Description

Technical Field

[0001] The present invention belongs to the technical field of mobile phones, and specifically relates to a fixture device for an automatic production line of mobile phones. Background Art

[0002] With the rapid development of technology, the production of electronic products has adopted an automated method. During the automated production process of mobile phones, they need to be fixed to facilitate assembly and processing. Therefore, there is a mobile phone fixture. Placing the mobile phone inside the mobile phone fixture facilitates various processing and assembly operations on the mobile phone.

[0003] Currently, in the existing technologies, various methods for fixing mobile phone production have been proposed. For example, a Chinese patent with the publication number CN112040043A discloses an automatic clamping fixture and a clamping method for mobile phone production, which uses automatic clamping during mobile phone testing to reduce labor, save time, and improve efficiency.

[0004] In the above technical solution, the problem of automatic clamping is proposed and solved, but there are still some deficiencies. Most of the existing mobile phone fixtures transport and process the mobile phones with one side facing up through a conveyor belt, and cannot flip the mobile phone to perform assembly processing on its back. Usually, it is necessary to wait until it is transported to the next production line and then manually or mechanically flip and process it.

[0005] Therefore, the present invention provides a fixture device for an automatic production line of mobile phones. Summary of the Invention

[0006] In order to make up for the deficiencies of the existing technology and solve at least one technical problem proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A fixture device for a mobile phone automated production line according to the present invention includes a fixture body and a conveyor belt. A square groove is formed at the top of the fixture body, and a mounting block is fixedly connected to the middle of the square groove. A fixed shaft is fixedly connected to the top of the mounting block. Rotating shafts penetrate through and are rotatably connected to both ends of the square groove at the top of the fixture body. A positioning shaft is fixedly connected to one end of the rotating shaft. Circular holes are formed at both ends of the fixed shaft and are rotatably connected to the positioning shaft. Support side plates are placed on both sides of the conveyor belt. Mounting side plates are fixedly connected to the mutually close sides of the two support side plates. A sliding guide rail is fixedly connected to the side of the mounting side plate away from the support side plate. Rotating racks are provided at both the top and the bottom of the groove of the sliding guide rail. A rotating gear is fixedly connected to the end of the rotating shaft away from the positioning shaft. The rotating gear is slidably connected to the inner side of the sliding guide rail. The rotating gear meshes with the rotating rack. Support plates are fixedly connected to the side surfaces of both rotating shafts. During operation, the mobile phone to be processed is placed on the top of one support plate, and the fixture body is placed on the top of the conveyor belt for transportation. The rotating gear slides and is clamped into the interior of the sliding guide rail from the end of the sliding guide rail during transportation. The rotating racks are respectively located on the inner wall of the top and the inner wall of the bottom of the sliding guide rail. When the rotating gear slides inside the sliding guide rail, it meshes with a set of rotating racks at the top or a set of rotating racks at the bottom, so as to realize the forward rotation and reverse rotation of the rotating gear, drive the rotating shaft to rotate. The mounting block supports the fixed shaft, so that the rotating shaft rotates through the positioning shaft in the circular hole at the end of the fixed shaft, drives the support plate to rotate. When the two support plates rotate inward by ninety degrees simultaneously, the mobile phone is perpendicular to the fixture. When the support plate without the mobile phone rotates by one hundred and eighty degrees, this support plate covers the top of the mobile phone. Then, the two support plates are rotated in the reverse direction by one hundred and eighty degrees simultaneously, so that the mobile phone turns to the other side. At this time, the support plate on the top of the mobile phone is rotated by one hundred and eighty degrees to reset, and the mobile phone to be processed can be rotated to the top of another support plate to realize the flipping of the mobile phone and process the other side. In this way, it is not necessary to transfer and turn over through redundant machinery or manual labor in the middle, reducing labor and being convenient to operate with small errors.

