[0037] The realization, functional features and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0038] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Referring to Figure 1 , a manufacturing device for marking balls provided by the present invention includes: a first model component 1, a second model component 2, a clamping component 3 and a bottom mold component 4. The first model component 1 is installed on a driving device 5. Multiple blank hemispheres can be installed on the first model component 1. The second model component 2 is installed on the bottom mold component 4. The clamping component 3 is arranged between the first model component 1 and the second model component 2. Multiple reflective films can be clamped in the clamping component 3. Driven by the driving device 5, the first model component 1 abuts against the second model component 2. Under the pressing action of the first model component 1 and the second model component 2, the reflective film adheres to the surface of the blank hemisphere.

[0041] As described above, the manufacturing device for the marked balls provided in this embodiment includes a first model component 1, a second model component 2, a clamping component 3, and a bottom mold component 4. Among them, the first model component 1 is assembled on an external power device, such as a press or a telescopic cylinder. The two can be assembled through assembly methods such as screw connection or snap connection so that when the driving device 5 works, it can drive the first model component 1 to move to achieve the pressing or separation of the first model component 1 and the second model component 2. A plurality of blank hemispheres can be installed on the first model component 1. The specific setting method can be a clamping method or a sleeving method. The specific installation method is not specifically limited in this application, as long as it is ensured that the blank hemispheres do not shake during the process of being installed on the first model component 1 and moving with the first model component 1; a clamping component 3 is arranged between the first model component 1 and the second model component 2, and a reflective film is arranged in the clamping component 3 corresponding to each blank hemisphere. Under the action of the driving device 5, the first model component 1 continuously moves in the direction of the first model component 1, which will cause the blank hemispheres installed on the first model component 1 to first contact the reflective film. As the first model component 1 continues to move, finally, the blank hemispheres will abut against the second model component 2. Therefore, the reflective film will be wrapped on the surface of the blank hemispheres, achieving the film pasting work for a plurality of blank hemispheres through a single pressing action, which can greatly improve the generation efficiency of the marked balls.

[0042] Referring to Figure 2 , in one embodiment, the first model component 1 includes a pressing plate 11. A connecting portion 12 is arranged on the side of the pressing plate 11 away from the second model component 2, and a plurality of mounting portions 13 are arranged on the side of the pressing plate 11 close to the second model component 2. The blank hemispheres are installed on the mounting portions 13.

[0043] As described above, the first model component 1 includes a pressing plate 11, a connecting portion 12, and a mounting portion 13. Among them, the pressing plate 11 is an intermediate connecting member between the connecting portion 12 and the mounting portion 13. The connecting portion 12 and the mounting portion 13 are respectively installed on both sides of the pressing plate 11. The pressing plate 11 is connected to the driving device 5 through the connecting portion 12. Specifically, threads or threaded holes can be provided on the connecting portion 12. At the assembly position of the driving device 5 and the connecting portion 12, a threaded hole matching the threads provided on the connecting portion 12, or a screw matching the threaded holes provided on the connecting portion 12 is provided. The connecting portion 12 is fixed on the driving device 5 by means of threaded connection. Further, snap structures or buckles can also be respectively provided at the assembly positions of the connecting portion 12 and the driving device 5, and the two can also be assembled by means of snap connection or buckling;

[0044] On one side of the pressing plate 11 close to the second model component 2, a plurality of mounting parts 13 are provided. Among them, each mounting part 13 can hold a white embryo hemisphere that needs to be film-coated. Driven by the driving device 5, the white embryo hemisphere can move along with the first model component 1 for film coating.

[0045] In one embodiment, a plurality of limiting columns 14 are further provided on the side of the pressing plate 11 close to the second model component 2. A compression spring is arranged on the limiting column 14. During the process that the first model component 1 abuts against the second model component 2, the compression spring abuts against the clamping component 3.

