Description

Technical Field

[0001] The present invention relates to the field of printing, in particular to an automatic printing machine. Background Art

[0002] The surface of the circuit board is equipped with some electrical components, such as chip resistors. When manufacturing, it is often necessary to cover the substrate with an insulating glue layer, which is often called "green oil". The green oil on the surface of the circuit board is used as a solder mask. The solder mask is applied on the surface of the circuit board to protect the circuits on the board from short circuits by foreign objects as much as possible. When applying green oil, a printer is often used to print it on the circuit board. The printer can make the green oil evenly and firmly coated on the circuit board. Therefore, the method of using a printer to print the coating is favored by circuit board manufacturers.

[0003] When printing coatings, existing printers often need to manually place the printed substrate on the printing station for printing, and manually remove it after printing. Inaccurate manual loading position can easily cause inaccurate printing position, and manual unloading can easily damage the printed coating, resulting in low yield of printed products and a large waste of manpower and material resources. At the same time, the efficiency of manual loading and unloading is low, which cannot meet the high-efficiency and fast-paced processing of modern industrial manufacturing. Summary of the invention

[0045] Example 1

[0046] like Figure 1 As shown, this embodiment provides an automatic printing machine 1, including a printing mechanism 11, a transmission mechanism 12, a front material storage mechanism 13 and a rear material storage mechanism 14. The printing mechanism 11 includes a printing table 111, and a printing through slot 1111 is provided on the printing table 111. The transmission mechanism 12 is arranged under the printing table 111, and the front material storage mechanism 13 and the rear material storage mechanism 14 are arranged at both ends of the transmission mechanism 12. The transmission mechanism 12 can transmit the printed substrate between the front material storage mechanism 13 and the printing mechanism 11, and between the printing mechanism 11 and the rear material storage mechanism 14. The transmission mechanism 12 can also push the printed substrate into the printing through slot 1111 and has a retraction stroke.

[0047] Please also read Figure 2 then Figure 3 The printing mechanism 11 is a functional mechanism of the printing machine, and is used to print the printed substrate. The printing mechanism 11 includes a printing table 111 and a printing head 112. The printing table 111 is provided with a printing slot 1111, and the shape of the printing slot 1111 matches the shape of the printed substrate. The printed substrate is transferred to the printing slot 1111 by the transmission mechanism 12. After the printed substrate is printed by the printing head 112, the printed printed substrate is transferred out by the transmission mechanism 12.

[0048] The front storage mechanism 13 is used to store the printed circuit boards before printing, and the rear storage mechanism 14 is used to store the printed circuit boards after printing. The transmission mechanism 12 is used to transfer the printed circuit boards on the front storage mechanism 13 to the printing mechanism 11, and can push the printed circuit boards into the printing through groove 1111, retreat after printing, and continue to transfer the printed circuit boards after printing to the rear storage mechanism 14. The entire printing process of the automatic printing machine 1 includes automatic processes of loading, alignment, printing, and unloading. The printing consistency of the printed circuit boards is good, the yield of the products is improved, and the labor is saved.

[0049] The front storage mechanism 13 includes a storage bin 131, a storage bin driving member (not shown in the figure), a turntable 132, and a turntable driving member (not shown in the figure). At least two storage bins 131 are evenly distributed in a circumferential manner on the turntable 132. A plurality of vertically stacked storage slots 1311 are provided on the storage bin 131, and one printed circuit board is inserted into one storage slot 1311. The storage bin driving member can drive the storage bin to move vertically, and the turntable driving member can drive the turntable to rotate.

[0050] The front storage mechanism 13 is a rotary storage mechanism. Multiple printed circuit boards can be accommodated on one storage bin 131. The printed circuit boards are in a plate shape. One storage slot 1311 corresponds to two oppositely arranged C-shaped grooves on the storage bin 131. One C-shaped groove is used for one side of the printed circuit board to be inserted, and the other C-shaped groove is used for the other side of the printed circuit board to be inserted, so as to fix the printed circuit board in the storage slot 1311. The storage slot 1311 penetrates at least on one side through the surface of the storage bin 131, so that the printed circuit board can be inserted into and taken out of the storage bin 131.

