Description

Technical Field

[0001] This invention relates to the field of conveying structure technology, and in particular to a conveying and feeding mechanism for an overload protector assembly production line. Background Technology

[0002] In the field of industrial automation, overload protectors, as key circuit safety components, are widely used in various electrical equipment and power systems. Their production and assembly process usually relies on automated production lines, which are completed by sequentially installing and testing different parts at multiple continuously set workstations. In this production system, how to efficiently and accurately transfer and position the semi-finished protectors between various assembly workstations is one of the core links to ensure the smooth operation of the production line and the quality of the final product.

[0003] Currently, this transfer feeding process generally relies on a program-controlled robotic arm. Specifically, the robotic arm needs to perform a complex set of spatial trajectory movements in a loop: first, it moves horizontally to directly above the protector on the tooling, then moves vertically down to approach the workpiece, performs a gripping operation, then lifts vertically to a safe height, then retracts horizontally, and then moves to the next target station, repeating the series of actions of feeding, moving down, releasing the workpiece, moving up, and retracting, and finally resetting to prepare for the next cycle. This transfer mode forms the basis for the automated assembly and production of overload protectors. However, this transfer feeding method involves many steps when completing a workpiece transfer, requiring many drive units and control processes, resulting in high costs for equipment maintenance and assembly, as well as numerous structures and complex control. At the same time, the cyclic feeding process includes a large number of redundant idle strokes, resulting in a long single operation cycle and restricting the improvement of the overall production line's cycle time. Summary of the Invention

[0004] This invention provides a transmission and feeding mechanism for an overload protector assembly production line, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An overload protector assembly line conveying and feeding mechanism includes several carrier platforms for carrying the protector and a conveying structure for conveying the several carrier platforms. The conveying structure includes a first guide rail group and a second guide rail group that are distributed front to back and parallel to each other, two transfer units that are distributed left to right, and a transfer platform that can reciprocate between the first guide rail group and the second guide rail group. Both of the transfer units are disposed on the transfer platform. The transfer unit includes a guide rail group three that can dock with guide rail group one or guide rail group two. A side pusher is provided between guide rail group one and guide rail group two. The side pusher is used to push the support platform on guide rail group one or guide rail group two onto guide rail group three, or push the support platform on guide rail group three onto guide rail group one or guide rail group two. The support platform performs circumferential motion between guide rail group one and guide rail group two.

[0006] Furthermore, the support platform includes a platform plate that can slide on the first guide rail group, the second guide rail group, or the third guide rail group, and a downwardly extending vertical cylinder is provided in the middle of the platform plate, and a clamping structure for fixing the protector is provided inside the vertical cylinder; The clamping structure includes a plurality of side pressure bodies arranged in a ring and a support body disposed at the bottom of each of the side pressure bodies. The plurality of side pressure bodies and the plurality of support bodies can be brought close to each other or separated from each other. When the plurality of side pressure bodies are brought close to each other, they can form a cavity for clamping the protector. The plurality of support bodies can seal the bottom of the cavity.

[0007] Furthermore, the side pressure body slides relative to the corresponding support body and is connected by an elastic body, and the end of the side pressure body away from the cavity is provided with a retaining edge that cooperates with the support body; Each of the aforementioned side pressure bodies is provided with a locking structure for locking the side pressure body when it moves to a specified position.

[0008] Furthermore, the locking structure includes a first hook mounted on the stop edge and a second hook slidably disposed on the platform and used in conjunction with the first hook. The second hook and the platform are connected by an elastic body.

[0009] Furthermore, a toggle mechanism for opening the locking structure is provided between the side pressure body and the corresponding support body. The toggle mechanism includes a threaded tube rotatably disposed on the flange, a threaded rod screwed into the threaded tube, the threaded rod passing through the flange and fixedly connected to the support body, and a toggle body provided on the outer wall of the threaded tube.

