[0004] The utility model is proposed in view of the deficiencies in the prior art. Utility Model Content

[0025] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 5A finely adjustable composite preform suction pen is shown, comprising a device body 1, wherein the device body 1 comprises a preform transfer assembly 2 for transferring a preform to a mold, wherein the preform transfer assembly 2 comprises an adjustment assembly 4 movably connected to the device body 1, and a preform suction pen assembly 5 located on the adjustment assembly 4 and for adsorbing the preform, and when the adjustment assembly 4 is adjusted, the preform suction pen assembly 5 can move relatively to align with the mold position;

[0027] The utility model discloses a finely adjustable preform composite suction pen. By arranging an adjustment component and a preform suction pen component connected to the adjustment component on a device body, when the preform suction pen component is not aligned with the mold position, the user can adjust the adjustment component to make the preform suction pen component move relatively, so that the preform suction pen component can be aligned with the position of the mold and the preform on the preform suction pen component can be accurately placed into the mold, which effectively solves the problem of using a preform suction pen to absorb tiny preforms and transfer them to the mold for compression molding in the existing process. Due to the tiny size of the preform and the complex operating environment, it is often difficult to accurately align the preform suction pen with the mold when docking, resulting in a deviation in the position of the preform in the mold, so that the lens finally formed by the preform is eccentric.

[0028] By providing the adjustment component, the relative position of the preform suction pen component can be finely adjusted so that the preform suction pen component can adapt to molds of different sizes, shapes and positions, which is beneficial to improving the versatility and practicality of the device body.

[0029] like Figures 1 to 5 The adjustment assembly 4 shown includes a first adjustment mechanism 41 for leveling the angle and connected to the device body 1, and a second adjustment mechanism 42 connected to the first adjustment mechanism 41 and rotatable relative to the first adjustment mechanism 41;

[0030] Furthermore, the first adjustment mechanism 41, the second adjustment mechanism 42 and the preform suction pen assembly 5 are connected in sequence. The user adjusts the first adjustment mechanism 41 to change the angle of the second adjustment mechanism 42 relative to the first adjustment mechanism 41, thereby ensuring that the preform suction pen assembly 5 and the mold surface remain horizontal or at a specific angle. The precise angle adjustment of the second adjustment mechanism 42 by the first adjustment mechanism 41 can minimize the preform position offset caused by angle deviation, thereby improving the manufacturing accuracy of the lens.

[0031] Furthermore, the second adjustment mechanism 42 is connected to the first adjustment mechanism 41, and the second adjustment mechanism 42 can rotate relative to the first adjustment mechanism 41, so that the preform suction pen assembly 5 on the second adjustment mechanism 42 can rotate along the corresponding horizontal plane, thereby ensuring that the preform suction pen assembly 5 is aligned with the position of the mold, which is beneficial to improving the overall flexibility and adaptability of the device.

[0032] Furthermore, by adjusting the horizontal position of the preform suction pen assembly 5 through the second adjustment mechanism 42 and adjusting the specific angle of the preform suction pen assembly 5 through the first adjustment mechanism 41, the scrap rate caused by the misalignment of the preform suction pen assembly 5 and the mold position is reduced, which is beneficial to improving the production efficiency and quality of the lens.

[0033] like Figures 1 to 5 The second adjustment mechanism 42 shown includes a pen suction transition plate 421 connected to the preform pen suction assembly 5, a correction plate assembly 422 located near the first adjustment mechanism 41, and a locking screw 423 for connecting the pen suction transition plate 421 and the correction plate assembly 422. A gap is also provided between the correction plate assembly 422 and the pen suction transition plate 421 for the pen suction transition plate 421 to rotate relative to each other.

[0034] Furthermore, the preform pen suction assembly 5 is located on the pen suction transition plate 421 so that the preform pen suction assembly 5 can maintain an accurate position when the pen suction transition plate 421 rotates relative to it. The direct connection between the preform pen suction assembly 5 and the pen suction transition plate 421 helps to reduce errors caused by loose or worn connectors.

[0035] Specifically, the correction plate assembly 422 is connected to the suction pen transition plate 421 through a locking screw 423. When the suction pen transition plate 421 needs to be rotated to adjust the position of the preform suction pen assembly 5, the user only needs to twist the locking screw 423, and the suction pen transition plate 421 rotates accordingly with the rotation of the locking screw 423, thereby changing the position of the preform suction pen assembly 5.

[0036] Furthermore, the shapes of the pen suction transition plate 421 and the correction plate assembly 422 are both cylindrical, and the cross section of the correction plate assembly 422 is smaller than the cross section of the pen suction transition plate 421 .

