DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 are within the scope of protection of the present invention.

[0031] like Figure 1 , Figure 2 As shown, this embodiment discloses a nailing device, including a fixing plate 1 and a conveying platform 4. The conveying platform 4 is located below the fixing plate 1, and the fixing plate 1 is kept in a fixed position. Figure 1 The conveying platform 4 moves in the direction of the arrow. A limit seat 41 is installed on the upper end of the conveying platform 4. The limit seat 41 can hold the lamp body 5. The lamp body 5 is inserted into the limit seat 41. The inner wall of the limit seat 41 limits the lamp body 5 in the horizontal direction. A lamp cover 51 is installed on the upper end of the lamp body 5. The bottom of the lamp cover 51 is inserted into the lamp body 5 so that the lamp body 5 limits the lamp cover 51 in the horizontal direction. The lamp cover 51 is provided with a hole 511. The lamp cover 51 is fixedly connected to the lamp body 5 by screws 7.

[0032] The nailing device also includes a support ring 16, the bottom surface of the support ring 16 abuts against the upper end surface of the fixing plate 1, and the support ring 16 is provided with a through hole 162 and a groove body 163. The through hole 162 axially penetrates the support ring 16. The through hole 162 is a tapered hole with a large diameter at the upper end and a small diameter at the lower end. The maximum diameter of the through hole 162 is larger than the maximum outer diameter of the screw 7, and the minimum diameter of the through hole 162 is the same as the minimum outer diameter of the screw 7. A through groove is provided at the bottom of the fixing plate 1, and the through groove is located below the support ring 16. The through hole 162 is connected to the through groove at the bottom of the fixing plate 1. Figure 4 , Figure 7 The screw 7 includes a rod portion 71 with a smaller diameter, and the rod portion 71 passes through the through hole 162 and the through slot of the fixing plate 1.

[0033] like Figure 3 , Figure 4 As shown, the groove body 163 radially penetrates the outer wall of one side of the support ring 16 , and the through hole 162 is connected to the groove body 163 .

[0034] like Figure 4As shown, the support ring 16 includes two spliced ​​ring bodies 161, and the two ring bodies 161 can be radially close to or away from each other to break the through hole 162, so that the screw 7 can completely pass through the through hole 162 downward. Specifically, the fixing plate 1 is installed with a fixing block 13, and the inner wall of the fixing block 13 is slidably connected with a slide rod 14, and the slide rod 14 is fixedly connected with the ring body 161. The slide rod 14 includes a rod head 141, and the outer wall of the slide rod 14 is sleeved with a spring 15. The rod head 141 and the spring 15 are respectively located on both sides of the fixing block 13. The diameter of the rod head 141 is larger than the inner hole of the fixing block 13 through which the slide rod 14 passes. One end of the spring 15 abuts the fixing block 13, and the other end of the spring 15 abuts the ring body 161. Under the action of the spring 15, the top of the screw 7 can be hung on the inner wall of the through hole 162. When a force is applied downward to the screw 7, the screw 7 pushes the ring body 161 away, so that the screw 7 can completely pass through the through hole 162 downward.

[0035] like Figure 1 As shown, two material platforms 2 are installed on the upper end surface of the fixed plate 1, and a gap 3 is formed between the two material platforms 2. The upper end surface of the material platform 2 is an inclined surface, and the upper end surface of the material platform 2 gradually tilts downward along the direction close to the support ring 16. A screw 7 is hung on the upper end surface of the material platform 2, and the screw 7 can slide along the upper end surface of the material platform 2. The rod 71 penetrates the gap 3. The through groove of the fixed plate 1 is correspondingly arranged above and below the gap 3 to prevent the fixed plate 1 from interfering with the rod 71. The material platform 2 includes a buffer table 21, and the upper end surface of the buffer table 21 is a horizontal surface. Figure 2 The groove body 163 docks with the gap 3, so that the screw 7 sliding down along the upper end surface of the material table 2 can pass through the groove body 163 and enter the through hole 162.

[0036] like Figure 2 As shown, the fixed plate 1 is installed with a driving component 11, and the driving component 11 is a cylinder. A moving block 111 is installed at the output end of the driving component 11, and the moving block 111 is located above the support ring 16. The groove 163 is located at one end of one of the diameter lines of the support ring 16, and the moving block 111 is located at the other end of the diameter line. The moving block 111 can move along the diameter line under the drive of the driving component 11, and the diameter line is toward the length direction of the gap 3. The moving block 111 is installed with a magnetic component 1111, so that when the moving block 111 is close to the screw 7, it can magnetically attract the screw 7 and pull the screw 7 into the through hole 162.

[0037] like Figure 2 As shown, the buffer table 21 is installed with a driving component 12 and a baffle 17. The driving component 12 is a cylinder. A moving block 121 is installed at the output end of the driving component 12. The moving block 121 can move along the width direction of the gap 3 under the drive of the driving component 12. The moving block 121 and the baffle 17 are respectively located on both sides of the length direction of the gap 3. The moving block 121 and the baffle 17 can clamp the top of the screw 7 to limit the screw 7.

