Description

Technical Field

[0001] The invention relates to the field of walkie-talkie assembly equipment, in particular to an automatic walkie-talkie antenna assembly machine. Background Art

[0002] Walkie-talkies are mainly used in public security, civil aviation, transportation, water conservancy, railways, manufacturing, construction, service and other industries. They are mainly used for communication and command and dispatch between team members, and are used to improve communication efficiency and enhance the ability to quickly respond to emergencies. As an important component of walkie-talkies, walkie-talkie antennas are used to receive and transmit signals. The electromagnetic wave signals between walkie-talkies are mainly received and transmitted through the walkie-talkie antenna.

[0003] The walkie-talkie antenna mainly includes a sleeve connected to the walkie-talkie body, an antenna core installed in the sleeve, and a cap fixed to the head of the antenna sleeve. Currently, the assembly of the walkie-talkie antenna sleeve and the cap mainly relies on manual operation. Specifically, glue is applied to the inner wall of the cap manually, and then the cap is connected to the head of the antenna sleeve. However, the manual gluing method has the problem of uneven application, which affects the sealing performance of the connection between the cap and the antenna sleeve. When the seal is not tight, moisture and dust can easily enter the inside of the antenna, thereby affecting the performance and service life of the walkie-talkie. In addition, manual assembly is inefficient and labor-intensive, thereby reducing the production efficiency of the walkie-talkie antenna. At the same time, when the cap is inserted into the head of the antenna pole, the connection between the cap and the antenna sleeve is easy to loosen due to the uneven pressing force applied during manual assembly, affecting the overall quality and stability of the walkie-talkie antenna.

DETAILED DESCRIPTION

[0037] All embodiments of the present invention are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as referring to the purpose, technical solutions and advantages of the methods. To be clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work indicate or imply relative importance or implicitly indicate the number of indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0039] Currently, the assembly of walkie-talkie antenna sleeves and caps mainly relies on manual operation. Specifically, glue is applied to the inner wall of the cap manually and 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 of the connection between the cap and the antenna sleeve. If the seal is not tight, moisture and dust can easily enter the interior of the antenna, thereby affecting the performance and service life of the walkie-talkie. In addition, manual assembly is inefficient and labor-intensive, thereby reducing the production efficiency of walkie-talkie antennas. At the same time, when the cap is inserted into the head of the antenna pole, the uneven pressing force applied during manual assembly causes the connection between the cap and the antenna sleeve to loosen easily, affecting the overall quality and stability of the walkie-talkie antenna. In order to solve the above technical problems, this case proposes the following technical solutions:

[0040] Reference Figures 1 to 16As shown, an automatic assembly machine for walkie-talkie antennas comprises: a frame 1, on which an antenna indexing turntable 2 is provided, on which four sleeve fixing seats 21 are evenly and equidistantly provided 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 sequentially arranged around the antenna indexing turntable 2 along the processing direction, the cap assembly unit 4 comprises 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 and equidistantly provided 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 comprises a column 81 fixed to the top of the frame 1, the column A first bracket 82 is provided on 81, and 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 just above the cap fixing seat 42; the assembly mechanism 9 includes a pressing cylinder 91 fixed to the top of the column 81, and 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 provided in the frame 1 below the coincidence point of the sleeve fixing seat 21 and the cap fixing seat 42, and a lifting cylinder 94 is provided on the second bracket 93. The output shaft of the lifting cylinder 94 is coaxially connected to a push rod 95, and also includes a clamping mechanism 96 for clamping the antenna sleeve. The cap indexing turntable 41 and the cap fixing seat 42 are respectively provided with a first hole 411 and a second hole 421 for the push rod 95 to pass upward to push the cap to connect with the bottom of the antenna sleeve;

[0041] Among them, the frame 1 is provided with a controller for controlling the operation of the assembly machine to ensure the smooth progress of the entire assembly process. At the same time, the frame 1 is provided with a driving mechanism for driving the antenna indexing turntable 2 and the cap indexing turntable 41 to intermittently rotate. The driving mechanism, the sleeve feeding unit 3, the cap detection unit 5, and the finished product discharge unit 6 in this embodiment are all existing technologies and are not described in detail here.

