefore, the description thereof is omitted.

In one embodiment, the tray loading and unloading mechanism 70 further includes a second feeding assembly, which includes a second tray and a second feeding driving element. The second tray is movably connected to the mounting rack 71, and the second feeding driving member is disposed on the mounting rack 71 and is in transmission connection with the second tray to drive the second pushing tray to move. The second tray may enter or exit the second stacking area 712 during movement. Thus, when all the trays stacked in the second stacking area 712 are removed by the first handling assembly 62, the second feeding driving element drives the second tray to exit the second stacking area 712, so that the operator can stack the trays on the second tray. The second feed drive then drives the second tray into the second stacking area 712 for removal by the first handling assembly 62. It should be noted that the second feeding assembly has a similar structure to the first feeding assembly 73, and therefore, the description thereof is omitted.

In one embodiment, the tray loading and unloading mechanism 70 further includes a second positioning assembly for positioning a tray at the top of the trays stacked in the second stacking area 712, so that the first carrier assembly 62 can accurately remove the tray at the top. Moreover, when the first carrying assembly 62 takes the tray on the top of the second stacking area 712 away, the second lifting assembly drives the tray stacked in the second stacking area 712 to rise by the height of one tray, so that the tray on the top can be positioned by the second positioning assembly to prepare for the first carrying assembly 62 to take the tray on the top next time. It should be noted that the second positioning assembly and the first positioning assembly have similar structures, and therefore, are not described herein again.
