Description

Technical Field

[0001] This invention relates to the field of terminal block assembly technology, specifically to an adaptive fully automatic terminal equipment and its processing technology. Background Technology

[0002] Terminal blocks include multiple connectors mounted side-by-side on a frame, and terminals mounted on the connectors. The assembly of connectors and terminals is a process in the production of terminal products.

[0003] A connector terminal assembly machine, disclosed in the prior art (CN203205689U), includes a frame, a feeding device for conveying terminal strips, a clamping device for holding connector housings, a cutting device for cutting the terminal strips, and an insertion device for pushing the terminal strips into the housings. The feeding device, clamping device, cutting device, and insertion device are all mounted on the frame. The clamping device and the insertion device are arranged facing each other in a vertical plane. The feeding device is located on one side of the clamping device and the insertion device in the left-right direction, and on the same side of the frame in the front-back direction as the insertion device. The cutting device is located between the insertion device and the feeding device. The insertion device includes an insertion cylinder, an insertion slider, and an assembly head. The assembly head is located on the front end face of the insertion slider. The insertion slider is connected to the insertion cylinder. The insertion cylinder drives the insertion slider to slide back and forth, thereby pushing the assembly head to move back and forth. The terminal strip is then inserted into the connector housing in the clamping device under the push of the assembly head.

[0004] During operation: The assembly head is connected to the insertion cylinder via the insertion slider. When the terminal strip and the housing are in place, that is, when the housing reaches the position opposite to the assembly head, the terminal strip is transported between the assembly head and the housing. The insertion cylinder pushes the insertion slider forward, and the assembly head located at the front end of the insertion slider moves forward, thereby inserting the terminal strip into the housing and completing the assembly.

[0005] However, existing terminal blocks are manufactured using an assembly process. After the connectors are arranged sequentially, they are secured by fixing blocks and bolts at both ends of the terminal block. In reality, due to differences in the assembly of each connector and variations in bolt tightening, the actual distance between adjacent connectors deviates from the ideal distance. This deviation is positive or negative relative to the theoretical distance between the connectors, and its magnitude is variable. For example, the ideal distance between two adjacent connectors, and the fixed-distance movement distance of the terminals, is 10mm, while the actual distance between the two connectors may be... The deviations of 10.1mm or 9.9mm between multiple connectors accumulate sequentially, eventually causing the terminal block's structure to be unable to compensate for these accumulated deviations. During the subsequent assembly of the terminal block and terminals, the terminals are clamped and set to be assembled onto the connectors at an ideal spacing. Under the influence of the accumulated deviations, misalignment occurs between the sequentially aligned terminals and connectors, causing the terminals to fail to align with the connectors, resulting in low assembly accuracy or failure to achieve the assembly objective. Therefore, an assembly mechanism that can adjust the deviation between the connectors and terminals in real time is needed. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an adaptive fully automatic terminal equipment and its processing technology.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an adaptive fully automatic terminal device, comprising:

[0008] Terminal block, comprising multiple frame bodies and connector units stacked sequentially on the frame bodies;

[0009] A first mobile module has a fixed plate on its actuating end, a compensation component on the fixed plate, a terminal block connected to the compensation component, and the first mobile module drives the terminal block to the assembly position.

[0010] The compensation assembly includes a floating seat that is floatingly disposed on a fixed plate with respect to the arrangement direction of the plug-in units, and a compensation unit disposed on the floating seat. The fixed plate is provided with a floating space, the compensation unit is placed in the floating space, and a floating gap is formed on at least one side of the floating space.

[0011] The second moving module is provided with a correction unit and a clamping module. The first moving module drives the correction unit and the clamping module to move at a fixed distance about the assembly position. The correction unit is provided with a guide port and a correction port. The guide port guides the connector unit into the correction port. The correction port constrains the connector unit at a fixed distance. The clamping module carries a terminal. The terminal is assembled with the connector unit at a fixed distance.

[0012] Furthermore, the theoretical distance between the second moving module driving the correction unit and the clamping module to move at a fixed distance about the direction of the plug-in unit arrangement is L1; the actual distance between the centers of the two plug-in units is L2; ​​the difference between the actual distance L2 and the theoretical distance L1 is the deviation distance Ln, the sum of multiple deviation distances Ln is the cumulative deviation Lx, and the floating gap Ly is greater than the cumulative deviation Lx.

