Description

Technical Field

[0001] This application relates to the technical field of terminal block assembly, and in particular to a fully automatic terminal block plugging and assembling machine. Background Art

[0002] A terminal block is an insulating component that carries multiple or multiple groups of mutually insulated terminal components and is used to fix the support. Its main function is to connect the lines of the in-panel equipment and the out-panel equipment to achieve the transmission of signals (current and voltage). The existence of the terminal block not only makes the wiring more beautiful, but also provides convenience for the maintenance and replacement of equipment. Especially when connecting long-distance lines, the terminal block ensures the reliability of the connection and simplifies the construction and maintenance processes.

[0003] In the related art, the structure of the terminal block mainly includes a terminal base, a plurality of wiring terminals (voltage terminals and current terminals) installed on the terminal base, and a shunt used specifically for connecting adjacent multiple wiring terminals. The shunt usually consists of a metal conductive sheet and a screw that cooperates with it, and can electrically connect multiple wiring terminals into a whole.

[0004] During the assembly process, the wiring terminals are pre-installed on the terminal base, and then the shunt is placed in the groove on the side of adjacent multiple wiring terminals to ensure that the metal conductive sheet is in close contact with the wiring terminals. Subsequently, screws are used to fix the metal conductive sheet to the corresponding multiple wiring terminals, and finally, insulating spacers are inserted between adjacent wiring assemblies; these insulating spacers can effectively separate different wiring assemblies and prevent short circuits between different circuits.

[0005] However, although the assembly design of the terminal block is quite perfect, there are still some deficiencies during the assembly process. Currently, the terminal block is usually assembled manually, and the steps of this process are rather cumbersome, not only consuming a large amount of time, but also requiring more labor costs, and there is room for improvement. Summary of the Invention

[0006] The purpose of this application is to provide a fully automatic terminal block plugging and assembling machine to solve the problems of high assembly cost and low assembly efficiency of the terminal block in the above related art.

[0007] A fully automatic terminal block plugging and assembling machine provided by this application adopts the following technical solutions:

[0008] A fully automatic plug-in assembly machine for terminal blocks, including a processing table, on which a voltage terminal assembly area, a current terminal assembly area, and a terminal block feeding assembly penetrating through the two assembly areas are provided; both the voltage terminal assembly area and the current terminal assembly area are provided with a first feeding assembly for terminal feeding, a first clamping assembly for terminal clamping, a clamping assembly for assembling terminals and end caps, a second clamping assembly for clamping parallel components, and a third clamping assembly for feeding and clamping insulating spacers.

[0009] By adopting the above technical solution, during the process of installing the terminals onto the terminal block, first, the terminals are fed through the first feeding assembly, then the terminals are installed at the corresponding positions of the terminal block by the first clamping assembly, then the parallel components are clamped and fixed by the second clamping assembly, and finally the insulating spacers are installed by the third clamping assembly, and the insulating spacers are inserted into the voltage terminal gaps between adjacent parallel components; thus, the automatic assembly of the terminal block is realized, thereby improving the assembly efficiency of the terminal block and reducing the assembly cost of the terminal block.

[0010] Optionally, the first feeding assembly includes two horizontally arranged support rods and a support frame located on the side of the processing table. The two support rods are distributed up and down and rotatably arranged on the support frame. Transmission gears are fixedly sleeved at both ends of the support rods; a driving member for driving the support rods to rotate and a transmission chain sleeved on the outer circumferences of the upper and lower transmission gears are provided on the side of the support frame; several receiving plates with the center of gravity downward are provided on the side of the support frame. Both ends of the receiving plate are rotatably connected to the mutually approaching sides of the two transmission chains, and a receiving groove for placing the terminals is opened on the receiving plate.

[0011] By adopting the above technical solution, due to the layout of the support rods and the receiving plates, when the terminals on the uppermost receiving plate are taken, the driving member drives the transmission chain to act, causing the lower receiving plate to rotate upward; thus, the three-dimensional space is reasonably utilized, thereby reducing the overall occupied space of the first feeding assembly and reducing the costs of transportation, installation, and future maintenance and management.

[0012] Optionally, a tray for accommodating the terminals and located in the receiving groove is provided on the receiving plate. Both ends of the tray are respectively a feeding end and a discharging end; a limiting plate is fixedly provided on the upper side of the tray near the discharging end, and a discharging gap is preset between the limiting plate and the discharging end; a pushing member is provided on the support frame, and the pushing member is used to push the terminals in the tray from the feeding end towards the direction close to the discharging end.

