Description

Technical Field

[0001] This invention relates to the field of continuous single-sided strip technology, and more specifically, to a terminal embedding device and its embedding process for single-sided continuous strip. Background Technology

[0002] As a critical infrastructure of communication networks, the stability and reliability of the internal electronic components of base stations directly affect communication quality and efficiency. Terminal blocks, as essential components for electrical connections in base stations, are crucial to their normal operation due to their processing quality. In the production process of base station terminal blocks, single-sided continuous strip is a commonly used raw material for subsequent terminal embedding to form a complete terminal block.

[0003] Currently, equipment used for processing single-sided continuous strip to produce terminal blocks presents numerous problems affecting product quality when processing the single-sided strip used to produce single-sided strips. While this traditional processing method and equipment can achieve initial forming of the single-sided strip to some extent, its stability is poor because the strip is only connected to the carrier on one side. During injection molding, the formed U-shaped groove is prone to angular deviation due to the swaying of the single-sided strip. This deviation directly affects the embedding accuracy of subsequent terminals, thus impacting the electrical connection performance of the entire terminal block.

[0004] When the aforementioned angular deviation occurs, correcting it by re-closing the mold will cause new problems. Due to the large clamping force, the already unstable U-shaped groove will be damaged. This damage may lead to changes in the shape of the U-shaped groove, dimensional deviations, etc., resulting in the batch of products being unqualified.

[0005] Therefore, developing a terminal embedding device and its embedding process for single-sided continuous strips that can effectively solve the above problems is of great practical significance. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a terminal embedding device with an embedding mechanism for a single-sided continuous strip and the embedding process thereof.

[0007] To achieve the above objectives, the present invention provides the following technical solution: The present invention is further configured to include an injection molding machine, a robotic arm mounted on the injection molding machine, and a moving mold and a stationary mold mounted on the injection molding machine. It also includes a pre-pressing unit, an auxiliary demolding unit, and an auxiliary unloading unit. The pre-pressing unit is located at the top of the robotic arm and includes abutment portions. Multiple abutment portions are used to abut against the single-sided strip to be processed. Multiple abutment portions are provided, and when the robotic arm moves the pre-pressing unit towards the moving mold, the multiple abutment portions can abut against the end face of the single-sided strip to be embedded, thereby pre-pressing and positioning the single-sided strip. The auxiliary demolding unit is located on the first die-casting plate and is used to adsorb the injection molding surface of the pre-pressed and positioned single-sided strip to achieve auxiliary demolding of the single-sided strip. The auxiliary unloading unit is used to clamp the adsorbed and demolded single-sided strip and drive the single-sided strip to move along a preset direction, so that the adsorbed single-sided strip maintains a parallel posture with the moving mold, facilitating subsequent unloading.

[0008] By adopting the above technical solution, the U-shaped groove of the single-sided strip can be guaranteed to be qualified after the mold is opened through the abutment embedding of multiple abutment parts. This avoids the angle deviation of the U-shaped groove due to strip offset after subsequent injection molding from the source, and eliminates the need to rely on mold closing for correction.

[0009] The present invention is further configured such that: the pre-pressing unit includes a first die-casting plate and a second die-casting plate; the first die-casting plate is fixedly mounted on the working end of the robotic arm; the second die-casting plate is slidably disposed on the side of the first die-casting plate, and the side of the second die-casting plate is fixedly installed with a plurality of abutting parts, so that when the first die-casting plate and the second die-casting plate move, the plurality of abutting parts can be driven to move synchronously.

[0010] The invention is further configured such that: the pre-pressing unit includes a positioning rod, a damping spring, a first limiting part, and a second limiting part; multiple positioning rods are respectively disposed on the side of the first die-casting plate, and the multiple positioning rods are respectively clearance-fitted with the second die-casting plate; the damping spring is disposed on the outside of the positioning rod, one end of the damping spring is fixed to the end face of the first die-casting plate, and the other end of the damping spring is fixed to the end face of the second die-casting plate; multiple first limiting parts are respectively disposed on the moving mold; multiple second limiting parts are respectively disposed on the moving mold, and the end faces of the first limiting part and the second limiting part are each provided with an opening facing the stationary mold direction, and the opening is used to abut against a single-sided strip of material.

