[0025] The features of the present utility model and other related features are further described in detail through the following examples for the understanding of the technicians in the same industry:

[0026] For the convenience of description and understanding, for the description related to position relationship in the present case, such as front, back, up, down, left, right, outside and inside, please refer to the orientation shown in Figure 1 , Figure 2 .

[0027] As Figures 1 to 6As shown, the piano key switch copper sheet assembly machine comprises a rack 100. The rack is used to carry subsequent mechanisms and provides a certain height to facilitate manual feeding and manual monitoring of equipment operation. The first feeding mechanism 1, the material conveying channel 2 connected to the left end of the first feeding mechanism 1, the second feeding mechanism 3, the first feeding mechanism 4, the second feeding mechanism 5, the third feeding mechanism 6, and the discharge chute 7 connected to the end of the material conveying channel 2 are sequentially arranged on the rack 100 from right to left according to the process flow. The left end of the second feeding mechanism 3 is connected to the first feeding mechanism 4, the right end of the third feeding mechanism 6 is connected to the second feeding mechanism 5, and the lower end of the material conveying channel 2 is connected to the material moving mechanism 8.

[0028] In specific implementation, the assembly machine is used to accurately install the first conductive copper sheet 300 and the second conductive copper sheet 400 on the bottom shell 200. The first feeding mechanism 1 is used for feeding the bottom shell 200, the second feeding mechanism 3 is used for feeding the first conductive copper sheet 300, and the third feeding mechanism 6 is used for feeding the second conductive copper sheet 400. The bottom shell 200 is conveyed from the first feeding mechanism 1 to the material conveying channel 2, the first conductive copper sheet 300 is conveyed from the second feeding mechanism 3 to the first feeding mechanism 4 standby, and the second conductive copper sheet 400 is conveyed from the third feeding mechanism 6 to the second feeding mechanism 5 standby. When the bottom shell 200 moves in the material conveying channel 2 by the material moving mechanism 8, when the bottom shell 200 moves to the lower end of the first feeding mechanism 4, the first feeding mechanism 4 takes the first conductive copper sheet 300 waiting in the second feeding mechanism 3 and presses it into the bottom shell 200. After installation is completed, the material moving mechanism 8 continues to drive the bottom shell 200 to continue to move left in the material conveying channel 2. When the bottom shell 200 moves to the lower end of the second feeding mechanism 5, the second feeding mechanism 5 takes the second conductive copper sheet 400 waiting in the third feeding mechanism 6 and presses it into the bottom shell 200. The material moving mechanism 8 pushes the assembled bottom shell 200 into the discharge chute 7, and automatic discharge is completed through the slope of the discharge chute 7.

[0029] The assembly machine breaks through the traditional single-station press-fitting mode, realizes the synchronous circulation of the bottom shell 200, the first conductive copper sheet 300 and the second conductive copper sheet 400 through linear arrangement, and improves the production rhythm. At the same time, it effectively ensures the reliable connection of the first conductive copper sheet 300 and the second conductive copper sheet 400 with the bottom shell 200. The material moving and press-fitting actions are decoupled, the idle time of the equipment is eliminated through timing optimization, and the theoretical production capacity is maximized.

[0030] It needs to be explained that in the implementation, the presence or absence of the object is detected by setting multiple induction switches, and the in-place condition of the object is detected, so as to trigger the action of each mechanism or change the state of each mechanism, thereby realizing the cyclic work of each mechanism. The related content here is a known technology in the art, and the setting position and number of each induction switch are not described one by one. In the implementation, those skilled in the art can adaptively set the corresponding induction switch to realize the linkage between each mechanism according to the common sense in the art and the mechanisms in the case.

[0031] As shown in Figures 1-3 The first feeding mechanism 1 includes a first vibrating disc, a first feeding guide rail 11 connected to the left end of the first vibrating disc, and a first linear vibrator 12 installed at the lower end of the first feeding guide rail 11. The upper end of the first feeding guide rail 11 is connected with a first baffle 13, and the left end of the first feeding guide rail 11 is connected with the material conveying channel 2.