[0008] Preferably, three auxiliary grooves are respectively opened at both ends of the top square groove of the jig body. An auxiliary block is clamped in the middle auxiliary groove, and side pressing blocks are clamped in the two side auxiliary grooves. Pulling springs are fixedly connected to the outer sides of the side pressing blocks and the auxiliary block. Two installation grooves are respectively opened in the side auxiliary grooves of the jig body, and the installation grooves are fixedly connected to the pulling springs. Rotating rollers are fixedly connected to the tops of the side pressing blocks and the auxiliary block. An annular groove is opened on the side of the rotating roller and a rotating ring is sleeved. A pushing plate is fixedly connected to the top of the sliding guide rail. A guiding groove is opened on the side of the pushing plate. The pushing plate is fixedly connected to the sliding guide rail. Two pressing plates are fixedly connected to the top of the jig body; during operation, the rotating ring closely adheres to the side wall of the pushing plate. The side wall of the pushing plate has a slope and two planes parallel to the side wall of the jig body. A pulling spring is arranged on one side of the side pressing block and the auxiliary block. When the jig body is transported on the top of the conveyor belt, the rotating ring moves on the side wall of the pushing plate, changing the distance between the side pressing block and the auxiliary block and the top square groove of the jig body. By pressing the side pressing block and the auxiliary block with the pressing plate, the side pressing block and the auxiliary block can be restricted, so that the side pressing block and the auxiliary block can only move back and forth in one direction. At the same time, the side away from the pulling spring of the side pressing block and the auxiliary block is a slope, which can prevent the side pressing block and the auxiliary block from vertically colliding with the side of the mobile phone. When the mobile phone is on the top of the support plate, the four corners of the mobile phone can be fixed by the side pressing block and the auxiliary block, avoiding deviation during processing and causing economic losses.

[0009] Preferably, four protective plates are fixedly connected to the top of the support plate and are centrosymmetric about the centers of the two support plates. The protective plates are in close contact with the top square groove of the jig body; during operation, when the mobile phone is turned over, due to the arrangement of the protective plates, the centrifugal force is prevented from throwing the mobile phone out. Due to the centrosymmetry of the protective plates and the support plates, the protective plates can be prevented from colliding with each other.

[0010] Preferably, a fixed bottom column is fixedly connected to the top of one support plate, and a fixed buckle is fixedly connected to the top of the other support plate. Telescopic columns are fixedly connected to both sides of the fixed bottom column. Fixed springs are fixedly connected to both sides of the fixed bottom column, and the other ends of the fixed springs are fixedly connected to a movable block. The movable block is mutually fitted with the fixed buckle. The fixed spring is movably sleeved on the side of the telescopic column. The other ends of the two telescopic columns away from the fixed bottom column are both movably clamped inside the movable block; during operation, the outer side of the movable block is fitted with the inner side of the fixed buckle. The top of the inner side of the fixed buckle is a slope. When the two support plates are perpendicular to the horizontal plane, the fixed bottom column is fixed, and the movable block is pushed inward by the fixed spring through the top of the fixed buckle, so that the movable block is clamped with the fixed buckle, making the side of the mobile phone perpendicular, which is convenient for performing tests such as charging.

[0011] Preferably, two inclined columns are fixedly connected to the front side wall of the top square groove of the jig body. Two slots are formed in the side of one support plate, and the slots are movably clamped with the inclined columns. A limiting bottom block is fixedly connected to the side of the support plate near the inclined columns. During operation, when the movable block needs to be disengaged from the fixed buckle, both support plates rotate towards the inclined columns. The movable block squeezes the fixed spring inward through the inclined columns and moves, so that the movable block and the fixed buckle are separated. The fixed buckle is clamped outside the inclined column, and the outward extension of the movable block is restricted by the limiting bottom block.