[0011] The present invention is further configured such that: the auxiliary demolding unit includes a vacuum pump, a sealing box, and an adsorption section; the vacuum pump is disposed on the first die-casting plate; the sealing box is disposed on the side of the first die-casting plate, and the sealing box is connected to the vacuum pump through a telescopic tube; the adsorption section has multiple adsorption sections and is disposed on the first die-casting plate respectively, and the adsorption ends of the multiple adsorption sections are respectively facing the middle of the single-sided material strip, and the multiple adsorption sections are respectively connected to the sealing box.

[0012] The present invention is further configured such that: multiple adsorption sections are evenly distributed along the conveying direction of the single-sided material strip, and the spacing between adjacent adsorption sections is adapted to the workpiece spacing of the single-sided material strip.

[0013] The present invention is further configured such that the adsorption end of the adsorption part is a circular bonding surface, and the diameter of the circular bonding surface is consistent with the diameter of the middle end face of the injection molded part of the single-sided strip.

[0014] By adopting the above technical solution, each adsorption part can act specifically on the corresponding single-sided strip workpiece, ensuring that each workpiece on the continuous single-sided strip can be stably adsorbed, avoiding the problems of missed adsorption and multiple workpieces being adsorbed due to the mismatch between the spacing of the adsorption parts and the spacing of the workpieces. At the same time, it avoids the situation where the unadsorbed single-sided strip is pulled and damaged due to its attachment to the first and second limiting parts when only a few single-sided strips are adsorbed, thus ensuring the orderliness of the demolding process.

[0015] The present invention is further configured such that: the auxiliary unloading unit includes a mounting frame, a first rotating part and a second rotating part; the mounting frame is slidably disposed at the bottom of the injection molding machine; the first rotating part is rotatably disposed on the mounting frame; the second rotating part is rotatably disposed on the first rotating part, and a reserved space is left between the first rotating part and the second rotating part for the passage of a single-sided material strip.

[0016] The present invention is further configured such that: the auxiliary unloading unit also includes a first rotary driver and a fixing part; the first rotary driver is disposed on the side of the first rotating part, and the output end of the first rotary driver is connected to the input end of the first rotating part, so that when the first rotary driver is started, it can drive the first rotating part to rotate; the fixing part has a pair and is disposed on the side of the mounting frame, and the pair of fixing parts are respectively located below the first rotating part and the second rotating part, and an opening is left between the pair of fixing parts for the single-sided material strip to pass through.

[0017] The invention is further configured such that: the auxiliary unloading unit also includes a positioning frame, a linear sliding part, and a linear motor; the positioning frame is located at the bottom of the injection molding machine, and the top of the positioning frame has a stroke chamber for the mounting frame to slide; the linear sliding part is slidably located at the bottom of the positioning frame, and the top of the linear sliding part is fixedly connected to the mounting frame; the linear motor is located on the side of the positioning frame, and the output end of the linear motor is provided with a screw threadedly connected to the linear sliding part, so that when the linear motor is started, the linear sliding part and the mounting frame can be driven to move along the stroke chamber at the top of the positioning frame through the screw.

[0018] By adopting the above technical solution, the mounting frame can slide in the stroke cavity at the top of the positioning frame. The linear sliding part drives the mounting frame to move in a straight line along the stroke cavity in sync with the auxiliary demolding unit and match the moving distance of the auxiliary demolding unit, thus avoiding bending damage to the continuous single-sided strip and ensuring the processing qualification rate.

