Description

Technical Field

[0001] The present invention relates to the field related to the production of walkie-talkie antennas, and in particular to an automatic assembly mechanism for an antenna cap. Background Art

[0002] Walkie-talkies are two-way mobile communication tools that allow calls without any network support and without incurring phone charges. They are suitable for relatively fixed and frequent call situations. They are composed of a casing, a host, a battery, a belt clip, a charger, and an antenna. The antenna is an important component of the walkie-talkie. It is mainly responsible for transmitting the radio frequency signal generated by the internal circuit of the walkie-talkie so that the signal can propagate in the air to achieve long-distance communication. At the same time, it also undertakes the task of receiving radio frequency signals from the outside world and transmits the received weak signals to the receiving circuit of the walkie-talkie for subsequent processing. It is a "bridge" to ensure normal communication of the walkie-talkie. In order to provide protection for the antenna, it is usually necessary to assemble a cap on the antenna, thereby providing waterproof and dustproof protection for the antenna through the cap, and also reducing the damage to the top of the antenna by external forces such as collision, friction, and scratches.

[0003] The existing antenna end cap assembly method is usually manual operation, which makes the antenna cap assembly efficiency low. For example, patent number CN220575878U discloses an operating table for walkie-talkie antenna assembly, which only provides a workbench. The antenna assembly process has a low degree of automation, which easily affects the assembly efficiency.

[0004] For example, the patent number is: CN205195025U, which discloses an assembly mechanism for an antenna connector, which places the antenna in the wire clamping group and places the connector in the clamping module group formed by the left clamping module and the right clamping module. Then the third cylinder works to tighten the wire clamping group to clamp the antenna. At the same time, the second cylinder works to close the right clamping module to the left clamping module to tighten the connector. Then the fourth cylinder works to move the third bracket through the longitudinal guide rail group to punch the antenna into the connector, completing the first step; then the third cylinder works to open the wire clamping group, and then the first cylinder works to move the stamping positioner forward to punch the connector toward the antenna, thereby completing the stamping. Subsequently, the second cylinder works to retract the right clamping die, while the fourth cylinder and the first cylinder retract the third bracket and the stamping limiter respectively, thus completing the assembly of the antenna connector. However, it has fewer workstations, and it is necessary to take out an antenna after assembly and then put in another antenna for assembly, which is prone to work gaps. In addition, the degree of automation of the loading and unloading process is low, which easily affects the assembly efficiency, and it is not convenient to automatically discharge the assembled antennas in a sorted manner, which brings inconvenience to the subsequent storage and organization of the antennas.

DETAILED DESCRIPTION

[0039] In order to further explain the technical solution of the present invention, specific embodiments are described in detail below.

[0040] like Figure 1 As shown, the present invention provides an automatic assembly mechanism for antenna caps, comprising a workbench 1, an antenna conveyor tray 2 and a cap conveyor tray 3 disposed on the workbench 1, a first support frame 7 and a second support frame 11 fixedly mounted on the top of the workbench 1, two driving members 6 being mounted on the workbench 1, the output shafts of the two driving members 6 being connected to the middle portions of the bottom end surfaces of the antenna conveyor tray 2 and the cap conveyor tray 3, respectively;

[0041] The drive member 6 in this embodiment uses a stepper motor. By controlling the frequency and number of pulses, the rotation angle and speed of the output shaft of the drive member 6 can be precisely controlled, so that the antenna conveyor plate 2 and the cap conveyor plate 3 can be accurately intermittently rotated, so that the antenna and the cap can be accurately aligned.

[0042] like Figures 1 to 12 As shown, in this embodiment, a plurality of antenna positioning frames 4 are installed at the edge of the antenna conveyor tray 2 and are distributed in an annular shape with equal spacing. A plurality of cap positioning frames 5 are locked and fixed at the edge of the cap conveyor tray 3 and are distributed in an annular shape with equal spacing. The cap positioning frames 5 are provided with grooves for providing positioning for the caps, and a feeding mechanism 10 for conveying the caps is provided outside the cap conveyor tray 3.

[0043] The first support frame 7 is provided with a pressing component 8 and a glue dispensing component 9. The pressing component 8 is used to squeeze the lower end of the antenna into the cap, and the glue dispensing component 9 is used to introduce glue into the cap.