[0012] Preferably, a clamping groove is formed in the inner side surface of the auxiliary block, and the length of the bottom of the clamping groove is the same as the diameter of the rotating shaft. The opening of the clamping groove is wider outside and narrower inside. The auxiliary block is located on the top of the rotating shaft, and an annular sponge is provided on the side surface of the rotating shaft. During operation, when the mobile phone is vertical, it is fixed by the telescopic auxiliary block to avoid damage caused by inaccurate position during charging and other tests.

[0013] Preferably, a limiting plate is fixedly connected to the outside of the mounting block, and both ends of the limiting plate are fixedly connected to the inner wall of the jig body. The limiting plate is located at the bottom of the rotating shaft. During operation, the support plate is limited by the limiting plate to prevent the support plate from shifting downward, causing the mobile phone to tilt and unable to be processed.

[0014] Preferably, a sponge pad is fixedly connected to the bottom of the top square groove of the jig body, and the sponge pad is located at the bottom of the support plate. During operation, due to the arrangement of the sponge pad, it is avoided that the support plate rotates too fast, causing a large collision and damaging the internal parts of the mobile phone on the top.

[0015] Preferably, positioning columns are fixedly connected to the surface of the conveyor belt at equal intervals. Trapezoidal grooves are formed on both sides of the bottom of the jig body, and the positioning columns are trapezoidal. During operation, the jig body is clamped between two positioning columns to prevent the jig body from being stuck and stopped during transportation, and at the same time, the transportation state of the jig body is stabilized. When the jig body is installed, the trapezoidal groove on one side is first clamped with the positioning column through one end of the conveyor belt, and then the other positioning column is fixed by rotating the conveyor belt.

[0016] Preferably, a transport roller is rotatably connected to the inner side of the support side plate. The transport roller is located inside the conveyor belt. Fixed strips are fixedly connected to both sides of the jig body, and the fixed strips are located between the sliding guide rail and the conveyor belt. During operation, due to the arrangement of the transport roller and the fixed strips, it is avoided that the pressure on the jig body is too large, causing the top surface of the conveyor belt to sink.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. For the jig device of a mobile phone automated production line described in the present invention, by using a rotating gear and a rotating rack to rotate the rotating shaft, the mobile phone to be processed can be rotated from one support plate to the top of another support plate to achieve turning over the mobile phone, and the other side can be processed. In this way, it is not necessary to transfer and turn over through redundant machinery or manual labor in the middle, reducing labor force, being convenient to operate, and having small errors.

[0019] 2. For the jig device of a mobile phone automated production line described in the present invention, while the conveyor belt is transporting, the pushing plate is used to push the rotating ring through an inclined plane, and the side pressing blocks and auxiliary blocks are pushed out to fix the four corners of the mobile phone, avoiding the inclination of the mobile phone and causing inconvenience in processing.

