Technical Field
[0001] This utility model belongs to the field of automatic assembly, and specifically relates to an automatic assembly device for box bodies. Background Technology
[0002] As an indispensable packaging medium for industries such as cosmetics, electronics, food, and luxury goods, boxes come in a wide variety of types and increasingly complex structures (such as small bags, drawer boxes, and folding storage boxes). In modern industrial production, the manufacture of boxes typically involves the precision assembly of multiple independent components, such as top and bottom lids, magnets, hinges, and labels.
[0003] Traditional box assembly processes rely heavily on manual labor for material handling, alignment, and pressing. This labor-intensive method not only results in high labor intensity and costs for workers, but also significantly limits production efficiency due to worker skill levels and physical limitations. It fails to meet the urgent demands of modern manufacturing for large-scale, standardized production. Furthermore, the inherent subjectivity and instability of manual operation lead to inconsistent assembly precision and compromised yield rates. In addition, existing material supply mechanisms often employ fixed silo structures, which struggle to balance ease of loading with supply stability. Specifically, during batch replenishment, components are prone to interference with the silo walls, causing tipping and further complicating loading and reducing efficiency. Utility Model Content

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] (1) The automatic assembly equipment for box body of this utility model realizes the continuous and automated operation process of parts from positioning, gripping and adjustment to final assembly by combining multiple workstations and a movable gripping mechanism. In particular, the intermediate workstation can perform secondary position adjustment of parts, which effectively solves the problem that a single gripping action is difficult to meet the requirements of complex assembly angles and ensures the assembly accuracy of the box body. In addition, the material storage block can switch between open and closed states, which not only facilitates batch feeding, but also prevents jamming by limiting the lateral displacement of parts, further ensuring the stability and reliability of material supply, and also providing a guarantee for the smoothness and accuracy of subsequent assembly operations.
[0017] (2) The transmission method of motor and transmission rod can achieve more precise stroke control and speed adjustment, making the material support block more gentle in the process of lifting the parts to the top of the storage block, avoiding damage to precision parts due to excessive impact force; at the same time, the belt drive has a certain buffering and shock absorption effect, reducing the noise of the equipment operation.
[0018] (3) By using the locking cylinder to drive the locking shaft to insert into the locking hole, the rotating baffle can be stably locked in the closed state, which effectively prevents the rotating baffle from being accidentally loosened or popped open due to mechanical vibration when the material support block lifts the parts, thereby avoiding the risk of parts falling or material supply failure, and ensuring the continuous and stable operation of the automated production line.

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0022] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment 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 indicator will also change accordingly.
[0023] It should be noted that, in this embodiment, the multiple components assembled into the box mainly consist of an upper cover 10, a lower cover 11, a magnet 12, a hinge 14, and a label 13. (Refer to...) Figures 7 to 9As shown, the upper cover 10 and the lower cover 11 can be hinged together by hinge 14 to achieve relative rotation between the upper cover 10 and the lower cover 11. In order to maintain the stability of the upper cover 10 and the lower cover 11 after they are closed, this solution installs magnets 12 on the inner walls of the upper cover 10 and the lower cover 11. The magnetic attraction is used to ensure that the box will not open during carrying or transportation. In addition, the label 13 is attached to the outside of the box, so that each product can be identified and monitored.
[0024] like Figures 1 to 9 As shown, this utility model discloses an automatic assembly equipment for box bodies, including a machine base 2 and a gripping mechanism 3, a positioning station 20, a transfer station 21, an assembly station 22, and a feeding mechanism 4 disposed on the machine base 2.
