[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1:

[0035] like Figures 1-12As shown, an embodiment of the present invention provides an automated packaging device for patch production, including a body 1, the lower part of the body 1 includes a placement bin, the body 1 is provided with a bin door at the rear side of the placement bin, a support platform is provided inside the body 1, the support platform includes two vertical side walls, the two vertical side walls are parallel to the length direction of the body 1, a support plate is fixed at the lower end of the two vertical side walls, a rocker 7 is provided between the vertical side walls of the support platform, the rocker 7 includes a support end, a driving wheel group is provided at the lower part of the support platform, and a transmission belt 6 is provided on the outer side of the driving wheel group and the support end of the rocker 7 on the same side. A support member 20 for dynamically supporting the transmission belt 6 is provided in the middle of the rod 7. The above-mentioned rocker arm 7 includes side plates and a support shaft. The support member 20 is fixed to the outer side of the middle part of the support shaft, and both ends are rotatably connected to the support platform. The side plates are distributed on both sides of the support member 20 and are fixed to the support shaft. The support end is located on the side of the side plate away from the top platform. In order to reduce the contact friction between the support end of the rocker arm 7 and the transmission belt 6, a ball bearing can be arranged on the outer side of the support end to contact the transmission belt 6, so as to reduce the friction resistance between the rocker arm 7 and the transmission belt 6 during the swing process, thereby facilitating the relative movement of the support end and the transmission belt 6.

[0036] The support plate of the support platform is installed with an electric cylinder 26, and the output end of the electric cylinder 26 is fixedly installed with a top platform. The top platform is made of cast iron. The longitudinal section of the top platform is an isosceles trapezoid. Side slide grooves are provided on the two inclined surfaces of the top platform. The top platform is provided with a receiving groove with an opening facing downward. The electric cylinder 26 is arranged in the receiving groove. During the retraction of the electric cylinder 26, the top platform cover is driven to the outside of the electric cylinder 26. A pushing component is provided between the side of the top platform and the rocker 7. The pushing component drives the top platform to move up through the electric cylinder 26 to swing the rocker 7. The above-mentioned pushing component includes The cross bar 16, the connecting block 18 and the second connecting rod 19, the vertical side wall of the support table is fixed with a guide groove 17, the cross bar 16 and the connecting block 18 are both slidably connected to the guide groove 17, one end of the cross bar 16 slides with the side slide groove of the top table, and the other end is fixed to the connecting block 18, the second connecting rod 19 rotates with the connecting block 18 and the other end is rotatably connected to the side of the side plate away from the support end. Specifically, after the electric cylinder 26 moves upward, the cross bar 16 generates a pulling force toward the direction of the electric cylinder 26 through the side slide groove. The above-mentioned guide The slot 17 is used to ensure that the cross bar 16 can move horizontally. When the cross bar 16 drives the connecting block 18 to move, the connecting block 18 pulls the rocker arm 7 to rotate around the support axis through the second connecting rod 19, thereby causing the support end corresponding to the side wall to rotate upward, thereby supporting the transmission belt 6 upward. Conversely, as the electric cylinder 26 drives the top platform downward, it can drive the support end corresponding to the side wall to rotate downward, thereby driving the supported part of the transmission belt 6 to move downward. During the process, the support member 20 does not contact the transmission belt 6 when the electric cylinder 26 moves at the two extreme positions, and contacts the transmission belt 6 in other cases. The contact between the transmission belt 6 and the support member 20 provides resistance to the movement of the horizontal part of the transmission belt 6 in the length direction of the support platform. The resistance can be further increased by adding a silicone rubber pad to the contact surface between the support member 20 and the transmission belt 6. In this way, the PCB pads on the transmission belt 6 are prevented from moving along the length direction of the support platform during the period when the rocker arm 7 drives the transmission belt 6 to move up and down, and the spacing between the various PCB pads on the support platform will not change.