Detailed implementation manner

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0034] Embodiment

[0035] Such as Figures 1 to 6As shown in the figure, a jig device for a mobile phone automated production line according to an embodiment of the present invention includes a jig body 1, a conveyor belt 30. A square groove is opened at the top of the jig body 1, and a mounting block 8 is fixedly connected to the middle of the square groove. A fixed shaft 9 is fixedly connected to the top of the mounting block 8. Rotating shafts 4 penetrate through and are rotatably connected to both ends of the square groove at the top of the jig body 1. A positioning shaft 7 is fixedly connected to one end of the rotating shaft 4. Circular holes are opened at both ends of the fixed shaft 9 and are rotatably connected to the positioning shaft 7. Support side plates 29 are placed on both sides of the conveyor belt 30. Mounting side plates 12 are fixedly connected to the mutually approaching sides of the two support side plates 29. A sliding guide rail 11 is fixedly connected to the side of the mounting side plate 12 away from the support side plate 29. Rotating racks 13 are provided at the top and bottom of the groove of the sliding guide rail 11. A rotating gear 5 is fixedly connected to the end of the rotating shaft 4 away from the positioning shaft 7. The rotating gear 5 is slidably connected to the inner side of the sliding guide rail 11. The rotating gear 5 meshes with the rotating rack 13. Support plates 6 are fixedly connected to the side surfaces of the two rotating shafts 4. During operation, the mobile phone to be processed is placed on the top of one support plate 6, and the jig body 1 is placed on the top of the conveyor belt 30 for transportation. When transporting, the rotating gear 5 slides and is clamped into the inside of the sliding guide rail 11 from the end of the sliding guide rail 11. The rotating racks 13 are respectively located on the inner walls of the top and bottom of the sliding guide rail 11. When the rotating gear 5 slides inside the sliding guide rail 11, it meshes with a set of rotating racks 13 at the top or a set of rotating racks 13 at the bottom, so as to realize the forward rotation and reverse rotation of the rotating gear 5, drive the rotating shaft 4 to rotate. The mounting block 8 supports the fixed shaft 9, so that the rotating shaft 4 rotates through the positioning shaft 7 in the circular hole at the end of the fixed shaft 9, drives the support plate 6 to rotate. When the two support plates 6 rotate inward by 90 degrees at the same time, the mobile phone is perpendicular to the jig. When the support plate 6 without the mobile phone rotates 180 degrees, this support plate 6 covers the top of the mobile phone. Then the two support plates 6 rotate 180 degrees in the reverse direction at the same time, so that the mobile phone turns to the other side. At this time, the support plate 6 on the top of the mobile phone rotates 180 degrees to reset, and the mobile phone to be processed can be rotated to the top of another support plate 6 to realize the flipping of the mobile phone, and the other side can be processed. In this way, it is not necessary to transfer and turn over through redundant machinery or manual labor in the middle, reducing labor and being convenient to operate with small errors.

[0036] As Figures 1 to 7As shown in the figure, three auxiliary grooves are respectively opened at both ends of the top square groove of the jig body 1. An auxiliary block 17 is clamped in the middle auxiliary groove, and side pressing blocks 16 are clamped in the two side auxiliary grooves. Pulling springs 18 are fixedly connected to the outer sides of the auxiliary block 17 and the side pressing blocks 16. Two installation grooves are respectively opened in the side auxiliary grooves of the jig body 1, and the installation grooves are fixedly connected to the pulling springs 18. Rotating rollers 19 are fixedly connected to the tops of the auxiliary block 17 and the side pressing blocks 16. An annular groove is opened on the side of the rotating roller 19, and a rotating ring 20 is sleeved in the annular groove. A pushing plate 14 is fixedly connected to the top of the sliding guide rail 11. A guiding groove is opened on the side of the pushing plate 14, and the pushing plate 14 is fixedly connected to the sliding guide rail 11. Two pressing plates 15 are fixedly connected to the top of the jig body 1. During operation, the rotating ring 20 is closely attached to the side wall of the pushing plate 14. A guiding groove is opened on the side of the pushing plate 14 close to the support plate 6, and the corners of the guiding groove are chamfered. A pulling spring 18 is provided on one side of the auxiliary block 17 and the side pressing blocks 16. When the jig body 1 is transported on the top of the conveyor belt 30, the rotating ring 20 moves on the side wall of the pushing plate 14 as the conveyor belt moves. When the rotating ring 20 is located in the guiding groove on the side of the pushing plate 14, the auxiliary block 17 and the side pressing blocks 16 are in the auxiliary grooves through the pulling springs 18. When the rotating ring 20 is not in the guiding groove, the pushing plate 14 pushes the rotating ring 20 to push the auxiliary block 17 and the side pressing blocks 16 out of the auxiliary grooves, changing the distance between the auxiliary block 17 and the side pressing blocks 16 and the top square groove of the jig body 1. By pressing the auxiliary block 17 and the side pressing blocks 16 with the pressing plates 15, the auxiliary block 17 and the side pressing blocks 16 can be restricted, so that the auxiliary block 17 and the side pressing blocks 16 can only move back and forth in one direction. At the same time, the sides of the auxiliary block 17 and the side pressing blocks 16 away from the pulling springs 18 are inclined surfaces, which can prevent the auxiliary block 17 and the side pressing blocks 16 from vertically colliding with the side of the mobile phone. When the mobile phone is on the top of the support plate 6, the four corners of the mobile phone can be fixed by the auxiliary block 17 and the side pressing blocks 16, avoiding deviation during processing and causing economic losses.