[0019] A terminal embedding process, using the terminal embedding device for a single-sided continuous strip as described above, includes the following steps: S1. The robotic arm starts, driving the fixed first die-casting plate, the second die-casting plate slidably disposed next to the first die-casting plate, and multiple abutting parts on the second die-casting plate to move towards the moving mold; during the movement, the abutting parts are embedded into the U-shaped groove area of ​​the single-sided material strip, and at the same time, the single-sided material strip initially abuts into the openings of the end faces of the first and second limiting parts on the moving mold, completing the first abutting positioning. S2. The first die-casting plate continues to move with the robotic arm and abuts against the end face of the moving mold. Due to the clearance fit between the positioning rod and the second die-casting plate, the continuous movement of the first die-casting plate drives the damping spring on the outside of the positioning rod to compress. S3. During the compression of the damping spring, a secondary thrust is released, which drives the second die-cast plate to continue moving along the positioning rod direction, thereby driving the abutment part to apply continuous pressure to the single-sided material strip, so that the single-sided material strip is tightly abutted with the opening end face of the first restriction part and the second restriction part, completing the second abutment calibration.

[0020] In summary, this application includes at least the following beneficial technical effects: By setting up a pre-compression unit and embedding multiple abutting parts, the U-shaped groove of the single-sided strip can be guaranteed to be processed to meet the requirements after mold opening. This avoids the angle deviation of the U-shaped groove due to strip offset after subsequent injection molding from the source, eliminating the need to rely on mold closing for correction.

[0021] By setting up an auxiliary demolding unit, each adsorption part can act specifically on the corresponding single-sided strip workpiece, ensuring that each workpiece on the continuous single-sided strip can be stably adsorbed. This avoids problems such as missed adsorption and multiple workpieces being adsorbed together due to the mismatch between the spacing of the adsorption parts and the spacing of the workpieces. At the same time, it avoids the situation where the unadsorbed single-sided strip is pulled and damaged due to its attachment to the first and second limiting parts when only a few single-sided strips are adsorbed, thus ensuring the orderliness of the demolding process.

[0022] By setting up an auxiliary unloading unit, it is ensured that the single-sided strip is always under the dual constraint of sliding positioning and rotating conveying when passing through, avoiding tilting of the single-sided strip due to posture deviation, thereby eliminating the generation of two bending points and preventing bending damage of continuous single-sided strips after demolding.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] Please see Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The present invention provides the following technical solutions: Example 1: To address the following problems in the prior art: When processing the single-sided strip 11 used to produce the single-sided strip 11 rows, because the single-sided strip 11 is only connected to the carrier on one side, its stability is poor. After injection molding, the formed U-shaped groove is prone to angular deviation due to the shaking of the single-sided strip 11. If the deviation is corrected by re-closing the mold, the mold closing force is large, which can easily damage the unstable U-shaped groove, thus causing the batch of products to be unqualified.

[0027] The system includes an injection molding machine 1, a robotic arm 2 mounted on the injection molding machine 1, and a moving mold 3 and a stationary mold 4 mounted on the injection molding machine 1. It also includes a pre-pressing unit 5, an auxiliary demolding unit 6, and an auxiliary unloading unit 7. The pre-pressing unit 5 is located at the top of the robotic arm 2 and includes abutment portions 51. Multiple abutment portions 51 are used to abut against the single-sided material strip 11 to be processed. Multiple abutment portions 51 are provided, and when the robotic arm 2 moves the pre-pressing unit 5 towards the moving mold 3, the multiple abutment portions 51 can engage with the single-sided material strip 11 to be embedded. The end face of 1 forms an abutment to pre-press and position the single-sided strip 11; the auxiliary demolding unit 6 is provided on the first die-casting plate 52, and the auxiliary demolding unit 6 is used to adsorb the injection molding surface of the single-sided strip 11 after pre-pressing and positioning to achieve auxiliary demolding of the single-sided strip 11; the auxiliary unloading unit 7 is used to clamp the single-sided strip 11 after adsorption and demolding, and drive the single-sided strip 11 to move along a preset direction so that the single-sided strip 11 in the adsorption state and the moving mold 3 maintain a parallel posture, so as to facilitate subsequent unloading.

[0028] In this embodiment, the single-sided material strip 11 is different from the double-sided material strip in the prior art. The single-sided material strip 11 has only one side as a connecting carrier, and the single-sided material strip 11 is applied to the base station after production.

