[0035] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0036] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0037] like Figure 1-13 As shown, the present application provides a photosensitive pad 120 manufacturing device, including a pad fixing component 1 and a pad exposure component 2, the pad fixing component 1 includes a light receiving seat 110 and a photosensitive pad 120, the light receiving seat 110 is hollow inside to form a cylindrical placement space 113, the photosensitive pad 120 is roller-shaped and is arranged in the placement space 113, and the outer wall of the photosensitive pad 120 is tightly attached to the inner wall of the light receiving seat 110, and an exposure film 130 and a transfer paper 140 engraved with a pattern to be printed are also arranged between the light receiving seat 110 and the photosensitive pad 120; the pad exposure component 2 includes an upper shell 210 and a lower shell 220 A middle base 230 is provided between the upper shell 210 and the lower shell 220 for separation. An exposure module 240 is provided in the upper shell 210, and a control module 250 is provided in the lower shell 220. The exposure module 240 has an exposure space 241. The exposure module 240 is connected to the control module 250, and then the control module 250 can control the exposure module 240 to expose the exposure space 241. A cover plate 260 is also provided on the top of the upper shell 210. An exposure port 261 for inserting the printing pad fixing component 1 is opened on the cover plate 260, and the position of the exposure port 261 corresponds to the position of the exposure space 241. Based on the above structure, when the printing pad fixing component 1 cooperates with the printing pad exposure component 2, the light receiving seat 110 on the printing pad fixing component 1 is arranged in the exposure space 241 through the exposure port 261, and the exposure module 240 is arranged around the light receiving seat 110. The control module 250 can control the exposure module 240 to emit strong light, and the strong light is suitable for passing through the light receiving seat 110 to irradiate the transfer paper 140, the exposure film 130 and the photosensitive printing pad 120, so that the pattern on the transfer paper 140 is transferred to the photosensitive printing pad 120.

[0038] It is worth mentioning that the photosensitive pad 120 is supported by a photosensitive material. When the photosensitive material is exposed to strong light, it can absorb light energy and convert it into heat energy. The darker the color, the more energy it absorbs. When exposed, the light-exposed part of the photosensitive material surface absorbs a large amount of light energy instantly, and the temperature rises rapidly and reaches the melting point. After the flash ends, the temperature of the surface melt drops rapidly, forming a film of a certain thickness and strength. This film plays the role of sealing the pores and isolating the ink from penetrating. This embodiment uses the characteristics of the photosensitive material to make a seal. The transfer paper 140 clamped between the photosensitive printing pad 120 and the light receiving seat 110 includes an opaque area with a pattern to be printed and a translucent area without a pattern to be printed. The control module 250 controls the exposure module 240 to emit strong light to expose the photosensitive printing pad 120 in the exposure space 241. The strong light of the exposure module 240 passes through the light receiving seat 110 and shines on the transfer paper 140, the exposure film 130 and the photosensitive printing pad 120, and then the part of the photosensitive printing pad 120 corresponding to the translucent area of ​​the transfer paper 140 is illuminated by the strong light, and this part of the area melts to form a thin film that cannot leak oil. The part of the photosensitive printing pad 120 corresponding to the opaque area of ​​the transfer paper 140 is not illuminated by the strong light, and this part of the area remains as it is, forming a seal pattern.

[0039] Specifically, Figure 1-5 As shown, the light receiving seat 110 includes a light receiving top plate 111 and a light receiving glass tube 112. The light receiving glass tube 112 is arranged on one side of the light receiving top plate 111 close to the pad exposure assembly 2. The light receiving glass tube 112 and the light receiving top plate 111 define a placement space 113. A clamp unit 150 is arranged in the placement space 113. The clamp unit 150 is suitable for limiting the photosensitive pad 120 in the vertical axial direction and the horizontal radial direction, so as to fix the photosensitive pad 120 in the placement space 113 and make the outer side wall of the photosensitive pad 120 close to the inner side wall of the light receiving glass tube 112. The transfer paper 140 and the exposure film 130 are clamped between the photosensitive pad 120 and the light receiving glass tube 112 to avoid the relative position of the photosensitive pad 120 and the transfer paper 140 changing during the exposure and fixing process, resulting in overlapping and blurring of the pattern on the photosensitive pad 120.

