Description

Technical Field

[0001] The present invention belongs to the technical field of automated installation equipment, and in particular relates to an assembly and loading device for a spliced ​​packaging box and an installation machine. Background Art

[0002] Hinges are essential components of modular packaging boxes. Assembly requires first aligning the box body and lid. Then, the two metal pieces of the unfolded hinge are fixed to the box body and lid at the joint. Traditionally, hinges are installed manually, resulting in low efficiency and precision.

[0003] Prior art also employs mechanical devices to install hinges. For example, document CN204747953 discloses an automatic hinge installation machine for use in a door frame production line. The machine includes a screw-driving mechanism comprising an electric screwdriver secured to a mounting bracket. The electric screwdriver has a screw inlet at its head and a screw reservoir below the screw inlet. The mounting bracket is slidably connected to a second guide rail via a lifting guide slider.

[0004] The problems with the above technical solution include at least the following: the hinge needs to be manually inserted into the fixed installation part at the lower end of the electric screwdriver head. Since the manual insertion trajectory overlaps with the lifting trajectory of the electric screwdriver, it is more likely that the electric screwdriver head will scratch the hand or arm. Safety issues.

[0005] For example, the document with application number 2025105040855 discloses a nut machine for producing laptop computer casings, which includes a nut machine body and a clamping assembly; the clamping rough shear includes a chassis and a box cover; the operating table is provided with an installation slot, and the installation slot is fixedly connected to two linear guide rails, and a stepper motor is provided to connect the linear guide rails.

[0006] This solution uses a stepper motor to drive a linear guide rail, which in turn drives the chassis. This allows a single nut runner to accommodate multiple laptop cases. Using a flat conveyor system prevents the manual operator's movement from overlapping the nut cutter head on the nut runner, but the device significantly increases its footprint.

[0007] For the packaging box that is the application object of the present application, a technical solution is needed that occupies little space and has high safety when manually inserting hinges, and can even replace the manual insertion of hinges. Summary of the Invention

[0008] In response to the above-mentioned problems, the purpose of the present invention is to provide an assembly and loading device for a spliced ​​packaging box. By improving the loading structure and changing the loading method, the manual operation trajectory can completely avoid the movement trajectory of the screwdriver head, and the difficulty of manual insertion can be reduced, thereby improving construction safety and work efficiency.

[0009] The specific technical solutions of the present invention are as follows: The cam is adapted to move the packaging box towards the outside of the packaging box so that the packaging box can be moved along the longitudinal axis of the packaging box so as to move the packaging box towards the outside of the packaging box. A screw channel communicating with the sample loading groove is further provided on the side wall of the fixing block away from the sample loading groove.

[0010] As a further preferred embodiment of the present invention, upper limit balls and lower limit balls are relatively provided on the upper side wall and lower side wall of the preparatory groove close to the groove opening.

[0011] As a further preferred embodiment of the present invention, the sample loading structure further includes a sample introduction unit, which includes a fixed frame, a cylinder arranged on the fixed frame, and a sample introduction rack arranged on the output end of the cylinder and used to probe into the preparatory groove.

[0012] As a further preferred embodiment of the present invention, the movement direction of the sample loading rack in the preparatory groove is perpendicular to the extension direction of the sample loading channel.

[0013] As a further preferred embodiment of the present invention, the sample loading structure has at least one hinge for loading samples, and the fully unfolded hinge moves in the sample loading channel, and when the hinge is completely located in the sample loading groove, the sample loading channel matches the opening on the hinge.

[0014] As a further preferred embodiment of the present invention, at least one of the sample injection racks is provided with a hanging rod plugged into the opening on the hinge.

[0015] As a further preferred embodiment of the present invention, the hinge is made of a magnetic metal material; an installation groove is provided on the inner groove wall of the loading groove away from the opening, and a magnet is provided in the installation groove.

[0016] As a further preferred embodiment of the present invention, the pressing structure includes a platform for supporting the packaging box, at least two pressing frames arranged on the platform and located on two opposite sides or two corners of the packaging box, and a presser slidably connected or rotatably connected to the pressing frames and abutting against the surface of the packaging box facing away from the platform.

