One side of the injection molding machine body is equipped with a pneumatic block via a slider guide rail for material discharge, and the other side is equipped with a material guide slider for material introduction. A linkage block that moves synchronously with the pneumatic block is located on the upper part of the material guide slider. An upper pressure roller and a lower pressure roller are located in the middle of the linkage block to limit and clamp the material. In this invention, the copper sheet is introduced by the material guide slider, and a microswitch detects material breakage and activates the electromagnet assembly inside the linkage block, thereby activating the ratchet and pawl mechanism inside the linkage block.

Description

Technical Field

[0001] This invention relates to the field of copper conductor processing technology, and more particularly to copper conductor injection molding and packaging equipment with material breakage protection. Background Technology

[0002] Copper conductor injection molding encapsulation refers to embedding a copper conductor (such as copper wire, copper foil, or copper sheet) into a plastic substrate, and then using an injection molding process to solidify the plastic material around the copper conductor, forming an encapsulation with a specific shape and structure. This encapsulation technology can protect the copper conductor from external environmental corrosion while improving electrical performance and mechanical strength.

[0003] Currently, in the processing of copper sheets, most encapsulation machines are supplied with material from reels wound with continuous copper sheets (copper conductors). In most cases, the injection molding encapsulation machine and the material reel are separate to facilitate loading and unloading of the material reel. However, in actual use, because there is often a certain distance between the material reel and the injection molding encapsulation machine, the copper sheet bends from the reel and enters the injection molding encapsulation machine in an arc shape. During this process, as each batch of injection molding is completed and the material is unloaded, the copper sheet is subjected to a certain degree of tension and stretching. This causes the copper sheet to easily break or break at the joints and bends of the injection molding encapsulation machine. Traditional processing equipment is mostly not equipped with a material breakage protection mechanism, which means that it takes a long time for operators to notice each material breakage, thus delaying processing efficiency and affecting equipment operation. Therefore, there is an urgent need for copper conductor injection molding encapsulation processing equipment with material breakage protection. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a copper conductor injection molding and packaging equipment with material breakage protection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

One side of the injection molding machine body is equipped with a pneumatic block through a slider guide rail to realize material discharge, and the other side is equipped with a material guide slider to introduce material. The upper part of the material guide slider is equipped with a linkage block that moves synchronously with the pneumatic block. The middle part of the linkage block is equipped with an upper pressure roller and a lower pressure roller to limit and clamp the material.

[0007] The upper and lower pressure rollers extend into the linkage block at both ends and are connected to the upper and lower ratchet wheels. The side away from the upper and lower ratchet wheels is equipped with a pawl assembly by the upper and lower sliders. The upper and lower sliders are controlled to rise and fall by electromagnets that are energized and attracted. The electromagnets are electrically connected to micro switch two, which is installed at one edge of the feeding slider.

[0008] The lower pressure wheel is supported and installed by a pair of rotating arms, and one end of the rotating arm is rotatably connected to the linkage block by an extension shaft. The extension shaft extends into the interior of the linkage block and is connected to a bent steel strip. The bent steel strip is fixedly installed on the inner wall of the linkage block, and a rotating rod is sleeved on the outer wall of the extension shaft.

One end of the linkage rod is connected to the pneumatic block through a connecting block, and the other end is connected to the bottom of the linkage block.

[0012] A control cabinet and a warning light are respectively installed on one side of the upper part of the assembly block.

[0013] In addition, a preferred structure is that the upper part of the lower mold is provided with a pair of sliding grooves to limit the sliding installation of the connecting block, and the bottom end of each sliding groove is connected to the guide groove of the rod body.

[0014] In addition, a preferred structure is that a pair of rod guide grooves are provided on both sides of the middle part of the material guide slider, and a sliding groove is provided on the upper part of the rod guide groove. A linkage block is slidably installed in the sliding groove, and the bottom of the linkage block extends into the rod guide groove and is connected to the linkage rod.

[0015] Furthermore, in a preferred configuration, a one-way roller is rotatably mounted on one side of the upper part of the feeding slider via a mounting bracket, and a one-way limiting plate is provided below the one-way roller by a limiting block one. The limiting block one is vertically slidably limited and mounted on the inner wall of the guide groove two. The limiting block one is connected to the inner wall of the guide groove two via a spring one, and a limiting post is installed on one inner end of the limiting block one. The limiting post extends into the inside of the feeding slider and is connected to the trigger piece of the micro switch one.

