The glue pad is installed inside the glue base shell, and the spiral rod is installed inside the gun barrel. The gun barrel and the glue base shell are then fixed together by clips. Previously, this was done manually, which was inefficient and labor-intensive. Therefore, the applicant designed an automated assembly equipment for long glue guns to automatically achieve the above-mentioned automatic assembly. Summary of the Invention

[0041] Reference Figures 1 to 3This invention discloses an automated assembly equipment for long glue guns, including a machine base 1, a bottom shell vibrating feeding plate 100, a spiral rod vibrating feeding mechanism 101, a gun barrel vibrating feeding plate 102, a gun barrel assembly divider 103 and a combined assembly divider 104 mounted on the machine base 1, a gun barrel bottom template 105 mounted on the gun barrel assembly divider 103, a bottom shell bottom template 106 mounted on the combined assembly divider 104, a gun barrel gripping mechanism 107, a spiral rod gripping mechanism 108, and a spiral rod stamping mechanism 109 arranged around the gun barrel assembly divider 103; a bottom shell gripping mechanism 110, a rubber pad cutting and fitting mechanism 111, a cylinder pressing and detection structure 112, and a glue gun finished product discharge gripping mechanism 113 arranged around the combined assembly divider 104, and a gun barrel transfer mechanism 114 arranged between the gun barrel assembly divider 103 and the combined assembly divider 104, wherein the gun barrel gripping mechanism 107 is capable of feeding the gun barrels from the vibrating feeding plate 102. The gun barrel 115 is gripped into the corresponding gun barrel bottom template 105. The spiral rod gripping mechanism 108 can grip the spiral rod 116 into the corresponding gun barrel. The spiral rod stamping mechanism 109 can completely press the spiral rod 116 into the gun barrel 115. After being stamped by the spiral rod stamping mechanism 109, the gun barrel 115 can be gripped onto the corresponding rubber bottom shell 117 by the gun barrel transfer mechanism 114. The bottom shell gripping mechanism 110 can move the bottom shell vibrating feeder. The adhesive base shell 117 within the 100mm diameter is gripped into the corresponding base shell template 106. The adhesive pad cutting mechanism 111 cuts the adhesive tape into adhesive pads and presses them into the corresponding adhesive base shell 117. The gun barrel 115, gripped by the gun barrel transfer mechanism 114, is pressed by the barrel pressing detection structure 112, causing the gun barrel 115 to snap together with the corresponding adhesive base shell 117 to form a finished product. The glue gun finished product discharge gripping mechanism 113 can grip the assembled finished product to a designated position.

[0042] The barrel base template 105 includes a slot 8 and a barrel bottom hole located on the bottom surface of the slot 8. The slot 8 is used to restrict the gun base of the barrel 115, and the barrel part of the barrel 115 passes through the barrel bottom hole. Of course, the turntable on the barrel assembly divider 103 is also provided with a clearance hole. In order to improve efficiency, two barrels 115 can be placed on the barrel base template 105 of this application. The bottom shell template 106 is provided with a positioning hole for placing the rubber bottom shell 117. Similarly, there are two positioning holes. Because there are many steps and processes in this application, two dividers are used: the barrel assembly divider 103 and the combined assembly divider 104.

[0043] Reference Figure 4The screw vibrating feeding mechanism 101 includes a screw vibrating plate 12, a first conveying trough 13, a second conveying trough 14, a vision detection mechanism 15, and a detection and gripping reversing mechanism. The vision detection mechanism 15 is located between the first conveying trough 13 and the second conveying trough 14. The first conveying trough 13 is connected to the screw vibrating plate 12. The detection and gripping reversing mechanism can grip the screw 116 from the first conveying trough 13 and, after detection by the vision detection mechanism 15, convey it into the second conveying trough 14. A vertical vibrator 16 is also installed at the bottom of the second conveying trough 14 to ensure that the screw 116 is delivered from the second conveying trough 14 to the desired trough. The desired trough is located on the desired block and is not affected by the vibration of the vertical vibrator 16. In the above structure, the vertical vibrator 1... 6. The screw vibrating plate 12 and the image detection mechanism 15 are existing structures, so they will not be described in detail. Their specific working principle is as follows: the screw vibrating plate 12 horizontally transports the screw 116 to the end of the first conveying trough 13. The detection gripping and reversing mechanism clamps the screw 116 at the end of the first conveying trough 13. During the clamping process, the screw 116 passes over the image detection mechanism 15. The camera of the image detection mechanism 15 will capture an image of the screw 116 for comparison to determine whether the orientation of the screw 116 is correct. If the orientation is incorrect, the screw 116 will be rotated 180 degrees during the process of the detection gripping and reversing mechanism clamping the screw 116 and moving it to the second conveying trough 14, so that the orientation of the screw 116 is correct. Because the orientation of the screw rod 116 in this application is random when it is conveyed to the conveying trough 13 by the screw rod vibrating plate 12, but our screw rod gripping mechanism 3 grips in a fixed position and rotates in a directional direction, it is necessary to unify the orientation of the screw rod 116 before the screw rod gripping mechanism 3 grips it, so as to ensure that it is installed correctly in the subsequent installation.

