[0032] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] like Figures 2 to 9 As shown, a precision component welding and installation device for a video intercom device according to the present invention includes: a feeding assembly 1 for individually conveying a sensor body, a feeding assembly 2 for individually conveying a ball bearing, and a moving assembly 3 for moving the sensor body.

[0035] Feeding component 2 is installed at the discharge end of feeding component 1, and moving component 3 is installed below feeding component 1 and feeding component 2.

[0036] In this embodiment, during use, feeding component 1 feeds the sensor body, feeding component 2 feeds the ball bearings, and moving component 3 picks up a sensor body and moves it to feeding component 2. Feeding component 2 installs the ball bearings in the reserved position of the sensor body and performs welding. After welding is completed, moving component 3 moves the sensor body to other positions.

[0037] The present invention may be further improved, such as Figure 2 and Figure 5 As shown, the feeding assembly 1 includes two fixed rods 4, each with an inclined portion and a horizontal portion. A vibration motor 5 is installed on the inclined portion. The annular groove of the sensor body is fitted onto the two fixed rods 4, with a certain distance between them, allowing the two fixed rods 4 to pass through the annular groove of the sensor body. In use, the sensor body is manually placed between the two fixed rods 4, and the vibration motor 5 is started. Under the action of gravity, the sensor body is vertically arranged on the two fixed rods 4 and slides along the inclined and horizontal portions.

[0038] like Figure 7 As shown, the end of the horizontal part away from the inclined part is the discharge end. One of the fixed rods 4 at the discharge end has a sliding stop rod 6 and a stop rod 7. The stop rod 6 and the stop rod 7 are a certain distance apart, so that a sensor body can be accommodated between the stop rod 6 and the stop rod 7.

[0039] Furthermore, the first stop bar 6 and the second stop bar 7 are staggered, the height of the second stop bar 7 is the same as the height of the annular groove, the first stop bar 6 is located in the upper half of the sensor body, the sliding trajectory of the first stop bar 6 and the second stop bar 7 is perpendicular to the fixed rod 4, and also includes a drive assembly 1 for driving the first stop bar 6 and the second stop bar 7 to slide in the opposite direction;

[0040] The present invention may be further improved, such as Figure 7 and Figure 9 As shown, the drive assembly includes a drive motor 8 fixed on one of the fixed rods 4. The output shaft of the drive motor 8 is fixedly connected to the middle of the drive rod 9. One end of the drive rod 9 is slidably connected to the stop rod 6, and the other end of the drive rod 9 is slidably connected to the stop rod 7. More specifically, both the stop rod 6 and the stop rod 7 are L-shaped and have rectangular holes. Both ends of the drive rod 9 are fixed with pins 10 passing through the rectangular holes.

[0041] In this embodiment, as Figure 7 In the state shown, the first stop bar 6 blocks the first sensor body, and the second stop bar 7 does not overlap with the sensor body. The first drive motor 8 is operated to rotate the drive rod 9 by a certain angle. When the first stop bar 6 is separated from the first sensor body, the second stop bar 7 passes between the first sensor body and the second sensor body. The second stop bar 7 blocks the second sensor body to prevent it from moving due to vibration motor 5. Then the first sensor body is moved away by the moving component 3.

[0042] Then, reverse the operation of drive motor 8 to rotate drive lever 9 in the opposite direction by a certain angle, and stop levers 6 and 7 return to their original positions. Figure 7 As shown, under the action of the vibration motor 5, the second sensor body gradually contacts the stop bar 6, returning to the state shown. Figure 9 In the state shown.

[0043] The present invention may be further improved, such as Figure 5 As shown, the feeding assembly 2 includes a pipe 11 for placing balls, the pipe 11 including a vertical section 1 and a vertical section 2 and an inclined section connecting the two.

[0044] The vertical section 1 has through holes 12 and 13. The vertical section 1 is fixed with a base 14. The base 14 has a slider 15 that slides on it. The slider 15 is fixed with an intercepting rod 16 and an intercepting rod 27. There is a height difference between the intercepting rod 16 and the intercepting rod 27, and the height difference is approximately equal to the outer diameter of the ball. The end of the intercepting rod 27 is a bevel.

[0045] It also includes a second drive assembly, which is used to drive the first interceptor 16 and the second interceptor 17 to slide in the same direction at the first through hole 12 and the second through hole 13, respectively.