[0029] In addition, a single-sided material belt 11 conveyor is provided on the side of the injection molding machine 1 for continuous conveying of the single-sided material belt 11, which is a top-down conveying direction that moves downward along the top of the moving mold 3.

[0030] The robotic arm 2 is started, driving the pre-compression unit 5 on its top to move towards the moving mold 3. As the pre-compression unit 5 moves, multiple abutting parts 51 simultaneously approach the single-sided strip 11 to be embedded with the terminal and form abutment with the end face of the single-sided strip 11. Through the abutting and embedding of multiple abutting parts 51, the U-shaped groove of the single-sided strip 11 can be guaranteed to be qualified after the mold is opened. This avoids the angle deviation of the U-shaped groove due to the strip offset after subsequent injection molding from the source, without the need to rely on the mold closing again for correction.

[0031] See Figure 5The pre-compression unit 5 includes a first die-casting plate 52 and a second die-casting plate 53; the first die-casting plate 52 is fixedly mounted on the working end of the robotic arm 2; the second die-casting plate 53 is slidably mounted on the side of the first die-casting plate 52, and the side of the second die-casting plate 53 is fixedly mounted with a plurality of abutment parts 51. When the first die-casting plate 52 and the second die-casting plate 53 move, they can drive the plurality of abutment parts 51 to move synchronously.

[0032] After the moving mold 3 and the stationary mold 4 are demolded, the angle of the U-shaped groove at the end face of the single-sided strip 11 is deviated in this state. At this time, the robotic arm 2 starts and drives the first die-casting plate 52, the second die-casting plate 53 and the abutment part 51 connected to it to move towards the moving mold 3. After moving, the abutment part 51 on the second die-casting plate 53 will press the U-shaped groove of the single-sided strip on the moving mold 3 to be embedded. After pressing, the single-sided strip 11 can be stably embedded, ensuring the pass rate of the single-sided strip.

[0033] See Figure 5 , Figure 7 and Figure 8 The pre-pressing unit 5 also includes positioning rods 54, damping springs 55, first limiting parts 56 and second limiting parts 57; multiple positioning rods 54 are respectively disposed on the side of the first die-casting plate 52, and the multiple positioning rods 54 are respectively clearance-fitted with the second die-casting plate 53; the damping springs 55 are disposed on the outside of the positioning rods 54, one end of the damping springs 55 is fixed to the end face of the first die-casting plate 52, and the other end of the damping springs 55 is fixed to the end face of the second die-casting plate 53; multiple first limiting parts 56 are respectively disposed on the moving mold 3; multiple second limiting parts 57 are respectively disposed on the moving mold 3, and the end faces of the first limiting parts 56 and the second limiting parts 57 are all provided with openings facing the stationary mold 4, and the openings are used to abut against the single-sided material strip 11.

[0034] In this embodiment, after the first die-casting plate 52 pushes the second die-casting plate 53 and the abutment part 51 to move towards the single-sided strip 11, the single-sided strip 11 is initially abutted and positioned by the abutment part 51. Subsequently, the abutment part 51 on the second die-casting plate 53 drives the single-sided strip 11 to gradually embed into the openings of the end faces of the first limiting part 56 and the second limiting part 57 on the moving mold 3, completing one embedding and positioning. In this state, the first die-casting plate 52 continues to move with the robotic arm 2 and abuts against the end face of the moving mold 3. Since the robotic arm 2 maintains its moving trend, its driving force will cause the damping spring 55 on the outside of the positioning rod 54 to compress. During the compression process, the damping spring 55 releases a secondary thrust, driving the second die-casting plate 53 to continue moving towards the moving mold 3, thereby pushing the abutment part 51 to continuously apply pressure to the single-sided strip 11, so that the single-sided strip 11 is tightly abutted against the opening end faces of the first limiting part 56 and the second limiting part 57, realizing a secondary embedding calibration. The elastic buffer and secondary thrust of the damping spring 55 not only correct the angular deviation of the U-shaped groove of the single-sided material strip 11, but also ensure that the single-sided material strip 11 is stably attached to the limiting part, thus avoiding displacement during subsequent conveying.

