Description

TECHNICAL FIELD

[0001] The utility model relates to intelligent warehousing technical field, concretely relates to a rotary stacking machine. BACKGROUND

[0002] The fixture used for fixing the power battery in the power battery baking process (baking process) is generally large in size and heavy in weight, and the stacking machine is generally used to carry the fixture and the power battery fixed on the fixture in the power battery baking process.

[0003] The existing stacking machine generally comprises a walking device, a column device arranged on the walking device and a loading platform device connected with the column device. In actual application, when the fixture in the goods taking warehouse and the power battery fixed on the fixture are carried to the baking equipment, the walking device drives the column device and the loading platform device to move linearly along the track on the ground, and the column device drives the loading platform device to move up and down, so that the loading platform device can be moved to the position corresponding to the storage position of the goods taking warehouse. Then the fixture and the power battery fixed on the fixture can be taken out from the storage position of the goods taking warehouse by the loading platform device. Then the walking device drives the column device and the loading platform device to move linearly along the track on the ground, and the column device drives the loading platform device to move up and down, so that the loading platform device can be moved to the position corresponding to the storage position of the baking equipment. Then the fixture and the power battery fixed on the fixture can be put into the storage position of the baking equipment by the loading platform device. In this way, the fixture in the goods taking warehouse and the power battery fixed on the fixture are carried to the baking equipment. After baking, when the fixture in the baking equipment and the power battery fixed on the fixture are carried to the goods putting warehouse, the walking device drives the column device and the loading platform device to move linearly along the track on the ground, and the column device drives the loading platform device to move up and down, so that the loading platform device can be moved to the position corresponding to the storage position of the baking equipment. Then the fixture and the power battery fixed on the fixture can be taken out from the storage position of the baking equipment by the loading platform device. Then the walking device drives the column device and the loading platform device to move linearly along the track on the ground, and the column device drives the loading platform device to move up and down, so that the loading platform device can be moved to the position corresponding to the storage position of the goods putting warehouse. Then the fixture and the power battery fixed on the fixture can be put into the storage position of the goods putting warehouse by the loading platform device. In this way, the fixture in the baking equipment and the power battery fixed on the fixture are carried to the goods putting warehouse.

[0004] Since linear movement along the track on the ground is required, the space occupied by the stacking machine is relatively large, the space utilization rate is low, the area of the factory building is increased, and the production cost is increased. SUMMARY

[0005] To overcome the shortcomings of existing technologies, this utility model provides a rotary stacker that occupies little space, improves space utilization, reduces factory area, and reduces production costs.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A rotary stacker includes a column assembly and a loading platform assembly connected to the column assembly, and a rotating device. The column assembly is mounted on the rotating device. The rotating device includes a rotating base, a rotating base plate, and a rotating drive mechanism. The rotating drive mechanism is located at the top of the rotating base, and the rotating base plate is located at the top of the rotating drive mechanism. The rotating drive mechanism drives the rotating base plate to rotate. The column assembly includes a column and a lifting drive mechanism mounted on the column. The column is located at the top of the rotating base plate. The loading platform assembly includes a loading platform and a fork mechanism mounted on the loading platform. One end of the loading platform is connected to the column, and the other end of the loading platform extends away from the column. The lifting drive mechanism drives the loading platform to move up and down.

[0008] The beneficial effects of this utility model are as follows: This utility model uses a rotating device, which includes a rotating base, a rotating bottom plate, and a rotating drive mechanism. The rotating drive mechanism and the rotating bottom plate drive the column device and the loading platform device to rotate. The column device drives the loading platform device to move up and down, thereby enabling the loading platform device to be moved to a position corresponding to the picking warehouse, the baking equipment warehouse, or the placing warehouse. By using a rotating device instead of a walking device, there is no need to move in a straight line along a track on the ground. This reduces the space occupied, improves space utilization, reduces the factory area, and reduces production costs. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions.

[0035] Please refer to Figure 1 and Figure 2 An embodiment of the present invention provides a rotary stacker, including a rotating device 10, a column device 20 disposed on the rotating device 10, and a loading platform device 30 connected to the column device 20.

[0036] Specifically, in combination Figures 3 to 6 As shown, the rotating device 10 includes a rotating base 111, a rotating base plate 112, and a rotating drive mechanism. The rotating base 111 is mounted on the ground. The rotating drive mechanism is located at the top of the rotating base 111. The rotating base plate 112 is located at the top of the rotating drive mechanism 111, and the rotating drive mechanism is used to drive the rotating base plate 112 to rotate.

[0037] In this embodiment, the rotary drive mechanism includes a slewing bearing 1131 (i.e., a slewing support), a drive gear 1132, and a rotary motor 1133. The inner ring (toothless) of the slewing bearing 1131 is located at the top of the rotating base 111, and the rotating base plate 112 is located at the top of the outer ring 11311 (toothed) of the slewing bearing 1131. The slewing bearing 1131 is a conventional structure, and its structure will not be described in detail here. The drive gear 1132 is located around the slewing bearing 1131. The drive gear 1132 is sleeved on the outer circumference of the drive shaft 1134 and meshes with the outer ring 11311 of the slewing bearing 1131. One end of the drive shaft 1134 is rotatably mounted on the top of the rotating base 111, and the other end of the drive shaft 1134 extends upward and is connected to the output end of the rotary motor 1133. The rotary motor 1133 is mounted on the top of the rotating base 111 through a motor mount. The rotary motor 1133 is used to drive the drive shaft 1134 to rotate, which in turn drives the drive gear 1132 to rotate, which in turn drives the outer ring 11311 of the slewing bearing 1131 to rotate, which in turn drives the rotating base plate 112 to rotate. The slewing bearing 1131 can simultaneously withstand large axial and radial loads and overturning moments. It features high precision, strong load-bearing capacity, and smooth operation. The transmission is achieved by using the drive gear 1132 and the slewing bearing 1131, resulting in high transmission precision. This improves the stability and precision of the rotation of the rotating base plate 112, thereby improving the stability and precision of the rotation of the loading platform device 30. In turn, it improves the stability and precision of the pick-and-place clamp 100 and the power battery fixed on the clamp 100.

