The transfer device 100 includes a base 10, a turntable mechanism 11, a heating mechanism 14, and a printing mechanism 18.

Wherein the heating mechanism 14 has a heating cavity, the turntable mechanism 11 is rotatable relative to the heating mechanism 14, and a part of the turntable mechanism 11 is located in the heating cavity, and the turntable mechanism 11 includes a mounting position 125 for arranging a member to be printed. The printing mechanism 18 is located at one side of the turntable mechanism 11, and the printing mechanism 18 is used for printing on the to-be-printed member installed on the installation position 125 of the turntable mechanism 11, so that the to-be-printed member is printed and heated, dried and shaped synchronously, thereby saving time and improving production efficiency.

In the embodiment, the turntable mechanism 11 is used for driving the to-be-printed piece to rotate, and in the rotating process, the printing and the heating are simultaneously carried out. In the present embodiment, the member to be printed is the connector 13, and the connector 13 is taken as an example to be described in detail below.

It is understood that in other embodiments, the member to be printed may be other products or structures, and is not limited in particular, and the member to be printed only serves as an environmental element.

Because the traditional printing and heating equipment needs to print characters on the same batch of connectors and then put the same into a dryer for heating, drying and shaping. The printing process and the drying and shaping process are carried out step by step, so that the operation time is longer, and the operators are in a waiting state during the heating and drying process, and the efficiency is low.

The transfer device 100 according to the present embodiment can achieve the purpose of heating while printing. When the connector 13 leaves the heating mechanism 14, the characters on the surface of the connector 13 are heated, dried and shaped, so that the working efficiency is greatly improved, and the working time is saved.

The specific structure and the correspondence relationship between the respective components of the transfer device 100 provided in the present embodiment will be described in detail below.

Fig. 2 is a schematic structural diagram of a second viewing angle of the transfer device 100 according to the present embodiment, and please refer to fig. 1 and fig. 2.

The heating mechanism 14 is fixedly disposed on the base 10, and the heating mechanism 14 and the base 10 form a heating chamber.

The turntable mechanism 11 is capable of rotating relative to the heating mechanism 14, and a part of the turntable mechanism 11 is located in a heating cavity of the heating mechanism 14, and a part of the turntable mechanism 11 is located outside the heating mechanism 14. The printing mechanism 18 is located at one side of the turntable mechanism 11, and the printing mechanism 18 is used for printing on a member to be printed which is mounted on the turntable mechanism 11. The turntable mechanism 11 intermittently rotates, firstly, the printing mechanism 18 moves in the vertical direction to print one of the mounting positions 125 on the turntable mechanism 11, then, the turntable mechanism 11 drives the mounting position 125 to rotate by a certain angle, and simultaneously, the printed piece to be printed is heated, and the printing mechanism 18 prints the connector 13 on the next mounting position 125, so that the purpose of printing and heating is achieved.

Further, the turntable mechanism 11 is rotatably disposed on the base 10 or the heating mechanism 14, and a portion of the turntable mechanism 11 is located in the heating chamber. The printing mechanism 18 is fixedly disposed on the base 10, and the printing mechanism 18 is located above the turntable mechanism 11.

In the present embodiment, the rotating disc mechanism 11 is rotatably disposed on the base 10, and it should be understood that, in other embodiments, the rotating disc mechanism 11 is rotatably disposed on the heating mechanism 14, and the specific connection structure is not limited as long as it is satisfied that the rotating disc mechanism 11 can be rotatably disposed in the heating cavity of the heating mechanism 14, which depends on the actual requirement.

Fig. 3 is a schematic structural view of the base 10 and the heating mechanism 14 after being fixed, and fig. 4 is a sectional view taken along a-a in fig. 3, as shown in fig. 3 and fig. 4.

The heating mechanism 14 comprises a dryer 15 and a heat insulation cover 16, the dryer 15 is fixedly connected with the heat insulation cover 16, and the dryer 15 is used as a heat source for blowing hot air into the heat insulation cover 16. Therefore, the dryer 15 is provided with an air outlet, the air outlet of the dryer 15 is positioned at one side close to the heat insulation cover 16, the heat insulation cover 16 is buckled with the base 10 to form a heating cavity, a ventilation hole is formed at one side of the heat insulation cover 16 close to the dryer 15, and the air outlet of the dryer 15 is communicated with the heating cavity through the ventilation hole.