[0044] like Figure 8 and Figure 9The specific structure of the detection gripping reversing mechanism is as follows: the detection gripping reversing mechanism includes a gripping reversing seat 18, a gripping reversing motor 19 mounted on the gripping reversing seat 18, a reversing plate 20 connected to the gripping reversing motor 19, a reversing roller assembly 21 driven by the reversing plate 20, a reversing guide rail mechanism, a reversing mounting plate 23, and a reversing clamping cylinder 24 mounted on the reversing mounting plate 23. The reversing roller assembly 21 is connected to the reversing mounting plate 23, and the reversing mounting plate 23 is mounted on the gripping reversing seat 18 through the reversing guide rail mechanism. The working principle of the above structure is as follows: the rotation of the gripping reversing motor 19 drives the reversing plate 20 to rotate, and the reversing plate 20 drives the reversing roller assembly 21 to rotate simultaneously. 1. Rotation: The reversing roller assembly 21 drives the reversing mounting plate 23 to rotate, thereby enabling the reversing clamping cylinder 24 to clamp the screw rod 116 from the first conveying groove 13 into the second conveying groove 14 as the reversing mounting plate 23 rotates. However, during the above process, the reversing mounting plate 23 needs to remain vertical because the screw rod 116 needs to be horizontal and its orientation cannot be changed. Therefore, the reversing mounting plate 23 can remain vertical during the movement through the reversing roller assembly 21. The above structure moves smoothly and is accurately positioned. Moreover, the gripping reversing motor 19 adopts a servo motor, which can accurately control the position and speed during the movement, which is beneficial for cooperating with the camera in the vision system to improve detection accuracy.

[0045] The above structure uses a gripping reversing motor in conjunction with a reversing plate 20, a reversing roller assembly 21, a reversing guide rail mechanism, and a reversing mounting plate 23 to realize the lifting and translating motion of the reversing gripping cylinder 24. This not only saves costs but also allows for control of the movement speed, which is beneficial for achieving different purposes at different movement stages. During the gripping process, the vision detection mechanism 15 identifies the orientation of the spiral rod 116 held by the reversing gripping cylinder 24 and controls the reversing gripping cylinder 24 to change direction, thereby adjusting the orientation of the spiral rod 116. The above process is not only highly efficient but also simple in structure.

[0046] The specific structure is as follows: the reversing roller assembly 21 includes a reversing roller shaft 210, a reversing connecting plate 212 mounted on the reversing roller shaft 210, and several bearings 211. The reversing connecting plate 212 is fixed to the reversing roller shaft 210 by threads, and the bearings 211 are tightly fitted onto the reversing roller shaft 210. The gripping reversing seat 18 is provided with a U-shaped side guide groove 25, and the reversing plate 20 is provided with a reversing elongated hole 26. The end of the reversing roller shaft 210 passes through the reversing elongated hole 26. 6 is located in the side guide groove 25, and the reversing roller shaft 210 contacts the side guide groove 25 and the reversing elongated hole 26 through the corresponding bearing 211. Therefore, the reversing roller shaft 210 can rotate freely but can also be guided by the side guide groove 25 and the reversing elongated hole 26. The reversing connecting plate 212 is connected to the reversing mounting plate 23. Through the above structure, the reversing mounting plate 23 is eccentrically set relative to the reversing roller shaft 210. Therefore, when the reversing roller shaft 210 drives the reversing mounting plate 23... During the movement, the reversing mounting plate 23, because its center of gravity must remain constant, will drive the reversing roller shaft 210 to rotate, thereby keeping itself vertical and thus keeping the helical rod 116 horizontal. This structure adopts a U-shaped side guide groove 25, because the U-shaped side guide groove 25 includes a horizontal groove. When the reversing roller shaft 210 passes through the horizontal groove, it moves in a straight line, so the reversing mounting plate will not swing to adjust its angle, which is beneficial for the camera below to capture clearly. Moreover, because it is controlled by a servo motor, the speed of the reversing roller shaft 210 can be adjusted and slowed down when passing through the horizontal groove, which is also beneficial for the camera below to capture clearly. If the camera captures the helical rod facing in reverse, the control system will control the reversing clamping cylinder 24 to rotate 180 degrees, thereby reversing the direction of the helical rod. The reversing clamping cylinder 24 is an existing product that can realize the 180-degree rotation of both jaws together and the opening and closing of both jaws. The reversing plate 20 is provided with a reversing elongated hole 26, so that when the reversing plate drives the reversing roller shaft 210 to move, it will not get stuck because the trajectory is U-shaped.