[0046] As described above, a plurality of limiting columns 14 are further provided on the side of the pressing plate 11 close to the second model component 2. Among them, a compression spring is sleeved on each limiting column 14. The length of the compression spring is greater than the length of the mounting part 13. So that during the process that the first model component 1 continuously approaches the second model component 2, the compression spring can abut against the clamping component 3, enabling the first pressing plate 31 and the second pressing plate 32 in the clamping component 3 to clamp the reflective film. Furthermore, during the process of fitting the white embryo hemisphere and the reflective film, the reflective film can always be in a taut state, enabling the reflective film to be closely fitted to the white embryo hemisphere and avoiding the formation of wrinkles when the reflective film is fitted to the white embryo hemisphere.

[0047] Refer to Figure 3 and Figure 4 , in one embodiment, the clamping component 3 includes a first pressing plate 31 and a second pressing plate 32. A plurality of first through holes 311 are provided on the first pressing plate 31. Second through holes 321 matching the first through holes 311 are correspondingly provided on the second pressing plate 32. The reflective film is laid between the first through holes 311 and the second through holes 321 and covers the first through holes 311 and the second through holes 321.

[0048] As described above, the clamping assembly 3 includes a first pressing plate 31 and a second pressing plate 32. The first pressing plate 31 and the second pressing plate 32 are stacked between the first model assembly 1 and the second model assembly 2. A plurality of first through holes 311 are provided on the first pressing plate 31 corresponding to the plurality of mounting portions 13 in the first model assembly 1. Similarly, a plurality of second through holes 321 are provided on the second pressing plate 32 corresponding to the plurality of mounting portions 13 and the first through holes 311 in the first model assembly 1. The first through holes 311 and the second through holes 321 are both circular holes, and the diameters of the first through holes 311 and the second through holes 321 are the same, and are both larger than the diameter of the groove in the second model assembly 2 for accommodating the blank hemisphere; and the diameters of the first through holes 311 and the second through holes 321 are also larger than the diameter of the blank hemisphere. The plurality of first through holes 311 on the first pressing plate 31 correspond to the plurality of second through holes 321 provided on the second pressing plate 32 one by one, that is, one first through hole 311 corresponds to one second through hole 321, and the central axes of the two coincide. Similarly, each first through hole 311 also corresponds to one mounting portion 13, and the central axis of the mounting portion 13 also coincides with the central axes of the first through hole 311 and the second through hole 321. A reflective film is covered at each corresponding position of the first through hole 311 and the second through hole 321 between the first pressing plate 31 and the second pressing plate 32. During the film pasting process, after each blank hemisphere touches the corresponding reflective film at the same time, it continues to extend into the second model assembly 2 until the reflective film wraps the spherical surface of the entire blank hemisphere.

[0049] In one embodiment, an annular protrusion 312 surrounding the first through hole 311 is provided on the side of the first pressing plate 31 facing the second pressing plate 32, and an annular groove 322 surrounding the second through hole 321 is provided on the side of the second pressing plate 32 facing the first pressing plate 31. The annular protrusion 312 and the annular groove 322 cooperate to clamp the reflective film.

[0050] As described above, an annular protrusion 312 is provided at the outer ring of each first through hole 311, and an annular groove 322 matching the annular protrusion 312 is provided at the outer ring of each second through hole 321. When installing the film, cover the reflective film on the annular groove 322 or the annular protrusion 312, and gently press the first pressing plate 31 and the second pressing plate 32 so that the annular protrusion 312 can be embedded into the annular groove 322 while tightly clamping the reflective film. Further, the size of the reflective film should be large enough to ensure that it can cover the annular groove 322 or the annular protrusion 312.

[0051] Refer to Figure 5, in one embodiment, the second model component 2 includes a plurality of second molds 21. The second mold 21 includes a backing plate 211. A receiving portion 212 is formed by protruding towards the first model component 1 at the center of the backing plate 211. A receiving groove 213 for receiving the white embryo hemisphere is provided on the receiving portion 212.