[0038] Combination Figure 5 , Figure 6 , support rods 1211 are provided on both sides of the moving block 121, one of the support rods 1211 is hinged with a roller 12111, the roller 12111 can rotate along its own axis, the roller 12111 can abut against the screw 7, and the roller 12111 is located on the side of the moving block 121 away from the support ring 16. When the moving block 121 approaches the screw 7, the roller 12111 first contacts the screw 7, and since the roller 12111 rotates after contacting the screw 7, the screw 7 also tends to rotate, which has a force unloading effect, and the roller 12111 pushes the screw 7 to continue to move forward in the transmission direction, so that the screw 7 is not easy to jump and lose its position due to the excessive thrust of the moving block 121.

[0039] like Figure 7 As shown, the fixing plate 1 is also equipped with a connection seat 8, and the connection seat 8 is located below the material platform 2. The connection seat 8 is equipped with a second magnetic component 81, which is a magnet. The second magnetic component 81 is in the shape of a long strip. The length direction of the second magnetic component 81 is arranged parallel to the material platform 2. The second magnetic component 81 is located below the rod 71, so that when the screw 7 is hung on the upper end surface of the material platform 2 and moves obliquely downward, due to the force of the second magnetic component 81, the axis of the screw 7 can remain perpendicular to the upper end surface of the material platform 2, thereby preventing the screw 7 from flipping or tilting when moving, causing transmission blockage. At the same time, the inclination of the upper end surface of the material platform 2 and the horizontal plane is set at 30°-45°, and the minimum distance between the second magnetic component 81 and the rod 71 is set at 10CM-14CM, so that the attraction of the second magnetic component 81 to the rod 71 is controlled at 0.1 times the weight of the screw 7-0.13 times the weight of the screw 7, so that the screw 7 can still move obliquely upward under the attraction of the second magnetic component 81 to achieve transportation.

[0040] like Figure 4 As shown, the fixing plate 1 is also installed with a fixing seat 18, and the fixing seat 18 is installed with a sensor 19. The inner wall of the fixing seat 18 is slidably connected to the limit rod 6. The limit rod 6 is axially arranged perpendicular to the lamp cover 51. The limit rod 6 axially passes through the fixing seat 18. The limit rod 6 includes a boss 61 located at the top, and the diameter of the boss 61 is larger than the hole through which the limit rod 6 passes through the fixing seat 18. When the boss 61 is located at the upper limit position, the sensor 19 can sense the boss 61 and be triggered. The limit rod 6 is installed with a ring 63, and the ring 63 is located below the fixing seat 18. The outer wall of the limit rod 6 is sleeved with a spring 2 62, and one end of the spring 2 62 abuts against the ring 63, and the other end of the spring 2 62 abuts against the fixing seat 18. The bottom of the limit rod 6 can be inserted into the channel 511, and after insertion, the limit rod 6 is located at the lower limit position, and the sensor 19 does not sense the boss 61 at this time. As shown Figure 7As shown, the fixing plate 1 is also installed with a second sensor 9, which can sense the lamp body 5 being transported into the fixing plate 1. When the second sensor 9 senses the state of the lamp body 5, the first sensor 19 is activated.

[0041] The nailing process of the nailing device includes the following steps:

[0042] ① Insert the screw 7 into the gap 3, the top of the screw 7 is hung on the upper end surface of the material platform 2 and is transmitted downward along the inclined surface of the material platform 2 under the action of gravity, the rod 71 is magnetically attracted by the magnetic component 81 so that when the screw 7 is transmitted downward along the upper end surface of the material platform 2, the axial direction of the screw 7 always remains perpendicular to the upper end surface of the material platform 2, thereby preventing the screw 7 from flipping or tilting when moving, causing transmission blockage.

[0043] ② When the screw 7 moves to the end (i.e., the point closest to the support ring 16), it is clamped and limited by the moving block 2 121 and the baffle 17. When the moving block 2 121 is close to the screw 7, the roller 12111 is first in contact with the screw 7. Since the roller 12111 rotates after contacting the screw 7, the screw 7 also tends to rotate, which has a force unloading effect, and the roller 12111 pushes the screw 7 to continue to move forward in the transmission direction, so that the screw 7 is not easy to jump and lose its position due to excessive thrust from the moving block 2 121.

[0044] ③ The moving block 2 121 loosens the screw 7, the output end of the driving component 11 extends out, and the magnetic component 1111 magnetically attracts the screw 7 loosened by the moving block 2 121 and pulls it into the supporting ring 16.

[0045] ④ The lamp body 5 enters the fixed plate 1 under the conveying of the conveying platform 4, and the sensor 2 9 senses the lamp body 5 and triggers a signal. When the sensor 2 9 senses the lamp body 5, the sensor 1 19 is enabled. When the bottom of the limit rod 6 is inserted into the first hole 511, the conveying platform 4 continues to convey. When the bottom of the limit rod 6 is inserted into the second hole 511, the conveying of the conveying platform 4 stops, and the screw 7 is driven into the lamp body 5 with a pneumatic screwdriver to fix the lamp body 5 and the lamp cover 51. When the screw 7 is driven into the lamp body 5, the screw 7 pushes the ring bodies 161 on both sides, and the screw 7 passes through the support ring 16 and the fixed plate 1.

[0046] When the bottom of the limiting rod 6 is inserted into the last hole 511 (the hole 511 is a process hole and is only used for the limiting rod 6 to be inserted and positioned), the assembly of the last screw 7 on the single lamp body 5 is completed.

[0047] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
