Description

Technical Field

[0001] This invention relates to the field of bottle cap production equipment technology, and in particular to a fully automatic alignment and assembly machine. Background Technology

[0002] In order to improve the aesthetics or information carrying capacity of bottle caps, especially wine bottle caps, a decorative ring is often set on the outside of the bottle cap during production.

[0003] Decorative rings can be used to create exquisite patterns to enhance the overall aesthetics of bottle caps. They can also be used to set QR codes or related product information, ensuring the cap's information-bearing capacity while minimizing damage. Decorative rings are typically snapped onto the outside of the lower sleeve, and the connection between the two is achieved by engaging the positioning teeth of the inner ring of the decorative ring with the mounting groove of the lower sleeve.

[0004] The existing clamping method is done manually, which makes it difficult to ensure the coaxiality of the lower sleeve and the decorative ring during assembly. As a result, the decorative ring often fails to clamp onto the lower sleeve, requiring repeated adjustments to achieve the desired fit, resulting in low assembly efficiency. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fully automatic alignment and assembly machine. By replacing manual assembly with mechanical methods, the assembly efficiency of the decorative ring and the lower sleeve is high, and the coaxiality of the decorative ring and the lower sleeve can be effectively guaranteed during assembly, thus ensuring assembly accuracy. At the same time, based on the self-clamping structure of the decorative ring and the lower sleeve, the lower sleeve is rotated to align. When the alignment is good, the lower sleeve undergoes axial displacement under the action of the spring, thereby automatically completing the assembly of the decorative ring and the lower sleeve.

[0006] A fully automatic alignment and assembly machine includes a worktable and a turntable rotatably mounted on the worktable. The worktable is provided with a lower sleeve loading station, a decorative ring loading station, and a decorative ring pressing station. The turntable is provided with multiple support fixtures along its circumference. The support fixtures are used to provide support for the lower sleeve and drive the lower sleeve to rotate when the lower sleeve fixture moves with the turntable to the decorative ring pressing position, so that the lower sleeve automatically finds and aligns with the decorative ring during the rotation process. The lower sleeve loading station is used to load the lower sleeve onto the support fixture. The decorative ring loading station is used to load the decorative ring. The decorative ring pressing station is used to drive the decorative ring and the lower sleeve to be coaxial and to drive the decorative ring to press down on the lower sleeve. During the process of the support fixture driving the lower sleeve to rotate, it cooperates with the lower sleeve to complete the alignment and positioning. After the lower sleeve and the decorative ring are aligned and positioned, the support fixture stops rotating.

[0007] Furthermore, the supporting fixture includes an annular pad, a supporting cylinder, a rotating shaft, and a supporting sleeve for fixing the lower sleeve. The annular pad is fixedly mounted on the turntable. The supporting cylinder is coaxially mounted on the annular pad. The rotating shaft is coaxially rotatably mounted inside the supporting cylinder. The upper end of the rotating shaft extends to the outside of the supporting cylinder, and the lower end of the rotating shaft extends below the turntable. The supporting sleeve has an inverted T-shaped structure. The supporting sleeve is coaxially mounted on the upper end of the rotating shaft and can move linearly along the axial direction of the rotating shaft. A spring is provided between the supporting sleeve and the supporting cylinder.

[0008] Furthermore, a motor with its output shaft vertically upward is provided at the pressing position of the decorative ring. The motor is connected to a drive cylinder, and the drive cylinder drives the motor to move linearly in the vertical direction. When the motor moves vertically to its position, the output shaft of the motor is connected to the rotating shaft through a friction plate.

[0009] Furthermore, the lower sleeve loading station is equipped with a lower sleeve feeding machine and a lower sleeve unloading mechanism located at the discharge end of the lower sleeve feeding machine. The lower sleeve unloading mechanism is used to send the lower sleeve from the discharge end of the lower sleeve feeding machine to the support fixture on the turntable.