[0038] In this embodiment, the top of the rotating base 111 is provided with a base mounting hole, which is located on the periphery of the slewing bearing 1131. One end of the drive shaft 1134 is rotatably mounted in the base mounting hole via a slewing bearing, etc. The rotating base plate 112 protrudes from the outer circumferential surface of the outer ring 11311 of the slewing bearing 11311. The top of the rotating base 111 is provided with an annular slewing bearing protective cover 11312, which is arranged around the outer circumference of the outer ring 11311 of the slewing bearing 11311 and located below the rotating base plate 112. The slewing bearing protective cover 11312 has a clearance hole for avoiding the drive gear 1132. The slewing bearing protective cover 11312 provides protection for the slewing bearing 1131. The drive gear 1132 is housed within the drive gear protective cover 11321, which is located at the top of the rotating base 111. The bottom and top of the drive gear protective cover 11321 are respectively provided with a first clearance hole and a second clearance hole for avoiding one end and the other end of the drive shaft 1134. The drive gear protective cover 11321 has an opening on the side near the slewing bearing 1131, which facilitates the meshing of the drive gear 1132 with the outer ring 11311 of the slewing bearing 1131. The drive gear protective cover 11321 provides protection for the drive gear 1132.

[0039] Furthermore, the rotating device 10 also includes a barcode positioning mechanism 13, which includes an annular barcode strip (not shown in the figure) and a barcode scanner 131. An annular barcode backplate 1121 is provided at the top of the rotating base plate 112. The barcode backplate 1121 is close to the outer peripheral surface of the rotating base plate 112, and the center of the barcode backplate 1121 and the center of the rotating base plate 112 are located on the same vertical line. The barcode strip is attached to the outer peripheral surface of the barcode backplate 1121 by adhesive bonding. Multiple barcodes are spaced circumferentially on the barcode strip. The number of barcodes can be set according to actual conditions. The barcode scanner 131 is located on the periphery of the rotating base plate 112 and is mounted on the top of the rotating base 111 via a barcode scanner bracket 1311. The positions of the barcode scanner 131 and the barcode scanner bracket 1311 on the rotating base 111 can be set according to actual conditions. The barcode scanner 131 is opposite to the barcode strip and is used to read the barcodes on the barcode strip. The rotation of the base plate 112 can drive the barcode back plate 1121 to rotate, thereby driving the barcode strip and multiple barcodes to rotate. Each barcode corresponds to an angle. If, in the initial position, the scanner 131 corresponds to the first barcode, when the rotating base plate 112 needs to be rotated, for example, clockwise to a predetermined angle, the rotating base plate 112, the barcode strip, and multiple barcodes are first driven to rotate, for example, clockwise, by the rotating motor 1133. When the scanner 131 reads the barcode corresponding to the predetermined angle, it indicates that the rotating base plate 112 has rotated to the predetermined angle. At this time, the scanner 131 outputs a signal to the control system, which then controls the rotating motor 1133 to stop working, thereby stopping the rotating base plate 112 from rotating. Thus, the rotating base plate 112 accurately stops at the predetermined angle. This allows for precise control of the rotation angle of the rotating base plate 112, thereby enabling precise control of the rotation angle of the loading platform device 30, ensuring that the position of the loading platform device 30 does not deviate, and improving the accuracy of picking up and placing the clamp 100 and the power battery fixed on the clamp 100.

[0040] Furthermore, the rotating device 10 also includes a braking mechanism 15, which is used to clamp the rotating base plate 111 after it stops rotating. Because there is a gear gap between the drive gear 1132 and the outer ring 11311 of the slewing bearing 1131, the rotating base plate 112 usually shakes after the rotating motor 1133 stops working, causing the column device 20 and the loading platform device 30 to shake. By clamping the rotating base plate 112 after it stops rotating using the braking mechanism 15, shaking of the rotating base plate 112, column device 20, and loading platform device 30 can be avoided, improving the stability of the loading platform device 30 in picking up and placing the clamp 100 and the power battery fixed on the clamp 100. In this embodiment, there are two braking mechanisms 15, with the rotating motor 1133 located between the two braking mechanisms 15. Understandably, the number of braking mechanisms 15 can be set according to actual conditions.

