Description

Technical Field

[0001] The present invention relates to the field of intercom assembly equipment, and particularly to an automatic intercom antenna assembly machine. Background Art

[0002] Intercoms are mainly used in industries such as public security, civil aviation, transportation, water conservancy, railways, manufacturing, construction, and services. They are mainly used for communication and command and dispatch among group members, and are used to improve communication efficiency and the rapid response ability to handle emergencies. As an important part of the intercom, the intercom antenna is used to receive and transmit signals. The electromagnetic wave signals between intercoms are mainly received and transmitted through the intercom antenna. The intercom antenna mainly includes a sleeve connected to the intercom body, an antenna core installed in the sleeve, and a cap fixed to the head of the antenna sleeve. At present, the assembly of the intercom antenna sleeve and the cap mainly relies on manual operation. Specifically, after manually applying glue to the inner wall of the cap, the cap is then connected to the head of the antenna sleeve. However, the manual glue application method has the problem of uneven application, which affects the sealing performance at the connection between the cap and the antenna sleeve. In the case of poor sealing, moisture and dust are likely to enter the antenna interior, thereby affecting the performance and service life of the intercom. In addition, the manual assembly efficiency is low and the labor intensity is high, thus reducing the production efficiency of the intercom antenna. At the same time, when the cap is inserted into the head of the antenna rod, due to the uneven pressing force applied during manual assembly, the connection between the cap and the antenna sleeve is likely to become loose, affecting the overall quality and stability of the intercom antenna.

[0003] Therefore, this case aims to provide an automatic intercom antenna assembly machine that is easy to use, has high assembly efficiency and a long service life. Summary of the Invention

