Description

Technical Field

[0001] This invention belongs to the field of mechanical equipment technology, and in particular relates to an assembly and unloading device. Background Technology

[0002] Before assembling the housing of the DC charging gun, the terminal body and the waterproof protective cap need to be pre-assembled as one unit. Specifically, the terminal body and the waterproof protective cap are connected by an interference fit. During assembly, a certain pressing force needs to be applied to the waterproof protective cap or the terminal body to press the waterproof protective cap into and fasten it to the corresponding part of the terminal body, thereby achieving a reliable assembly between the two.

[0003] Currently, protective cap feeding typically employs a vibratory feeder in conjunction with a vibratory track. After being shaped by the vibratory feeder, the protective caps are sequentially conveyed to the picking station along the vibratory track. Due to the irregular shape of the protective caps, and the tendency for some caps to stack, jam, or shift during the vibratory conveying process, material jamming frequently occurs at the exit of the vibratory track or at the picking position. This prevents the protective caps from being accurately conveyed one by one to the preset picking location. Once jamming occurs, manual intervention is required to restore feeding, which not only reduces the continuity and stability of feeding but also affects subsequent assembly processes, increasing equipment downtime and labor maintenance costs.

[0016] The beneficial effects that this invention can achieve are: This invention relates to an assembly and unloading device, comprising a turntable mechanism, a first workpiece loading mechanism, a second workpiece loading mechanism, an assembly mechanism, and a finished product unloading mechanism. The assembly and unloading device utilizes a first workpiece distribution component, which includes a storage base and a distribution element. The reciprocating movement of the distribution plate guides the movement of a follower element and the storage base via the guide groove wall, causing the storage tank to switch between a first position and a second position. In the first position, the storage tank is in a receiving state, allowing a single first workpiece to enter; in the second position, the storage tank is in a closed state, preventing the entry of a first workpiece. The material distribution plate reciprocates, driving the storage tank to switch between receiving and stopping states. In the receiving state (first position), the storage tank is directly opposite the upstream feed port, and a single first workpiece enters the storage tank under the force of feeding. In the stopping state (second position), the storage tank is offset from the feed port, preventing subsequent workpieces from entering. This ensures that only one workpiece is output per distribution action, avoiding over-distribution, stacking, or leakage, thus guaranteeing the accuracy and consistency of feeding and improving the assembly efficiency and operational reliability of the assembly and unloading equipment.

[0020] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0023] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0025] Before assembling the housing of the DC charging gun, the terminal body and the waterproof protective cap need to be pre-assembled as one unit. Specifically, the terminal body and the waterproof protective cap are connected by an interference fit. During assembly, a certain pressing force needs to be applied to the terminal body to press it into and secure it to the corresponding part of the waterproof protective cap, thereby achieving a reliable assembly between the two.

[0026] Currently, protective cap feeding typically employs a vibratory feeder in conjunction with a vibratory track. After being shaped by the vibratory feeder, the protective caps are sequentially conveyed to the picking station along the vibratory track. Due to the irregular shape of the protective caps, and the tendency for some caps to stack, jam, or shift during the vibratory conveying process, material jamming frequently occurs at the exit of the vibratory track or at the picking position. This prevents the protective caps from being accurately conveyed one by one to the preset picking location. Once jamming occurs, manual intervention is required to restore feeding, which not only reduces the continuity and stability of feeding but also affects subsequent assembly processes, increasing equipment downtime and labor maintenance costs.

[0027] For the above issues, please refer to Figure 1-16This invention provides an assembly and unloading device 100, including a turntable mechanism 10, a first workpiece loading mechanism 20, a second workpiece loading mechanism 30, an assembly mechanism 40, and a finished product unloading mechanism 60. The turntable mechanism 10 includes a turntable 11, with a first workstation 11A, a second workstation 11B, and an assembly workstation 11C sequentially arranged along its circumference. The first workpiece loading mechanism 20 is configured corresponding to the first workstation 11A and is used to load a first workpiece A onto the first workstation 11A. The first workpiece loading mechanism 20 includes a first workpiece distributing component 22, which includes a storage base 221 and a distributing element 222. The storage base 221 has a storage groove 221A for accommodating a single first workpiece A. The distributing element 222 includes a follower element 2221 and a distributing plate 2222. The follower element 2221 is fixedly installed on the storage base 221, and the distributing plate 2222 has... A guide groove 2222A is provided, and the follower 2221 passes through the guide groove 2222A. When the material distribution plate 2222 reciprocates, it drives the follower 2221 and the storage seat 221 to reciprocate through the groove wall of the guide groove 2222A, so that the storage trough 221A switches between a first position and a second position. In the first position, the storage trough 221A is in a receiving state, allowing a single first workpiece A to enter the storage trough 221A. In the second position, the storage trough 221A is in a closed state to prevent the first workpiece A from entering. A second workpiece loading mechanism 30 is provided corresponding to the second station 11B and is used to load the second workpiece B to the second station 11B. An assembly mechanism 40 is provided corresponding to the assembly station 11C and is used to assemble the first workpiece A and the second workpiece B into a finished product. A finished product unloading mechanism 60 is used to unload the finished product.

[0028] In this embodiment, the assembly and unloading equipment 100 is used to assemble the first workpiece A and the second workpiece B into a finished product. For example, it can be used to assemble the terminal body of a DC charging gun with the waterproof protective cap through an interference fit. It can also be applied to other two workpieces that require press-fitting, snap-fitting, or riveting. The assembly and unloading equipment 100 includes a turntable mechanism 10, a first workpiece loading mechanism 20, a second workpiece loading mechanism 30, an assembly mechanism 40, and a finished product unloading mechanism 60.

[0029] The turntable mechanism 10 is provided with a turntable 11, which has a first workstation 11A, a second workstation 11B, and an assembly workstation 11C arranged sequentially along its circumference. The turntable 11 rotates intermittently between the workstations to sequentially transfer the workpieces carried on it to each processing position.

[0030] Each of the first workstation 11A, the second workstation 11B and the assembly workstation 11C is provided with a corresponding support seat 12. The support seat 12 is fixedly mounted on the turntable 11 and has a receiving groove 12A.

[0031] Each of the first workstation 11A, the second workstation 11B, and the assembly workstation 11C is provided with a corresponding support seat 12. The support seat 12 is fixedly installed on the turntable 11 and rotates synchronously with the turntable 11. Each support seat 12 is used to support the workpiece at the corresponding workstation to ensure that the workpiece maintains a stable position and posture during the rotation of the turntable 11. The support seat 12 has a receiving groove 12A, the shape of which is adapted to the shape of the workpiece at the corresponding workstation, for positioning and limiting the workpiece. Specifically, the receiving groove 12A of the support seat 12 can simultaneously accommodate and position the first workpiece A, the second workpiece B, the assembly component composed of the first workpiece A and the second workpiece B, and the finished product. Through the contour positioning function of the receiving groove 12A, the positional accuracy of the workpiece during the transfer and assembly process can be ensured, avoiding the impact of workpiece offset on material handling or assembly quality. In addition, the bottom of the receiving groove 12A may be provided with an adsorption hole to cooperate with the external air passage to achieve vacuum adsorption, further fix the workpiece, and prevent the workpiece from moving or falling off when the turntable 11 rotates at high speed.

[0032] The turntable mechanism 10 also includes a turntable drive assembly 13, and the turntable 11 is connected to the output end of the turntable drive assembly 13.

[0033] The turntable drive assembly 13 provides rotational power to the turntable 11, driving the turntable 11 to perform intermittent indexing rotation at preset angles and times. The turntable drive assembly 13 can be in the form of a divider, a DD motor, or a servo motor in conjunction with a reducer, and its output end is fixedly connected to the center of the turntable 11 via a flange or coupling.

[0034] The turntable mechanism 10 also includes a buffer assembly 14, which is set corresponding to the assembly station 11C and located on the back of the turntable 11. The buffer assembly 14 includes a buffer cylinder 141 and a buffer pad 142, and the buffer pad 142 is connected to the output end of the buffer cylinder 141.