[0017] As a further preference of the present invention, the power structure includes a base, two oppositely arranged rotating plates arranged on the two side edges of the platform different from those on which the loading structure is installed, two fixed plates arranged on the base and parallel to the two rotating plates respectively, a rotating shaft rotatably connected to the fixed plate and fixedly connected to the rotating plate, and a motor for driving the rotating shaft to rotate.

[0018] The present invention also provides an installation machine, which includes any one of the above-mentioned spliced ​​packaging box assembly and sample loading devices.

[0019] The beneficial effects of the present invention are: The assembly and loading device provided by the present invention can pre-assemble hinges or connectors at the connection of the packaging box. The manner of assembling the hinges or connectors has no particular order with the order of installing the packaging box, thereby reducing the process and time requirements for loading. Even if the hinges or connectors are manually inserted, the manual motion trajectory will not intersect with the trajectory of other motion structures such as a nut machine or a press, thereby ensuring the safety of loading.

[0020] The assembly sample loading device provided by the present invention can further replace the manual sample loading method, thereby greatly improving work efficiency.

[0021] The mounting machine provided by the present invention can achieve the effect of not intersecting the sample loading trajectory and the trajectory of other motion structures while occupying a small space, and has the advantages of strong practicality and good economy.

DETAILED DESCRIPTION

[0028] In the description of the present invention, it should be understood that the terms "upper", "lower", "inside", "outside", "left", "right", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the inventive product is conventionally placed when in use, or are the orientations or positional relationships conventionally understood by those skilled in the art. These are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, terms such as "disposed" and "connected" should be understood broadly. For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection via an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0030] First, it should be noted that the mounting machine described herein generally comprises a workbench to which the packaging box is mounted and a nut runner located at the upper end of the workbench. The workbench is equipped with the following: a pressing mechanism 1, a power mechanism 2, and a sample loading mechanism 3. The nut runner is a device that moves along a work surface parallel to the upper end of the workbench and drives screws into the packaging box. The nut runner can employ conventional devices, so a detailed description thereof will not be provided.

[0031] A packaging box refers to a spliced ​​structure with a box body and a lid. The box body and the lid are rectangular in shape. The upper end of the box body is open and generally has a continuous inner recessed groove around the opening. The cross-section of the box lid is an inverted U-shape, and its lower end is placed in the inner recessed groove to ensure that the outer surface of the box lid is flush with the outer surface of the box body. The hinge is generally installed on one side, and there are at least one hinge. The two leaves of the hinge are connected to the lid and the box body respectively to form a hinge point. Furthermore, the box lid and the box body can be pre-machined with grooves for embedding the hinge so that the hinge does not protrude from the surface of the packaging box. The box lid and the box body can also be machined with pre-made holes for screws to reduce the risk of cracking.

[0032] Reference Attachment Figure 1 ~Attached Figure 4 As shown, the assembly and loading device includes a pressing structure 1 for limiting and fixing the spliced ​​packaging boxes a, a power structure 2 for driving the pressing structure 1 to rotate, and also includes a loading structure 3.

[0033] In this embodiment, the pressing structure 1 specifically includes: a platform 11 for supporting the packaging box a, at least two pressing frames 12 arranged on the platform 11 and located on two opposite sides or two corners of the packaging box a, and a presser 13 slidably connected or rotatably connected to the pressing frame 12 and used to abut the surface of the packaging box a facing away from the platform 11.

[0034] Among them, the number of the pressing frames 12 can be two, three or four. In the case of two, the press 13 is preferably connected to the pressing frame 12 in a sliding manner. In this case, the press 13 can be a lifting motor or cylinder fixed on the pressing frame 12, and a pressure plate abutting the upper surface of the packaging box a. In this case, the two pressing frames 12 should be arranged on the outside of the two side edges of the packaging box a; in the case of four, the pressing frames 12 are respectively arranged on the outside of the four corners of the packaging box a. In this case, the press 13 is mainly composed of a rotating motor fixed on the pressing frame 12, a lifting motor connected to the rotating motor, and a pressure plate and other common components; in the case of three, the press 13 can choose to use both rotating and sliding connections in parallel. The above connection methods and the specific structure of the press 13 are conventional choices that can be made by those skilled in the art according to actual needs, so they will not be described in detail here.

