Description

Technical Field

[0001] The invention relates to the technical field of copper conductor processing, in particular to copper conductor injection molding packaging processing equipment with material breaking protection. Background Art

[0002] Copper conductor injection molding refers to embedding copper conductors (such as copper wire, copper foil or copper sheet) into a plastic substrate, and curing the plastic material around the copper conductor through the injection molding process to form a package with a specific shape and structure. This packaging technology can protect the copper conductor from erosion by the external environment while improving electrical performance and mechanical strength.

[0003] At present, in the process of processing copper sheets, most packaging machines are fed by reels wound with continuous copper sheets (copper conductors). In most cases, the injection molding packaging machine and the material reel are split to facilitate the loading and unloading of the material reel. However, in actual use, since there is a certain distance between the material reel and the injection molding packaging machine, the copper sheet is bent from the reel and enters the injection molding packaging machine in a circular arc shape. In this process, as each batch of injection molding is completed and the material is returned, the copper sheet will be pulled and stretched to a certain extent, which causes the copper sheet to easily break and break at the connection and bend of the injection molding packaging machine. However, most traditional processing equipment is not equipped with a material break protection mechanism, so it takes a long time for the operator to discover each material break, which delays the processing efficiency and affects the operation of the equipment.

The bent steel bar 23 is bent in an L shape, one end of which is fixedly connected to the middle part of the extension shaft 221, and the other bent end is inclined and fixedly clamped on the inner wall of the linkage block 16.

[0047] In the present embodiment, under normal working conditions, continuous copper sheets 3 are introduced into the feed slider 7 by the material tray, and the support 191 provided on the feed slider 7 plays a supporting role, and then under the artificial guidance, the copper sheets 3 are introduced into the injection molding machine body 1 by the feed slider 7, and each copper sheet 3 is manually aligned with the injection cavity on the lower mold 102 at the initial stage of processing, and then the control cabinet 4 starts the device as a whole to perform encapsulation injection molding. Specifically, the injection molding principle and operation of the injection molding machine body 1 are already existing technologies, so they are not repeated here. Then, in the injection molding mold opening stage, the pneumatic block 11 is driven by an external air source device to perform lateral displacement, and the lower ejector block 111 is simultaneously extended, and the lower ejector block 111 is engaged and clamped with the molded copper conductor, and the pneumatic block 11 is moved laterally to drive the copper sheet 3 as a whole to move outward, and the subsequent unprocessed parts are moved to the corresponding injection cavity area with the same moving stroke to repeat the encapsulation injection molding operation.

[0048] More specifically, since there is a certain distance or height difference between the reel containing the material and the injection molding machine body 1, during the continuous feeding process of the copper sheet 3, the copper sheet 3 will be drawn out from the reel and bend due to its own weight. As the pneumatic block 11 reciprocates the material, the copper sheet 3 will be pulled and stretched to a certain extent, causing the material to break.

[0049] Correspondingly, when the copper sheet 3 enters the feed slider 7, the one-way roller 8 and the one-way limit plate 81 squeeze and limit the copper sheet 3, and since the copper sheet 3 is inserted to squeeze the one-way limit plate 81 downward, the micro switch 20 connected to the one-way limit plate 81 is lifted up to be activated, and after the copper sheet 3 is cut off here, the one-way limit plate 81 loses its force and pushes up, causing the contact piece of the micro switch 20 to deflect to activate the micro switch 20.

[0050] Furthermore, after passing through the one-way roller 8 and the one-way limit plate 81, the copper sheet 3 is squeezed and contacted with the upper pressing wheel 17 and the lower pressing wheel 18, and the upper pressing wheel 17 is simultaneously driven to deflect to adapt to the thickness of the copper sheet 3. Then, when passing through the end of the feed slider 7, the copper sheet 3 contacts the micro switch 2 151 at the upper pressure plate 15.

[0051] Among them, in actual use, the linkage block 16 equipped with upper and lower pressure wheels is synchronously displaced with the same moving stroke through the linkage rod 10, the connecting block 9 and the pneumatic block 11, and then due to the relative force, the upper pressure wheel 17 and the lower pressure wheel 18 pressed on the copper sheet 3 rotate towards each other, and with each movement, the wheel body rolls on the surface of the copper sheet 3.