One side of the heat insulation cover 16 is provided with a through hole 162, a turning hole 164 and a turning hole 166. The turning-in hole 164 and the turning-out hole 166 are respectively located at two ends of the through hole 162, and when the turntable mechanism 11 is installed, the through hole 162 is just matched with the turntable mechanism 11 to serve as a rotation passage. The rotary table mechanism 11 penetrates through the through hole 162, and the rotary hole 164 and the rotary hole 166 can be respectively matched with a piece to be printed of the rotary table mechanism 11.

In other words, the connector 13 is mounted on the mounting position 125 of the rotating disk mechanism 11, and the rotating disk mechanism 11 drives the connector 13 to rotate clockwise or counterclockwise, so that the connector 13 enters the heating cavity from the turning-in hole 164 and exits from the turning-out hole 166.

In this embodiment, the top of the thermal insulation cover 16 further defines a clearance hole 168, the clearance hole 168 is close to the rotation hole 164 relative to the rotation hole 166, and the clearance hole 168 corresponds to one of the mounting positions 125 on the rotating disc mechanism 11. The printing member 185 of the printing mechanism 18 is positioned just above the clearance hole 168, and the printing member 185 passes through the clearance hole 168 under the action of an external force to print the connector 13 positioned on the mounting position 125 corresponding to the clearance hole 168.

Further, the clearance holes 168 are circular holes, and the diameter of the clearance holes 168 is slightly larger than the printing member 185 of the printing mechanism 18, so that the printing operation is facilitated.

It is understood that the top of the heat-insulating cover 16 may be provided without the clearance holes 168, the printing mechanism 18 is provided on the base 10, and the printing member 185 of the printing mechanism 18 is positioned above the turntable mechanism 11 and outside the heat-insulating cover 16. In the process of rotating the rotary table mechanism 11, the printing mechanism 18 prints on the connector 13 on one of the mounting positions 125, then the connector 13 rotates with the rotary table mechanism 11 to the heating cavity of the heating mechanism 14, the printing mechanism 18 prints on the next connector 13, and the processes are circulated in sequence, and when the connector 13 on the first mounting position 125 rotates out from the heating cavity, the printing on the connector 13 is basically dried and shaped, so that the printing and drying and shaping processes are completed.

Further, the turntable mechanism 11 is rotatably arranged in the heating cavity, and a gap of 1-2mm is formed between the heat insulation cover 16 and the upper surface of the turntable mechanism 11, so that smooth rotation is facilitated.

Of course, when the top of the thermal insulation cover 16 is provided with the clearance hole 168, the clearance hole 168 may be other than circular, and is not limited as long as the printing member 185 of the printing mechanism 18 passes through the clearance hole 168 to print the connector 13 on the lower mounting position 125.

Fig. 5 is a schematic structural diagram of the turntable mechanism 11, please refer to fig. 5.

The turntable mechanism 11 includes at least two turntable bodies 12 and a driving member, each turntable body 12 is provided with a plurality of mounting positions 125 for mounting the connectors 13.

Each of the turntable bodies 12 is provided with a first positioning mark 127, wherein the mounting positions 125 on the turntable bodies 12 may be the same or different, and different turntable bodies 12 correspond to different connectors 13. And at least two second positioning marks 105 are arranged on the base 10 at intervals, and different second positioning marks 105 are corresponding to different turntable bodies 12 of the mounting positions 125.

When the turntable body 12 is replaceably disposed in the heating chamber, the first positioning mark 127 of the turntable body 12 can selectively correspond to one of the second positioning marks 105 on the base 10.

Since the sizes of the connectors 13 with different specifications are different, when the connectors 13 with different specifications are printed, the corresponding turntable main body 12 needs to be replaced. In the present embodiment, the size of the turntable body 12 is not changed, and only the size, the number and the distribution of the mounting locations 125 disposed on the turntable body 12 are changed, and the centers of all the mounting locations 125 on the same turntable body 12 are located on the same reference circle. The position of the reference circle of the mounting locations 125 on different dial bodies 12 is unchanged.

After replacing a different turntable body 12, it is necessary to align the first positioning mark 127 on the turntable body 12 with the corresponding second positioning mark 105 on the base 10, so that the projection of the printing member 185 of the printing mechanism 18 on the turntable body 12 coincides with one of the mounting positions 125. During operation, the rotating angle of the driving piece is changed, so that the connectors 13 with different specifications are printed.