[0013] By adopting the above technical solution, due to the installation of the tray, the staff can pre-place the terminals to be assembled inside the tray, and then place the whole tray inside the receiving groove on the receiving plate, so as to improve the efficiency of placing the terminals into the receiving groove, and further improve the overall subsequent assembly efficiency of the terminal block; and due to the setting of the pushing member and the limiting plate, the mechanical claw grabs the terminals located in the discharging gap, and at the same time, the limiting plate prevents the terminals located in the discharging gap from bringing out adjacent terminals due to friction. When the mechanical claw grabs the terminals in the tray, the pushing member is used to push the remaining terminals in the tray towards the discharging end, so as to prevent the remaining terminals from being scattered.

[0014] Optionally, an extrusion cylinder is arranged in the support frame below the uppermost receiving plate, and an extrusion plate is arranged on the telescopic rod of the extrusion cylinder; a positioning plate for supporting and fixing the extrusion cylinder is fixedly arranged in the support frame, and the extrusion plate can abut against the bottom side of the uppermost receiving plate.

[0015] By adopting the above technical solution, due to the setting of the positioning plate, the extrusion cylinder and the extrusion plate, when the lower receiving plate moves to the uppermost position, the extrusion cylinder on the positioning plate is started to tightly abut against the bottom side of the uppermost receiving plate, reducing the possibility of the receiving plate loosening when the mechanical claw grabs the terminals subsequently, and improving the installation stability of the receiving plate when the mechanical claw grabs the terminals.

[0016] Optionally, the first clamping assembly includes a clamping member located above the processing table and a driving source for driving the clamping member to move along the horizontal plane and the vertical plane; a support arm for supporting the driving source is arranged on the processing table; the clamping member includes a mounting plate arranged on the driving source, a fixing plate arranged on the side of the mounting plate, and a pneumatic claw rotatably arranged on the vertical side of the fixing plate. An adjusting assembly for adjusting the rotation angle of the pneumatic claw is arranged on the side of the fixing plate, and the pneumatic claw can be rotated and adjusted along the vertical plane and fixed.

[0017] By adopting the above technical solution, when the pneumatic claw fixes the clamped terminal on the terminal block, the driving source drives the pneumatic claw to reciprocate towards the terminal block. Due to the installation of the pneumatic claw and the adjusting assembly, the installation angle of the pneumatic claw relative to the upper surface of the terminal block can be adjusted; that is, first hook one side of the terminal into one of the card slots, and then rotate the other hook into the other card slot. The step-by-step card-in design reduces the damage to the terminal and the terminal block during the installation process, thereby extending their service life.

[0018] Optionally, the adjusting assembly includes a support plate slidably disposed on the vertical side of the fixing plate and an adjusting cylinder fixedly disposed on the vertical side of the fixing plate in the vertical direction. The end of the telescopic rod of the adjusting cylinder is hinged to the side of the support plate away from the processing table. A guide rod is fixedly disposed on the side of the support plate. A waist-shaped guide hole is formed in the fixing plate for the guide rod to penetrate and slide, and the length direction of the waist-shaped guide hole is parallel to the upper side of the processing table. The adjusting cylinder can drive the guide rod to slide along the length direction of the waist-shaped guide hole and the guide rod rotates around its own axis.

[0019] By adopting the above technical solution, when the pneumatic gripper needs to adjust the angle, the adjusting cylinder is started to drive the guide rod on the support plate to slide along the length direction of the waist-shaped guide hole and the guide rod rotates around its own axis, thereby driving the pneumatic gripper on the support plate to rotate, so as to realize the adjustment of the installation angle of the pneumatic gripper, which is convenient for the subsequent step-by-step assembly and fixation of the terminal and the terminal block.

[0020] Optionally, the fixing plate is slidably disposed on the vertical side of the mounting plate. First guide posts are arranged on the side of the fixing plate in the height direction. First guide through grooves are formed in the mounting plate for the first guide posts to penetrate and slide. A first compression spring in a compressed state is sleeved on the outer periphery of the first guide post, and the first compression spring is located on the side of the receiving plate facing the processing table.

[0021] By adopting the above technical solution, due to the cooperative setting of the first guide post and the first compression spring, when the fixing plate drives the terminal clamped by the pneumatic gripper to move in the direction close to the terminal block, due to the installation of the first compression spring, it plays a buffering role during the vertical movement, reducing the possibility of deformation or damage of the terminal or the terminal block caused by excessive downward force.

