Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing technology, specifically to a meter for measuring the amount of thermally conductive silicone used in PCBA. Background Technology

[0002] In the production and manufacturing of PCBA (Printed Circuit Board Assembly), in order to ensure the heat dissipation performance of electronic components such as chips, capacitors, and power devices, thermally conductive silicone is applied between the components and heat dissipation structures such as heat sinks and metal casings. The high thermal conductivity of silicone enables rapid heat conduction, preventing the components from degrading or being damaged due to overheating. Existing thermal silicone dispensing machines require different diameters and shapes of dispensing heads, such as dispensing heads, wire dispensing heads, and surface dispensing heads, to match different specifications of PCBA components. The dispensing heads are mostly connected to the machine body by bolts or welding. Replacement requires special tools for disassembly, which is time-consuming. Repeated disassembly can easily lead to wear on the connection parts, affecting the dispensing stability. For small-batch, multi-variety production scenarios, the equipment changeover efficiency is difficult to meet the requirements, thus reducing the production efficiency of the thermal silicone dispensing machine.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 - Figure 6A PCBA-grade thermal conductive silicone dispensing machine includes a feeding cylinder 1, a conveying extrusion cylinder 2 at the bottom of the feeding cylinder 1, a mounting plate 2 6 fixedly mounted on the outer wall of the feeding cylinder 1, a screw conveyor 3 inside the conveying extrusion cylinder 2, a mounting plate 4 on the outer wall of the conveying extrusion cylinder 2, a dispensing head module 5 on the outer wall of the mounting plate 4, a display screen 7, a photoelectric switch 8, an emergency stop switch 9, and a feeding switch 10 on the outer wall of the mounting plate 6, a connecting rod 11 at the top of the feeding cylinder 1, a cylinder 12 fixedly mounted on the other end of the connecting rod 11, a cutting blade 14 fixedly mounted on the telescopic end of the cylinder 12, a support frame 13 on the outer wall of the dispensing head module 5, and a connecting assembly 15 on the inner wall of the dispensing head module 5. The inner wall of the frame 13 is provided with a dredging component 16, and the connecting component 15 includes a slot 151. The slot 151 includes a first slot 1511 opened in the inner wall of the mounting plate 4. The inner wall of the dispensing head module 5 is provided with a circular groove 1512. The inner wall of the mounting plate 4 is provided with a second slot 1513 and a guide groove 1514. The inner cavity of the circular groove 1512 is provided with a first spring 152 and a convex slot 153. The inner wall of the convex slot 153 is provided with a third slot 154. The inner cavity of the guide groove 1514 is provided with a locking pin 155 and a second spring 156. The outer wall of the locking pin 155 is fixedly installed with an unlocking lever 157, and the outer wall of the convex slot 153 is fixedly installed with an unlocking lever 158. In the above structure, by starting the screw conveyor 3, the rubber material in the inner cavity of the feed cylinder 1 is squeezed by the rotation of the screw conveyor 3 and extruded into the required shape through the extrusion head module 5 of the conveying extrusion cylinder 2.

[0018] In a preferred embodiment: the connecting component 15 is regarded as a group of movable components, and the number of such movable components is four groups, which are arranged in a rectangular array at the connection between the mounting plate 14 and the dispensing head module 5. The outer wall of the cutting blade 14 is slidably fitted against the outer wall of the dispensing head module 5. In the above structure, the cylinder 12 drives the cutting blade 14 to slide downward along the outer wall of the dispensing head module 5, so that it can quickly cut the glue after a single dispensing, thereby avoiding the phenomenon of glue sag due to its own weight and ensuring the regularity of dispensing. At the same time, when disassembling the dispensing head module 5 to replace it with a different specification, the dispensing head module 5 and the mounting plate 4 are disconnected by connecting components 15 arranged in a rectangular array. Then, when installing the dispensing head module 5 of different specifications, the dispensing head module 5 is connected to the mounting plate 4 again by the four sets of rectangular connecting components 15, so as to achieve quick replacement and assembly without tools.