[0035] In the second embodiment, there is a technical defect in the unloading process of the single-sided strip 11 that leads to product bending damage and batch non-conformity: after the moving mold 3 and the stationary mold 4 are opened, cooling water needs to be sprayed onto the single-sided strip 11 on the moving mold 3 to cool it down. After cooling down, the abutment part 51 performs embedded bonding and positioning of the single-sided strip 11; after the robotic arm 2 drives the second die-casting plate 53 and the abutment part 51 away from the moving mold 3.

[0036] Due to friction, the contact surfaces of the single-sided strip 11 with the first limiting part 56 and the second limiting part 57 are coated with a water film formed by residual cooling water, resulting in partial adsorption between some of the single-sided strip 11 and the limiting parts. The single-sided strip 11 differs from the double-sided single-sided strip 11 in that it lacks a symmetrical and stable adsorption surface. Traditional vacuum adsorption mechanisms have difficulty finding a suitable adsorption area. If the adsorption position covers the U-shaped groove, it is easy to squeeze the groove wall and cause deformation. If the edge of the single-sided strip 11 is adsorbed, due to insufficient contact area, uneven force on one side is easy to occur during adsorption, which in turn causes some single-sided strips 11 to bend and be damaged during unloading, ultimately resulting in the batch of products being unqualified.

[0037] See Figure 10 The auxiliary demolding unit 6 includes a vacuum pump 61, a sealing box 62, and an adsorption unit 63. The vacuum pump 61 is disposed on the first die-casting plate 52. The sealing box 62 is disposed on the side of the first die-casting plate 52 and is connected to the vacuum pump 61 through a telescopic tube. There are multiple adsorption units 63, which are disposed on the first die-casting plate 52 respectively. The adsorption ends of the multiple adsorption units 63 are respectively facing the middle of the single-sided material strip 11, and the multiple adsorption units 63 are respectively connected to the sealing box 62.

[0038] In this embodiment, the telescopic tube is a stainless steel telescopic connecting sleeve in the prior art, which can adaptively expand and contract with the movement of the first die-cast plate 52, avoiding the tube body from being pulled or bent.

[0039] See Figure 11 , Figure 11 The figure shows a schematic diagram of the specific structure between the single-sided material strip 11 and the adsorption part 63 in the separated state. In this figure, the adsorption end of the adsorption part 63 corresponds to the injection molded part position in the middle of the single-sided material strip 11.

[0040] The vacuum pump 61, mounted on the first die-casting plate 52, is activated. The vacuum pump 61 evacuates the sealing box 62 via a telescopic tube connected to it, creating a stable negative pressure inside the sealing box 62. Simultaneously, multiple adsorption units 63 connected to the sealing box 62 apply negative pressure. Because the adsorption ends of the adsorption units 63 face the center of the single-sided material strip 11, they avoid the U-shaped groove area. Under this negative pressure, the adsorption ends tightly adhere to the center of the single-sided material strip 11. The adsorption units 63 apply adsorption force to the injection molded part in the center of the single-sided material strip 11, overcoming the adsorption resistance between the single-sided material strip 11 and the first and second limiting parts 56 and 57. The robotic arm 2 moves the first die-casting plate 52 and the second die-casting plate 53 away from the moving mold 3, smoothly disengaging the single-sided material strip 11 from the limiting parts. Once the single-sided material strip 11 reaches the unloading station, the vacuum pump 61 stops working, and the adsorption ends release the single-sided material strip 11, completing demolding without bending damage.

[0041] See Figure 10 Multiple adsorption sections 63 are evenly distributed along the conveying direction of the single-sided material belt 11, and the spacing between adjacent adsorption sections 63 is adapted to the workpiece spacing of the single-sided material belt 11.

