[0028] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Please see Figure 1 and Figure 2 An automatic furniture handle assembly machine includes a rotary table 100, a positioning component 200, a stamping station 300, and a material handling component 400. Several jigs 500 are spaced apart on the rotary table 100. The positioning component 200, the stamping station 300, and the material handling component 400 are arranged sequentially around the side of the rotary table 100 along the assembly direction of the product. The rotary table 100 is driven to rotate by a servo motor 110 to drive the jigs 500 to rotate. The positioning component 200 is used to position the jigs 500. The stamping station 300 is used to install a stamping machine, which performs stamping and riveting assembly on the products in the jigs 500. The material handling component 400 is used to unload the assembled products.

[0032] Specifically, in this embodiment, when assembling the two components of the furniture handle, the two components are placed sequentially into the fixture 500 by a person or a robot. A servo motor 110 and a reducer drive the rotating disk 100 to rotate, thereby rotating the fixture 500. Of course, other structures can also be used to drive the rotating disk 100; this is not limited here. When the fixture 500 rotates to the stamping station 300, the positioning component 200 positions one of the fixtures 500 on the rotating disk 100 to ensure the accurate positioning of the fixture 500 at the stamping station 300. Then, the stamping press at the stamping station 300 performs stamping and riveting on the two components within the fixture 500. The stamping machine is existing technology. It only needs to be set up at the stamping station 300. After the two parts of the furniture handle are stamped and assembled, the rotary table 100 will rotate again with the fixture 500 and rotate to the material picking component 400. The material picking component 400 will automatically pick up and collect the furniture handle that has been assembled in the fixture 500, thereby realizing the automatic assembly of the furniture handle. Automated assembly can effectively reduce production costs and realize large-scale and high-efficiency production. At the same time, it can also reduce labor costs and losses in the production process. In addition, the rotary table 100 automatically transports or outputs the fixture 500 to the stamping station 300, thereby avoiding manual operation and reducing safety hazards.

[0033] Additionally, please see Figure 3In order to facilitate the placement of the two parts to be assembled in the fixture 500, a loading slot 510 for placing the product is provided on the top of the fixture 500. The two parts are placed in the loading slot 510 to facilitate subsequent punching and riveting.

[0034] Please see Figure 3 and Figure 4 In this embodiment, in order to facilitate the positioning of the fixture 500, a positioning hole 520 is provided on the outer side wall of the fixture 500. Meanwhile, the positioning component 200 includes a positioning bracket 210, a positioning cylinder 220 and a positioning slider 230. The positioning cylinder 220 is mounted on the positioning bracket 210, and the positioning slider 230 is connected to the positioning cylinder 220. A positioning pin 240 corresponding to the positioning hole 520 is provided on the positioning slider 230. The positioning cylinder 220 can drive the positioning slider 230 to move, thereby inserting the positioning pin 240 into the positioning hole 520.

[0035] When the fixture 500, which is loaded with assembly parts, is rotated to the stamping station 300, the positioning cylinder 220 drives the positioning slider 230 to move toward the fixture 500. As the positioning slider 230 moves, it also moves the positioning pin 240 so that the positioning pin 240 is inserted into the positioning hole 520 of the corresponding fixture 500. By positioning the fixture 520, the fixture 500 at the stamping station 300 is accurately positioned, which facilitates the stamping machine at the stamping station 300 to stamp and rivet the two parts in the fixture 500, thereby ensuring the assembly quality of the furniture handle.

[0036] Please see Figure 5 and Figure 6 Since the stamping machine at the stamping station 300 will generate a certain stamping force when stamping and riveting the parts in the fixture 500, in order to ensure that the fixture 500 and the stamping machine cooperate, a support assembly 310 is also provided at the stamping station 300. The support assembly 310 is located at the bottom of the rotary table 100 and cooperates with the fixture 500. The support assembly 310 includes a support seat 311, a support block 312, a push cylinder 313 and a push block 314. The support block 312 is movably installed in the support seat 311. The push block 314 is connected to the push cylinder 313. The push cylinder 313 drives the push block 314 to move, thereby pushing the push block 314 into the bottom of the support block 312 to lift the push block 312 upward.

[0037] When the corresponding fixture 500 is rotated by the rotary table 100 to the stamping station 300, the push cylinder 313 in the support assembly 310 drives the push block 314 to move. The push block 314 is inserted from the bottom of the support block 312, thereby causing the support block 312 to rise relative to the support seat 311. During the rising process, it will abut against the bottom of the rotary table 100, thereby providing a certain supporting force to the corresponding fixture 500 on the rotary table 100. When the stamping machine is stamping and riveting the parts in the fixture 500, the supporting force provided by the support block 312 can enable the fixture 500 to better cooperate with the stamping machine, thereby ensuring the stamping and riveting between the two parts in the fixture 500, and protecting the rotary table 100 to improve the overall service life of the assembly machine.

[0038] Of course, in order to facilitate the insertion of the push block 314 from the bottom of the support block 312 and to lift it, the bottom of the support block 312 has an inclined lifting surface 312a. The inclined lifting surface 312a makes it easy to push the block 314 into place, thereby facilitating the lifting of the support block 312.

[0039] Please see Figure 7 In this embodiment, in order to achieve automatic unloading and collection of assembled furniture handles, the material handling component 400 includes a lifting cylinder 410, a rotating cylinder 420, and a clamping cylinder 430. The output end of the lifting cylinder 410 is connected to a lifting plate 440, and the rotating cylinder 420 is mounted on the lifting plate 440. The lifting cylinder 410 can drive the rotating cylinder 420 to move up and down. The output end of the rotating cylinder 420 is connected to a rotating plate 450, and the clamping cylinder 430 is mounted on the rotating plate 450. The rotating cylinder 420 can drive the clamping cylinder 430 to rotate. The output end of the clamping cylinder 430 is connected to a gripper 460.

[0040] After the furniture handle in the jig 500 is stamped and riveted at the stamping station 300, the rotary table 100 will rotate the jig 500 again and rotate it to the material handling assembly 400. At this time, the lifting cylinder 410 in the material handling assembly 400 will drive the lifting plate 440 to move upward, which in turn will cause the rotary cylinder 420 to move upward. When the rotary cylinder 420 moves to the set position, it will drive the rotating plate 450 to rotate, which will drive the clamping cylinder 430 to rotate and rotate it to the top of the jig 500. Then, the lifting cylinder 410 drives the rotating cylinder 420 to move downward, thereby keeping the clamping cylinder 430 engaged with the fixture 500. The gripper 460 connected to the clamping cylinder 430 clamps the furniture handle that has been assembled in the fixture 500. After clamping, the lifting cylinder 410 drives the rotating cylinder 420 to move upward again. After moving into position, the rotating cylinder 420 drives the clamping cylinder 430 to rotate and reset. The clamping cylinder 430 then unloads and collects the clamped furniture handle, ultimately achieving automated unloading and improving efficiency.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