[0037] Furthermore, a protrusion is provided on the side of the suction pen transition plate 421 close to the correction plate assembly 422, and a groove adapted to the protrusion is provided on the side of the correction plate assembly 422 close to the suction pen transition plate 421; or a groove is provided on the side of the suction pen transition plate 421 close to the correction plate assembly 422, and a protrusion adapted to the groove is provided on the side of the correction plate assembly 422 close to the suction pen transition plate 421, and a gap is located between the protrusion and the groove.

[0038] like Figures 1 to 5 The preform suction pen assembly 5 shown includes a vacuum joint 51 located on the outer wall of the suction pen transition plate 421, and a preform suction pen 52 located on the side of the suction pen transition plate 421 close to the mold and cooperating with the vacuum joint 51 to suck the preform;

[0039] Furthermore, the vacuum connector 51 is circumferentially arranged along the outer wall of the suction pen transition plate 421, and the number of the vacuum connectors 51 corresponds one-to-one to the number of the preform suction pens 52, which effectively ensures that each preform can be stably and effectively adsorbed. The one-to-one correspondence between the number of the vacuum connectors 51 and the number of the preform suction pens 52 avoids the problem of uneven or insufficient adsorption force caused by sharing the vacuum source, thereby improving the stability and reliability of the operation; secondly, the vacuum connector 51 is circumferentially arranged along the outer wall of the suction pen transition plate 421 to make the entire system more compact, which is conducive to saving space.

[0040] Furthermore, by means of vacuum adsorption, the preform suction pen 52 can stably adsorb the preform, thereby preventing the preform from sliding or falling off during transportation, and effectively ensuring the stability and reliability of production.

[0041] Furthermore, by adopting the vacuum adsorption method, the preform suction pen 52 can adapt to preforms of different shapes, sizes and materials, and has strong versatility and adaptability.

[0042] like Figures 1 to 5 The first adjustment mechanism 41 shown includes a first transition plate 411 located on the device body 1, and a first screw assembly 412 for connecting the first transition plate 411 and the correction plate assembly 422;

[0043] Furthermore, the first screw assembly 412 serves as a connecting piece, and the user can use the first screw assembly 412 to make fine adjustments to the positions of the first transition plate 411 and the correction plate assembly 422 .

[0044] Specifically, the user can accurately control the relative position and angle of the first transition plate 411 with respect to the correction plate assembly 422 by adjusting the tightness of the first screw assembly 412, thereby achieving a high degree of adjustment flexibility and accuracy.

[0045] like Figures 1 to 5 The pen suction transition plate 421, the correction plate assembly 422 and the first transition plate 411 close to the correction plate assembly 422 are all cylindrical and arranged along the same central axis;

[0046] Furthermore, the first transition plate 411, the correction plate assembly 422 and the suction pen transition plate 421 are connected in sequence, and the suction pen transition plate 421, the correction plate assembly 422 and the side of the first transition plate 411 close to the correction plate assembly 422 are all cylindrical, and the size of the cross-section of the first transition plate 411 is the same as the size of the cross-section of the correction plate assembly 422. The arrangement along the same central axis allows users to assemble and disassemble more easily, which helps to simplify the installation process.

[0047] like Figures 1 to 5The first transition plate 411 shown is provided with a circular hole 410 located at the center of the circle and penetrating the first transition plate 411, the first screw assembly 412 includes a plurality of first screws distributed along the circumference of the circular hole 410, and the locking screw 423 is arranged along the same central axis as the circular hole 410;

[0048] Specifically, when the user needs to adjust the position of the suction pen transition plate 421 relative to the correction plate assembly 422 through the locking screw 423, the locking screw 423 on the correction plate assembly 422 can be screwed through the circular hole 410; secondly, the locking screw 423 is located at the center of the correction plate assembly 422, and the first screw is distributed circumferentially along the outer peripheral side of the circular hole 410, which is conducive to maintaining the overall accuracy and consistency of the device.

[0049] Furthermore, as a preferred method but not a limitation of the utility model, the number of first screws is four, and the cross-section of the first screws distributed on the first transition plate 411 is rectangular, so that the user can fine-tune four positions on the first transition plate 411 through the first screws, and the multi-point adjustment method greatly improves the flexibility and accuracy of the adjustment. The user can accurately adjust the relative position and angle of the correction plate assembly 422 to the first transition plate 411 according to actual needs.

[0050] Furthermore, the symmetrically arranged first screws effectively ensure uniform stress on the first screw assembly 412 when fixing the first transition plate 411, thereby improving the stability of the entire structure. The rectangular cross-sectional layout also helps to disperse stress and prevent deformation or damage caused by excessive stress on a single point.

[0051] like Figures 1 to 5 The device body 1 shown further includes a driving component 3 connected to the preform transport component 2 to drive the preform transport component 2 to approach or move away from the mold;

[0052] Furthermore, by providing a driving assembly 3, the moving distance and speed of the preform transfer assembly 2 can be accurately controlled, effectively ensuring that the preform can accurately and smoothly approach or move away from the mold, avoiding damage or production accidents caused by improper positioning or uneven moving speed.