[0042] In this embodiment, multiple adsorption parts 63 are evenly distributed along the conveying direction of the single-sided material strip 11, and the spacing between adjacent adsorption parts 63 is adapted to the workpiece spacing of the single-sided material strip 11. During operation: when the single-sided material strip 11 moves along the direction of the moving mold 3 with the conveying mechanism, the adsorption parts 63 evenly distributed along the conveying direction can directly correspond one-to-one with the individual single-sided material strip 11 on the single-sided material strip 11, and alignment can be achieved without additional adjustment of the position of the adsorption parts 63; then, when the negative pressure adsorption is started by the vacuum pump 61, each adsorption part 63 can act specifically on the corresponding single-sided material strip 11 workpiece, ensuring that each workpiece on the continuous single-sided material strip 11 can be stably adsorbed, avoiding the problem of missed adsorption and multiple workpieces being adsorbed due to the mismatch between the spacing of the adsorption parts 63 and the workpiece spacing, and at the same time avoiding the situation where the unadsorbed single-sided material strip 11 is pulled and damaged due to attachment to the first limiting part 56 and the second limiting part 57 when only a few single-sided material strips 11 are adsorbed, thus ensuring the orderliness of the demolding process.

[0043] See Figure 11The adsorption end of the adsorption part 63 is a circular bonding surface, and the diameter of the circular bonding surface is consistent with the diameter of the middle end face of the injection molded part of the single-sided strip 11.

[0044] The circular contact surface of the adsorption part 63 can be contacted with the inner arc surface of the middle part of the single-sided material strip 11 injection molded part to ensure that the negative pressure is stably applied between the adsorption end and the injection molded part.

[0045] In Example 3, to address the problems in the prior art, the auxiliary unloading unit 7 located at the bottom of the injection molding machine 1 mostly clamps the outer side of the single-sided strip 11, and then moves it, so that the single-sided strip 11 is continuously processed from top to bottom along the parallel plane of the moving mold 3. However, this results in the auxiliary unloading unit 7 at the bottom failing to move in the same direction as the single-sided strip 11 when it is attracted by the auxiliary demolding unit 6 and moves away from the moving mold 3, causing the single-sided strip 11 to exhibit an inclined state along the distance between the auxiliary demolding unit 6 and the auxiliary unloading unit 7. This tilted state will cause two bending points to be formed between the single-sided strip 11 and the auxiliary unloading unit 7 and the auxiliary demolding unit 6, which may lead to bending between multiple continuous single-sided strips 11, resulting in the single-sided strip 11 being unqualified in processing.

[0046] See Figure 12 The auxiliary unloading unit 7 includes a mounting frame 71, a first rotating part 72, and a second rotating part 73. The mounting frame 71 is slidably disposed at the bottom of the injection molding machine 1. The first rotating part 72 is rotatably disposed on the mounting frame 71. The second rotating part 73 is rotatably disposed on the first rotating part 72. A reserved space is left between the first rotating part 72 and the second rotating part 73 for the single-sided material strip 11 to pass through.

[0047] In this embodiment, the first rotating part 72 and the second rotating part 73 are preferably rubber wheels, which can increase the contact friction with the single-sided material strip 11 and prevent slippage during conveying. When the single-sided material strip 11 moves with the auxiliary demolding unit 6, the mounting frame 71 can slide along the bottom of the injection molding machine 1 to initially adapt to the moving direction of the demolding unit. At the same time, the first rotating part 72 and the second rotating part 73 abut against and convey the demolded single-sided material strip 11 through their own rotation. The space reserved between the two for the single-sided material strip 11 to pass through can ensure that the single-sided material strip 11 is always in a dual constraint state of sliding positioning and rotational conveying when passing through, avoiding tilting of the single-sided material strip 11 due to posture deviation, thereby eliminating the generation of two bending points and preventing bending damage of the continuous single-sided material strip 11 after demolding.

[0048] See Figure 12The auxiliary unloading unit 7 also includes a first rotary driver 74 and a fixing part 75; the first rotary driver 74 is disposed on the side of the first rotating part 72, and the output end of the first rotary driver 74 is connected to the input end of the first rotating part 72. When the first rotary driver 74 is started, it can drive the first rotating part 72 to rotate; the fixing part 75 has a pair and is disposed on the side of the mounting bracket 71, and the pair of fixing parts 75 are respectively located below the first rotating part 72 and the second rotating part 73, and an opening is left between the pair of fixing parts 75 for the single-sided material belt 11 to pass through.