[0010] Furthermore, an air hole is provided on the threaded tube. The air hole is conical in shape and has a cone body fitted inside it. The cone body is movable along the axis of the air hole via a movable frame that is slidably mounted on the threaded tube. The movable frame and the threaded tube are connected by an elastic body.

[0011] Furthermore, at least one slider is vertically slidably arranged on the outer wall of the vertical cylinder, and a corner bracket is rotatably arranged on the slider. One end of the corner bracket is rotatably connected to the corresponding support body. A collar is slidably sleeved on the vertical cylinder. The collar is rotatably connected to the other end of the corner bracket through a secondary rod. Two sliding columns are arranged on the outer wall of the collar. The feeding mechanism further includes two long slot plates respectively corresponding to the first guide rail group and the second guide rail group. The transfer unit further includes two auxiliary slot plates corresponding to the two long slot plates. The sliding column 2 is used in conjunction with the long slot plates and the auxiliary slot plates. One of the long slot plates is provided with a curved groove area for controlling the up and down movement of the collar.

[0012] Furthermore, the feeding mechanism also includes a fixed platform, the transfer platform slides on the fixed platform, a second slide is slidably provided on the fixed platform, the side pusher slides on the second slide via the first slide, and the sliding direction of the first slide on the second slide is perpendicular to the sliding direction of the second slide on the fixed platform. Two rows of right-angle levers are arranged opposite each other on the side pusher frame, and two pads are arranged opposite each other on the outer wall of the vertical cylinder. The pads are used in conjunction with the corresponding right-angle levers, and the right-angle levers are separated from the movement path of the support platform when it moves synchronously with the transfer platform.

[0013] Furthermore, a power unit for driving the side pusher to move is provided on the fixed platform. The power unit includes a square platform on the fixed platform and a power disk rotatably mounted on the square platform. An annular square groove is provided on the square platform, and a sliding column three is slidably disposed in the annular square groove. The sliding column three is rotatably connected to the side pusher. The power disk and the sliding column three are connected by a lever, and the lever is slidably disposed on the power disk.

[0014] Furthermore, a telescopic rod is rotatably mounted on the fixed platform, the movable end of the telescopic rod is rotatably connected to the transfer platform, and a push arm is rotatably mounted on the fixed end of the telescopic rod, the end of the push arm being slidably inserted into the slide table 2. The second slide moves in the same direction as the transfer platform.

[0015] The technical solution of this invention can achieve the following technical effects: It effectively solves the drawback of cumbersome transmission and feeding during the assembly of protectors, allowing the carrier platform to carry protectors directly and sequentially through each assembly station without having to repeatedly grab and transfer protectors from one station to another. This effectively simplifies the transmission mode, makes the transport of protectors simpler, shortens the single operation cycle, and improves production efficiency. At the same time, its structure and operation mode are simple, the cost is low, and it is easy to operate and maintain.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] like Figures 1 to 2 As shown, this application provides a conveying and feeding mechanism for an overload protector assembly production line, including a plurality of bearing platforms 200 for carrying protectors and a conveying structure for conveying the plurality of bearing platforms 200. The conveying structure includes a first guide rail group 100 and a second guide rail group 101 that are distributed front to back and parallel to each other, two transfer units that are distributed left to right, and a transfer table 102 that can reciprocate between the first guide rail group 100 and the second guide rail group 101. Both transfer units are disposed on the transfer table 102. The transfer unit includes a guide rail group three 103 that can dock with guide rail group one 100 or guide rail group two 101. A side pusher 104 is provided between guide rail group one 100 and guide rail group two 101. The side pusher 104 is used to push the support platform 200 on guide rail group one 100 or guide rail group two 101 onto guide rail group three 103, or push the support platform 200 on guide rail group three 103 onto guide rail group one 100 or guide rail group two 101. The support platform 200 performs circular motion between guide rail group one 100 and guide rail group two 101.