[0046] In this embodiment, as Figure 5 As shown, the balls are placed side by side inside the vertical section 1. At this time, the second interceptor rod 17 blocks the balls to prevent them from moving down. When a ball needs to be transported, the second drive assembly is operated to make the slider 15, the first interceptor rod 16, and the second interceptor rod 17 slide relative to the base 14. The first interceptor rod 16 extends into the inside of the pipe 11, while the second interceptor rod 17 gradually detaches from the pipe 11. Under the action of gravity, all the balls fall down and are intercepted by the first interceptor rod 16. Then, the second drive assembly is operated to make the slider 15, the first interceptor rod 16, and the second interceptor rod 17 slide in the opposite direction relative to the base 14. The second interceptor rod 17 intercepts the second ball, and the first interceptor rod 16 gradually detaches from the pipe 11. The first ball falls under the action of gravity and finally detaches from the pipe 11 along the vertical section 2 and falls to the reserved position of the sensor body.

[0047] The present invention may be further improved, such as Figures 3 to 4 As shown, the feeding assembly 2 also includes two fixing plates 18 and a fixing shaft 19 fixed on both sides of the pipe 11. The fixing plates 18 have through holes 3 20 and 4 21 that are connected. Through hole 3 20 is a horizontal hole and through hole 4 21 is a vertical hole. The fixing shaft 19 passes through through hole 3 20.

[0048] The main shaft 22 is rotatably mounted on the fixed plate 18. The main shaft 22 is located in the right-angle area formed by the through hole 3 20 and the through hole 4 21. One end of the main shaft 22 is fixed with the drive motor 23. The main shaft 22 is fixed with the rotating arm 24. The rotating arm 24 has a through hole 5. The fixed shaft 19 passes through the through hole 5.

[0049] The present invention may be further improved, such as Figures 3 to 4As shown, the second feeding assembly 2 also includes a guide rail 25 fixed on the fixed plate 18, a moving block 26 sliding on the guide rail 25, a guide rail 27 fixed on the moving block 26, a moving block 28 sliding on the guide rail 27, and a fixed shaft 19 passing through the moving block 28 and fixedly connected to the moving block 28.

[0050] In this embodiment, the second drive motor 23 is operated to rotate the main shaft 22 and the rotating arm 24. Since the fixed shaft 19 passes through the fifth through hole, and the fifth through hole is elongated, and since the main shaft 22 is located in the right-angle area formed by the third through hole 20 and the fourth through hole 21, the rotating arm 24 always exerts a thrust on the fixed shaft 19, causing the fixed shaft 19 to move along the third through hole 20 and the fourth through hole 21. During this process, the fixed shaft 19 drives the second moving block 28 to slide relative to the first guide rail 25 and the second guide rail 27. Since the second moving block 28 does not rotate, the fixed shaft 19, the pipe 11, etc. will not rotate. When the fixed shaft 19 and the pipe 11 pass through the third through hole 20, they move in the horizontal direction, and when they pass through the fourth through hole 21, they move in the vertical direction.

[0051] To prevent the connecting wires of the pipe 11 from touching the sensor body, the pipe 11 is positioned to the side of the sensor body when not in operation. After the moving component 3 moves the sensor body to the same vertical plane as the pipe 11, the second drive motor 23 is operated to rotate the main shaft 22 and the rotating arm 24. The pipe 11 first moves horizontally towards the sensor body, so that the second vertical section is aligned with the installation position of the ball. Then the pipe 11 moves vertically downward to reduce the distance between the output end of the pipe 11 and the sensor body, preventing the ball from rolling to other positions when it falls out. When the pipe 11 reaches the bottom, the second drive component is operated to slide the slider 15, the first interceptor 16, and the second interceptor 17 relative to the base 14, causing the ball to fall to the reserved position of the sensor body.

[0052] The present invention may be further improved, such as Figures 3 to 5 As shown, two fixed shafts 19 are fixedly connected to a hydraulic cylinder 29, and a welding head 30 is fixed at the output end of the hydraulic cylinder 29. A through hole 6 is opened at the vertical section 2 of the pipe 11 for the welding head 30 to enter and exit.

[0053] In this embodiment, after the ball falls to the reserved position on the sensor body, the hydraulic cylinder 29 is operated to move the welding head 30 downward, and the welding head 30 welds the sensor body and the ball together.

[0054] The present invention may be further improved, such as Figure 8As shown, the second drive assembly includes a third drive motor 31 fixed to one of the fixed plates 18. The output shaft of the third drive motor 31 is rotatably mounted with one end of a first connecting arm 32, and the other end of the connecting arm is rotatably mounted with a transition shaft 33. The transition shaft 33 is rotatably mounted with one end of a second connecting arm 34, and the other end of the second connecting arm 34 is rotatably mounted with a drive shaft 35. The transition shaft 33 and the output shaft of the third drive motor, as well as the transition shaft 33 and the drive shaft 35, are all connected by a chain 36.

[0055] One end of the extension rod 37 is fixed to the drive shaft 35, and the other end of the extension rod 37 is fixed to the power shaft 38. The slider 15 is fixed to the long strip plate 39, and the long strip plate 39 has a through hole 7 through which the power shaft 38 passes.