[0052] As described above, the second model component 2 includes a plurality of second molds 21. Each second mold 21 is fixed to the bottom mold component 4 by screws or other fixed connection means. Each second mold 21 corresponds to a first through hole 311, a second through hole 321, and an installation portion 13. That is, when applying the film, each installation portion 13 corresponds to a first through hole 311, a second through hole 321, and a second mold 21. The center lines of the corresponding first through hole 311, second through hole 321, second mold 21, and installation portion 13 coincide with each other. Further, each second mold 21 can be set separately, or a plurality of second molds 21 can be assembled into a second model as a whole. The second mold 21 includes a backing plate 211. A receiving portion 212 is formed by protruding towards the first model component 1 at the center of the backing plate 211. A receiving groove 213 for receiving the white embryo hemisphere is provided on the receiving portion 212. Wherein, the diameter of the receiving groove 213 is equal to the sum of the diameter of the white embryo hemisphere and the thickness of the reflective film. The thickness of the second pressing plate 32 is the same as the protruding height of the protruding receiving portion 212 to ensure that the reflective film in the middle is flush with the upper plane of the receiving portion 212, that is, the notch of the receiving groove 213 is in the same plane as the second pressing plate 32.

[0053] It is worth mentioning that the receiving groove 213 can be in a cylindrical shape or a hemispherical shape adapted to the spherical surface of the white embryo hemisphere.

[0054] In addition, the backing plate 211 can be initially fixed to the bottom mold component 4 by 4 screws but not fully tightened. Therefore, when the first mold component presses down, there is a certain buffer space for movement between the lower backing plate 211 and the bottom mold component 4. By slowly pressing down, the second mold 21 can be automatically positioned and aligned. To make the positioning easier, lubricating oil can be added between the contact surfaces of the bottom mold component 4 and the backing plate 211.

[0055] In one embodiment, a guiding inclined surface 214 is provided at one end of the receiving groove 213 close to the first model component 1.

[0056] As described above, a guiding inclined surface 214 is provided at one end of the receiving groove 213 close to the first model component 1, that is, a guiding inclined surface 214 is provided at the opening of the receiving groove 213 to facilitate guiding the white embryo hemisphere into the receiving groove 213.

[0057] In one embodiment, a guide post 15 is provided at the center of the pressing plate 11 on the side facing the second mold assembly 2, and a guide groove 41 matching the guide post 15 is provided on the side of the bottom mold assembly 4 facing the first mold assembly 1.

[0058] As described above, a guide post 15 is provided at the center of the pressing plate 11 on the side facing the second mold assembly 2. The guide post 15 protrudes towards the bottom mold assembly 4, and the length of the guide post 15 should be greater than the total length after the blank hemisphere is installed in the installation part 13. A guide groove 41 matching the guide post 15 is provided on the side of the bottom mold assembly 4 facing the first mold assembly 1. Preferably, the center of the bottom mold assembly 4 also protrudes towards the first mold assembly 1, and the guide groove 41 is provided at the center of the protruding part. The shape of the guide groove 41 is the same as that of the guide post 15. The protruding height of the protruding part of the bottom mold assembly 4 should be equal to the overall thickness of the second mold 21 to jointly support the two pressing plates. Guide holes are also provided at the centers of the first pressing plate 31 and the second pressing plate 32. During pressing, the guide post 15 passes through the guide holes at the centers of the first pressing plate 31 and the second pressing plate 32 in sequence and then extends into the guide groove 41. During the entire pressing process, the guide post 15 will extend into the guide groove 41 before the blank hemisphere enters the receiving groove 213 to guide the blank hemisphere into the receiving groove 213 without displacement.

[0059] Refer to Figure 6 , in one embodiment, an installation groove 42 is provided on the side of the bottom mold assembly 4 away from the first mold assembly 1, and the installation groove 42 is used to install a thermocouple sheet.

[0060] As described above, an installation groove 42 for installing a thermocouple sheet is provided at the lower end of the bottom mold assembly 4. The thermocouple sheet can keep the bottom mold assembly 4 and the second mold 21 at a constant temperature of 80°. At this temperature, the reflective film has better stretching ductility.

[0061] In one embodiment, a locking structure 43 is provided on the bottom mold assembly 4, and the bottom mold assembly 4 is fixed to an external device through the locking structure 43.

[0062] As described above, a locking structure 43 is provided on the side edge of the bottom mold assembly 4. The locking structure 43 can specifically be a long strip-shaped chute structure. The bottom mold assembly 4 can be fixed to an external device through the cooperation of the locking structure 43 and a screw. The locking structure 43 can adjust the position of the bottom mold assembly 4 relative to the external device and has better adaptability.

