Description

Technical Field

[0001] This invention relates to the field of wire harness assembly machine technology, and in particular to a fully automatic terminal crimping machine that punctures one side and presses the other side. Background Technology

[0002] In the production process of wire harnesses, the wires need to be stripped, crimped with terminals, and then inserted into a housing to fix the ends of the wires to the housing. Existing technology can already automate the processes of housing feeding, wire storage, wire stripping, terminal crimping, and terminal piercing on a single machine. For example, CN202310872480.X discloses a fully automatic machine for piercing two terminals on one side and crimping the other side. This machine uses a housing feeding assembly to feed the housing to the terminal piercing assembly. In this application, the working principle of the housing feeding assembly is to feed the stored housing... The material box is placed horizontally, and an air blowing device is installed at the end of the material box to move the plastic shell in the material box horizontally and transport it to the terminal piercing assembly. Then, the material box is pushed up by a device set in the vertical direction to move several stacked material boxes upward to realize automatic material changing. However, since the material box has a certain length, the plastic shells will collide with each other under the blowing of the air blowing device, making it difficult to keep the material supply to the terminal piercing assembly smooth. In addition, this setting means that the production line needs to have a certain length in the horizontal direction, which is not conducive to compressing the length of the production line. Summary of the Invention

[0003] The purpose of this invention is to provide a fully automatic terminal crimping machine that punctures one side and presses the other side, in order to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] First, this invention provides a fully automatic terminal crimping machine for single-sided piercing and other-sided pressing, comprising a glue shell feeding assembly, a terminal crimping assembly, and a machine base. Both the glue shell feeding assembly and the terminal crimping assembly are fixedly connected to the machine base. A glue shell conveying track is provided between the glue shell feeding assembly and the terminal crimping assembly. With the length extension direction of the machine base as the X-axis and the width extension direction of the machine base as the Y-axis, both the glue shell feeding assembly and the terminal crimping assembly are distributed along the X-axis. The glue shell feeding assembly includes:

[0006] A feeding rack moving mechanism is connected to the machine base. The feeding rack moving mechanism is provided with a first driving mechanism and a first track extending along the Y-axis.

[0007] The feeding rack has a plastic shell passage at the bottom. The side wall of the feeding rack is slidably connected to the first track and connected to the power output end of the first drive mechanism. The first drive mechanism drives the feeding rack to move along the Y-axis.

[0008] A material tray, which is connected to the feeding rack, includes at least one supply channel for supplying rubber shells extending along the Z-axis;

[0009] A plastic shell transfer mechanism is provided below the feeding rack and connected to the machine base. The plastic shell transfer mechanism partially blocks the plastic shell through an opening to form a first discharge port. The plastic shell transfer mechanism includes a second drive mechanism and a transfer plate connected to the second drive mechanism. The transfer plate has a transfer channel, one end of which is a first feed port. The plastic shell in the feeding channel falls into the transfer channel through the first feed port. The other end of the transfer channel is connected to a third drive mechanism. The second drive mechanism drives the transfer plate to rotate, causing the first feed port to rotate between the entrance end of the plastic shell conveying track and the first discharge port. The third drive mechanism moves the plastic shell in the transfer channel toward the entrance end of the plastic shell conveying track.

[0010] Workflow: Initially, the plastic shell in the tray falls downward into the transfer channel. Then, the second drive mechanism drives the transfer tray to rotate, which in turn drives the transfer channel to rotate, connecting the first inlet with the plastic shell conveying track. Subsequently, the third drive mechanism moves the plastic shell towards the plastic shell conveying track, facilitating processing by the terminal piercing component. Then, the third drive mechanism stops working, and the second drive mechanism drives the transfer tray to rotate back, causing the plastic shell to fall into the transfer channel again. This process is repeated.