[0035] The buffer assembly 14 provides a reverse support force to the turntable 11 when the assembly mechanism 40 performs the pressing action, thereby counteracting the impact load generated during the pressing process and preventing the turntable 11 from deforming or shaking due to excessive force, thus ensuring assembly accuracy and equipment stability. Specifically, the buffer assembly 14 includes a buffer cylinder 141 and a buffer pad 142, with the buffer pad 142 connected to the output end of the buffer cylinder 141. The buffer cylinder 141 is fixedly installed on the frame or mounting plate of the assembly unloading equipment 100, with its output end facing upwards and directly opposite the back of the turntable 11. When the turntable 11 rotates to the assembly station 11C and the first workpiece A and the second workpiece B are supported on the bearing seat 12, the buffer cylinder 141 extends, pushing the buffer pad 142 upwards and abutting against the back of the turntable 11, providing rigid support for the turntable 11 during the pressing process. After the assembly mechanism 40 completes the pressing action, the buffer cylinder 141 retracts, causing the buffer pad 142 to detach from the back of the turntable 11, thereby releasing the support and allowing the turntable 11 to continue rotating to the next station. By setting the buffer assembly 14, the pressing stability of the assembly station 11C can be effectively improved, avoiding the turntable 11 from sinking or swaying due to the pressing reaction force, thereby improving the assembly accuracy and consistency of the first workpiece A and the second workpiece B.

[0036] The first workpiece loading mechanism 20 is used to pick up the first workpieces A one by one from the feeding source and transfer them to the carrier 12 of the first station 11A of the turntable 11. The first workpiece loading mechanism 20 can adopt various feeding methods, including but not limited to vibratory feeder feeding, tray feeding, roll feeding, or pallet feeding. The first workpiece loading mechanism 20 includes a feeding unit and a transfer unit. The feeding unit is used to arrange the first workpieces A in a predetermined direction and output them at a set rhythm. The transfer unit is used to pick up the first workpieces A output by the feeding unit and place them on the carrier 12 of the first station 11A.

[0037] The feeding unit of the first workpiece feeding mechanism 20 includes a first workpiece separating component 22. The first workpiece separating component 22 is used to separate the first workpieces A that are transported to the first workpiece separating component 22 one by one to avoid multiple first workpieces A entering the picking position at the same time and causing jamming. The first workpiece separating component 22 includes a storage base 221 and a separating component 222. The storage base 221 has a storage groove 221A for accommodating a single first workpiece A. The separating component 222 includes a follower 2221 and a separating plate 2222. The follower 2221 is fixedly installed on the storage base 221. The separating plate 2222 has a guide groove 2222A. The follower 2221 passes through the guide groove 2222A. When the material plate 2222 reciprocates, the guide groove 2222A drives the follower 2221 and the storage seat 221 to reciprocate, causing the storage trough 221A to switch between a first position and a second position. In the first position, the storage trough 221A is in a receiving state, allowing a single first workpiece A to enter the storage trough 221A. In the second position, the storage trough 221A is in a cut-off state to prevent the first workpiece A from entering. The material distribution plate 2222 reciprocates, driving the storage seat 221 to switch between receiving and stopping states. In the receiving state (first position), the storage tank 221A faces the upstream feed port, and a single first workpiece A enters the storage tank 221A under the feeding force. In the stopping state (second position), the storage tank 221A deviates from the feed port, preventing subsequent first workpieces A from entering. This ensures that only one first workpiece A is output per distribution action, avoiding overfilling, stacking, or leakage, thus guaranteeing the accuracy and consistency of feeding and improving the assembly efficiency and operational reliability of the assembly unloading equipment 100. The first workpiece A can be a protective cap or other components to be assembled. The guide groove 2222A is an annular closed groove, including a propulsion section and a reset section. The propulsion section is close to the upstream feed port, and the reset section is far from the upstream feed port.

[0038] The second workpiece loading mechanism 30 is configured corresponding to the second station 11B and is used to load the second workpiece B onto the second station 11B. The second workpiece loading mechanism 30 is used to remove the second workpiece B one by one from the feeding source and transfer them to the support seat 12 of the second station 11B on the turntable 11. The second workpiece loading mechanism 30 can adopt various feeding methods, including but not limited to vibratory feeder feeding, tray feeding, roll feeding, or pallet feeding. The second workpiece loading mechanism 30 includes a feeding unit and a transfer unit. The feeding unit is used to arrange the second workpiece B in a predetermined direction and output it at a set rhythm. The transfer unit is used to pick up the second workpiece B output by the feeding unit and place it on the support seat 12 of the second station 11B. Under the coordinated control of the control system, each component of the second workpiece loading mechanism 30 operates according to a preset timing sequence, sequentially completing feeding, picking, posture adjustment, transfer, and positioning, thereby achieving automated and efficient loading of the second workpiece B. The second workpiece B can be a terminal or other components to be assembled.

[0039] Assembly mechanism 40 is provided corresponding to assembly station 11C and is used to assemble the first workpiece A and the second workpiece B into a finished product. Assembly mechanism 40 can adopt any applicable assembly method such as press fitting, hot pressing, riveting, or snap-fit. Assembly mechanism 40 includes assembly base 41, assembly drive component 42, and pressing head 446 for performing press fitting. The assembly drive component 42, such as a cylinder, hydraulic cylinder, or servo electric cylinder, drives the pressing head 446 to move along a set assembly direction, applying a set pressure or displacement to the mating parts of the first workpiece A and the second workpiece B, so that the two are fastened together by interference fit, elastic deformation, or plastic deformation. When the turntable 11 rotates the station carrying the first workpiece A and the second workpiece B to assembly station 11C, assembly mechanism 40 starts to complete the final assembly of the two, forming the assembled finished product.

[0040] This invention proposes an embodiment, see [link to embodiment]. Figure 1 , 56. Both the second workpiece loading mechanism 30 and the finished product unloading mechanism 60 are equipped with a tray conveying assembly 31. The tray conveying assembly 31 includes a first hopper 311, a second hopper 312, a tray support 313, and a pusher assembly 314. The bottom of the first hopper 311 has a first compartment 311A, which is used to supply trays C. The bottom of the second hopper 312 has a second compartment 312A, which is used to receive trays C. The tray support 313 is located between the first hopper 311 and the second hopper 312, forming a material handling station 313A. The pusher assembly 314 is located at the bottom of the first hopper 311 and the second hopper 312, and has a pusher surface 31411 for pushing against the side of the tray C, and pushes along the first hopper 311 towards the second hopper 312. The hopper 312 moves back and forth in the direction of movement; when the pusher assembly 314 moves from the first hopper 311A ​​to the second hopper 312A, the pusher surface 31411 pushes a single tray C from the first hopper 311A ​​through the loading and unloading station 313A to the second hopper 312A; when the pusher assembly 314 retracts from the second hopper 312A to the first hopper 311A, the pusher surface 31411 disengages from the side of the tray C; in the second workpiece loading mechanism 30, the first hopper 311 contains a full tray C carrying the second workpiece B, and the second hopper 312 is used to receive an empty tray C; in the finished product unloading mechanism 60, the first hopper 311 contains an empty tray C, and the second hopper 312 is used to receive a full tray C carrying the finished product.

[0041] In this embodiment, the tray conveying assembly 31 is used to realize the automatic supply, conveying and recycling of the tray C, so as to realize the continuous and automated loading and unloading operation of the second workpiece B or the finished product. The tray conveying assembly 31 includes a first hopper 311, a second hopper 312, a tray bracket 313 and a tray pusher assembly 314.

[0042] The first hopper 311 has a first compartment 311A ​​at its bottom, which is used to supply trays C. Multiple trays C are stacked within the first hopper 311, and each tray C falls sequentially to the first compartment 311A ​​under external driving force for being pushed by the tray pusher assembly 314. The second hopper 312 has a second compartment 312A at its bottom, which is used to receive trays C pushed from the first compartment 311A. A tray support 313 is located between the first hopper 311 and the second hopper 312, forming a pick-and-place station 313A. The pick-and-place station 313A provides operating space for operators or external automated equipment, such as robotic arms or pick-and-place assemblies, to pick up and place workpieces. The bearing surface of the tray support 313 is coplanar with the tray bearing surfaces at the first compartment 311A ​​and the second compartment 312A to ensure that the trays C move smoothly during the pushing process, avoiding jamming or tilting.