[0037] As Figure 2 shown, four protective plates 21 are fixedly connected to the top of the support plate 6, and the two support plates 6 are horizontally centrosymmetric about the midpoint of the fixed shaft 9. The protective plates 21 are closely attached to the top square groove of the jig body 1. During operation, when the mobile phone is turned over, due to the arrangement of the protective plates 21, the centrifugal force is prevented from throwing the mobile phone out. Since the two support plates 6 are horizontally centrosymmetric about the midpoint of the fixed shaft 9, the protective plates 21 can be prevented from colliding with each other.

[0038] As Figure 9As shown in the figure, a fixed bottom column 24 is fixedly connected to the top of one support plate 6, and a fixed buckle 22 is fixedly connected to the top of the other support plate 6. Telescopic columns 27 are fixedly connected to both sides of the fixed bottom column 24. Fixed springs 28 are fixedly connected to both sides of the fixed bottom column 24, and the other ends of the fixed springs 28 are fixedly connected to movable blocks 25. The movable blocks 25 are fitted with the fixed buckles 22. The fixed springs 28 are movably sleeved outside the telescopic columns 27. The other ends of the two telescopic columns 27 far from the fixed bottom column 24 are both movably clamped inside the movable blocks 25. During operation, the outer side of the movable block 25 is fitted with the inner side of the fixed buckle 22. The top inner side of the fixed buckle 22 is beveled. When the two support plates 6 are perpendicular to the horizontal plane, the movable block 25 is pushed by the fixed spring 28 to move towards the fixed bottom column 24. When passing through the top of the fixed buckle 22, the fixed spring 28 rebounds, causing the movable block 25 to be clamped with the fixed buckle 22, making the mobile phone vertical and facilitating tests such as charging.

[0039] As Figure 9 shown in the figure, two inclined columns 23 are fixedly connected to the front side wall of the square groove at the top of the fixture body 1. Two slots are formed in the side of one support plate 6, and the slots are movably clamped with the inclined columns 23. A limiting bottom block 26 is fixedly connected to the side of the support plate 6 near the inclined column 23. During operation, when the clamping between the movable block 25 and the fixed buckle 22 needs to be released, both support plates 6 rotate towards the side of the inclined column 23. The movable block 25 is pushed by the inclined column 23 to move inward to compress the fixed spring 28, causing the movable block 25 and the fixed buckle 22 to disengage. The fixed buckle 22 is clamped outside the inclined column 23. The limiting bottom block 26 restricts the outward extension of the movable block 25, causing the movable block 25 and the fixed buckle 22 to disengage. At this time, the support plate 6 at the top can be reset and rotated.

[0040] As Figure 7 and Figure 11 shown in the figure, a card slot is formed on the inner side surface of the auxiliary block 17, and the bottom length of the card slot is the same as the diameter of the rotating shaft 4. The opening of the card slot is wider outside and narrower inside. The auxiliary block 17 is located at the top of the rotating shaft 4. An annular sponge is provided on the side surface of the rotating shaft 4. During operation, when the mobile phone becomes vertical, the two sides of the two support plates 6 are fixed by the telescopic movement of the auxiliary block 17, preventing inclination during subsequent transportation and inaccurate positioning during tests such as charging, which may cause damage. The rotating shaft 4 is provided with an annular sponge to reduce friction and prevent wear on the side of the mobile phone when the mobile phone is vertical and rotated.

