[0043] Please also see Figure 4 and Figure 5 In a second aspect, the present invention provides a lottery punching device for intelligent reading and redemption of instant lottery tickets, comprising a cam drive mechanism 9 and a punching mechanism 20, wherein the cam drive mechanism 9 is the cam drive mechanism described in any one of the above.

[0044] In one embodiment, the punching mechanism includes a base body 21 and a tool body 22 arranged on the base body, the base body 21 and the second cam 92 have corresponding positions, and the tool body 22 and the first cam 93 have corresponding positions. When the driving spindle 91 rotates a first angle, the second cam 92 can push the base body and the lottery ticket 2 to abut against each other. When the driving spindle 91 continues to rotate a second angle, the base body 21 and the lottery ticket 2 abut against each other, and the first cam 93 pushes the tool body 22 to penetrate the lottery ticket 2.

[0045] The first cam 93 has a following arc surface 931 and a pressing arc surface 932 formed on its circumference, and a pressing surface 921 and a holding pressure surface 922 formed on its circumference. The driving spindle 91 is equipped with the first cam 93 in the middle and the second cams 92 on the two sides. When the lottery ticket 2 is placed under the punching mechanism, point C is the starting point, and the driving spindle 91 rotates clockwise:

[0046] The driving spindle 91 rotates 0-120° during:

[0047] The first cam 93 rotates from point C to point A (that is, 120°) to form a following arc surface 931. During this process, the outer diameter of the first cam 93 is always equal to that of the second cam 92.

[0048] The second cam 92: The outer diameter gradually increases during the process of rotating from point C to point A (reaching the maximum value at point A), and the gradually increasing outer portion of the second cam 92 gradually squeezes the base body 21, causing the base body 21 to descend (the outer distance of the second cam 92 in this process is the pressing distance).

[0049] The driving spindle 911 rotates 120°-240° during:

[0050] The first cam 93: during the process of rotating from point A to point B, the outer diameter gradually increases to form a pressing arc surface 932, and the first cam 93 begins to squeeze the tool body 22, causing it to descend to punch the lottery ticket 2;

[0051] The second cam 92 rotates from point A to point B with a constant outer diameter to form a pressing surface 921 , and the base body 21 is in continuous contact with the lottery ticket 2 .

[0052] The driving spindle 91 rotates 240°-360° during:

[0053] The first cam 93: the outer diameter gradually decreases during the process of rotating from point B to point C, and when reaching point C, the outer diameter is consistent with the outer diameter of the second cam 92, and the tool body 22 returns to the most original state;

[0054] The second cam 92: The outer diameter of the second cam 92 gradually decreases during the process of rotating from point B to point C. When reaching point C, it is at the lowest position, forming the pressure holding surface 922. The base body 21 returns to its most original state, and the lottery ticket 2 completes the prize redemption and punching and can be withdrawn.

[0055] It can be understood that there is no limitation on the number of arc surfaces of the first cam 93 and the second cam 92, as long as the second cam 92 can push the base body 21 to abut against the lottery ticket 2 when the driving spindle 91 rotates by a first angle, and when the driving spindle 91 continues to rotate by a second angle, the base body 21 and the lottery ticket 2 abut while the first cam 93 can push the tool body 22 to penetrate the lottery ticket 2.

[0056] For example, in one embodiment, the first angle and the second angle are both 120 degrees. When the driving spindle 91 rotates 120 degrees, the second cam 92 pushes the base body 21 to abut against the lottery ticket 2. When the driving spindle 91 continues to rotate 120 degrees, the base body 21 and the lottery ticket 2 abut against each other, and the first cam 93 pushes the tool body 22 to penetrate the lottery ticket 2.

[0057] In one embodiment, in order to better define the position of the lottery ticket 2 during the abutment between the base body 21 and the lottery ticket 2, so that the force on the surface of the lottery ticket 2 is evenly applied and the punching stability of the lottery ticket 2 is improved, two second cams 92 are set, and the first cam 93 is arranged between the two second cams 92.

[0058] In one embodiment, when the driving spindle 91 deviates from the second angle, in order to enable the tool body 22 to automatically reset and improve the convenience of punching the lottery ticket 2, the base body 21 includes a base 14, and the base 14 is provided with a mounting groove (not marked in the figure) for accommodating the tool body 22. The tool body 22 includes a tool head base 11 and a tool fixing part 12 arranged on the tool head base 11. The tool head base 11 is sleeved with a tool resetting part 13, and the opposite ends of the tool resetting part 13 are elastically abutted against the tool fixing part 12 and the groove wall of the mounting groove. A tool head 16 is provided on the end of the tool head base 11 away from the first cam 93.

