[0031] Example

[0032] See also Figure 1-9 , the present invention provides the following technical solutions:

[0033] A film laminating device for film laminating equipment includes a base 1, a driving component 2 and a film pressing component 4 are installed on the top of the base 1, the driving component 2 is located on one side of the film pressing component 4, a bearing component 3 is installed on the top of the driving component 2, a placement component 6 is installed on the top of the bearing component 3, the placement component 6 is multiple groups, a product 9 is placed on the top of the placement component 6, the placement component 6 is used to carry the product 9, the driving component 2 is used to drive the bearing component 3 to rotate, thereby adjusting the position of the placement component 6 and the product 9, the film pressing component 4 is used to apply film to the product 9, and a blowing component 5 is provided on the side of the driving component 2 away from the film pressing component 4 , the blowing assembly 5 is installed on the top of the base 1, and the blowing assembly 5 is used to blow off the dust on the product 9. The top of the base 1 is installed with a positioning assembly 7 and a guide assembly 8. The positioning assembly 7 and the guide assembly 8 are both located between the blowing assembly 5 and the film pressing assembly 4 and on both sides of the driving assembly 2. The positioning assembly 7 is located between the blowing assembly 5 and the driving assembly 2, and the guide assembly 8 is located between the film pressing assembly 4 and the driving assembly 2. The guide assembly 8 is used to support the bearing assembly 3, thereby ensuring that the bearing assembly 3 and the placement assembly 6 remain horizontal. After each rotation of the bearing assembly 3 by a certain angle, the positioning assembly 7 is used to position the bearing assembly 3;

[0034] The bearing assembly 3 includes a turntable 31, which is located above the driving assembly 2. A top plate 34 is installed on the top of the turntable 31, and a column 33 is installed on the top of the top plate 34. The top of the column 33 is connected to a bracket 32, and the bottom of the bracket 32 ​​is connected to the top of the turntable 31. The column 33 is used to support the bracket 32, and the bracket 32 ​​supports the turntable 31 in multiple positions, thereby ensuring the levelness of the turntable 31 in multiple positions. The turntable 31 is used to carry the placement assembly 6;

[0035] The driving assembly 2 includes a mounting base 21, which is mounted on the top of the base 1. A motor 22 is mounted on the top of the mounting base 21. The output end of the motor 22 is connected to the bottom of the turntable 31. The mounting base 21 is used to mount and fix the motor 22, and the motor 22 is used to drive the turntable 31 to rotate.

[0036] Multiple groups of placement components 6 are evenly installed on the top of the turntable 31. The placement components 6 include a bearing seat 61, which is installed on the top of the turntable 31. A placement plate 65 is installed on the top of the bearing seat 61. The top of the placement plate 65 is evenly opened with placement grooves 68. The interior of the placement grooves 68 is penetrated by a carrying column 62. The product 9 is sleeved on the top of the carrying column 62. The carrying column 62 is used to carry the product 9. The carrying column 62 is positioned by the placement groove 68 opened on the placement plate 65. The placement plate 65 is fixed to the top of the turntable 31 through the bearing seat 61.

[0037] The outer diameter of the support column 62 is less than or equal to the minimum inner diameter of the product 9. The top of the support column 62 is provided with an arc-shaped portion 64. The lowest point of the top of the product 9 is horizontally set as the reference plane A, and the highest point of the top of the product 9 is horizontally set as the reference plane B. There is an angle α between the axial directions of the reference plane A and the reference plane B. The top of the arc-shaped portion 64 is horizontally set as the reference plane C, and the lowest point of the arc-shaped portion 64 is horizontally set as the reference plane D. There is an angle β between the axial directions of the reference plane C and the reference plane D. The angle α is within the angle range of the angle β. When the product 9 is sleeved on the top of the support column 62, the arc-shaped portion 64 fits the inner wall of the product 9. Since there is an angle α between the highest and lowest points of the product 9, and there is an arc angle at the top of the product 9, when the diameter of the product 9 is larger than the diameter of the supporting column 62, the supporting column 62 can also fit with the inner wall of the product 9 through the arc portion 64, thereby ensuring that the supporting column 62 and the product 9 are continuously fitted together. However, there is a gap between the middle of the internal top wall of the product 9 and the middle of the top surface of the supporting column 62. When the film pressing component 4 presses down on the product 9 to apply the film, this gap space is reduced, and the product 9 generates a reverse force. Moreover, when the contact position between the film pressing component 4 and the product 9 moves upward, the product 9 generates an extrusion force on the film pressing component 4 through the reverse force, thereby playing a role in maintaining pressure.

[0038] Vacuum holes 66 are evenly provided on the top of the carrier 61, and air pipes 63 are evenly provided on the outer walls of the vacuum holes 66. The air pipes 63 are correspondingly provided and communicate with the vacuum holes 66. The air pipes 63 are correspondingly provided and communicate with the vacuum holes 66. The air pipes 63 are correspondingly provided and communicate with the carrier column 62. The carrier column 62 is communicated with the vacuum holes 66, and the air pipes 63 are communicated with an external suction device. When the product 9 is fitted and connected with the carrier column 62, there is a gap between the middle of the top wall of the product 9 and the middle of the top surface of the carrier column 62. The external suction device extracts the air in the vacuum holes 66 and the gap, causing negative pressure to be generated in the gap. This negative pressure adsorbs the product 9 on the carrier column 62, thereby ensuring the stability of the fitting connection between the product 9 and the carrier column 62 and preventing the product 9 from shifting.