[0051] The turntable 132 is placed parallel to the horizontal plane, and the storage bin 131 is erected on the disk surface of the turntable 132. The storage bin driving member can perform reciprocating linear motion in the vertical direction, that is, in the direction perpendicular to the turntable 132, so as to continuously feed the transmission mechanism 12. A plurality of storage bins 131 are arranged on the turntable 132. When one storage bin 131 is empty, the turntable driving member can drive the turntable 132 to rotate, so that another storage bin 131 containing printed circuit boards rotates to the corresponding material taking position, so as to realize continuous feeding without stopping the machine. The empty storage bin 131 can be refilled with new printed circuit boards during the time interval when another storage bin 131 is being fed.

[0052] The turntable driving member can be a rotary power device such as a motor. By adding a speed reducer to the motor, the rotation speed of the motor can be reduced and the speed can be accurately controlled, and the output torque of the motor can be increased, so that the turntable 132 has a more powerful and stable rotation drive, so as to drive the storage bin 131 on the turntable 132 to accurately rotate to the material taking position.

[0053] The storage bin driving component can be a linear motion mechanism such as a linear motor, a ball screw, a gear rack, etc., and the storage bin driving component has an extension and retraction stroke by driving the motor forward and reverse rotation, so that the different storage slots 1311 of the storage bin 131 can be moved to the material picking station, and the retraction stroke is used to reset the position of the storage bin 131 to facilitate reloading.

[0054] Every time the transmission mechanism 12 takes out the printed substrate in the material storage slot 1311, the material storage bin driving component drives the material storage bin 131 to move, and the moving distance is equal to the distance between the two material storage slots 1311, that is, every time the material is taken out, the material storage driving component drives the material storage bin 131 to move one grid position of the material storage slot 1311.

[0055] In this embodiment, the storage bin driver drives the storage bin 131 to move from bottom to top. When the storage bin 131 moves to the top and the transmission mechanism 12 takes away the printed substrate in the storage slot 1311 at the bottom of the storage bin 131, the turntable driver drives the turntable 132 to rotate, and the rotation angle is equal to the angle between the two storage bins 131, so that the storage bin 131 adjacent to the empty storage bin 131 can be filled in time to achieve continuous loading. For example, 5 storage bins 131 are evenly arranged on the circumference of the turntable 132, and the adjacent storage bins 131 form an angle of 72°.

[0056] In another embodiment, the storage bin driving member drives the storage bin 131 to move from top to bottom. When the storage bin 131 moves to the bottom, the transmission mechanism drives the printed substrate in the storage slot 1311 at the top of the storage bin 131, and the turntable driving member drives the turntable 132 to rotate.

[0057] In this embodiment, the storage bin 131 can be separated from the turntable 132, and the turntable 132 is provided with a storage bin driving member under the material-retrieving station, and the position of the storage bin driving member is fixed. The front storage mechanism 13 includes a storage bin driving member, and the storage bin driving member is provided under the turntable 132 corresponding to the material-retrieving station. The storage bin 131 can be separated from the turntable 132, so that when the turntable driving member drives the turntable 132 to rotate, it is not necessary to drive the storage bin driving member to move together, thereby reducing the load of the turntable driving member, reducing energy consumption, and simplifying the structure of the front storage mechanism 13.

[0058] The rear storage mechanism 14 has the same structure as the front storage mechanism 13, and also adopts a rotating storage mechanism to achieve continuous unloading. The storage bin driving member drives the storage bin 131 to move vertically multiple times to unload materials, and the turntable driving member drives the full storage bin 131 to rotate, so as to achieve multiple unloading in the stacking direction and continuous unloading in the rotation direction. The full storage bin 131 can unload the printed substrate during the time interval of unloading materials from another storage bin 131.