[0047] As shown in the figure, the reversing guide rail mechanism includes a reversing transverse plate 27, a transverse guide rail assembly 221, and a lifting guide rail assembly 222. The transverse guide rail assembly 221 is mounted on the gripping reversing seat 18, the reversing transverse plate 27 is mounted on the transverse guide rail assembly 221, and the lifting guide rail assembly 222 is mounted on the reversing transverse plate 27. The reversing mounting plate 23 is connected to the lifting guide rail assembly 222. Through the guidance and support of the above structure, the smooth movement of the reversing mounting plate 23 in the plane is ensured. The transverse guide rail assembly 221 and the lifting guide rail assembly 222 are existing structures, so they will not be described in detail.

[0048] like Figure 5As shown, the barrel transfer mechanism 114 includes a barrel transfer base 28, a barrel transfer lateral movement mechanism 29 disposed on the barrel transfer base 28, a barrel transfer lateral movement plate 30 driven by the barrel transfer lateral movement mechanism 29, a barrel transfer lifting mechanism 31 disposed on the barrel transfer lateral movement plate 30, a barrel transfer lifting plate 32 driven by the barrel transfer lifting mechanism 31, a barrel transfer rotation mechanism 33 disposed on the barrel transfer lifting plate 32, a barrel transfer flipping plate 34 driven by the barrel transfer rotation mechanism 33, and a barrel gripper cylinder 35 disposed on the barrel transfer flipping plate 34. The barrel gripper cylinder 35 is provided with a barrel gripper capable of gripping the barrel 11. Through the above structure, the barrel gripper cylinder 35 can realize the movement of two points of gripping and placing in the plane, as well as the 180-degree flipping of the barrel gripper cylinder 35. Moreover, the structure is simple and the cost is low. Both the barrel transfer lateral movement mechanism 29 and the barrel transfer lifting mechanism 31 are cylinders, and the barrel transfer rotation mechanism 33 is a rotary cylinder. All of the above are existing technologies, so their specific connection structure and movement mode will not be described in detail. Of course, this structure also includes a barrel transfer guide rail assembly 36, which is connected to the barrel transfer lifting plate 32 to support and guide the barrel transfer lifting plate 32, ensuring that its movement is smooth and the force is even.

[0049] like Figure 6 As shown, the barrel gripping mechanism 107 includes a barrel gripping seat, on which a barrel gripping transverse cylinder and a barrel gripping transverse plate driven by the barrel gripping transverse cylinder are provided. The barrel gripping transverse plate is provided with a barrel gripping lifting cylinder and a barrel gripping lifting plate driven by the barrel gripping lifting cylinder. The barrel gripping lifting plate is provided with a barrel 11 gripping cylinder. The structural principle of the barrel gripping seat is the same as that of the translation part of the barrel transfer mechanism 114, both of which realize the movement of two points of gripping and placement in the plane through the driving of the cylinder.

[0050] like Figure 7 As shown, the spiral gripping mechanism 108 includes a spiral gripping seat, on which a spiral gripping transverse cylinder and a spiral gripping transverse plate driven by the spiral gripping transverse cylinder are mounted. The spiral gripping transverse plate is equipped with a spiral gripping lifting cylinder and a spiral gripping lifting plate driven by the spiral gripping lifting cylinder. The spiral gripping lifting plate is equipped with a spiral gripping rotation cylinder and a spiral gripping rotation plate driven by the spiral gripping rotation cylinder. The spiral gripping rotation plate is equipped with a spiral gripping cylinder. The structural principle of the spiral gripping mechanism 108 is the same as that of the barrel transfer mechanism 114; both achieve movement between two points of gripping and placement in a plane through the driving of cylinders, and achieve directional rotation of the spiral rod 116 through the driving of the spiral gripping rotation cylinder.

[0051] As shown in the figure, the spiral rod stamping mechanism 109 includes a spiral rod stamping seat and a spiral rod stamping cylinder disposed on the spiral rod stamping seat. The spiral rod stamping cylinder is provided with a spiral rod stamping head, which stamps the spiral rod 116 into the gun barrel 11.