The driving member provides power for the turntable body 12, and drives the turntable body 12 to move according to the rotating angle and speed.

Further, after the turntable body 12 and the heating mechanism 14 are connected, the heating mechanism 14 divides the turntable body 12 into a first area 121 and a second area 123. Wherein the first region 121 is located in the heating chamber and the second region 123 is located outside the heating mechanism 14. That is, the heating mechanism 14 can heat the connector 13 in the first area 121 to dry and set it, and the second area 123 is convenient for the operator to place or take the connector 13. During rotation of the turntable body 12, the same mounting location 125 is switched between the first region 121 and the second region 123.

In the embodiment, the turntable body 12 is a disc structure, and the turntable body 12 rotates around its own center under the driving of the driving member. The mounting locations 125 are circular grooves that open onto the turntable body 12.

Further, the mounting positions 125 are disposed in a region of the turntable body 12 near the outer edge, and centers of circles of all the mounting positions 125 are located on the same reference circle, so that the number of the mounting positions 125 is increased as much as possible in a certain area. The projection of the printing member 185 of the printing mechanism 18 on the turntable body 12 can coincide with one of the mounting positions 125, and the mounting positions 125 and the connectors 13 are provided with positioning marks, so that the connectors 13 are positioned on the mounting positions 125.

Further, the mounting locations 125 are provided in a plurality and are evenly spaced, and the size of the mounting locations 125 matches the size of the connector 13 and also matches the size of the printing members 185 of the printing mechanism 18.

Fig. 6 is a schematic structural diagram of the printing mechanism 18, and fig. 7 is an exploded schematic diagram of the printing mechanism 18, as shown in fig. 6 and 7.

The printing mechanism 18 includes a power unit 181, a housing 182, a lower carriage 183, a pad 184, and a printing unit 185. The housing 182 is elastically connected to the lower bracket 183, the lower bracket 183 is provided with a turnover rail 1832, the inkpad 184 is fixedly disposed on the top of the lower bracket 183 and has an inkpad surface facing the printing member 185, the printing member 185 is connected to the housing 182 and is disposed below the inkpad 184, and the printing member 185 is slidably disposed on the turnover rail 1832 by the housing 182.

Further, the elastic connection means that a spring is provided between the housing 182 and the top of the lower bracket 183, and the housing 182 and the lower bracket 183 are elastically connected by the spring. In other embodiments, the elastic connection may be in other manners, and is not limited to a spring.

In this embodiment, the power member 181 is a hydraulic device mounted above the housing 182, which drives the housing 182 in a vertically downward direction. When the housing 182 carries the printing member 185 to the lowest portion, the elastic member on the top of the lower bracket 183 is compressed, and at this time, the pressure of the hydraulic device is removed, and the housing 182 moves upward to be reset under the action of the elastic member.

The housing 182 drives the printing member 185 to move along the turning track 1832 of the lower frame 183, and during the movement, the printing member 185 and the lower frame 183 form a turning assembly, so that the printing member 185 can be automatically turned during the movement.

Specifically, the housing 182 and the lower bracket 183 are both cylindrical, and one side of the housing 182 facing the lower bracket 183 is provided with two support lugs for hinging with the printing member 185. The lower bracket 183 includes a top portion, a bottom portion and a connecting portion located between the top portion and the bottom portion, the connecting portion is provided with a turning rail 1832, the turning rail 1832 is disposed in a vertical direction, the pad 184 is fixedly disposed on the top portion of the lower bracket 183, a pad surface of the pad 184 faces the printing member 185, the printing member 185 is located between the bottom portion and the top portion of the lower bracket 183, and the printing member 185 moves along the turning rail 1832 of the lower bracket 183 under the action of the housing 182.

The printing member 185 has a printing surface, and the printing member 185 can be turned 180 ° during the up-and-down movement. In other words, the printing face is turned 180 ° toward the connector 13 on the turntable mechanism 11 while the printing member 185 moves downward; when the printing member 185 is moved upward to return, the printing surface is turned 180 ° again toward the pad surface of the pad 184. Thus, in one stroke, the printing member 185 first abuts the pad 184, then is turned 180 ° to print on the connector 13, and then is turned 180 ° to abut the pad 184 after printing is completed, thereby achieving automatic turning during the movement.

