[0018] 2. The utility model arranges an oil cup on the etching plate. The oil cup moves on the etching plate to apply ink on the etching plate and scrape off the excess ink. It can be understood that the oil cup contains ink, and the ink in the oil cup contacts the surface of the etching plate through the bottom of the oil cup. When the oil cup moves on the etching plate, the ink contacts the surface of the etching plate at the bottom of the oil cup, and the scraping strip at the bottom edge of the oil cup can scrape off the ink on the surface of the etching plate when the oil cup moves. When the oil cup passes through the etching area of the etching plate, the ink flows into the etching recesses in the etching area, so that the scraping strip of the oil cup does not scrape off the ink in the etching recesses, thus completing the attachment of the ink on the etching plate.

At the same time, by arranging two first magnetic members, the adsorption force of the first magnetic members on the pressing plate is more balanced, so that the pressure of the pressing plate on the oil cup is more balanced. Moreover, by arranging the two first magnetic members on both sides of the etching plate and the first magnetic members being parallel to the moving direction of the oil cup, the two first magnetic members can be far away from the upper part of the etching plate, thus avoiding adsorbing the first magnetic members on the etching plate. On the one hand, it avoids the first magnetic members adsorbing and deforming the etching plate. On the other hand, it enables the first magnetic members to avoid the etching plate and prevents the first magnetic members from adsorbing and taking away the ink containing metal powder.

[0024] 2. The utility model sets an oil cup on the etching plate. The oil cup moves on the etching plate to apply ink on the etching plate and scrape off the excess ink. It can be understood that the oil cup contains ink, and the ink in the oil cup contacts the surface of the etching plate through the bottom of the oil cup. When the oil cup moves on the etching plate, the ink contacts the surface of the etching plate at the bottom of the oil cup, and the scraping strip at the bottom edge of the oil cup can scrape off the ink on the surface of the etching plate when the oil cup moves. When the oil cup passes through the etching area of the etching plate, the ink flows into the etching recesses in the etching area, so that the scraping strip of the oil cup does not scrape off the ink in the etching recesses. Thus, the attachment of the ink on the etching plate is completed.

[0025] 3. The utility model sets a pressing plate, and the pressing plate is used to press the oil cup towards the etching plate, thereby making the seal between the oil cup and the etching plate better.

[0026] 4. The utility model sets two first magnetic members, which are respectively located on both sides of the etching plate. The first magnetic members are parallel to the moving direction of the oil cup. The two first magnetic members are arranged on one of the fixed platform and the pressing plate, and the two first magnetic members are magnetically adsorbed to the other of the fixed platform and the pressing plate so that the pressing plate presses the oil cup tightly against the etching plate. It can be understood that by adsorbing the pressing plate and the fixed platform through the first magnetic members, the pressure of the pressing plate on the oil cup is greater, thereby further improving the sealing performance between the oil cup and the etching plate. At the same time, by setting two first magnetic members, the adsorption force of the first magnetic members on the pressing plate is more balanced, so that the pressure of the pressing plate on the oil cup is more balanced. Moreover, by arranging the two first magnetic members on both sides of the etching plate and the first magnetic members being parallel to the moving direction of the oil cup, the two first magnetic members can be far away from the upper part of the etching plate. Furthermore, it is not necessary to adsorb the first magnetic members on the etching plate. On the one hand, it avoids the first magnetic members adsorbing and deforming the etching plate.

[0039] The following describes a pad printing cup printing platform device and a pad printer according to an embodiment of the present utility model with reference to the accompanying drawings.

[0040] Refer to Figure 1 , the present utility model aims to provide an embodiment of a pad printing cup printing platform device and a pad printer.

[0041] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , in this embodiment, a pad printer includes a pad printing cup printing platform device.

[0042] A pad printing cup printing platform device according to an embodiment of the present utility model includes a frame 100, a pad printing cup 130, a pressing plate 140 and two first magnetic members 150.

[0043] For the frame 100, a fixed platform 110 is provided on the frame 100, and an etched plate 120 is installed on the fixed platform 110, so that the etched plate 120 can be stably fixed on the fixed platform 110.