[0052] When the copper sheet 3 is broken at the feed slider 7, the copper sheet 3 will be divided into a broken section and a raw material end. The broken section will be recognized as broken by the micro switch 151 at the upper pressure plate 15 during the gradual discharge process, and the internal components of the linkage block 16 will be synchronously stimulated.

[0053] Among them, the linkage block 16 is stimulated to make the upper pressure wheel 17 and the lower pressure wheel 18 rotate in one direction. When the linkage block 16 moves outward, that is, in the feeding direction of the copper sheet 3, the upper pressure wheel 17 and the lower pressure wheel 18 rotate naturally, and when the pneumatic block 11 performs the discharging stroke, the linkage block 16 moves to one side of the injection molding machine body 1. At this time, the rotation function of the upper pressure wheel 17 and the lower pressure wheel 18 is limited, and the copper sheet 3 is locked and conveyed forward synchronously. Synchronously, the waste segment will also be discharged by the pneumatic block 11, and the raw material segment will be refilled.

[0054] More specifically, the internal components of the linkage block 16 are electrically excited, and the electromagnet 24 arranged inside the linkage block 16 is energized to generate electromagnetic attraction, and the electromagnet 24 adsorbs the upper slider 25 and the lower slider 26 on its upper and lower sides accordingly, wherein the upper slider 25 moves downward relatively and synchronously drives the pawl assembly 30 arranged on the block body downward, so that the pawl assembly 30 moves to the upper ratchet 171.

[0055] Synchronously, the lower slider 26 moves upward and the through slot 1 31 opened in the middle thereof pushes the rotating rod 27 to deflect, and the pawl assembly 30 arranged on the rotating rod 27 moves to a position of the lower ratchet wheel 181 .

[0056] As the upper slider 25 and the lower slider 26 move into place synchronously, the pawl assembly 30 is synchronously assembled to the sides of the upper ratchet 171 and the lower ratchet 181. At this time, the upper pressure wheel 17 and the lower pressure wheel 18 are rotated in one direction by the ratchet and pawl assembly, and during the discharging stroke, the upper pressure wheel 17 and the lower pressure wheel 18 rotate toward each other on the surface of the copper sheet 3, and the pawls of the upper ratchet 171 and the lower ratchet 181 are quickly locked and clamped with the pawl assembly 30. At this time, the upper ratchet 171 is locked, and the lower ratchet 181 transmits the torsional force to the rotating rod 27. The rotating rod 27 generates a torsional force obliquely upward, and the extension shaft 221 synchronously drives the rotating arm 22 to twist obliquely upward, and increases the overall tightening force of the lower pressure wheel 18 on the surface of the copper sheet 3, so as to improve its clamping and locking stability and ensure the stability of the copper sheet 3 conveying process.

[0057] As the upper pressing wheel 17 and the lower pressing wheel 18 move back and forth, they gradually transport the copper sheet 3 into the injection molding machine body 1 .

[0058] Among them, in actual use, even after the material is cut off, the raw material segment will not fall out of the material guide slider 7 due to the one-way locking action of the one-way roller 8 and the one-way limit plate 81, but will only be gradually transported forward with the upper pressure wheel 17 and the lower pressure wheel 18 after being stimulated.

[0059] Among them, it is more generally described that when the micro switch 151 is activated at the first material cut-off point, the micro switch 151 is activated by the control cabinet 4 to stimulate the injection molding machine body 1 to stop the operation, and stimulate the electromagnet 24 to be energized, and the pneumatic block 11 keeps running to discharge the copper sheet.

[0060] Among them, in actual use, the rotating rod 27 is installed in the arc groove 33 opened on the outer wall of the extension shaft 221 through the limit block 271. In the natural state, the rotating rod 27 is deflected obliquely downward. At this time, the limit block 271 is at the edge of the arc groove 33, and as the electromagnet 24 stimulates the lower slider 26 to move upward, the rotating rod 27 synchronously deflects the lower slider 26 upward. At this time, the relative position of the limit block 271 in the arc groove 33 changes, and gradually moves to the other edge of the arc groove 33. Each time the lower ratchet 181 is locked with the pawl assembly 30, the torsional force generated drives the limit block 271 to press against the wall of the arc groove 33, and synchronously transmits the force to the extension shaft 221.

