Description

Technical Field

[0001] This invention relates to the field of new energy vehicles, and in particular to a connecting piece forming device. Background Technology

[0002] Against the backdrop of the rapid development of the new energy vehicle industry, the ease of assembly and stability of vehicle wiring harnesses directly affect the operational quality of the entire vehicle's electrical system. Connectors, as core components for wiring harness connections, are mainly used to integrate the ends of multiple connecting wires, enabling rapid connection and disconnection of the wiring harness. They are indispensable basic components in the electrical architecture of new energy vehicles. Currently, mainstream connectors in the industry adopt a composite structure of metal and plastic parts, balancing conductivity, insulation protection, and assembly compatibility, and are widely used in various vehicle wiring harness assemblies.

[0003] Currently, the standardized molding process for connecting pieces consists of two core steps. First, a progressive die is used to continuously stamp the conductive metal substrate. Then, the formed metal parts are neatly arranged and injection molded together with the plastic parts. Among these, the progressive die stamping process has the advantages of high molding efficiency, stable precision, and suitability for mass production. It can quickly complete integrated processing such as shaping, punching, and bending of metal parts, meeting the basic requirements for large-scale production of new energy vehicle components. It is a commonly used and efficient processing method in the industry.

[0004] However, this process has significant technical shortcomings. After the progressive die stamping is completed, the metal parts fall into the blanking frame in a disordered and chaotic state, without a fixed arrangement pattern, and cannot directly enter the subsequent composite process. This requires manual sorting, organizing, and aligning of the scattered metal parts one by one, which not only significantly increases labor costs but also greatly extends the overall production process time. Manual sorting is inefficient and inconsistent, and is prone to placement deviations and missed defects, indirectly affecting the product qualification rate of subsequent composite molding.

[0005] In summary, how to achieve rapid prototyping of connecting pieces and improve their prototyping efficiency has become an urgent problem for researchers in this field. Summary of the Invention

The conveying channel is equipped with a sprue removal component, which removes the sprues from the first plastic part and the second plastic part in the first semi-finished product to form the second semi-finished product. On the conveying channel, and behind the sprue cutting assembly, a first cutting assembly is provided. The first cutting assembly is used to cut off the first connecting part on the side of the second semi-finished product and the second connecting part connecting adjacent legs in the second semi-finished product to form a third semi-finished product. A second cutting component is provided on the conveying channel and behind the sprue cutting component. The second cutting component is used to separate the channel from the third semi-finished product to form a connecting piece.

[0008] Furthermore, the drive assembly includes rotating wheels rotatably disposed on both sides of the bottom of the conveyor channel. The rotating wheels are provided with circumferentially protruding teeth that can cooperate with the drive holes on the material belt.

The downward pressure cylinder drives the lifting block, together with the cutting rod and the guide rod, to move downward. While the cutting rod cuts off the sprues of the first and second plastic parts, the guide rod passes through the drive hole on the material belt and inserts its end into the positioning hole on the conveyor channel.

[0010] Furthermore, the bottom of the guide block is provided with a first clearance groove along its length to avoid the first plastic part and the second plastic part.

[0011] Furthermore, the first cutting component includes: a first bracket, which is fixedly connected to the conveying channel, and a first cylinder is fixed on the first bracket; the output end of the first cylinder, and a first pressing block is provided inside the first bracket, a first pre-pressing block is suspended at the bottom of the first pressing block, and a first cutting rod and a second cutting rod are movably arranged on the first pre-pressing block; The first cylinder drives the first pre-compression block to pre-compress on the conveying channel once. The first cylinder drives the first pressing block to descend a second time and acts on the top of the first cutting rod and the second cutting rod. At the same time, the bottom end of the first cutting rod acts on the first connecting part to cut, and the bottom end of the second cutting rod acts on the second connecting part to cut.