[0025] The gripping mechanism 3 can grip and transfer multiple parts for assembly into a box. The positioning station 20, the transfer station 21, and the assembly station 22 are arranged at intervals along a preset path on the machine base 2. The positioning station 20 is used to accommodate parts. The transfer station 21 can clamp parts so that the gripping mechanism 3 can adjust its gripping position on the parts. The assembly station 22 is used to assemble multiple parts into one piece. The feeding mechanism 4 includes a transfer platform 40, a storage block 41, and a support block 42. The transfer platform 40 is used to move the storage block 41 closer to or away from the assembly station 22. The storage block 41 has an open state and a closed state. In the open state, multiple identical parts are placed inside it. In the closed state, it is used to limit the lateral displacement of the parts. The support block 42 passes through the transfer platform 40 vertically and extends into the storage block 41 to lift the parts to the top of the storage block 41.
[0026] The assembly equipment in this solution is located on one side of an external injection molding machine, which is not shown in the figure. Therefore, after the injection molding machine forms the upper cover 10 or lower cover 11, the parts inside the injection molding machine can be picked up by the gripping mechanism 3 and transferred to the assembly equipment. It is worth noting that the label 13 and hinge 14 in the above-mentioned parts can be continuously fed by the feeding mechanism 4. The positioning station 20, transfer station 21 and assembly station 22, which are arranged at intervals along the preset path, form a standardized and streamlined parts transfer and assembly link. Among them, the positioning station 20 can realize the initial orderly placement of parts, ensure the uniformity of the label 13 pasting position, and thus avoid the parts being misplaced. To mitigate assembly errors, the components in this embodiment typically refer to the upper cover 10 or the lower cover 11. The intermediate station 21 has the function of clamping components, providing stable support for the gripping mechanism 3 to adjust its gripping position secondary, solving the problems of insufficient single-grab positioning accuracy and gripping posture deviation, and significantly improving the tolerance rate of subsequent precise assembly. Simultaneously, the feeding mechanism 4 achieves station switching of the storage block 41 through the transfer table 40. The switching of the opening and closing states of the storage block 41 enables batch storage and lateral positioning of components. With the coordinated vertical support of the material support block 42, orderly, continuous, and stable automatic feeding of components can be achieved, preventing component stacking offsets or even jamming. Therefore, this automatic assembly equipment has a high degree of overall structural integration and tight process connections, significantly reducing manual intervention costs, significantly improving the automation level, production efficiency, and assembly consistency of box assembly, and effectively reducing the product defect rate caused by manual assembly.
[0027] The gripping mechanism 3 includes: a robotic arm 30, with a drive member 31 movably hinged to the end of the robotic arm 30; a rotating bracket 32 and a gripping cylinder 33. The rotating bracket 32 is connected to the output end of the drive member 31, and the gripping cylinder 33 is mounted on the rotating bracket 32. A moving block 34 is connected to the output end of the gripping cylinder 33. Suction cups 35 for gripping parts are detachably connected to both the moving block 34 and the rotating bracket 32.
[0028] like Figure 1 and Figure 2 As shown, two robotic arms 30 are provided in this embodiment. Preferably, these robotic arms are six-axis robotic hands. Figure 1 The robotic arm 30 on the left mainly picks up the upper cover 10 and lower cover 11 from the external injection molding machine and places them into the positioning station 20. It then attaches the label 13 from the storage block 41 to the outer wall of the upper cover 10. Finally, the intermediate station 21 is used to transition the position of the suction cup 35 gripping the upper cover 10 or lower cover 11; that is, the suction cup 35 changes from adsorbing the outer wall of the part to be assembled to adsorbing the inner wall of the part to be assembled, facilitating subsequent assembly operations. Figure 1The robotic arm 30 on the right is mainly used to assemble the magnet 12 inside the upper cover 10 and the lower cover 11, and to transfer the upper cover 10 and the lower cover 11 to the assembly station 22 in sequence, where they are assembled together by adsorbing the hinge 14 through the suction cup 35. Specifically, through the coordinated operation of the robotic arm 30, the drive component 31, the rotating bracket 32 and the gripping cylinder 33, a high-precision and highly flexible material gripping and transfer system is constructed. Specifically, the drive component 31, which is hinged at the end of the robotic arm 30, is