[0053] Furthermore, through the automated control of the drive assembly 3, the preform transfer process can be completed quickly, reducing the time and error of manual operation, which is beneficial to improving production efficiency.

[0054] like Figures 1 to 5 The driving assembly 3 shown includes a driving cylinder 31 and a guide rail assembly 32 connected to the output end of the driving cylinder 31;

[0055] Furthermore, the output end of the driving cylinder 31 is connected to the guide rail assembly 32, which can quickly and directly transmit the thrust or pull generated by the cylinder to the guide rail assembly 32, thereby achieving efficient transportation of the preform.

[0056] Furthermore, the driving cylinder 31 has the characteristic of fast response speed. The driving cylinder 31 can complete the telescopic action in a short time, so that the preform transfer assembly 2 can quickly approach or move away from the mold.

[0057] Optionally, in some embodiments, the drive assembly includes a servo motor, a hydraulic cylinder, or an electromagnetic device.

[0058] Furthermore, by setting up the guide rail assembly 32 to provide precise guiding function for the preform transfer assembly 2, it is effectively ensured that the preform transfer assembly 2 moves in a straight line along a predetermined trajectory under the action of the driving cylinder 31, avoiding possible deviation and shaking, thereby improving the accuracy and stability of transfer.

[0059] Furthermore, the guide rail assembly 32 has a high load-bearing capacity and is capable of bearing the weight of the preform transfer assembly 2 and its load while ensuring smooth movement.

[0060] Furthermore, the guide rail assembly 32 realizes the guiding function by rolling or sliding, which can significantly reduce friction and wear compared to direct friction contact, and effectively extend the service life of the equipment.

[0061] like Figures 1 to 5 The driving assembly 3 shown further includes a buffer assembly 33 connected to the output end of the driving cylinder 31, and the preform transfer assembly 2 is connected to the output end of the driving cylinder 31 through the buffer assembly 33;

[0062] Specifically, the buffer assembly 33 is located on one side of the output end of the driving cylinder 31 , and the guide rail assembly 32 is located on the other side of the output end of the driving cylinder 31 .

[0063] Furthermore, when the driving cylinder 31 pushes the preform transfer assembly 2 towards or away from the mold, the buffer assembly 33 can effectively reduce the impact force caused by the speed change, thereby avoiding the impact force from causing damage to the preform transfer assembly 2 and the mold. The buffer assembly 33 can absorb these impact forces and effectively ensure that the transfer process is smoother and safer.

[0064] Furthermore, due to the effect of the buffer assembly 33, the impact and vibration to which the preform is subjected during the entire transportation process are greatly reduced. The buffer assembly 33 can not only protect the preform from physical damage, but also avoid poor appearance caused by over-pressure contact between the preform and the mold.

[0065] Optionally, in some embodiments, the buffer component 33 may be a spring component, a shock absorbing pad, a rubber buffer, etc.

[0066] Further, as a preferred embodiment of the present invention but not limitation, the buffer assembly 33 is a buffer cylinder, which is located on the output end of the driving cylinder and one end of which is connected to the preform transfer assembly 2 .

[0067] The implementation method of this embodiment is as follows:

[0068] A finely adjustable composite preform suction pen comprises a device body 1, the device body 1 comprises a preform transport component 2, the preform transport component 2 comprises an adjustment component 4 movably connected to the device body 1, and a preform suction pen component 5 located on the adjustment component 4 and used for adsorbing the preform, the adjustment component 4 comprises a first adjustment mechanism 41 connected to the device body 1, and a second adjustment mechanism 42 connected to the first adjustment mechanism 41, the preform suction pen component 5 is located on the second adjustment mechanism 42, and a user can adjust the first adjustment mechanism 41 to change the angle of the second adjustment mechanism 42 relative to the first adjustment mechanism 41, so as to ensure that the preform suction pen component 5 is kept close to the mold surface. The second adjusting mechanism 42 is held horizontally or at a specific angle, and then the second adjusting mechanism 42 can rotate relative to the first adjusting mechanism 41, so that the preform suction pen assembly 5 on the second adjusting mechanism 42 can rotate along the corresponding horizontal plane, thereby ensuring that the preform suction pen assembly 5 is aligned with the position of the mold, effectively solving the problem of using a preform suction pen to absorb tiny preforms and transfer them to the mold for compression molding in the existing process. Due to the small size of the preform and the complex operating environment, it is often difficult to accurately align the preform suction pen with the mold when docking, resulting in a deviation in the position of the preform in the mold, so that the lens finally formed by the preform is eccentric.

[0069] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