Detailed implementation manners

[0019] To make the implementation manners of the present invention clear, the technical solutions in the implementation manners of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation manners of the present invention. Obviously, the described implementation manners are part of the implementation manners of the present invention, rather than all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0021] At present, the assembly of the antenna sleeve and cap of the walkie-talkie mainly relies on manual operation. Specifically, after manually applying glue to the inner wall of the cap, the cap is then connected to the head of the antenna sleeve. However, the manual glue application method has the problem of uneven application, which affects the sealing performance at the connection between the cap and the antenna sleeve. In the case of poor sealing, moisture and dust are likely to enter the antenna, thereby affecting the performance and service life of the walkie-talkie. In addition, the manual assembly efficiency is low and the labor intensity is high, thus reducing the production efficiency of the walkie-talkie antenna. At the same time, when the cap is inserted into the head of the antenna rod, due to the uneven pressing force applied during manual assembly, the connection between the cap and the antenna sleeve is prone to looseness, affecting the overall quality and stability of the walkie-talkie antenna. To solve the above technical problems, the following technical solutions are proposed in this case: Referring to Figures 1 to 16 As shown, an automatic assembly machine for walkie-talkie antennas, its structure includes: a frame 1, on which there is an antenna indexing turntable 2. Four sleeve fixing seats 21 are evenly arranged at equal intervals around the antenna indexing turntable 2. A sleeve feeding unit 3, a cap assembly unit 4, a cap detection unit 5, and a finished product discharging unit 6 are arranged on the frame 1 and are sequentially arranged around the antenna indexing turntable 2 along the processing direction. The cap assembly unit 4 includes a cap indexing turntable 41 fixed between the antenna indexing turntable 2 and the top of the frame 1. Four cap fixing seats 42 are evenly arranged at equal intervals on the cap indexing turntable 41, and a feeding mechanism 7, a glue injection mechanism 8, and an assembly mechanism 9 are sequentially arranged around the cap indexing turntable 41 along the rotation direction of the cap indexing turntable 41. The glue injection mechanism 8 includes a column 81 fixed to the top of the frame 1. A first bracket 82 is provided on the column 81. A glue injection cylinder 83 is vertically installed on the first bracket 82. The output shaft of the glue injection cylinder 83 is fixed with a glue injector 84 located directly above the cap fixing seat 42. The assembly mechanism 9 includes a pressing cylinder 91 fixed to the top of the column 81. The output shaft of the pressing cylinder 91 is provided with a pressing plate 92 for pressing the top of the antenna sleeve. A second bracket 93 is arranged inside the frame 1 below the coincidence point of the sleeve fixing seat 21 and the cap fixing seat 42. A lifting cylinder 94 is provided on the second bracket 93. The output shaft of the lifting cylinder 94 is coaxially connected with a push rod 95. A clamping mechanism 96 for clamping the antenna sleeve is also included. First jacks 411 and second jacks 421 are respectively provided on the cap indexing turntable 41 and the cap fixing seat 42 for the push rod 95 to pass upward to push the cap to be connected to the bottom of the antenna sleeve; Among them, a controller for controlling the operation of the assembly machine is provided on the frame 1 to ensure the smooth progress of the entire assembly process. At the same time, driving mechanisms for driving the intermittent rotation of the antenna indexing turntable 2 and the cap indexing turntable 41 are respectively arranged inside the frame 1. The driving mechanisms, sleeve feeding unit 3, cap detection unit 5, and finished product discharging unit 6 in this embodiment are all prior arts, so they will not be elaborated in detail here; Therefore, during use, first insert the antenna sleeve to be assembled into the sleeve fixing seat 21 near the sleeve feeding unit 3 to ensure stable positioning of the sleeve. Then, the driving mechanism drives the antenna indexing turntable 2 to rotate, pushing the sleeve fixing seat 21 to rotate to the side of the cap assembling unit 4. Then, glue is injected into the cap, and at the same time, the cap is connected to the bottom of the antenna sleeve. After the assembly is completed, the driving mechanism continues to drive the antenna indexing turntable 2 to rotate, turning the sleeve fixing seat 21 to the side of the cap detection unit 5, and the sensor is used to detect whether the cap is installed in place. Subsequently, the driving mechanism drives the antenna indexing turntable 2 to rotate again, making the sleeve fixing seat 21 rotate to the side of the finished product discharging unit 6, so as to take out the assembled antenna and complete the assembly process; Specifically, the caps are sequentially conveyed to the cap fixing seats 42 by the feeding mechanism 7. Then, the driving mechanism drives the cap indexing turntable 41 to rotate, making the cap fixing seats 42 rotate to the side of the glue injection mechanism 8. At this time, the glue injector 84 is aligned with the caps on the cap fixing seats 42. The glue injection cylinder 83 is then activated, driving the glue injector 84 to move downward to inject glue into the caps quantitatively and evenly. After the glue injection operation is completed, the glue injection cylinder 83 drives the glue injector 84 to move upward and reset. Then, the driving mechanism continues to drive the cap indexing turntable 41 to rotate, turning the cap fixing seats 42 to the side of the assembling mechanism 9. At this time, the cap fixing seats 42 are exactly below the sleeve fixing seats 21, and the antenna sleeve and the cap are on the same vertical line. The clamping mechanism 96 first clamps and fixes the antenna sleeve to ensure its stability. Then, the pressing cylinder 91 drives the pressing plate 92 to move downward, making the bottom of the pressing plate 92 closely abut against the top of the antenna sleeve, so as to prevent the antenna sleeve from moving up and down during the assembly process. At the same time, the jacking cylinder 94 is activated, driving the push rod 95 to pass through the first jack 411 and the second jack 421, jacking up the caps with glue injection completed on the cap fixing seats 42, so that the caps are inserted into the bottom of the antenna sleeve for connection. After the connection is completed, the jacking cylinder 94 drives the push rod 95 to move downward and reset. At the same time, the pressing cylinder 91 drives the pressing plate 92 to move upward, and the clamping mechanism 96 releases the clamping of the antenna sleeve. Finally, the automatic and precise assembly of the antenna sleeve and the cap is realized, which not only reduces the labor intensity of workers, improves the efficiency of antenna assembly, but also ensures that the glue injection process of the cap is uniform and precise during assembly, improves the sealing performance at the connection between the cap and the antenna sleeve, and guarantees the quality and reliability of the antenna product; It should be noted that the glue injector 84 is connected to an external container for storing glue through a conduit. During the glue injection process, the glue flows into the glue injector 84 through the conduit and is driven by a pump body to ensure that the glue is injected into the cap stably and evenly.