[0041] Specifically, the braking mechanism 15 includes a brake base 151 located around the rotating base plate 112, a brake drive component 152, and two brake grippers 153 arranged vertically opposite each other. The brake base 151 is located at the top of the rotating base 111. In this embodiment, the top of the rotating base 111 has a mounting groove, and the brake base 151 is located at the bottom of the mounting groove. One end of the brake base 151 extends away from the rotating base plate 112, and the other end of the brake base 151 is close to the rotating base plate 112. The brake drive component 152 is located at the top of the brake base 151 via a drive component mounting plate 1521 and is close to one end of the brake base 151. The brake base 151 has two opposing brake mounting plates 1511 at its top end, which are close to the other end of the brake base 151. Two brake chucks 153 are located between the two brake mounting plates 1511 and are hinged together by a hinge shaft 154. The hinge shaft 154 is rotatably positioned between the two brake mounting plates 1511. In this embodiment, two mounting holes are provided on the side of the two brake mounting plates 1511 that are close to each other. The two ends of the hinge shaft 154 are rotatably positioned in the two mounting holes and protrude from the side of the two brake mounting plates 1511 that are far apart from each other. The mounting ends of the two brake chucks 153 are connected to the output end of the brake drive component 152 through two hinges 155. The clamping ends of the two brake pawls 153 are located on the outside of the barcode back plate 1121 and above and below the rotating base plate 112, respectively. The brake drive unit 152 is used to drive the two hinges 155 to move towards or away from the rotating base plate 112, thereby causing the mounting ends of the two brake pawls 153 to move away from or towards each other, and further causing the clamping ends of the two brake pawls 153 to move towards or away from each other, so as to clamp or release the rotating base plate 112. In practical applications, after the rotating base plate 112 stops rotating, the brake drive component 152 drives the two hinges 155 to move towards the rotating base plate 112, thereby causing the mounting ends of the two brake pawls 153 to move away from each other, and then causing the clamping ends of the two brake pawls 153 to move closer to each other to clamp the rotating base plate 112. When the rotating base plate 112 needs to rotate, the brake drive component 152 first drives the two hinges 155 to move away from the rotating base plate 112, thereby causing the mounting ends of the two brake pawls 153 to move closer to each other, and then causing the clamping ends of the two brake pawls 153 to move away from each other to release the rotating base plate 112. Then, the rotating motor 1133 can drive the rotating base plate 112 to rotate.

[0042] In this embodiment, the brake drive component 152 is a cylinder. It can be understood that the brake drive component 152 can also be other components, such as a hydraulic cylinder, or a linear module. Two brake baffles 1513 are provided between the two brake mounting plates 1511 and the drive component mounting plate 1521. The two brake baffles 1513 are respectively set at the top of the brake base 151. The hinge shaft 154, the two hinges 155, the output end of the brake drive component 152, and the two brake pawls 153 are partially housed in the brake protective cover 1512. The bottom end and the end near the rotating base plate 112 of the brake protective cover 1512 are open. The brake protective cover 1512 is set on the two brake baffles 1513 and the two brake mounting plates 1511. The brake protective cover 1512 can protect the hinge shaft 154, the two hinges 155, and the two brake pawls 153. The top and bottom of the rotating base plate 112 are respectively provided with two annular brake pads 1122. The barcode back plate 1121 is located inside the brake pads 1122. The brake pads 1122 correspond to the clamping ends of the brake pawls 153, and the outer circumferential surface of the brake pads 1122 is flush with the outer circumferential surface of the rotating base plate 112. Two brake buffer pads 1531 are respectively provided on the side where the clamping ends of the two brake pawls 153 are close to each other. The two brake buffer pads 1531 correspond to the two brake pads 1122. The brake pads 1122 and the brake buffer pads 1531 are made of the same material, such as rubber or silicone. The two brake pads 1122 and the two brake buffer pads 1531 play a buffering role and can prevent damage to the rotating base plate 112.

[0043] Combination Figures 7 to 14 As shown, the column device 20 includes a column 21 and a lifting drive mechanism 23 mounted on the column 21. The column 21 is located at the top of the rotating base plate 112 and inside the barcode back plate 1121. The rotation of the rotating base plate 112 can drive the column 21 and the lifting drive mechanism 23 to rotate.

[0044] The loading platform device 30 includes a loading platform 31 and a fork mechanism mounted on the loading platform 31. One end of the loading platform 31 is connected to a column 21, and the other end of the loading platform 31 extends away from the column 21. A lifting drive mechanism 23 is used to drive the loading platform 31 to move up and down, thereby driving the fork mechanism to move up and down. The rotation of the column 21 can drive the loading platform 31 and the fork mechanism to rotate. In this embodiment, a support frame 311 is provided at one end of the loading platform 31, and two connecting frames 312 are provided on the support frame 311. The column 21 is located between the two connecting frames 312. Two column guide rail assemblies are provided on both sides of the column 21, and the two column guide rail assemblies correspond to the two connecting frames 312 respectively. Guide wheel assemblies are provided on the connecting frames 312, and the guide wheel assemblies on the two connecting frames 312 are respectively rolledly connected to the corresponding column guide rail assemblies. The use of guide wheel assemblies and column guide rail assemblies can improve the stability of the loading platform 31's up and down movement.

[0045] The column guide rail assembly includes a first column guide rail 212a and a second column guide rail 212b arranged side by side. The length direction of the first column guide rail 212a and the second column guide rail 212b is the same as the height direction of the column 21. The center line of the height direction of the column 21 is located between the first column guide rail 212a and the second column guide rail 212b. The first column guide rail 212a is close to the loading platform 31. The guide wheel assembly includes, for example, four first guide wheels 313 and several second guide wheels 314. The four first guide wheels 313 are arranged in pairs at vertical intervals. Two of the vertically spaced first guide wheels 313 are rolledly connected to the outer side of the first column guide rail 212a of the corresponding column guide rail assembly. The other two vertically spaced first guide wheels 313 are rolledly connected to the outer side of the second column guide rail 212b of the corresponding column guide rail assembly. The outer side of the first column guide rail 212a and the outer side of the second column guide rail 212b refer to the side of the first column guide rail 212a and the second column guide rail 212b that are far apart from each other. Four second guide wheels 314 are located between four first guide wheels 313. The four second guide wheels 314 are arranged in pairs at vertical intervals. Two of the vertically spaced second guide wheels 314 are rolledly connected to the end of the first column guide rail 212a away from the column 21, and the other two vertically spaced second guide wheels 314 are rolledly connected to the end of the second column guide rail 212b away from the column 21. Understandably, the number of first guide wheels 313, second guide wheels 314, and column guide rails can be set according to actual conditions.