[0059] It is understandable that the tool reset member 13 may be a spring or a tubular silicone product, as long as the tool reset member can be compressed and elastically restored.

[0060] Specifically, when the driving spindle 91 rotates to the second angle, the first cam 93 pushes the cutter head base 11 to move downward, and under the support of the cutter fixing member 12 and the mounting groove, the cutter reset member 13 is compressed, and the cutter head 16 penetrates the lottery ticket 2. When the driving spindle 91 deviates from the second angle, under the action of the elastic restoring force of the cutter reset member 13, the cutter body 22 can be automatically reset.

[0061] In one embodiment, in order to limit the moving distance of the cutter head 16 toward the lottery ticket 2, a limiting hole 141 is provided on the base, and a first through hole (not marked in the figure) is provided on the bottom wall of the mounting groove, and the cutter head base includes a first part 111, a second part 112 and a limiting member 113, the first part 111 is a part in contact with the first cam 93, the second part 112 is connected to the first part 111, the second part 112 is a part that is sleeved with the tool resetting member 13 and connected to the cutter head 16, and a limiting connection hole (not marked in the figure) is provided on the second part 112, one end of the limiting member 113 is fixedly connected to the hole wall of the limiting connection hole, the other end of the limiting member 113 extends into the limiting hole 141, and the cutter head 16 extends into the first through hole.

[0062] In one embodiment, in order to improve the connection stability between the cutter head 16 and the cutter head base 11 , the cutter head 16 is connected to the second portion 112 via a cutter head fixing member 17 .

[0063] Specifically, the tool head fixing part 17 is a bolt, and a threaded hole cooperating with the tool head fixing part 17 is formed at one end of the second part 112 away from the first part 111. The tool head fixing part 17 and the wall of the threaded hole are threadedly connected, so that the tool head 16 and the tool head base 11 are firmly connected.

[0064] It is understandable that in other embodiments, the cutter head fixing member 17 may also be fixedly connected to the second part 112 by means of snap-fitting, plug-in connection, etc.

[0065] In one embodiment, when the driving spindle 91 deviates from the second angle, in order to enable the base body 21 to automatically reset and improve the convenience of punching the lottery ticket 2, two first positioning grooves (not shown) are provided on the surface of the base 14 away from the cam driving mechanism 9, and a first positioning member 15 is provided in each of the first positioning grooves. Specifically, the two first positioning grooves correspond to the positions of the two second cams 92, respectively, and the first positioning member 15 can be a spring or a tubular silicone product. When the driving spindle 91 rotates to the first angle, the two second cams 92 push the base body to move downward, and the first positioning member is supported by the top wall of the first positioning groove, and the first positioning member is compressed and squeezes the lottery ticket 2. When the driving spindle 91 continues to rotate to the second angle, since there is no height difference between the two second cams 92, the base body 21 and the lottery ticket 2 are in contact, and the first cam 93 pushes the tool body 22 to penetrate the lottery ticket 2. When the driving spindle 91 deviates from the second angle, the base body 21 can automatically reset under the action of the elastic restoring force of the first positioning member 15.

[0066] In one embodiment, two second positioning members (not shown) are further provided on the surface of the base 14 away from the cam drive mechanism 9, and the two second positioning members are spaced between the two first positioning members 15. Specifically, two second positioning grooves are provided on the surface of the base away from the cam drive mechanism 9, and a second positioning member is provided in each of the second positioning grooves. It can be understood that the second positioning member can be a spring or a tubular silicone product, and the pressing portion is a block structure. For example, the fixed stroke of the base is 3 mm, and when the base body 21 and the lottery ticket 2 are in contact, there is a gap of about 1 mm between the base 14 and the horizontal plane, and the gap is the thickness range of the lottery ticket 2. The surface of the lottery ticket 2 can be pressed by the first positioning member 15. In addition, considering that the fixed stroke of the second positioning member is less than 1 mm, the two second positioning members can press the lottery ticket 2. The lottery ticket 2 can be pressed in all directions by the first pressing member 15 and the second pressing member.

[0067] In one embodiment, in order to facilitate the connection between the cam driving mechanism 9 and the punching mechanism 20, the punching mechanism further includes a transmission body 101, and the transmission body 101 includes three transmission members 10, one of which is disposed on the cutter head base 11, and the other two transmission members 10 are respectively disposed on the base, the setting position of the transmission member 10 on the cutter head base 11 corresponds to the setting position of the first cam 93, and the setting positions of the two transmission members 10 on the base 14 correspond to the setting positions of the two second cams 92. Specifically, one of the transmission members 10 is disposed on the first part of the cutter head base 11, and the other two transmission members 10 are respectively disposed on the surface of the base 14 adjacent to the second cam 92.