[0022] Optionally, second guide posts are arranged on the side of the fixing plate in the horizontal direction. A sliding block is fixedly disposed at the end of the waist-shaped guide hole through which the guide rod passes. Second guide through grooves are formed in the sliding block for the second guide posts to penetrate. A second compression spring in a compressed state is sleeved on the outer periphery of the second guide post, and the second compression spring is used to push the sliding block to slide in the direction of rotation of the pneumatic gripper.

[0023] By adopting the above technical solution, during the process of adjusting the rotation angle of the support plate and the pneumatic gripper, due to the cooperative setting of the second guide post and the second compression spring, it plays a buffering role in the horizontal direction, thereby reducing the possibility of deformation or damage of the terminal or the terminal block caused by excessive reset force when the pneumatic gripper is reset.

[0024] Optionally, a pressing component is provided on the processing table between the second clamping component and the third clamping component; the pressing component includes a pressing power source and a pressing block located above the terminal block, and the pressing power source is used to drive the pressing block to reciprocate in a direction close to the terminal block.

[0025] By adopting the above technical solution, when the parallel component is only fixedly connected to the terminal by clamping, and after this parallel component is placed on the upper side of the terminal under the action of the second clamping part, the parallel component moves to directly below the pressing block along with the terminal block. At this time, the pressing power source can be started, and the pressing block is used to press the parallel component, so that the parallel component is fixedly connected to the corresponding terminal.

[0026] A fully automatic plugging and assembling method for a terminal block includes the above-mentioned fully automatic plugging and assembling machine for a terminal block, and the assembling steps are as follows:

[0027] S1: Feed the terminal block through the terminal block feeding component;

[0028] S2: Feed the voltage terminal through the first feeding component in the voltage terminal assembling area;

[0029] S3: Install the voltage terminal onto the terminal block through the first clamping component in the voltage terminal assembling area;

[0030] S4: When installing a voltage terminal that needs to be added with an end cap, pre-assemble the voltage terminal and the end cap through the clamping component in the voltage terminal assembling area, and then install the assembled voltage terminal and end cap onto the terminal block through the first clamping component in the voltage terminal assembling area;

[0031] S5: Install the voltage parallel component onto the voltage terminal through the second clamping component in the voltage terminal assembling area;

[0032] S6; Install the insulating spacer between adjacent voltage parallel components through the third clamping component in the voltage terminal assembling area;

[0033] S7: Feed the current terminal through the first feeding component in the current terminal assembling area;

[0034] S8: Install the current terminal onto the terminal block through the first clamping component in the current terminal assembling area;

[0035] S9: When installing a current terminal that needs to be added with an end cap, pre-assemble the current terminal and the end cap through the clamping component in the current terminal assembling area, and then install the assembled current terminal and end cap onto the terminal block through the first clamping component in the current terminal assembling area;

[0036] S10: Install the current parallel component onto the current terminal through the second clamping component in the current terminal assembling area;

[0037] S11; Install the insulating spacer between adjacent current parallel components through the third clamping component in the current terminal assembly area;

[0038] The order of steps S2 - S6 and steps S7 - S11 can be interchanged.

[0039] By adopting the above technical solution, due to the application of the assembly method, the assembly and fixation of the voltage terminal and the terminal block, and the current terminal and the terminal block are realized. At the same time, the automatic installation of the parallel components and the insulating partition is also realized.

[0040] In summary, the present application includes at least one of the following beneficial technical effects:

[0041] 1. During the process of installing the terminal on the terminal block, the installation and fixation of the voltage terminal, the voltage parallel component and the insulating spacer are realized through the first feeding component, the first clamping component, the clamping component and the third clamping component; thereby realizing the automatic assembly of the terminal row, improving the assembly efficiency of the terminal row, and reducing the assembly cost of the terminal row.

[0042] 2. Due to the layout of the support rod and the receiving plate, when the terminal on the uppermost receiving plate is picked up, the driving member drives the transmission chain to act, so that the lower receiving plate rotates upward; making more reasonable use of the three-dimensional space, thereby reducing the overall occupied space of the first feeding component, and reducing the costs of transportation, installation and future maintenance management.