[0037] A vibrator 22 is provided on the upper part of the top platform, and a support piece 23 is fixed at the output of the vibrator 22 and the support piece 23 is located on the upper side of the top platform. The two ends of the support piece 23 in the width direction of the support platform are located on the inner side of the transmission belt 6. As mentioned above, the support piece 23 is a steel plate. After the support piece 23 contacts the horizontal part of the transmission belt 6 located at the upper part, the vibration is transmitted to the support piece 23 by starting the vibrator 22, and then the vibration of the support piece 23 and the transmission belt 6 is transmitted to the PCB pad, thereby reducing residual bubbles in the solder paste. During the process, the transmission belt 6 is in a tensioned state through the guide groove 17, and the PCB pad is clamped by the transmission belt 6 and the pressure plate 10.

[0038] A fixed seat 15 is fixed to the rear side of the support table, and a slider 24 is slid on the inner side of the fixed seat 15. A third connecting rod 27 is rotatably arranged between the slider 24 and the top table. A connecting frame 5 is rotatably connected in the fixed seat 15, and a solder paste scraping assembly is fixed to the other end of the connecting frame 5. The solder paste scraping assembly includes a solder paste coating frame 4, which is fixed to the connecting frame 5. A first connecting rod 14 is rotatably connected between the slider 24 and the connecting frame 5. The support table is symmetrically provided with slide grooves on both sides of the solder paste scraping assembly, and a centrally symmetrically distributed pressure plate 10 is provided in the slide groove. The pressure plates 10 are used to clamp the solder paste scraping template. The solder paste scraping assembly cooperates with the solder paste scraping template. The support table is provided with a T-mouth between the slide grooves on the same vertical side wall, and the T-mouth is used to support the solder paste coating frame 4. In the above, the electric cylinder 26 drives the top platform to move upward, drives the third connecting rod 27 to pull upward, and then drives the slider 24 to move along the fixed seat 15 toward the top platform, and then the slider 24 pulls the first connecting rod 14 to rotate the connecting frame 5 forward, and then drives the solder paste coating frame 4 to rotate forward to the T-mouth. After the electric cylinder 26 drives the top platform to move up to the limit position, the solder paste coating frame 4 is horizontally arranged at the T-mouth, and a solder paste adding port is provided on the rear side of the machine body 1. After the electric cylinder 26 drives the top platform to move downward, the top platform presses the third connecting rod 27 downward, pushing the slider 24 to move away from the top platform, and then the slider 24 causes the connecting frame 5 to drive the solder paste coating frame 4 to move toward the solder paste adding port through the first connecting rod 14, thereby facilitating the addition of solder paste into the solder paste coating frame 4.

[0039] The inner side of the solder paste coating frame 4 is provided with a slide bar 9 that moves along the width direction of the support platform. The solder paste coating frame 4 is rotated with a screw 13 that drives the slide bar 9 to move through a thread. The screw 13 is fixed to a side motor 28 on which the solder paste coating frame 4 is connected to the connecting frame 5. A contact switch is provided on the T-mouth. After the contact switch is pressed, the side motor 28 is started. The slide bar 9 includes at least two downward U-mouths. The opposite sides of the U-mouth are provided with notches and a fixed shaft 31 is movable in the notch. A movable block 8 is fixed on the outer side of the fixed shaft 31. The movable block 8 is provided with a top mouth at a position below the fixed shaft 31. A scraper 29 with an inclined direction opposite to the moving direction is provided on the lower side of the movable block 8. A spring piece 32 is fixed between the upper side of the movable block 8 and the U-mouth. The spring piece 32 is made of a spring plate with a thickness of 1 mm. The spring piece 32 includes protrusions at both ends facing the U-mouth. The U-mouth is provided with card holes 30 on both sides of the notch. A spring piece 32 is fixed on the side wall of the solder paste coating frame 4 to push the movable block 8 to swing. U block, after the side motor 28 is started, the side motor 28 drives the screw 13 to rotate, causing the slide bar 9 to move back and forth, thereby driving the scraper 29 to scrape the solder paste onto the solder paste scraping template, and then the solder paste adheres to the PCB pad. The vibration generated by the vibrator 22 creates a gap between the solder paste attached to the PCB pad and the solder paste scraping template, which facilitates the separation of the solder paste attached to the PCB pad from the solder paste scraping template. After the side motor 28 drives the slide bar 9 to move through the screw 13, so that the U mouth is close to the U block, the movable block 8 is lifted up and down from the top mouth through the lower part of the U block, and the spring piece 32 is compressed. At the same time, the upper part of the U block pushes the movable block 8 to rotate on the upper part of the fixed shaft 31, and the U block pushes the protrusion of the spring piece 32 to be stuck in the card hole 30 in the moving direction, thereby driving the scraper 29 connected to the movable block 8 to flip, that is, change the direction. The protrusion in the above-mentioned is separated from the card hole 30, so that the push of the U block is achieved in the process of the movable block 8 approaching the U block.

