[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Reference Figure 1-6 As shown, a high-speed precision transmission line includes:

[0029] A transmission frame 1 is provided with a conveyor line, and multiple positioning fixtures 2 are evenly arranged on the conveyor line;

[0030] A guiding mechanism is provided on the transmission frame 1. The guiding mechanism includes two guiding components 3, which are respectively provided on both sides of the transmission frame 1. The two guiding components 3 are used to guide and position the positioning fixture 2 on the transmission line.

[0031] A drive mechanism is mounted on the transmission frame 1. The drive mechanism includes a drive shaft 54 ​​and a power component 5. A drive frame 53 is mounted on the transmission frame 1. The drive shaft 54 ​​is rotatably mounted on the drive frame 53. The power component 5 is drivenly connected to the drive shaft 54. A guide drive component 4 is mounted on the bottom surface of the positioning fixture 2. A spiral guide groove 55 matching the guide drive component 4 is mounted on the drive shaft 54. The power component 5 is used to drive the drive shaft 54 ​​to rotate, thereby driving the guide drive component 4 on the positioning fixture 2 to move along the spiral guide groove 55 to realize the pushing and conveying of material to the positioning fixture 2.

[0032] The positioning fixture 2 of this utility model is provided with a guide drive component 4 on its bottom surface. The power component 5 drives the drive shaft 54 ​​to rotate, thereby driving the guide drive component 4 on the positioning fixture 2 to move along the spiral guide groove 55 to realize the pushing and conveying of the positioning fixture 2. Multiple positioning fixtures 2 are evenly arranged on the conveyor line and move synchronously under the traction of the positioning fixture 2, thereby forming a high-speed drive and positioning integrated positioning module design for the transmission of the positioning fixture 2, eliminating the need for secondary positioning and shortening the equipment operation time.

[0033] This invention transforms the rotational driving force of the drive shaft 54 ​​into the linear motion of the positioning fixture 2, forming a structure similar to a lead screw and nut transmission. This allows the positioning fixture 2 to move to the processing or inspection position without secondary positioning. The drive cam 42 and the spiral guide groove 55 cooperate to form the effect of a lead screw and nut. However, unlike a lead screw and nut, the drive cam 42 of this application moves in and out along the openings on both sides of the spiral guide groove 55. Driven by the conveyor belt 16, it does not require secondary alignment and can achieve positioning and transmission under the action of traction force.

[0034] In one embodiment of the present invention, the conveyor line includes two conveyor shafts 14, which are respectively disposed on both sides of the transmission frame 1. Synchronous pulleys 15 are disposed on both sides of the conveyor shafts 14. The synchronous pulleys 15 on the two conveyor shafts 14 are connected by a transmission belt 16. The positioning fixture 2 is connected to the transmission belt 16 by a fixing member.

[0035] Specifically, since the positioning fixture 2 is connected to the conveyor belt 16 through a fixing member, multiple positioning fixtures 2 on the conveyor belt 16 move synchronously under the traction of one positioning fixture 2, thereby forming a transmission of the positioning fixture 2.

[0036] In one embodiment of this utility model, the conveyor belt 16 is a chain or belt, which can install multiple positioning fixtures 2 while ensuring the consistency of transmission and the transmission accuracy of each positioning fixture 2.

[0037] In one embodiment of the present invention, the power component 5 includes a power frame 51, a power motor 52 is mounted on the power frame 51, a first gear 56 is mounted on the output shaft of the power motor 52, and a second gear 57 is mounted on the drive shaft 54, wherein the first gear 56 meshes with the second gear 57.

[0038] Specifically, the power component is a drive device for rotating the drive shaft. It can use existing transmission structures such as direct drive motors or synchronous belts to drive the drive shaft and ensure the rotational force of the drive shaft. It can be replaced according to different usage scenarios to achieve the function of driving the drive shaft to rotate.

[0039] In one embodiment of this utility model, the positioning fixture 2 includes a fixture plate 21, on which at least one positioning station is provided. The positioning station is provided with a positioning groove 22, and the positioning groove 22 is provided with a positioning block 23. The positions of the two guide components 3 can serve as the loading and unloading areas of the product 24. The product 24 can be quickly positioned by the positioning groove 22 and the positioning block 23 to ensure the accuracy of subsequent inspection or processing.

[0040] In one embodiment of the present invention, a support frame 11 is further included. The support frame 11 is disposed below the transmission frame 1. Mounting seats are provided on both sides of the support frame 11. Guide plates 12 are provided on the mounting seats. Guide slopes 13 are provided at both ends of the guide plates 12. The guide plates 12 are used to support the positioning fixture 2 located below the transmission frame 1.

[0041] Specifically, the support frame 11 is located below the transmission frame 1. When the positioning fixture 2 moves to the bottom of the transmission frame 1, the transmission belt 16 will be pulled down due to the weight of the positioning fixture 2. The guide plate 12 supports the positioning fixture 2 located below the transmission frame 1, guides the positioning fixture 2, reduces the downward force on the transmission belt 16, improves the life of the transmission belt 16, and ensures the positioning accuracy of the drive shaft 54 ​​on the positioning fixture 2.