[0043] The pusher assembly 314 is located at the bottom of the first hopper 311 and the second hopper 312, and has a pusher surface 31411 for pushing against the side of the hopper C, and reciprocates along the direction from the first hopper 311 to the second hopper 312. The stroke of the pusher assembly 314 covers at least the entire distance from the first hopper 311A ​​through the material handling station 313A to the second hopper 312A.

[0044] When the pusher assembly 314 moves from the first compartment 311A ​​to the second compartment 312A, the pusher surface 31411 pushes against the side of a single tray C, pushing the single tray C out of the first compartment 311A ​​and then through the pick-and-place station 313A to the second compartment 312A. During this process, the tray C is supported by the tray bracket 313. When a pick-and-place mechanism is provided at the pick-and-place station 313A, workpiece pick-and-place operations can be performed while the tray C is stationed at the pick-and-place station 313A. When the pusher assembly 314 retracts from the second compartment 312A to the first compartment 311A, the pusher surface 31411 disengages from the side of the tray C to avoid bringing the tray C, which has been pushed to the second compartment 312A, back during the retraction process.

[0045] In the second workpiece feeding mechanism 30, the first hopper 311 contains a full tray C carrying the second workpiece B, and the second hopper 312 is used to receive empty trays C. That is, during the operation, the pusher assembly 314 pushes the trays C fully loaded with the second workpiece B from the first hopper 311 to the pick-and-place station 313A one by one, so that the second workpiece picking assembly 32, the second workpiece transferring assembly 34, or the operator can remove the second workpiece B from the tray C. After all the second workpiece B on the tray C has been removed, the pusher assembly 314 continues to push the empty tray C into the second hopper 312 for stacking and recycling.

[0046] In the finished product unloading mechanism 60, empty trays C are stacked in the first hopper 311, and the second hopper 312 is used to receive full trays C that have already carried the finished products. That is, during the operation, the pusher assembly 314 pushes the empty trays C one by one from the first hopper 311 to the material handling station 313A. The finished product handling assembly 61 or a person places the qualified finished products into the empty trays C. After the trays C are full of finished products, the pusher assembly 314 continues to push the full trays C into the second hopper 312 for stacking and recycling.

[0047] This invention proposes an embodiment, see [link to embodiment]. Figure 10 The pusher assembly 314 includes a pusher claw 3141, a movable seat 3142, a pusher transmission component 3143, and a pusher drive component 3144. The pusher claw 3141 is fixed to the movable seat 3142 and forms the pusher surface 31411. One end of the movable seat 3142 is fixedly connected to the pusher transmission component 3143 and is driven by the pusher transmission component 3143 to reciprocate between the first hopper 311 and the second hopper 312. The pusher transmission component 3143 is driven by the pusher drive component 3144.

[0048] In this embodiment, the pusher assembly 314 includes a pusher claw 3141, a movable base 3142, a pusher transmission component 3143, and a pusher drive component 3144. The pusher claw 3141 is fixedly installed on the upper end face of the movable base 3142 and forms the pushing surface 31411. The pushing surface 31411 is a vertical plane perpendicular to the pushing direction or an inclined plane with a slight inclination angle, used to form surface contact with the side of the material tray C to smoothly push the material tray C to move.

[0049] One end of the movable seat 3142 is fixedly connected to the push plate transmission component 3143 and driven by the push plate transmission component 3143 to reciprocate horizontally between the first hopper 311 and the second hopper 312. The movable seat 3142 can be a plate-like structure or a frame structure, and its bottom is provided with a sliding fit structure, such as a slider or a linear bearing, to slide with the guide component, ensuring the linearity and stability of the movable seat 3142 during reciprocating movement. The other end of the movable seat 3142 can be slidably mounted on the guide component to provide auxiliary support and guidance, preventing the movable seat 3142 from deflecting or tilting during the pushing process.

[0050] The pusher drive component 3143 is driven by the pusher drive component 3144. The pusher drive component 3143 transmits the rotational or linear motion output by the pusher drive component 3144 to the movable seat 3142, driving the movable seat 3142 to reciprocate along a preset direction. Preferably, the pusher drive component 3143 employs a synchronous belt drive mechanism, including a driving pulley, a driven pulley, and a synchronous belt wound between them. The driving pulley is connected to the output end of the pusher drive component 3144, and one end of the movable seat 3142 is fixedly connected to the synchronous belt, moving with the reciprocating motion of the synchronous belt. In other embodiments, the pusher drive component 3143 can also employ any suitable linear transmission form such as a screw and nut mechanism, a gear and rack mechanism, or a chain drive mechanism, as long as it can transmit the power of the pusher drive component 3144 to the linear reciprocating motion of the movable seat 3142.

[0051] The pusher drive component 3144 can be any suitable power source such as a stepper motor, servo motor, cylinder, or hydraulic cylinder. The pusher drive component 3144 is fixedly installed on the mounting base or equipment frame of the material tray conveying assembly 31, and is connected to the moving seat 3142 through the pusher transmission component 3143.

[0052] During operation, the pusher drive 3144 is activated, driving the moving seat 3142 from the first hopper 311 to the second hopper 312 via the pusher transmission 3143. The pushing surface 31411 of the pusher claw 3141 pushes against the side of a single tray C located at the first hopper 311A, pushing the tray C from the first hopper 311A ​​to the pick-and-place station 313A and finally to the second hopper 312A. Subsequently, the pusher drive 3144 reverses its direction, causing the moving seat 3142 to retract from the second hopper 312 towards the first hopper 311, with the pusher claw 3141 retracting along with the moving seat 3142. This cycle repeats continuously, achieving the sequential pushing of trays C.

[0053] This invention proposes an embodiment, see [link to embodiment]. Figure 8The first hopper 311 includes a first support frame 3111, a chain 3112, shelves 3113, a first hopper transmission component 3114, and a first hopper drive component 3115. The first support frame 3111 forms a first cavity 3111A. The chain 3112 is rotatably mounted on the first support frame 3111. A plurality of shelves 3113 are located in the first cavity 3111A and fixed on the chain 3112, and are distributed parallel to each other along the transmission direction of the chain 3112. The distance between two adjacent shelves 3113 is adapted to the thickness of a single tray C. The pusher assembly 314 is located below the shelves 3113, and the movement path of the pusher assembly 314 passes through the first cavity 3111A. The first hopper drive component 3115 drives the chain 3112 to move through the first hopper transmission component 3114, so that the trays C on the shelves 3113 fall sequentially into the first hopper 311A.

[0054] In this embodiment, the first hopper 311 includes a first support frame 3111, a chain 3112, a shelf 3113, a first hopper transmission component 3114, and a first hopper drive component 3115. The first support frame 3111 is a vertically arranged frame structure with a first cavity 3111A inside, which is used to accommodate stacked trays C. The chain 3112 consists of two parallel chains, which are rotatably mounted on opposite sides of the first support frame 3111 and arranged in a ring along the vertical direction. They are driven synchronously by the first hopper drive component 3115 through the first hopper transmission component 3114.

[0055] Multiple shelves 3113 are located within the first cavity 3111A and fixed between two chains 3112, and are distributed parallel to each other along the transmission direction of the chains 3112. The spacing between two adjacent shelves 3113 is adapted to the thickness of a single tray C, that is, the spacing is slightly larger than the thickness of a single tray C, so that each shelf 3113 can support one tray C, and adjacent trays C do not interfere with each other. The shelf 3113 may be an L-shaped bent plate or a flat plate, one end of which is fixed to the chain 3112, and the other end extends into the first cavity 3111A to support the edge of the tray C from the bottom. Preferably, the shelf 3113 is fixedly connected to the links of the chain 3112 by a hinge or a fixing block, and moves synchronously with the rotation of the chain 3112. When the chain 3112 is running, each shelf 3113 moves in a circular motion in the vertical direction, passing through the first compartment 311A ​​in sequence.