[0040] Furthermore, the clamp unit 150 includes a positioning rod 151 arranged on the light-receiving top plate 111, and a fixed support plate 152, a movable support plate 153 and a supporting silicone pad 154 are arranged on the positioning rod 151. The fixed support plate 152 is fixedly connected to the positioning rod 151, and the movable support plate 153 is movably connected to the positioning rod 151. The supporting silicone pad 154 is sleeved on the positioning rod 151 and movably connected to the positioning rod 151, and the supporting silicone pad 154 is located between the fixed support plate 152 and the movable support plate 153, so that the movable support plate 153 can move in a direction close to the fixed support plate 152 to clamp the supporting silicone pad 154, and the photosensitive printing pad 120 is sleeved on the supporting silicone pad 154 and arranged in the placement space 113. The clamp unit 150 also includes a locking piece 155, which is suitable for limiting the movable support plate 153 so as to clamp the supporting silicone pad 154. Since the supporting silicone pad 154 is made of a flexible material, when the supporting silicone pad 154 is clamped, the outer diameter of the supporting silicone pad 154 will expand, and the supporting silicone pad 154 will exert a horizontal radial force on the photosensitive pad 120, pressing the photosensitive pad 120 tightly against the light-receiving glass tube 112, so that the transfer paper 140 and the exposure film 130 are clamped between the light-receiving glass tube 112 and the photosensitive pad 120, thereby preventing the transfer paper 140 and the exposure film 130 from moving relative to the photosensitive pad 120 during the exposure process.

[0041] In some preferred embodiments, a pushing table 156 is provided on the movable support plate 153, and a pushing groove 157 cooperating with the pushing table 156 is provided on the supporting silicone pad 154. The pushing table 156 has a first pushing inclined surface 1561, and the pushing groove 157 has a second pushing inclined surface 1571. When the locking member 155 limits the movable support plate 153 to drive the movable support plate 153 to clamp the supporting silicone pad 154, the pushing table 156 is embedded in the pushing groove 157. The first push slope 1561 presses against the second push slope 1571, so that the outer diameter of the supporting silicone pad 154 is further expanded. The supporting silicone pad 154 is suitable for applying a horizontal radial force to the photosensitive pad 120 mounted thereon. The supporting silicone pad 154 is suitable for pressing the photosensitive pad 120 onto the light-receiving glass tube 112. The outer wall of the photosensitive pad 120 fits tightly against the inner wall of the light-receiving glass tube 112, clamping the transfer paper 140 and the exposure film 130 therebetween.

[0042] The specific operation of the operator installing the photosensitive printing pad 120 in the placement space 113 is as follows:

[0043] First, the operator winds the transfer paper 140 and the exposure film 130 on the outer wall of the photosensitive pad 120; then, the photosensitive pad 120 together with the transfer paper 140 and the exposure film 130 are placed on the supporting silicone pad 154; then, the supporting silicone pad 154 is installed on the positioning rod 151 and placed in the placement space 113; finally, when the movable support plate 153 is installed on the positioning rod 151, the pushing table 156 is embedded in the pushing groove 157, and the locking member 155 is used to lock the movable support plate 153. After the installation is completed, in the vertical axis, the photosensitive pad 120 is limited by the fixed support plate 152 and the movable support plate 153; in the horizontal radial direction, the photosensitive pad 120 is limited by the supporting silicone pad 154 and the light-receiving glass tube 112, and the transfer paper 140 and the exposure film 130 are clamped between the photosensitive pad 120 and the light-receiving glass tube 112 to prevent the transfer paper 140 and the exposure film 130 from moving relative to the photosensitive pad 120 during the exposure process.

[0044] In different embodiments, the type of the locking member 155 is not limited and can be selected according to actual conditions. For example, the locking member 155 can be implemented as a butterfly nut 1551, which is threadedly connected to the positioning rod 151, and the butterfly nut 1551 can be rotated clockwise or counterclockwise to limit the movable support plate 153 or unlock the movable support plate 153. Specifically, when the photosensitive printing pad 120 is fixed in the placement space 113, the operator can rotate the butterfly nut 1551 to lock the movable support plate 153 so that the movable support plate 153 and the fixed support plate 152 clamp the support silicone pad 154; when the photosensitive printing pad 120 is to be removed from the placement space 113, the operator can rotate the butterfly nut 1551 to unlock the movable support plate 153. In addition to the butterfly nut 1551, the locking member 155 can also be implemented as an eccentric cam clamping rod 1552. The eccentric cam clamping rod 1552 can be operated to make the eccentric cam abut against or separate from the movable support plate 153. When the eccentric cam abuts against the movable support plate 153, the eccentric cam clamping rod 1552 locks the movable support plate 153, so that the movable support plate 153 and the fixed support plate 152 clamp the supporting silicone pad 154; when the eccentric cam separates from the movable support plate 153, the eccentric cam clamping rod 1552 unlocks the movable support plate 153, and the movable support plate 153 can be removed from the positioning rod 151, thereby removing the photosensitive printing pad 120 from the placement space 113.