[0013] Furthermore, the compensation unit has a floating position and a reference position. In the floating position, the compensation unit extends into the floating space, and the compensation component is allowed to move left and right in the floating space. In the reference position, the compensation unit continues to extend and limits the compensation component to the current position.

[0014] Furthermore, the end of the compensation unit is provided with a friction block, which abuts against the moving module or against the fixed plate to restrict the movement of the compensation component.

[0015] Furthermore, the floating seat is also provided with a return unit, and the fixed plate is provided with a return hole opposite to the return unit. The end of the return unit is provided with a guide surface, and the guide surface abuts against the return hole and pulls the floating seat so that the compensation unit moves to the center of the floating space.

[0016] Furthermore, the terminal block has at least two mounting surfaces arranged front to back, and the connector units are arranged on the mounting surfaces;

[0017] The floating base is equipped with a flipping mechanism, which is used to drive any assembly surface of the terminal block to face the calibration unit and the clamping module.

[0018] Furthermore, the bottom of the floating seat is provided with a mounting plate, the mounting plate is provided with a fixing component for fixing the terminal block, and the floating seat is also provided with a limiting unit for limiting the mounting plate to its current position.

[0019] Furthermore, the fixing assembly includes a lead screw arranged on the mounting plate, a fixing block defined at one end of the lead screw, and a sliding block movably disposed on the lead screw, wherein the fixing block and the sliding block are defined at both ends of the terminal block.

[0020] Furthermore, the clamping module also has a feeding position, at which a first adjustment component is provided opposite to the clamping module. The first adjustment component has a clamping arm for clamping the terminal and a first rotation module for driving the clamping arm to rotate. The first rotation module drives the terminal to rotate to be coplanar with the connector unit.

[0021] Furthermore, the clamping module is also provided with a second adjustment component, which includes at least a second rotation module that is pulsatorically connected to the clamping module. The second rotation module drives the terminal to rotate so that it is directly opposite the connector unit.

[0022] The present invention also provides a processing technology for an adaptive fully automatic terminal equipment, comprising the following steps:

[0023] S1 Pre-alignment: The first moving module drives the floating seat to move to the fixed plate. At this time, the compensation unit is located in the floating space. The alignment unit moves and pulls the floating seat so that the compensation unit is located in the middle of the floating space.

[0024] S2 Terminal alignment: The terminal is transported to the loading position, and the assembly position of the connector unit is aligned with the positive direction of the Y-axis. If the assembly port of the terminal is aligned with the assembly position of the connector unit, proceed to step S3.

[0025] If the terminal's mounting port is located in the X-axis direction, the first adjustment component clamps the terminal and rotates the first rotation module about the Y-axis so that the terminal's mounting port is coplanar with the connector unit. If the terminal's mounting port is directly opposite the connector unit's mounting position, the clamping module clamps the terminal and proceeds to step S3.

[0026] If the assembly port of the terminal is located in the Z-axis direction, the clamping module will move and clamp the terminal. At this time, the clamping arm of the first adjustment component will release the clamp, and the second adjustment component will move and drive the clamping module to rotate about the X-axis so that the assembly port of the terminal is aligned with the insertion unit, and then proceed to step S3.

[0027] S3 First calibration: The first moving module drives the floating seat to the assembly position, and the second moving module drives the calibration unit and clamping module to the assembly position. The calibration unit moves and pulls the first plug-in unit to the ideal position. At this time, the floating seat and the compensation unit move a distance in the floating space and compensate for the cumulative deviation of multiple plug-in units. The second moving module moves further and drives the clamping module to directly connect the plug-in unit, completing the docking of the terminal and the plug-in unit.

[0028] S4 Secondary Correction: The compensation unit moves to the reference position and restricts the movement of the floating seat. Taking the first plug-in unit as the reference, the second moving module drives the correction unit to move at a fixed distance. The correction unit moves and pulls the next plug-in unit to the ideal position. The second moving module moves further and drives the clamping module to directly connect the plug-in unit, completing the docking of the terminal and the plug-in unit. Repeat actions S2 and S4 until the plug-in units in the same row on the current assembly surface are assembled.

[0029] S5 Secondary Return: After completing the assembly of the current column of plug-in units on the current assembly surface, proceed to step S1. At this time, the second moving module moves one distance to assemble the next column of plug-in units, and proceeds to steps S3 and S4 until the assembly of plug-in units on the current assembly surface is completed.