preferably a rotary motor or a rotary cylinder. The drive component 31 can drive the rotating bracket 32 to achieve multi-angle rotation adjustment, thereby adapting to the gripping needs of different placement angles or different assembly postures of the parts, and meeting the process requirements of multi-directional assembly of the box. Meanwhile, detachable suction cups 35 are installed on the moving block 34 connecting the rotating bracket 32 and the gripping cylinder 33. The double suction cups 35 working together increase the gripping force area of the parts, improve the stability of gripping and holding, and effectively avoid the problems of slippage, falling off, and displacement of parts during the transfer process. Furthermore, the suction cups 35, through bolts or threads and other detachable structural designs, can be flexibly replaced according to the size, shape, and material of the parts, without the need to replace the entire gripping mechanism 3, greatly improving the versatility and adaptability of the equipment. This also facilitates the replacement and maintenance of the suction cups 35 after wear, ensuring the long-term high-precision and stable operation of the gripping mechanism 3. It is worth noting that, for reference... Figure 2 As shown in the structure, there is a certain gap between the moving block 34 and the suction cups 35 on the rotating bracket 32, ensuring that the suction cups 35 at different positions will not interfere with each other during the gripping action.
[0029] The storage block 41 includes a fixed baffle 410 and a rotating baffle 411. The rotating baffle 411 is movably hinged to the fixed baffle 410 and together they form a storage cavity 412a.
[0030] In this embodiment, the opening and closing of the storage cavity 412a can be quickly achieved by the hinged rotation of the rotating baffle 411, such as... Figure 4 As shown, the storage cavity 412a in the open state has its side space completely open, which facilitates the batch loading, replenishment, or material cleaning of parts by robotic arms or operators, greatly improving the convenience of loading operations; such as Figure 5 As shown, in the closed state, it can cooperate with the fixed baffle 410 to form a limiting space for the label 13 or hinge 14. This not only precisely limits the lateral displacement of the parts but also ensures that all parts are neatly arranged during the storage process, providing a stable guarantee for subsequent assembly accuracy. Therefore, this hinged opening and closing structure is simple in structure, reliable in operation, and has a low failure rate. It can achieve the switching of storage function without a complex transmission structure, which not only ensures the stability of the material supply but also reduces the manufacturing and maintenance costs of the equipment. Compared with an integrated fixed storage structure, it has greater flexibility and adaptability in use.
[0031] The feeding mechanism 4 also includes a material transfer rail 43, a material transfer table 40 connected to the output end of the material transfer rail 43, a fixed baffle 410 detachably connected to the material transfer table 40, and a rotating baffle 411 that can rotate relative to the material transfer table 40 to open and close the storage cavity 412a.
[0032] like Figure 1 , Figure 4 as well as Figure 5 As shown, in this embodiment, the material storage block 41 reciprocates between the two ends of the material transfer rail 43 through the coordinated operation of the material transfer rail 43 and the material transfer table 40. Specifically, one end of the material transfer rail 43 is close to the robotic arm 30 so that the material storage block 41 is positioned... Figure 5 When positioned close to the robotic arm 30, it facilitates the gripping operation of the suction cup 35, while the transfer table 40 moves the storage block 41 to... Figure 4 When positioned away from the robotic arm 30 and close to the edge of the machine platform 2, the opening of the rotating baffle 411 facilitates the stacking and placement of labels 13 or hinges 14 by operators or robotic arms, thus providing a safe loading environment. Therefore, this linear guide drive offers advantages such as smooth operation, high positioning accuracy, and low frictional resistance. It can precisely and smoothly move the transfer platform 40 and the storage block 41 above it closer to or away from the assembly station 22, ensuring the accuracy of the feeding position and avoiding problems such as feeding misalignment and assembly failure caused by displacement deviation. Simultaneously, the fixed baffle 410 and the transfer platform 40 are detachably assembled using screws and other connecting components, and the rotating baffle 411 can rotate independently relative to the transfer platform 40. This design facilitates subsequent maintenance and makes the opening and closing control of the storage cavity 412a more precise and flexible, with faster action response, effectively matching the operating rhythm of the automated production line and further improving the overall operating efficiency and stability of the equipment.