[0011] Generally, the material tray includes multiple supply channels arranged along the Y-axis. When all the plastic shells in a supply channel are used up, the feeding rack moving mechanism drives the feeding rack to move in the Y-axis direction. The feeding rack moving mechanism of the subsequent supply channel undergoes relative displacement, so that the subsequent supply channel is no longer blocked, and the plastic shells in the subsequent supply channel can continue to be fed. The first driving mechanism drives the feeding rack to move along the Y-axis to realize the function of automatic material changing.

[0012] It is understood that the number of rubber shells falling into the transfer channel each time can be one or more, depending on the specific processing requirements. However, the number of rubber shells falling into the transfer channel each time is less than the number in the supply channel. Therefore, the diameter of the transfer plate can be set to be smaller. During the rotation of the transfer plate, the outer wall of the transfer plate abuts against the first discharge port to prevent the rubber shells from falling further.

[0013] In this solution, firstly, the plastic shell feeding assembly adopts a natural dropping method, allowing the plastic shell to fall into the transfer channel located on the transfer plate. Then, the third drive mechanism pushes the plastic shell onto the plastic shell conveying track, enabling the terminal piercing assembly to perform subsequent processing. This reduces collisions between plastic shells, and because the diameter of the transfer plate can be set to be smaller, the conveying distance is shortened, making the plastic shell discharge smoother.

[0014] Secondly, the arrangement of this solution makes better use of the space along the Z and Y axes, avoiding the arrangement of the feed box extending along the X axis as in the prior art, and can shorten the length of the production line while ensuring the amount of material supplied.

[0015] The number of rubber shells falling into the transfer channel each time can be controlled by setting the depth of the transfer channel or by controlling the rotation speed of the transfer disk.

[0016] As an extension of the above solution, a first air outlet nozzle is provided above the material tray. The first air outlet nozzle emits air vertically downwards, and the gas flows through the supply channel, passes through the first outlet, and then flows into the transfer channel. By setting the first air outlet nozzle to emit air downwards, the gas acts on the rubber shell as it falls due to its own weight, making the rubber shell fall into the transfer channel more smoothly. At this time, the output power of the gas can be set to be relatively small.

[0017] It should be explained that, in this solution, there are various ways to set the first air outlet nozzle above the material tray. One way is to set the first air outlet nozzle bracket on the first track. The first air outlet nozzle bracket includes a vertical arm extending along the Z-axis, a nozzle support arm extending along the X-axis, and a connecting seat. The nozzle support arm is connected to the vertical arm through the connecting seat. The first air outlet nozzle is set on the nozzle support arm, so the first air outlet nozzle can be located above the material tray. By adjusting the locking screw on the connecting seat, the first air outlet nozzle can slide along the X-axis and along the Z-axis, so that the first air outlet nozzle can be adapted to material trays of different lengths and is easy to adjust.

[0018] As an extension of the above solution, the third drive mechanism includes a second exhaust nozzle and a first intake pipe. The second exhaust nozzle is rotatably connected to the side wall of the transfer disk along the Y-axis. The exhaust end of the second exhaust nozzle extends into the transfer channel, and the intake end of the second exhaust nozzle is located outside the transfer channel and connected to a gas source through the first intake pipe. Since the weight of a single housing is extremely light, using gas as the drive source for the third drive mechanism has economic advantages. In this solution, the second exhaust nozzle is a rotary nozzle, which can rotate relative to the transfer disk. When the transfer disk rotates, the first intake pipe does not rotate with it. This design avoids the first intake pipe from loosening during long-term continuous rotation.

[0019] As an extension of the above solution, the third driving mechanism includes a slider and a sliding seat extending along the X-axis. The sliding seat is connected to the feeding rack moving mechanism. The sliding seat is provided with a slide rail. The slider is slidably connected to the slide rail. A push rod extending towards the transfer disk is connected to the slider. A through hole adapted to the push rod is provided at the bottom of the transfer channel. Both ends of the sliding seat on the X-axis are provided with third air nozzles. The air outlet end of the third air nozzle faces the slider. When the transfer disk rotates, the push rod can move into the transfer channel.