[0056] The pusher assembly 314 is located below the shelf 3113, and its movement path passes through the first cavity 3111A, meaning the pusher assembly 314 pushes horizontally through the bottom region of the first cavity 3111A. The first hopper drive 3115 drives the chain 3112 via the first hopper transmission 3114, causing the trays C on the shelf 3113 to fall sequentially into the first compartment 311A. Specifically, when the bottom shelf 3113 moves to the bottom first compartment 311A ​​with the chain 3112, the chain 3112 stops moving, and the shelf 3113 and its trays C remain stationary. At this time, the pusher assembly 314 is activated, and its pusher surface 31411 directly pushes against the side of the bottom tray C located on the shelf 3113, pushing the tray C directly out of the shelf 3113 in the horizontal direction to the material pick-up and drop station 313A of the tray bracket 313, and finally to the second station 11B.

[0057] Preferably, the first hopper transmission component 3114 is a sprocket transmission mechanism, and the first hopper drive component 3115 is a stepper motor or a servo motor.

[0058] This invention proposes an embodiment, see [link to embodiment]. Figure 5 , 6 9. The second hopper 312 includes a second support frame 3121, a support assembly 3122, a lifting drive 3123, and a receiving tray 3124; the second support frame 3121 forms a second cavity 3121A; the support assembly 3122 is located above the receiving tray 3124 and is used to support the tray; the lifting drive 3123 is installed in the second cavity 3121A; the receiving tray 3124 is fixed to the output end of the lifting drive 3123 and is correspondingly arranged with the support assembly 3122; the lifting drive 3123 is used to drive the receiving tray 3124 to move up and down in the vertical direction.

[0059] In this embodiment, the second hopper 312 serves as the receiving end of the material tray C, and is used to receive and stack the individual material trays C pushed by the pusher assembly 314 in sequence. It includes a second support frame 3121, support assemblies 3122 and 3122', a lifting drive 3123, and a receiving tray 3124.

[0060] The second support frame 3121 is the main skeleton structure of the second hopper 312, and has sufficient structural strength to support the multi-layer stacked trays C and the weight of the materials they carry. The second support frame 3121 has a second cavity 3121A, which extends vertically through the interior of the second support frame 3121, providing space for the stacking and lifting of the trays C.

[0061] The support components 3122 and 3122' are located above the receiving tray 3124 and are used to support the material tray C. They can support one material tray C or multiple material trays C.

[0062] The lifting drive component 3123 is installed in the second cavity 3121A, and it can be a linear drive element such as a servo motor in conjunction with a lead screw and nut mechanism, a linear module, a cylinder, or a hydraulic cylinder. In this embodiment, a lead screw lifting mechanism driven by a servo motor is preferred.

[0063] The receiving tray 3124 is fixed to the output end of the lifting drive component 3123 and is correspondingly arranged with the support components 3122 and 3122'. The receiving tray 3124 is a horizontally arranged flat plate whose area is adapted to the bottom surface of the tray C, and is used to receive a single tray C pushed from the pusher component 314. The lifting drive component 3123 is used to drive the receiving tray 3124 to move up and down in the vertical direction, thereby realizing the cumulative storage of stacked trays C.

[0064] This invention proposes an embodiment, see [link to embodiment]. Figure 9 The support component 3122 includes a mounting block 31221, a support block 31222, and an elastic element 31223. The mounting block 31221 is fixed to the second support frame 3121, and the support block 31222 is rotatably connected to the mounting block 31221. One end of the elastic element 31223 passes through and abuts against the support block 31222, and the other end abuts against the mounting block 31221. The lifting drive component 3123 is used to drive the receiving tray 3124 to rise, so that the bearing surface of the receiving tray 3124 is coplanar with the bearing surface of the tray bracket 313, so as to receive the tray C pushed from the material handling station 313A to the second compartment 312A. The lifting drive 3123 is also used to continue driving the receiving tray 3124 to rise after receiving the tray C. The tray C rises synchronously with the receiving tray 3124 and pushes against the support block 31222, causing the support block 31222 to rotate and avoid it. After the tray C passes the support block 31222, the elastic element 31223 drives the support block 31222 to reset so as to support the tray C and perform stacking.

[0065] In this embodiment, the support component 3122 of the second hopper 312 is used to support the trays C, enabling the stacking of multiple trays C. The support component 3122 specifically includes a mounting block 31221, a support block 31222, and an elastic element 31223.

[0066] The mounting block 31221 is fixed to the inner wall of the second support frame 3121, serving as the mounting base for the support assembly 3122. The mounting block 31221 can be a metal block fixed to a preset height on the inner wall of the second cavity 3121A by screws or welding. There are multiple mounting blocks, preferably four, located at the four corners of the second cavity 3121A, to ensure uniform and stable support force for the material tray C.

[0067] The support block 31222 is rotatably connected to the mounting block 31221. Specifically, the support block 31222 can be mounted on the mounting block 31221 via a pivot or hinge, allowing it to swing about a pivot in a vertical plane. One end of the support block 31222 extends into the second cavity 3121A to support the material tray C; its other end engages with the elastic element 31223.

[0068] One end of the elastic element 31223 passes through and abuts against the support block 31222, and the other end abuts against the mounting block 31221. In this embodiment, the elastic element 31223 can be a compression spring or a torsion spring. When a compression spring is used, one end of the spring is embedded in the limiting hole or groove of the support block 31222, and the other end abuts against the corresponding abutting surface of the mounting block 31221.

[0069] The lifting drive 3123 is used to drive the receiving tray 3124 to rise, so that the bearing surface of the receiving tray 3124 is coplanar with the bearing surface of the tray bracket 313, so as to receive the tray C pushed from the material handling station 313A to the second compartment 312A. The lifting drive 3123 is also used to continue to drive the receiving tray 3124 to rise after receiving the tray C. The tray C rises synchronously with the receiving tray 3124 and pushes against the support block 31222, causing the support block 31222 to rotate and avoid it. After the tray C passes the support block 31222, the elastic member 31223 drives the support block 31222 to return to its original position to support the tray C for stacking.

[0070] In this embodiment, the stacking process of the second hopper 312 is as follows: First, the lifting drive 3123 drives the receiving tray 3124 to rise, making the bearing surface of the receiving tray 3124 coplanar with the bearing surface of the tray bracket 313. At this time, the pusher assembly 314 pushes a single tray C from the loading / unloading station 313A to the second compartment 312A. The tray C enters the second cavity 3121A and is completely located on the upper surface of the receiving tray 3124, where it is received.

[0071] Then, after receiving the material tray C, the lifting drive 3123 continues to drive the receiving tray 3124 to rise. The material tray C rises synchronously with the receiving tray 3124. When the upper surface edge of the material tray C contacts and pushes against the support block 31222, the upward thrust of the material tray C overcomes the elastic potential energy of the elastic member 31223, forcing the support block 31222 to rotate towards the second support frame 3121, thereby avoiding the rising path of the material tray C.

[0072] Next, after the material tray C has completely passed the support block 31222, the elastic element 31223 drives the support block 31222 to rotate in the opposite direction and reset. At this time, the lifting drive element 3123 drives the receiving tray 3124 to descend slightly, so that the edge of the material tray C just falls on the upper surface of the support block 31222, and the support block 31222 supports the material tray C.

[0073] Finally, the lifting drive 3123 continues to drive the receiving tray 3124 to descend to a height that is coplanar with the bearing surface of the tray bracket 313, i.e., the initial height of the receiving surface of the second compartment 312A, in preparation to receive the next tray C. The stacked trays C are then firmly supported by the support block 31222 at a preset height within the second cavity 3121A.

[0074] Repeat the above steps, each newly fed material tray C is pushed from below to avoid the support block 31222, and after passing through, it is supported by the support block 31222 and stacked layer by layer on the already stacked material trays C.

[0075] It should be noted that the support component 3122 in this embodiment is suitable for supporting multiple empty trays C. That is, in the second workpiece loading mechanism 30, the first hopper 311 contains full trays C carrying the second workpiece B, and the second hopper 312 is used to receive empty trays C. During operation, the pusher component 314 pushes the trays C fully loaded with the second workpiece B from the first hopper 311 to the pick-and-place station 313A one by one, so that the second workpiece picking component 32, the second workpiece transferring component 34, or the operator can remove the second workpiece B from the tray C. After all the second workpieces B on the tray C have been removed, the pusher component 314 continues to push the empty tray C into the second hopper 312 for stacking and recycling.