[0033] The transfer table 40 is also equipped with a locking cylinder 400. The output end of the locking cylinder 400 is connected to a locking shaft 400a. The outer wall of the rotating baffle 411 is provided with a locking block 413. A locking hole 413a is opened in the locking block 413. The locking shaft 400a is movably inserted into the locking hole 413a.
[0034] like Figure 4 and Figure 5 As shown, as the labels 13 or hinges 14 to be assembled are stacked in the storage cavity 412a, the rotating baffle 411 rotates relative to the fixed baffle 410 to... Figure 5In the closed state shown, during this process, the locking block 413 rotates synchronously with the rotating baffle 411. When the storage cavity 412a is in the closed state, the locking hole 413a on the locking block 413 is exactly aligned with the locking shaft 400a. As the locking cylinder 400 drives the locking shaft 400a to move towards the locking block 413, the locking shaft 400a can be accurately inserted into the locking hole 413a, realizing the mechanical locking and positioning of the rotating baffle 411 in the closed state. Compared with the simple hinge structure limiting method, this structure effectively eliminates problems such as loosening and slight opening of the rotating baffle 411 caused by vibration, material extrusion, and inertial force during equipment operation. It ensures the structural stability of the storage cavity 412a after it is closed, continuously and stably restricts the lateral displacement of the parts, ensures that the parts in the storage cavity are always arranged in a regular and orderly manner, greatly improves the operational reliability of the feeding mechanism 4, reduces feeding failures and assembly defects caused by baffle loosening, and improves the product qualification rate.
[0035] The feeding mechanism 4 also includes: a mounting frame 44, which is set inside the machine base 2; a lead screw support 45 and a drive motor 46, both of which are set on the mounting frame 44. A transmission rod 450 is arranged inside the lead screw support 45, and the output shaft of the drive motor 46 is connected to the transmission rod 450 by a belt drive; a lifting platform 47, which is movably connected to the transmission rod 450 and can reciprocate along the axis of the transmission rod 450. A fixed column 470 is installed on the lifting platform 47, and the material support block 42 is connected to the top of the fixed column 470.
[0036] like Figure 2 and Figure 5 As shown, since the robotic arm 30 will grab the topmost label 13 or hinge 14 in the storage cavity 412a each time it drives the suction cup 35, the material support block 42 needs to lift the label 13 or hinge 14 in the storage cavity 412a from bottom to top after the suction cup 35 completes one grabbing action, so as to facilitate the stable grabbing operation of the suction cup 35 in the subsequent operation. Specifically, as shown... Figure 5 As shown, in this embodiment, the driving component 31 is preferably a stepper motor or a servo motor. A driving wheel is connected to the output shaft of the driving component 31, and a driven wheel is connected to the bottom end of the transmission rod 450. The driving wheel and the driven wheel are driven by a belt, thereby enabling the transmission rod 450 to rotate around its axis within the mounting frame 44. It should be noted that the transmission rod 450 and the lifting platform 47 are connected by a threaded connection. That is, the mating structure of the transmission rod 450 and the lifting platform 47 is the same as the structure and working principle of a ball screw in the prior art, which will not be elaborated further here. Therefore, when the transmission rod 450 rotates, it can drive the lifting platform 47 along... Figure 5The material support block 42 rises or falls by reciprocating in height and finally through the fixed column 470. This transmission method is stable and has low noise. The motor control can achieve precise stroke and speed adjustment to ensure that the parts are smoothly lifted to the top of the storage cavity 412a and avoid impact or misalignment. At the same time, the belt drive has a certain buffering effect, which helps to protect the motor and transmission components and improve the durability of the system.