[0020] In this solution, by using a gas-driven slider to reciprocate along the X-axis, a push rod on the slider can extend into the transfer channel to push the rubber shell in the transfer channel onto the rubber shell conveying track, making the movement of the rubber shell more stable. It should be explained that there are several ways to move the push rod into the transfer channel. One method is that the bottom of the transfer channel, corresponding to the outer wall in the X-axis direction, has a through hole adapted to the push rod. When the transfer disk is not rotating, the push rod can be a certain distance from the outer wall of the transfer disk in the X-axis direction. When the transfer disk rotates, the position of the through hole changes accordingly, allowing the push rod to move towards the transfer disk, inserting into the transfer channel and pushing out the rubber shell.

[0021] The third air nozzles located at both ends of the X-axis of the sliding seat do not emit air simultaneously. When the slider needs to move towards the transfer disk, the third air nozzle furthest from the transfer disk emits air alone, causing the slider to move closer to the transfer disk. When the slider needs to move away from the transfer disk, the third air nozzle closest to the transfer disk emits air alone, driving the slider away from the transfer disk, thus achieving the reciprocating motion of the slider. Using gas to drive the slider's movement increases the slider's speed and has high economic benefits.

[0022] As an extension of the above solution, the slide block has wall plates at both ends in the X-axis direction, the slide rail is connected to the wall plates, and the third air nozzle is disposed on the wall plates. This arrangement allows the wall plates to limit the movement of the slider, and simplifies the placement of the third air nozzle, resulting in a simple structure and stable operation of the third drive mechanism.

[0023] As an extension of the above solution, a fourth drive mechanism and a transport gripper are provided on the machine base between the terminal piercing assembly and the shell feeding assembly. The fourth drive mechanism drives the transport gripper to move along the X and Y directions.

[0024] In this extended solution, the fourth driving mechanism drives the transport gripper to move along the X and Y axes. Initially, the transport gripper is positioned on the X-axis near the housing feeding assembly, blocking newly entering housings in the housing conveying track. When the transport gripper moves away from the housing conveying track on the Y-axis, the housing is fed into the housing conveying track corresponding to the fourth driving mechanism through the entrance end of the housing conveying track. Then, the transport gripper resets on the Y-axis towards the housing conveying track, and the fourth driving mechanism drives the transport gripper to move in the X-axis direction, moving the housing towards the terminal piercing assembly to achieve subsequent terminal piercing processing. Then, the transport gripper resets in the X-axis direction, repeating the above actions. This controls the number of housings entering the housing conveying track, ensuring a consistent number of housings entering the terminal piercing assembly.

[0025] In one embodiment of this extended solution, the fourth drive mechanism includes a second track extending along the X-axis, a slide block, a slide block drive source, a third track extending along the Y-axis, a slide plate, and a slide plate drive source. The second track extends from one end of the housing conveying track near the transfer tray toward the terminal piercing assembly. The third track is disposed on the slide block. The slide plate is slidably connected to the third track. The slide block is slidably connected to the second track. The second track is disposed on the side of the terminal piercing assembly away from the housing conveying track.

[0026] The transport gripper includes a gripper connecting plate extending along the Z-axis and a gripper extending along the Y-axis. The gripper connecting plate is connected to the side of the slide plate near the plastic shell conveying track. The gripper is connected to the side wall of the gripper connecting plate. The gripper is provided with two support arms extending along the Y-axis. The two support arms are arranged parallel in the X-axis direction. The two support arms are located between the surface of the plastic shell conveying track and the top of the plastic shell in the Z-axis direction. The power output end of the slide block drive source is connected to the slide block, causing the slide block to reciprocate relative to the second track along the X-axis direction. The power output end of the slide block drive source is connected to the slide block, driving the slide block to reciprocate relative to the third track along the Y-axis.