[0022] Specifically, both guide rail group one 100 and guide rail group two 101 are horizontally arranged, and each guide rail group one 100 and guide rail group two 101 corresponds to several processing stations for assembling overload protectors. Guide rail group one 100 and guide rail group two 101 can each be at least one guide rail, and the corresponding guide rail group three 103 can also be at least one guide rail. In this way, guide rail group three 103 can be used in conjunction with guide rail group one 100 and guide rail group two 101. In some embodiments, guide rail group one 100 and guide rail group two 101 can also be arranged vertically. The several processing stations corresponding to guide rail group one 100 and guide rail group two 101 can be stacked in space to reduce the overall footprint. Guide rail group three 103 can move between guide rail group one 100 and guide rail group two 101 as an intermediate body.

[0023] by Figure 2Taking the guide rail group 100 and guide rail group 201 as an example, which are arranged in a front-to-back manner on a horizontal plane, some of the bearing platforms 200 slide on guide rail group 100, and the remaining parts slide on guide rail group 201. The side pusher 104 can provide a driving force for the movement of the bearing platforms 200. Specifically, the side pusher 104 can push the bearing platforms 200 on guide rail group 201 to the left, so that each bearing platform 200 can move from one workstation to another. The leftmost bearing platform 200 on guide rail group 201 moves to guide rail group 303 on the left transfer unit. Then, the transfer table 102 is moved to the position of guide rail group 201, and the bearing platform 200 on the left transfer unit moves to the left side of guide rail group 100. At this time, the left guide rail group 303 corresponds to guide rail group 100. The side pusher 104 drives the bearing platforms 200 on guide rail group 100 to move to the right. Simultaneously, the carrier platform 200 on the left transfer unit is pushed onto the guide rail group 100, while the carrier platform 200 on the right side of the guide rail group 100 moves onto the right transfer unit. The transfer table 102 then moves towards the guide rail group 201. The right transfer unit carries the corresponding carrier platform 200 to the right side of the guide rail group 201, and the guide rail group 201 aligns with the right guide rail group 303. The side pusher 104 then pushes several carrier platforms 200 on the guide rail group 201 to the left, and the carrier platform 200 on the right transfer unit moves onto the guide rail group 201. The carrier platform 200 on the left side of the guide rail group 201 moves back to the left transfer unit. This process is repeated, so that the carrier platform 200 can gradually move to each workstation and stop for a specified time. At the same time, the cyclical movement of several carrier platforms 200 can realize the continuous transport and transfer of the protector, making it convenient to reuse several carrier platforms 200.

[0024] It should be noted that, in addition to the above-mentioned movement methods, several bearing platforms 200 on guide rail group two 101 can also be moved to the right, while several bearing platforms 200 on guide rail group one 100 can be moved to the left; when guide rail group one 100 and guide rail group two 101 are distributed vertically, the bearing platforms 200 perform circular motion in the vertical plane, and the bearing platforms 200 can also move to the left or right on guide rail group one 100 or guide rail group two 101. Thus, the cyclic movement and cyclic direction of the bearing platforms 200 in the horizontal plane, vertical plane or other planes can be selected and used according to actual needs.

[0025] To enable the above structure to be applicable to more processing stations, several stations can also be set on the movement path of each transfer unit, thereby allowing a large number of processing stations to be configured throughout the cyclical movement of the carrier platform 200.

[0026] In use, a loading station and a unloading station are set on guide rail group 100 or guide rail group 201 respectively. The loading station fixes the protector to be assembled on the carrier platform 200. The carrier platform 200 moves the protector to different stations for assembly along the trajectory of the conveying structure. When the protector moves to the unloading station, the protector assembly is completed and it can be removed. After the protector is removed, the carrier platform 200 continues to move to the loading station and performs a cyclical movement.

