Detailed Implementation
[0017] 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.
[0018] 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.
[0019] like Figures 1 to 9 As shown, a thermostat manufacturing and assembly equipment of the present invention includes: a fixed plate 1, on which a through hole 2, a through hole 3 and a through hole 4 are formed, the through hole 2 and the through hole 3 are both vertical, and the through hole 3 is horizontal. The movable plate 5 moves along through hole 1 2, through hole 2 3 and through hole 3 4. The movable plate 5 is elastically connected to the base plate 6. More specifically, one end of the optical axis 7 is fixed on both sides of the movable plate 5. The other end of the optical axis 7 passes through the base plate 6 and a baffle 8 is fixed on this end. A spring 1 9 is mounted on the optical axis 7. Under the action of the elastic force of the spring 1 9 and the gravity of the movable plate 5, the baffle 8 contacts the movable plate 5. The movable plate 5 and the base plate 6 are also included. The movable plate 5 is equipped with a clamping assembly; The fixing plate 1 is equipped with two limiters, which are used to limit the base plate 6; In this embodiment, two limiters are installed at the pick-up and put-down positions, respectively, such as... Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the movable plate 5 is in the middle position of the through hole 2. At this time, the limiter presses against the substrate 6, preventing the substrate 6 from continuing to descend, so that the movable plate 5 continues to move downward along the through hole 2. The optical axis 7, the movable plate 5, etc. all move downward relative to the substrate 6. The spring 9 is compressed, which reduces the distance between the movable plate 5 and the substrate 6, triggering the clamping component to perform a clamping action to clamp the product. Then, the movable plate 5 and the others move upward along the through hole 2, causing the product to leave the mold at this position. During this process, the self-locking component is locked, so that the distance between the movable plate 5 and the substrate 6 remains small. Subsequently, the moving plate 5 moves horizontally along through hole 2 3, moving the product directly above the mold at the placement position. Then, the moving plate 5 moves vertically downward along through hole 3 4. After the base plate 6 contacts the limiter at this location, the moving plate 5 continues to descend to the limit position and then rises, causing the self-locking component to unlock. Under the elastic force of spring 1 9, the distance between the moving plate 5 and the base plate 6 increases to [missing value]. Figure 1 As shown in the figure, the product is released. Similarly, the product transfer can be completed by restoring the moving plate 5 to its initial state and repeating the above process.
[0020] The present invention may be further improved, such as Figure 1 , Figure 8 and Figure 9 As shown, the self-locking assembly includes a first groove 10 and a second groove 11 formed on the movable plate 5. One end of the first groove 10 is connected to one end of the second groove 11, and both the first groove 10 and the second groove 11 have corners. The other end of the first groove 10 is connected to one end of the third groove 12. The other end of the third groove 12 is connected to one end of the fourth groove 13. The other end of the fourth groove 13 is connected to the other end of the second groove 11. The first groove 10, the second groove 11, the third groove 12 and the fourth groove 13 roughly form a rhombus. Furthermore, the depths of the first groove 10, the second groove 11, the third groove 12, and the fourth groove 13 are different; more specifically, for example... Figure 8 and Figure 9 As shown, the depth of the third groove 12 is greater than the depth of the first groove 10. The depth of the fourth groove 13 near the end of the third groove 12 is greater than that of the third groove 12. The depth of the fourth groove 13 near the end of the second groove 11 gradually decreases, and a discontinuity is formed at the connection between the fourth groove 13 and the second groove 11. Figure 8 and Figure 9 The shaded area represents the formation of a fault. The depth of the other end of the second groove 11 gradually increases until it remains constant, and the depth of one end of the second groove 11 is less than the depth of the first groove 10. like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the self-locking assembly also includes one end of a rocker arm 14 rotatably mounted on the movable plate 5. The rocker arm 14 rotates around the pivot 15. The other end of the rocker arm 14 is elastically connected to a guide shaft 16. More specifically, a hollow shaft 17 is fixed to the other end of the rocker arm 14. The guide shaft 16 is slidably connected to the hollow shaft 17. A second spring 18 is fitted on the guide shaft 16. The two ends of the second spring 18 are in close contact with the inner wall of the hollow shaft 17 and the support ring 19 on the guide shaft 16, respectively. Under the elastic force of the second spring 18, the end of the guide shaft 16 is always in close contact with the inner wall of the four grooves. The guide shaft 16 moves along the first groove 10, the second groove 11, the third groove 12 and the fourth groove 13. In this embodiment, as Figure 1 and Figure 3 As shown, the guide shaft 16 is at one end of the first groove 10. When the limiter at the position abuts against the substrate 6, the moving plate 5 and the like continue to descend, causing the guide shaft 16 and the like to move upward relative to the moving plate 5. Since the depth of one end of the second groove 11 is less than the depth of the first groove 10, and the rocker arm 14 and the guide shaft 16 can rotate around the pivot 15, the downward movement of the moving plate 5 relative to the substrate 6 will cause the guide shaft 16 to move along the first groove 10. When the moving plate 5 moves to the limit position, the guide shaft 16 has moved to the third groove 12. Since the third groove 12 is deeper than the first groove 10, the guide shaft 16 will not return to the first groove 10. Subsequently, the movable plate 5 moves upward along the through hole 2. Since the movable plate 5 is elastically connected to the substrate 6, the movable plate 5 will move upward a certain distance first. During this process, the guide shaft 16 moves from the third groove 12 to the fourth groove 13. At this time, the guide shaft 16 will be stuck in the fourth groove 13, thereby locking the distance between the movable plate 5 and the substrate 6. Then the movable plate 5, which continues to move upward, will move upward along with the substrate 6, etc. When the substrate 6 moves to contact the limiter at the placement position, the substrate 6 cannot move down. The moving plate 5 continues to move downward, causing the guide shaft 16 to move along the fourth groove 13 to the second groove 11. When the moving plate 5 reaches the limit position, the guide shaft 16 reaches the other end of the second groove 11. Then the moving plate 5 moves upward, and the guide shaft 16 moves along the second groove 11 to the initial position of the first groove 10. At this time, the baffle 8 contacts the substrate 6, and the distance between the moving plate 5 and the substrate 6 reaches its maximum.