[0044] For the pad printing cup 130, the pad printing cup 130 is arranged on the etched plate 120 and moves on the etched plate 120 to apply ink on the etched plate 120 and scrape off the excess ink.

[0045] It can be understood that the pad printing cup 130 contains ink, and the ink in the pad printing cup 130 contacts the surface of the etched plate 120 through the bottom of the pad printing cup 130. When the pad printing cup 130 moves on the etched plate 120, the ink contacts the surface of the etched plate 120 at the bottom of the pad printing cup 130, and the scraping bar at the bottom edge of the pad printing cup 130 can scrape off the ink on the surface of the etched plate 120 when the pad printing cup 130 moves. When the pad printing cup 130 passes through the etched area of the etched plate 120, the ink flows into the etched recesses in the etched area, so that the scraping bar of the pad printing cup 130 does not scrape off the ink in the etched recesses, thus completing the attachment of the ink on the etched plate 120.

[0046] For the pressing plate 140, the pressing plate 140 is used to press the pad printing cup 130 against the etched plate 120, so that the seal between the pad printing cup 130 and the etched plate 120 is better.

[0047] In some specific embodiments, the pressing plate 140 has a first through hole 170 penetrating up and down. The first through hole 170 accommodates the oil cup 130. The outer side surface of the bottom of the oil cup 130 has a first convex edge 180. The bottom of the pressing plate 140 has a first sunk platform 190. The first sunk platform 190 accommodates the first convex edge 180. The first sunk platform 190 abuts against the first convex edge 180 to press the oil cup 130 towards the etching plate 120. Thus, it is convenient for the first through hole 170 to limit the oil cup 130 in the horizontal direction, making the position of the oil cup 130 accurate. At the same time, the first sunk platform 190 can abut against the first convex edge 180. When the pressing plate 140 is pressed down, the first sunk platform 190 abuts against the first convex edge 180 to drive the oil cup 130 to press down.

[0048] In some specific embodiments, a driving mechanism is provided on the frame 100. The driving mechanism is used to drive the pressing plate 140 to move so that the pressing plate 140 drives the oil cup 130 to move. The driving mechanism includes a translation seat 200 slidably arranged on the frame 100, a first power member 210 driving the translation seat 200 to translate, and a connection assembly 220 arranged on the translation seat 200. The connection assembly 220 is used to connect the pressing plate 140. Thus, the driving mechanism can automatically drive the oil cup 130 to move, improving the efficiency.

[0049] Further, the connection assembly 220 includes two connection arms 230. The connection arms 230 are provided with limit pins 240. The pressing plate 140 is provided with limit slots 250. The limit slots 250 cooperate with the limit pins 240 for limiting. Thus, through the cooperation of the limit pins 240 and the limit slots 250, the connection arms 230 can be linked with the pressing plate 140. Furthermore, it is convenient for the connection arms 230 to drive the pressing plate 140 to move.

[0050] In some specific embodiments, the translation seat 200 is located on one side of the oil cup 130. The two connection arms 230 are respectively located on both sides of the pressing plate 140 along the moving direction of the oil cup 130. Thus, the translation seat 200 and the connection arms 230 can avoid the upper part of the oil cup 130, preventing the translation seat 200 and the connection arms 230 from blocking the ink filling port at the top of the oil cup 130.

[0051] In some specific embodiments, the connection assembly 220 further includes a lifting seat 260. The lifting seat 260 is slidably arranged up and down on the translation seat 200. The two connection arms 230 are arranged on the lifting seat 260. The top of the limit slot 250 is open. The lifting seat 260 moves up and down to drive the limit pins 240 of the connection arms 230 to enter or disengage from the limit slots 250.

[0052] It can be understood that by lifting the lifting seat 260, the lifting seat 260 can drive the connecting arm 230 to rise, so that the limit pin 240 on the connecting arm 230 can be disengaged from the top of the limit groove 250, thereby facilitating the quick disconnection of the driving mechanism from the pressing plate 140, and further facilitating the replacement of the etching plate 120 and the oil cup 130.