[0027] The technical solution of this invention effectively solves the drawback of cumbersome transmission and feeding during the assembly of protectors. It allows the carrier platform 200 to carry protectors directly and sequentially through each assembly station without having to repeatedly grab and transfer protectors from one station to another. This effectively simplifies the transmission mode, makes the transport of protectors simpler, shortens the single operation cycle, and improves production efficiency. At the same time, its structure and operation mode are simple, the cost is low, and it is easy to operate and maintain. Since the side pusher 104 only pushes a number of carrier platforms 200 on guide rail group one 100 or guide rail group two 101 to move at the same time, the carrier platforms 200 that are not pushed are in a stationary state, and the protectors on the carrier platforms 200 are in the assembly state. Thus, the assembly work and the transmission work can be separated and do not interfere with each other.

[0028] Furthermore, such as Figures 3 to 4 As shown, the support platform 200 includes a platform 201 that can slide on the guide rail group 100, the guide rail group 201 or the guide rail group 3 103. A vertical cylinder 202 extending downward is provided in the middle of the platform 201. A clamping structure 203 for fixing the protector is provided inside the vertical cylinder 202.

[0029] The platform 201 can be slidably connected to the guide rail assembly 100, guide rail assembly 201 or guide rail assembly 303 via a slider, or a groove can be directly set at the bottom of the platform 201; the vertical cylinder 202 is installed at the bottom of the platform 201, and the top of the vertical cylinder 202 directly penetrates the platform 201. This makes it easy to install the protector in the vertical cylinder 202 through the clamping structure 203. When the assembly is completed, the clamping structure 203 can be released directly to allow the protector to fall and be discharged through the vertical cylinder 202, without having to set up a gripping structure, robot or other structures separately for the unloading of the protector, which simplifies the structure and operation.

[0030] Furthermore, such as Figure 5 As shown, the clamping structure 203 includes a plurality of side pressure bodies 204 arranged in a ring and a support body 205 disposed at the bottom of each side pressure body 204. The plurality of side pressure bodies 204 and the plurality of support bodies 205 can be brought close to each other or separated from each other. When the plurality of side pressure bodies 204 are brought close to each other, they can form a cavity 206 for clamping the protector. The plurality of support bodies 205 can seal the bottom of the cavity 206.

[0031] Both the side-pressure body 204 and the support body 205 move radially along the annular shape they form, and both pass through the vertical cylinder 202 and are slidably connected to each other. Thus, the vertical cylinder 202 supports and guides the side-pressure body 204 and the support body 205. Several side-pressure bodies 204 are located in the upper layer, and the cavity 206 formed between them can be used to place and clamp the protector. Therefore, when the several side-pressure bodies 204 separate, they can simultaneously stop clamping the protector. When assembled, the several support bodies 205 can seal the bottom of the cavity 206, thereby supporting the bottom of the protector. This makes it convenient to place the protector directly between the separated side pressure bodies 204 during material loading. At this time, the several support bodies 205 that are close to each other can support the protector. Then, by bringing the several side pressure bodies 204 closer to each other, the protector can be clamped. This avoids the need for the several side pressure bodies 204 to be continuously fixed in a specific position by an external structure during the closing process, thus simplifying the operation.

[0032] The shape of the cavity 206 formed by several side pressure bodies 204 is consistent with the shape of the protector.

[0033] Furthermore, such as Figure 5 As shown, the number of side pressure bodies 204 is set to four, and the two adjacent side pressure bodies 204 and the two adjacent support bodies 205 are connected by a synchronous structure. The synchronization structure includes a sloping groove 207 formed on a side pressure body 204 or a support body 205 and a sloping arm 208 provided on an adjacent side pressure body 204 or a support body 205. The sloping arm 208 is provided with a sliding column 209 that can slide in the corresponding sloping groove 207.