[0021] The present invention may be further improved, such as Figure 3 and Figure 6 As shown, a drive shaft 20 is fixed on the movable plate 5; The clamping assembly includes a shaft tube 21 rotatably mounted on the base plate 6, with a spiral hole 22 formed on the shaft tube 21, through which the drive shaft 20 passes; The shaft tube 21 is fixed with a drive disk 23, and two drive holes are opened on the drive disk 23 that are not coaxial with the drive disk 23. The base plate 6 is fixed with a bracket 24. The bracket 24 has two sliders 25 that slide on it. The sliders 25 slide at the elongated holes opened on the bracket 24. A connecting shaft 26 that passes through the drive hole is fixed on the sliders 25. Sliding slider 25 is slidably mounted with clamp 27; In this embodiment, when the moving plate 5 moves up and down, it also moves the drive shaft 20 up and down, such as... Figure 3 As shown, when the moving plate 5 and the drive shaft 20 move downward, the drive shaft 20 moves downward relative to the shaft tube 21. Since the drive shaft 20 passes through the spiral hole 22, it will cause the shaft tube 21 and the drive disk 23 to rotate. Since the drive hole is not coaxial with the drive disk 23, the slider 25 and the clamping plate 27 move closer to each other and clamp the product. Similarly, when the moving plate 5 moves upward relative to the base plate 6, the clamping plate 27 releases the product.
[0022] The present invention may be further improved, such as Figure 2 and Figure 7 As shown, the slider 25 is threadedly connected to the lead screw 28, one end of the lead screw 28 is rotatably connected to the clamping plate 27, and two limiting shafts 29 are fixed on the clamping plate 27 and slidably connected to the slider 25. The other end of the lead screw 28 is fixed with a spline shaft 30, and a spline sleeve 31 slides on the spline shaft 30. The bracket 24 is rotatably mounted with a horizontal shaft 32 by two stabilizing plates. In order to prevent the horizontal shaft 32 from contacting the slider 25, the slider 25 has a hole for the horizontal shaft 32 to pass through. The horizontal shaft 32 is connected to the two spline sleeves 31 through a transmission. The spline sleeves 31 are also rotatably connected to the stabilizing plates. The horizontal shaft 32 and the spline sleeves 31 are connected through a transmission via a sprocket and a chain 33. In this embodiment, when the drive disk 23 rotates, it drives the two sliders 25 and the clamping plate 27 to move in opposite directions. During this process, relative sliding occurs between the spline shaft 30 and the spline sleeve 31. Since the stroke of the drive shaft 20 is fixed and the angle of the spiral hole 22 is fixed, the stroke of the clamping plate 27 is constant. Therefore, by adjusting the initial position of the clamping plate 27, more sizes of products can be accommodated. When it is necessary to adjust the initial position of the clamping plate 27, rotate the horizontal shaft 32 to drive the spline sleeve 31, spline shaft 30 and lead screw 28 to rotate, so that the two clamping plates 27 move in opposite directions at the same time.
[0023] The present invention may be further improved, such as Figure 3 As shown, one end of the spiral hole 22 is connected to a through hole 34, which is set along the axis of the shaft tube 21. In this embodiment, as Figure 3 As shown, the bottom end of the through hole 34 is connected to the bottom end of the spiral hole 22. When the drive shaft 20 moves along the through hole 34, it will not cause the shaft tube 21 to rotate. After the clamping assembly performs the clamping action, the moving plate 5 will move up slightly before driving the substrate 6 to move up. During this process, the drive shaft 20 moves along the through hole 34 and will not cause the shaft tube 21 to rotate, so the product will not be released.