[0032] The first vibrating disc (not shown in the figure) of the case can adopt a common vibrating disc in the art, which is not the focus of the utility model. In order to facilitate the description combined with the drawings, it is not described in detail in the case, and the user can select the appropriate first vibrating disc according to the actual situation. The first vibrating disc is the starting device for feeding the bottom shell 200. The first vibrating disc uses its vibration function to arrange the disordered bottom shell 200 in a certain direction and attitude, so that the bottom shell 200 can enter the first feeding guide rail 11 in a certain direction and attitude, realize the automatic orientation of the bottom shell 200, provide ordered materials for subsequent conveying and assembly, improve the efficiency and accuracy of feeding, and avoid the tedious process of manual sorting.

[0033] In the implementation, the first linear vibrator 12 is used to receive the bottom shell 200 from the first vibrating disc, provide a conveying channel for the bottom shell 200, and make the bottom shell 200 slide along the first feeding guide rail 11. The first linear vibrator 12 is used for vibration feeding of the bottom shell 200 in the first feeding guide rail 11, until the bottom shell 200 is conveyed to the first feeding mechanism 4. The first feeding guide rail 11 is adapted to the shape of the bottom shell 200, so that the bottom shell 200 can smoothly slide in the first feeding guide rail 11. The first baffle 13 can effectively prevent the displacement or disengagement of the bottom shell 200 from the first feeding guide rail 11 during the movement of the bottom shell 200 driven by the first linear vibrator 12 in the first feeding guide rail 11, and ensure the stability of the bottom shell 200 transportation.

[0034] Continuing to refer to Figures 1-3As shown, the material conveying channel 2 comprises a bottom plate 21, side plates 22 connected to both sides of the bottom plate 21, and a second baffle plate 23 connected to the upper end of one of the side plates 22. The bottom plate 21 and the two side plates 22 form a feeding channel 24 therebetween, and the second baffle plate 23 is provided with a relief hole 231. The second baffle plate 23 can effectively prevent displacement or disengagement from the guide rail during the movement of the bottom shell 200 in the feeding channel 24 driven by the material moving mechanism 8, thereby ensuring the stability of the transportation of the bottom shell 200. The relief hole 25 is used for the operation of the first feeding mechanism 4 and the second feeding mechanism 5 to avoid interference, and also serves as a precise positioning function to reduce the positioning time, thereby accurately and quickly loading the conductive copper sheet into the bottom shell 200 in the material conveying channel 2.

[0035] With reference to the drawings and Figures 1-3 As shown, the second feeding mechanism 3 comprises a second vibrating disc, a second feeding guide rail 31 connected to the left end of the second vibrating disc, and a second linear vibrator 32 installed at the lower end of the second feeding guide rail 31. The upper end of the second feeding guide rail 31 is connected with a third baffle plate 33, and the left end of the second feeding guide rail 31 is connected with the first feeding mechanism 4.

[0036] The third baffle plate 33 can effectively prevent displacement or disengagement from the second feeding guide rail 31 during the movement of the first conductive copper sheet 300 in the second feeding guide rail 31 driven by the second linear vibrator 32, while ensuring the correct feeding direction of the first conductive copper sheet 300 and guaranteeing the accuracy and stability of the transportation of the first conductive copper sheet 300.

[0037] The working principle and function of the second feeding mechanism 3 in the present case can be referred to the description of the first feeding mechanism 1 in the present case. Although the structures of the two are different, the working principles and functions are similar. The difference between the two lies in that the structure of the second feeding guide rail 31 and the third baffle plate 33 need to be modified according to different first conductive copper sheets 300 to ensure the stability and correct feeding direction of the first conductive copper sheet 300.

[0038] With reference to the drawings and Figures 1-4 As shown, the first feeding mechanism 4 in the present case comprises a first fixed support 41, a first telescopic cylinder 42 installed on the first fixed support 41, and a first material receiving table 43 fixedly connected to the lower end of the first telescopic cylinder 42. The first material receiving table 43 is slidingly connected with the first fixed support 41 through a first sliding seat 44. The first telescopic cylinder 42 is provided with a first top rod 45 capable of following the telescopic movement of the first telescopic cylinder 42. The first material receiving table 43 comprises a first positioning head 431, a first material receiving seat 432, and a first material ejecting channel 433 extending through the first material receiving table 433. The first top rod 45 downwardly penetrates the first material ejecting channel 433.