[0022] Meanwhile, the cap fixing seat 42 is provided with a positioning groove 422 for the cap to be snapped and fixed. To ensure that the cap remains fixed during the rotation of the cap fixing seat 42 and prevent it from detaching due to the centrifugal force acting on the cap fixing seat 42, and at the same time ensure that the cap always remains at the center of the positioning groove 422, a limiting device 43 for clamping the cap is provided inside the cap fixing seat 42; the limiting device includes a first limiting arm 431 and a second limiting arm 432 that are rotatably connected to the inside of the cap fixing seat 42 through a pin shaft. One end of the first limiting arm 431 and the second limiting arm 432 are cross - arranged, and the other end extends towards both sides of the positioning groove 422. It also includes a transmission mechanism for driving the first limiting arm 431 and the second limiting arm 432 to clamp and release; thus, when the cap is conveyed to the positioning groove 422 by the feeding mechanism 7, the transmission mechanism drives the first limiting arm 431 and the second limiting arm 432 to rotate inwards around the pin shaft, so that the end parts of the first limiting arm 431 and the second limiting arm 432 are respectively snapped into both sides of the positioning groove 422 simultaneously to tighten the cap, realizing self - centering clamping and fixing of the cap in the positioning groove 422. At the same time, it prevents the cap from falling off due to centrifugal force, ensures that the cap always remains fixed at the center position of the positioning groove 422, effectively prevents the loosening or detachment of the cap, and also ensures that the cap and the antenna sleeve are always on the same vertical line during assembly, facilitating installation and improving the overall assembly accuracy and efficiency; After the cap and the antenna sleeve are assembled, the transmission mechanism drives the first limiting arm 431 and the second limiting arm 432 to rotate outwards around the pin shaft, so that the end parts of the first limiting arm 431 and the second limiting arm 432 are separated from the positioning groove 422, thus facilitating the feeding mechanism 7 to smoothly convey the next cap into the positioning groove 422; The second jack 421 is at the bottom of the positioning groove 422; Specifically, both ends of the cross - arranged first limiting arm 431 and second limiting arm 432 are provided with first guide chutes 433. The transmission mechanism includes a transmission rod 434 passing through the overlapping part of the two first guide chutes 433. Between the cap indexing turntable 41 and the top of the frame 1, there is an inner ring seat 435 coaxially arranged with the cap indexing turntable 41. An annular slide rail 436 is formed on the inner ring seat 435. The other end of the transmission rod 434 vertically passes down through the cap fixing seat 42 and the cap indexing turntable 41 and cooperates with the annular slide rail 436. The cap indexing turntable 41 and the cap fixing seat 42 are respectively provided with second guide chutes 412 and third guide chutes 423 for the annular slide rail 436 to drive the transmission rod 434 to slide back and forth; The annular slide rail 436 is coaxially arranged with the inner ring seat 435, and the annular slide rail 436 is composed of a first - stage slide rail and a second - stage slide rail. The first - stage slide rail extends from behind the feeding mechanism 7 to behind the assembling mechanism 9, and the second - stage slide rail extends from behind the assembling mechanism 9 to behind the feeding mechanism 7. The diameter of the first - stage slide rail is larger than that of the second - stage slide rail, and a smooth transition connection is adopted between the first - stage slide rail and the second - stage slide rail; Therefore, when the cap is conveyed to the positioning groove 422 by the feeding mechanism 7, as the cap indexing turntable 41 drives the cap fixing seat 42 to rotate from the feeding mechanism 7 to the glue injection mechanism 8, the transmission rod 434 enters the first-section slide rail from the second-section slide rail, and at the same time moves outward along the second guide chute 412 and the third guide chute 423. At this time, the transmission rod 434 slides synchronously along the first guide chute 433, prompting the first limiting arm 431 and the second limiting arm 432 to rotate inward around the pin shaft, fixing the cap in the positioning groove, thereby ensuring stable and accurate positioning of the cap during rotation and completing the effective fixation of the cap; After the cap assembly is completed, as the cap indexing turntable 41 drives the cap fixing seat 42 to rotate from the assembly mechanism 9 to the feeding mechanism 7, the transmission rod 434 enters the second-section slide rail from the first-section slide rail. At this time, it moves inward along the second guide chute 412 and the third guide chute 423, and at the same time the transmission rod 434 slides synchronously under the guidance of the first guide chute 433, prompting the first limiting arm 431 and the second limiting arm 432 to rotate outward around the pin shaft, so that the ends of the first limiting arm 431 and the second limiting arm 432 are separated from the positioning groove 422, thereby facilitating the feeding mechanism 7 to convey the cap into the positioning groove 422.