[0041] As Figure 5 shown in the figure, a limiting plate 10 is fixedly connected to the outside of the mounting block 8, and both ends of the limiting plate 10 are fixedly connected to the inner wall of the fixture body 1. The limiting plate 10 is located at the bottom of the rotating shaft 4. During operation, the support plate 6 is limited by the limiting plate 10 to prevent the support plate 6 from shifting downward, causing the mobile phone to tilt and unable to be processed.

[0042] As Figures 1 to 4As shown, a sponge pad 3 is fixedly connected to the bottom of the top square groove of the jig body 1, and the sponge pad 3 is located at the bottom of the support plate 6. During operation, through the setting of the sponge pad 3, when the support plate 6 rotates too fast, the impact force is reduced through the sponge pad 3 to protect the internal parts of the mobile phone on the top of the support plate 6.

[0043] As Figure 5 and Figure 10 shown, positioning columns 31 are fixedly connected to the surface of the conveyor belt 30 at equal intervals. Trapezoidal grooves are formed on both sides of the bottom of the jig body 1, and the positioning columns 31 are trapezoidal. During operation, the jig body 1 is clamped between the two positioning columns 31 to prevent the jig body 1 from being stuck and stopped during transportation, and at the same time, the transportation state of the jig body 1 is stabilized. When the jig body 1 is installed, the trapezoidal groove on one side is first clamped with the positioning column 31 through one end of the conveyor belt 30, and then the other positioning column 31 is rotated through the conveyor belt 30 to fix the trapezoidal groove on the other side of the jig body 1.

[0044] As Figure 10 shown, a transport roller 32 is rotatably connected to the inner side of the support side plate 29. The transport roller 32 is located inside the conveyor belt 30. Fixed strips 2 are fixedly connected to both sides of the jig body 1, and the fixed strips 2 are located between the sliding guide rail 11 and the conveyor belt 30. During operation, through the setting of the transport roller 32 and the fixed strips 2, the pressure on the jig body 1 is avoided, and the top surface of the conveyor belt 30 is prevented from sagging.