[0017] Furthermore, a collection box is provided at the end of the conveying channel. The collection box is connected to the conveying channel through a conveying pipe. A clamping block is provided at the end of the conveying channel to press the channel. A liftable cutter is provided on one side of the clamping block.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0022] See Figure 1 This is a connection diagram of strip 100 and multiple first semi-finished products 01. Strip 100 and first semi-finished products 01 are stamped into metal parts through a previous stamping process. Through injection molding, first plastic parts 110 and second plastic parts 120 are injection molded on corresponding metal sheets. Therefore, the first semi-finished product 01 in the figure is provided with first plastic parts 110 and second plastic parts 120. Both plastic parts have sprue 130. Adjacent first semi-finished products 01 are connected by first connecting parts 140. The first semi-finished product 01 is provided with support legs 011. Support legs 011 are connected by second connecting parts 150. The second connecting parts 150 can ensure that the support legs 011 of the first semi-finished product 01 do not bend during the stamping process of the metal parts. See Figure 2 This is a connection diagram of material channel 100 and multiple second semi-finished products 02. Figure 1 The difference is that both sprues 130 on the second semi-finished product 02 are cut off by the sprue cutting component 3; See Figure 3 This is a connection diagram of material channel 100 and multiple third semi-finished products 03, and... Figure 2 The difference is that the first connecting part 140 and the second connecting part 150 on the third semi-finished product 03 are both cut off by the first cutting component 1; See Figure 4 The diagram shows the connecting piece 04, which is cut by the second cutting component 2 to be separated from the material strip 100 in sequence.

[0023] See Figure 5 , 6This embodiment is a connecting piece forming device, which is used to finally form the first semi-finished product 01 on the material strip 100 into the connecting piece 04. It includes a conveying channel 10, and a sinking groove 101 is formed on the upper surface of the conveying channel 10 extending downward along its length. The material strip 100 is placed on the conveying channel 10 with the first semi-finished product 01 connected to it. The bottoms of the first plastic part 110 and the second plastic part 120 are located at the sinking groove 101, so that the first semi-finished product 01 is horizontal. The conveying channel 10 is arranged from left to right as a sprue cutting component 3, a first cutting component 1, and a second cutting component 2. In this embodiment, the first semi-finished product 01 is sequentially cut by the sprue cutting component 3, the first cutting component 1, and the second cutting component 2 to form a connecting piece 04. The connecting piece 04 can be collected in an orderly manner, which realizes the rapid forming of the connecting piece 04 and improves the forming efficiency.

[0024] See Figure 7 , 8 9. In some possible embodiments, in order to realize the material belt 100 connecting the corresponding half-length product and conveying it along the length direction of the conveying channel 10, this embodiment adopts the drive assembly including rotating wheels 5 rotatably disposed on both sides of the bottom of the conveying channel 10. The rotating wheels 5 are provided with actuating teeth 51 protruding in the circumferential direction, which can cooperate with the drive hole 160 on the material belt 100. The two rotating wheels 5 are connected by a synchronous belt 52, wherein the rotating wheels 5 are input with rotational force. In this embodiment, the material belt 100 has drive holes 160 at equal intervals along its length. The left rotating wheel 5 is connected to the motor, and the right rotating wheel 5 is connected to the left rotating wheel 5 through the synchronous belt 52. The actuating teeth 51 on the rotating wheel 5 pass through the long groove of the conveying channel 10 and can be inserted into the corresponding drive hole 160 of the material belt 100. The two rotating wheels 5 rotate clockwise to drive the material belt 100 to transport the corresponding semi-finished product to the right to the corresponding mechanism for cutting. By opening a drive hole 160 on the material belt 100, the drive hole 160 cooperates with the actuating tooth 51 on the rotating wheel 5 to drive the material belt 100 and the corresponding semi-finished product to perform stepping motion.

[0025] See Figure 10 , 1112. In some possible embodiments, the sprue removal assembly 3 includes: a sprue removal bracket 31, which is fixedly connected to the conveying channel 10; a guide block 32 is provided below the sprue removal bracket 31 and on the conveying channel 10; a lifting block 33 is provided on the top of the guide block 32, which is connected to a pressing cylinder 34 on the top of the sprue removal bracket 31; a cutting rod 35 and a guide rod 36 passing through the guide block 32 are provided at the bottom of the lifting block 33; the pressing cylinder 34 drives the lifting block 33 together with the cutting rod 35 and the guide rod 36 to move downwards; while the cutting rod 35 cuts the sprue 130 of the first plastic part 110 and the second plastic part 120 downwards, the guide rod 36 passes through the driving hole 160 on the material belt 100 and inserts its end into the positioning hole 102 on the conveying channel 10; In this embodiment, the guide block 32 is fixedly installed on the conveying channel 10. The function of the guide block 32 is to ensure that the guide rod 36 and the cutting rod 35 only move up and down during their movement. The lifting block 33 is controlled by the pressing cylinder 34 to descend and insert the guide rod 36 into the drive hole 160 to avoid inaccurate positioning of the first semi-finished product 01 when the sprue 130 is cut off. The lifting block 33 presses down the cutting rod 35. The bottom end of the cutting rod 35 protrudes from the bottom of the guide block 32 and acts on the sprue 130 of the first plastic part 110 and the second plastic part 120, so that the sprue 130 is pressed down and detached from the corresponding plastic part. It should also be noted that there are multiple guide rods 36, which not only mate with the positioning holes 102 on the material strip 100, but also mate with the holes on the first semi-finished product 01; Of course, a waste outlet is provided below the sprue 130 and on the conveying channel 10, which is used for the discharge of the sprue 130 after it has been cut off.