[0044] The second support frame 11 is provided with a material taking mechanism 12 for clamping the assembled antenna, and a guide mechanism 13 is provided below the material taking mechanism 12 for guiding and discharging the assembled antenna;

[0045] The guide mechanism 13 includes a U-shaped discharge frame 131 locked and fixed to the side surface of the second support frame 11, the U-shaped discharge frame 131 extends obliquely downward from right to left, and the left end of the U-shaped discharge frame 131 is connected in parallel with the fixed frame 132 installed on the side surface of the workbench 1, and a guide frame 133 corresponding to and parallel to the U-shaped discharge frame 131 is slidably installed in the fixed frame 132. The guide frame 133 is used to receive the antenna sliding out of the U-shaped discharge frame 131, and the guide frame 133 can move back and forth along the fixed frame 132, so as to transport the antenna to different positions in the collection frame. The front end surface of the fixed frame 132 is locked and fixed with a motor 134, which is a servo motor. The motor 134 is connected to a screw 135 rotatably installed in the fixed frame 132 through a coupling, and the screw 135 is threadedly connected to the bottom of the guide frame 133;

[0046] Several Hall effect sensors 1311 are installed at the bottom of the fixed frame 132, and an induction magnet 1312 that cooperates with the Hall effect sensors 1311 is fixedly embedded at the bottom of the guide frame 133;

[0047] An opening 136 is formed at the left end of the bottom of the guide frame 133, and a fixing bracket 138 is fixedly mounted on the bottom end surface of the guide frame 133. A limit crank 137 for limiting the position of the antenna is rotatably mounted in the opening 136. An opening and closing cylinder 139 is rotatably mounted in the fixing bracket 138. The piston rod on the left side of the opening and closing cylinder 139 is rotatably connected to the limit crank 137.

[0048] The Hall effect sensors 1311 in the fixed frame 132 are evenly spaced. Different Hall effect sensors 1311 cooperate with the induction magnets 1312 to detect the specific position of the guide frame, thereby facilitating precise control of the antenna ejection position.

[0049] In this embodiment, a second detection sensor 1310 for detecting an antenna is embedded in the side surface of the guide frame 133. The second detection sensor 1310 is located to the right of the limit crank 137. In this embodiment, the second detection sensor 1310 is a reflective photoelectric sensor. When an antenna appears in the guide frame 133, the intensity of the reflected light in the detection area changes. The sensor determines whether the antenna exists based on the change in the intensity of the received reflected light.

[0050] In this embodiment, a rubber sheet 1313 is attached to the top surface of the limit crank 137 to provide a buffer for the antenna and reduce the impact force between the antenna and the limit crank 137;

[0051] like Figure 4 and Figure 5 As shown, in this embodiment, the antenna positioning frame 4 includes a plurality of hollow seats 41 mounted on the antenna conveyor plate 2, and a positioning cylinder 42 slidably mounted in the hollow seat 41. The positioning cylinder 42 is through-through and is used to provide positioning for the antenna. A first protrusion 43 is provided on the top of the outer side of the positioning cylinder 42. The inner side of the positioning cylinder 42 is a tapered shape that tapers from top to bottom. A second protrusion 44 is mounted on the inner bottom of the hollow seat 41. The top surface of the second protrusion 44 is connected to the bottom of the first protrusion 43 via a spring 45.

[0052] Specifically, when in use, the electrical equipment in this assembly machine is connected to an external programmable controller, and each electrical equipment is programmed and controlled by the programmable controller. The antenna of the walkie-talkie to be assembled is inserted upside down into the positioning tube 42, so that the smaller end of the antenna passes through the positioning tube 42. When the thicker end of the antenna moves downward and contacts the inner side of the positioning tube 42, the antenna stops moving downward. At this time, the antenna is located inside the positioning tube 42.

[0053] like Figure 7 As shown, in this embodiment, the pressing assembly 8 includes a pressing cylinder 81 installed on the top of the left end surface of the first support frame 7, a connecting seat 82 installed on the piston rod at the bottom of the pressing cylinder 81, and a pressing plate 83 for pressing the antenna is installed at the bottom of the connecting seat 82. The pressing plate 83 is located directly above the rightmost antenna conveyor plate 2, and at this time, the rightmost antenna conveyor plate 2 is located directly above the rearmost cap positioning frame 5;

[0054] In this embodiment, a pressure sensor 84 is provided between the connecting seat 82 and the pressing plate 83. The pressure sensor 84 detects the pressure exerted by the pressing plate 83 on the antenna to better control the extension and contraction of the piston rod of the pressing cylinder 81, thereby preventing the antenna from being damaged by excessive pressure.