[0010] Furthermore, the decorative ring feeding station is equipped with a decorative ring feeding machine and a decorative ring unloading mechanism located at the discharge end of the decorative ring feeding machine. The decorative ring unloading mechanism is used to clamp the decorative rings at the discharge end of the decorative ring feeding machine to the lower sleeve located at the decorative ring pressing station.

[0011] Furthermore, the decorative ring feeding mechanism includes a pressing cylinder, a rotating cylinder, a connecting plate, and two clamps. The output end of the pressing cylinder is connected to the cylinder body of the rotating cylinder. The connecting plate is disposed at the output end of the rotating cylinder. The two clamps are used to clamp the outer edge of the decorative ring, and the two clamps are centrally symmetrically disposed on the connecting plate.

[0012] Furthermore, it also includes a lower sleeve pressing detection station, which is equipped with a lower sleeve height detection mechanism for detecting the lower sleeve height.

[0013] Furthermore, it also includes a decorative ring inspection station, a genuine product unloading station, and a scrap product unloading station arranged sequentially after the decorative ring pressing station. The decorative ring inspection station is equipped with a decorative ring height detection mechanism for detecting whether the decorative ring has been pressed into place. The genuine product unloading station and the scrap product unloading station are each equipped with a unloading robot.

[0014] The objective of this invention is achieved through the following technical solution: The beneficial effects of this invention are: This invention uses mechanical assembly instead of manual assembly, resulting in high efficiency in assembling the decorative ring and the lower sleeve. During assembly, the coaxiality of the decorative ring and the lower sleeve is effectively guaranteed, ensuring assembly accuracy. Simultaneously, based on the self-clamping structure of the decorative ring and the lower sleeve, the lower sleeve is rotated for alignment. When the alignment is good, the lower sleeve undergoes axial displacement under the action of a spring, thereby automatically completing the assembly of the decorative ring and the lower sleeve.

[0016] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] See Figures 1-6 The present invention provides a technical solution: Example: like Figures 1-6 As shown, a fully automatic alignment and assembly machine includes a worktable 1 and a turntable 2 rotatably mounted on the worktable 1. The worktable 1 is provided with a lower sleeve loading station, a decorative ring loading station, and a decorative ring pressing station. The turntable 2 is provided with a plurality of support fixtures 3 along its circumference. The support fixtures 3 are used to provide support for the lower sleeve and drive the lower sleeve to rotate when the lower sleeve fixture moves with the turntable 2 to the decorative ring pressing position, so that the lower sleeve automatically finds and aligns with the decorative ring during the rotation process. The lower sleeve loading station is used to load the lower sleeve onto the support fixture 3. The decorative ring loading station is used to load the decorative ring. The decorative ring pressing station is used to drive the decorative ring and the lower sleeve to be coaxial and to drive the decorative ring to press down on the lower sleeve. During the process of the support fixture 3 driving the lower sleeve to rotate, it cooperates with the lower sleeve to complete the alignment and positioning. After the lower sleeve and the decorative ring are aligned and positioned, the support fixture 3 stops rotating.

[0018] The turntable 2 is driven to rotate by a stepper motor 9.

[0019] like Figure 2 and Figure 3 As shown, the support fixture 3 includes an annular pad 4, a support cylinder 5, a rotating shaft 6, and a support sleeve 7 for fixing the lower sleeve. The annular pad 4 is fixedly mounted on the turntable 2. The support cylinder 5 is coaxially mounted on the annular pad 4. The rotating shaft 6 is coaxially rotatably mounted inside the support cylinder 5. The upper end of the rotating shaft 6 extends to the outside of the support cylinder 5, and the lower end of the rotating shaft 6 extends below the turntable 2. The support sleeve 7 has an inverted T-shaped structure. The support sleeve 7 is coaxially mounted on the upper end of the rotating shaft 6 and can move linearly along the axial direction of the rotating shaft 6. A spring 8 is provided between the support sleeve 7 and the support cylinder 5.

[0020] The decorative ring pressing station is equipped with a motor 9 with its output shaft vertically upward. The motor 9 is connected to a drive cylinder 10. The drive cylinder 10 drives the motor 9 to move linearly in the vertical direction. When the motor 9 moves vertically to its position, the output shaft of the motor 9 is connected to the rotating shaft 6 through a friction plate.