[0037] Preferably, such as Figure 4 As shown, this embodiment also provides a guide hole 401 on the transfer platform 40. The guide hole 401 is located below the storage cavity 412a. It should be noted that the guide hole 401 is smaller than the size of the storage cavity 412a, that is, the label 13 or hinge 14 located in the storage cavity 412a will not detach from the guide hole 401 and go outside the transfer platform 40. During the lifting process of the support block 42, the support block 42 can pass through the guide hole 401 and then stably extend into the storage cavity 412a under the guidance and limiting effect of the guide hole 401, ensuring the smoothness and stability of the support block 42 when lifting the label 13 or hinge 14.
[0038] The positioning station 20 includes: a mounting table 200, which is detachably connected to the machine base 2; and several positioning blocks 201, which are symmetrically distributed on the mounting table 200. Each positioning block 201 has a positioning arc surface 201a, and the parts to be assembled abut against the positioning arc surface 201a.
[0039] like Figure 1 and Figure 3 As shown, after the upper cover 10 is formed by the external injection molding machine, the robotic arm 30 can use the suction cup 35 to grab the upper cover 10 and transfer it to the positioning station 20. During the placement of the upper cover 10, the symmetrically arranged positioning blocks 201 can limit the four corners of the upper cover 10 respectively. With the positioning arc surface 201a, it can accurately fit with the outer wall of the part. Compared with the planar positioning structure, the arc surface positioning can adapt to the parts with circular, arc, and irregular outer walls. The positioning fit is higher and the limiting effect is better. It can effectively limit the horizontal displacement and angular deviation of the parts and ensure that the initial placement posture and position height of all parts to be assembled are uniform. In addition, the mounting platform 200 is detachably assembled onto the machine base 2 via connecting components such as screws and bolts. This facilitates the quick replacement of the matching positioning block 201 with different specifications of parts without having to replace the entire workstation structure. This greatly improves the adaptability and debugging convenience of the equipment, ensuring the positioning accuracy of materials from the initial assembly station. This lays the foundation for precise operation of subsequent gripping, transfer, and assembly processes, effectively reducing assembly errors and improving product assembly consistency.
[0040] The intermediate station 21 includes: a fixed platform 210, which is detachably assembled on the machine base 2 by screws, bolts and other connecting parts; a contouring seat 211 and a limiting cylinder 212, which are symmetrically arranged on the fixed platform 210. The limiting cylinder 212 is located on the outer wall of the contouring seat 211, and a limiting block 213 is connected to the output end of the limiting cylinder 212. The limiting block 213 movably abuts against the outer wall of the part; and a clamping cylinder 214, which is arranged on the side wall of the fixed platform 210. The output end of the clamping cylinder 214 is connected to a clamping arm 215, which is used to clamp the part.
[0041] like Figure 6 As shown, this embodiment achieves high-precision and high-stability positioning and fixing of parts during transfer through a dual clamping and limiting structure consisting of a contouring base 211, a limiting cylinder 212, a limiting block 213, a clamping cylinder 214, and a clamping arm 215. Specifically, the contouring base 211 can be matched with parts, as shown in the reference. Figure 5 The upper cover 10 or lower cover 11 shown transforms the horizontally placed upper cover 10 or lower cover 11 into a vertical position, facilitating the change of the gripping position of the suction cup 35 on the robotic arm 30. This ensures that the shape can achieve basic support and contour-following limitation, initially fixing the placement posture of the parts. In addition, the limiting cylinder 212 drives the limiting block 213 to fit against the outer wall of the upper cover 10 or lower cover 11, achieving precise lateral limitation and preventing the parts from shifting left or right, which would affect the accuracy of the suction cup 35's gripping. It can be seen that, with the cooperation of multiple limiting and clamping structures, this structure effectively avoids problems such as shaking or displacement of the upper cover 10 or lower cover 11 when the suction cup 35 adjusts the gripping position, providing a stable working foundation for the gripping mechanism 3 to accurately adjust the gripping point and correct the gripping posture, and significantly improving the gripping position calibration accuracy. At the same time, the detachable structure design of the fixed table 210 facilitates equipment maintenance, debugging, and parts replacement, and can adapt to the transfer and positioning needs of various specifications of parts, effectively improving the operating accuracy and versatility of the equipment.