[0016] An upper pressure plate is provided on the upper part of the side of the feed slider facing the injection molding machine body. A micro switch two is provided directly below the upper pressure plate. When the copper sheet enters the feed slider, the trigger piece of the micro switch two contacts the bottom wall of the copper sheet and deflects.

[0017] In addition, in a preferred structure, the two ends of the lower pressure wheel are rotatably connected to a pair of rotating arms via a connecting shaft, and the connecting shaft extends out of the outside of the rotating arm and passes through the docking groove opened in the bottom wall of the linkage block, and extends into the interior of the linkage block and connects with the lower ratchet. The ratchet teeth of the lower ratchet and the upper ratchet are arranged in opposite directions.

[0018] In addition, a preferred structure is that an electromagnet is fixedly installed on one side of the middle of the linkage block, and an upper slider and a lower slider are slidably installed on the upper and lower sides of the electromagnet, respectively.

The pawl assembly includes a mounting plate, a second spring, a pin, and a mounting base. The mounting base is connected to the upper slider and the rotating rod respectively. The mounting plate is slidably mounted on one end of the mounting base. The mounting plate and the mounting base are connected by the second spring.

[0021] One end of the rotating rod extends through a through slot one opened in the middle of the lower slider, and is connected to the bottom end of the rotating rod and the through slot one by a spring three.

[0022] The beneficial effects of this invention are as follows:

[0023] In this invention, a copper sheet is introduced by a material-feeding slider, and a micro switch is used to detect material breakage and activate the electromagnet component inside the linkage block. This activates the ratchet and pawl mechanism inside the linkage block. As the pneumatic block and the linkage block move synchronously, the linkage block pushes the broken copper sheet back into the injection molding machine body for timely material replenishment. Compared with traditional processing equipment, this mechanism can effectively realize the material breakage detection function and alleviate the losses caused by material breakage, thus effectively improving processing efficiency.

[0047] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0048] Reference Figure 1-2 A copper conductor injection molding and packaging processing equipment with material breakage protection includes an injection molding machine body 1. An assembly block 6 is assembled on the outer side of the injection molding machine body 1 to guide the copper sheet 3 in the material tray into the machine body. A one-way roller 8 is provided on the upper side of the material guide 7 to limit the copper sheet 3.

[0049] In addition, a slider guide rail 5 is symmetrically installed on the other side of the injection molding machine body 1 and the assembly block 6. The slider guide rail 5, the injection molding machine body 1, and the feed slider 7 are used together to introduce the copper sheet 3.

[0050] Furthermore, a control cabinet 4 and a warning light 41 are installed on the upper side of the assembly block 6.

[0051] Reference Figure 3-6 , Figure 21 The injection molding machine body 1 is equipped with an upper mold 101 and a lower mold 102 to realize basic injection molding and mold closing operations. The lower mold 102 is used for assembling the workpiece, and the upper mold 101 is used for injection molding and mold closing. This is existing technology and will not be explained.

[0052] Furthermore, a guide groove 2 is provided in the middle of the lower mold 102 to limit the workpiece, and a guide slider 7 is provided on the side away from the lower mold 102 to introduce the mating copper sheet 3.

[0053] In addition, the injection molding machine body 1 extends from the other side of the lower mold 102 and a slider guide rail 5 is installed on the upper part of the lower mold 102. A pneumatic block 11 is slidably installed in the middle of the slider guide rail 5 by the guide rail limit. The pneumatic block 11 is connected to an external air source device to realize the pneumatic lateral movement function. The specific connection pipeline and operating principle are already existing technologies, so they will not be described in detail.

[0054] Furthermore, the pneumatic block 11 is provided with a lower top block 111 at its lower part, and the lower top block 111 is connected to an external air source device to achieve top extension.

[0055] Meanwhile, a laser sensor 34 is provided on one side of the bottom wall of the slider guide rail 5, with its sensing direction facing the lower mold 102 directly below.

[0056] In addition, the bottom wall of the pneumatic block 11 is horizontally mounted with linkage rods 10 on both sides by connecting blocks 9. The connecting blocks 9 are slidably installed in a pair of sliding grooves 12 opened on the upper part of the lower mold 102. The bottom of the sliding grooves 12 are connected to the rod guide groove 13. The rod guide groove 13 horizontally penetrates the lower mold 102, and one end of the linkage rod 10 passes through the rod guide groove 13 and exits one side of the lower mold 102.