[0021] The lower sleeve loading station is equipped with a lower sleeve feeding machine 11 and a lower sleeve unloading mechanism 12 located at the discharge end of the lower sleeve feeding machine 11. The lower sleeve unloading mechanism 12 is used to feed the lower sleeve from the discharge end of the lower sleeve feeding machine 11 to the support fixture 3 on the turntable 2. The lower sleeve unloading mechanism 12 is a combination of a cylinder and a push rod, which is a common technical means in this field. The specific structure and principle are not described in detail here.

[0022] The decorative ring feeding station is equipped with a decorative ring feeding machine 13 and a decorative ring unloading mechanism 14 located at the discharge end of the decorative ring feeding machine 13. The decorative ring unloading mechanism 14 is used to clamp the decorative ring at the discharge end of the decorative ring feeding machine 13 to the lower sleeve located at the decorative ring pressing station.

[0023] The decorative ring feeding mechanism 14 includes a pressing cylinder 15, a rotating cylinder 16, a connecting plate 17, and two clamps 18. The output end of the pressing cylinder 15 is connected to the cylinder body of the rotating cylinder 16. The connecting plate 17 is disposed at the output end of the rotating cylinder 16. The two clamps 18 are used to clamp the outer edge of the decorative ring, and the two clamps 18 are centrally symmetrically arranged on the connecting plate 17. The two clamps 18 correspond to the discharge end of the decorative ring feeding machine 13 and the pressing station of the decorative ring, respectively. The clamps 18 are existing technology, and their specific principles and structures will not be described in detail here.

[0024] It also includes a lower sleeve pressing detection station, which is equipped with a lower sleeve height detection mechanism 19 for detecting the lower sleeve height.

[0025] It also includes a decorative ring inspection station, a good product unloading station, and a scrap unloading station located sequentially after the decorative ring pressing station. The decorative ring inspection station is equipped with a decorative ring height detection mechanism for detecting whether the decorative ring has been pressed into place. The good product unloading station and the scrap unloading station are each equipped with a unloading robot.

[0026] The lower sleeve height detection mechanism 19 and the decorative ring height detection mechanism both use a cylinder to drive a photoelectric downward pressure detection device. The specific principles and structures are conventional techniques in this field and will not be elaborated here.

[0027] in, Figure 1 In the diagram, 'a' represents the lower sleeve loading station; 'b' represents the lower sleeve pressing and inspection station; 'c' represents the decorative ring loading station; 'd' represents the decorative ring pressing station; 'e' represents the decorative ring inspection station; 'f' represents the good product unloading station; and 'g' represents the scrap product unloading station.

[0028] Working principle: (1) The lower sleeve is fed to the support fixture 3 by the lower sleeve feeding machine 11 and the lower sleeve feeding mechanism 12, and the support fixture 3 supports the lower sleeve.

[0029] (2) After the lower sleeve is in place, the support fixture 3 rotates synchronously with the turntable 2. When the support fixture 3 rotates to the lower sleeve pressing detection station, the lower sleeve height detection mechanism 19 detects whether the lower sleeve is in place. If the lower sleeve is detected to be in place, the decorative ring feeding station feeds the material normally. If the lower sleeve is detected to be not in place, the decorative ring feeding station does not feed the material.

[0030] (3) When the turntable 2 continues to rotate to the decorative ring pressing station, the turntable 2 stops for time t1 (t1 is 15 seconds in this embodiment). During this process, the decorative ring loading station synchronously drives the decorative ring to be coaxial with the lower sleeve, and makes the decorative ring press down on the lower sleeve. Specifically: 1) One of the two clamps 18 is used for loading the decorative ring, and the other is used to clamp the decorative ring at the same time as loading the decorative ring, in preparation for the next loading. 2) After clamping the decorative ring, the clamp 18 rotates 180 degrees through the rotary cylinder 16 to align the decorative ring with the lower sleeve (coaxial); 3) Then, under the action of the pressing cylinder 15, the decorative ring is driven down and presses down on the lower sleeve (when the decorative ring and the lower sleeve are not aligned, the lower sleeve is driven down by the decorative ring under the action of the limiting teeth on the outer ring of the lower sleeve and the limiting teeth on the inner ring of the decorative ring). During the downward movement of the lower sleeve, the support sleeve 7 moves down synchronously and compresses the spring 8. During this process, the clamp 18 always clamps the decorative ring. When time t1 ends, the clamp 18 releases the decorative ring.