[0043] 3. Due to the installation of the pneumatic gripper and the adjustment component, when the pneumatic gripper fixes the clamped terminal on the terminal block, the gradual clamping of the terminal and the terminal block is realized, and the design of gradually clamping reduces the damage to the terminal and the terminal block during the installation process, thereby extending their service life.

[0072] Referring to Figure 9 andFigure 10 On the side of the fixed plate 413, an adjusting assembly 43 is provided for adjusting the rotation angle of the pneumatic gripper 411. The pneumatic gripper 411 can be rotated and adjusted along the vertical plane and fixed. The adjusting assembly 43 includes a support plate 431 slidably disposed on the vertical side of the fixed plate 413 and an adjusting cylinder 432 fixedly disposed on the vertical side of the fixed plate 413 in the vertical direction. The end of the telescopic rod of the adjusting cylinder 432 is hinged to the side of the support plate 431 away from the processing table 1;

[0073] On the side of the support plate 431, a guide rod 4311 is fixedly provided. On the fixed plate 413, a waist-shaped guide hole 4131 is provided for the guide rod 4311 to penetrate and slide, and the length direction of the waist-shaped guide hole 4131 is parallel to the upper side of the processing table 1 (see Figure 8 ). When the adjusting cylinder 432 operates, it can drive the guide rod 4311 to slide along the length direction of the waist-shaped guide hole 4131, and the guide rod 4311 rotates around its own axis.

[0074] Refer to Figure 10 and Figure 11 , the fixed plate 413 is slidably disposed on the vertical side of the mounting plate 412; on the side of the fixed plate 413, two first guide posts 4132 are provided along the height direction. On the mounting plate 412, a first guide through slot 4121 is provided for the first guide posts 4132 to penetrate and slide; a first compression spring 44 in a compressed state is sleeved on the outer periphery of the first guide posts 4132, and the first compression spring 44 is located on the side of the receiving plate 35 facing the processing table 1 (see Figure 8 ).

[0075] When the pneumatic gripper 411 drives the clamped terminal to move towards the terminal block, due to the installation of the first compression spring 44, it plays a buffering role during the vertical movement, reducing the possibility of deformation or damage to the terminal or the terminal block caused by excessive downward force.

[0076] Refer to Figure 10 and Figure 11 , on the side of the fixed plate 413, two second guide posts 4133 are provided along the horizontal direction. At the end of the waist-shaped guide hole 4131 through which the guide rod 4311 penetrates, a sliding block 45 is fixedly provided.

[0077] During the process of adjusting the rotation angle of the pneumatic gripper 411, due to the installation of the second compression spring 46, it plays a buffering role in the horizontal direction, thereby reducing the possibility of deformation or damage to the terminal or the terminal block caused by excessive reset force when the pneumatic gripper 411 rotates and resets.

[0078] Reference Figure 12 , the second clamping component 6 is used to clamp and fix the parallel component to be installed on the upper side of the terminal, which will not be elaborated here; a pressing component 8 is provided on the processing table 1 between the second clamping component 6 and the third clamping component 7; a fixing arm 14 is fixedly arranged on the processing table 1 on the side of the terminal block. The pressing component 8 includes a pressing power source 81 and a pressing block 82 located above the terminal block. The pressing power source 81 is a second vertical cylinder 811 installed vertically on the fixing arm 14, and the upper end of the telescopic rod of the second vertical cylinder 811 is fixedly connected to the pressing block 82. When the second vertical cylinder 811 operates, it can drive the pressing block 82 to reciprocate in the direction close to the terminal block;

[0079] Since the parallel component does not need to be fastened with screws and only needs to be fixed by pressing and clamping; when such a parallel component is placed on the upper side of the terminal under the action of the second clamping component, the parallel component moves with the terminal block to directly below the pressing block 82. At this time, the second vertical cylinder 811 can be started, and the pressing block 82 is used to press the parallel component to realize the clamping and fixing of the parallel component to the corresponding terminal.

[0080] Multiple terminals fixed by the same parallel component form a wiring unit. The third clamping component 7 is used to insert an insulating partition into the gap between adjacent wiring units. These insulating partitions can effectively separate different wiring units and prevent short circuits between different circuits. The specific structure of the third clamping component 7 will not be elaborated here.

[0081] A fully automatic plugging and assembling method for a terminal block includes the above-mentioned fully automatic plugging and assembling machine for a terminal block, and the assembling steps are as follows:

[0082] S1: Feed the terminal block through the terminal block feeding component 2;