[0042] Therefore, when in use, the antenna sleeve to be assembled is first inserted into the sleeve fixing seat 21 near the side of the sleeve feeding unit 3 to ensure that the sleeve is firmly positioned. Then, the driving mechanism drives the antenna indexing turntable 2 to rotate, and pushes the sleeve fixing seat 21 to rotate to the side of the cap assembly unit 4, and then injects glue into the cap, and at the same time connects the cap 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, and rotates the sleeve fixing seat 21 to the side of the cap detection unit 5. The sensor detects whether the cap is installed in place, and then the driving mechanism drives the antenna indexing turntable 2 to rotate again, so that the sleeve fixing seat 21 rotates to the side of the finished product discharging unit 6, thereby taking out the assembled antenna and completing the assembly process.

[0043] Specifically, the caps are transported to the cap fixing seat 42 in sequence through the feeding mechanism 7, and then the cap indexing turntable 41 is driven to rotate by the driving mechanism, so that the cap fixing seat 42 is rotated to the side of the glue injection mechanism 8. At this time, the glue injector 84 is aligned with the cap on the cap fixing seat 42, and the glue injection cylinder 83 is started, driving the glue injector 84 to move downward, and injecting glue into the inside of the cap in a quantitative and uniform manner. After the glue injection operation is completed, the glue injection cylinder 83 drives the glue injector 84 to move upward and reset, and then the driving mechanism continues to drive the cap indexing turntable 41 to rotate, and rotates the cap fixing seat 42 to the side of the assembly mechanism 9. At this time, the cap fixing seat 42 is just below the sleeve fixing seat 21, and the antenna sleeve and the cap are on the same vertical line. The antenna sleeve is first clamped and fixed by the clamping mechanism 96 to ensure its stability, and then the pressing cylinder 91 drives the pressure plate 92 moves downward, so that the bottom of the pressure plate 92 is close to the top of the antenna sleeve, thereby preventing the antenna sleeve from moving up and down during the assembly process. At the same time, the lifting cylinder 94 is started, driving the push rod 95 to pass through the first hole 411 and the second hole 421, and lifting the cap on the cap fixing seat 42 that has been glued upward, so that the cap is inserted into the bottom of the antenna sleeve for connection. After the connection is completed, the lifting cylinder 94 drives the push rod 95 to move down and reset, and at the same time, the pressing cylinder 91 drives the pressure plate 92 to move upward, and the clamping mechanism 96 releases the clamping of the antenna sleeve, finally realizing the automatic and precise assembly of the antenna sleeve and the cap, which not only reduces the labor intensity and improves the efficiency of antenna assembly, but also ensures that the glue injection process of the cap is uniform and accurate during assembly, improves the sealing of the connection between the cap and the antenna sleeve, and ensures the quality and reliability of the antenna product.

[0044] It should be noted that the glue injector 84 is connected to an external container for glue through a conduit. During the glue injection process, the glue flows into the glue injector 84 through the conduit and is driven by the pump body to ensure that the glue is stably and evenly injected into the cap.