[0042] Furthermore, since the magnets 12 inside the upper cover 10 and the lower cover 11 are assembled in opposite directions, that is, the magnets 12 need to attract each other to ensure that the box remains closed. For this purpose, the magnets 12 adsorbed by the suction cup 35 are pre-placed between the two clamping arms 215. After the clamping cylinder 214 drives the clamping arms 215 to complete the clamping and fixing of the magnets 12, the robotic arm 30 can drive the suction cup 35 to adsorb from the other side of the magnets 12, so as to assemble the magnets 12 with different adsorbed sides into the upper cover 10 and the lower cover 11 respectively.
[0043] This solution also includes: a drive rail 50, mounted on the machine base 2; a drive block 51, connected to the movable end of the drive rail 50, the drive block 51 having a pusher groove 510, and the machine base 2 having a stepped groove 23, the pusher groove 510 movably abutting against the parts to push the parts to slide within the stepped groove 23; a placement block 52, the machine base 2 having an assembly seat 24 detachably connected to it, the placement block 52 being mounted on the assembly seat 24 and forming a placement channel 520 for accommodating parts; and a pusher cylinder 53, mounted on the machine base 2, the output end of the pusher cylinder 53 being connected to a pusher block, the pusher block being used to push the parts below the placement channel 520 into the stepped groove 23.
[0044] like Figure 9 As shown, workers or robots can pre-place several magnets 12 sequentially into the material placement channel 520. The material placement channel 520 allows for the orderly storage and guiding of multiple magnets 12, ensuring uniform output posture of the parts. Since the magnet 12 at the bottom will detach from the material placement channel 520 and fall onto one side of the pusher block, the pusher block is moved by the pusher cylinder 53, pushing the magnet 12 into the stepped groove 23. At this time, the drive rail 50 can drive the drive block 51 to move laterally along its direction. During this process, the pusher groove 510 is precisely against the two adjacent surfaces of the top and side walls of the magnet 12. Combined with the stable positioning and guiding function of the stepped groove 23, this ensures that the drive block 51 stably pushes the magnet 12 from the material placement channel 520. Figure 9 The magnet 12 is moved from the left to the far right, closer to the robotic arm 30, for easy gripping by the suction cup 35. This structure achieves fully automated operation of the magnet 12 from storage, pushing, and transfer, with smooth process connections, effectively improving material conveying efficiency and accuracy. It is suitable for high-speed automated assembly lines. Furthermore, the modular assembly base 24 and the detachable material block 52 facilitate the feeding needs of different sized parts, enhancing the equipment's versatility.
[0045] Preferably, in this embodiment, an auxiliary cylinder 25 may also be provided on the machine base 2, and an auxiliary block 250 is connected to the output end of the auxiliary cylinder 25, such as... Figure 3 As shown, during the assembly of the magnet 12, this solution can add the auxiliary cylinder 25 and the auxiliary block 250 to the positioning block 201 to facilitate the initial assembly of the magnet 12 with the upper cover 10 and the lower cover 11. Specifically, since the inner walls of the upper cover 10 and the lower cover 11 are provided with mounting grooves 100 for accommodating the magnet 12, the drive block 51 pushes the magnet 12 to be assembled into the mounting groove. Figure 9When the magnet 12 is at the rightmost end of the stepped groove 23 shown, the robotic arm 30 can drive the suction cup 35 to grasp it. Before assembly, the auxiliary cylinder 25 drives the auxiliary block 250 to press against the outer wall of the upper cover 10 or the lower cover 11. It is worth noting that the position of the auxiliary block 250 pressing against the outer wall is aligned with the mounting groove 100, which effectively prevents the magnet 12 from being deformed by squeezing the side wall of the upper cover 10 or the lower cover 11 when it is assembled into the mounting groove 100, thus ensuring the smoothness and stability of the assembly process.