[0057] Reference Figure 7-10 19, 22, The middle part of the assembly block 6 is equipped with a material guide slider 7. The middle part of the material guide slider 7 is provided with a pair of rod guide grooves 72 to connect with the linkage rod 10 extending from the lower mold 102. The linkage rod 10 is connected to a pair of linkage blocks 16 respectively. The linkage blocks 16 are limited and slidably installed in the slide groove 71 opened on the upper wall of the material guide slider 7. The two ends of the linkage rod 10 are respectively connected to the pneumatic block 11 and the linkage block 16, and the pneumatic block 11 and the linkage block 16 are moved synchronously.

[0058] Among them, the second rod guide groove 72 is horizontally opened on both sides inside the material guide slider 7, and the first slide groove 71 is vertically extended at the upper part of the second rod guide groove 72. The first slide groove 71 is slidably installed in the first slide groove 71, and the bottom of the first slide groove 71 extends into the second rod guide groove 72 and connects with the first slide rod 10.

[0059] Furthermore, the middle part of the feed slider 7 is provided with a guide groove 2 19 corresponding to the guide groove 2, and the inner wall of the guide groove 2 19 is provided with a support platform 191 for supporting the edge of the copper sheet 3.

[0060] Among them, a one-way roller 8 is rotatably mounted on one side of the upper part of the feeding slider 7 via a mounting bracket. The one-way roller 8 is connected to a one-way bearing to achieve one-way clockwise rotation, and a one-way limiting plate 81 is provided on one side of the inner wall of the guide groove 19 below the one-way roller 8.

[0061] Furthermore, one end of the one-way limiting disk 81 is rotatably connected to the limiting block 811 via a one-way bearing, thereby enabling the one-way limiting disk 81 to rotate counterclockwise in one direction. The limiting block 811 is vertically slidably limited and installed on the inner wall of the guide groove 19. The inner wall of the guide groove 19 has a corresponding slot to engage with the limiting block 811. The limiting block 811 is connected to the slot via a spring 21 to achieve the sliding reset function of the limiting block 811. Therefore, when the copper sheet 3 is introduced into the feed slider 7, the copper sheet 3 contacts the one-way roller 8 and the one-way limiting disk 81. The one-way limiting disk 81 is subjected to downward force, and the spring 21 is compressed and stores energy.

[0062] Furthermore, a limiting post 812 is installed on one end of the inner side of the limiting block 811. The limiting post 812 extends into the inside of the feeding slider 7, and the limiting post 812 is connected to the trigger piece of the micro switch 20. The micro switch 20 is fixedly installed in the corresponding position. Therefore, when the unidirectional limiting disk 81 moves vertically in sync with the unidirectional limiting disk 81, the trigger piece of the micro switch 20 deflects to activate at the corresponding stroke position.

[0063] Among them, the upper part of the side of the feeding slider 7 facing the injection molding machine body 1 is provided with an upper pressure plate 15, and a micro switch 151 is provided directly below the upper pressure plate 15. When the copper sheet 3 enters the feeding slider 7, the trigger piece of the micro switch 151 contacts the bottom wall of the copper sheet 3 and deflects. At this time, the micro switch 151 is in an unactivated state.

[0064] Reference Figure 8 , 10 19. The cross section of the linkage block 16 is shaped like the number "7" and is guided and installed by the sliding groove 71 and the rod guide groove 72. The upper pressure wheel 17 and the lower pressure wheel 18 are rotatably installed on the upper and lower sides of the middle part of the linkage block 16, respectively. The upper pressure wheel 17 and the lower pressure wheel 18 are used to limit the copper sheet 3.

[0065] Furthermore, the two ends of the pressure roller 18 are inserted into the inner grooves 192 opened on both sides of the inner wall of the guide groove 19, and are connected to the linkage block 16 through the rotating arm 22.

[0066] Reference Figure 11-1719-20, The upper part of the linkage block 16 is rotatably mounted with an upper pressure wheel 17, and the two ends of the upper pressure wheel 17 extend into the interior of the linkage block 16 and are synchronously connected with an upper ratchet 171.

[0067] Furthermore, a lower pressure wheel 18 is provided at the lower part of the linkage block 16. The lower pressure wheel 18 is rotatably connected to the rotating arm 22 through connecting shafts 182 provided on both sides. The connecting shafts 182 extend out of the outside of the rotating arm 22 and into the docking groove 14 opened in the bottom wall of the linkage block 16. The docking groove 14 connects to the inside of the linkage block 16, so that the connecting shaft 182 extends into the inside of the linkage block 16 and is simultaneously connected to the lower ratchet 181. The ratchet teeth of the upper ratchet 171 and the lower ratchet 181 are arranged in opposite directions.

