Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] As Figures 1 to 11 shown, this surface font printing device for medical wire harnesses of the present invention includes a pressure - applying member 1, a mounting assembly 2, a printing member 3, and a bearing member 4. The mounting assembly 2 is arranged at the lower end of the pressure - applying member 1, the printing member 3 is installed at the lower end of the mounting assembly 2, and the bearing member 4 is located at the lower end of the printing member 3. By pushing the pressure - applying member 1 through a cylinder (not shown in the figure), the pressure - applying member 1 drives the mounting assembly 2 and the printing member 3 to move downward, so as to perform surface document printing on the medical wire harness 5 placed on the bearing member 4.

[0037] During printing, it is necessary to ensure that the medical wire harness 5 just comes out of the injection molding machine and has been cooled by cooling water, so that it has a certain shape and the surface temperature is still relatively high, maintaining a relatively soft state, which is convenient for the printing member 3 to apply pressure to its surface to generate text. Concave printing or convex printing can be adopted.

[0038] A cylinder is provided at the upper end of the pressure - applying member 1, and the cylinder drives the pressure - applying member 1 to move up and down. A fixing arm 6 is provided at the lower end of the pressure - applying member 1. A fixing area 7 is formed between the fixing arm 6 and the pressure - applying member 1, and the mounting assembly 2 is arranged in the fixing area 7. And fastening screws 8 are provided on both sides of the pressure - applying member 1 to fix the mounting assembly 2 in the fixing area 7 at multiple positions.

[0039] The mounting assembly 2 is arranged at the lower end of the pressing member 1. There are multiple mounting assemblies 2, and the mounting assemblies 2 are connected by a connecting rod 9. Nuts 10 are provided at both ends of the connecting rod 9. A through hole 11 for mounting the connecting rod 9 is provided on the mounting part 58.

[0040] The printing member 3 is arranged at the lower end of the mounting assembly 2, and the pressing member 1 and the mounting assembly 2 are driven by a cylinder to move up and down together. The printing member 3 is composed of a printing body 12, a connecting body 13, a limiting body 14, and a cylinder 15. The cylinder 15 and the limiting body 14 are installed in the limiting area 17, and the connecting body 13 is arranged in the clamping gap 16.

[0041] The bearing member 4 is arranged at the lower end of the printing member 3. The bearing member 4 is used to support the medical wire harness 5 and bear the pressure from the printing member 3. A groove 18 for accommodating the medical wire harness 5 is provided on the bearing member 4, and the groove 18 has a structure with a larger upper part and a smaller lower part.

[0042] There are two symmetrically arranged support bodies 19 on the bearing member 4. An activity area 20 is formed between the support bodies 19, and the lower end of the activity area 20 forms the groove 18. A rubber member 21 is provided on the support body 19. The rubber member 21 deforms under force, which can enable the cylinder to push the mounting assembly 2 and the printing member 3 to move downward, so as to print words on the surface of the medical wire harness 5 in the groove 18. Although the rubber member 21 can be compressed, it can limit the further downward movement of the mounting assembly 2, thereby limiting the printing depth of the printing member 3.

[0043] The mounting assembly 2 is arranged at the lower end of the pressing member 1 and moves up and down together with the pressing member 1. A cover plate 22 and a mounting body 23 are provided in the mounting assembly 2. The middle of the mounting body 23 is hollowed out and the lower end is open to form a sliding chamber 25. A sliding member 26, a limiting member 27, an elastic member 28, and symmetrically arranged holding members 29 are provided in the sliding chamber 25. The holding members 29 are installed on the cover plate 22 through a hinge shaft 30. A reciprocating groove 31 is provided on the sliding member 26. One end of the limiting member 27 is installed in the sliding chamber 25, and the other end is arranged in the reciprocating groove 31. One end of the elastic member 28 contacts the inner wall of the sliding chamber 25, and the other end contacts the sliding member 26. A limiting area 17 is formed between the symmetrically arranged holding members 29, and the printing member 3 is arranged in the limiting area 17.

[0044] A fixing part 24 cooperating with the fixing area 7 is provided on the mounting body 23. The fixing part 24 is arranged in the fixing area 7 and then fixed by a fastening screw 8. Since multiple mounting assemblies 2 are connected by a connecting rod 9, only two fastening screws 8 are needed.

[0045] The slider 26 is composed of a plate body 32 and a frame body 33. The reciprocating groove 31 is arranged on the plate body 32, and the frame body 33 is used to limit the position of the slider 26. And a blocking portion 34 is provided on the frame body 33, a positioning rod 35 is provided on the blocking portion 34, the elastic member 28 is arranged on the positioning rod 35, and one end is in contact with the blocking portion 34 and the other end is in contact with the inner wall of the sliding chamber 25.

[0046] A limiting block 36 cooperating with the limiting area 17 is arranged on the plate body 32. The limiting block 36 is provided with a first arc surface 37 and a second arc surface 38. The first arc surface 37 cooperates with the cylinder 15, and the second arc surface 38 cooperates with the hinge end 39.

[0047] The limiting member 27 is composed of a fixed end 40, a rod body 41 and a movable end 42. A fixed block 43 is arranged in the sliding chamber 25, and a fixing hole 44 for cooperating with the fixed end 40 is arranged in the middle of the fixed block 43. When the limiting member 27 is not installed, the fixed end 40 is inclined downward in the direction of the movable end 42, and the rod body 41 is inclined. Due to the inconsistent depth in the reciprocating groove 31, when the movable end 42 is placed in the reciprocating groove 31, the rod body 41 will be compressed or reset under its own elastic force, and the rod body 41 is kept switching between the horizontal state and the inclined state.