[0027] When a new plastic shell is ready to be transported from the transfer channel to the plastic shell transport track, the slide drive source drives the transport gripper to move towards the slide block, so that the gripper does not obstruct the plastic shell transport track. At this time, the plastic shell can be transported into the plastic shell transport track between the two grippers. Then, the slide drive source drives the slide to move towards the plastic shell transport track, so that the gripper obstructs the plastic shell transport track again. Subsequently, the slide drive source drives the slide block to slide towards the terminal piercing assembly, thereby realizing the transfer of the plastic shell.

[0028] As an extension of the above solution, there is a gap between the side of the transport gripper near the plastic shell feeding assembly and the entrance end of the plastic shell conveying track. This arrangement of the transport gripper helps to align the plastic shell before it enters the plastic shell conveying track, preventing the plastic shell from getting stuck at the entrance end of the plastic shell conveying track.

[0029] As an extension of the above solution, a foolproof cutting assembly connected to the machine tool is provided between the housing feeding assembly and the terminal piercing assembly. The foolproof cutting assembly includes a fifth drive mechanism and a cutter. The cutter is located above the housing conveying track, and the fifth drive mechanism drives the cutter to reciprocate up and down. During the process of the transport gripper moving the housing to the terminal piercing assembly, the cutter can cut the housing during transport. By setting the foolproof cutting assembly, foolproof cutting of the housing in the housing conveying track below the cutter can be achieved, eliminating the need for pre-cutting and improving production versatility.

[0030] As an extension of the above solution, a recycling pipe is provided on one side of the plastic shell conveying track corresponding to the foolproof structure cutting assembly. The opening of one end of the recycling pipe faces the plastic shell conveying track, and the other end of the recycling pipe is connected to a recycling device.

[0031] By configuring the recycling pipe with one end opening towards the conveying track of the rubber shell, when the cutter cuts the rubber shell, the generated waste enters the recycling device through the recycling pipe, avoiding interference with subsequent processing. Various types of recycling devices can be selected, one of which is a negative pressure device. By setting a negative pressure device, the cut debris is attracted into the recycling pipe, resulting in a simple structure and good cleaning effect.

[0032] As an extension of the above solution, a detection component is provided on the side of the terminal piercing component away from the plastic shell feeding component. The detection component includes an image acquisition device arranged along the Z-axis. The image acquisition device is electrically connected to an industrial control computer, and the acquisition area of ​​the image acquisition device is located above the plastic shell conveying track.

[0033] By setting up the detection component, the workpiece processed by the terminal puncture component can be inspected to detect the cutting quality of the foolproof structure of the shell.

[0034] Specifically, the transport gripper drives the workpiece, after being processed by the terminal piercing component, to continue moving along the plastic shell conveyor track. When the workpiece moves to below the detection component, the image acquisition device takes a picture of the workpiece and transmits the image back to the industrial control computer. The comparison software on the industrial control computer compares the captured image with a preset image to quickly determine whether the opening size of the plastic shell and the cut edge meet the requirements. If they meet the requirements, the transport gripper continues to move; if they do not meet the requirements, the non-compliant plastic shell is pushed out by an external removal mechanism. The fourth drive mechanism and the transport gripper can drive the plastic shell from the inlet end of the plastic shell conveyor track to below the detection component.

[0035] The fully automatic terminal crimping machine with single-sided piercing and other-sided pressing provided by this invention can complete the processes of wire stripping, terminal crimping, housing feeding, error-proof structure cutting, terminal piercing, and quality inspection in one machine. It can effectively reduce the length of the production line, improve the versatility of the housing, and increase production efficiency. The fully automatic terminal crimping machine with single-sided piercing and other-sided pressing provided by this invention belongs to the field of wire harness assembly machine technology and is applied to wire harness production.

[0048] Reference Figures 1 to 6 The following are several embodiments of the fully automatic terminal crimping machine for unilateral piercing and other-side pressing according to the present invention.