[0068] Meanwhile, the rotating arms 22 are connected by a connecting shaft 182 to realize the rotation function of the lower pressure wheel 18. The other end of each rotating arm 22 is rotatably installed on the lower part of the linkage block 16 through an extension shaft 221. The extension shaft 221 extends into the interior of the linkage block 16 and is equipped with a bent steel strip 23. The bent steel strip 23 is L-shaped, with one end fixedly connected to the middle of the extension shaft 221, and the other end bent at an incline and fixedly snapped onto the inner wall of the linkage block 16. In the natural state, the bent steel strip 23 generates a torsional force due to bending to drive the extension shaft 221, and the rotating arm 22 is simultaneously deflected to the side of the upper pressure wheel 17 to limit the copper sheet 3 through the lower pressure wheel 18 and the upper pressure wheel 17.

[0069] Furthermore, an upper slider 25 and a lower slider 26 are symmetrically installed on one side inside the linkage block 16. The upper slider 25 and the lower slider 26 correspond to the upper ratchet 171 and the lower ratchet 181. An electromagnet 24 is provided between the upper slider 25 and the lower slider 26. The electromagnet 24 is connected to the upper slider 25 and the lower slider 26 by a return spring 28.

[0070] One end of the upper slider 25 and the lower slider 26 are limited and slidably installed on one side of the inner wall of the linkage block 16, and a ratchet assembly 30 is provided on the top side of the upper slider 25.

[0071] In addition, a rotating rod 27 is rotatably mounted on the outer wall of the extension shaft 221. The other end of the rotating rod 27 extends to a lower slider 26 and passes through one side of the through slot 31 opened in the middle of the lower slider 26. A pawl assembly 30 is installed at one end of the rotating rod 27. The bottom wall of the rotating rod 27 is connected to the through slot 31 by a spring 32 to provide support.

[0072] In its natural state, the rotating rod 27 is set at a downward angle, and the extension is located at the lower ratchet 181 at an angle.

[0073] Specifically, a ratchet assembly 30 is provided on both the upper slider 25 and the rotating rod 27.

[0074] The pawl assembly 30 includes a mounting plate 301, a second spring 302, a pin 303, and a mounting base 304. The mounting base 304 is connected to the upper slider 25 and the rotating rod 27. The mounting plate 301 is slidably mounted on one end of the mounting base 304. The mounting plate 301 and the mounting base 304 are connected by the second spring 302, thereby realizing the telescopic and reset function of the mounting plate 301. The pin 303 is rotatably mounted in the middle of the mounting plate 301.

[0075] Furthermore, magnetic blocks 29 are provided at the ends of the upper slider 25 and the lower slider 26 facing the electromagnet 24. When the electromagnet 24 is energized and generates electromagnetic attraction, the magnetic blocks 29 synchronously drive the upper slider 25 and the lower slider 26 to move towards each other and connect with the electromagnet 24.

[0076] Reference Figure 18 The rotating rod 27 is rotatably mounted on the outer wall of the extension shaft 221. The outer wall of the extension shaft 221 is provided with an arc-shaped groove 33. A limiting block 271 is slidably mounted in the arc-shaped groove 33. The limiting block 271 is mounted on the bottom wall of the rotating rod 27. In its natural state, the rotating rod 27 is set in a downward inclined state, and the limiting block 271 is located at the edge of the arc-shaped groove 33.

[0077] In this embodiment, under normal operating conditions, continuous copper sheets 3 are introduced into the feed slider 7 by the material tray, and the support platform 191 on the feed slider 7 provides support. Then, under manual guidance, the copper sheets 3 are introduced into the injection molding machine body 1 by the feed slider 7. In the initial processing stage, each copper sheet 3 is manually aligned with the injection cavity on the lower mold 102. Then, the control cabinet 4 starts the entire device to perform encapsulation injection molding. Specifically, the injection principle and operation of the injection molding machine body 1 are existing technologies, so they will not be described in detail. Then, in the injection molding mold opening stage, the external air source device drives the pneumatic block 11 to perform lateral displacement and simultaneously pushes the lower ejector block 111. The lower ejector block 111 fits and engages with the molded copper conductor. The lateral movement of the pneumatic block 11 drives the copper sheet 3 to move outward as a whole, and moves the subsequent unprocessed parts to the corresponding injection cavity area with the same movement stroke to repeat the encapsulation injection molding operation.

[0078] 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 to retract the material, the copper sheet 3 will be subjected to a certain degree of traction and stretching, resulting in material breakage.