[0076] This invention proposes an embodiment, see [link to embodiment]. Figure 6The support component 3122' includes a horizontal cylinder 31221' and a pusher 31222'. The pusher 31222' is located at the output end of the horizontal cylinder 31221'. The horizontal cylinder 31221' drives the pusher 31222' to reciprocate in the horizontal direction. The bearing surface of the pusher 31222' is coplanar with the bearing surface of the material tray bracket 313 to receive the material tray C pushed from the material pick-and-place station 313A to the second compartment 312A. The horizontal cylinder 31221' drives the pusher 31222' to extend and support the material tray C; the lifting drive 3123 is used to drive the receiving tray 3124 to rise to the height of the pusher 31222' after the pusher 31222' supports the material tray C; the horizontal cylinder 31221' drives the pusher 31222' to retract, and the material tray C loses its support and is supported by the receiving tray 3124 for stacking.

[0077] In this embodiment, the support component 3122′ of the second hopper 312 is used to support the tray C, thereby supporting a single tray C.

[0078] The support components 3122' consist of two sets, clamping the material tray C from opposite sides. Specifically, two sets of horizontal cylinders 31221' are fixedly installed on the equipment frame at corresponding positions on both sides of the second cavity 3121A. Two sets of push bars 31222' are connected to the output ends of the corresponding horizontal cylinders 31221', extending towards each other or retracting away from each other in the horizontal direction. When both sets of push bars 31222' extend simultaneously, they extend into the opposite sides of the material tray C from opposite sides, forming a symmetrical clamping of the material tray C. When both sets of push bars 31222' retract simultaneously, they are simultaneously pulled away from the sides of the material tray C, releasing the support for the material tray C.

[0079] The bearing surface of the pusher bar 31222' is coplanar with the bearing surface of the tray support 313, that is, coplanar with the bearing surfaces of the loading / unloading station 313A and the first compartment 311A, so as to receive the tray C pushed from the loading / unloading station 313A to the second compartment 312A. Through this coplanar arrangement, when the tray C is pushed to the second compartment 312A, it can smoothly transition from the tray support 313 to the two sets of pushers 31222' without creating steps or jamming.

[0080] In this embodiment, the stacking process of the second hopper 312 is as follows: Initially, in the initial state, the two sets of horizontal cylinders 31221' synchronously drive the corresponding pushers 31222' to extend, at which point the bearing surface of the pushers 31222' is coplanar with the bearing surface of the tray support 313. When the pusher assembly 314 pushes a single tray C from the loading / unloading station 313A to the second compartment 312A, the tray C enters the second cavity 3121A, and its bottom surface falls precisely on the upper surface of the two sets of pushers 31222', supported by the two sets of pushers 31222' from opposite sides. At this time, the lifting drive 3123 drives the receiving tray 3124 to a lower position, not in contact with the tray C.

[0081] Then, the lifting drive 3123 drives the receiving tray 3124 to rise to the height of the push bar 31222'. At this time, the upper surface of the receiving tray 3124 is close to or just in contact with the bottom surface of the tray C.

[0082] Secondly, the two sets of horizontal cylinders 31221' synchronously drive the corresponding pusher bars 31222' to retract, causing the two sets of pusher bars 31222' to be simultaneously pulled away from the side of the material tray C. After the material tray C loses the support of the pusher bars 31222', it is supported by the receiving tray 3124.

[0083] Finally, the lifting drive 3123 drives the receiving tray 3124 to descend a preset distance, i.e., one tray thickness, carrying the tray C, so that the upper surface of the tray C is lower than the bearing surface height of the pusher 31222', leaving space for receiving the next tray C. At the same time, the two sets of horizontal cylinders 31221' synchronously drive the pusher 31222' to extend and reset to a position coplanar with the bearing surface of the tray bracket 313, ready to receive the next tray C.

[0084] Repeat the above steps. In subsequent cycles, since there are already trays C stacked on the receiving tray 3124, the initial height of the receiving tray 3124 is gradually reduced, each time by one tray thickness, to ensure that the gap between the upper surface of the receiving tray 3124 and the bearing surface of the pusher 31222' remains unchanged each time a new tray C is received. When the preset number of layers has been stacked, the lifting drive 3123 can drive the receiving tray 3124 to continue to descend, and the entire stack of trays C is removed from the equipment by an external handling mechanism.

[0085] It should be noted that the support component 3122' in this embodiment is suitable for supporting a single full material tray C. That is, in the finished product unloading mechanism 60, empty material trays C are stacked in the first hopper 311, and the second hopper 312 is used to receive full material trays C that have been loaded with finished products. In other words, during operation, the pusher component 314 pushes the empty material trays C one by one from the first hopper 311 to the material handling station 313A. The finished product handling component 61 or a person places the qualified finished products into the empty material trays C. After the material tray C is full of finished products, the pusher component 314 continues to push the full material tray C into the second hopper 312 for stacking and recycling.

[0087] In this embodiment, the assembly mechanism 40 includes an assembly base 41, an assembly drive component 42, an assembly transmission component 43, and a pressing assembly 44.

[0088] This invention proposes an embodiment, see [link to embodiment]. Figure 1 , 2 14. The turntable 11 of the turntable mechanism 10 is also provided with a detection station 11D. The assembly unloading equipment 100 also includes a detection mechanism 50 corresponding to the detection station 11D. The detection mechanism 50 is used to perform quality inspection on the finished product to determine whether the finished product is qualified.

[0089] In this embodiment, the turntable 11 is further provided with a detection station 11D, and the detection station 11D is correspondingly provided with a support seat 12. The support seat 12 is fixedly mounted on the turntable 11 and rotates synchronously with the turntable 11. The detection station 11D is located after the assembly station 11C and is used to perform quality inspection on the assembled finished product formed by the first workpiece A and the second workpiece B, in order to determine whether the finished product is qualified. The support seat 12 has a receiving groove 12A for receiving and positioning the finished product.

[0090] This invention proposes an embodiment, see [link to embodiment]. Figure 1 , 14 The detection mechanism 50 includes a rotation unit 51, a placement unit 52, and a vision detection unit 53. The rotation unit 51 and the placement unit 52 are located adjacent to the detection station 11D. The placement unit 52 is located below the rotation unit 51 and is used to place and move the finished product. The vision detection unit 53 is located corresponding to the placement unit 52 and is used to perform image acquisition and quality detection on the finished product to determine whether the finished product is qualified. The rotation unit 51 includes a rotation base 511, a rotation horizontal movement component 512, a rotation vertical movement component 513, a rotary motor 514, and a gripper cylinder 515. The rotation base 511 is located corresponding to the detection station 11D. The rotation horizontal movement component 512 is fixed to the rotation base 511. The rotation vertical movement component 513 is fixed to the rotation horizontal movement component 512. The rotary motor 514 is fixed to the rotation vertical movement component 513. The gripper cylinder 515 is connected to the output end of the rotary motor 514.

[0091] In this embodiment, the inspection mechanism 50 includes a rotating unit 51, a placement unit 52, and a visual inspection unit 53. The rotating unit 51 and the placement unit 52 are located adjacent to the inspection station 11D and are used to remove the assembled finished product located on the inspection station 11D and transfer it to the inspection position. The placement unit 52 is located below the rotating unit 51 and is used to place and move the assembled workpiece to facilitate material retrieval in the next process. The visual inspection unit 53 is located corresponding to the placement unit 52 and is used to perform image acquisition and quality inspection on the finished product to determine whether the finished product is qualified.

[0092] Specifically, the placement unit 52 is fixedly installed on the frame of the assembly unloading equipment 100 and located directly below the rotating unit 51. The placement unit 52 includes a placement base 521 and a moving component 522. The placement base 521 is fixedly installed on the machine platform of the assembly unloading equipment 100, serving as the supporting foundation for the placement unit 52. A placement slot 521A is formed on the upper surface of the placement base 521, and its shape is adapted to the shape of the finished product for placing the assembled finished product. The moving component 522 is used to move the placement base 521 to realize the switching of the placement base 521 between different workstations. The moving component 522 includes a linear guide rail and a drive cylinder. The linear guide rail is fixedly installed on the machine base of the assembly unloading equipment 100. The placement seat 521 is slidably installed on the linear guide rail. The output end of the drive cylinder is connected to one side of the placement seat 521. The extension and retraction of the drive cylinder drives the placement seat 521 to reciprocate linearly along the linear guide rail, thereby allowing the placement seat 521 to switch between a receiving position and a discharge position. Further, when the placement seat 521 is in the receiving position, its placement groove 521A faces the lower output end of the rotating unit 51 to receive the assembled finished product transferred from the rotating unit 51. After the finished product is placed in the placement groove 521A, the moving component 522 drives the placement seat 521 to move to the discharge position, so that the robot or operator can easily pick up the finished product and enter the next cycle.