[0055] like Figure 7 As shown, in this embodiment, the dispensing assembly 9 includes an adjustment seat 91 mounted on the front end surface of the first support frame 7, an adjustment cylinder 92 locked and fixed to the top of the adjustment seat 91, a sliding seat 93 slidably mounted on the adjustment seat 91 and connected to the piston rod at the bottom of the adjustment cylinder 92, and a dispensing head 94 is fixed on the sliding seat 93. The dispensing head 94 is located above the cap positioning frame 5 at the right end;

[0056] like Figure 8As shown, in this embodiment, the feeding mechanism 10 includes a vibration plate 101 provided at the right end of the top of the workbench 1, a feeding track 102 for conveying caps connected to the output end of the vibration plate 101, and the left end of the feeding track 102 is connected to the inner side of the transfer rack 103 installed on the top surface of the workbench 1;

[0057] The front end of the transfer rack 103 is provided with a pushing cylinder 104 connected to the top surface of the workbench 1, and a pushing block 105 connected to the piston rod at the rear end of the pushing cylinder 104 is slidably installed in the transfer rack 103. A first detection sensor 106 for detecting caps is installed on the top of the transfer rack 103. The pushing block 105 is facing the cap positioning frame 5 at the front end. The pushing block 105 is used to squeeze the caps in the transfer rack 103 into the cap positioning frame 5 at the front end;

[0058] The first detection sensor 106 in this embodiment is a reflective photoelectric sensor, which determines that the cap has entered the transfer rack 103 by detecting the change in the intensity of the reflected light in the transfer rack 103;

[0059] Specifically, when in use, the antenna cap is pre-placed into the vibration disk 101, and the cap is transported to the feeding track 102 through the vibration disk 101. The cap is introduced into the transfer rack 103 through the feeding track 102. When the first detection sensor 106 detects that the cap has entered, the pushing cylinder 104 pushes the pushing block 105 to move backward and pushes the cap into the cap positioning rack 5 at the front end, and the driving member 6 at the bottom of the cap conveying disk 3 drives the cap conveying disk 3 to rotate, and the cap conveying disk 3 drives the cap positioning rack 5 and the cap to rotate to the bottom of the dispensing head 94, and the sliding seat 93 and the dispensing head 94 are driven downward by the adjusting cylinder 92, and the dispensing head 94 moves downward into the cap, and the dispensing head 94 is used to dispense glue to the inside of the cap. After the dispensing is completed, the adjusting cylinder 92 drives the dispensing head 94 to move upward and reset;

[0060] At the same time, the driving part 6 at the bottom of the antenna conveying disk 2 is started to drive the antenna positioning frame 4 and the walkie-talkie antenna to rotate at the same time. When the antenna positioning frame 4 drives the antenna to rotate to the rightmost end, the cap with glue on the cap conveying disk 3 rotates to the leftmost end. At this time, the antenna is aligned with the cap, and the pressing cylinder 81 drives the connecting seat 82 and the pressing plate 83 to move downward. The pressing plate 83 squeezes the antenna so that the lower end of the antenna is pressed into the cap. Under the action of the glue in the cap, the lower end of the antenna is bonded and fixed to the inner side of the cap, and the antenna drives the positioning cylinder 42 to move downward during the downward movement. The spring 45 is elastically compressed by the pressure of the first protrusion 43 on the positioning cylinder 42. When the antenna and the cap are assembled, the pressing cylinder 81 drives the pressing plate 83 to move upward and reset. The positioning cylinder 42 and the antenna move upward under the elastic force of the spring 45, and the antenna carries the cap in the cap positioning frame 5 to move upward, and the cap is separated from the inner side of the cap positioning frame 5, completing the automatic assembly of the antenna and the cap.

[0061] like Figure 9 As shown, in this embodiment, the material taking mechanism 12 includes a conveying cylinder 121 fixedly mounted on the top of the front end surface of the second support frame 11, a first sliding frame 122 slidably mounted on the second support frame 11 and connected to the piston rod of the conveying cylinder 121, and the first sliding frame 122 can move left and right along the second support frame 11;

[0062] A lifting cylinder 123 is fixedly secured to the top of the first sliding frame 122. A second sliding frame 124 connected to the piston rod at the bottom of the lifting cylinder 123 is slidably mounted on the first sliding frame 122. The second sliding frame 124 can move vertically along the first sliding frame 122. A clamping cylinder 125 for clamping the assembled antenna is mounted on the second sliding frame 124. The clamping cylinder 125 is acted upon by the conveying cylinder 121 to deliver the clamped antenna into the U-shaped discharge frame 131.