[0034] When one side pressure body 204 or support body 205 is moved, the side pressure body 204 or support body 205 can use the cavity 206, the inclined groove 207 and the inclined arm 208 to push the adjacent side pressure body 204 or support body 205 to move. The movement of the adjacent side pressure body 204 or support body 205 will be transmitted to other side pressure bodies 204 or support bodies 205 through the synchronization structure, thereby making several side pressure bodies 204 and several support bodies 205 move synchronously. This structure only needs to control one side pressure body 204 or support body 205, which is simple to operate and has stronger synchronization of each structure.

[0035] In some embodiments, a power source such as a cylinder may be provided for each side pressure body 204 or support body 205.

[0036] Furthermore, such as Figure 5 As shown, the side pressure body 204 slides relative to the corresponding support body 205 and is connected by an elastic body 211. The end of the side pressure body 204 away from the cavity 206 is provided with a retaining edge 210 that cooperates with the support body 205. Each side pressure body 204 is provided with a locking structure for locking the side pressure body 204 when it moves to a specified position.

[0037] Since the side pressure body 204 and the support body 205 are connected by an elastic body 211, the elastic force provided by the elastic body 211 to the support body 205 will cause it to abut against the retaining edge 210, thereby keeping the side pressure body 204 and the support body 205 relatively stationary. After the protector on the support platform 200 is processed, it pushes the support body 205 to move outward. The support body 205 pushes the side pressure body 204 to move synchronously through the retaining edge 210 and the elastic body 211. When the side pressure body 204 moves to the specified position, the locking structure locks the side pressure body 204. At this time, the side pressure bodies 204 and the support bodies 205 are separated from each other, and the protector can fall away naturally through the gaps between the support bodies 205. When the support body 205 is pushed to reset, the side pressure bodies 204 cannot move due to the restriction of the locking structure, and the support bodies 205 gradually move closer together. At this time, the protector to be assembled can be placed on the support bodies 205, the locking structure is unlocked, and the side pressure bodies 204 move closer to each other under the action of the elastic body 211 and clamp the protector between them, thereby realizing the working mode of lifting first and then clamping.

[0038] Furthermore, such as Figure 4 and Figure 6 As shown, the locking structure includes a first hook 212 installed on the stop 210 and a second hook 213 slidably disposed on the platform 201 and used in conjunction with the first hook 212. The second hook 213 and the platform 201 are connected by an elastic body 214.

[0039] Both the outer end face of hook 1 212 and the end face of hook 2 213 facing the vertical cylinder 202 are set as inclined surfaces. This makes it easy to push hook 2 213 towards the side of hook 1 212 when hook 1 212 squeezes hook 2 213, so that hook 2 213 avoids hook 1 212. When hook 1 212 moves beyond hook 2 213, the pushing force of elastic body 2 214 on hook 2 213 will cause hook 2 213 to move towards hook 1 212 and lock together, thereby restricting the position of side pressure body 204. When it is necessary to unlock the locking structure, push hook 2 213 to separate from hook 1 212, so that side pressure body 204 and hook 1 212 can be reset. The moving direction of hook 2 213 on the platform 201 is perpendicular to the moving direction of elastic body 2 214 on the vertical cylinder 202.

[0040] Furthermore, such as Figures 6 to 7As shown, a toggle mechanism for opening the locking structure is provided between the side pressure body 204 and the corresponding support body 205. The toggle mechanism includes a threaded tube 215 rotatably mounted on the stop 210. A threaded rod 216 is threaded inside the threaded tube 215. The threaded rod 216 passes through the stop 210 and is fixedly connected to the support body 205. A toggle body 217 is provided on the outer wall of the threaded tube 215.

[0041] Since the threaded tube 215 and the threaded rod 216 are threadedly connected to each other, when the side pressure body 204 and the support body 205 move relative to each other, the threaded rod 216 will push the threaded tube 215 to rotate. The threaded tube 215 can drive the actuating body 217 to rotate synchronously. When the actuating body 217 rotates to the position of the second hook 213, the actuating body 217 can push the second hook 213 to slide on the platform 201, thereby controlling the second hook 213 to stop the locking work of the first hook 212, realizing the unlocking function of the locking structure.