[0059] The transmission mechanism 12 includes a material picking assembly 121 , a material feeding assembly 122 , a transverse movement assembly 123 and a vertical movement assembly 124 .

[0060] The material taking component 121 is disposed at the front material storage mechanism 13 , and is used to transfer the printed substrate at the front material storage mechanism 13 to the transverse movement component 123 .

[0061] The material taking assembly 121 includes a material taking driving member 1211 and a material taking pushing block 1212. The material taking driving member 1211 can drive the material taking pushing block 1212 to push the printed substrate in the front material storage mechanism 13 toward the transverse moving assembly 123, and the material taking driving member 1211 has a retraction stroke. The coordinated action of the material taking assembly 121 and the front material storage mechanism 13 realizes continuous loading of the printed substrate.

[0062] Specifically, the material picking drive member 1211 is a reciprocating linear motion mechanism, and the material picking push block 1212 is a thin sheet-like insert. The thickness of the material picking push block 1212 is less than the thickness of the material storage slot 1311, so that the material picking push block 1212 can be repeatedly inserted into the material storage slot 1311 to push the printed substrate in the material storage slot 1311 onto the transverse movement component 123.

[0063] The material storage slot 1311 inserted by the material picking push block 1212 is a material picking station, and the bottom of the material picking station corresponds to the top of the transverse movement component 123, so that it is pushed and translated on the transverse movement component 123 by the material picking push block 1212.

[0064] In this embodiment, the material picking push block 1212 is fork-shaped, and two supporting rollers are provided under the material picking push block 1212 to guide the movement of the material picking push block 1212, so that the material picking push block 1212 can be accurately and smoothly inserted into the material storage slot 1311.

[0065] Each time the material taking drive 1211 drives the material taking push block 1212 to extend and retract, the material storage bin drive drives the material storage bin 131 to move one grid of the material storage slot 1311, so that each insertion of the material taking push block 1212 into the material storage slot 1311 can push out a printed substrate, thereby realizing continuous material taking.

[0066] The transverse shift assembly 123 can move between the front material storage mechanism 13 and the rear material storage mechanism 14 and can stop at the printing table 111, that is, the transverse shift assembly 123 intermittently transmits a printed substrate, stops at the printing table 111 for printing, and transmits again after printing.

[0067] In this embodiment, the transverse moving assembly 123 is a conveyor belt, and the two ends of the conveyor belt are respectively opposite to the front material storage mechanism 13 and the rear material storage mechanism 14. Specifically, the two ends of the conveyor belt are respectively connected to a material storage bin 131 of the front material storage mechanism 13 and a material storage bin 131 of the rear material storage mechanism 14. The material storage slots 1311 on the material storage bin 131, that is, the material taking station and the material feeding station are respectively arranged at the two ends of the conveyor belt. The conveyor belt is used to transfer between the material taking station and the material feeding station. The printing slot 1111 of the printing table 111 is the printing position. The conveyor belt can be stopped when it transfers the printed substrate to the printing position.

[0068] The vertical moving assembly 124 is disposed under the printing table 111 and is used to push the printed substrate between the horizontal moving assembly 123 and the printing through slot 1111 .

[0069] The vertical moving assembly 124 includes a vertical moving driving member 1241 and a vertical moving pushing block 1242 . The vertical moving driving member 1241 can drive the vertical moving pushing block 1242 to push the printing substrate on the transverse moving assembly 123 into the printing through slot 1111 , and the vertical moving driving member 1241 has a retraction stroke.

[0070] The conveyor belt conveys the printed circuit board to the printing position and stops. The vertical driving member 1241 drives the vertical pushing block 1242 to push the printed substrate upward into the printing slot 1111, and the printing head 112 moves to print the printed substrate. Then the vertical driving member 1241 drives the vertical pushing block 1242 to move downward, and the conveyor belt moves again to convey the printed printed substrate to the rear storage mechanism 14. The vertical driving member 1241 is a reciprocating linear motion mechanism, and the vertical pushing block 1242 is a supporting platform for supporting the printed substrate for printing.