[0049] When the auxiliary demolding unit 6 drives the single-sided strip 11 to move away from the moving mold 3, the first rotary driver 74, which is located next to the first rotary part 72, is activated. The output end of the first rotary driver 74 drives the first rotary part 72 to rotate actively, so that the first rotary part 72 can synchronously abut and convey the contacting single-sided strip 11. When the single-sided strip 11 is abutted and conveyed by the first rotary part 72 and the second rotary part 73, the second rotary part 73 can be passively driven to rotate by the single-sided strip 11. The reserved space between the two can keep the single-sided strip 11 passing smoothly. After conveying, the single-sided strip 11 passes through the reserved opening between a pair of fixed parts 75, ensuring that the single-sided strip 11 always maintains a horizontal posture between the auxiliary demolding unit 6 and the auxiliary unloading unit 7.

[0050] See Figure 12 The auxiliary unloading unit 7 also includes a positioning frame 76, a linear sliding part 77, and a linear motor 78. The positioning frame 76 is located at the bottom of the injection molding machine 1, and the top of the positioning frame 76 has a stroke chamber for the mounting frame 71 to slide. The linear sliding part 77 is slidably located at the bottom of the positioning frame 76, and the top of the linear sliding part 77 is fixedly connected to the mounting frame 71. The linear motor 78 is located on the side of the positioning frame 76, and the output end of the linear motor 78 is provided with a screw threadedly connected to the linear sliding part 77. When the linear motor 78 is started, it can drive the linear sliding part 77 and the mounting frame 71 to move along the stroke chamber at the top of the positioning frame 76 through the screw.

[0051] In this embodiment, the linear motor 78 is preferably a servo motor. When the auxiliary demolding unit 6 picks up the single-sided strip 11 and moves linearly away from the moving mold 3, the linear motor 78, which is located next to the positioning frame 76, is activated. The output end of the linear motor 78 drives the screw to rotate. Since the screw is threadedly connected to the linear sliding part 77, the rotation of the screw drives the linear sliding part 77 to slide along the bottom of the positioning frame 76. Since the top of the linear sliding part 77 is fixedly connected to the mounting frame 71, and the mounting frame 71 can slide in the stroke cavity at the top of the positioning frame 76, the linear sliding part 77 drives the mounting frame 71 to move linearly along the stroke cavity in sync with the auxiliary demolding unit 6 and match the moving distance of the auxiliary demolding unit 6, thereby avoiding bending damage to the continuous single-sided strip 11 and ensuring the processing qualification rate.

[0052] A terminal embedding process, using the terminal embedding device for a single-sided continuous strip as described above, includes the following steps: S1. The robotic arm 2 starts, driving the first die-casting plate 52 fixedly connected, the second die-casting plate 53 slidably disposed next to the first die-casting plate 52, and multiple abutting parts 51 on the second die-casting plate 53 to move towards the moving mold 3; during the movement, the abutting parts 51 are embedded into the U-shaped groove area of ​​the single-sided material strip 11, and at the same time, the single-sided material strip 11 initially abuts into the openings of the end faces of the first limiting part 56 and the second limiting part 57 on the moving mold 3, completing the first abutting positioning; S2. The first die-casting plate 52 continues to move with the robotic arm 2 and abuts against the end face of the moving mold 3. Due to the clearance fit between the positioning rod 54 and the second die-casting plate 53, the continuous movement of the first die-casting plate 52 drives the damping spring 55 on the outside of the positioning rod 54 to compress. S3, the damping spring 55 releases secondary thrust during compression, driving the second die-cast plate 53 to continue moving along the positioning rod 54, thereby driving the abutment part 51 to apply continuous pressure to the single-sided material strip 11, so that the single-sided material strip 11 is tightly abutted with the opening end face of the first limiting part 56 and the second limiting part 57, completing the second abutment calibration.

[0053] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