[0035] In this embodiment, the power structure 2 specifically includes: a base 21, two oppositely arranged rotating plates 22 arranged on the two side edges of the platform 11 different from the side edges where the loading structure 3 is installed, two fixed plates 23 arranged on the base 21 and parallel to the two rotating plates 22, a rotating shaft 24 rotatably connected to the fixed plate 23 and fixedly connected to the rotating plate 22, and a motor 25 for driving the rotating shaft 24 to rotate.

[0036] The base 21 is located at the lower end of the platform 11 and is parallel to it. The distance between the base 21 and the platform 11 is sufficient to prevent collision and friction between the platform 11 and the base 21 during rotation. The rotating plate 22 is fixedly connected to the platform 11 or integrally formed with it. The rotating plate 22 can drive the platform 11 to rotate about the rotating axis 24 as the centerline. The motor 25 can be a commonly used structure such as a stepper motor or servo motor.

[0037] It is worth noting that the motor 25 of this embodiment can drive the rotating shaft 24 to rotate, thereby causing the platform 11 to have a unilateral cyclic motion: 90 degrees counterclockwise (angle parallel to the base 21) - return to the original position (angle parallel to the base 21). Furthermore, it can have a bilateral cyclic motion: a basic cyclic motion of 90 degrees counterclockwise (angle parallel to the base 21) - return to the original position (angle parallel to the base 21) - 90 degrees clockwise (angle parallel to the base 21) - return to the original position (angle parallel to the base 21). The unilateral cyclic motion corresponds to the unilateral placement of the sample loading structure 3, while the bilateral cyclic motion corresponds to the bilateral placement of the sample loading structure 3.

[0038] In this embodiment, the sample loading structure 3 includes a fixed sample unit 31 installed on the pressing structure 1, and the fixed sample unit 31 includes a fixed block 311 that is fitted and connected to the outer wall of the packaging box a, a sample loading groove 312 arranged at the upper end of the fixed block 311 and located at the connection of the packaging box a, and a preparatory groove 313 arranged on the fixed block 311 and located at the lower end of the sample loading groove 312; the notch of the sample loading groove 312 faces the outer wall of the packaging box a; an opening 314 that is respectively connected to the lower end of the sample loading groove 312 and the upper end of the preparatory groove 313 is provided in the fixed block 311, and the preparatory groove 313, the opening 314, and the sample loading groove 312 are connected to form a sample loading channel distributed along the height direction of the fixed block 311; a screw channel 315 that is connected to the sample loading groove 312 is also provided on the side wall of the fixed block 311 away from the sample loading groove 312. There is at least one sample loading structure 3 for loading samples on the hinge c, and the fully unfolded hinge c moves in the sample loading channel. When the hinge c is completely located in the sample loading groove 312, the sample loading channel matches the opening on the hinge c.

[0039] Among them, based on the restored state (the angle at which the platform 11 is parallel to the base 21), the sample loading channel, from top to bottom, is composed of a sample loading slot 312, an opening 314, and a preparatory slot 313. The sample loading slot 312 is located on the inner side wall of the notch of the fixed block 311 and corresponds in vertical height to the connection point of the packaging box a. The notch of the sample loading slot 312 faces the outer side wall of the packaging box a. This allows, when the hinge c is located in the sample loading slot 312, the motor 25 drives the platform 11 to rotate clockwise or counterclockwise to an angle perpendicular to the base 21. At this time, under the action of gravity, the hinge c fits into the connection point with the packaging box a. The screw is installed on the nut machine and screwed in through the screw channel 315, completing the connection between the hinge c and the packaging box a. After the connection is completed, the motor 25 drives the platform 11 to restore.