[0071] In this embodiment, the vertical push block 1242 is arranged under the conveyor belt, and together with the conveyor belt, pushes the printing substrate toward the printing slot 1111, that is, when the vertical push block 1242 moves upward, it pushes the conveyor belt 1231 upward, and the thickness of the printing table 111 is equal to the thickness of the printing substrate.

[0072] As a result, the conveyor belt remains connected to the printed substrate when stopped and does not separate from the printed substrate during printing, so that the position of the printed substrate on the conveyor belt before and after printing remains unchanged, thereby achieving precise control of the conveying position of the printed substrate.

[0073] The depth of the printing groove 1111 is equal to the thickness of the printing table 111 . When the vertical push block 1242 pushes the printing substrate into the printing groove 1111 , the printing substrate can be exposed on the surface of the printing table 111 , so that the printing head 112 can print on it.

[0074] like Figure 4As shown, the traverse assembly 123 includes a belt 1231, a pulley 1232, a tensioning wheel 1233, and an elastic pulling member 1234. The elastic pulling member 1234 pulls the tensioning wheel 1233, and the elastic pulling member 1234 pulls the tensioning wheel 1233 in the tensioning direction of the belt 1231. The pulley 1232 is used to drive the belt 1231 to move, and the belt 1231 can transmit the printed substrate on its surface by moving and can provide a flat support surface.

[0075] The tensioning wheel 1233 is used to adjust the tightness of the belt 1231, so that a certain pressure is formed between the belt 1231 and the pulley 1232, and the belt 1231 is stably driven to move. The position of the tensioning wheel 1233 is variable, and the elastic pulling of the elastic pulling member 1234 makes the adjustment range of the tightness of the belt 1231 larger. In particular, when the vertical push block 1242 is connected to the belt 1231 and pushes the printed substrate together, the middle part of the belt 1231 is supported and a large deformation occurs. At this time, the elastic pulling member 1234 receives a pulling force, and the position of the tensioning wheel 1233 is also moved upward, providing a deformation margin for the overall upward movement of the belt 1231, effectively preventing the belt 1231 from being damaged by over-tightening, reducing the fatigue stretching of the belt 1231, and extending the service life of the belt 1231.

[0076] The elastic pulling member 1234 is a spring, one end of which is fixed to the body of the automatic printing machine 1 and the other end is connected to the tensioning wheel 1233 for pulling the tensioning wheel 1233 so that the tensioning wheel 1233 tensions the belt 1231 and provides elastic margin for the movement of the tensioning wheel 1233.

[0077] The feeding assembly 122 is disposed at the rear material storage mechanism 14 and is used to transfer the printed substrate on the transverse movement assembly 123 to the rear material storage mechanism 14 .

[0078] The feeding assembly 122 includes a feeding drive 1221 and a feeding push block 1222 . The feeding drive 1221 can drive the feeding push block 1222 to push the printed substrate on the transverse moving assembly 123 toward the rear storage mechanism 14 , and the feeding drive 1221 has a retraction stroke.

[0079] In this embodiment, the feeding component 122 is arranged at one end of the transverse movement component 123 close to the rear storage mechanism 14, the feeding driving component 1221 is arranged under the belt 1231, the belt 1231 is a double belt 1231, and has a certain spacing, the feeding push block 1222 is arranged between the two belts 1231, and the feeding driving component 1221 can drive the feeding push block 1222 to extend out from the two belts 1231 and move toward the rear storage mechanism 14.