[0079] Correspondingly, when the copper sheet 3 enters the feed slider 7, it is squeezed and limited by the one-way roller 8 and the one-way limiting plate 81. As the copper sheet 3 is inserted to squeeze the one-way limiting plate 81 downward, the micro switch 20 connected to the one-way limiting plate 81 is pushed up to be activated. After the copper sheet 3 is cut off at this point, the one-way limiting plate 81 loses its force and pushes upward, causing the contact of the micro switch 20 to deflect to activate the micro switch 20.

[0080] Furthermore, after the copper sheet 3 passes through the one-way roller 8 and the one-way limiting plate 81, it is pressed into contact with the upper pressure roller 17 and the lower pressure roller 18, and the upper pressure roller 17 is driven to deflect to adapt to the thickness of the copper sheet 3. Then, when the copper sheet 3 passes the end of the feed slider 7, it contacts the micro switch 151 at one of the upper pressure plates 15.

[0081] In actual use, the linkage block 16, which is equipped with upper and lower pressure rollers, moves synchronously with the pneumatic block 11 through the linkage rod 10, the connecting block 9, and the same moving stroke. Then, due to the relative force, the upper pressure roller 17 and the lower pressure roller 18, which are pressed on the copper sheet 3, rotate in opposite directions, and with each movement, the rollers roll on the surface of the copper sheet 3.

[0082] When the copper sheet 3 breaks at the feeding slider 7, the copper sheet 3 will be divided into the broken section and the raw material end. The broken section will be detected 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 activated simultaneously.

[0083] When the linkage block 16 is activated, the upper pressure roller 17 and the lower pressure roller 18 rotate in one direction. When the linkage block 16 moves outward, i.e. in the direction of feeding the copper sheet 3, the upper pressure roller 17 and the lower pressure roller 18 rotate naturally. When the pneumatic block 11 performs the discharge 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 roller 17 and the lower pressure roller 18 is restricted, and the copper sheet 3 is locked and synchronously conveyed forward. Simultaneously, the waste section is also discharged by the pneumatic block 11, and the raw material section is replenished.

[0084] More specifically, when the internal components of the linkage block 16 are electrically activated, the electromagnet 24 inside the linkage block 16 is energized to generate electromagnetic attraction, and the upper slider 25 and lower slider 26 on its upper and lower sides are attracted by the electromagnet 24. The upper slider 25 moves downward relative to the lower slider 26 and simultaneously drives the pawl assembly 30 on the block to move downward, so that the pawl assembly 30 moves to the upper ratchet 171.

[0085] Synchronously, the lower slider 26 moves upward and is pushed by the through slot 31 in its middle to deflect the rotating rod 27, and the pawl assembly 30 located on the rotating rod 27 moves to the lower ratchet 181.

[0086] As the upper slider 25 and lower slider 26 move into position synchronously, the pawl assembly 30 is simultaneously assembled to the side of the upper ratchet 171 and lower ratchet 181. At this time, the upper pressure roller 17 and lower pressure roller 18 achieve unidirectional rotation through the ratchet and pawl assembly. During the discharge stroke, the upper pressure roller 17 and lower pressure roller 18 rotate towards each other on the surface of the copper sheet 3, causing the pawls of the upper ratchet 171 and lower ratchet 181 to quickly lock and clamp 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 diagonally upward, and the extension shaft 221 synchronously drives the rotating arm 22 to twist diagonally upward, thereby increasing the overall pressing force of the lower pressure roller 18 on the surface of the copper sheet 3, so as to improve the stability of its clamping and locking, and ensure the stability of the copper sheet 3 conveying process.

[0087] As the upper pressure roller 17 and lower pressure roller 18 move back and forth, they will gradually transport the copper sheet 3 into the injection molding machine body 1.

[0088] In actual use, even after the material is cut off, the raw material segment will not fall out of the feeding slider 7 under the one-way locking action of the one-way roller 8 and the one-way limiting plate 81. Instead, it will be gradually conveyed forward by the upper pressure roller 17 and the lower pressure roller 18 after activation.

[0089] In a more general sense, when micro switch 151 is activated by material interruption, micro switch 151 is triggered by control cabinet 4 to stop the injection molding machine body 1 from the current operation, and to energize electromagnet 24, while pneumatic block 11 continues to run to discharge copper sheet 3.