[0063] Specifically, when the antenna and the cap are assembled, the driving part 6 continues to drive the antenna conveyor plate 2 to rotate, and the antenna conveyor plate 2 rotates the assembled antenna to the top left end of the workbench 1, and the lifting cylinder 123 drives the second sliding frame 124 and the clamping cylinder 125 to move downward, and the clamping cylinder 125 moves downward to clamp the upper end of the antenna. When the lifting cylinder 123 moves upward, it drives the clamping cylinder 125 and the antenna to move upward, and the antenna moves upward and leaves the inner side of the positioning cylinder 42, and then the conveying cylinder 121 drives the first sliding frame 122, the lifting cylinder 123, the second sliding frame 124, the clamping cylinder 125 and the antenna to move to the left. At this time, the antenna moves left to the inner top of the U-shaped discharge frame 131, and the lifting cylinder 123 drives the clamping cylinder 125 to move downward. The cylinder 125 and the antenna move downward, the antenna enters the U-shaped discharge frame 131, and the clamping cylinder 125 is controlled to lower the antenna. The antenna is limited by the front and rear sides of the U-shaped discharge frame 131, and because the U-shaped discharge frame 131 is tilted, the antenna tilts and slides downward along the U-shaped discharge frame 131 into the guide frame 133. The antenna stops moving downward after sliding in contact with the limit crank 137 in the guide frame 133. At this time, the second detection sensor 1310 detects the antenna and drives the limit crank 137 to rotate downward and retract into the opening 136 by controlling the opening and closing cylinder 139. Since the guide frame 133 is tilted and parallel to the U-shaped discharge frame 131, the antenna continues to slide downward to the external antenna collection frame.

[0064] During the antenna discharge process, the next antenna can be placed in the positioning cylinder 42 and assembled with the cap in the next cap positioning frame 5. When the next assembled antenna enters the guide frame 133, the motor 134 is started and drives the screw 135 to rotate. The screw 135 drives the guide frame 133 threaded therewith to move horizontally forward. The guide frame 133 drives the induction magnet 1312 to move. When the positioning frame 133 drives the induction magnet 1312 to move the position of the second Hall effect sensor 1311, the second Hall effect sensor 1311 installed here senses the change in the magnetic field and immediately sends a signal to the controller indicating that the plate has reached the first preset position. At this time, the opening and closing cylinder 139 is controlled to open the limit crank 137 to discharge the second antenna from the position of the second Hall effect sensor 1311. Then the motor 134 is controlled to reverse and drive the guide frame 133 to move backward and reset to the position of the first Hall effect sensor 1311. When the third antenna enters the guide frame 133, the output shaft of the motor 134 rotates forward and cooperates with the screw 135 to drive the guide frame 133 to move forward to the third Hall effect sensor 1311, and the opening and closing cylinder 139 is controlled to discharge the third antenna from the third Hall effect sensor 1311. After the third antenna is discharged, the motor 134 reverses and drives the guide frame 133 to move backward and reset. At the same time, the opening and closing cylinder 139 drives the limit crank 137 to rotate and reset to provide a limit for the fourth antenna. Similarly, the assembled antennas are transported to different positions in the collection frame in sequence, reducing the accumulation of antennas at one position in the collection frame, and facilitating the collection and arrangement of antennas.

[0065] The present invention provides an automatic assembly mechanism for antenna caps, which simultaneously conveys multiple caps by arranging multiple cap positioning frames 5 on a cap conveying tray 3, and introduces glue into the caps through a glue dispensing component 9. Multiple antenna positioning frames 4 on the antenna conveying tray 2 can simultaneously convey multiple antennas, and then the antennas are pressed into the caps through a pressing component 8 to complete the antenna assembly work, and the assembled antennas are taken out through a material taking mechanism 12. Since multiple antenna positioning frames 4 and multiple cap positioning frames 5 are provided, when one group of antennas and caps are being taken out, another group of antennas and caps can be assembled synchronously, and the assembly process is more continuous, which is conducive to improving work efficiency.