[0039] In implementation, the first telescopic cylinder 42 is a double-shaft telescopic cylinder, and its telescopic shaft can pass through the front connecting plate of the first telescopic cylinder 42, so that after the first sliding seat 44 stops sliding, it can continue to drive the first ejector rod 45 to descend through the rear connecting plate. The sliding distance of the first sliding seat 44 on the first fixed support 41 is set according to the length of the sliding rail, and the first positioning head 431 plays a positioning role to accurately position and fix the bottom shell 200 in the material conveying channel 2, and ensure the accurate pressing position of the first conductive copper sheet 300.

[0040] As described above, when the first conductive copper sheet 300 is assembled, the first conductive copper sheet 300 is conveyed from the second feeding mechanism 3 to the first feeding seat 432 of the first feeding table 43 and placed in the first ejecting channel 433, and the first telescopic cylinder 42 is started to drive the first feeding table 43 to slide downward with the first sliding seat 44 on the first fixed support 41. When the first sliding seat 44 slides to the lowermost end of the sliding rail, the first positioning head 431 presses the bottom shell 200 in the material conveying channel 2, and the first sliding seat 44 stops sliding. The first telescopic cylinder 42 continues to move downward until the first conductive copper sheet 300 in the first ejecting channel 433 is pressed and installed to pass through the first positioning head 431 and into the bottom shell 200 in the material conveying channel 2, and then the installation is completed, and then each mechanism is reset, and the reciprocating motion is repeated.

[0041] Referring to Figures 1-5 As shown in the figure, the second feeding mechanism 5 includes a second fixed support 51, a second telescopic cylinder 52 installed on the second fixed support 51, and a second feeding table 53 fixedly connected to the lower end of the second telescopic cylinder 52. The second feeding table 53 is slidingly connected to the second fixed support 51 through a second sliding seat 54. The second telescopic cylinder 52 is provided with a second ejector rod 55 capable of following the telescopic movement of the second telescopic cylinder 52. The second feeding table 53 includes a second positioning head 531, a second feeding seat 532, and a second ejecting channel 533 passing through the second feeding table 53. The second ejector rod 55 downwardly passes through the second ejecting channel 533 movably arranged in the second ejecting channel 533.

[0042] In this case, the working principle and role of the second feeding mechanism 5 can be referred to the corresponding description of the first feeding mechanism 4 in this case. Although the structures of the two are different, the working principles and roles are similar. It should be noted that the difference between the two is that the second telescopic cylinder 52 is a single-shaft telescopic cylinder, which is slidingly connected to the second fixed support 51 through the second sliding seat 54. Users can improve the structure of the second feeding table 53 according to the structure of the second conductive copper sheet 400, such as improving the structures of the second positioning head 531, the second feeding seat 532, and the second ejecting channel 533, and increasing some fixing seats, so as to realize the use of the single-shaft telescopic cylinder to drive the second feeding table 53 and the second ejector rod 55, and save material cost.

[0043] Referring to Figures 1-3 As shown in the drawings, the third feeding mechanism 6 comprises a third vibrating disc, a third feeding guide rail 61 connected to the left end of the third vibrating disc, and a third linear vibrator 62 installed at the lower end of the third feeding guide rail 61. The upper end of the third feeding guide rail 61 is connected with a fourth baffle 63, and the right end of the third feeding guide rail 61 is connected with the second feeding mechanism 5.

[0044] In the present case, the working principle and function of the third feeding mechanism 6 are the same as those of the first feeding mechanism 1 and the second feeding mechanism 3, which are described in the present case. Although the structures of the three are different, the working principles and functions are similar. It should be noted that the difference is that the third feeding mechanism 6 of the present case needs to modify the structure of the third feeding guide rail 61 and the fourth baffle 63 according to different second conductive copper sheets 400 to ensure the stability and correctness of the feeding direction of the second conductive copper sheet 400.

[0045] As shown in the drawings, Figures 1-6 The material moving mechanism 8 of the present case comprises a linear module 81, a material moving bracket 82 connected to the front end of the linear module 81, and a jacking cylinder 83 connected to the lower end of the material moving bracket 82. The material moving bracket 82 comprises a material moving rod 821 which is movably arranged upward in the material conveying channel 2.