[0030] S6 Assembly Surface Switching: After completing the assembly of the plug-in unit on the current assembly surface, the component flipping action is performed and the terminal block is driven to rotate about the Z-axis so that the next assembly surface faces the assembly position, and steps S1 to S5 are repeated.

[0031] Compared with the prior art, the present invention has the following advantages and beneficial effects: In the initial state, the compensation unit is placed in the middle of the floating space, so that the floating seat can drive the terminal block to move left and right by a certain distance in the arrangement direction of the plug-in units, thereby compensating for the cumulative deviation between the plug-in units. In the working state, the terminal block is transported to the assembly position by the first moving module. At this time, the correction unit moves to the first plug-in unit and constrains the plug-in unit in the current position by the guide port and correction port on the correction unit. Under the abutment of the guide port, the terminal block is forced to drive the floating seat to move in the floating space to achieve the compensation of the cumulative deviation. At the same time, the compensation unit extends to the reference position and limits the position of the floating seat, so that the plug-in unit is used as the reference and the assembly between the plug-in unit and the terminal is completed by the clamping module. Then, the correction unit moves sequentially at a fixed distance and corrects the plug-in units in turn, so that each plug-in unit is constrained to the ideal distance, and the precise assembly between the plug-in unit and the terminal is achieved.

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0057] like Figure 1-11 As shown, a floating terminal mechanism includes:

[0058] Terminal block 1 includes at least one frame body 1.1 and plug-in units 1.2 stacked sequentially on the frame body 1.1;

[0059] A first moving module 2 is provided with a fixed plate 3 on its moving end. A slidable compensation component 4 is provided on the fixed plate 3. A terminal block 1 is carried on the compensation component 4, and the first moving module 2 drives the terminal block 1 to the assembly position.

[0060] The compensation component 4 includes a floating seat 4.1 that is floatingly disposed on a fixed plate 3 with respect to the arrangement direction of the plug-in units 1.2, and a compensation unit 4.2 disposed on the floating seat 4.1. The fixed plate 3 is provided with a floating space 3.1, the compensation unit 4.2 is placed in the floating space 3.1, and a floating gap 3.11 is formed on at least one side of the floating space 3.1. The floating gap 3.11 is used to compensate for the cumulative deviation of multiple plug-in units 1.2.

[0061] The second moving module 5 has a correction unit 6 and a clamping module 7 on its actuating end. The first moving module 2 drives the correction unit 6 and the clamping module 7 to the assembly position and moves at a fixed distance from the assembly position. The correction unit 6 has a guide port 6.1 and a correction port 6.2. The guide port 6.1 guides the connector 1.2 into the correction port 6.2, and the correction port 6.2 constrains the connector 1.2 at a fixed distance, thereby offsetting the connector 1.2 to the ideal position. The clamping module 7 carries a terminal, which is assembled with the connector 1.2 at a fixed distance. The correction unit 6 and the clamping module 7 are both fixed on the actuating end of the second moving module 5, so that the correction unit 6 and the clamping module 7 can move at a fixed distance with an ideal gap. Thus, the correction unit 6 can pull the floating seat 4.1, which floats relative to the fixed plate 3, and the current connector 1.2 to the ideal position.

[0062] It should be noted that although there is a cumulative deviation between the multiple plug-in units 1.2, the cumulative deviation is less than the distance between the outermost boundary of the guide port 6.1 and the correction port 6.2, thus ensuring the correction effect of the correction unit 6 on the floating seat 4.1 and the plug-in unit 1.2.

[0063] like Figures 9 to 11 As shown, specifically, the theoretical distance between the second moving module 5 driving the correction unit 6 and the clamping module 7 to move at a fixed distance about the arrangement direction of the plugging unit 1.2 is L1;

[0064] The actual distance between the centers of the two connector units 1.2 is L2;

[0065] The difference between the actual spacing L2 and the theoretical spacing L1 is the deviation spacing Ln. The sum of multiple deviation spacings Ln is the cumulative deviation Lx. The floating gap 3.11Ly is greater than the cumulative deviation Lx.

[0066] like Figure 9 As shown, a flared opening is formed at the guide port 6.1 for inserting the connector unit 1.2. The flared opening allows the connector unit 1.2 to move within it, and the one-sided distance Lz between the guide port 6.1 and the correction port 6.2 is greater than the deviation distance Ln. Preferably, the one-sided distance Lz is also greater than the cumulative deviation Lx, and the contour of the correction port 6.2 matches that of the connector unit 1.2.