[0063] Refer to Figure 7, in one embodiment, the driving device 5 includes a base 51, a fixing component 52, a support rod 53 and a driving component 54. The fixing component 52 is fixed on the base 51 and is used for fixing the bottom die component 4. The support rod 53 is installed on the base 51. The driving component 54 is installed on the support rod 53 and can move up and down relative to the support rod 53. A lifting device is arranged in the driving component 54. The first model component 1 is installed on the lifting device. Under the action of the lifting device, the first model component 1 abuts against the second model component 2 to achieve pressing.

[0064] As described above, the driving device 5 is a press, which includes a base 51, a fixing component 52, a support rod 53 and a driving component 54. A horizontal plane for placing the fixing component 52 is provided on the base 51. The support rod 53 is vertically arranged on the side edge of the base 51. The driving component 54 is installed on the support rod 53. A tension adjustment mechanism for adjusting and fixing the driving component 54 is provided at the top of the support rod 53. When it is necessary to adjust the position of the driving component 54 on the support rod 53, it can be achieved by adjusting the tension adjustment mechanism, so that the driving device 5 can be adapted to manufacturing devices of different specifications and sizes. A lifting device is arranged in the driving component 54. By adjusting the lifting device, the position of the first model component 1 relative to the second model component 2 can be controlled to achieve pressing and laminating and separating the first model component 1 from the second model component 2, which is convenient for the installation and unloading of the clamping component 3.

[0065] In one embodiment, the lifting device includes a rocker 541, a lifting rod 542 and an intermediate driving member 543. The intermediate driving member 543 is arranged in the driving component 54. The lifting rod 542 is arranged through the driving component 54. The first end of the intermediate driving member 543 is connected to the rocker 541, and the second end of the intermediate driving member 543 is connected to the lifting rod 542. The first model component 1 is installed on the lifting rod 542. Under the driving action of the rocker 541, the lifting rod 542 can move relative to the driving component 54, thereby driving the first model component 1 to move.

[0066] As described above, the lifting device includes a rocker 541, a lifting rod 542, and an intermediate driving member 543. A receiving space for receiving the intermediate driving member 543 is provided in the driving assembly 54. The intermediate driving member 543 is disposed in the receiving space. The intermediate driving member 543 is in transmission connection with the rocker 541 and is also in transmission connection with the lifting rod 542. The intermediate driving member 543 can be a transmission rod or a transmission gear. The specific connection manner between the intermediate driving member 543 and the rocker 541 and the lifting rod 542 is not limited. During operation, when the rocker 541 is pressed clockwise, the lifting rod 542 moves downward relative to the driving assembly 54. When the rocker 541 is pressed counterclockwise, the lifting rod 542 moves upward relative to the driving assembly 54, thereby realizing the movement of the first model assembly 1;

[0067] Further, limiting structures 544 are provided at both ends of the lifting rod 542. The limiting structures 544 are used to hold the lifting rod 542 in the driving assembly 54 to prevent it from detaching when the lifting rod 542 moves up and down relative to the driving assembly 54.

[0068] In one embodiment, the fixing assembly 52 includes a fixing base plate 521, fastening screws 522, and fastening nuts 523. A sliding groove 511 for installing the fastening screws 522 is provided on the base 51. The fastening screws 522 can move relative to the sliding groove 511. The large-head ends of the fastening screws 522 are installed in the sliding groove 511, and the small-head ends of the fastening screws 522 extend out of the sliding groove 511 and pass through the fixing base plate 521 and then are connected to the fastening nuts 523.

[0069] As described above, the sliding groove 511 is a trapezoidal groove with a large end and a small end. The width of the upper end of the sliding groove 511 is greater than the diameter of the small-head end of the fastening screw 522 and less than the diameter of the large-head end of the fastening screw 522 to limit the large-head end of the fastening screw 522 in the sliding groove 511. Through holes are provided in the fixing base plate 521. The small-head ends of the fastening screws 522 extend out of the sliding groove 511, pass through the through holes of the fixing base plate 521, and then are connected to the fastening nuts 523. Through holes corresponding to the fastening screws 522 are also provided on the bottom die assembly 4. When installing the bottom die assembly 4 on the base 51, the fastening nuts 523 are unscrewed, and the bottom die assembly 4 can be fixed to the base 51 through the cooperation of the through holes on the bottom die assembly 4 and the fastening screws 522. Then, the fastening nuts 523 are assembled to the fastening screws 522 to complete the fixation.