[0026] See Figure 10 In some possible embodiments, the bottom of the guide block 32 is provided with a first clearance groove 321 for avoiding the first plastic part 110 and the second plastic part 120 along its length direction; In this embodiment, when the first semi-finished product 01 is located between the conveying channel 10 and the guide block 32, the first semi-finished product 01 can be conveyed horizontally due to the setting of the first clearance groove 321, avoiding interference with the guide block 33.

[0027] See Figure 13 , 1415. In some possible embodiments, the first cutting assembly 1 includes: a first support 11, which is fixedly connected to the conveying channel 10, and a first cylinder 12 is fixed on the first support 11; the output end of the first cylinder 12, and a first pressing block 13 is provided in the first support 11, a first pre-pressing block 14 is suspended at the bottom of the first pressing block 13, and a first cutting rod 15 and a second cutting rod 16 are movably arranged on the first pre-pressing block 14; the first cylinder 12 drives the first pre-pressing block 14 to pre-press on the conveying channel 10 once downward, and the first cylinder 12 drives the first pressing block 13 downward and acts on the top of the first cutting rod 15 and the second cutting rod 16 a second time downward, so that the bottom end of the first cutting rod 15 acts on the first connecting part 140 for cutting, and the bottom end of the second cutting rod 16 acts on the second connecting part 150 for cutting.

[0028] In this embodiment, when the piston rod of the first cylinder 12 is in the retracted state, due to the suspension relationship between the first pre-pressing block 14 and the first lower pressing block 13, there is a gap between the first pre-pressing block 14 and the first lower pressing block 13, and the first cutting rod 15 and the second cutting rod 16 do not protrude from the bottom of the first pre-pressing block 14; when the piston rod of the first cylinder 12 is in the extended state, the first pre-pressing block 14 moves downward, and it presses the second semi-finished product 02 onto the conveying channel 10 by gravity. Then the first cylinder 12 extends again, pressing the first lower pressing block 13 onto the first pre-pressing block 14. At this time, the first cutting rod 15 and the second cutting rod 16 protrude from the bottom of the first pre-pressing block 14, and the ends of the first cutting rod 15 and the second cutting rod 16 cut at the first connecting part 140 and the second connecting part 150. Of course, a waste discharge port is also provided on the conveying channel 10 and below the first connecting part 140 and the second connecting part 150 for discharging the first connecting part 140 and the second connecting part 150 after they are cut off.

[0029] See Figure 14 In some possible embodiments, the bottom of the first cutting rod 15 is a stepped structure 151, and the bottom of the second cutting rod 16 is a toothed stepped structure 161. In this embodiment, the area of ​​the waste discharge port is larger than the bottom area of ​​the first cutting rod 15 and the second cutting rod 16, so that the first cutting rod 15 can pass through the second semi-finished product 02 and the stepped surface of the bottom stepped structure 151 of the first cutting rod 15 is pressed down and punched with the first connecting part 140; similarly, the stepped surface of the bottom toothed stepped structure 161 of the second cutting rod 16 is pressed down and punched with the second connecting part 150, and the connected second semi-finished product 02 is punched until the third semi-finished product 03 is only connected to the material channel 100.

[0030] See Figure 16 , 1718. In some possible embodiments, the second cutting assembly 2 includes a pressure plate 21 fixed to the side of the conveying channel 10 for pressing the material belt 100; a second support platform 25 is provided on the conveying channel 10, and a liftable second cutting platform 22 is provided at the center of the second support platform 25; a second lifting block 24 controlled by a second cylinder 23 is provided at the bottom of the conveying channel 10, and the bottom of the second cutting platform 22 abuts against the second lifting block 24; the second cylinder 23 drives the second lifting block 24 to rise, so that the second cutting platform 22 protrudes from the top of the second lifting platform 25, and the third semi-finished product 03 is lifted and separated from the channel 100; In this embodiment, when the third semi-finished product 03 moves to the second cutting component 2, it is supported on the second support platform 25, and the material strip 100 is located between the pressure plate 21 and the conveying channel 10. At this time, the second cylinder 23 rises once, and under the drive of the second lifting block 24, the second cutting table 22 protrudes from the top of the second support platform 25, cutting the third semi-finished product 03 to separate it from the material strip 100, forming a connecting piece 04.