[0067] like Figure 2 and Figure 4As shown, as a further explanation of the floating seat 4.1 and the fixed plate 3, the fixed plate 3 is a plate body that is vertically arranged on the moving end of the first moving module 2. The floating seat 4.1 is an L-shaped seat body, which has a vertical plate arranged parallel to the fixed plate 3 and a horizontal plate arranged perpendicular to the fixed plate 3. A slide rail slider is provided between the fixed plate 3 and the floating seat 4.1 so that the floating seat 4.1 can slide relative to the fixed plate 3.

[0068] like Figure 10 and Figure 11 As shown, as a further improvement to the present invention, the compensation unit 4.2 has a floating position and a reference position. The compensation unit 4.2 extends into the floating space 3.1 in the floating position, and the compensation component 4 is allowed to move left and right in the floating space 3.1. The compensation unit 4.2 continues to extend in the reference position, and the compensation component 4 is limited to the current position.

[0069] Through the above improvements, the compensation unit 4.2 moves to the reference position after the correction unit 6 corrects the first plug-in unit 1.2. That is, the compensation unit 4.2 moves after completing the initial compensation. In the reference position, the floating seat 4.1 is restricted from moving relative to the fixed plate 3. The subsequent plug-in units 1.2 are all compensated with the first plug-in unit 1.2 as the reference and under the action of the fixed distance movement of the correction unit 6, so that each plug-in unit 1.2 can be in the ideal position, that is, the distance between two adjacent plug-in units 1.2 reaches the ideal distance, thereby ensuring that the clamping module 7 can carry the terminal and achieve precise assembly with the plug-in unit 1.2.

[0070] As a further embodiment of the floating space 3.1 and the compensation unit 4.2, the compensation unit 4.2 is connected to the actuating end of the first ejector cylinder 4.4, and both the compensation unit 4.2 and the floating space 3.1 have square cross-sections. Preferably, the floating space 3.1 and the compensation unit 4.2 have a pre-set floating gap 3.11 only in the arrangement direction of the insertion unit 1.2, and the other boundaries of the compensation unit 4.2 and the floating space 3.1 have only a pre-set sliding gap, so that the compensation unit 4.2 can move in the floating space 3.1 and play a certain guiding role.

[0071] It should be noted that, under the guidance of this invention, those skilled in the art may also choose other shapes, as long as a floating gap 3.11 that is greater than the cumulative deviation is formed between the boundary of the compensation unit 4.2 and the boundary of the floating space 3.1.

[0072] Specifically, the switching of the compensation unit 4.2 between the floating position and the reference position is achieved by the first ejection cylinder 4.4 set on the floating seat 4.1, that is, the reference position extends further relative to the floating position.

[0073] Specifically, the compensation unit 4.2 has a friction block 4.21 at its end. The friction block 4.21 abuts against the moving module or against the fixed plate 3 to restrict the movement of the compensation component 4. Preferably, the friction block 4.21 can be made of rubber.

[0074] Specifically, the terminal block 1 has at least two mounting surfaces arranged front and back, and the connector unit 1.2 is arranged on the mounting surfaces. In some embodiments, the terminal block 1 also has two mounting surfaces arranged vertically, that is, there are two mounting surfaces on the front and back of the terminal block 1. For this purpose, the floating seat 4.1 is provided with a flipping mechanism 8. The flipping mechanism 8 is used to drive any mounting surface of the terminal block 1 to face the correction unit 6 and the clamping module 7, and the second moving module 5 can drive the correction unit 6 and the clamping module 7 to move on the XYZ three axes, thereby satisfying the assembly of the terminal and the connector unit 1.2 on any mounting surface.

[0075] To address the issue of terminal block 1 having multiple mounting surfaces, after completing the assembly work on one mounting surface, the relative position of compensation unit 4.2 and floating space 3.1 needs to be corrected. That is, compensation unit 4.2 is returned to the middle of floating space 3.1, so that floating space 3.1 has floating gaps 3.11 on both sides of compensation unit 4.2 to accommodate cumulative deviations in different directions.

[0076] In this embodiment, the floating seat 4.1 is also provided with a return unit 4.3, and the fixed plate 3 is provided with a return hole 3.2 opposite to the return unit 4.3. The end of the return unit 4.3 is provided with a guide surface 4.31. The guide surface 4.31 abuts against the return hole 3.2 and pulls the floating seat 4.1 back to the initial position, so that the compensation unit 4.2 moves to the middle of the floating space 3.1.