[0045] In some embodiments, Figure 6 and Figure 8-9As shown, the exposure module 240 includes a lamp tube fixing frame 242 and an exposure lamp group. The lamp tube fixing frame 242 includes an upper fixing frame 2421 and a lower fixing frame 2422 which are arranged in parallel up and down. The upper fixing frame 2421 and the lower fixing frame 2422 are both in annular shape. A plurality of first connecting seats 2424 are arranged on a side of the upper fixing frame 2421 close to the lower fixing frame 2422. A plurality of second connecting seats 2425 are arranged on a side of the lower fixing frame 2422 close to the upper fixing frame 2421. The first connecting seats 2424 are arranged at intervals along the circumferential direction of the upper fixing frame 2421, and the second connecting seats 2425 are arranged at intervals along the circumferential direction of the fixing seat. The first connecting seats 2424 and the second connecting seats 2425 correspond to each other one by one. The exposure lamp group includes a plurality of long strips. The two ends of each exposure lamp tube 243 are respectively arranged in the first connecting seat 2424 and the second connecting seat 2425, so that each exposure lamp tube 243 is vertically arranged between the upper fixing frame 2421 and the lower fixing frame 2422, and arranged in a ring shape, thereby forming an exposure space 241 in each exposure lamp tube 243, and the control module 250 is electrically connected to each exposure lamp tube 243, and the control module 250 can control the exposure of the exposure lamp tube 243. When the printing pad fixing assembly 1 is inserted into the exposure space 241, each exposure lamp tube 243 can be arranged around the photosensitive printing pad 120, and each exposure lamp tube 243 can expose the photosensitive printing pad 120 at 360°, so that the photosensitive printing pad 120 and the light receiving glass tube 112 do not need to rotate during the exposure process.

[0046] In other embodiments, Figure 7 and Figure 10-11 As shown, the exposure module 240 includes a lamp tube fixing frame 242 and an exposure lamp group. The lamp tube fixing frame 242 includes an upper fixing frame 2421 and a lower fixing frame 2422 which are arranged in parallel up and down. The upper fixing frame 2421 and the lower fixing frame 2422 are both in annular shape. The upper fixing frame 2421 and the lower fixing frame 2422 are both in annular shape. A connecting fixture 2423 extending in a vertical direction is further connected between the upper fixing frame 2421 and the lower fixing frame 2422. The connecting fixture 2423 is provided with a first connecting seat 2424 and a second connecting seat 2425. The exposure lamp group includes a plurality of exposure lamp tubes 243 in annular shape. The two ends of the exposure lamp tubes 243 are respectively They are respectively arranged in the first connecting seat 2424 and the second connecting seat 2425, so that each exposure lamp tube 243 is arranged in parallel between the upper fixing frame 2421 and the lower fixing frame 2422, thereby forming an exposure space 241 in each ring-shaped exposure lamp tube 243, and the control module 250 is electrically connected to each exposure lamp tube 243. The control module 250 can control the exposure of the exposure lamp tube 243. When the printing pad fixing assembly 1 is inserted into the exposure space 241, each exposure lamp tube 243 can be arranged around the photosensitive printing pad 120 to perform 360° exposure on the photosensitive printing pad 120, so that the photosensitive printing pad 120 and the light receiving glass tube 112 do not need to rotate during the exposure process.

[0047] It is worth mentioning that a heat-insulating silicone pad 244 is also provided in the first connecting seat 2424 and the second connecting seat 2425. The heat-insulating silicone pad 244 has good heat-insulating properties and can effectively block heat transfer. The heat-insulating silicone pad 244 can prevent the heat generated by the exposure lamp 243 from being transferred outward through the upper fixing frame 2421 or the lower fixing frame 2422, thereby preventing other components in the printing pad exposure assembly 2 from being damaged due to excessive temperature.

[0048] The printing pad exposure assembly 2 also includes a reflector 270, which is in the shape of a hollow cylinder. The reflector 270 is sleeved on the outer side of the exposure lamp tube 243, so that the light diverging outward from the exposure lamp tube 243 can be reflected by the reflector 270. The light reflected by the reflector 270 can be emitted back into the exposure space 241 to illuminate the transfer paper 140, the exposure film 130 and the photosensitive printing pad 120, thereby ensuring the exposure effect of the photosensitive printing pad 120.

[0049] Furthermore, a cooling fan 280 is also provided in the exposure space 241. The cooling fan 280 is arranged at the bottom of the exposure space 241 and is electrically connected to the control module 250. The control module 250 can control the cooling fan 280 to rotate when the exposure module 240 is exposed to generate airflow to dissipate the heat of the exposure lamp group in the exposure module 240. Corresponding air outlets and air inlets are also provided on the upper shell 210 to cooperate with the cooling fan 280 to form a circulating airflow channel in the upper shell 210.