[0046] The lifting drive mechanism 23 includes a lifting motor 231, which is mounted on the end of the column 21 away from the loading platform 31 via a motor base. Two drums are respectively installed at the two output ends of the lifting motor 231, and steel wire ropes 232 are wound on the drums. Two pulley groups are respectively provided on both sides of the column 21 near its top. The ends of the steel wire ropes 232 on the two drums pass over the two pulley groups and are respectively connected to two overload slack rope assemblies 315. The two overload slack rope assemblies 315 are respectively mounted on the support frame 311 and are spaced apart along the width direction of the loading platform 31. Two safety clamps 317 are provided on the support frame 311. The two safety clamps 317 are located between the two overload slack rope assemblies 315 and are spaced apart vertically. The two safety clamps 317 are connected to the two overload slack rope assemblies 315 through a brake linkage assembly 316. It can be understood that the number of safety clamps 317 can be set according to the actual situation, such as one or three. A T-shaped brake guide rail 213 is provided at one end of the column 21 near the loading platform 31. The length direction of the brake guide rail 213 is the same as the height direction of the column 21. The brake guide rail 213 cooperates with two safety clamps 317, which are used to clamp the brake guide rail 213. The lifting motor 231 drives the two drums to rotate, thereby moving the loading platform 31 up and down through the corresponding wire rope 232, two overload slack rope assemblies 315, brake linkage assembly 316, and two safety clamps 317. In this embodiment, the drums are housed in a drum protective cover 233, which is mounted on the motor base and protects the drums. The pulley block includes two pulleys 211 arranged side by side. Understandably, the number of pulleys 211 can be set according to the actual situation.

A sleeve 3151 is provided at the bottom end of the first support plate 3111a and is sleeved on the outer periphery of the pull rod 3152. The pull rod 3152 can move up and down relative to the sleeve 3151 and the first support plate 3111a. The bottom end of the pull rod 3152 protrudes from the bottom end of the sleeve 3151, and the top end of the pull rod 3152 protrudes from the top end of the first support plate 3111a and is connected to the wire rope collar 3155. The ends of the wire ropes 232 on the two drums are respectively wound around the wire rope collars 3155 of the two overload slack rope assemblies 315, and the ends of the wire ropes 232 are locked to the wire ropes 232 by the wire rope lock 3156. The outer periphery of the pull rod 3152 is threadedly connected to a limiting element 3153, such as a nut, which abuts against the bottom end of the sleeve 3151. A spring 3154 is disposed inside the sleeve 3151 and within the through hole of the first support plate 3111a, and is sleeved on the outer periphery of the pull rod 3152. One end of the spring 3154 is connected to the inner wall of the sleeve 3151, and the other end of the spring 3154 protrudes from the top end of the first support plate 3111a and is connected to the outer wall of the pull rod 3152.

[0048] The safety clamp 317 mainly includes an outer shell 3171, an inner shell 3172, two opposing inclined blocks 3173, two opposing brake wedges 3174, a first brake connecting block 3175, a moving rod 3176, and a lifting plate 3177. A second support plate 3111b is located above the first support plate 3111a between the inner walls of both ends of the support frame 311. The outer shells 3171 of the two safety clamps 317 are respectively located at the bottom ends of the first support plate 3111a and the second support plate 3111b. The inner shell 3172 is located inside the outer shell 3171. The side of the outer shell 3171 away from the loading platform 31 and the side of the inner shell 3172 away from the loading platform 31 are respectively open. The two inclined blocks 3173 are inclined towards each other and located at the openings of the inner shell 3172, and are respectively located on the inner walls at both ends of the inner shell 3172. Two brake wedges 3174 are located between two inclined blocks 3173. Each of the two brake wedges 3174 has a slope on its far side, and the slopes of the two brake wedges 3174 respectively mate with the close sides of the two inclined blocks 3173. A brake guide rail 213 passes between the two brake wedges 3174 of the two safety clamps 317. The top of the outer shell 3171 has a clearance groove for avoiding the brake guide rail 213. A first brake connecting block 3175 is located between the two brake wedges 3174 and the inner wall of the inner shell 3172 near the loading platform 31. The first brake connecting block 3175 has two strip-shaped holes corresponding to the two brake wedges 3174. The length direction of the strip-shaped holes is the same as the width direction along the loading platform 31. Each of the two brake wedges 3174 has two wedge mounting holes corresponding to the two strip-shaped holes on its side near the loading platform 31. Fasteners are installed in the wedge mounting holes. Component 31741, such as a pin, has one end passing through the corresponding strip hole and located between the inner wall of the first brake connecting block 3175 and the inner shell 3172 near the loading platform 31. A limiting piece is sleeved on the outer periphery of one end of the fastener 31741. The outer diameter of the limiting piece is larger than the width of the strip hole. The limiting piece contacts the side of the first brake connecting block 3175 near the loading platform 31. The limiting piece can prevent the fastener 31741 from disengaging from the corresponding strip hole. The top of the outer casing 3171 is provided with a second brake connecting block 3178, and the moving rod 3176 is located on the side of the first brake connecting block 3175 near the loading platform 31. The top of the moving rod 3176 passes through the hole in the outer casing 317 and the hole in the lifting plate 3177 and is located above the lifting plate 3177. The moving rod 3176 and the lifting plate 3177 are relatively fixed. The second brake connecting block 3178 has a clearance hole for avoiding the moving rod 3176.Two inclined guide plates 31731 are provided on both sides of the inclined block 3173. One end of the guide plate 31731 is provided with a guide part. Two guide grooves are provided on both sides of the brake wedge 3174. The two guide grooves slide in cooperation with the guide parts of the two guide plates 31731 of the corresponding inclined block 3173. The guide plates 31731 play a guiding role in the up and down movement of the corresponding brake wedge 3174, which can improve the stability of the up and down movement of the brake wedge 3174.