[0077] The end of the return unit 4.3 can be a conical surface. After compensation, the floating seat 4.1 moves relative to the fixed plate 3. The conical surface on the return unit 4.3 has a certain deviation from the return hole 3.2, while the boundary of the return hole 3.2 is still aligned with the conical surface area. Thus, the return unit 4.3 extends and inserts into the return hole 3.2, pulling the floating seat 4.1 to the initial position to achieve return. This allows for the remaining assembly surface compensation, correction, and assembly.

[0078] Preferably, the unilateral distance Lz between the central axis of the aligning unit 4.3 and the boundary of the conical surface is greater than the cumulative deviation Ln, so as to ensure the above-mentioned aligning effect.

[0079] Specifically, the extension and retraction of the return unit 4.3 are achieved by the second ejector cylinder 4.5 mounted on the floating seat 4.1.

[0080] Preferably, the clamping module 7 and the correction unit 6 are vertically aligned and flush, and the ideal spacing of the plug-in units 1.2 corresponds to the fixed-distance movement spacing of the correction unit 6, so that each plug-in unit 1.2 is pulled to the ideal position by the fixed-distance movement of the correction unit 6.

[0081] like Figure 5 As shown, as a further embodiment of fixing the terminal block 1, the bottom of the floating seat 4.1 is provided with a mounting plate 9, which is parallel to the horizontal plate of the floating seat 4.1. The mounting plate 9 is provided with a fixing component 10 for fixing the terminal block 1. The flipping component for driving the assembly surface of the terminal block 1 to switch is provided on the horizontal plate of the floating seat 4.1. The floating seat 4.1 is also provided with a limiting unit 11 for limiting the mounting plate 9 in the current position.

[0082] Specifically, the fixing component 10 includes a lead screw 10.1 arranged on the mounting plate 9, a fixing block 10.2 defined at one end of the lead screw 10.1, and a sliding block 10.3 movably arranged on the lead screw 10.1. The fixing block 10.2 and the sliding block 10.3 are defined at both ends of the terminal block 1. The lead screw 10.1 can be driven to rotate by a rocker wheel or by a motor 8.1.

[0083] Specifically, the flipping assembly includes a motor 8.1 erected on a horizontal plate and a transmission wheel 8.2 that drives the output of the motor 8.1. The transmission wheel 8.2 and the output of the motor 8.1 can be driven by a belt or by a gear meshing. The transmission wheel 8.2 is fixedly connected to the mounting plate 9 through a fixed shaft, thereby enabling the mounting plate 9 to rotate and thus rotate the other mounting surface to the opposite surface of the correction unit 6 and the clamping module 7.

[0084] Specifically, the limiting unit 11 includes a first limiting post and a second limiting post arranged vertically on a horizontal plate. Both the first limiting post and the second limiting post are driven by a third ejection cylinder 11.1. The mounting plate 9 is provided with limiting holes that are opposite to the first limiting post and the second limiting post. By inserting the limiting post into the limiting hole, the rotation of the mounting plate 9 is restricted, ensuring that the mounting plate 9 is in the current position and improving the reliability of assembly and correction.

[0085] like Figure 6 and Figure 7As shown, as a further embodiment of the correction unit 6 and the clamping module 7, the second moving module 5 has an XYZ direction module to drive the correction unit 6 and the clamping module 7 to move along the XYZ direction, thereby realizing the correction of the connector unit 1.2 on each assembly surface and the assembly between the connector unit 1.2 and the terminal. The Y direction module of the second moving module 5 is provided with a mounting base plate 5.1, and the correction unit 6 and the clamping module 7 are both disposed on the mounting base plate 5.1. After the XZ direction module of the second moving module 5 drives the correction unit 6 and the clamping module 7 to move to the assembly position, the Y direction module is used to drive the mounting base plate 5.1 to move toward the terminal block 1 and perform pre-positioning.

[0086] Specifically, the calibration unit 6 is arranged on the upper surface of the mounting base plate 5.1, and the clamping module 7 is arranged on the lower surface of the mounting base, so that the calibration unit 6 or the clamping module 7 is aligned with the insertion unit 1.2 through the action of the Z-axis module.

[0087] The mounting base plate 5.1 is also equipped with a calibration cylinder 6.3. The calibration unit 6 is connected to the output end of the calibration cylinder 6.3. The calibration unit 6 extends toward the connector unit 1.2 by being driven by the calibration cylinder 6.3.