[0040] It is worth mentioning that if the opening 314 and the preparatory groove 313 are not provided, the hinge c must be installed in the loading groove 312 before the packaging box a is fixed on the platform 11. After the motor 25 is programmed, the time for it to be placed in the packaging box a is limited. The completion of loading the hinge c and placing the packaging box a within the limited time requires high manual operation. Moreover, the trajectory of the manual insertion of the hinge c intersects with the position of the press 13 and the nut machine, which is prone to scratches and other safety issues. Therefore, the inventor innovatively shifted the position of the loading hinge c from the inner side of the fixed block 311 to the other side, that is, the notch of the preparatory groove 313 can be set on the opposite side, in which case the notch of the preparatory groove 313 is away from the loading groove 312, or it can be set on the other two oppositely arranged sides, in which case the notch of the preparatory groove 313 is also on a different side from the loading groove 312. Regardless of which side the hinge is inserted into the loading slot 312, it must be ensured that the position of hinge c within the loading slot 312 is aligned with the opening 314. This ensures that, regardless of whether the hinge is rotated 90 degrees counterclockwise or clockwise, the hinge c can be swung from the pre-slot 313 through the opening 314 into the loading slot 312, thereby ensuring that the hinge c reaches the preset position before the connection between the package box a and the nut machine is aligned. Furthermore, to ensure the success rate of hinge c being swung into the loading slot 312, it is only necessary to ensure that the motor 25 drives the platform 11 to rotate at a certain speed, that the hinge c is unobstructed when moving within the loading channel or that the friction between the hinge c and the loading channel is low, and that the hinge c has sufficient deadweight. Some of these conditions are objectively met, while some conditions can also be optimized through limited testing, thus having good practicality.

[0041] It is worth noting that when there are two sample loading structures 3, one is used to load the sample hinge c, and the other is generally used to load a locking member such as a latch and a pinhole. In this case, the shapes of the sample loading groove 311, opening 314, and preparatory groove 313 on the sample loading structure 3 need to be modified accordingly. In addition, a sample loading structure 3 can be provided with multiple sample loading channel structures to complete the assembly and connection of multiple hinges c on the same side, thereby improving the connection strength of the packaging box a.

[0042] In some preferred embodiments, upper and lower limiting balls 316 and 317 are disposed on the upper and lower sidewalls of the preparatory groove 313, respectively, near the groove opening. This arrangement prevents the hinge C (for example) from accidentally falling out of the preparatory groove 313 after entering the preparatory groove 313. It also serves to limit the hinge C to a position corresponding to the opening 314, thereby increasing the chances of it being successfully inserted into the loading groove 311.

[0043] In some preferred embodiments, in addition to manually loading the hinge c into the preparatory groove 313, an automatic loading method can also be used: the loading structure 3 also includes a sample loading unit 32, which includes a fixed frame 321, a cylinder 322 disposed on the fixed frame 321, and a sample loading rack 323 disposed at the output end of the cylinder 322 and configured to probe into the preparatory groove 313. The movement direction of the sample loading rack 323 within the preparatory groove 313 is perpendicular to the extension direction of the sample loading channel.

[0044] Among them, the fixed frame 321 is arranged perpendicularly to the base 21, the movement stroke of the cylinder 322 is parallel to the platform 11 in the restored state, and the sample loading rack 323 is used to support the hinge c or other connecting parts (pin and hole structure). At the sample loading rack 323 for loading the hinge c, a hanging rod 324 is provided on the sample loading rack 323 for plugging into the opening on the hinge c.

[0045] As some preferred embodiments, the hinge c is made of a metallic material containing magnetism; a mounting groove is provided on the inner groove wall of the loading groove 312 away from the opening 314, and a magnet 318 is provided in the mounting groove. The magnet 318 is provided mainly for magnetically adsorbing the hinge c thrown into the loading groove 311, so that the position of the hinge c in the loading groove 312 is accurate, which is convenient for screwing in the screw. It is understandable that even if there is a problem of a slight offset in the position of the hinge c or the connector in the loading groove 312 in the absence of magnetic adsorption, since the screw has the function of correcting the position when it is screwed in, the hinge c or the connector will not fail to install.

[0046] It is understandable that the motors, cylinders and other structures mentioned in the above content are all started by power supply, and closed-loop control of position, speed or torque can also be achieved by additionally configuring control systems such as PLC, encoders, drives and other known structures and technologies.

[0047] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