[0061] Among them, in actual use, when the pawl assembly 30 contacts the corresponding ratchet (upper ratchet 171, lower ratchet 181), when the ratchet and the pawl rotate in the same direction, the ratchet teeth of the ratchet roll in contact with the pin shaft 303 set on the mounting plate 301, and drive the mounting plate 301 to perform adaptive telescopic reset through spring 2 302. At this time, the ratchet rotates normally. On the contrary, when the ratchet and the pawl rotate in opposite directions, the ratchet teeth are tightly fastened to the pin shaft 303 and prevent the ratchet from rotating. This is easy to understand intuitively and will not be repeated here.

[0062] Among them, in actual use, the warning light 41 flashes synchronously with the excitation of the material break detection mechanism (micro switch 1 20, micro switch 2 151), and its circuit connection and excitation principle are already existing technologies, so they are not repeated here.

[0063] Among them, in actual use, the movement stroke of the pneumatic block 11 on the slider guide 5 corresponds to the injection area of ​​the upper mold 101, which is easy to understand intuitively and no further explanation is given.

[0064] Among them, in actual use, the inner groove 192 is used to meet the displacement of the linkage block 16 and the rotating arm 22. The groove size of the inner groove 192 is larger than the rotating arm 22 to adapt to its deflection range, which is easy to understand intuitively.

[0065] In actual use, the size of the docking slot 14 is larger than the connecting shaft 182 to adapt to the deflection range of the connecting shaft 182 .

[0066] Among them, in actual use, as the raw material segments after material cutting gradually enter the injection molding machine body 1 under the conveying action of the linkage block 16, and when the copper sheet 3 passes through the injection molding machine body 1 and passes through the laser sensor 34 set at the bottom of the slider guide 5, the laser sensor 34 detects the introduction of the copper sheet 3, and stops the pneumatic block 11 after completing the stroke, and enables the injection molding machine body 1 to perform mold closing and injection molding. Conversely, when the micro switch 1 20 and the micro switch 2 151 are activated due to material cutting, the injection molding machine body 1 stops injection molding.

[0067] Among them, in actual use, the pawl assembly 30 arranged on the upper slider 25 and the rotating rod 27 are the same assembly, and their operating principles and composition structures are the same.

[0068] Among them, in actual use, the upper slider 25 and the lower slider 26 are slidably installed in the groove body corresponding to the inner wall of the linkage block 16 by the slider member. This mechanism is a conventional setting in this field, so it will not be repeated.

[0069] In actual use, the control cabinet 4 is electrically connected to the warning light 41, the laser sensor 34, the electromagnet 24, the micro switch 1 151, and the micro switch 2 20. When the micro switch 20 is triggered, the control cabinet 4 triggers the injection molding machine body 1 to stop.

[0070] Among them, it is worth noting that the one-way bearing member is specifically a one-way bearing, which can rotate freely in one direction and is locked in the other direction. Its working principle mainly depends on the cooperation of internal rolling elements (such as rollers, needle rollers or wedge blocks) and wedge grooves or ramps. The specific structure and principle not described in detail above are common knowledge known to technical personnel in this field, so they are not elaborated here. Specifically, the one-way bearing member realizes the one-way rotation function of the one-way roller 8 and the one-way limit plate 81, and the rotation direction of both is toward the side of the injection molding machine body 1 to meet the material feeding and avoid material falling.

[0071] Among them, it is worth noting that the micro switch 20 and the micro switch 2 151 are specifically micro switches. The micro switch is a switch with a small contact spacing and a quick-action mechanism. Its exterior is usually covered with a shell and is equipped with a driving rod; specifically, the driving rod of the micro switch 20 is connected to the one-way limit disk 81, and is stimulated when the one-way limit disk 81 is pushed up, that is, after the material is cut off; similarly, the micro switch 2 151 loses the force of the copper sheet 3 after the material is cut off, and its specific structure is already a prior art, and different trigger strokes and nodes can be achieved according to on-site deployment, which will not be elaborated here.

[0072] Among them, it is worth noting that although the upper pressing wheel 17 and the lower pressing wheel 18 after being stimulated can replenish the copper sheet 3 to alleviate the losses caused by the traditional mechanism due to material shortage and shutdown, the operator is still required to reset the machine and reintroduce the material as soon as possible after discovering the material shortage.

[0073] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