[0045] At the same time, the cap fixing seat 42 is provided with a positioning groove 422 for the cap to be clamped and fixed. In order to ensure that the cap remains fixed during the rotation of the cap fixing seat 42 and avoid the cap fixing seat 42 from being separated due to the centrifugal force, and at the same time ensure that the cap is always kept in the center of the positioning groove 422, a limiting device 43 for clamping the cap is provided in the cap fixing seat 42; the limiting device includes a first limiting arm 431 and a second limiting arm 432 which are rotatably connected to 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 toward both sides of the positioning groove 422, and also includes a limiting device 43 that drives the first limiting arm 431 and the second limiting arm 432 to move in a predetermined direction. 2. Transmission mechanism for clamping and loosening; when the cap is transported to the positioning groove 422 by the feeding mechanism 7, the first limiting arm 431 and the second limiting arm 432 are driven by the transmission mechanism to rotate inward around the pin axis, so that the ends of the first limiting arm 431 and the second limiting arm 432 are respectively and synchronously clamped into the two sides of the positioning groove 422, and the cap is tightened, so as to realize self-centering clamping and fixing of the cap in the positioning groove 422, and at the same time prevent the cap from falling off due to centrifugal force, ensure that the cap is always fixed in the center position of the positioning groove 422, effectively prevent the cap from loosening or detaching, and ensure that the cap and the antenna sleeve are always in the same vertical line during assembly, which is convenient for installation and improves the overall assembly accuracy and efficiency;

[0046] When 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 outward around the pin axis, 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 smoothly deliver the next cap to the inside of the positioning groove 422;

[0047] The second plug hole 421 is located at the bottom of the positioning groove 422;

[0048] Specifically, one end of the first limiting arm 431 and the second limiting arm 432 that are cross-arranged is provided with a first guide slot 433, and the transmission mechanism includes a transmission rod 434 that passes through the overlap of the two first guide slots 433, and an inner ring seat 435 that is coaxial with the cap indexing turntable 41 is provided between the cap indexing turntable 41 and the top of the frame 1, and an annular slide rail 436 is formed on the inner ring seat 435, and the other end of the transmission rod 434 vertically passes through the cap fixing seat 42 and the cap indexing turntable 41 downward and cooperates with the annular slide rail 436, and the cap indexing turntable 41 and the cap fixing seat 42 are respectively provided with a second guide slot 412 and a third guide slot 423 for the annular slide rail 436 to drive the transmission rod 434 to slide back and forth;

[0049] The annular slide rail 436 is coaxially arranged with the inner ring seat 435, and the annular slide rail 436 consists of a first slide rail section and a second slide rail section. The first slide rail section extends from the rear of the feeding mechanism 7 to the rear of the assembly mechanism 9, and the second slide rail section extends from the rear of the assembly mechanism 9 to the rear of the feeding mechanism 7. The diameter of the first slide rail section is larger than the diameter of the second slide rail section, and the first slide rail section and the second slide rail section are connected by a smooth transition.

[0050] Therefore, after the cap is transported 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 of the slide rail from the second section of the slide rail, and at the same time moves outward along the second guide groove 412 and the third guide groove 423. At this time, the transmission rod 434 slides synchronously along the first guide groove 433, prompting the first limiting arm 431 and the second limiting arm 432 to rotate inward around the pin axis, fixing the cap in the positioning groove, thereby ensuring that the cap is stably and accurately positioned during the rotation process, and completing the effective fixation of the cap;

[0051] After the cap is assembled, 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 slide rail from the first slide rail, and at this time moves inward along the second guide groove 412 and the third guide groove 423. At the same time, the transmission rod 434 slides synchronously under the guidance of the first guide groove 433, prompting the first limiting arm 431 and the second limiting arm 432 to rotate outward around the pin axis, 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 transport the cap to the inside of the positioning groove 422.

[0052] In order to ensure that the pressing force applied during the assembly process is uniform and consistent, and to effectively prevent the connection between the cap and the antenna sleeve from loosening, the cap fixing seat 42 is further provided with a lateral pressing device 44 on the positioning groove 422, and the lateral pressing device 44 includes an annular base 441, on which a plurality of splints 442 are evenly distributed in an annular manner, and an expansion joint is formed between two adjacent splints 442, and the splints 442 are surrounded by a truncated cone shape that is narrow at the top and wide at the bottom. The base 441 slides up and down along a slideway 424. The top of the cap fixing seat 42 is provided with a guide cylinder 425 that slides with the clamping plate 442. The guide cylinder 425 is in the shape of a hollow cone that is narrow at the top and wide at the bottom. A spring 443 is provided between the slideway 424 and the annular base 441 and is sleeved on the outside of the clamping plate 442. The side wall of the push rod 95 is provided with a protrusion 951 that pushes the annular base 441 to slide up and down within the slideway 424. The first and second sockets 411 and 421 are both formed with a through groove for the protrusion 951 to pass through.