[0052] As shown in the figure, the bottom shell gripping mechanism 110 and the barrel gripping mechanism 107 have the same principle and similar structure, so the specific structure will not be described in detail.

[0053] Bottom shell gripping mechanism 110, rubber pad cutting and loading mechanism 111, cylinder pressing and detection structure 112, glue gun finished product discharge gripping mechanism 113.

[0054] Reference Figure 10 and Figure 11 This invention discloses a rubber pad cutting and assembly mechanism 111 for an automated assembly equipment for long glue guns, including a punching mechanism and a rubber pad conveying mechanism for conveying the rubber pad to the punching mechanism. The punching mechanism includes a punching frame 37, a punching blade (not shown in the figure), and a punching blade 39. The punching frame 37 is provided with a punching drive unit 40 and a punching seat 41. The punching seat 41 is provided with a first punching die hole 38 that mates with the punching blade and a second punching die hole 42 that mates with the punching blade 39. The punching drive unit 40 is fixed to the punching blade and the punching blade 39 through a connecting plate 52. The bottom shell 1 is located below the second punching die hole 42, and the punching blade 39 can pass through the second punching die hole 42 to press the punched rubber pad into the bottom shell 1. During production, the rubber pad is located on the punching seat 41, and the punching drive unit 40 drives the punching blade. The punching blade 39 cuts out rubber pads from the tape and presses them into the bottom shell 1. Because the rubber pads in this application are four-petaled with a central hole, and the pads need to be pressed into the bottom shell 1 during punching, the pads need to be punched twice. During the first punching, the punching blade punches out the first hole in the tape. Of course, the punching blade 39 is cutting in the air. Then the punching blade and the punching blade 39 return to their original positions and rise. The tape conveyor pulls the tape a certain distance. At this time, the first hole is located below the punching blade 39. Then the punching blade and the punching blade 39 start the second punching simultaneously. The punching blade 39 punches out the rubber pad containing the first hole and presses it into the bottom shell 1, while the punching blade punches out the second hole in the tape. The process is repeated continuously to punch out several rubber pads and install them in the bottom shell 1. The punching seat 41 is provided with an insert 43, and the second punching die hole 42 is located in the insert 43. Because the insert 43 is made of a material with high hardness and wear resistance, the service life of the punching seat 41 is extended.

[0055] As shown in the figure, the tape conveying mechanism includes a tape conveying frame 45 for mounting the tape roll 44, a drive wheel 46 and a drive wheel 47 mounted on a punching frame 37. The drive wheel 46 is driven to rotate by a tape pulling drive unit 48, which is a servo motor. The drive wheel 46 and the drive wheel 47 are ordinary round rollers made of plastic. The drive wheel 46 is connected to the servo motor via a key. The drive wheel 47 contains a bearing. The punching frame 37 has a shaft that fits tightly with the bearing, thereby enabling the drive wheel 47 to rotate. The tape is located between the drive wheel 46 and the drive wheel 47 and is clamped by the drive wheel 46 and the drive wheel 47. The tape is moved by the drive wheel 46 to pull the tape out of the tape roll 44. As a preferred structure, a wheel clamping cylinder 49 is installed on the punching frame 37. The wheel clamping cylinder 49 is provided with a drive wheel seat. The second drive wheel 47 is rotatably connected to the drive wheel seat. The wheel clamping cylinder 49 drives the second drive wheel 47, thereby making the conveyor belt in close contact with the first drive wheel 46 and the second drive wheel 47, so that it can be driven.

[0056] As shown in the figure, it also includes a guide groove 50 fixed on the punching frame 37. The tape is held in the guide groove 50 and guided onto the punching seat 41 by the guide groove 50. The above structure can utilize space and avoid the problem of right-angle turns or twisting of the tape. As a further structure, the punching seat 41 is provided with an upper seat plate 51, and the upper seat plate 51 is provided with a guide groove 50. The tape passes through the guide groove 50, thus guiding the movement of the tape.

[0057] As shown in the figure, the connecting plate 52 is provided with a positioning rod 53. To ensure that the tape does not deviate during punching, the positioning rod 53 is positioned by cooperating with the round hole. As a further preferred structure, the bottom end face of the punching blade 39 is provided with a positioning post 54. The positioning post 54 is positioned by cooperating with the round hole on the punched tape, thereby preventing the tape from flying out. As a further optimized structure, the connecting plate 52 is provided with an air hole 55, and the punching blade 39 is provided with an air hole 2 (not shown in the figure). The air hole 55 and the air hole 2 are connected. The air hole 55 is connected to an external air extraction device through a pipe. The air extraction device can be a vacuum pump. When the vacuum pump is turned on, the punched tape is adsorbed onto the bottom end face of the punching blade 39 through the air hole 55 and the air hole 2, thereby preventing the tape from flying out or rotating when the punching blade 39 descends rapidly. To facilitate processing and manufacturing, the connecting plate 52 is provided with an upper connecting plate 57, and the air hole 55 is provided on the upper connecting plate 57.