[0046] Assembly station 22 includes: a base 220, detachably connected to the machine base 2; a movable plate 221, on which fixed bases 222 and abutment cylinders 223 are symmetrically arranged, the fixed bases 222 are used to support parts, and the output end of the abutment cylinders 223 is connected to a stop block 224 for pressing against the outer wall of the parts; a positioning block 225, movably mounted on the base 220, for moving and pressing against the outer wall of the parts; a transfer cylinder 226 and a slide rail 227, both set on the base 220, the output end of the transfer cylinder 226 is connected to the movable plate 221, and the bottom wall of the movable plate 221 is provided with a slider 228, which is movably engaged with the slide rail 227.
[0047] like Figure 7 and Figure 8 As shown, the robotic arm 30 uses a suction cup 35 to pre-place the upper cover 10, which is equipped with a label 13 and a magnet 12, into the fixed base 222. Through the coordinated action of the fixed base 222 and the positioning block 225 on the base 220, the upper cover 10 is initially positioned. (Refer to...) Figure 7 As shown in the structure, with the material-stopping cylinders 223 on both sides driving the stop blocks 224 to abut against the outer wall of the upper cover 10, the upper cover 10 can be securely placed in the fixed base 222 of the base 220. Similarly, before the robotic arm 30 places the lower cover 11 into the fixed base 222 on the moving plate 221 using the suction cup 35, the material-moving cylinder 226 moves the moving plate 221 away from the positioning block 225, so that the fixed base 222 on the moving plate 221 and the fixed base 222 on the base 220 are aligned. A certain gap is formed between them to ensure that the lower cover 11 on the suction cup 35 is stably placed in the fixed base 222 on the moving plate 221. After the material-stopping cylinder 223 on the moving plate 221 fixes the lower cover 11 on the moving plate 221, the material-moving cylinder 226 can drive the moving plate 221 to move closer to the positioning block 225. This process utilizes the cooperation of the slide rail 227 and the slider 228 to make the moving plate 221 move back and forth smoothly, ensuring that the upper cover 10 and the lower cover 11 are stably attached together. (See reference) Figure 7 and Figure 8As shown in the diagram, with the robotic arm 30 driving the suction cup 35 to adsorb the hinge 14 within the storage cavity 412a, the hinge 14 connects the upper cover 10 and the lower cover 11 into one unit. Therefore, the overall assembly station 22 features precise positioning, secure clamping, and flexible adjustment, effectively improving the assembly accuracy and firmness of the upper cover 10 and lower cover 11. This significantly reduces quality issues such as misalignment, poor fit, and loose assembly, substantially improving the quality of the finished box and the assembly pass rate. Furthermore, the modular structure facilitates debugging and maintenance, adapting to the needs of large-scale, high-precision automated production.
[0048] Preferably, the positioning block 225 in this embodiment has an L-shaped structure design, and a U-shaped groove 225a is provided on the positioning block 225. A threaded hole 220a is provided on the base 220. By using screws, bolts and other connecting parts to pass through the U-shaped groove 225a and connect to the threaded hole 220a, it can be ensured that the positioning block 225 can maintain absolute stability after adjusting its relative position with the base 220.