[0093] The rotating unit 51 includes a rotating base 511, a horizontal rotating component 512, a vertical rotating component 513, a rotary motor 514, and a gripper cylinder 515. The rotating base 511 is positioned corresponding to the detection station 11D and serves as the supporting foundation for the rotating unit 51, fixedly mounted on the frame of the assembly and unloading equipment 100. The horizontal rotating component 512 is fixedly mounted on the rotating base 511 and provides reciprocating linear motion in the horizontal direction. The vertical rotating component 513 is fixedly mounted on the output end of the horizontal rotating component 512 and moves synchronously in the horizontal direction with the output end of the horizontal rotating component 512, providing reciprocating linear motion in the vertical direction. The rotary motor 514 is fixedly mounted on the output end of the vertical rotating component 513 and moves synchronously up and down in the vertical direction with the vertical rotating component 513, providing rotational motion around an axis. The gripper cylinder 515 is connected to the output end of the rotary motor 514 and rotates synchronously with the output end of the rotary motor 514 to grip or release the assembled finished product.

[0094] Specifically, the rotating horizontal movement component 512 can be in the form of a rodless cylinder, a sliding cylinder, or a motor-driven lead screw module, etc. Its output end moves reciprocally in the horizontal direction, thereby driving the rotating vertical movement component 513, the rotary motor 514, and the gripper cylinder 515 to move reciprocally between the inspection station 11D and the placement unit 52. The rotating vertical movement component 513 can be in the form of a lifting cylinder or an electric cylinder, etc. Its output end moves up and down in the vertical direction, thereby driving the rotary motor 514 and the gripper cylinder 515 to move towards or away from the support seat 12 and the placement unit 52 to complete the material picking and unloading actions. The rotary motor 514 can be a stepper motor or a servo motor, and its output end rotates around the axis. It is used to adjust the angle of the assembled finished product during the transfer process so that the workpiece is placed in the placement slot 521A of the placement unit 52 in the correct posture, and to rotate the workpiece to different inspection positions in conjunction with the need for multi-angle image acquisition during the visual inspection process.

[0095] The visual inspection unit 53 is used to inspect the appearance and assembly quality of the assembled finished products placed on the placement unit 52. Specifically, the visual inspection unit 53 includes an industrial camera 531, a camera bracket 532, and a light source. The industrial camera 531 is fixedly mounted on the frame of the assembly unloading equipment 100 via the camera bracket 532, with its lens facing the placement slot 521A of the placement unit 52, for acquiring images of the assembled finished products. The light source is located near the industrial camera 531 or arranged around the placement unit 52 to provide uniform and stable lighting conditions for the inspection area, ensuring the clarity and contrast of the acquired images. The industrial camera 531 is electrically connected to an external control system, and the acquired image data is analyzed by an image processing algorithm to determine whether there are defects in the assembled finished products, such as whether the first workpiece A and the second workpiece B are assembled in place, whether the pressing depth meets the standard, and whether there are appearance defects such as scratches or cracks on the workpiece surface.

[0096] During inspection, when multi-angle appearance inspection of the assembled product is required, the vision inspection unit 53 first performs an initial image acquisition on the assembled product at the initial angle. After the first image acquisition, the rotary motor 514 drives the gripper cylinder 515 and the assembled product to rotate along the axial direction by a preset angle. The vision inspection unit 53 then performs a second image acquisition on the rotated assembled product. This process is repeated, with the rotary motor 514 rotating the assembled product sequentially to multiple inspection angles, such as 0°, 90°, 180°, 270°, or continuously rotating at a constant speed, according to a preset program. The vision inspection unit 53 triggers image acquisition at each angle to obtain complete circumferential or specific orientation appearance image data of the assembled product. The acquired multi-angle images are transmitted to the control system for comprehensive comparison and analysis to fully determine whether the assembled product has defects such as incomplete assembly, press-fit depth deviation, surface scratches, or cracks.

[0097] The working principle of the detection mechanism 50 is as follows: When the turntable 11 carrying the assembled finished product rotates to the inspection station 11D, the rotating horizontal movement component 512 drives the rotating vertical movement component 513, the rotary motor 514, and the gripper cylinder 515 to move horizontally above the support seat 12 of the inspection station 11D. The rotating vertical movement component 513 drives the rotary motor 514 and the gripper cylinder 515 to descend vertically to the preset material picking height, so that a pair of grippers are respectively located on both sides of the assembled finished product. The gripper cylinder 515 actuates, driving the pair of grippers to move closer together and clamp and fix the assembled finished product. The rotating vertical movement component 513 drives the gripper cylinder 515 to rise vertically, removing the assembled finished product from the receiving groove 12A of the support seat 12. The rotating horizontal movement component 512 drives the gripper cylinder 515 to move horizontally above the placement groove 521A of the placement unit 52.

[0098] Subsequently, the vision inspection unit 53 is activated, and the industrial camera 531, with the assistance of a light source, acquires images of the assembled product and transmits the image data to the control system for analysis and processing to determine whether the assembly quality is up to standard. During the inspection process, if multi-angle inspection of the assembled product is required, the rotary motor 514 will rotate to a set angle for secondary image acquisition, repeating this process until all inspection angles are completed.

[0099] After the inspection is completed, the rotating unit 51 operates again to transfer the inspected assembled product to the placement slot 521A of the placement seat 521 located directly below it. During this transfer process, if the clamping posture of the rotating unit 51 is inconsistent with the feeding direction of the placement slot 521A, the rotary motor 514 of the rotating unit 51 is activated, driving the gripper cylinder 515 and the assembled product to rotate by a preset angle, adjusting the workpiece to the correct posture to ensure that the finished product falls smoothly and accurately into the placement slot 521A.

[0100] After the finished product is placed into the placement slot 521A, the moving component 522 is activated, driving the placement seat 521 to move from the receiving position to the discharge position in a straight line. At this time, the control system of the assembly unloading equipment 100 performs an automatic sorting operation based on the detection results: If the test result is qualified, the finished product is temporarily stored at the discharge position and waits for the finished product unloading mechanism 60 to transfer it to the qualified product conveyor line to enter the next process. If the test result is a defective product, the finished product will wait at the discharge position for the defective product collection mechanism 70 to recycle it.

[0101] This invention proposes an embodiment, see [link to embodiment]. Figure 15The finished product unloading mechanism 60 also includes a finished product picking component 61, which is located adjacent to the detection station 11D. The finished product picking component 61 includes a finished product picking linear module 611, a servo motor 612, a lead screw, a sliding seat 613, a slide rail 614, a rack cylinder 615, a rack 616, a gear, and a picking cylinder 617. The finished product picking linear module 611 is horizontally positioned above the material tray bracket 313. The servo motor 612 is fixed to the sliding end of the finished product picking linear module 611, and the lead screw is connected to the output end of the servo motor 612 and extends vertically. The slide rail 615... 14 is fixed to the sliding end of the finished product picking linear module 611 and extends vertically; the sliding seat 613 is threaded to the lead screw and slidably mounted on the slide rail 614; the rack cylinder 615 is fixed to the sliding seat 613 and its output end extends vertically; the rack 616 is connected to the output end of the rack cylinder 615 and extends vertically; the gear is rotatably mounted on the sliding seat 613 and meshes with the rack 615; the picking cylinder 617 is fixed to the gear and is used to pick up or release the finished product.

[0102] In this embodiment, the finished product picking linear module 611 is horizontally positioned above the tray support 313 of the tray conveying assembly 30 of the finished product unloading mechanism 60, providing the finished product picking assembly 61 with a linear motion degree of freedom in the horizontal direction. The finished product picking linear module 611 can be a synchronous belt linear module, a lead screw linear module, or a linear motor module, and is fixedly mounted horizontally on the equipment frame, situated in the top region between the first tray 311 and the second tray 312 of the finished product unloading mechanism 60. The finished product picking linear module 611 includes a module body, a sliding end slidably mounted on the module body, and a drive motor that drives the sliding end to reciprocate along the module body.