[0031] See Figure 19 In some possible embodiments, a positioning rod 26 is provided inside the second support platform 25. The bottom of the positioning rod 26 abuts against the second lifting block 24. The positioning rod 26 can be driven by the second cylinder 23 to pass through the drive hole 160 of the material channel 100 and place its top end in the positioning hole 211 opened in the pressure plate 21. In this embodiment, the second cylinder 23 can drive the second lifting platform 24 to rise while passing the positioning rod 26 through the drive hole 160 of the material strip 100 and positioning the end of the positioning rod 26 in the positioning hole 211 opened at the bottom of the pressure plate 21. In this way, before the third semi-finished product 03 is separated from the material strip 100, the positioning rod 211 is used to cooperate with the drive hole 160 to position the material strip 100. It should be added that after the connecting piece 04 is formed, a pickup component is provided above the connecting piece 04. The pickup component picks up the connecting piece 04 and performs subsequent electrical testing.

[0032] See Figure 20 , 2122. In some possible embodiments, the first cutting component 1 and the second cutting component 2 are connected, and a detection module 6 is provided on the conveying channel 10. A full-cutting component 4 is provided between the detection module 6 and the second cutting component 2. The full-cutting component 4 includes: a full-cutting bracket 41, which is fixedly connected to the conveying channel 10, and a third cylinder 42 is fixed on the full-cutting bracket 41. The output end of the third cylinder 42 is provided, and a third pressing block 43 is provided inside the full-cutting bracket 41. The bottom of the third pressing block 43 is connected to the full-cutting block 44. A third guide block 45 is fixed on the conveying channel 10, and the full-cutting block 44 is vertically and vertically arranged inside the guide block 45. The third cylinder 42 drives the third pressing block 43 and the full cutting block 44 to move downward, so that the bottom of the full cutting block 44 protrudes from the third guide block 45, separating the third semi-finished product 03 from the material channel 100. In this embodiment, after the first cutting component 1 completes the punching of the first connecting part 140 and the second connecting part 150, the CCD detection module 6 detects the third semi-finished product 03 to check whether there is dirt, burrs or dents on its surface. If the detection fails, it is judged as a defective bottle. The third semi-finished product 03 moves to the full punching component 4. The full punching component 4 separates the defective third semi-finished product 03 from the material strip 100 in advance. The piston rod in the third cylinder 42 in the full punching component 4 works to lower the full punching block 44 until its bottom protrudes from the bottom of the third guide block 45, so that the third semi-finished product 03 is separated from the material channel 100. It should be added that the bottom of the third pressing block 43 is connected to a positioning rod 46, and the positioning rod 46 passes through the third guide block 45. It can cooperate with the drive hole 160 on the material belt 100 to position the material belt 100 together with the third semi-finished product 03 on the conveying channel 10.

[0033] See Figure 23 In some possible embodiments, a collection box 7 is provided at the end of the conveying channel 10. The collection box 7 is connected to the conveying channel 10 by an inclined conveying pipe 71. A pressing block 72 is provided at the end of the conveying channel 71 to press the material belt 10. A liftable cutter 73 is provided on one side of the pressing block 72. The cutter 73 is controlled to lift by a fourth cylinder 74 to cut the long strip of material belt 100 into short segments and collect them in the collection box 7. In this embodiment, the fourth cylinder 74 drives the cutter 73 to rise relative to the clamping block 72, cutting the material strip 100 into short segments, which then enter the collection box 7 through the conveying pipe 71 for collection.

[0034] It should be emphasized that the processes in this solution cannot be interchanged. For example, if the gate cutting component 3 and the first cutting component 1 are interchanged, the first connecting part 140 and the second connecting part 150 are cut first, and then the gate 150 is cut. Because the shape of the gate 150 is not fixed, when cutting the first connecting part 140 and the second connecting part 150, the shape of the gate 150 will cause the semi-finished product to be inaccurately positioned during punching.

[0035] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept.