[0068] Specifically, in order to improve the connection efficiency between the cam driving mechanism 9 and the punching mechanism 20 and reduce the degree of wear when the cam driving mechanism 9 and the punching mechanism 20 are connected, the transmission member is a roller structure.

[0069] In one embodiment, the lottery punching device further includes a housing assembly 102 and a driving assembly, a detection assembly 3 and a scanning assembly 7 arranged on the housing assembly 102, the driving assembly includes a gear structure 4, a controller 5 and a driving member 6 connected to the controller, the gear structure connects the driving member 6 and the cam driving mechanism 9, the detection assembly 3 and the scanning assembly 7 are both connected to the controller 5, the detection assembly 3 is used to identify the position of the lottery ticket 2, and the scanning assembly 7 is used to identify the image of the lottery ticket 2. Specifically, the driving member 6 can be a motor, the gear structure 4 includes a driving wheel 41 and a driven wheel 42, the driving wheel 41 is connected to the output shaft of the motor, the driven wheel 42 is connected to the driving wheel 41 and the driving main shaft 91, the detection assembly 3 can be a contact sensor, and the scanning assembly 7 can be an image recognition sensor.

[0070] In one embodiment, the shell assembly 102 includes a shell 1 and a support structure 80 arranged on the shell, the support structure 80 includes a first support 8, a second support 18 and a waste paper collector 19, the first support 8 and the second support 18 are arranged in sequence from top to bottom along the axial direction of the shell, the chamber between the second support 18 and the first support 8 is an insertion chamber 81 for the lottery ticket 2 to extend into, the second support 18 is provided with a second through hole 181 connected to the first through hole, and the waste paper collector 19 is detachably connected to the second support 18.

[0071] Specifically, the waste paper collecting member 19 can be detachably connected to the bottom of the second bracket 18 by means of snap connection, plug connection, thread connection, etc. When the cutter head 16 extends into the second through hole 181 through the first through hole, the cutter head 16 penetrates the lottery ticket 2, and the debris on the surface of the cutter head 16 falls into the waste paper collecting member 19 due to gravity. When the cutter head 16 needs to be replaced, the cutter head fixing member 17 can be replaced by removing the waste paper collecting member 19, and the worn cutter head 16 can be conveniently removed. It can be understood that by replacing the cutter head 16 with different pattern holes, the hole shape can be diversified to increase interest.

[0072] In a third aspect, the present invention further provides a method for punching a lottery ticket punching device as described above, comprising the following steps:

[0073] S1, the lottery ticket 2 is in contact with the detection component 3, the position signal of the lottery ticket 2 identified by the detection component 3 is transmitted to the controller 5, the controller 5 drives the driving member 6 to operate, the driving member 6 drives the gear structure 4 to rotate, the gear structure 4 drives the cam driving mechanism 9 to rotate, when the driving main shaft 91 rotates by a first angle, the protruding part of the second cam 92 pushes the base body 21 to abut against the lottery ticket 2, so that the base body 21 can press and fix the lottery ticket 2 to prevent the lottery ticket 2 from moving, thereby making the scanning and reading of the lottery ticket 2 more stable (not affected by the shaking and movement of the lottery ticket 2);

[0074] S2, the scanning component 7 reads that the lottery ticket 2 is not a winner, the controller 5 drives the driving member 6 to operate, and the driving member 6 drives the gear structure 4 to rotate in the opposite direction, so that the base body 21 is reset;

[0075] Alternatively, the scanning component 7 identifies and reads that the lottery ticket 2 has won a prize, the gear structure 4 continues to drive the cam drive mechanism 9 to rotate, and when the drive spindle 91 continues to rotate by a second angle, the base body 21 abuts against the lottery ticket 2, and the protruding portion of the first cam 93 pushes the tool body 22 to penetrate the lottery ticket 2, thereby realizing the function of redeeming the lottery ticket 2 and punching a hole;

[0076] After the tool body 22 penetrates the lottery ticket 2, the gear structure 4 continues to drive the cam drive mechanism 9 to rotate, the drive spindle 91 continues to rotate by a third angle, the base body 21 is reset, and the lottery ticket 2 completes the prize redemption punching and can be withdrawn.

[0077] For example, in one embodiment, the first angle, the second angle, and the third angle are all 120 degrees.