[0019] In a preferred embodiment: the outer wall of the dispensing head module 5 is adapted to the inner wall shape of the first slot 1511, the outer walls of the four convex slots 153 are slidably fitted to the inner wall of the circular groove 1512, the four first springs 152 are located at the top of the circular groove 1512, one end of which overlaps with the outer wall of the first spring 152 and the other end overlaps with the inner wall of the circular groove 1512, and the bottom of the four convex slots 153 is adapted to the inner wall shape of the second slot 1513; In the above structure, by aligning the dispensing head module 5 with the four sets of first slots 1511 opened in the inner wall of the mounting plate 4, and then pushing the dispensing head module 5 with external force, the outer wall of the dispensing head module 5 is inserted into the inner cavity of the four sets of first slots 1511. At this time, the convex slot 153 contacts the inner wall of the first slot 1511, causing the convex slot 153 to be squeezed by its inner wall and slide along the inner wall of the circular groove 1512. This sliding causes the first spring 152 to be compressed. At this time, the convex slot 153 is in contact with the inner wall of the second slot 1513. Correspondingly, the convex slot 153 is reset by the rebound of the first spring 152 and inserted into the inner cavity of the second slot 1513, thereby achieving the first stage of fixation. Then, when the first stage of fixation is contacted, the second unlocking lever 158 can be pulled, causing one end of the second unlocking lever 158 to drive the convex slot 153 to slide along the inner wall of the first circular groove 1512. The first spring 152 is compressed again due to the sliding of the convex slot 153, causing the convex slot 153 to retract into the inner cavity of the first circular groove 1512, thereby releasing the first stage of fixation.

[0020] In a preferred embodiment: the bottom of the four convex slots 153 is slidably disposed in contact with the outer wall of the locking pin 155, the inner wall of the four third slots 154 is adapted to the shape of the outer wall of the locking pin 155, the outer wall of the four locking pins 155 is slidably disposed in contact with the inner wall of the guide groove 1514, and the four second springs 156 are located on one side of the locking pin 155, with one end overlapping the outer wall of the locking pin 155 and the other end overlapping the inner wall of the guide groove 1514; In the above structure, when the convex slot 153 is inserted into the inner cavity of the second slot 1513, the bottom of the convex slot 153 contacts the outer wall of the locking pin 155. This causes the locking pin 155 to slide along the inner cavity of the guide groove 1514 due to the pressure from the convex slot 153. The sliding third slot 154 then compresses the second spring 156, so that when the locking pin 155 aligns with the inner cavity of the third slot 154, the second spring 156 returns the locking pin 155 to its original position and inserts it into the third slot 154. The inner cavity is used to fix the convex slot 153, thereby preventing the connection between the dispensing head module 5 and the mounting plate 4 from loosening due to vibration. Secondly, by pulling the unlocking lever 157, one end of the unlocking lever 157 will drive the locking pin 155 to slide along the inner wall of the guide groove 1514 again, so that the second spring 156 will be compressed again, thereby causing the locking pin 155 to exit the inner cavity of the third slot 154, thereby releasing the fixation of the convex slot 153, so that the convex slot 153 can be released from fixation.

[0021] In a preferred embodiment: the unblocking component 16 includes an inclined plate 161 rotatably connected to the inner wall of the support frame 13. The inner wall of the inclined plate 161 is provided with a groove 162, the inner wall of the groove 162 is provided with a ball groove 163, the inner wall of the inclined plate 161 is provided with a slider 164, the top of the slider 164 is fixedly installed with an unblocking needle 169, the inner wall of the slider 164 is provided with a circular groove 165, the inner wall of the circular groove 165 is fixedly installed with an arc-shaped ring plate 166, and the inner cavity of the circular groove 165 is provided with a lock ball 167 and a third spring 168 respectively. In the above structure, when the dispensing head module 5 is not in use, the outlet of the dispensing head module 5 can be unblocked by the unblocking component 16 on the inner wall of its screw conveyor 3, thereby avoiding the phenomenon of outlet blockage caused by the fixed adhesive material at the outlet of the dispensing head module 5.