[0040] The vertical side wall of the vertical support platform of the pressure plate 10 is provided with a pressure block 1 which can be adjusted up and down by a bolt. A pressure opening 1 is provided on the lower side of the pressure plate 10. The pressure opening 1 includes a side plane parallel to the vertical side wall, which contacts the side of the PCB pad through the side plane of the pressure plate 10. A silicone convex ball is provided on the lower side of the pressure block 1. The above-mentioned pressure block 1 and the pressure plate 10 are vertically slidably matched. The bolt is threadedly connected to the side wall included in the pressure plate 10 above the pressure block 1, and the lower end of the bolt is rotatably connected to the pressure block 1. The silicone convex ball is used to squeeze the PCB pad after the transmission belt 6 drives the PCB pad to move upward, so as to increase the friction with the PCB pad.

[0041] The driving wheel group includes four guide wheels 21 rotatably connected to the vertical side walls of the support platform. The transmission belt 6 is coordinated with the guide wheels 21 on the corresponding side. A dual-output shaft motor 12 is arranged between the two guide wheels 21 in the length direction of the support platform. The above-mentioned dual-output shaft motor 12 is installed on the support plate.

[0042] The machine body 1 includes a controller, which is connected to the contact switch, the electric cylinder 26, the dual output shaft motor 12 and the side motor 28 to realize the control function.

[0043] Example 2:

[0044] In this embodiment, based on the first embodiment, a patch feeder 3 is provided at the front side of the support platform, and the machine body 1 also includes a driving nozzle mechanism (not shown in the drawings). A second pressing plate 11 is provided in the chute on one side of the solder paste coating frame 4. The second pressing plate 11 is located on the side of the first pressing plate 10 away from the solder paste coating frame 4. The part of the first pressing plate 10 extending out of the chute is L-shaped. The solder paste scraping template is clamped between the inner sides of the L-shaped parts corresponding to the first pressing plate 10. The part of the second pressing plate 11 perpendicular to the vertical side wall of the support platform is also provided with a pressing plate that can be adjusted up and down by bolts. A second pressure port is provided on the lower side of the second pressing plate 11, and a silicone convex ball is provided on the lower side of the pressing plate. The driving nozzle mechanism includes a front and rear driving component and a left and right driving component. The left and right drive components are installed at the output ends of the front and rear drive components. A placement head is provided at the output ends of the left and right drive components. The front and rear drive components and the left and right drive components can both use linear motors. The placement head is a mature existing technology, such as the placement head of the YRM20 high-speed and high-efficiency module placement machine of Suzhou Tekway Intelligent Technology Co., Ltd., which can be freely selected according to needs. During the placement process, the front and rear drive components and the left and right drive components drive the movement of the placement head, so that the placement head takes material from the patch feeder 3 and performs placement according to a preset program. In the above, the corner of the pressure port 2 of the pressure plate 2 11 is used as the positioning starting point of the PCB pad, and it is completed through the control of the corresponding pre-examination programming program.