[0049] The brake linkage assembly 316 includes two V-shaped first linkages 3161, two second linkages 3162, two third linkages 3163, and two fourth linkages 3164. The two first linkages 3161, two second linkages 3162, two third linkages 3163, and two fourth linkages 3164 are symmetrically arranged about the center of the support frame 311. One end of the first linkage 3161 has a slotted hole 31611. A cam follower (not shown in the figure) is provided on the pull rod 3152. The cam followers of the pull rods 3152 of the two overload slack rope assemblies 315 respectively cooperate with the slotted holes 31611 of the two first linkages 3161. A portion of the first linkage 3161 extends between the second brake connecting block 3178 and the lifting plate 3177 located below the safety clamp 317 and abuts against the bottom end of the lifting plate 3177. The first link 3161 is rotatably connected at its V-angle to the side of the first support plate 3111a away from the loading platform 31 via a first link pivot 31612. Two safety clamps 317 are located between the two second links 3162 and the two third links 3163. One end of each of the two second links 3162 is rotatably connected to the two first links 3161 via two second link pivots 31621, and the other end of each of the two second links 3162 is connected to one end of each of the two third links 3163 via two connecting rods. The other ends of each of the two third links 3163 are rotatably connected to the two fourth links 3164 via two third link pivots 31631. One end of each of the two fourth links 3164 is rotatably connected to the side of the second support plate 3111b away from the loading platform 31 via two fourth link pivots 31641. The two fourth links 3164 extend into the space between the second brake connecting block 3178 and the lifting plate 3177 of the safety clamp 317 located above, and abut against the bottom end of the lifting plate 3177.

[0050] The two safety clamps 317 and two overload slack rope assemblies 315 prevent the loading platform 31 from moving downwards due to the breakage of the wire rope 232, ensuring safety during use. In actual application, in the initial state, one end of the fastener 31741 installed on the two brake wedges 3174 is located in the two far apart ends of the strip holes. The springs 3154 of the two overload slack rope assemblies 315 are in a stretched state. When the wire rope 232 breaks, under the reset action of the springs 3154 of the two overload slack rope assemblies 3155, the corresponding pull rod 3152 can be moved downwards through the springs 3154. Thus, the cam follower of the two overload slack rope assemblies 315 can drive one end of the two first connecting rods 3161 to move downwards. Under the action of the first link shaft 31612, the portion of the first link 3161 that extends into the space between the second brake connecting block 3178 and the lifting plate 3177 of the lower safety clamp 317 can move upward, as can the two second links 3162. This causes the lifting plate 3177 of the lower safety clamp 317 to move upward. The upward movement of the two second links 3162 causes the two third links 3163 to move upward, which in turn causes the portion of the two fourth links 3164 that extends into the space between the second brake connecting block 3178 and the lifting plate 3177 of the upper safety clamp 317 to move upward, which in turn causes the lifting plate 3177 of the upper safety clamp 317 to move upward. The upward movement of the lifting plate 3177 of the safety clamp 317 can drive the moving rod 3176 to move upward, thereby driving the first brake connecting block 3175 to move upward, which in turn can drive the two brake wedges 3174 to move upward. During the upward movement of the two brake wedges 3174, the distance between the sides of the two brake wedges 3174 that are close to each other gradually decreases. In this way, the two brake wedges 3174 can clamp the brake guide rail 213, thereby stopping the loading platform 31 from moving downward.

[0051] Combination Figure 12 , Figure 13 , Figures 15 to 17As shown, the forklift mechanism includes a docking platform assembly 33 mounted on the loading platform 31, a pick-and-place assembly 35 mounted on the docking platform assembly 33, a door opening assembly 37 mounted on the loading platform 31, and a positioning locking assembly 39 mounted on the docking platform assembly 33. The docking platform assembly 33 is used to dock with the loading and unloading compartments of the picking compartment, the baking equipment, and the unloading compartment. The pick-and-place assembly 35 is used to drag the clamps 100 located in the compartment and the power batteries fixed on the clamps 100 onto the docking platform assembly 33, and to push the clamps 100 located on the docking platform assembly 33 and the power batteries fixed on the clamps 100 into the compartment. By using the docking platform assembly 33 and the pick-and-place assembly 35, when picking and placing the clamps 100 and the power batteries fixed on the clamps 100 in the compartment of the baking equipment, it is not necessary to reach into the compartment of the baking equipment for picking and placing, which will not damage the heating components in the compartment of the baking equipment, etc., and reduce production costs. The door opening assembly 37 is used to open and close the doors of the picking and placing warehouses, eliminating the need for manual operation and improving production efficiency. The positioning locking assembly 39 is used to lock the clamp 100 onto the connecting platform assembly 33 to prevent the clamp 100 from moving and to avoid the clamp 100 and the power battery fixed to the clamp 100 from falling off.

[0052] The docking platform assembly 33 includes a docking platform 331 and a docking linear module 332. The bottom end of the docking platform 331 is slidably connected to the top end of the loading platform 31 via a conventional slide rail and a slider that slidably engages with the slide rail.