[0046] In specific implementation, the jacking cylinder 83 is used to drive the material moving bracket 82 to move up and down, so that the material moving rod 821 extends into and out of the material conveying channel 2. The linear module 81 is used to drive the material moving bracket 82 to move left and right in the transverse direction. When it is necessary to move the material, the jacking cylinder 83 is started to drive the material moving bracket 82 to rise, so that the material moving rod 821 of the material moving bracket 82 is inserted into the material conveying channel 2 and abuts against the bottom shell 200 at the corresponding position in the material conveying channel 2. Then, the linear module 81 drives the material moving bracket to move left to convey the bottom shell 200 to the corresponding position. After the conveying is completed, the jacking cylinder 83 is reset, the material moving bracket 82 is lowered, and the material moving rod 821 is withdrawn from the material conveying channel 2. Then, the linear module 81 drives the material moving bracket 82 to move right to reset, and the reciprocating action is repeated.

[0047] Preferably, in the present case, three material moving rods 821 are provided. The three material moving rods 821 are respectively used for moving the bottom shell 200 from the first feeding mechanism 1 to the material conveying channel 2, moving in the material conveying channel 2 to the first loading mechanism 4, and moving in the material conveying channel 2 from the first loading mechanism 4 to the second loading mechanism 5. In specific implementation, if more conductive copper sheets need to be assembled, more loading mechanisms need to be provided, which makes the material conveying channel 2 longer. If the material conveying channel 2 is too long, the user can choose to provide more material moving rods 821 or directly provide more material moving mechanisms 8 to cooperate with the material moving, in addition, the material moving can also be assisted by increasing the air cylinder. It should be noted that, in order to further improve the material moving efficiency, a material moving air cylinder is provided between the first feeding mechanism 1 and the material conveying channel 2, and a material moving air cylinder is also provided between the first loading mechanism 4 and the second loading mechanism 5.

[0048] As described above, the material moving mechanism 8 of the present case cooperates with the linear module 81, the material moving bracket 82 and the jacking air cylinder 83 to improve the accuracy and stability of moving the bottom shell 200 in the material conveying channel 2, and breaks through the limitation of traditional single-rod long-distance moving, and improves the positioning accuracy and moving efficiency through segmented control.

[0049] Specifically, as shown in Figures 1-6 The linear module 81 of the present case includes symmetrical fixed seats 811, a motor 812, and guide rods 813 and a screw rod 814 connected between the two fixed seats 811. The screw rod transmission has high transmission accuracy and efficiency, and can realize accurate displacement control, so that the material moving bracket 82 can accurately reach the specified position, ensuring the accuracy of moving the bottom shell between stations. Two guide rods 813 are arranged above and below, and the screw rod 814 is arranged between the upper and lower guide rods 813. The design of the double guide rods 813 increases the stability and reliability of the movement of the material moving bracket 82, reduces the frictional resistance in the movement process, improves the smoothness of the movement, and also helps to improve the accuracy of the material moving. The rear end of the material moving bracket 82 is connected to the guide rods 813 and the screw rod 814, and the material moving bracket 82 can reciprocate left and right along the guide rods 813 and the screw rod 814 under the drive of the motor 812. In specific implementation, the motor 812 is a servo motor, which can realize accurate speed and position control, so that the moving speed and position of the material moving bracket 82 can be adjusted according to actual needs, improving the accuracy and efficiency of the material moving, and also adapting to different working tempos.

[0050] As described above, the design of the linear module 81 enables the material moving mechanism 8 to achieve precise and stable linear motion, improving the accuracy and efficiency of the bottom shell moving between stations. Through precise control of the motor 812, the material moving bracket 82 can move at a preset speed and position, reducing manual intervention and labor intensity. The cooperation of the double guide rod 813 and the screw rod 814 ensures the stability and straightness of the movement of the material moving bracket 82, reduces the movement error, and improves the assembly quality of the product. At the same time, this structural design has high reliability and durability, reduces the maintenance cost and downtime of the equipment, and improves the production efficiency.