[0053] Specifically, the lifting cylinder 94 drives the push rod 95 to pass through the first hole 411 and the second hole 421 and move upward, first lifting the cap to connect with the bottom of the antenna sleeve. During the upward movement of the push rod 95, when the protrusion 951 is close to the bottom of the annular base 441, the protrusion 951 pushes the annular base 441 to move upward along the slide 424, and then the annular base 441 squeezes the spring 443 and drives the clamping plate 442 to move upward synchronously. Since the guide cylinder 425 is a hollow frustum with a narrow upper part and a wide lower part, as the annular base 441 moves upward, the clamping plate 442 is gradually squeezed toward the middle, thereby forming a uniform surrounding pre-tightening force on the side wall of the cap, which not only effectively improves the initial bonding strength between the side of the cap and the antenna sleeve, but also enhances the stability of the connection between the cap and the antenna sleeve.

[0054] After the assembly is completed, the push rod 95 moves downward and resets. At this time, the spring 443 pushes the annular base 441 to move downward and reset along the slide 424, thereby separating the splint 442 from the cap and restoring and unfolding the splint 442.

[0055] Balls 426 are provided 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, so that when the cap is pushed upward from the positioning groove 422 and connected to the bottom of the antenna sleeve, the friction between the cap and the cap fixing seat 42 is reduced.

[0056] The glue injector 84 includes a glue injection tube 841 and a glue coating head 842 arranged at the bottom of the glue injection tube 841. The side walls and bottom of the glue coating head 842 are formed with a plurality of glue outlet holes. When the glue injection cylinder 83 pushes the glue injector 84 downward, the glue coating head 842 applies glue to the inner wall and bottom wall of the cap in a quantitative and uniform manner through the glue outlet holes, ensuring a firm and reliable connection between the cap and the antenna sleeve, significantly improving the stability and durability of the connection between the cap and the antenna sleeve, avoiding loosening or falling off caused by poor connection, and further improving the overall quality and service life of the antenna.

[0057] The clamping mechanism 96 includes a third bracket 961 fixed to the top of the frame 1, and the third bracket 961 is provided with a sliding cylinder 962 facing below the overlap 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. When in use, the sliding cylinder 962 pushes the clamping cylinder 963 forward, prompting the clamping claws of the clamping cylinder 963 to align with the antenna sleeve, and then the antenna sleeve is clamped and fixed by the clamping cylinder 963, ensuring that the antenna sleeve always remains firmly fixed during the assembly process to prevent loosening or position displacement from affecting the quality of subsequent operations or connections.

[0058] The feeding mechanism 7 includes a cap vibrating plate 71 on one side of the frame 1, a feeding guide rail 72 connected to the discharge port of the cap vibrating plate 71, the other end of the feeding guide rail 72 is aligned with the positioning groove 422 of the cap fixing seat 42, and 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. When in use, the cap is transported to the feeding guide rail 72 by the cap vibrating plate 71 and ensured to flow smoothly along the guide rail. When the cap reaches the end of the feeding guide rail 72, the pushing cylinder 73 is started to push the cap into the positioning groove 422 in the cap fixing seat 42, completing the automatic loading process of the cap.

[0059] The annular base 441 and the truncated cone formed by the clamping plate 442 have an opening slot for the cap to pass upward, so that when the push rod 95 pushes the cap upward, the cap can be easily connected to the bottom of the antenna sleeve through the opening slot.

[0060] 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, so that it is stably fixed in the groove and ensures that the cap is aligned in the center.

[0061] Anything not described in detail in the present invention is well known to those skilled in the art.

[0062] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