The two support members 3311 are arranged opposite to each other, and the top end of the support member 3311 is provided with a docking guide rail 3312. The top of the loading platform 31 is provided with a first mounting position 318, which is located near the side of the loading platform 31. A connecting linear module 332 is located at the bottom of the first mounting position 318 and connected to the bottom of the connecting platform 331. The connecting linear module 332 drives the connecting platform 331 to move horizontally back and forth along the length of the loading platform 31, thereby driving the two support members 3311 and the connecting guide rails 3312 of the two support members 3311 to move horizontally back and forth along the length of the loading platform 31. The connecting guide rails 3312 of the two support members 3311 are used to roll in cooperation with the two rows of rollers 102 on both sides of the bottom end of the clamp 100. Figure 9 As shown.

[0053] In this embodiment, the bottom of the first mounting position 318 is provided with a plurality of first mounting beams 3181 spaced apart along the length of the loading platform 31. The top of the first mounting beams 3181 is provided with a first mounting plate 3182. The connecting linear module 332 is disposed on the top of the first mounting plate 3182 of the plurality of first mounting beams 3181. The number of first mounting beams 3181 can be set according to the actual situation. Two stops 33121 are formed on both sides of the top of one of the connecting guide rails 3312. The two stops 33121 are arranged opposite to each other, and the two stops 33121 and the connecting guide rail 3312 form a U-shaped structure. In actual application, when the two rows of rollers 102 at the bottom of the clamp 100 roll on the connecting guide rails 3312 of the two support members 3311 respectively, the two stops 33121 can limit the corresponding row of rollers 102, which can prevent the two rows of rollers 102 at the bottom of the clamp 100 from disengaging from the corresponding connecting guide rails 3312.

[0054] The pick-and-place assembly 35 includes a pick-and-place base plate 351, a pick-and-place linear module 355, two opposing grippers 352, and a gripper drive module.

The gripping hooks 352 have gripping hook grooves 3521, and the gripping hook grooves 3521 of the two gripping hooks 352 are arranged opposite each other and are respectively used to engage with the two protrusions 101 of the clamp 100 (see Figure 9The two pick-and-place bases 353 are slidably mounted on the top of the pick-and-place base plate 351 via conventional slide rails and sliders that slidably engage with the slide rails. A hook drive module is located at the top of the pick-and-place base plate 351 and between the two pick-and-place bases 353. The two pick-and-place bases 353 are connected to the hook drive module, which drives the two pick-and-place bases 353 to move closer or further apart, thereby causing the two hooks 352 to move closer or further apart, so that the hook grooves 3521 of the two hooks 352 engage or disengage with the two protrusions 101 of the clamp 100. Movement of the connecting platform 331 drives the pick-and-place assembly 35 to move synchronously.

[0055] In this embodiment, the grab hook drive module includes a pick-and-place motor 3541, a pick-and-place reducer 3542, a pick-and-place shaft 35431, a pick-and-place gear 3543, and two racks 3544. The pick-and-place reducer 3542 is mounted on the top of the pick-and-place base plate 351 via a reducer base 35421, and the pick-and-place motor 3541 is mounted on the pick-and-place reducer 3542.

One end of the two racks 3544 is flush with the other end of the two pick-and-place connecting plates 3545. The pick-and-place motor 3541 drives the pick-and-place gear 3543 to rotate via the pick-and-place reducer 3542, thereby causing the two racks 3544 to move towards each other or away from each other. This, in turn, via the two pick-and-place connecting plates 3545, causes the two pick-and-place bases 353 to move closer or further apart. In this embodiment, the two racks 3544 are respectively housed within two rack protective covers 3546, which are respectively positioned on the side of the two pick-and-place connecting plates 3545 that are close to each other.

The push-pull electromagnet 392 has an existing structure, which will not be described in detail here. When energized, the push-pull electromagnet 392 pushes the guide shaft 393 upwards; when de-energized, it stops pushing the guide shaft 393 upwards. When energized again, it pushes the guide shaft 393 downwards; when de-energized again, it stops pushing the guide shaft 393 downwards. This process is repeated to achieve the up-and-down movement of the guide shaft 393. A linear bearing 3913 is installed in the through hole of the locking mounting base 3912. The linear bearing 3913 is sleeved on the outer circumference of the guide shaft 393, guiding the up-and-down movement of the guide shaft 393 and improving its stability. The movement of the connecting platform 331 causes the locking assembly 39 to move synchronously. In this embodiment, the number of positioning locking components 39 corresponds to the number of connecting holes of the clamp 100. There are two connecting holes at the bottom of the clamp 100, so there are also two positioning locking components 39. The two positioning locking components 39 are symmetrically arranged about the center of the docking platform 331. When the clamp 100 is located at the top of the docking guide rail 3312 of the two support members 3311 of the docking platform 331, the guide shaft 393 of the two positioning locking components 39 corresponds to the two connecting holes at the bottom of the clamp 100.

The multiple ceiling rail guide wheels 217 are distributed in a ring at intervals around the annular guide rail 61 and are respectively in rolling contact with the outer peripheral surface of the annular guide rail 61. The number of ceiling rail guide wheels 217 can be set according to the actual situation. The rotation of the column 21 can drive the ceiling rail connecting seat 214, the ceiling rail connecting shaft 215, and the multiple ceiling rail guide wheels 217 to rotate around the axis of the ceiling rail 60. The ceiling rail 60, ceiling rail connecting seat 214, ceiling rail connecting shaft 215, and multiple ceiling rail guide wheels 217 can provide support for the rotation of the column 21, thereby improving the stability of the column 21.