[0103] The servo motor 612 is fixed to the sliding end of the finished product picking linear module 611 and moves synchronously with the sliding end in the horizontal direction. The output end of the servo motor 612 is connected to the lead screw. The lead screw extends vertically. One end of the lead screw is fixedly connected to the output shaft of the servo motor 612 via a coupling and rotates synchronously with the output shaft of the servo motor 612. The lead screw has an external thread that forms a threaded engagement with the internal thread of the sliding seat 613, thereby converting the rotational motion of the servo motor 612 into the linear lifting motion of the sliding seat 613.

[0104] The slide rail 615 is fixed to the sliding end of the finished product picking linear module 611 and extends vertically. The slide rail 614 is a linear guide or guide shaft, arranged parallel to the lead screw at intervals to prevent the sliding seat 613 from swaying or rotating during lifting.

[0105] The sliding seat 613 is threadedly connected to the lead screw, meaning that the sliding seat 613 has an internal threaded hole that matches the external thread of the lead screw, through which the lead screw passes and engages. Simultaneously, the sliding seat 613 is slidably mounted on the slide rail 614. When the servo motor 612 drives the lead screw to rotate, the sliding seat 613 rises and falls vertically along the slide rail 614 under the drive of the lead screw thread. Through the combination of the lead screw and the slide rail 614, the sliding seat 613 achieves smooth, precise, and high-load-bearing lifting motion, capable of supporting heavy material handling cylinders 617 and finished products.

[0106] The rack cylinder 615 is fixed to the sliding seat 613 and rises and falls synchronously with the sliding seat 613. The output end of the rack cylinder 615 extends and retracts in the vertical direction. The rack 616 is connected to the output end of the rack cylinder 615 and extends in the vertical direction, reciprocating in the vertical direction as the piston rod extends and retracts. The length of the rack 616 is set according to the required rotation angle range.

[0107] The gear is rotatably mounted on the sliding seat 613, for example, via a shaft and bearing, and meshes with the rack 616. The gear and rack 616 form a gear and rack transmission pair. When the rack 616 reciprocates in the vertical direction under the drive of the rack cylinder 615, the gear is driven by the rack 616 to rotate around its axis.

[0108] The picking cylinder 617 is fixed to the gear and is used to grip or release the finished product. Driven by the gear, the sliding seat 613, and the sliding end of the finished product picking linear module 611, the picking cylinder 617 achieves rotation, lifting, and horizontal movement, respectively. Through the linkage of the finished product picking linear module 611, the servo motor 612 in conjunction with the lead screw and the sliding seat 613, the rack cylinder 615 in conjunction with the rack 616 and the gear, and the picking cylinder 617, the picking cylinder 617 possesses flexible movement capabilities in three degrees of freedom: horizontal, vertical, and around a horizontal axis.

The vibration assembly 214 is fixedly installed at the bottom of the feeding pipe 213 and is used to drive the feeding pipe 213 to vibrate in order to transport the first workpiece A.

[0110] In this embodiment, the first workpiece loading mechanism 20 further includes a first workpiece feeding assembly 21, which is configured corresponding to the first workstation 11A and is used to transport the first workpiece A to the first workpiece sorting assembly 22. The first workpiece feeding assembly 21 includes a vibratory feeder 211, a guide pipe 212, a feeding pipe 213, and a vibration assembly 214.

[0111] This invention proposes an embodiment, see [link to embodiment]. Figure 3 The first workpiece feeding mechanism 20 further includes a first workpiece feeding assembly 21, which is set corresponding to the first workstation 11A and is used to transport the first workpiece A. The first workpiece feeding assembly 21 includes a vibratory feeder 211, a guide pipe 212, a feeding pipe 213, a vibration assembly 214, and a blocking assembly 215. The outlet of the vibratory feeder 211 is connected to one end of the guide pipe 212, and the other end of the guide pipe 212 is connected to the feeding pipe 213.

The vibration assembly 215 is fixedly installed at the bottom of the feeding pipe 213 and is used to drive the feeding pipe 213 to vibrate in order to transport the first workpiece A.

[0112] In this embodiment, the blocking component 215 is installed at the outlet of the feeding pipe 213 to prevent the material from being discharged from the feeding pipe 213 when the storage tank 221A is in the second position. Specifically, the blocking component 215 includes a blocking drive 2151 and a blocking component 2152. The blocking drive 2151 is fixedly installed on the outer wall of the feeding pipe 213 or on an adjacent mounting bracket, and its output end is connected to the blocking component 2152. Under the drive of the blocking drive 2151, the blocking component 2152 can move between a blocking position extending into the outlet channel of the feeding pipe 213 and a clearance position exiting the outlet channel. When the material distribution plate 2222 drives the storage seat 221 to switch to the second position, the blocking drive 2151 drives the blocking component 2152 to extend into the outlet channel of the feeding pipe 213, preventing the first workpiece A at the foremost end from continuing to move forward. When the material distribution plate 2222 drives the storage seat 221 to reset to the first position, the blocking drive member 2151 drives the blocking member 2152 to exit the outlet channel, so that the first workpiece A can smoothly enter the storage tank 221A under the action of vibration conveying.

[0113] This invention proposes an embodiment, see [link to embodiment]. Figure 3 The first workpiece loading mechanism 20 further includes a first workpiece picking component 23.

The positioning component 33 includes a positioning base 331, a positioning cylinder 332, a positioning plate 333, and a positioning block 334. The positioning base 331 is fixedly installed on the periphery of the equipment frame or turntable mechanism 10, serving as the supporting foundation for the positioning component 33. The positioning cylinder 332 is fixedly disposed on the positioning base 331, and its output end is connected to the positioning plate 333, used to drive the positioning plate 333 to reciprocate horizontally. The positioning block 334 is fixedly disposed on the positioning base 331 or the support seat 12 and forms a positioning groove 334A that matches the shape of the second workpiece B. The positioning plate 333 is located at the side opening of the positioning groove 334A and is disposed opposite to the positioning groove 334A. During operation, the second workpiece B is placed on the support seat 12 and located in the positioning groove 334A. The positioning cylinder 332 drives the positioning plate 333 to move towards the positioning groove 334A, which cooperates with the positioning groove 334A to clamp and position the second workpiece B, ensuring that the second workpiece B is in an accurate position and has a stable posture before assembly, and avoiding poor assembly due to position deviation.

[0117] This invention proposes an embodiment, see [link to embodiment]. Figure 11 The second workpiece feeding mechanism 30 further includes a second workpiece picking component 32, which is used to move the second workpiece B to the second station 11B. The second workpiece picking component 32 includes a second mounting base 321, a second transverse moving component 322, a second longitudinal moving component 323, a flipping component 324, and a gripping component 325. The second mounting base 321 is disposed adjacent to the second station 11B. The second transverse moving component 322 is fixedly mounted on the second mounting base 321. The second longitudinal moving component 323 is fixedly mounted on the output end of the second transverse moving component 322. The flipping component 324 is drivenly connected to the output end of the second longitudinal moving component 323. The gripping component 325 is fixedly mounted on the flipping component 324.

[0118] In this embodiment, the second workpiece loading mechanism 30 further includes a second workpiece picking assembly 32, used to move the second workpiece B to the second station 11B. The second workpiece picking assembly 32 includes a second mounting base 321, a second lateral movement assembly 322, a second longitudinal movement assembly 323, a flipping assembly 324, and a gripping assembly 325. The second mounting base 321 is disposed adjacent to the second station 11B, providing support for the entire picking assembly. The second lateral movement assembly 322 is fixed to the second mounting base 321, used to drive each component to move horizontally between the positioning groove 334A of the positioning assembly 33 and the second station 11B. The second longitudinal movement assembly 323 is fixed to the output end of the second lateral movement assembly 322, used to drive the flipping assembly 324 and the gripping assembly 325 to rise and fall. The flipping assembly 324 is drively connected to the output end of the second longitudinal movement assembly 323, used to drive the gripping assembly 325 to flip around the horizontal axis to adjust the posture of the second workpiece B. The gripping assembly 325 is fixed to the output end of the flipping assembly 324, used to grip or release the second workpiece B. During operation, the second lateral moving component 322 and the second longitudinal moving component 323 work together to drive the gripping component 325 to reciprocate between the positioning slot 334A of the positioning component 33 and the second station 11B. The flipping component 324 adjusts the posture of the second workpiece B as needed during the transfer process, thereby transferring the second workpiece B in a preset posture. Alternatively, the second workpiece picking component 32 can directly transfer the second workpiece B, which is located at the picking / placing station 313A, to the second station 11B.