[0024] The present invention may be further improved, such as Figure 1 , Figure 3 and Figure 6 As shown, a movable block 35 slides on the fixed plate 1, a movable block 36 slides on the movable block 35, a movable shaft 37 is fixed on the movable block 36, and the movable shaft 37 is connected to the movable plate 5. More specifically, the movable block 35 slides on the track 38 connected to the fixed plate 1, and the movable block 36 slides on the track 39 connected to the movable block 35.
[0025] The present invention may be further improved, such as Figure 4 As shown, a main shaft is rotatably mounted on the fixed plate 1. The main shaft is driven to rotate by the motor 40. A drive rod 41 is fixed on the main shaft. The drive rod 41 is slidably connected to the moving shaft 37. More specifically, an elongated hole is opened on the drive rod 41, and the moving shaft 37 passes through the elongated hole on the drive rod 41. In this embodiment, the motor 40 is turned on to rotate the drive rod 41. Since the moving shaft 37 passes through the elongated hole on the drive rod 41, the drive rod 41 generates a thrust on the moving shaft 37, causing the moving shaft 37 and the moving plate 5 to move along through hole 2, through hole 3 and through hole 4. During this process, the relative position of the moving shaft 37 and the drive rod 41 changes. In summary, the moving plate 5 can be controlled to move along through hole 2, through hole 3 and through hole 4 by the motor 40. During the above process, the second movable block 36 slides relative to the first track 38 and the second track 39, and the first movable block 35 slides relative to the first track 38. Since the second movable block 36 does not rotate, and the movable shaft 37 is connected to the second movable block 36, the movable shaft 37 and the movable plate 5, etc., will not rotate.
[0026] The present invention may be further improved, such as Figure 3 and Figure 4 As shown, the limiter includes a connecting bracket 42 connected to the fixed plate 1, and a bolt 43 is threaded onto the connecting bracket 42; In this embodiment, the relative position of the bolt 43 and the connecting bracket 42 can be adjusted, thereby making it easier to adjust the stopping position of the substrate 6.
[0027] The present invention may be further improved, such as Figure 4 As shown, buffers 44 are slidably installed on both sides of the fixed plate 1; In this embodiment, the position of the buffer 44 relative to the fixed plate 1 can be adjusted. When the drive rod 41 contacts the swing arm, the buffer 44 controls the motor 40 to stop and reverse, that is, the moving plate 5 reaches the limit position.
[0028] In a further improvement to the present invention, a key is installed between the moving shaft 37 and the moving block 36; In this embodiment, a key is installed between the movable shaft 37 and the movable block 36 to prevent relative rotation between the movable block 36 and the movable shaft 37.
[0029] When using this invention, first adjust the position of the limiter and the buffer 44, then operate the motor 40 to rotate the drive rod 41, so that the moving plate 5 moves along the through hole 1 2, through hole 2 3 and through hole 3 4; like Figure 4 As shown, at this time, the guide shaft 16 is on one end of the first groove 10. When the limiter at the position abuts against the substrate 6, the moving plate 5 and the like continue to descend, which will cause the guide shaft 16 and the like to move upward relative to the moving plate 5. Since the depth of one end of the second groove 11 is less than the depth of the first groove 10, and the swing rod 14 and the guide shaft 16 can rotate around the pivot 15, the downward movement of the moving plate 5 relative to the substrate 6 will cause the guide shaft 16 to move along the first groove 10. When the moving plate 5 moves to the limit position, the guide shaft 16 has moved to the third groove 12. Since the third groove 12 is deeper than the first groove 10, the guide shaft 16 will not return to the first groove 10. In the above process, the drive shaft 20 moves downward with the moving plate 5. The drive shaft 20 passes through the spiral hole 22 and the through hole 34 in succession, so that the clamping plate 27 clamps the product. Subsequently, the movable plate 5 moves upward along the through hole 2. Since the movable plate 5 is elastically connected to the substrate 6, the movable plate 5 will move upward a certain distance first. During this process, the guide shaft 16 moves from the third groove 12 to the fourth groove 13. At this time, the guide shaft 16 will be stuck in the fourth groove 13, thereby locking the distance between the movable plate 5 and the substrate 6. During this process, the drive shaft 20 moves along the through hole 34 and will not cause the shaft tube 21 to rotate. Then the movable plate 5, which continues to move upward, will carry the substrate 6 and others upward. When the substrate 6 moves to contact the limiter at the placement position, the substrate 6 cannot move down. The moving plate 5 continues to move downward, causing the guide shaft 16 to move along the fourth groove 13 to the second groove 11. During this process, the drive shaft 20 moves along the through hole 34. When the moving plate 5 reaches the limit position, the guide shaft 16 reaches the other end of the second groove 11. Then the moving plate 5 moves upward, and the guide shaft 16 moves along the second groove 11 to the initial position of the first groove 10. At this time, the baffle 8 contacts the substrate 6, and the distance between the moving plate 5 and the substrate 6 reaches its maximum. During the above process, the drive shaft 20 moves along the spiral hole 22, causing the clamping plate 27 to release the product.
[0030] 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.