[0080] The feed drive 1221 includes a vertical linear motion unit and a horizontal linear motion unit. The feed drive 1221 can drive the feed push block 1222 to float relative to the upper surface of the belt 1231. When the feed push block 1222 moves below the upper surface of the belt 1231, it avoids the transmission of the printed substrate, so that the printed substrate can move from the front end of the feed push block 1222 to the rear end of the feed push block 1222. Here, the front end of the lateral movement assembly 123 is an end provided with a front storage mechanism 13, and the rear end is an end provided with a rear storage mechanism 14.

[0081] After the feeding push block 1222 extends from the upper surface of the belt 1231, the feeding drive 1221 drives the feeding push block 1222 to move toward the rear storage mechanism 14, thereby pushing the printed substrate on the belt 1231 into the storage slot 1311 of the rear storage mechanism 14 to realize the unloading of the printed substrate.

[0082] The distance from the position of the printed substrate transported by the material taking component 121 to the position of the horizontal movement component 123 to the position of the vertical movement component 124 is a first distance, and the distance from the position of the vertical movement component 124 to the position of the material feeding component 122 to feed the material is a second distance, and the first distance is equal to the second distance.

[0083] If the distance from the position where the printed substrate is transferred to the belt 1231 by the material picking component 121 to the end of the belt 1231 is equal to the distance from the position where the printed substrate is transferred to the belt 1231 by the material feeding component 122 before feeding to the end of the belt 1231, then the vertical push block 1242 and the printing slot 1111 correspond to the middle position of the belt 1231.

[0084] Thus, the traverse assembly 123 can simultaneously transport two printed substrates, and during the transport, one printed substrate is synchronously transported from the material taking position to the printing position, and the other printed substrate is transported from the printing position to the feeding position. When one printed substrate is transported to the material taking position, the other printed substrate is just transported to the feeding position. This improves the transport efficiency, makes the printing action more continuous, and improves the printing efficiency of the automatic printing machine 1.

[0085] The working sequence of the automatic printing machine 1 is as follows:

[0086] 1. The material taking driving member 1211 drives the material taking pushing block 1212 to be inserted into the material storage slot 1311, and pushes the printed substrate onto the conveyor belt. This position is the material taking position, and then the material taking driving member 1211 drives the material taking pushing block 1212 to move back and reset.

[0087] 2. The storage bin driving member of the front storage mechanism 13 drives the storage bin 131 to move to the next storage slot 1311, so that the next storage slot 1311 is opposite to the material picking push block 1212. If the material picking slot is the storage slot 1311 at the end of the storage bin 131, the turntable driving member drives the turntable 132 to rotate so that the other storage bin 131 rotates to be opposite to the material picking component 121.

[0088] The conveyor belt moves synchronously with the movement of the storage bin 131, drives the printed substrate to move to the printing position, and another printed substrate on the printing position on the transmission belt moves to the feeding position, and the conveyor belt stops when it moves to the feeding position.

[0089] 3. After the material unloading driving member drives the unloading pushing block to move upward, it moves toward the rear end of the conveyor belt to push the printed substrate into the material storage slot 1311 of the material storage bin 131, and then the material unloading driving member drives the unloading pushing block to move back downward to reset.

[0090] When the unloading component is unloading, the loading component is loading synchronously.

[0091] 4. The storage bin driving member of the rear storage mechanism 14 drives the storage bin 131 to move to the next storage slot 1311, so that the next storage slot 1311 is opposite to the printed substrate pushed by the feeding push block 1222. If the material retrieval slot is the storage slot 1311 at the end of the storage bin 131, the turntable driving member drives the turntable 132 to rotate so that the other storage bin 131 is rotated to be opposite to the printed substrate.

[0092] When the material storage bin 131 of the rear material storage mechanism 14 is in motion, the material storage bin 131 of the front material storage mechanism 13 is in motion synchronously.

[0093] Synchronously with the movement of the storage bin 131, the vertical driving member 1241 drives the vertical pushing block 1242 to move upward, pushing the printed substrate into the printing slot 1111, and then the printing head 112 moves downward to print the printed substrate, and then the vertical driving member 1241 drives the vertical pushing block 1242 to move downward and reset.