[0119] This invention proposes an embodiment, see [link to embodiment]. Figure 4-7 The second workpiece loading mechanism 30 further includes a second workpiece transfer assembly 34, which is used to move the second workpiece B. The second workpiece transfer assembly 34 includes a transfer linear module 341, a lifting slide cylinder 342, a rotary cylinder 343, and a clamping cylinder 344. The transfer linear module 341 is arranged horizontally above the material tray bracket 313. The lifting slide cylinder 342 is slidably mounted on the transfer linear module 341, and the output end of the lifting slide cylinder 342 extends and retracts vertically. The rotary cylinder 343 is fixed to the output end of the lifting slide cylinder 342. The clamping cylinder 344 is fixed to the output end of the rotary cylinder 343 and is used to clamp or release the second workpiece B.

[0120] In this embodiment, the second workpiece transfer assembly 34 is used to remove the second workpiece B located at the pick-and-place station 313A from the material tray C and transfer it to the positioning slot 334A of the positioning assembly 33 for positioning. The transfer linear module 341 provides linear motion in the horizontal direction, driving the clamping cylinder 344 to reciprocate between the pick-and-place station 313A and the positioning assembly 33. The lifting slide cylinder 342 drives the clamping cylinder 344 to rise and fall to realize the pick-and-place action. The rotary cylinder 343 is used to adjust the horizontal angle and posture of the second workpiece B during the transfer process to ensure that the second workpiece B is placed in the positioning slot 334A in the correct direction. The clamping cylinder 344 is used to clamp or release the second workpiece B, and its jaw end can be set with a contour clamping block according to the shape of the second workpiece B to improve clamping stability.

[0121] When the assembly unloading equipment 100 has a positioning component 33, the second workpiece B, located at the pick-and-place station 313A, is moved to the positioning slot 334A of the positioning component 33 for positioning by setting a second workpiece transfer component 34. The specific workflow is as follows: the transfer linear module 341 drives the clamping cylinder 344 to move above the pick-and-place station 313A; the lifting slide cylinder 342 drives the clamping cylinder 344 to descend, clamp the second workpiece B, and then rises. The transfer linear module 341 then moves the second workpiece B above the positioning slot 334A of the positioning component 33. The rotary cylinder 343 adjusts the angle as needed, and the lifting slide cylinder 342 drives the clamping cylinder 344 to descend, placing the second workpiece B into the positioning slot 334A. The clamping cylinder 344 then releases the second workpiece B and exits. Subsequently, the positioning component 33 positions and clamps the second workpiece B for use in subsequent assembly processes.

[0122] The workflow of this invention is as follows: 1. Loading the first workpiece A The first workpiece A is conveyed to the first workpiece distribution assembly 22 via the vibratory feeder 211, guide pipe 212, and feeding pipe 213. The distribution plate 2222 moves back and forth, causing the storage seat 221 to switch between receiving and stopping states, so that each first workpiece A enters the storage tank 221A one by one. The suction assembly 234 of the first workpiece picking assembly 23 picks up the first workpiece A in the storage tank 221A and transfers it to the support seat 12 of the first station 11A of the turntable 11.

[0123] 2. Loading the second workpiece B The second workpiece loading mechanism 30 is activated, and the trays C, fully loaded with the second workpiece B, stacked in the first hopper 311, fall sequentially to the first hopper position 311A. The pusher drive 3144 drives the moving seat 3142 to move towards the second hopper 312 via the pusher transmission 3143. The pushing surface 31411 of the pusher claw 3141 pushes against the side of the bottom tray C, pushing it from the first hopper position 311A ​​to the pick-and-place station 313A.

[0124] The second workpiece transfer component 34 is activated. The transfer linear module 341 drives the clamping cylinder 344 to move above the pick-and-place station 313A. The lifting slide cylinder 342 drives the clamping cylinder 344 to descend, clamp the second workpiece B, and then rise. The transfer linear module 341 then transfers the second workpiece B to the positioning groove 334A above the positioning component 33. The rotary cylinder 343 adjusts the angle as needed. The lifting slide cylinder 342 drives the clamping cylinder 344 to descend and place the second workpiece B into the positioning groove 334A. The clamping cylinder 344 releases the second workpiece B and then exits.

[0125] Positioning cylinder 332 drives positioning plate 333 to move towards positioning groove 334A, cooperating with positioning groove 334A to clamp and position the second workpiece B, ensuring accurate positioning and stable attitude of the second workpiece B. After positioning is completed, positioning cylinder 332 drives positioning plate 333 to retract and release.

[0126] When the second workpiece picking component 32 is activated, the second lateral moving component 322 and the second longitudinal moving component 323 work together to drive the gripping component 325 to move above the positioning slot 334A of the positioning component 33 and descend to grip the second workpiece B. After gripping, the flipping component 324 drives the gripping component 325 to flip by a preset angle according to process requirements, adjusts the second workpiece B to the correct posture, and then transfers it to the support seat 12 of the second station 11B.

[0127] After the material is retrieved, the pusher assembly 314 continues to push the empty material tray C into the second hopper 312 for recycling, while the next full material tray C falls into the first hopper 311A ​​and enters the next cycle.

[0128] 3. Turntable rotation and assembly The turntable drive assembly 13 drives the turntable 11 to rotate intermittently, moving the support seat 12 carrying the first workpiece A and the second workpiece B from the first station 11A and the second station 11B to the assembly station 11C. The buffer cylinder 141 of the buffer assembly 14 extends, and the buffer pad 142 abuts against the back of the turntable 11 to provide support. The assembly drive component 42 drives the pressing assembly 44 to press down, and the pressing head 446 presses the first workpiece A into the second workpiece B, completing the assembly to form the finished product.

[0129] 4. Detection and triage Turntable 11 continues to rotate, delivering the finished product to inspection station 11D. The gripper cylinder 515 of rotating unit 51 picks up the finished product and rotates it. The vision inspection unit 53 captures images and performs quality checks on the finished product from different angles. After inspection, the gripper cylinder 515 transfers the finished product to the placement slot 521A of placement unit 52, and then the moving component 522 moves the placement seat 521 to the discharge position.

[0130] If the test result is qualified, the finished product picking component 61 will take the finished product from the discharge position of the placement unit 52 and transfer it to the picking and placing station 313A of the finished product unloading mechanism 60, and place it into the empty material tray C. The material tray C full of finished products is pushed by the pusher assembly 314 into the second material bin 312 for stacking and recycling.

[0131] If the test result is a defective product, the finished product picking component 61 will take the defective product from the discharge position of the placement unit 52 and transport it to the synchronous belt 74 of the defective product collection mechanism 70.

[0132] 5. Finished product unloading Empty trays C in the first hopper 311 fall sequentially to the first hopper position 311A, where the pusher assembly 314 pushes them to the pick-and-place station 313A. The finished product picking assembly 61 removes qualified finished products from the placement unit 52, and through the horizontal movement of the finished product picking linear module 611, the lifting of the lead screw, and the rotation of the gear driven by the rack and pinion cylinder 615, places them correctly into the empty tray C at the pick-and-place station 313A of the finished product unloading mechanism 60's tray conveying assembly 31. When tray C is full, the pusher assembly 314 of the finished product unloading mechanism 60's tray conveying assembly 31 pushes it to the second hopper position 312A, entering the second hopper 312. The lifting drive 3123 drives the receiving tray 3124 to rise, stacking the full trays C layer by layer in the second hopper 312. After the full trays C are stacked to a preset number of layers, they are removed by an external handling mechanism, realizing an automated cycle of finished product unloading.