[0088] The mounting base plate 5.1 has a fourth ejector cylinder 7.2 at its bottom, and the clamping module 7 is set on the actuating end of the fourth ejector cylinder 7.2. The assembly between the terminal and the connector unit 1.2 is achieved through the fourth ejector cylinder 7.2.

[0089] In other embodiments, the clamping module 7 also has a feeding position, and the second moving module 5 drives the clamping module 7 to switch between the feeding position and the assembly position. Due to the limitation of the terminal conveying channel, there is a situation where the assembly port of the terminal and the assembly position of the connector 1.2 are not in the same direction. The feeding position is also provided with a first adjustment component 12 that is directly opposite to the clamping module 7, and the mounting base plate 5.1 is also provided with a second adjustment component 7.1. The second adjustment component 7.1 is connected to the clamping module 7 in a transmission manner, wherein the first adjustment component 12 and the second adjustment component 7.1 drive the terminal to rotate.

[0090] The assembly position of the connector unit 1.2 is located in the YZ plane and points in the positive Y direction.

[0091] As one embodiment of the first adjustment component 12, the first adjustment component 12 and the clamping module 7 are arranged opposite each other in the Y direction on both sides of the terminal conveying channel, that is, the loading position is arranged on the terminal conveying channel. The first adjustment component 12 includes a fixing frame 12.3, a first rotating module 12.2 arranged on the fixing frame 12.3, and a clamping arm 12.1 arranged on the first rotating module 12.2. The first rotating module 12.2 refers to a turntable that can rotate around the Y axis. The clamping arm 12.1 is driven by pneumatic fingers arranged on the turntable to close or open with each other. The clamping arm 12.1 clamps terminals in different postures through the first rotating module 12.2 and carries the terminals to rotate so that the assembly port of the terminal and the connector unit 1.2 are located in the same plane.

[0092] like Figure 8 As shown, in one embodiment of the second adjustment component 7.1, the second adjustment component 7.1 includes a second rotating module 7.11 that is pulsatorically connected to the clamping module 7, and a fifth ejection cylinder 7.12 and a guide rail 7.13 arranged at the bottom of the mounting base plate 5.1. The second rotating module 7.11 includes a rack 7.111 slidably disposed in the guide rail 7.13. The rack 7.111 is connected to the actuating end of the fifth ejection cylinder 7.12, and a gear 7.112 meshes with the lower part of the rack 7.111. The gear 7.112 is axially connected to a rotating shaft, which is arranged about the X-axis and fixedly connected to the clamping module 7. Thus, the action of the fifth ejection cylinder 7.12 drives the clamping module 7 to rotate around the X-axis, thereby realizing the adjustment and alignment of the terminal assembly port and the assembly position of the connector unit 1.2.

[0093] Through the above improvements, both the first adjustment component 12 and the second adjustment component 7.1 can clamp the terminal. The rotation surfaces of the first adjustment component 12 and the second adjustment component 7.1 are perpendicular to each other. Depending on the opening direction of the terminal's assembly port in the conveying position, the first adjustment component 12 and the second adjustment component 7.1 can be selected, or the first adjustment component 12 and the second adjustment component 7.1 can be combined, so that the terminal's assembly port is directly aligned with the mating unit 1.2, ensuring normal assembly of the terminal and the mating unit 1.2.

[0094] It should be noted that in the terminal transportation design, the terminal is set to be transported with the assembly port in the horizontal or vertical positive direction, so that the first adjustment component 12 and the second adjustment component 7.1 can be used to ensure that the assembly port of the terminal is aligned with the assembly position of the connector unit 1.2.

[0095] As one embodiment of terminal transportation, a terminal transportation mechanism is provided on the side of the first adjustment component 12 away from the compensation component 4. The terminal transportation mechanism contains a terminal strip and a cutting mechanism with a vertically arranged cutting blade to separate individual terminals from the strip. Alternatively, the terminals may be pre-cut and transported individually in the transportation channel. A third moving module is also provided in the X direction, which is equipped with a transfer module for clamping individual terminals and transferring them to the first adjustment component 12 for terminal assembly alignment.

[0096] Specifically, the transfer module operates at the rear end of the terminal or on the terminal's wiring harness, thereby making way for the first adjustment component 12 or the clamping module 7.