[0049] like Figures 1 to 6 As shown, a fully automatic terminal crimping machine that pierces one side and crimps the other includes:

[0050] The system includes a plastic shell feeding assembly 100, a terminal piercing assembly 200, and a machine base 300. Both the plastic shell feeding assembly 100 and the terminal piercing assembly 200 are fixedly connected to the machine base 300. A plastic shell conveying track 400 is provided between the plastic shell feeding assembly 100 and the terminal piercing assembly 200. The machine base 300 extends along its length (X-axis) and its width (Y-axis). Both the plastic shell feeding assembly 100 and the terminal piercing assembly 200 are distributed along the X-axis. The plastic shell feeding assembly 100 includes:

[0051] The feeding rack moving mechanism 101 is connected to the machine base 300. The feeding rack moving mechanism 101 is provided with a first driving mechanism 1011 and a first track 1012 extending along the Y-axis.

[0052] The feeding rack 102 has a plastic shell passage at the bottom. The side wall of the feeding rack 102 is slidably connected to the first track 1012 and connected to the power output end of the first drive mechanism 1011. The first drive mechanism 1011 drives the feeding rack 102 to move along the Y-axis.

[0053] Material tray 103, which is connected to the feeding rack 102, includes at least one supply channel for supplying rubber shells extending along the Z-axis;

[0054] A plastic shell transfer mechanism 104 is located below the feeding rack 102 and connected to the machine base 300. The plastic shell transfer mechanism 104 partially obstructs the plastic shell through the opening to form a first discharge port. The plastic shell transfer mechanism 104 includes a second drive mechanism 1041 and a transfer disk 1042 connected to the second drive mechanism 1041. The transfer disk 1042 has a transfer channel, one end of which is a first feed port 1043. The plastic shell in the feeding channel falls into the transfer channel through the first feed port 1043. The other end of the transfer channel is connected to a third drive mechanism 105. The second drive mechanism 1041 drives the transfer disk 1042 to rotate, causing the first feed port 1043 to rotate between the entrance end of the plastic shell conveying track 400 and the first discharge port. The third drive mechanism 105 causes the plastic shell in the transfer channel to move towards the entrance end of the plastic shell conveying track 400.

[0055] Workflow: Initially, the plastic shell in the tray falls downward into the transfer channel. Then, the second drive mechanism 1041 drives the transfer disk 1042 to rotate, causing the transfer channel to rotate, so that the first inlet is connected to the plastic shell conveying track 400. Then, the third drive mechanism 105 moves the plastic shell towards the plastic shell conveying track 400, so that the terminal piercing component 200 can process it. Then, the third drive mechanism 105 stops working, and the second drive mechanism 1041 drives the transfer disk 1042 to rotate, and the plastic shell falls back into the transfer channel. The above actions are repeated.

[0056] Generally, the material tray includes multiple supply channels arranged along the Y-axis. During operation, only one of the supply channels simultaneously connects the plastic shell through-hole and the first feed inlet. When all the plastic shells in this supply channel are used up, the feeding rack moving mechanism 101 drives the feeding rack 102 to move in the Y-axis direction. The adjacent supply channels are displaced and no longer blocked. The plastic shells in the adjacent supply channels enter the transfer channel again through the first feed inlet. This cycle is repeated to supply plastic shells in subsequent supply channels. The first driving mechanism 1011 drives the feeding rack to move along the Y-axis to achieve the function of automatic material changing.

[0057] It is understood that the number of rubber shells falling into the transfer channel each time can be one or more, depending on the specific processing requirements. However, the number of rubber shells falling into the transfer channel each time is less than the number in the supply channel. Therefore, the diameter of the transfer disk 1042 can be set to be smaller. During the rotation of the transfer disk 1042, the outer wall of the transfer disk 1042 abuts against the first discharge port to prevent the rubber shells from falling further.

[0058] In this scheme, firstly, the plastic shell feeding assembly 100 adopts a natural dropping method, allowing the plastic shell to fall into the transfer channel located on the transfer plate 1042. Then, the third drive mechanism 105 pushes the plastic shell onto the plastic shell conveying track 400, so that the terminal piercing assembly 200 can perform subsequent processing on it. This reduces the collision between plastic shells, and because the diameter of the transfer plate 1042 can be set to be smaller, the conveying distance is shortened, making the plastic shell discharge smoother.