[0031] (4) The drive cylinder 10 drives the motor 9 to move upward. When the motor 9 reaches its upper position, its output shaft is fixed to the rotating shaft 6. When the output shaft of the motor 9 rotates, it drives the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 drives the support sleeve 7 on it to rotate. When the support sleeve 7 rotates, the lower sleeve on it rotates synchronously. In this embodiment, t1 is taken as one rotation cycle of the motor 9. The number of rotations of the motor 9 in one rotation cycle is a positive integer. In this embodiment, it is two rotations. That is, the lower sleeve rotates a maximum of two rotations in one rotation cycle. At the same time, the rotational force of the motor 9 is set to stop when the decorative ring and the lower sleeve are aligned and locked.

[0032] During the rotation of the lower sleeve, the decorative ring is clamped by the clamp 18, causing relative rotation between the lower sleeve and the decorative ring. This relative rotation allows for automatic alignment and positioning. Once aligned, the limiting teeth of the inner ring of the decorative ring completely intersect with the limiting teeth of the lower sleeve. At this point, the lower sleeve rebounds and moves upwards under the action of the support sleeve 7 and the spring 8, thus automatically completing the engagement between the lower sleeve and the decorative ring.

[0033] As mentioned above, within time t1, if the decorative ring and the lower sleeve are aligned and engaged, the resistance between them increases to a level greater than the rotational force of motor 9, causing motor 9 to automatically stop. At this point, the decorative ring and the lower sleeve are considered qualified products (i.e., genuine products). However, if the decorative ring and the lower sleeve are not aligned and engaged by the end of time t1, motor 9 completes one rotation cycle and automatically stops. In this case, the decorative ring and the lower sleeve are considered unqualified products and will be rejected by subsequent processes.

[0034] (5) Decorative Ring Inspection: Turntable 2 continues to rotate to the decorative ring inspection station, and the height of the decorative ring is detected by the decorative ring height detection mechanism. If the decorative ring and the lower sleeve are aligned and engaged, the height of the decorative ring is lower than when it was loaded, and it is a qualified product; otherwise, it is higher and is a defective product. When the decorative ring height detection mechanism detects a qualified product, the product is unloaded at the good product unloading station; if it is a defective product, the product is unloaded at the scrap unloading station. Among them, the unloading robot is controlled by the controller, the decorative ring height detection mechanism is electrically connected to the controller, the unloading robot is electrically connected to the controller, the lower sleeve height detection mechanism 19 is electrically connected to the controller, and the clamp 18 is electrically connected to the controller. (This control process is a conventional technical means in this field, and the specific principle is not described here.) like Figures 4-6 As shown, this device is also applicable to the alignment and assembly of a decorative ring and a lower sleeve with a structure in which "a slot is provided on the outer circumference of the lower sleeve 20 and a locking block that matches the slot is provided on the inner circumference of the decorative ring 21".

[0035] This invention uses mechanical assembly instead of manual assembly, resulting in high efficiency in assembling the decorative ring and the lower sleeve. During assembly, the coaxiality of the decorative ring and the lower sleeve is effectively guaranteed, ensuring assembly accuracy. Simultaneously, based on the self-clamping structure of the decorative ring and the lower sleeve, the lower sleeve is rotated for alignment. When the alignment is good, the lower sleeve undergoes axial displacement under the action of a spring, thereby automatically completing the assembly of the decorative ring and the lower sleeve.

[0036] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