[0097] In the initial state, the compensation unit 4.2 is placed in the middle of the floating space 3.1, allowing the floating seat 4.1 to move the terminal block 1 a certain distance to the left or right in the arrangement direction of the connector units 1.2, thereby compensating for the cumulative deviation between the connector units 1.2. In the working state, the terminal block 1 is transported to the assembly position by the first moving module 2. At this time, the correction unit 6 moves to the first connector unit 1.2 and constrains the connector unit 1.2 to its current position through the guide port 6.1 and the correction port 6.2 on the correction unit 6. Under the action of contact, the terminal block 1 is forced to move the floating seat 4.1 within the floating space 3.1 to compensate for the cumulative deviation. At the same time, the compensation unit 4.2 extends to the reference position to limit the position of the floating seat 4.1, so that the connector 1.2 is used as the reference and the clamping module 7 completes the assembly between the connector 1.2 and the terminal. Then, the fixed-distance correction unit 6 moves sequentially and corrects the connector 1.2 in turn, so that each connector 1.2 is constrained to the ideal distance, and the precise assembly of the connector 1.2 and the terminal is achieved.

[0098] The present invention also provides a processing technology for an adaptive fully automatic terminal equipment, comprising the following steps:

[0099] S1 Pre-alignment: The first moving module 2 drives the floating seat 4.1 to move to the fixed plate 3. At this time, the compensation unit 4.2 is located in the floating space 3.1. The alignment unit 4.3 is activated and pulls the floating seat 4.1 so that the compensation unit 4.2 is located in the middle of the floating space 3.1.

[0100] S2 Terminal alignment: The terminal is transported to the loading position, and the assembly position of the connector unit 1.2 is aligned with the positive Y-axis direction. If the assembly port of the terminal is aligned with the assembly position of the connector unit 1.2, then proceed to step S3.

[0101] If the terminal's mounting port is located in the X-axis direction, the first adjustment component 12 clamps the terminal and rotates the first rotation module 12.2 about the Y-axis so that the terminal's mounting port is coplanar with the connector unit 1.2. If the terminal's mounting port is directly opposite the mounting position of the connector unit 1.2, the clamping module 7 clamps the terminal and proceeds to step S3.

[0102] If the assembly port of the terminal is located in the Z-axis direction, the clamping module 7 will move and clamp the terminal. At this time, the clamping arm 12.1 of the first adjustment component 12 will release the clamp, and the second adjustment component 7.1 will move and drive the clamping module 7 to rotate about the X-axis so that the assembly port of the terminal is aligned with the insertion unit 1.2, and then proceed to step S3.

[0103] S3 First calibration: The first moving module 2 drives the floating seat 4.1 to the assembly position, and the second moving module 5 drives the calibration unit 6 and the clamping module 7 to the assembly position. The calibration unit 6 moves and pulls the first plug-in unit 1.2 to the ideal position. At this time, the floating seat 4.1 and the compensation unit 4.2 move a distance within the floating space 3.1 and compensate for the cumulative deviation of multiple plug-in units 1.2. The second moving module 5 moves further and drives the clamping module 7 to directly connect with the plug-in unit 1.2, completing the docking of the terminal with the plug-in unit 1.2.

[0104] S4 Secondary Correction: The compensation unit 4.2 moves to the reference position and restricts the movement of the floating seat 4.1. Taking the first plug-in unit 1.2 as the reference, the second moving module 5 drives the correction unit 6 to move at a fixed distance, and the correction unit 6 moves and pulls the next plug-in unit 1.2 to the ideal position. The second moving module 5 moves further and drives the clamping module 7 to directly connect to the plug-in unit 1.2, completing the docking of the terminal and the plug-in unit 1.2. Repeat actions S2 and S4 until the plug-in units 1.2 in the same row on the current assembly surface are assembled.

[0105] S5 Secondary Correction: After completing the assembly of the current column connector unit 1.2 within the current assembly surface, proceed to step S1. At this time, the second moving module 5 moves by one distance to assemble the next column connector unit 1.2, and proceeds to steps S3 and S4 until the assembly of connector unit 1.2 on the current assembly surface is completed.

[0106] S6 Assembly Surface Switching: After completing the assembly of the connector unit 1.2 on the current assembly surface, the component flipping action is performed and the terminal block 1 is driven to rotate about the Z-axis so that the next assembly surface faces the assembly position, and steps S1 to S5 are repeated.

[0107] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