[0059] Secondly, the arrangement of this solution makes better use of the space along the Z and Y axes, avoiding the arrangement of the feed box extending along the X axis as in the prior art, and can shorten the length of the production line while ensuring the amount of material supplied.

[0060] The number of rubber shells falling into the transfer channel each time can be controlled by setting the depth of the transfer channel or by controlling the rotation speed of the transfer disk 1042.

[0061] In some embodiments, a first air outlet nozzle 500 is provided above the material tray. The first air outlet nozzle 500 emits air vertically downwards, and the gas flows through the supply channel, passes through the first outlet, and then flows into the transfer channel. By setting the first air outlet nozzle 500 to emit air downwards, the gas acts on the rubber shell as it falls due to its own weight, making the rubber shell fall into the transfer channel more smoothly. At this time, the output power of the gas can be set to be relatively small.

[0062] In this embodiment, the arrangement of the first air outlet nozzle 500 above the material tray can be varied. One method is to set a first air outlet nozzle support 501 on the first track 1012. The first air outlet nozzle support 501 includes a vertical arm 502 extending along the Z-axis, a nozzle support arm 503 extending along the X-axis, and a connecting seat 504. The nozzle support arm 503 is connected to the vertical arm 502 through the connecting seat 504. The first air outlet nozzle 500 is located on the nozzle support arm 503, so the first air outlet nozzle 500 can be located above the material tray. By adjusting the locking screw on the connecting seat 504, the first air outlet nozzle 500 can slide along the X-axis and along the Z-axis, so that the first air outlet nozzle 500 can be adapted to material trays 103 of different lengths, which is convenient for adjustment.

[0063] In some embodiments, the third drive mechanism 105 includes a second exhaust nozzle 1051 and a first intake pipe 1052. The second exhaust nozzle 1051 is rotatably connected to the side wall of the transfer disk 1042 along the Y-axis. The exhaust end of the second exhaust nozzle 1051 extends into the transfer channel, and the intake end of the second exhaust nozzle 1051 is located outside the transfer channel and connected to a gas source through the first intake pipe 1052. Since the weight of a single housing is extremely light, using gas as the drive source for the third drive mechanism 105 has economic advantages. In this embodiment, the second exhaust nozzle 1051 is a rotary nozzle that can rotate relative to the transfer disk 1042. When the transfer disk 1042 rotates, the first intake pipe 1052 does not rotate with it, thus preventing the first intake pipe 1052 from loosening during long-term continuous rotation.

[0064] In some embodiments, the third driving mechanism 105 includes a slider 1053 and a sliding seat 1054 extending along the X-axis. The sliding seat 1054 is connected to the feeding rack moving mechanism 101. The sliding seat 1054 is provided with a slide rail 1055. The slider 1053 is slidably connected to the slide rail 1055. A push rod 1056 extending toward the transfer disk 1042 is connected to the slider 1053. The bottom of the transfer channel is provided with a through hole adapted to the push rod. Both ends of the sliding seat 1054 on the X-axis are provided with third air nozzles 1057. The air outlet end of the third air nozzle 1057 faces the slider 1053. When the transfer disk 1042 rotates, the push rod 1056 can move into the transfer channel.

[0065] In this embodiment, by using a gas-driven slider 1053 to reciprocate along the X-axis, the push rod 1056 on the slider 1053 can extend into the transfer channel to drive the rubber shell in the transfer channel to be pushed onto the rubber shell conveying track 400, which makes the movement of the rubber shell more stable.

[0066] There are several ways to move the push rod 1056 into the transfer channel. One way is that the bottom of the transfer channel has a through hole at the position of the outer wall in the X-axis direction that is adapted to the push rod 1056. When the transfer disk 1042 is not rotating, the push rod 1056 can be a certain distance away from the outer wall in the X-axis direction of the transfer disk 1042. When the transfer disk 1042 rotates, the position of the through hole changes accordingly, so that the push rod 1056 can move towards the transfer disk 1042 and be inserted into the transfer channel to push out the rubber shell.