[0023] In order to ensure that the pressing force applied during the assembly process is uniform and effectively prevent loosening at the connection between the cap and the antenna sleeve, a lateral pressing device 44 is further provided in the cap fixing seat 42 on the positioning groove 422. The lateral pressing device 44 includes an annular base 441. A number of clamping plates 442 are evenly distributed at equal intervals in a ring shape on the annular base 441. An expansion joint is formed between adjacent two clamping plates 442. The clamping plates 442 enclose a frustum shape with a narrow upper part and a wide lower part. A slideway 424 for the annular base 441 to slide up and down is provided in the cap fixing seat 42. A guide cylinder 425 that slidably cooperates with the clamping plates 442 is provided at the top of the cap fixing seat 42. The guide cylinder 425 is a hollow frustum shape with a narrow upper part and a wide lower part. A spring 443 sleeved on the outside of the clamping plates 442 is provided between the slideway 424 and the annular base 441. A convex block 951 for pushing the annular base 441 to slide up and down in the slideway 424 is provided on the side wall of the push rod 95. Through grooves for the convex block 951 to pass through are formed in both the first jack 411 and the second jack 421; Specifically, the jacking cylinder 94 drives the push rod 95 to move upward through the first jack 411 and the second jack 421, first jacking up the cap to connect it to the bottom of the antenna sleeve. During the upward movement of the push rod 95, when the convex block 951 abuts against the bottom of the annular base 441, the convex block 951 pushes the annular base 441 to move upward along the slideway 424. Furthermore, the annular base 441 squeezes the spring 443 and drives the clamping plate 442 to move upward synchronously. Since the guiding cylinder 425 is a hollow frustum shape that is narrower at the top and wider at the bottom, as the annular base 441 moves upward, the clamping plate 442 gradually squeezes inward, thereby forming a uniform circumferential pre-tightening force on the side wall of the cap. This not only effectively improves the initial bonding strength between the side of the cap and the antenna sleeve but also enhances the connection stability at the joint between the cap and the antenna sleeve; After assembly, the push rod 95 moves downward to reset. At this time, the spring 443 pushes the annular base 441 to move downward along the slideway 424 to reset, realizing the separation of the clamping plate 442 from the cap and causing the clamping plate 442 to reset and expand.

[0024] Ball bearings 426 are sleeved on the inner wall of the positioning groove 422 and the inner sides of the first limiting arm 431 and the second limiting arm 432 extending toward the positioning groove 422. Furthermore, when the cap is jacked upward from the positioning groove 422 to connect to the bottom of the antenna sleeve, the friction between the cap and the cap fixing seat 42 is reduced.

[0025] The glue injector 84 includes a glue injection tube 841 and a glue application head 842 provided at the bottom of the glue injection tube 841. A plurality of glue outlet holes are formed on the side wall and the bottom of the glue application head 842. Furthermore, when the glue injection cylinder 83 pushes the glue injector 84 downward, the glue application head 842 evenly applies a fixed amount of glue to the inner side wall and the bottom wall of the cap through the glue outlet holes, ensuring a firm and reliable connection between the cap and the antenna sleeve, significantly enhancing the connection stability and durability at the joint between the cap and the antenna sleeve, avoiding problems such as loosening or detachment caused by poor connection, and further improving the overall quality and service life of the antenna.

[0026] The clamping mechanism 96 includes a third bracket 961 fixed to the top of the frame 1. A sliding cylinder 962 is provided on the third bracket 961 and faces downward at the coincidence of the sleeve fixing seat 21 and the cap fixing seat 42. The output end of the sliding cylinder 962 is provided with a clamping cylinder 963 for clamping the antenna sleeve. During use, the sliding cylinder 962 is used to push the clamping cylinder 963 forward, prompting the jaws of the clamping cylinder 963 to align with the antenna sleeve. Furthermore, the antenna sleeve is clamped and fixed by the clamping cylinder 963, ensuring that the antenna sleeve always maintains a firm fixed state during the assembly process, preventing problems such as loosening or position deviation from affecting the quality of subsequent operations or connections.

[0027] The feeding mechanism 7 includes a cap vibrating bowl 71 on one side of the frame 1 and a feeding guide rail 72 connected to the discharge port of the cap vibrating bowl 71. The other end of the feeding guide rail 72 is aligned with the positioning groove 422 of the cap fixing seat 42. It also includes a pushing cylinder 73 fixed on the frame 1 for pushing the cap from the feeding guide rail 72 into the positioning groove 422. During use, the cap vibrating bowl 71 conveys the cap to the feeding guide rail 72 and ensures its smooth flow along the guide rail. When the cap reaches the end of the feeding guide rail 72, the pushing cylinder 73 is activated to push the cap into the positioning groove 422 in the cap fixing seat 42, completing the automatic feeding process of the cap.

[0028] An opening groove for the cap to pass upward is formed inside the annular base 441 and within the frustum shape formed by the clamping plate 442. Thus, when the push rod 95 pushes the cap upward, the cap can easily be connected to the bottom of the antenna sleeve through the opening groove.

[0029] A locking step for fixing the cap is formed at the bottom of the positioning groove 422. After the cap enters the positioning groove 422, the locking step can accurately lock the cap, stably fixing it in the groove and ensuring that the cap is centered and aligned.