[0045] In the specific implementation of the embodiments of the present invention, the rotating rack 13, the pushing plate 14, and the rotating gear 5 should meet the installation conditions for the following steps of operation. Place the mobile phone to be processed on the top of the left support plate 6, and place the fixture body 1 on the top of the conveyor belt 30 for transportation. A guiding groove is provided on one side of the pushing plate 14 close to the support plate 6, and the corners of the guiding groove are chamfered. A pulling spring 18 is provided on one side of the auxiliary block 17 and the side pressing block 16. When the fixture body 1 is transported on the top of the conveyor belt 30, the rotating ring 20 moves on the side wall of the pushing plate 14 along with the conveyor belt. Initially, the rotating ring 20 is located outside the groove. The pushing plate 14 pushes the side pressing block 16 and the auxiliary block 17 so that the side pressing block 16 and the auxiliary block 17 are located at the four corners of the top of the mobile phone on the support plate 6 to fix the mobile phone for processing. After completion, the rotating ring 20 slides into the guiding groove through the chamfer, and the pulling spring 18 pulls the side pressing block 16 and the auxiliary block 17 to separate the side pressing block 16 and the auxiliary block 17 from the four corners of the top of the mobile phone. The rotating gear 5 slides and engages into the inside of the sliding guide rail 11 from the end of the sliding guide rail 11 during transportation. The rotating racks 13 are respectively located on the inner walls of the top and bottom of the sliding guide rail 11. The rotating gear 5 slides inside the sliding guide rail 11. The rotating gear 5 meshes with the rotating rack 13 at the top of a group to make the rotating gear 5 rotate in the reverse direction, and the rotating gear 5 meshes with the rotating rack 13 at the bottom of a group to make the rotating gear 5 rotate in the forward direction. The rotating gear 5 drives the rotating shaft 4 to rotate. The mounting block 8 supports the fixed shaft 9 so that the rotating shaft 4 rotates through the positioning shaft 7 in the circular hole at the end of the fixed shaft 9, driving the support plate 6 to rotate. The rotating ring 20 is closely attached to the side wall of the pushing plate 14. The right rotating gear 5 meshes with the top rotating rack 13 and rotates 180 degrees, making the right support plate 6 rotate 180 degrees in the reverse direction, so that the right support plate 6 covers the top of the mobile phone. Both rotating gears 5 mesh with the bottom rotating rack 13 and rotate 180 degrees, making the two support plates 6 rotate 180 degrees in the forward direction at the same time, turning the mobile phone to the right. At this time, the left rotating gear 5 meshes with the top rotating rack 13 and rotates 180 degrees, rotating the left support plate 6 180 degrees in the reverse direction to reset, and the mobile phone to be processed can be rotated to the top of another support plate 6 to realize flipping the mobile phone. After that, the rotating ring 20 slides out of the guiding groove through the chamfer again, and the pushing plate 14 pushes the side pressing block 16 and the auxiliary block 17 so that the side pressing block 16 and the auxiliary block 17 are located at the four corners of the top of the mobile phone on the support plate 6 to fix the mobile phone;When performing plug-in and other tests, the rotating ring 20 slides into the guiding groove, without fixing the mobile phone. The left rotating gear 5 meshes with the bottom rotating rack 13 and rotates forward by 90 degrees, and the right rotating gear 5 meshes with the top rotating rack 13 and rotates backward by 90 degrees, making the two support plates 6 perpendicular, fixing the mobile phone in the middle. When the mobile phone is perpendicular, the rotating ring 20 slides out of the guiding groove, pushing the auxiliary block 17, so that the card slot on the side of the auxiliary block 17 is inserted into the outside of the two support plates 6 to fix the two support plates 6 and prevent tilting. On the contrary, after charging is completed, the rotating ring 20 slides into the guiding groove, the auxiliary block 17 retracts, and the two rotating gears 5 and the rotating rack 13 mesh and rotate 90 degrees in the same direction, placing the mobile phone horizontally on the support plate. When manufacturing and assembling the mobile phone, according to the processing sequence and assembly requirements, multiple turning operations are required.