[0039] When the cam 73 is in the closed position, the cam 73 is in the closed position, and the cam 73 is in the closed position, so that the cam 73 is in the closed position, and the cam 73 is in the closed position, so that the cam 73 is in the closed position, and the cam 73 is in the closed position, so that the cam 73 is in the closed position, and the cam 73 is in the closed position.

[0040] The guide assembly 8 includes a base 81 mounted on the top of the base 1 and located below the turntable 31. The top of the base 81 is rotatably connected to a pulley 82. The outer wall of the pulley 82 is in contact with the bottom of the turntable 31. When the turntable 31 rotates, the pulley 82 slides on the bottom of the turntable 31, thereby guiding the turntable 31. The base 81 and the pulley 82 support the turntable 31, thereby ensuring that the turntable 31 is level.

[0041] The film pressing assembly 4 includes a base 41, which is installed on the top of the base 1. One side of the base 41 is connected to a mounting plate 42. A film pressing cylinder 47 is installed on the top of the mounting plate 42. The piston rod of the film pressing cylinder 47 is connected to a slide plate 43. The bottom of the slide plate 43 is connected to a connecting plate 44. The bottom of the connecting plate 44 is provided with a bottom plate 45. A plurality of pressure heads 46 are installed at the bottom of the connecting plate 44. The bottoms of the plurality of pressure heads 46 pass through the top of the bottom plate 45. There is a gap between the bottom plate 45 and the connecting plate 44. When a placement assembly 6 drives the corresponding product 9 to move to the position of the film pressing assembly 4, the film pressing cylinder 47 drives the slide plate 43, the connecting plate 44, the bottom plate 45 and the pressure head 46 to move downward, causing the pressure head 46 to squeeze the film on the product 9, and the gap between the bottom plate 45 and the connecting plate 44 is reduced and fits together, thereby limiting the downward movement distance of the pressure head 46.

[0042] The blowing assembly 5 includes a second base 51, which is evenly arranged and mounted on the top of the base 1. A fan 52 is hingedly mounted on the top of the second base 51. The air outlet of the fan 52 is close to one side of the supporting assembly 3. When the turntable 31 drives the placement assembly 6 and the product 9 to rotate, the fan 52 blows off the dust on the top of the product 9, thereby ensuring that the product 9 does not absorb dust when the film is applied;

[0043] Specifically, the film laminating carrier is connected to the control system, which controls the operation of the film laminating carrier. The control system controls the motor 22 to drive the turntable 31 to rotate, and the turntable 31 drives the multiple groups of placement components 6 to rotate and displace. At the same time, when the turntable 31 rotates, it drives the corresponding positioning plates 74 to rotate, so that the multiple positioning plates 74 are indirectly rotated to the top of the film pressing component 4 and the positioning component 7. In the initial state, the spring rod 73 is disengaged from the second positioning hole 75. When a group of placement components 6 rotates to a position close to the positioning component 7, the carrying plate 72 drives the spring rod 73 to move up and insert it into the second positioning hole 75, thereby positioning the turntable 31. At this time, the turntable 31 is in a stationary state.

[0044] The external loading robot puts the product 9 on the top of the carrier column 62. When the product 9 is put on the top of the carrier column 62, the curved portion 64 fits the inner wall of the product 9. Since there is an angle α between the highest and lowest points of the product 9, there is an arc angle at the top of the product 9. Therefore, when the diameter of the product 9 is larger than the diameter of the carrier column 62, the carrier column 62 can also fit the inner wall of the product 9 through the curved portion 64, thereby ensuring that the carrier column 62 and the product 9 are continuously fitted together. There is a gap between the middle of the inner top wall of the product 9 and the middle of the top surface of the carrier column 62.

[0045] The air pipe 63 is connected to an external suction device. When the product 9 is attached to the support column 62, the external suction device extracts air from the vacuum holes 66 and the gap between the middle of the top wall of the product 9 and the middle of the top surface of the support column 62, generating negative pressure in the gap. This negative pressure adsorbs the product 9 onto the support column 62, thereby ensuring the stability of the attachment between the product 9 and the support column 62 and preventing the product 9 from shifting.

[0046] After the product 9 is placed, the positioning assembly 7 is disengaged from the turntable 31, and the motor 22 drives the turntable 31 to continue rotating. When the next set of placement assemblies 6 moves to the positioning assembly 7, the positioning assembly 7 positions the turntable 31 again, and the external loading robot loads the next set of placement assemblies 6.

[0047] When the placement assembly 6 with the product 9 placed thereon moves to the position of the film pressing assembly 4, the film pressing cylinder 47 drives the slide plate 43, the connecting plate 44, the bottom plate 45 and the pressing head 46 to move downward, causing the pressing head 46 to press the product 9 to apply the film. Due to the gap between the bottom plate 45 and the connecting plate 44, when the bottom plate 45 moves downward and fits into the top of the placement assembly 6 corresponding to the turntable 31, the gap between the bottom plate 45 and the connecting plate 44 is reduced and fits into each other, thereby limiting the downward movement distance of the pressing head 46.

[0048] When the pressing head 46 presses the product 9 downwards to apply the film, the gap between the middle of the top wall of the product 9 and the middle of the top surface of the support column 62 is reduced, and the product 9 generates a reverse force. When the contact position between the film pressing assembly 4 and the product 9 moves upwards, the product 9 generates a squeezing force on the film pressing assembly 4 through the reverse force, thereby maintaining the pressure.

[0049] When the turntable 31 rotates, the pulley 82 slides at the bottom of the turntable 31, thereby guiding the turntable 31, and the base 81 and the pulley 82 support the turntable 31, thereby ensuring that the turntable 31 is level, and the fan 52 blows off the dust on the top of the product 9, thereby ensuring that the product 9 does not absorb dust when the film is applied.