Further, the flipping track 1832 on the lower bracket 183 comprises a first straight line segment 1833, a flipping arc segment 1834 and a second straight line segment 1835 connected in sequence. The first straight line segment 1833 and the second straight line segment 1835 extend along a preset printing direction. The preset printing direction here refers to a direction in which the printing mechanism 18 moves to print toward the connector 13 on the turntable mechanism 11, and in the present embodiment, the preset printing direction is a vertical direction.

The turning arc-shaped segment 1834 is a semicircular structure, one side of the semicircle facing the horizontal direction is convex, a guiding column 1836 is convex arranged on the inner side wall of the connecting portion of the lower bracket 183, and the guiding column 1836 is located at the center of the turning arc-shaped segment 1834.

Corresponding to the lower frame 183, a guide bar 1852 and a guide groove 1854 are provided on the outer side wall of the printing member 185, and the guide bar 1852 is adjacent to the printing surface of the printing member 185 with respect to the guide groove 1854. The end of the guide 1854 near the guide bar 1852 is a closed end, and there is a space between the guide bar 1852 and the closed end of the guide 1854. When the guide posts 1836 slide to the closed end of the guide slot 1854, the distance between the guide posts 1836 and the guide bar is equal to the sum of the radius of the flip arc 1834 and the radius of the guide bar.

The guide bar 1852 is hinged to the lug of the housing 182 through the flipping rail 1832, and the guide column 1836 of the lower bracket 183 is slidably inserted into the guide groove 1854. When the guide posts 1836 slide to the closed end of the guide slot 1854, the printing member 185 and the lower carriage 183 cannot move up and down further, and the housing 182 continues to apply pressure to the printing member 185, at which time the guide posts 1836 rotate relatively at the closed end of the guide slot 1854, the guide bar 1852 of the printing member 185 moves along the flip arc 1834, thereby automatically flipping the printing member 185 180 °.

Further, both ends of the flip arc 1834 are in arc transition with the first and second

straight line segments

1833 and 1835, respectively.

The invention also provides a printing drying and shaping method, which comprises the step that the printing mechanism 18 dries the connector 13 while printing the connector, and the heating mechanism 14 dries the connector so as to dry and shape the printed connector 13. The printing and drying and shaping process of the transfer printing device 100 integrating printing and shaping provided by the embodiment of the invention is as follows:

the connectors 13 are sequentially arranged in the second area 123 of the turntable body 12, and the turntable body 12 intermittently rotates under the action of the driving piece. The mounting position 125 on which the first connector 13 is mounted is the first mounting position 125, and the turntable body 12 drives the first connector 13 to rotate, so that the turntable body 12 stops rotating after the central axis of the first mounting position 125 coincides with the central axis of the avoiding hole 168.

The printing member 185 of the printing mechanism 18 is positioned at the uppermost position and abuts against the pad surface of the pad 184, and the housing 182 is moved downward by the driving force 181. The printing member 185 is automatically turned 180 ° while passing through the turning arc 1834 of the lower carriage 183 and then continues to move downward until the printing member 185 abuts the connector 13, thereby oil-filming the connector 13.

The power member 181 moves the printing member 185 upward, and the printing member 185 is separated from the connector 13. The printing member 185 is automatically turned 180 ° as it passes over the turning arc 1834 of the lower carriage 183 and then continues to move upwardly, with the spring between the lower carriage 183 and the housing 182, as the housing 182 moves to the topmost position, the printing member 185 abuts the pad surface of the pad 184, thereby completing a pass of printing.

The turntable body 12 continues to rotate by a certain angle, so that the central axis of the second mounting position 125 where the second connector 13 is mounted coincides with the central axis of the avoiding hole 168, and the turntable body 12 stops rotating. At this time, the printed first connector 13 is heated, dried and set in the heating chamber of the heating mechanism 14. Repeating the above process, the printing mechanism 18 prints the connectors 13 one by one, and the heating mechanism 14 continuously heats the connectors 13 to make the connectors 13 have heating, drying and shaping for a certain time after printing, thereby realizing the function of heating, drying and shaping while printing. When the first connector 13 of the first mounting position 125 comes out of the heating cavity of the heating mechanism 14, the ink thereon has been dried and shaped, and the drying and shaping process is completed.