[0075] S5. Start the thermocouple chip and heat the bottom mold component 4 to a second preset temperature;

[0076] S6. Drive the lifting rod 542 to move so that the first model component 1 and the second model component 2 are pressed together for a preset time and then the pressing ends to obtain a semi-finished product of the film pasting;

[0077] S7. Cut off the excess reflective film in the semi-finished product of the film pasting to obtain a semi-finished product of the marking ball;

[0078] S8. Press two semi-finished products of the marking balls together to form a complete marking ball.

[0079] As described in step S1 above, before installing the first model component 1 on the lifting rod 542, a compression spring will be installed on each limit post 14 first and then the connecting part 12 will be installed and fixed to the lifting rod 542. The bottom mold component 4 is installed on the base 51. Among them, before this, the thermocouple chip can be installed in the installation groove 42 of the bottom mold component 4; install the second model component 2 on the bottom mold component 4. Among them, installing the first model component 1 on the lifting rod 542 and installing the bottom mold component 4 on the base 51 do not need to be in a specific order and can also be carried out simultaneously;

[0080] Further, after completing the above steps, the stroke of the lifting rod 542 can be adjusted to avoid an excessive or too small stroke of the lifting rod 542 during the pressing process, resulting in an unsatisfactory pressing effect;

[0081] As described in step S2 above, installing multiple white embryo hemispheres on the first model component 1 can be carried out before installing the first model component 1 on the lifting rod 542 or after installing the first model component 1 on the lifting rod 542;

[0082] As described in the above steps S3 - S4, a plurality of the reflective films are fixed on the clamping assembly 3 and glue is applied on the reflective films. That is, at the facing surfaces of the first pressing plate 31 or the second pressing plate 32, one reflective film is laid corresponding to each first through - hole 311 or second through - hole 321. Then, the first pressing plate 31 or the second pressing plate 32 is pressed tightly so that the reflective film is only clamped between the first pressing plate 31 or the second pressing plate 32. Then, hot - melt glue is applied on the side of all the reflective films that contacts the white embryo hemisphere, and the clamping assembly 3 is placed in a baking machine. After heating the reflective film and the glue to 100 °C, the clamping assembly 3 is installed on the bottom die assembly 4 so that the reflective film is located between the first model assembly 1 and the second model assembly;

[0083] As described in the above step S5, while performing steps S3 - S4, the thermocouple can be started to heat the bottom die assembly 4 to 80 °C. The thermocouple can keep the bottom die assembly 4 at a constant temperature of 80 °C, so that after the baked and heated clamping assembly 3 is installed on the bottom die assembly 4, it can still maintain a temperature of about 80 °C, making the reflective film have better stretching ductility for subsequent film pasting;

[0084] As described in the above step S5, the lifting rod 542 is driven to move so that the first model assembly 1 moves towards the second model assembly 2 for pressing. During this process, when the white embryo hemisphere contacts the reflective film and continues to move towards the second model assembly 2, it will finally extend into the receiving groove 213, making the reflective film completely fit the spherical surface of the white embryo hemisphere. The pressing is maintained for 2 minutes. After the glue is cured, the lifting rod 542 is driven to rise so that the white embryo hemisphere with the reflective film pasted is separated from the receiving groove 213, obtaining a semi - finished product of the labeled ball;

[0085] S7. Cut off the excess reflective film in the semi - finished product of the labeled ball to obtain a semi - finished product of the marked ball;

[0086] S8. Press the two semi - finished products of the marked balls to form a complete marked ball.

[0087] As described in the above steps S7 - S8, the semi - finished product of the labeled ball is taken off, and the excess reflective film corner materials in the semi - finished product of the labeled ball are cut off to obtain a semi - finished product of the marked ball. The two semi - finished products of the marked balls are pressed to form a complete marked ball.