[0042] Furthermore, such as Figure 7 As shown, an air hole 218 is provided on the threaded tube 215. The air hole 218 is conical in shape and a cone 219 is fitted inside it. The cone 219 is movable along the axis of the air hole 218 by a movable frame 220 that is slidably mounted on the threaded tube 215. The movable frame 220 and the threaded tube 215 are connected by an elastic body 221.

[0043] When the threaded tube 215 moves relative to the threaded rod 216, the internal space of the threaded tube 215 changes. At this time, the air inside the threaded tube 215 and the external air can flow through the gap between the air hole 218 and the cone 219. The limitation of the airflow velocity by the gap can provide a buffering effect for the threaded tube 215, thereby preventing the restoring elastic force provided by the elastic body 211 to the side pressure body 204 from causing the flange 210 to collide violently with the support body 205, thus improving the stability of the structure.

[0044] When the side pressure body 204 separates from the support body 205, external gas will be replenished into the threaded tube 215. At this time, the external gas will push the cone 219 to move away from the vent 218. That is, the restriction on airflow by the gap between the vent 218 and the cone 219 is reduced, and gas can be quickly replenished into the threaded tube 215. When the side pressure body 204 approaches the support body 205, the air inside the threaded tube 215 is discharged through the gap between the vent 218 and the cone 219. The flow of air will provide a driving force for the cone 219. The faster the side pressure body 204 resets, the smaller the gap between the vent 218 and the cone 219, and the stronger the restriction on airflow. Thus, the buffer strength can be automatically adjusted according to the reset speed of the side pressure body 204. When the cone 219 moves, it will drive the elastic body 221 to undergo elastic deformation through the moving frame 220. The elastic body 221 can provide reset elastic force for the cone 219. The moving frame 220 slides into the threaded tube 215.

[0045] Furthermore, such as Figure 4 , Figure 8 , Figure 10 and Figure 11 As shown, at least one slider 223 is vertically slidably arranged on the outer wall of the vertical cylinder 202. An angle bracket 222 is rotatably arranged on the slider 223. One end of the angle bracket 222 is rotatably connected to the corresponding support body 205. A collar 225 is slidably sleeved on the vertical cylinder 202. The other end of the collar 225 and the angle bracket 222 are rotatably connected through a secondary rod 224. Two sliding columns 226 are arranged on the outer wall of the collar 225. The feeding mechanism also includes two long slot plates 227 respectively corresponding to guide rail group 100 and guide rail group 201. The transfer unit also includes two auxiliary slot plates 228 corresponding to the two long slot plates 227. The sliding column 226 is used in conjunction with the long slot plates 227 and the auxiliary slot plates 228. One of the long slot plates 227 is provided with a curved groove area 229 for controlling the up and down movement of the collar 225.

[0046] When the collar 225 moves on the vertical cylinder 202, it will pull the corner bracket 222 to rotate on the slider 223 through the auxiliary rod 224. Utilizing the lever principle, the corner bracket 222 can push the support body 205 to move, thereby providing power for the opening and closing of the clamping structure 203. When the corner bracket 222 rotates, the vertical distance between it and the support body 205 changes, and the corner bracket 222 will drive the slider 223 to slide on the vertical cylinder 202.

[0047] Two elongated groove plates 227 correspond to guide rail assembly one 100 and guide rail assembly two 101, respectively, and are distributed opposite to each other. When one sliding pin 226 slides within one elongated groove plate 227, the other sliding pin 226 separates from the other elongated groove plate 227. Thus, when the bearing platform 200 moves on guide rail assembly one 100 or guide rail assembly two 101, the collar 225 can be positioned on the vertical cylinder by different sliding pins 226 engaging with the corresponding elongated groove plates 227. The position on 202 is restricted; the two sub-slot plates 228 on the transfer unit are set so that when the support platform 200 moves to the transfer unit, the two sliding pins 226 on the collar 225 can slide into the two sub-slot plates 228 respectively, and when the transfer unit moves to the position of guide rail group 100 or guide rail group 201, one sub-slot plate 228 can abut against the corresponding long slot plate 227, so as to facilitate the smooth transition of the corresponding sliding pin 226 from the sub-slot plate 228 to the long slot plate 227.