[0053] Referring to Figure 5 , for the first magnetic members 150, the two first magnetic members 150 are respectively located on both sides of the etching plate 120. The first magnetic members 150 are parallel to the moving direction of the oil cup 130. The two first magnetic members 150 are arranged on one of the fixed platform 110 and the pressing plate 140, and the two first magnetic members 150 are magnetically adsorbed to the other of the fixed platform 110 and the pressing plate 140 so that the pressing plate 140 presses the oil cup 130 against the etching plate 120.

[0054] It can be understood that by adsorbing the pressing plate 140 to the fixed platform 110 through the first magnetic members 150, the pressure of the pressing plate 140 on the oil cup 130 is greater, thereby further improving the sealing performance between the oil cup 130 and the etching plate 120. At the same time, by arranging two first magnetic members 150, the adsorption force of the first magnetic members 150 on the pressing plate 140 is more balanced, so that the pressure of the pressing plate 140 on the oil cup 130 is more balanced. Moreover, by arranging the two first magnetic members 150 on both sides of the etching plate 120 and the first magnetic members 150 being parallel to the moving direction of the oil cup 130, the two first magnetic members 150 can be far away from the upper part of the etching plate 120, thereby avoiding adsorbing the first magnetic members 150 on the etching plate 120. On the one hand, it avoids the first magnetic members 150 adsorbing and deforming the etching plate 120. On the other hand, it enables the first magnetic members 150 to avoid the etching plate 120 and prevents the first magnetic members 150 from adsorbing and taking away the ink containing metal powder.

[0055] In some specific embodiments, the first magnetic member 150 is set as a magnetic strip, and the length direction of the first magnetic member 150 is parallel to the moving direction of the oil cup 130, so that the first magnetic member 150 can be continuously distributed in the path of the moving direction of the oil cup 130, and further, the magnetic force of the first magnetic member 150 in the moving path of the oil cup 130 is uniform and uninterrupted, avoiding the magnetic force of the first magnetic member 150 being intermittent and uneven in the moving path of the oil cup 130, which may cause the movement of the oil cup 130 to be stuck.

[0056] In some specific embodiments, two first magnetic members 150 are arranged on the fixed platform 110. The pressing plate 140 is provided with two second magnetic members 160, and the two second magnetic members 160 are magnetically adsorbed to the two first magnetic members 150 respectively. Thus, the fixed platform 110 and the pressing plate 140 can be magnetically adsorbed through the cooperation of the first magnetic members 150 and the second magnetic members 160. Furthermore, the adsorption force between the fixed platform 110 and the pressing plate 140 is stronger, further enhancing the pressure of the pressing plate 140 on the oil cup 130 and improving the sealing performance between the oil cup 130 and the etching plate 120.

[0057] Furthermore, the second magnetic member 160 is arranged as a magnetic strip, and the length direction of the second magnetic member 160 is parallel to the moving direction of the oil cup 130. Thus, the second magnetic member 160 can be continuously distributed on the pressing plate 140 along the moving direction of the oil cup 130. Furthermore, the magnetic force of the second magnetic member 160 on the first magnetic member 150 is uniform and uninterrupted during the moving distance of the oil cup 130, avoiding the magnetic force of the second magnetic member 160 on the first magnetic member 150 being intermittent and non-uniform during the moving process of the oil cup 130, which may cause the oil cup 130 to move stuck.

[0058] In some specific embodiments, the top surface of the first magnetic member 150 is used to support the second magnetic member 160, and the height of the top surface of the first magnetic member 150 is 3 mm - 5 mm higher than the height of the top surface of the etching plate 120. Thus, the height distance between the second magnetic member 160 and the etching plate 120 is increased, avoiding the second magnetic member 160 adsorbing the etching plate 120.

[0059] In the description of this specification, the description with reference to terms such as "one embodiment, some embodiments, illustrative embodiments, examples, specific examples or some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention.

Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0060] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field to which the present invention pertains, various changes can be made without departing from the purpose of the present invention.