[0067] The third air nozzles 1057 located at both ends of the X-axis of the sliding seat 1054 do not emit air simultaneously. When the slider 1053 needs to move towards the transfer disk 1042, the third air nozzle 1057 farther from the transfer disk 1042 emits air alone, causing the slider to move closer to the transfer disk 1042. When the slider 1053 needs to move away from the transfer disk 1042, the third air nozzle 1057 closer to the transfer disk 1042 emits air alone, driving the slider 1053 away from the transfer disk 1042, thereby achieving the reciprocating motion of the slider 1053. Using gas to drive the slider 1053 increases its moving speed and has high economic benefits.

[0068] In some embodiments, the sliding seat 1054 has wall plates at both ends of its X-axis, the slide rail 1055 is connected to the wall plates, and the third air nozzle 1057 is disposed on the wall plates. This arrangement allows the wall plates to limit the movement of the slider 1053, and simplifies the placement of the third air nozzle 1057, resulting in a simple structure and stable operation of the third drive mechanism 105.

[0069] In some embodiments, a fourth drive mechanism 600 and a transport gripper 601 are provided on the machine base 300 between the terminal piercing assembly 200 and the housing feeding assembly. The fourth drive mechanism 600 drives the transport gripper 601 to move along the X and Y directions. The lowest point of the transport gripper 601 is located on the Z-axis between the housing conveying track 400 and the top of the housing.

[0070] In this embodiment, the fourth drive mechanism 600 drives the transport gripper 601 to move along the X-axis and Y-axis. Initially, the transport gripper 601 is positioned on the X-axis near the plastic shell feeding assembly 100, and can block newly entering plastic shells into the plastic shell conveying track 400. When the transport gripper 601 moves away from the plastic shell conveying track 400 on the Y-axis, the plastic shell can be sent to the entrance end of the plastic shell conveying track 400 into the area corresponding to the fourth drive mechanism 600. In the plastic shell conveying track 400, the transport gripper 601 resets to one side of the plastic shell conveying track 400 on the Y-axis. Then, the fourth drive mechanism 600 drives the transport gripper 601 to move in the X-axis direction, moving the plastic shell towards the terminal piercing assembly 200 to realize the subsequent terminal piercing processing. Then, the transport gripper 601 resets in the X-axis direction, and the above actions are repeated. This can control the number of plastic shells entering the plastic shell conveying track 400 and keep the number of plastic shells entering the terminal piercing assembly 200 consistent.

[0071] In one embodiment, the fourth drive mechanism 600 includes a second track 602 extending along the X-axis, a slide block 603, a slide block drive source, a third track 604 extending along the Y-axis, a slide plate 605, and a slide plate drive source. The second track 602 extends from one end of the housing conveying track 400 near the transfer disk 1042 toward the terminal piercing assembly 200. The third track 604 is disposed on the slide block 603. The slide plate 605 is slidably connected to the third track 604. The slide block 603 is slidably connected to the second track 602. The second track 602 is disposed on the side of the terminal piercing assembly 200 away from the housing conveying track 400.

[0072] The transport gripper 601 includes a gripper connecting plate 6011 extending along the Z-axis and a gripper 6012 extending along the Y-axis. The sidewall of the gripper connecting plate 6011 is connected to the side of the slide plate 605 near the housing conveying track 400. The gripper 6012 is connected to the gripper connecting plate 6011. The gripper 6012 has two extension arms, which are arranged parallel to each other on the X-axis. The extension arms are located between the surface of the housing conveying track 400 and the top of the housing in the Z-axis direction. The power output end of the slide drive source is connected to the slide 603, causing the slide 603 to slide back and forth relative to the second track 602 along the X-axis. The power output end of the slide drive source is connected to the slide plate 605, driving the slide plate 605 to slide back and forth relative to the third track 604 along the Y-axis.