[0048] In order to control the vertical movement of the collar 225 on the vertical cylinder 202, a curved groove area 229 can be set on a long groove plate 227. When the sliding column 226 moves into the curved groove area 229, the sliding column 226 moves in the vertical direction, thereby pulling the collar 225 to move synchronously.

[0049] Furthermore, to ensure that the support platform 200 remains stationary after being moved to a fixed position and to prevent it from moving freely without restriction, the following can be adopted: Figures 9 to 11 As shown, each long slot plate 227 is provided with teeth, and the vertical cylinder 202 is provided with a rack 300 that works with the teeth on the two long slot plates 227. The rack 300 rotates on the vertical cylinder 202 through the inclined plate 301, and the rack 300 and the vertical cylinder 202 are connected by an elastic body 302. The rack 300 is a cylinder with teeth on the outer wall. The transfer unit also includes an electromagnet 303 for adsorbing and fixing the carrier platform 200 that has been moved to the transfer platform 102.

[0050] When the support platform 200 moves on the guide rail assembly 100 or the guide rail assembly 201, the rack 300 moves on the corresponding long slot plate 227. The elastic force provided by the elastic body 4 302 to the inclined plate 301 and the rack 300 allows the rack 300 to mesh with the teeth on the long slot plate 227. The pushing force on the support platform 200 is transmitted to the elastic body 4 302 and overcomes its elasticity, causing the inclined plate 301 and the rack 300 to rotate repeatedly and move on different teeth on the long slot plate 227. When the support platform 200 is stationary, the above meshing method can be used to lock and restrict the support platform 200, preventing it from moving arbitrarily. When the support platform 200 moves to the transfer unit, the electromagnet 303 can attract and fix the support platform 200, thereby preventing the support platform 200 from slipping off the transfer unit when moving with the transfer table 102 and improving the movement stability of the support platform 200.

[0051] When the carrier platform 200 moves with the transfer platform 102, the rack 300 on the inclined plate 301 can separate from the corresponding long slot plate 227. The cylindrical arrangement of the rack 300 allows it to smoothly roll toward the side of the long slot plate 227 and separate from the long slot plate 227.

[0052] It should be noted that when both the teeth on the rack 300 and the teeth on the long slot plate 227 are unidirectional, the bearing platform 200 is only allowed to move in one direction on the conveying structure.

[0053] like Figure 10 As shown, an auxiliary platform is set above the curved groove area 229 so that the teeth on the long groove plate 227 can be arranged continuously.

[0054] Furthermore, such as Figure 4 , Figure 12 and Figure 13As shown, the feeding mechanism also includes a fixed platform 400, a transfer platform 102 slides on the fixed platform 400, a second slide platform 402 is slidably provided on the fixed platform 400, and a side pusher 104 slides on the second slide platform 402 via a first slide platform 401, and the sliding direction of the first slide platform 401 on the second slide platform 402 is perpendicular to the sliding direction of the second slide platform 402 on the fixed platform 400. Two rows of right-angle levers 403 are arranged opposite each other on the side pusher 104, and two pads 404 are arranged opposite each other on the outer wall of the vertical cylinder 202. The pads 404 are used in conjunction with the corresponding right-angle levers 403, and the right-angle levers 403 and the carrier platform 200 are separated from each other when they move synchronously with the transfer platform 102.