[0049] It should be noted that the transfer guide 43 and drive guide 50 in this embodiment have the same structure and working principle as those in the prior art, and will not be described in detail here. In addition, this embodiment also includes a dispensing machine 26 on the machine base 2, see reference... Figure 1 The structure shown is identical to existing technologies in terms of overall structure and working principle. When a label, magnet, or hinge adsorbed by the suction cup is placed at the dispensing port of the dispensing machine, the sensor on the dispensing machine can detect the position of the component and send a signal to the dispensing machine to dispense glue. During the entire box assembly operation, the label 13 adsorbed by the suction cup 35 needs to be dispensed by the dispensing machine 26 and then adhered to the outer wall of the top cover 10, i.e., the label 13 is pasted on... Figure 7 and Figure 8 The grooves on the outer walls of the upper cover 10 and the lower cover 11 are shown; similarly, the assembly of the magnet 12 and the hinge 14 in this embodiment are also performed by dispensing glue through the glue dispensing machine 26.
[0050] The overall assembly working principle of the automatic assembly equipment for box bodies according to this utility model is as follows: In this solution, the feeding mechanism 4 is provided with two sets. One set is for automatic feeding of multiple labels 13, and the other set is for automatic feeding of multiple hinges 14. After the robotic arm 30 places the upper cover 10 into the positioning block 201 via the suction cup 35, the suction cup 35 can grab the labels 13 in the storage cavity 412a. After being glued by the dispensing machine 26, the labels 13 are adhered to the outer wall of the upper cover 10. As the suction cup 35 again picks up the upper cover 10 with the labels 13, it is placed vertically in the contour seat 211. After the limiting block 213 presses against the upper cover 10, the robotic arm 30 can drive the suction cup 35 to move to the other side of the upper cover 10, that is, the inner side of the upper cover 10, so that the suction cup 35 can pick up and grasp the inner wall of the upper cover 10, ensuring that the upper cover 10 can be held in place. Figure 3 The shown posture is then placed back into the positioning block 201 to facilitate the subsequent assembly of the magnets 12 on the inner wall of the upper cover 10; similarly, after several magnets 12 are sequentially pushed to... Figure 9 When the magnet 12 is positioned to the right of the stepped groove 23, the robotic arm 30 drives the suction cup 35 to attract the magnet 12. Preferably, in this embodiment, two sets of robotic arms 30 and suction cups 35 are provided. After the magnet 12 is glued to the side away from the suction cup 35, it can be aligned with the mounting groove 100 on the inner wall of the upper cover 10. At this time, the auxiliary cylinder 25 drives the auxiliary block 250 to abut against the outer wall of the upper cover 10, ensuring that the suction cup 35 extends the magnet 12 into the mounting groove 100 and sticks it to its inner wall. For the assembly of the magnet 12 in the lower cover 11, the labeling 13 and the adjustment of the placement posture of the lower cover 11 are the same as those of the upper cover 10, and will not be described in detail here. Since the suction cup 35 needs to place the magnet 12 after attracting it, Figure 6 The clamping arm 215 shown provides vertical clamping, allowing the suction cup 35 to attract the magnet 12 from the other side. This is in contrast to the magnet 12 inside the upper cover 10, ensuring that the two magnets 12 attract each other when close. As the upper cover 10 and lower cover 11 are placed on the moving plate 221 and the fixed base 222 of the base 220 respectively, the material transfer cylinder 226 drives the lateral displacement of the material transfer stage 40, causing the upper cover 10 and lower cover 11 to be stably and tightly pressed together. Similarly, as the suction cup 35 attracts the hinge 14 inside the storage cavity 412a, the shape of which can be referenced... Figure 7 and Figure 8 As shown in the diagram, after the dispensing operation by the dispensing machine 26, the hinges 14 are respectively attached to the upper cover 10 and the lower cover 11. The upper cover 10 and the lower cover 11 rely on these hinges 14 to open and close. Finally, the assembled box is transferred to the machine station 2 for storage via the suction cup 35. Therefore, this overall structure has a reasonable layout. Through the coordinated operation of each station, it significantly improves the automation level and production efficiency of box assembly, reduces labor costs, and ensures consistent assembly quality.