[0073] When a new plastic shell is ready to be transported from the transfer channel to the plastic shell transport track 400, the slide drive source drives the transport gripper 601 to move towards the slide 603, so that the extension arm does not block the plastic shell transport track 400. At this time, the plastic shell can be transported into the plastic shell transport track 400 between the two extension arms. Then, the slide drive source drives the slide plate 605 to move towards the plastic shell transport track 400, so that the extension arm blocks the plastic shell transport track 400 again. Subsequently, the slide drive source drives the slide 603 to slide towards the terminal piercing assembly 200, thereby realizing the transfer of the plastic shell.

[0074] In some embodiments, the side of the transport gripper 601 near the housing feeding assembly 100 has a gap with the inlet end of the housing conveying track 400. This arrangement of the transport gripper 601 facilitates the alignment of the housing before it enters the housing conveying track 400, preventing the housing from getting stuck at the inlet end of the housing conveying track 400.

[0075] In some embodiments, a foolproof cutting assembly 700 connected to the machine base 300 is provided between the housing feeding assembly 100 and the terminal piercing assembly 200. The foolproof cutting assembly includes a fifth drive mechanism 701 and a cutter 702. The cutter 702 is located above the housing conveying track 400, and the fifth drive mechanism 701 drives the cutter 702 to reciprocate up and down. During the process of the conveying gripper 601 moving the housing to the terminal piercing assembly 200, the cutter 702 can cut the housing during transport. By providing the foolproof cutting assembly 700, foolproof cutting of the housing in the housing conveying track 400 below the cutter 702 can be achieved without pre-cutting the housing, improving production versatility.

[0076] In some embodiments, a recycling pipe 703 is provided on one side of the plastic shell conveying track 400 corresponding to the foolproof structure cutting assembly 700. One end of the recycling pipe 703 opens toward the plastic shell conveying track 400, and the other end of the recycling pipe 703 is connected to a recycling device.

[0077] By configuring the recycling pipe 703 with one end opening towards the rubber shell conveying track 400, when the cutter 702 cuts the rubber shell, the generated waste enters the recycling device through the recycling pipe 703, avoiding interference with subsequent processing. The recycling device can be of various types, one of which is a negative pressure device. By setting a negative pressure device, the cut debris is attracted into the recycling pipe 703, resulting in a simple structure and good cleaning effect.

[0078] In some embodiments, the terminal piercing assembly 200 is provided with a detection assembly 800 on the side away from the housing feeding assembly 100. The detection assembly 800 includes an image acquisition device 801 arranged along the Z-axis. The image acquisition device 801 is electrically connected to an industrial control computer and is located above the housing conveying track 400.

[0079] By setting the detection component 800, the workpiece processed by the terminal puncture component 200 can be detected to check the cutting quality of the foolproof structure of the shell.

[0080] Specifically, the transport gripper 601 drives the workpiece, after being processed by the terminal piercing assembly 200, to continue moving along the plastic shell conveying track 400. When the workpiece moves to below the detection assembly 800, the image acquisition device 801 takes a picture of the workpiece and transmits the image back to the industrial control computer. The comparison software on the industrial control computer compares the captured image with a preset image to quickly determine whether the opening size of the plastic shell and the cut edge meet the requirements. If they meet the requirements, the transport gripper 601 continues to move; if they do not meet the requirements, the non-compliant plastic shell is pushed out by an external removal mechanism. The fourth drive mechanism 600 and the transport gripper 601 can drive the plastic shell to move from the inlet end of the plastic shell conveying track 400 to below the detection assembly 800.

[0081] Furthermore, another set of the fourth drive mechanism 600 and the transport gripper 601 are also provided between the detection component 800 and the terminal puncture component 200 to improve the efficiency of the casing conveying and increase the production speed.

[0082] Furthermore, the second tracks 602 in the two sets of the fourth drive mechanisms 600 are connected to better realize the alternating transport of materials.

[0083] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