[0022] In a preferred embodiment: slider 164, circular groove 165, arc ring 166, lock ball 167, third spring 168, and unclogging needle 169 are regarded as a set of movable components, and there are two sets of such movable components, which are symmetrically arranged with the dispensing head module 5 as the center. In the above structure, by operating the two sets of movable components on both sides of the outer wall of the inclined plate 161, the slider 164, the circular groove 165, the arc-shaped ring 166, the lock ball 167, the third spring 168, and the unblocking needle 169 move closer to the outlet of the glue dispensing module 5, the two sets of movable components will penetrate the glue blockage at the opening of the glue dispensing module 5 through the unblocking needle 169. The glue will then be removed by the reverse operation of the inclined plate 161 after being penetrated by the two unblocking needles 169.

[0023] In a preferred embodiment: the outer walls of the two sliders 164 are slidably fitted against the inner wall of the slide groove 162; the diameter of the two lock balls 167 is larger than the opening diameter of the arc-shaped ring 166; the outer walls of the two lock balls 167 are adapted to the shape of the inner walls of the four ball grooves 163; the two third springs 168 are located on one side of the two lock balls 167, and one end of the two third springs 168 overlaps with the outer wall of the two lock balls 167, and the other end overlaps with the inner wall of the two circular grooves 165; the number of ball grooves 163 is four, and the four ball grooves 163 are respectively arranged parallel to each other on the inner wall of the slide groove 162; In the above structure, by sliding the two sets of sliders 164 toward the opening of the dispensing head module 5, the two sets of locking balls 167 will disengage from the inner wall of the initially fixed ball groove 163 under the sliding of the two sliders 164, so that the locking balls 167 will contact the inner wall of the slide groove 162, and then the locking balls 167 will be squeezed by the inner wall and disengaged from the opening of the arc-shaped ring piece 166, so that the locking balls 167 will drive the third spring 168 to compress. At this time, the two sets of movable components are slid to the corresponding opening of the dispensing head module 5, so that the two locking balls 167 will rebound and reset to the opening of the arc-shaped ring piece 166 and engage with the corresponding ball groove 163 by the two third springs 168, thereby fixing the two sets of sliders 164. Then, when it is not necessary to clear the opening of the dispensing head module 5, the two sets of movable components can be slid to both sides of the outer wall of the inclined plate 161 by the reverse operation.

[0024] In a preferred embodiment: the distance between the inclined plate 161 and the dispensing head module 5 is 120 degrees, and the two unclogging needles 169 are correspondingly arranged with respect to the outlet end of the dispensing head module 5. In the above structure, after the two sets of movable components are fixed, the two unclogging needles 169 will correspond to the outlet of the dispensing head module 5. At this time, the inclined plate 161 is pushed by external force, and the inclined plate 161 will rotate 120 degrees along the inner wall of the support frame 13 to fit against the outer wall of the dispensing head module 5. When it fits, the two unclogging needles 169 will penetrate the glue at the opening of the dispensing head module 5, thereby achieving penetration of the glue that is blocking it. By reversing the operation, the two unclogging needles 169 will simultaneously drive the glue that is blocking it under the action of the inclined plate 161, thereby unclogging it.