[0056] In this embodiment, as Figure 8 As shown, when the fixed shaft 19 moves along the through hole 3 20 and through hole 4 21, the connecting arm 1 32 and connecting arm 2 34 rotate adaptively, but the distance between the transition shaft 33 and the output shaft of the drive motor 31 and the distance between the transition shaft 33 and the drive shaft 35 remain unchanged, and the chain 36 connecting the three can always be used normally.

[0057] When it is necessary to move the slider 15, the drive motor 31 is turned on to make the drive shaft 35 and the extension rod 37 rotate. With the cooperation of the power shaft 38 and the long plate 39, the slider 15 and the others move.

[0058] The purpose of the above settings is to fix the position of the drive motor 31, reduce its vibration during operation, and lower the failure rate.

[0059] The present invention may be further improved, such as Figure 2 and Figure 5 As shown, the moving component 3 includes a slide table 40, the output end of the slide table 40 is a moving plate 41, the moving plate 41 is fixed with a drive motor 42, the output shaft of the drive motor 42 is fixed with a clamp 43, the clamp 43 is two clamping plates that are opened and closed by a cylinder, which will not be described in detail.

[0060] A camera assembly is installed above the discharge end;

[0061] In this embodiment, after the clamp 43 holds the first sensor body, the camera assembly takes a picture of the first sensor body and identifies the angle of the reserved position of the ball on the sensor body. Then, the data is transmitted to the drive motor 42. The output shaft of the drive motor 42 rotates to rotate the clamp 43 and the sensor body to a suitable angle. Then, the slide 40 is operated to move and stop the moving plate 41, etc.

[0062] The present invention may be further improved, such as Figure 2As shown, it also includes a conveying assembly 44 for conveying the sensor body after the ball bearings are assembled. The conveying assembly 44 includes two symmetrically arranged brackets, and the brackets are flared at the end near the feeding assembly 2.

[0063] In this embodiment, the sensor body after the ball bearings are welded is sent to the support by the slide table 40, the support passes through the annular groove of the sensor body, and then the clamp 43 is operated to release the sensor body.

[0064] When using this invention, the sensor body is manually placed between two fixed rods 4, and the vibration motor 5 is started. Under the action of gravity, the sensor body is vertically arranged on the two fixed rods 4 and slides along the inclined and horizontal parts.

[0065] like Figure 9 As shown, the first stop bar 6 blocks the first sensor body, and the second stop bar 7 does not overlap with the sensor body. The first drive motor 8 is operated to rotate the drive rod 9 by a certain angle. When the first stop bar 6 is separated from the first sensor body, the second stop bar 7 passes between the first sensor body and the second sensor body. The second stop bar 7 blocks the second sensor body to prevent it from moving due to the vibration motor 5. Then the first sensor body is moved away by the moving component 3.

[0066] The operating fixture 43 clamps the first sensor body, the camera assembly takes a picture of the first sensor body and identifies the angle of the reserved position of the ball on the sensor body, and then transmits the data to the drive motor 42. The output shaft of the drive motor 42 rotates to rotate the fixture 43 and the sensor body to a suitable angle. The operating slide 40 moves the sensor body to the feeding assembly 2. At this time, the pipe 11 is on the front side of the sensor body.

[0067] Then, drive motor 23 is operated to rotate the main shaft 22 and the rotating arm 24. Pipe 11 first moves horizontally towards the sensor body, aligning the vertical section 2 with the ball bearing installation position. Then, pipe 11 moves vertically downwards, reducing the distance between the output end of pipe 11 and the sensor body to prevent the ball bearing from rolling to other positions when it falls out. When pipe 11 reaches its bottom, drive motor 31 is activated to rotate the drive shaft 35 and the extension rod 37. With the cooperation of the power shaft 38 and the long strip plate 39, the slider 15, interceptor rod 16, and interceptor rod 17, etc., are rotated. The movement occurs as follows: the first interceptor rod 16 extends into the inside of the pipe 11, while the second interceptor rod 17 gradually detaches from the pipe 11. Under the action of gravity, all the balls fall and are intercepted by the first interceptor rod 16. Then, the third drive motor 31 is operated to make the slider 15, the first interceptor rod 16 and the second interceptor rod 17 slide in the opposite direction relative to the base 14. The second interceptor rod 17 intercepts the second ball, the first interceptor rod 16 gradually detaches from the pipe 11, the first ball falls under the action of gravity, and finally detaches from the pipe 11 along the vertical section 2 and falls to the reserved position of the sensor body.

[0068] After the ball falls to the reserved position on the sensor body, the hydraulic cylinder 29 is operated to move the welding head 30 down, and the welding head 30 welds the sensor body and the ball together.

[0069] After welding, drive motor 23 is operated to restore components such as pipe 11 to their initial positions, and then slide table 40 is operated to send the sensor body to the support of conveying assembly 44.

[0070] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