[0063] In practical application, when the clamp 100 in the picking compartment and the power battery fixed on the clamp 100 are transported to the baking equipment, the loading platform 31 and the fork mechanism are first driven to rotate clockwise by the rotary drive mechanism, and the loading platform 31 and the fork mechanism are driven to move up and down by the lifting drive mechanism 22 so that the fork mechanism corresponds to the position of the picking compartment. At this time, the unlocking groove 3722 of the unlocking plate 372 corresponds to the cam follower at the bottom of the door of the picking compartment, and the connecting platform 331 corresponds to the position of the picking compartment. Then, the door-opening linear module 373 drives the unlocking plate 372 to move towards the compartment near the picking compartment, so that the unlocking groove 3722 of the unlocking plate 372 engages with the cam follower of the picking compartment. Then, the rotary drive mechanism drives the loading platform 31 and the fork mechanism to continue rotating clockwise. Driven by the unlocking plate 372, the compartment door of the picking compartment can be opened. Then, the door-opening linear module 373 drives the unlocking plate 372 to move towards the column 21 back to its initial position, so that the unlocking groove 3722 of the unlocking plate 372 separates from the cam follower of the picking compartment. Then, the rotary drive mechanism drives the loading platform 31 and the fork mechanism to rotate counterclockwise, so that the fork mechanism returns to the position corresponding to the picking compartment. Then, the connecting linear module 332 drives the connecting platform 331 to move towards the compartment near the picking-up warehouse, so that the connecting platform 331 docks with the compartment of the picking-up warehouse. At this time, the two rows of rollers 102 on both sides of the bottom end of the clamp 100 of the picking-up warehouse correspond to the connecting guide rails 3312 of the two support members 3311 of the connecting platform 331. Then, the hook driving module drives the two hooks 352 to move away from each other until the two hooks 352 protrude from both ends of the picking-up base plate 351, as shown. Figure 15 and Figure 16As shown, the pick-and-place linear module 355 drives the pick-and-place base plate 351, the two grippers 352, and the gripper drive module to move towards the compartment near the pick-and-place compartment until the clamp 100 in the compartment of the pick-and-place compartment is located between the two grippers 352 and the gripper grooves 3521 of the two grippers 352 correspond to the two protrusions 101 of the clamp 100 respectively. Then, the gripper drive module drives the two grippers 352 to move closer to each other so that the gripper grooves 3521 of the two grippers 352 cooperate with the two protrusions 101 of the clamp 100 respectively. Then, the pick-and-place linear module 355 drives the pick-and-place base plate 351, the two grippers 352, and the gripper drive module to move towards the column 21. Thus, the two grippers 352 can drive the clamp 100 and the power battery fixed on the clamp 100 to move towards the column 21. During the movement of the clamp 100, the two rows of rollers 101 on both sides of the bottom end of the clamp 100 can roll on the connecting guide rails 3312 of the two support members 3311 respectively, until the two rows of rollers 101 at the bottom end of the clamp 100 are respectively on the connecting guide rails 3312 of the two support members 3311. At this time, the pick-and-place base plate 351, the two grippers 352, and the gripper drive module return to the initial position. In this way, the clamp 100 and the power battery fixed on the clamp 100 in the pick-and-place compartment are dragged by the pick-and-place component 35 onto the connecting platform component 33. Then, the guide shaft 393 is driven upward by the push-pull electromagnet 392 so that the other end of the guide shaft 393 engages with the connecting hole at the bottom of the clamp 100, thereby locking the clamp 100 onto the docking platform assembly 33. Then, the two hooks 352 are driven away from each other by the hook drive module so that the hook grooves 3521 of the two hooks 352 are separated from the two protrusions 101 of the clamp 100. Then, the docking linear module 332 drives the docking platform 331, the clamp 100, and the power battery fixed on the clamp 100 to move towards the column 21 to the initial position. Then, the rotary drive mechanism drives the loading platform 31, the fork mechanism, the clamp 100, and the power battery fixed on the clamp 100 to rotate clockwise so that the unlocking groove 3722 of the unlocking plate 372 aligns with the cam follower of the loading compartment position. Then, the door opening linear module 373 drives the unlocking plate 372 to move towards the cam follower of the pickup compartment, so that the unlocking groove 3722 of the unlocking plate 372 engages with the cam follower of the pickup compartment. Then, the rotary drive mechanism drives the loading platform 31, fork mechanism, clamp 100, and power battery fixed on the clamp 100 to rotate counterclockwise, thereby closing the pickup compartment door under the action of the unlocking plate 372. Then, the door opening linear module 373 drives the unlocking plate 372 to move towards the column 21 to its initial position, so that the unlocking groove 3722 of the unlocking plate 372 separates from the cam follower of the pickup compartment.

[0064] Then, the loading platform 31 and fork mechanism are driven to rotate clockwise via a rotary drive mechanism, and the loading platform 31 and fork mechanism are driven to move up and down via a lifting drive mechanism 22, so that the fork mechanism aligns with the compartment of the baking equipment. Then, the connecting linear module 332 drives the connecting platform 331 to move towards the compartment of the baking equipment, so that the connecting platform 331 docks with the compartment of the baking equipment. Then, the hook drive module drives the two hooks 352 to move closer to each other, so that the hook grooves 3521 of the two hooks 352 respectively engage with the two protrusions 101 of the clamp 100. Then, the push-pull electromagnet 392 drives the guide shaft 393 to move downward, so that the other end of the guide shaft 393 separates from the connecting hole at the bottom of the clamp 100. Then, the pick-and-place linear module 355 drives the pick-and-place base plate 351, two grippers 352, gripper drive module, and clamp 100 to move towards the compartment of the baking equipment, so that the clamp 100 is pushed into the compartment of the baking equipment by the two grippers 352. During the movement of the clamp 100, the two rows of rollers 102 on both sides of the bottom end of the clamp 100 can roll on the connecting guide rails 3312 of the two support members 3311 respectively. Then, the gripper drive module drives the two grippers 352 to move away from each other, so that the gripper grooves 3521 of the two grippers 352 separate from the two protrusions 101 of the clamp 100 respectively. Then, the pick-and-place linear module 355 drives the pick-and-place base plate 351, two grippers 352, and gripper drive module to move towards the column 21 to the initial position. Then, the connecting linear module 332 drives the connecting platform 331 to move towards the column 21 to the initial position. Thus, the clamp 100 and the power battery fixed on the clamp 100 are placed into the compartment of the baking equipment.