[0025] Working principle: First, by activating the feeding switch 10, the screw conveyor 3 starts operating, pushing the rubber material in the feeding cylinder 1 to the conveying extrusion cylinder 2 through rotational extrusion. Finally, it is extruded into the desired shape by the dispensing head module 5. After a single dispensing, the cutting blade 14 is driven by the cylinder 12 to slide downwards along the outer wall of the dispensing head module 5, quickly cutting the rubber material. Secondly, if it is necessary to replace the dispensing head module 5 with a different specification, firstly, the unlocking lever 157 is pulled, causing one end of the unlocking lever 157 to drive the locking pin 155 to slide along the inner cavity of the guide groove 1514. The sliding guide groove 1514 will drive the second spring 156 to compress. At this time, the locking pin 155 will be pushed out of the inner cavity of the third slot 154. This releases the fixation of the convex slot 153. Then, by pulling the unlocking lever 158, one end of the lever 158 causes the convex slot 153 to slide along the inner cavity of the circular groove 1512. This sliding convex slot 153 simultaneously compresses the first spring 152, causing it to exit the inner cavity of the second slot 1513, thus releasing its lock. Subsequently, by pushing the dispensing head module 5, its outer wall exits the inner cavity of the four sets of first slots 1511 on the inner wall of the mounting plate 4, thus enabling the dispensing head module 5 to be installed on the mounting plate 4. Furthermore, when installing dispensing head modules 5 of different specifications and models, the dispensing head module can be installed by... The four sets of first slots 1511 in the inner wall of the mounting plate 4 are aligned again, so that the outer wall of the dispensing head module 5 is inserted into the inner cavity of the four sets of first slots 1511. At this time, the bottom of the convex slot 153 contacts the inner wall of the first slot 1511, so that the convex slot 153 is squeezed by its inner wall and slides along the inner wall of the circular groove 1512. This sliding causes the first spring 152 to be compressed. When the convex slot 153 corresponds to the inner wall of the second slot 1513, the convex slot 153 is reset by the rebound of the first spring 152 and inserted into the inner cavity of the second slot 1513. When the convex slot 153 is inserted into the inner cavity of the second slot 1513, the bottom of the convex slot 153 will engage with the locking pin 15. The outer walls of the 5-piece dispensing head module 5 come into contact with each other, causing the locking pin 155 to slide along the inner cavity of the guide groove 1514 due to the compression of the convex slot 153. This causes the sliding third slot 154 to drive the second spring 156 to compress, so that when the locking pin 155 aligns with the inner cavity of the third slot 154, the locking pin 155 is reset by the rebound of the second spring 156 and inserted into the inner cavity of the third slot 154, thus fixing the convex slot 153. This prevents the connection between the dispensing head module 5 and the mounting plate 4 from loosening due to vibration, and allows for complete disassembly and assembly of the dispensing head module 5 of different specifications. Furthermore, to prevent the outlet of the dispensing head module 5 from being blocked by solidified glue, the two sets of sliders 164 slide towards the opening of the dispensing head module 5.At this point, the two sets of lock balls 167 will disengage from the inner wall of the initially fixed ball groove 163 under the sliding of the two sliders 164, causing the lock balls 167 to contact the inner wall of the groove 162. This causes the lock balls 167 to be squeezed against the opening of the arc-shaped ring 166, resulting in the lock balls 167 driving the third spring 168 to compress. Then, the two sets of movable components are slid to correspond to the opening of the dispensing head module 5, allowing the two lock balls 167 to rebound and reset to the opening of the arc-shaped ring 166 using the two third springs 168, locking with the corresponding ball groove 163. Next, the two sets of sliders 164 are fixed in this way. After fixing, the two unblocking needles 169 will correspond to the outlet of the dispensing head module 5. Then, by pushing the inclined plate 161 with external force, the inclined plate 161 will rotate 120 degrees along the inner wall of the support frame 13, so that it can fit against the outer wall of the dispensing head module 5. When it fits, the two unblocking needles 169 will penetrate the glue at the opening of the dispensing head module 5, thereby penetrating the glue that is blocking it. By reversing the operation, the two unblocking needles 169 will be driven by the inclined plate 161 to simultaneously move the blocking glue, thereby clearing the blockage.