[0055] Because the side pusher 104 needs to move several support platforms 200 on guide rail group one 100 to one side and several support platforms 200 on guide rail group two 101 to the other side, the side pusher 104 cannot simultaneously contact several support platforms 200 on guide rail group one 100 and guide rail group two 101. That is, when the side pusher 104 moves several support platforms 200 on guide rail group one 100, the side pusher 104 is in contact with several support platforms 200 on guide rail group two 101. The separation of 00 ensures that the several bearing platforms 200 on the first guide rail group 100 and the second guide rail group 101 can only move in one direction. In order to achieve the above purpose, the side pusher 104 needs to be able to move in the same direction as the transfer table 102. Combined with the movement mode of the side pusher 104 pushing the bearing platform 200, the side pusher 104 can move laterally and longitudinally on the horizontal plane. Therefore, it is necessary to use the first slide table 401 and the second slide table 402 to guide the side pusher 104.

[0056] When the support platform 200 moves from guide rail assembly one 100 to guide rail assembly two 101, the side pusher 104 and its several right-angle levers 403 will not interfere with the movement of the support platform 200. That is, the side pusher 104 and the several right-angle levers 403 need to be able to avoid the support platform 200. At the same time, since the movement direction of the support platform 200 on guide rail assembly one 100 and guide rail assembly two 101 is different, the pushing position of the right-angle levers 403 on the support platform 200 is also different. Therefore, it can make Figure 13 There is a gap in the lateral direction between the leftmost right-angled plate 403 in the upper row of right-angled plates 403 and the leftmost right-angled plate 403 in the next row of right-angled plates 403. This gap is the channel through which the support platform 200 moves with the transfer platform 102, and the support platform 200 needs to pass over the side push frame 104.

[0057] like Figure 4 The pad 404 is the contact position between the vertical cylinder 202 and the right-angle lever 403.

[0058] Furthermore, a power unit for driving the side pusher 104 to move is provided on the fixed platform 400. The power unit includes a square platform 405 provided on the fixed platform 400 and a power disk 407 rotatably provided on the square platform 405. An annular square groove 406 is provided on the square platform 405. A sliding column 409 is slidably provided in the annular square groove 406. The sliding column 409 is rotatably connected to the side pusher 104. The power disk 407 and the sliding column 409 are connected by a lever 408, and the lever 408 is slidably provided on the power disk 407.

[0059] The power disc 407 can be driven to rotate by a motor. The power disc 407 moves the sliding column 409 along the track of the annular square groove 406 via the lever 408. Figure 14 Based on the orientation, when the sliding column 3 409 moves laterally on the upper and lower sides of the annular square groove 406, the sliding column 3 409 pushes the side pusher 104 to move on the guide rail group 100 or the guide rail group 2 101; since the distance between the sliding column 3 409 and the axis of the power disk 407 changes when the sliding column 3 409 moves in the annular square groove 406, the lever 408 can slide on the power disk 407.

[0060] In some embodiments, multiple sets of power units can be provided, which can provide a more stable driving force for the side pusher 104.

[0061] Furthermore, such as Figure 12 As shown, a telescopic rod 410 is tilted and rotatably mounted on a fixed platform 400. The movable end of the telescopic rod 410 is rotatably connected to the transfer platform 102. A push arm 411 is rotatably mounted on the fixed end of the telescopic rod 410. The end of the push arm 411 is slidably inserted into the slide table 402. Among them, slide 2 402 and transfer platform 102 move in the same direction.

[0062] by Figure 14 Based on this, when the sliding column 3 409 moves longitudinally on the left and right sides of the annular square groove 406, the side pusher 104 moves synchronously. The side pusher 104 pushes the sliding table 2 402 to slide on the fixed platform 400. The sliding table 2 402 pushes the telescopic rod 410 to rotate on the fixed platform 400 through the push arm 411. The telescopic rod 410 moves the transfer table 102 on the fixed platform 400, thereby providing power to the transfer table 102 and its two transfer units, and making full use of the entire movement trajectory of the sliding column 3 409 in the annular square groove 406.