[0048] When the movable end 42 is in the first guiding section 45, the third guiding section 46 and the fifth guiding section 47, the rod body 41 is in the natural state at this time and the rod body 41 is inclined. When the movable end 42 is in the second guiding section 48, the fourth guiding section 49 and the sixth guiding section 50, the rod body 41 is lifted by the second guiding section 48, the fourth guiding section 49 and the sixth guiding section 50 at this time, so that the rod body 41 is in the horizontal state.

[0049] A stop block 51 is arranged in the sliding chamber 25, and a moving gap 52 is formed between the stop block 51 and the slider 26 for blocking the sliding distance of the slider 26.

[0050] The holding member 29 is composed of a hinge end 39 and a clamping end 53. The hinge end 39 is installed on the hinge shaft 30, and a clamping gap 16 is formed between the clamping ends 53.

[0051] A guiding block 54 is arranged on the holding member 29. A vertical groove 55 and an arc groove 56 are arranged on the mounting body 23. The vertical groove 55 and the arc groove 56 are communicated. The vertical groove 55 and the arc groove 56 are communicated with the sliding chamber 25, and the guiding block 54 cooperates with the vertical groove 55 and the arc groove 56. A guiding rod 57 is arranged on the guiding block 54. An installation portion 58 is arranged on the mounting body 23, a guiding hole 59 is arranged on the installation portion 58, and the guiding rod 57 is installed in the guiding hole 59. The shape of the guiding hole 59 cooperates with the vertical groove 55 and the arc groove 56.

[0052] Through the cooperation of the vertical groove 55, the arc groove 56 and the guiding hole 59, the holding member 29 can be opened under the push of the sliding member 26 and then rotated, so that the limiting area 17 and the clamping gap 16 are enlarged, facilitating the installation of the printed matter 3.

[0053] The reciprocating groove 31 is composed of a first guiding groove 60, a second guiding groove 61 and a third guiding groove 62. One end of the first guiding groove 60 is connected to one end of the second guiding groove 61, the other end of the second guiding groove 61 is connected to one end of the third guiding groove 62, and the other end of the third guiding groove 62 is connected to the other end of the first guiding groove 60, forming a structure with end-to-end connection.

[0054] A first positioning port 63 is formed at the connection of the first guiding groove 60 and the third guiding groove 62. The first positioning port 63 is used to limit the elastic force of the elastic member 28, so that the elastic member 28 is in a compressed state and stores elastic potential energy.

[0055] The first guiding groove 60 is composed of a first guiding section 45 and a second guiding section 48, the second guiding groove 61 is composed of a third guiding section 46 and a fourth guiding section 49, and the third guiding groove 62 is composed of a fifth guiding section 47 and a sixth guiding section 50. The first guiding section 45 and the second guiding section 48 are connected by a first transition section 64, the third guiding section 46 and the fourth guiding section 49 are connected by a second transition section 65, and the fifth guiding section 47 and the sixth guiding section 50 are connected by a third transition section 66. The depths of the first guiding section 45, the third guiding section 46 and the fifth guiding section 47 are H1, and the depths of the second guiding section 48, the fourth guiding section 49 and the sixth guiding section 50 are H2, and H1 > H2.

[0056] Due to H1 > H2, the movable end 42 of the limiting member 27 can only enter the second guiding groove 61 along the first guiding groove 60 of the reciprocating groove 31, enter the third guiding groove 62 from the second guiding groove 61, and then enter the first guiding groove 60 again from the third guiding groove 62.

[0057] A guiding protrusion 67 is also provided at the second guiding groove 61. The guiding protrusion 67 can guide the movable end 42 in the second positioning port 68 to the connection of the second guiding groove 61 and the third guiding groove 62. Due to the height difference, the movable end 42 will not move in the reverse direction.

[0058] A second positioning port 68 is formed in the fourth guiding section 49. The second positioning port 68 is also used to limit the elastic force of the elastic member 28, so that the elastic member 28 is in a compressed state. When the limiting member 27 is in the first positioning port 63, the compression length of the elastic member 28 at this time is L1. When the limiting member 27 is in the second positioning port 68, the compression length of the elastic member 28 is L2, and L1 > L2. When the limiting member 27 is in the second positioning port 68, the elastic potential energy of the elastic member 28 is larger. When the limiting member 27 is in the first positioning port 63, the elastic potential energy of the elastic member 28 is smaller. The elastic member 28 is a spring.

[0059] When installing the printed part 3, the movable end 42 is in the first positioning port 63. The elastic member 28 pushes the sliding member 26, so that the holding member 29 moves along the guiding hole 59, rotates and opens. Then the printed part 3 is placed between the symmetrically arranged holding members 29. Then, the limiting block 36 is pushed upward to compress the elastic member 28, so that the movable end 42 in the first positioning port 63 enters the first guiding groove 60. Then, when the external force is cancelled, the movable end 42 is kept in the third guiding section 46 and enters the second positioning port 68 in the fourth guiding section 49 under the guidance of the third guiding section 46 for positioning.

[0060] When replacement is needed, only the printed part 3 needs to be pushed upward again, so that the elastic member 28 is compressed, and the movable end 42 in the second positioning port 68 enters the fifth guiding section 47. Then, under the push of the elastic member 28, the movable end 42 enters the first positioning port 63.

[0061] It can be replaced quickly, which is convenient for quickly replacing the individual characters that need to be replaced, improves efficiency, saves time at the same time, and reduces the difficulty of manufacturing characters.

[0062] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
