Description

Technical Field

[0001] The utility model relates to the technical field of trolley case assembly equipment, in particular to automatic trolley case assembly equipment. Background Art

[0002] A trolley case refers to a suitcase with a trolley and wheels, which is widely used because of its convenience. At the same time, the trolley case is also divided into a single-tube trolley and a double-tube trolley because the case has a trolley. The tube of the trolley is also divided into a square tube and a round tube, which is convenient for dragging when walking and greatly reduces the burden. In the manufacturing process of the trolley case, it is necessary to assemble the wheels at the bottom of the trolley case, assemble the trolley inside the trolley case, and assemble the trolley handle. When assembling the trolley handle, a semi-automatic screwing device is needed to install screws inside it. After each trolley handle is screwed, it is necessary to manually place the trolley handle to be assembled under the screwing device, resulting in a slow screwing efficiency. At the same time, the screwing device is also easy to injure the operator's hand, causing a safety accident. Secondly, in the process of screwing the trolley handle, the current screwing device has an unstable fixation of the trolley handle, which ultimately makes the screwing position inaccurate, resulting in a large loss of the trolley handle. Therefore, an automatic assembly device for a trolley case is proposed to address the above problems.

[0003] In the published Chinese patent application, the publication number is: CN217513313U, and the patent name is: A trolley case automatic assembly device, including a base and a screw driving device, a screw driving device is arranged at the upper central position of the base, a slider is slidably connected at the central position of the top end of the base, the top end of the slider is fixedly connected with a positioning frame from front to back, a pull rod handle is arranged on the inner side of the positioning frame, a slide is fixedly connected to the left side of the top end of the base, a fixed block is fixedly connected to the top end of the slide, a first connecting rod is arranged on the outer side of the right end of the fixed block, the front end of the first connecting rod is rotatably connected to the second connecting rod through an axis, the bottom end of the second connecting rod is rotatably connected to a moving block through an axis, the moving block is slidably connected to the slide, the outer side of the right end of the moving block is rotatably connected to a ratchet through an axis, a stopper is arranged on the front end of the ratchet, and the stopper is fixedly connected to the moving block. The prior art provides a support plate, a sleeve, a pressure plate and a second spring, so that when the screw driving device installs the screws on the pull rod handle, the pull rod handle can be stably fixed, so that the position of the installation screws is more accurate, thereby reducing the loss rate of the pull rod handle. Although the prior art can solve the above technical problems, the prior art has certain limitations. In the prior art, the slider needs to be refilled into the equipment after the work is completed, and the process is relatively cumbersome. If the slider is long, it will cause inconvenience in manual handling. If it is short, the number of pull rod handles that can be placed is small, which increases the cumbersomeness of the work and affects the work efficiency.

[0004] In summary, in order to solve the problem of low assembly efficiency of the trolley handle of the trolley case existing in the prior art, the present invention is proposed to solve the problem. Utility Model Content

[0024] See also Figures 1 to 4 The utility model provides a technical solution: an automatic assembly device for a trolley case, which is used for assembling a trolley handle 5, including a base 1, a driving component, and a turntable 3. A fixing frame 7 is fixedly connected to the base 1, and the turntable 3 is mounted on the outer wall of the fixing frame 7 and the two are rotatably connected. The driving component is arranged on the base 1, and the driving component is transmission-connected to the turntable 3.

[0025] The driving component is used to drive the turntable 3 to rotate around the fixing frame 7.

[0026] A plurality of limit blocks 4 are arranged in a circular array above the turntable 3 and around the fixing frame 7. A limit slot is provided inside each limit block 4, and each limit slot is an assembly station. A material taking slot 6 is provided on the upper edge of the end of the limit block 4.

[0027] A support plate 8 is fixedly mounted on the fixing frame 7 , and a screw driving device is provided on the support plate 8 . The screw driving device is located above an assembly station.

[0028] Among them, when the driving component drives the turntable 3 to rotate around the fixed frame 7, it drives each limit block 4 to rotate and move, that is, each limit block 4 rotates and moves around the fixed frame 7. The fixed frame 7 and the support plate 8 are used to support and fix the screw driving device. The screw driving device adopts a flexible servo screw gun disclosed in the published Chinese patent application with publication number CN219747790U. The screw driving device is used to screw the pull rod handles on each limit block 4 in turn, and the pull rod handles are assembled after screwing. The driving component drives the turntable 3 to rotate, and the rotation of the turntable 3 drives each limit block 4 to be located under the screw driving device in turn. When the limit block 4 drives the pull rod handle to move to the bottom of the screw driving device, the screw driving device performs a screw driving operation on the pull rod handle.

[0029] Specifically, an automatic assembling device for a suitcase further includes a fixing plate 2 , which is fixedly mounted above the base 1 , and is cylindrical in shape as a whole, and is rotatably connected to a turntable 3 .

[0030] The fixing plate 2 is used to support the rotating disk 3. The outer circumferential edge of the rotating disk 3 is rotatably connected to the upper edge of the fixing plate 2.

[0031] Specifically, the driving component includes a servo motor 13, a disc 10, and a sheave 9. The sheave 9 is mounted on the outer wall of the fixed frame 7 and the two are rotatably connected. The sheave 9 is fixedly connected to the lower end of the rotating disc 3. The disc 10 is rotatably arranged on the base 1, and the output shaft end of the servo motor 13 is transmission-connected to the disc 10, and the disc 10 is transmission-connected to the sheave 9. The servo motor 13 is fixedly installed below the base 1. The output shaft end of the servo motor 13 is coaxially fixedly connected to the disc 10 after passing through the base 1. A plurality of slots 15 are provided along the outer circumference of the sheave 9. The outer circumference of the sheave 9 and the wall surface between two adjacent slots 15 are in the shape of an arc surface 14. The first protrusion 11 and the second protrusion 12 are fixedly connected to the disc 10, respectively. The second protrusion 12 is cylindrical, and the first protrusion 11 is cylindrical with a crescent-shaped cross section. The rotation of the disc 10 drives the first protrusion 11 and the second protrusion 12 to move. When the second protrusion 12 rotates and moves, it is sequentially inserted into each of the slots 15, and the second protrusion 12 pushes the groove wheel 9 to rotate.

[0032] The servo motor 13 drives the disc 10 to rotate after starting, and the disc 10 drives the first protrusion 11 and the second protrusion 12 to rotate and move. The second protrusion 12 is sequentially inserted into each slot 15 during the rotation and displacement process, and the second protrusion 12 drives the groove wheel 9 to rotate. The rotation of the groove wheel 9 drives the turntable 3 to rotate.

[0033] When in use, the pull rod handle 5 is placed inside the limit block 4, the size of the inside of the limit block 4 matches the size of the pull rod handle 5, and then the servo motor 13 is started to drive the disc 10 to rotate. During the rotation of the disc 10, the second protrusion 12 is inserted into the groove 15 on the groove wheel 9, thereby pushing the groove wheel 9 to rotate through the second protrusion 12. When the groove wheel 9 rotates, when the second protrusion 12 leaves the groove 15 provided on the groove wheel 9, the arc surface 14 of the groove wheel 9 contacts the disc 10, thereby limiting the rotation of the groove wheel 9, completing a circle as the disc 10 rotates, which is also a work station of the rotating disk 3, so that the next pull rod handle 5 is moved to the bottom of the screw driving device, and the screw driving device can screw the pull rod handle 5 during the intermittent rotation of the rotating disk 3. The above process continues. When all the pull rod handles 5 on the rotating disk 3 are processed, the servo motor 13 can be stopped, and the processed pull rod handle 5 can be taken out through the material trough 6 on the limit block 4.