[0046] During operation, place the mobile phone to be processed on the top of a support plate 6, place the fixture body 1 on the top of the conveyor belt 30 for transportation, and the rotating gear 5 slides and engages with the inside of the sliding guide rail 11 from the end of the sliding guide rail 11 during transportation. The rotating racks 13 are respectively located on the inner walls of the top and bottom of the sliding guide rail 11. When the rotating gear 5 slides inside the sliding guide rail 11, it meshes with a set of rotating racks 13 at the top or a set of rotating racks 13 at the bottom, so as to realize the forward and reverse rotation of the rotating gear 5, drive the rotating shaft 4 to rotate. The mounting block 8 supports the fixed shaft 9, so that the rotating shaft 4 rotates through the positioning shaft 7 in the circular hole at the end of the fixed shaft 9, driving the support plate 6 to rotate. When the two support plates 6 rotate inward by 90 degrees at the same time, the mobile phone is perpendicular to the fixture. When the support plate 6 without the mobile phone placed rotates 180 degrees, this support plate 6 covers the top of the mobile phone. Then rotate the two support plates 6 in the reverse direction by 180 degrees at the same time to turn the mobile phone to the other side. At this time, rotate the support plate 6 at the top of the mobile phone 180 degrees to reset, and the mobile phone to be processed can be rotated to the top of another support plate 6 to realize the flipping of the mobile phone and process the other side. In this way, it is not necessary to transfer and turn over through redundant machinery or manual labor in the middle, reducing labor and being convenient to operate with small errors. The rotating ring 20 is closely attached to the side wall of the push plate 14. A guide groove is provided on the side of the push plate 14 close to the support plate 6, and the corners of the guide groove are chamfered. A pulling spring 18 is provided on one side of the auxiliary block 17 and the side pressing block 16. When the fixture body 1 is transported on the top of the conveyor belt 30, the rotating ring 20 moves on the side wall of the push plate 14 as the conveyor belt moves. When the rotating ring 20 is located in the guide groove on the side of the push plate 14, the auxiliary block 17 and the side pressing block 16 are in the auxiliary groove through the pulling spring 18. When the rotating ring 20 is not in the guide groove, the push plate 14 pushes the rotating ring 20 to push the auxiliary block 17 and the side pressing block 16 out of the auxiliary groove, changing the distance between the auxiliary block 17 and the side pressing block 16 and the square groove on the top of the fixture body 1. By pressing the auxiliary block 17 and the side pressing block 16 with the pressing plate 15, the auxiliary block 17 and the side pressing block 16 can be restricted, so that the auxiliary block 17 and the side pressing block 16 can only move back and forth in one direction. At the same time, the sides of the auxiliary block 17 and the side pressing block 16 away from the pulling spring 18 are inclined planes, which can prevent the auxiliary block 17 and the side pressing block 16 from colliding perpendicularly with the side of the mobile phone. When the mobile phone is on the top of the support plate 6, the four corners of the mobile phone can be fixed by the auxiliary block 17 and the side pressing block 16 to avoid deviation during processing and causing economic losses. When the mobile phone is turned over, through the setting of the protective plate 21, the centrifugal force can be prevented from throwing the mobile phone out. Since the two support plates 6 are horizontally centrosymmetric about the midpoint of the fixed shaft 9, the protective plates 21 can be prevented from colliding. The outside of the movable block 25 fits with the inside of the fixed buckle 22. The top of the inside of the fixed buckle 22 is an inclined plane. When the two support plates 6 are perpendicular to the horizontal plane, the movable block 25 is pushed by the fixed spring 28 to move towards the fixed bottom column 24. When passing through the top of the fixed buckle 22, the fixed spring 28 rebounds, so that the movable block 25 is clamped with the fixed buckle 22.Keep the mobile phone vertical for convenient charging and other tests. When it is necessary to unlock the engagement between the movable block 25 and the fixed buckle 22, both support plates 6 rotate towards the inclined column 23. The movable block 25 moves inward by squeezing the fixed spring 28 through the inclined column 23, so that the movable block 25 and the fixed buckle 22 are disengaged. The fixed buckle 22 is engaged with the outside of the inclined column 23. The movement of the movable block 25 outward is restricted by the limiting bottom block 26, so that the movable block 25 and the fixed buckle 22 are disengaged. At this time, the support plate 6 at the top can be rotated back to its original position. When the mobile phone is vertical, the two sides of the two support plates 6 are fixed by the telescopic movement of the auxiliary block 17 to prevent tilting during subsequent transportation, which may cause inaccurate positioning and damage during charging and other tests. The support plate 6 is limited by the limiting plate 10 to prevent the support plate 6 from shifting downward and causing the mobile phone to tilt, which may prevent processing. Through the setting of the sponge pad 3, when the support plate 6 rotates too fast, the impact force is reduced by the sponge pad 3 to protect the internal parts of the mobile phone on the top of the support plate 6. The fixture body 1 is engaged between the two positioning columns 31 to prevent the fixture body 1 from being stuck and stopped during transportation, and at the same time, the transportation state of the fixture body 1 is stabilized. When the fixture body 1 is installed, the trapezoidal groove on one side is first engaged with the positioning column 31 through one end of the conveyor belt 30, and then the other positioning column 31 is fixed by rotating the conveyor belt 30 to fix the trapezoidal groove on the other side of the fixture body 1. Through the setting of the transport roller 32 and the fixed strip 2, it is avoided that the pressure on the fixture body 1 is too large, causing the top surface of the conveyor belt 30 to sink.