[0058] like Figure 12 , Figure 17 , Figure 14As shown, this invention discloses a cylinder pressing and testing structure 112 for an automated assembly equipment for long glue guns, including a pressing mechanism and a pneumatic testing mechanism mounted on the machine base. The bottom of the positioning hole of the glue base shell 117 is provided with a cross groove, and the bottom of the cross groove is provided with a connector avoidance hole for the air supply connector 56 to extend out. Because the axial upward direction of the base shell is not fixed, when we use the pneumatic testing mechanism for testing, when the airtight nozzle 58 and the air connector 56 need to be clamped together, the top of the glue base shell 117 needs to be pressed by the pressing mechanism.

[0059] like Figure 13 and Figure 15 As shown, the air pressure detection mechanism includes an air pressure detection base 59, an air pressure lifting unit 60 disposed on the air pressure detection base 59, and an air pressure detection element 61. The air pressure detection element 61 is provided with an airflow hole 62 and an airtight nozzle 58 communicating with the airflow hole 62. The rubber base shell 117 can be pressed into the positioning hole by a pressing mechanism. The air pressure detection element 61 can be lifted by the air pressure lifting unit 60, thereby sealing the airtight nozzle 58 with the air connector 56 on the base shell. The airflow hole 62 is connected to a vacuum generator through a pipeline. The air pressure lifting unit... The 60 uses a cylinder, the air pressure detection component 61 is an iron plate, the airflow hole 62 is set on the side of the iron plate, and the airtight nozzle 58 is set on the top surface of the iron plate. Through the above structure, we realize the connection and disconnection of the airtight nozzle 58 and the air connector 56. When the cylinder drives the air pressure detection component 61 to rise, the airtight nozzle 58 can be fitted onto the air connector 56. When the cylinder drives the air pressure detection component 61 to fall, the airtight nozzle 58 can be disconnected from the air connector 56. This makes it convenient for the bottom template to be transferred to the next process with the bottom shell after testing. For airtightness, the airtight nozzle 58 is equipped with a sealing ring.

[0060] The clamping mechanism includes a clamping frame 63, a clamping cylinder 64 mounted on the clamping frame 63, a guide rail assembly 65, and a clamping block 66. The clamping cylinder 64 is connected to the clamping block 66, and the clamping block 66 is connected to the guide rail assembly 65. The clamping block 66 is lifted and lowered by the cylinder to clamp the glue base shell 117. As a preferred structure of this application, the bottom surface of the clamping block 66 is provided with a pressing hole 67 that matches the shape of the end of the gun barrel 115. The bottom of the pressing hole 67 is provided with a through hole. Because the bottom end of the cylinder 115 of the spiral glue gun needs to be inserted into the glue base shell 117 and then snapped together by a buckle, the cylinder 115 needs a stamping process after being inserted into the glue base shell 117 to snap together with the glue base shell 117. In order to make full use of machine space and reduce processes, we will... The stamping process of the barrel 115 and the inspection process of the gasket are designed to be completed in one process. Therefore, the pressure block 66 can restrict and fix the rubber base shell 117 simply by stamping the barrel 115. However, since the end of the barrel 115 is a relatively thin cone, the pressure block 66 is provided with a pressure hole 67 in order not to damage the barrel 115. This increases the extrusion surface, disperses the extrusion force, and thus enables the stamping of the barrel 115. Moreover, the air in the pressure hole 67 can be discharged more quickly through the through hole, which facilitates the stamping. As a further structure, the machine base is provided with an auxiliary clamping cylinder and a clamping block connected to the auxiliary clamping cylinder. The clamping block has a semi-circular clamping groove. Because the barrel 115 is relatively thin and long, during stamping, the auxiliary clamping cylinder drives the clamping block to rotate and close to hold the barrel 115, preventing the barrel 115 from swaying or bending and deforming during stamping.

[0061] like Figure 16 As shown, because the stamping pressure is high, the machine is equipped with an auxiliary support mechanism, including a support cylinder 68 and a support block 69. The support cylinder 68 and the support block 69 are located under the turntable, and the support block 69 can support the turntable. Moreover, the support block 69 is provided with several rubber blocks 70, which are in contact with the turntable, so that the rubber blocks 70 can buffer the impact force.