[0042] In one embodiment of this utility model, the guide assembly 3 includes a fixed frame 31 and a movable frame 32. The fixed frame 31 is disposed on the transmission frame 1, and the movable frame 32 is disposed on the fixed frame 31. The movable frame 32 and the fixed frame 31 are provided with roller sets 33 for guiding and transmitting the upper and lower sides of the positioning fixture 2. The movable frame 32 is provided with a slot, and the slot is provided with guide rollers 34. The guide rollers 34 and the roller sets 33 form a conveying channel 35 for transmitting the positioning fixture 2.

[0043] Specifically, the movable frame 32 and the fixed frame 31 are provided with roller groups 33 for guiding and transmitting the upper and lower sides of the positioning fixture 2. The guide rollers 34 and the roller groups 33 form a conveying channel 35 for transmitting the positioning fixture 2, which further improves the conveying accuracy of the positioning fixture 2 during the transmission process. It can correct the position of one or more positioning fixtures 2, and under the drive of the conveyor belt 16, all positioning fixtures 2 can be conveyed in a consistent manner.

[0044] In one embodiment of this utility model, a guide rod 37 is provided on the fixed frame 31, and a guide blind hole 38 is passed through the guide rod 37 on the movable frame 32. A spring 39 is sleeved on the guide rod 37, and a limit block 36 is provided at the free end of the guide rod 37. One end of the spring 39 abuts against the limit block 36, and the other end abuts against the bottom surface of the guide blind hole 38.

[0045] Specifically, a spring 39 is fitted on the guide rod 37, and a limit block 36 is provided at the free end of the guide rod 37. Under the reaction force of the spring 39, the roller assembly 33 on the moving frame 32 presses and positions the positioning fixture 2 on the roller assembly 33 of the fixed frame 31. This can press and position the positioning fixture 2 in the vertical direction, ensuring the loading and unloading accuracy of the subsequent product 24 on the positioning fixture 2 and improving the processing quality.

[0046] In one embodiment of the present invention, the guide drive component 4 includes a guide frame 41, on which two drive rods are provided, and drive cams 42 are rotated on the drive rods. The spiral guide groove 55 forms a plurality of interconnected spiral grooves 43 on the drive shaft 54, and the two drive cams 42 are disposed in two adjacent spiral grooves 43.

[0047] Specifically, the two drive cams 42 on the drive frame 53 are set in two adjacent spiral grooves 43, and the drive cams 42 abut against the inner wall of the spiral grooves 43. The distance between the two drive cams 42 is the same as the multiple of the pitch of the spiral guide groove 55 (two or more adjacent spiral grooves 43). The rotational driving force of the drive shaft 54 ​​is converted into the linear motion of the positioning fixture 2, forming a structure similar to the transmission of a lead screw and nut. This drives the positioning fixture 2 connected to the drive cams 42 to move, realizing the feeding and conveying of the positioning fixture 2, and realizing the integrated positioning of high-speed drive and positioning.

[0048] In one embodiment of the present invention, the diameter of the drive cam 42 is the same as the width of the spiral groove 43, so that the drive cam 42 abuts against the inner wall of the spiral groove 43.

[0049] Specifically, the diameter of the drive cam 42 is the same as or slightly smaller than the width of the spiral groove 43, which can ensure the motion accuracy of the drive cam 42 and effectively avoid idle rotation during transmission due to excessive gap. While providing transmission power to the positioning fixture 2, it ensures the transmission position of the positioning fixture 2, eliminating the need for secondary positioning, shortening processing time, reducing production costs, and providing good conveying stability.

[0050] Usage process

[0051] The power motor 52 on the power component 5 drives the first gear 56 to rotate, which in turn drives the drive shaft 54 ​​connected to the second gear 57 to rotate. Two drive cams 42 on the drive frame 53 are positioned within two adjacent spiral grooves 43, and the drive cams 42 abut against the inner walls of the spiral grooves 43. The rotation of the drive shaft 54 ​​drives the drive cams 42 on the positioning fixture 2 to move along the spiral guide groove 55, converting the rotational driving force of the drive shaft 54 ​​into the linear motion of the positioning fixture 2, forming a structure similar to a lead screw and nut transmission. This pushes the positioning fixture 2 connected to the drive cams 42 to move, realizing the feeding and conveying of the positioning fixture 2. Simultaneously, since the positioning fixture 2 is connected to the conveyor belt 16 via a fixing member, multiple positioning fixtures 2 on the conveyor belt 16 move synchronously under the traction of one positioning fixture 2, thus forming the transmission of the positioning fixture 2. When the positioning fixture 2 moves to the moving frame 32 on the guide assembly 3... When the positioning fixture 2 is mounted on the fixed frame 31, the roller assembly 33 on it is positioned opposite to the upper and lower sides of the positioning fixture 2. A spring 39 is fitted on the guide rod 37, and a limit block 36 is provided at the free end of the guide rod 37. Under the reaction force of the spring 39, the roller assembly 33 on the movable frame 32 presses and positions the positioning fixture 2 on the roller assembly 33 of the fixed frame 31. At the same time, the guide roller 34 and the roller assembly 33 form a conveying channel 35 for transmitting the positioning fixture 2, which further improves the conveying accuracy of the positioning fixture 2 during the transmission process. The positions of the two guide components 3 can be used as the loading and unloading areas of the product 24, and the position between the two guide components 3 can be used as the detection area of ​​the product 24. The guide drive component 4 moves along the spiral guide groove 55 to push and convey the positioning fixture 2, realizing a high-speed drive and positioning integrated positioning module design, eliminating the need for secondary positioning and shortening the equipment running time.