[0065] After baking is completed, the loading platform 31 and the fork mechanism are first driven to rotate clockwise by a rotary drive mechanism, and the loading platform 31 and the fork mechanism are driven up and down by a lifting drive mechanism 22, so that the fork mechanism corresponds to the compartment of the baking equipment. Then, the connecting linear module 332 drives the connecting platform 331 to move towards the compartment of the baking equipment, so that the connecting platform 331 docks with the compartment of the baking equipment. At this time, the two rows of rollers 102 on both sides of the bottom end of the clamp 100 of the compartment of the baking equipment correspond to the connecting guide rails 3312 of the two support members 3311 of the connecting platform 331. Then, the two hooks 352 are driven away from each other by the hook drive module until the two hooks 352 protrude from both ends of the pick-and-place base plate 351. Then, the pick-and-place base plate 351, the two hooks 352, and the hook drive module are driven by the pick-and-place linear module 355 to move towards the compartment of the baking equipment until the clamp 100 of the compartment of the baking equipment is located between the two hooks 352 and the hook grooves 3521 of the two hooks 352 correspond to the two protrusions 101 of the clamp 100. Then, the two hooks 352 are driven closer to each other by the hook drive module so that the hook grooves 3521 of the two hooks 352 cooperate with the two protrusions 101 of the clamp 100. Then, the pick-and-place linear module 355 drives the pick-and-place base plate 351, the two hooks 352, and the hook drive module to move towards the column 21. Thus, the two hooks 352 can drive the clamp 100 and the power battery fixed on the clamp 100 to move towards the column 21. During the movement of the clamp 100, the two rows of rollers 101 on both sides of the bottom end of the clamp 100 can roll on the connecting guide rails 3312 of the two support members 3311 respectively, until the two rows of rollers 101 at the bottom end of the clamp 100 are respectively on the connecting guide rails 3312 of the two support members 3311. At this time, the pick-and-place base plate 351, the two hooks 352, and the hook drive module return to the initial position. In this way, the clamp 100 and the power battery fixed on the clamp 100 in the compartment of the baking equipment are dragged by the pick-and-place component 35 onto the connecting platform component 33. Then, the guide shaft 393 is driven upward by the push-pull electromagnet 392, so that the other end of the guide shaft 393 engages with the connecting hole at the bottom of the clamp 100, thereby locking the clamp 100 onto the docking platform assembly 33. Then, the two grippers 352 are driven away from each other by the gripper drive module, so that the gripper grooves 3521 of the two grippers 352 are separated from the two protrusions 101 of the clamp 100. Then, the docking linear module 332 drives the docking platform 331 and the clamp 100 to move towards the column 21 to the initial position.Then, the loading platform 31, fork mechanism, and clamp 100 are driven to rotate clockwise by the rotary drive mechanism, and the loading platform 31, fork mechanism, and clamp 100 are driven to move up and down by the lifting drive mechanism 22, so that the fork mechanism corresponds to the storage compartment position. At this time, the unlocking groove 3722 of the unlocking plate 372 corresponds to the cam follower at the bottom of the storage compartment door, and the docking platform 331 corresponds to the storage compartment position. Then, the door-opening linear module 373 drives the unlocking plate 372 to move towards the storage compartment, so that the unlocking groove 3722 of the unlocking plate 372 engages with the cam follower of the storage compartment. Then, the rotary drive mechanism drives the loading platform 31, fork mechanism, and clamp 100 to continue rotating clockwise. Pulled by the unlocking plate 372, the door of the storage compartment is opened. Then, the door-opening linear module 373 drives the unlocking plate 372 to move towards the column 21 back to its initial position, so that the unlocking groove 3722 of the unlocking plate 372 separates from the cam follower of the storage compartment. Then, the rotary drive mechanism drives the loading platform 31, fork mechanism, and clamp 100 to rotate counterclockwise, so that the fork mechanism returns to the position corresponding to the storage compartment. Then, the connecting linear module 332 drives the connecting platform 331 to move towards the storage compartment, so that the connecting platform 331 docks with the storage compartment. Next, the hook driving module drives the two hooks 352 to move closer together, so that the hook grooves 3521 of the two hooks 352 respectively engage with the two protrusions 101 of the clamp 100. Then, the push-pull electromagnet 392 drives the guide shaft 393 downwards, so that the other end of the guide shaft 393 separates from the connecting hole at the bottom of the clamp 100. Then, the pick-and-place linear module 355 drives the pick-and-place base plate 351, two grippers 352, gripper drive module, clamp 100, and power battery fixed on the clamp 100 to move towards the compartment closer to the cargo storage area. This allows the two grippers 352 to push the clamp 100 and the power battery into the cargo storage area. During the movement, the two rows of rollers 102 on both sides of the bottom of the clamp 100 roll on the connecting guide rails 3312 of the two support members 3311.

The rotating drive mechanism and the rotating base plate 112 drive the column device 20 and the loading platform device 30 to rotate, and the column device 20 drives the loading platform device 30 to move up and down. This allows the loading platform device 30 to be moved to a position corresponding to the location of the picking warehouse, the baking equipment warehouse, or the placing warehouse. By using the rotating device 10 instead of a walking device, there is no need for linear movement along a track on the ground.