[0090] In actual use, the rotating rod 27 is fitted into the arc-shaped groove 33 on the outer wall of the extension shaft 221 via the limiting block 271. In its natural state, the rotating rod 27 is deflected downwards at an angle. At this time, the limiting block 271 is located on the outermost edge of the arc-shaped groove 33. As the electromagnet 24 actuates the sliding block 26 upwards, the rotating rod 27 deflects upwards synchronously with the sliding block 26. At this time, the relative position of the limiting block 271 in the arc-shaped groove 33 changes and gradually moves to the other edge of the arc-shaped groove 33. Each time the ratchet 181 locks with the pawl assembly 30, the torsional force generated drives the limiting block 271 to press against the groove wall of the arc-shaped groove 33 and transmits the force synchronously to the extension shaft 221.

[0091] In actual use, when the pawl assembly 30 contacts the corresponding ratchet (upper ratchet 171, lower ratchet 181), and the ratchet and pawl rotate in the same direction, the ratchet teeth make rolling contact with the pin 303 on the mounting plate 301, and drive the mounting plate 301 to adaptively extend and retract and reset via the second spring 302. At this time, the ratchet rotates normally. Conversely, when the ratchet and pawl rotate in opposite directions, the ratchet teeth are tightly engaged with the pin 303 and prevent the ratchet from rotating. This is easy to understand intuitively and will not be elaborated here.

[0092] In actual use, the warning light 41 flashes synchronously with the material breakage detection mechanism (micro switch 1 20, micro switch 2 151). Its circuit connection and activation principle are already existing technologies, so they will not be described in detail.

[0093] In actual use, the travel distance of the pneumatic block 11 on the slider guide rail 5 corresponds to the injection area of ​​the upper mold 101. This is easy to understand intuitively and will not be explained further.

[0094] In actual use, the inner groove 192 is used to accommodate the displacement of the linkage block 16 and the rotating arm 22. The groove size of the inner groove 192 is larger than that of the rotating arm 22 to accommodate its deflection range, which is easy to understand intuitively.

[0095] In actual use, the groove size of the docking groove 14 is larger than that of the connecting shaft 182 to accommodate the deflection range of the connecting shaft 182.

[0096] In actual use, as the material segment after material breakage gradually enters 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 the laser sensor 34 set at the bottom of the slider guide rail 5, the laser sensor 34 detects the introduction of the copper sheet 3, and causes the pneumatic block 11 to stop after completing this stroke, and causes the injection molding machine body 1 to perform mold closing and injection. Conversely, when the micro switch 1 20 and the micro switch 2 151 are activated due to material breakage, the injection molding machine body 1 stops injection.

[0097] In actual use, the pawl assembly 30 located on the upper slider 25 and the rotating rod 27 are the same components, and their operating principle and composition structure are the same.

[0098] In actual use, the upper slider 25 and the lower slider 26 are both slidably installed in the grooves corresponding to the inner wall of the linkage block 16. This mechanism is a conventional setting in this field, so it will not be described in detail.

[0099] 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 20, and the micro switch 2 151. When the micro switch 2 151 is triggered, the control cabinet 4 will stop the injection molding machine body 1.

[0100] It is worth noting that the one-way bearing is specifically a one-way bearing, which is a type of bearing that can rotate freely in one direction and is locked in the other. Its working principle mainly relies on the cooperation of internal rolling elements (such as rollers, needle rollers, or wedges) and wedge grooves or ramps. The specific structure and principle not described in detail above are common knowledge known to those skilled in the art, so they will not be elaborated further. Specifically, the one-way bearing enables the one-way rotation function of the one-way roller 8 and the one-way limiting plate 81. Both rotate towards one side of the injection molding machine body 1 to meet the material feeding needs and prevent material from falling out.

[0101] Of particular note are microswitches 20 and 151. Specifically, microswitches are switches with tiny contact intervals and a quick-acting mechanism. They are usually covered by a shell and equipped with a drive rod. Specifically, the drive rod of microswitch 20 is connected to the one-way limit plate 81. When the one-way limit plate 81 is pushed up, i.e., after the material is cut off, it is activated. Similarly, microswitch 151 is activated after the material is cut off and the force of the copper sheet 3 is lost. Its specific structure is already existing technology. Different trigger strokes and nodes can be achieved according to the on-site configuration, which will not be elaborated here.

[0102] It is worth noting that although the upper pressure roller 17 and lower pressure roller 18 after activation can replenish the copper sheet 3 to alleviate the losses caused by the traditional mechanism due to material interruption and shutdown, the operator still needs to reset the machine and reintroduce the material as soon as the material interruption is detected.

[0103] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
