Description

Technical Field

[0001] This application relates to the technical field of terminal feeding, and in particular to a terminal feeding device. Background Technology

[0002] Terminal blocks, as an important component in electrical connections, typically include terminal blocks, multiple terminals, and parallel connectors for connecting adjacent terminals. In automated assembly, terminals are fed one by one to designated positions by a feeding assembly, and then clamping assemblies install them into the terminal blocks.

[0003] There are already various terminal feeding solutions in the existing technology. For example, Chinese patent with authorization publication number CN1958968A discloses a fully automatic terminal block insertion and assembly machine, which drives the transmission gear to rotate through the drive component, and the transmission gear drives the transmission chain to rotate. The transmission chain drives multiple feeding seats to rotate in a cycle, so as to realize the continuous feeding of terminals.

[0004] However, the existing feeding components have certain limitations in practical applications. Because they use a transmission gear drive transmission chain structure, the gap between the two oppositely set feeding seats is limited by the gear diameter, resulting in a large space occupied by the overall structure on the processing table. This not only increases the cost of equipment installation, transportation and maintenance, but also limits its application flexibility in compact automated equipment. Summary of the Invention

[0005] To reduce the space occupied by the feeding components in automated equipment, a terminal feeding device is provided.

[0006] The above-mentioned objective of this application is achieved through the following technical solution: A terminal feeding device includes a feeding assembly, the feeding assembly including two guide frames arranged opposite each other, guide grooves respectively opened on opposite sides of the two guide frames, a material picking position and a plurality of feeding positions arranged in the guide groove along the horizontal and vertical directions; The feeding position is provided with a sliding support block, the outer walls of two adjacent support blocks abut against each other, and the outer wall of the support block abuts against the inner wall of the guide groove. A feeding seat is provided between the support blocks arranged opposite to each other in the two guide frames, and the feeding seat has a feeding cavity into which the feeding terminal is inserted. It also includes a support frame located on one side of the guide frame, the support frame being provided with a drive assembly, the drive assembly being used to drive the support block to move along the inner edge of the guide groove, so that the designated feed seat reaches or leaves the material picking position.

[0007] By adopting the above technical solution, multiple support blocks are closely arranged in the feeding position of the guide groove to form a high-density storage array. When feeding is required, the drive component drives a specific support block to move along the path defined by the inner edge of the guide groove, moving the feeding seat it carries to the unique picking position. The precise, short-distance sliding of the support block along the fixed groove edge replaces the large rotation path of the traditional chain drive, shortening the travel time and distance of a single feeding seat from the feeding position to the picking position, thus improving feeding efficiency. It also eliminates the large structural gaps that are inevitably caused by the transmission chain and large transmission gears, allowing adjacent feeding seats to be closely adjacent, greatly compressing non-functional space, thereby solving the fundamental problem of large space occupation as a whole, making the equipment structure compact, and reducing manufacturing, transportation, and maintenance costs.

[0008] Preferably, the support block has a through transmission hole along the installation direction of the feeding seat, and the drive assembly includes: The first transmission cylinder and the second transmission cylinder are both mounted on the support frame, and the extension and retraction direction of their piston rods are aligned with the axis of the transmission hole. A horizontal drive mechanism is used to drive the first transmission cylinder to move in the horizontal direction, so as to move the upper support block to the material picking position, or to move the lower support block to the horizontally adjacent material feeding position. A vertical drive mechanism is used to drive the second transmission cylinder to move in the vertical direction, so as to move the support block to the vertically adjacent feeding position.

[0009] By adopting the above technical solution, the first transmission cylinder docks with the target support block and is driven to move horizontally by the horizontal drive mechanism, completing the loading and unloading of the feeding seat at the material picking position and the horizontal position adjustment; subsequently, the second transmission cylinder docks with the target support block and is driven to move vertically by the vertical drive mechanism, rearranging the support block array into a vertical array; through the step-by-step coordinated action of the horizontal and vertical drive mechanisms, matrix-style precise management of the compact silo is achieved, decomposing the feeding action into two precisely coordinated steps: horizontal repositioning and vertical compensation. This not only achieves precise driving of any support block, but also fundamentally improves space utilization and feeding cycle time, which is the key to achieving compactness and high efficiency of the device.

[0010] Preferably, the guide frame is provided with support frames on both sides, and each of the two support frames is provided with a set of driving components, and the two sets of driving components are arranged opposite to each other.

[0011] By adopting the above technical solution, when the support block needs to be moved, the drive components on both sides of the support frame receive a synchronization signal, and the piston rods of the first and second transmission cylinders on both sides of the feeding component extend simultaneously and are precisely inserted into the transmission holes in the support blocks of the two guide frames. Then, the support block moves synchronously, realizing balanced drive and support for the feeding seat assembly. This avoids the bending moment that may be generated by unilateral force, thereby effectively preventing the feeding seat from tilting or jamming during movement, and significantly improving the stability, reliability and mechanical life of the entire system.

[0012] Preferably, a guide rod is fixedly connected to the support frame, and a sliding member is slidably disposed on the guide rod, with the second transmission cylinder fixedly mounted on the sliding member.

[0013] By adopting the above technical solution, and by mounting the second transmission cylinder on a sliding member guided by a guide rod, its movement trajectory is strictly limited to a vertical straight line. This ensures that the driving force is always transmitted along the axial direction of the guide rod during the entire process of driving the support block to move vertically. This effectively eliminates lateral force components or offset tendencies, ensuring that the force applied by the vertical drive mechanism is always consistent with the direction of force movement of the support block. This prevents movement jamming and ensures the reliability of the support block's high-density, high-frequency operation in a compact space.

[0014] Preferably, a guide seat is fixedly connected to the sliding member, and a guide hole is provided on the guide seat, through which the piston rod of the second transmission cylinder passes.

[0015] By adopting the above technical solution, the guide seat provides an effective intermediate support for the slender piston rod, transforming it into a simply supported beam structure, which fundamentally enhances the structural rigidity of the piston rod and prevents instability and deformation. Secondly, the guide seat ensures the linear motion trajectory of the piston rod, enabling the piston rod to be accurately aligned and inserted into the transmission hole, ensuring that each driving action can be completed accurately and reliably.

[0016] Preferably, a guide rail seat is fixedly connected to the side of the support frame facing away from the guide frame. The guide rail seat is arranged along the horizontal sliding direction of the support block, and the first transmission cylinder is slidably arranged on the guide rail seat.

[0017] By adopting the above technical solution, the guide rail seat strictly constrains the movement path of the first transmission cylinder to an ideal straight line, eliminating the deviation caused by gaps and uneven friction. This ensures that the first transmission cylinder always has high motion repeatability and trajectory consistency in high-speed, high-frequency reciprocating motion. Precise horizontal movement is the basis for the support block to achieve interference-free and rapid posture switching in a compact space, providing a key guarantee for the efficient and reliable operation of the entire feeding device.

[0018] Preferably, it also includes two opposing support frames, two guide frames are fixedly connected inside the two support frames, and a base frame is fixedly connected to the lower end of each of the two support frames. Multiple pulleys are provided below the base frame. The support frame is also fixedly connected to a lifting cylinder in the vertical direction. The piston rod end of the lifting cylinder is fixedly connected to an active lifting seat. A passive lifting seat is fixedly provided on the outer wall of the support frame. The bottom of the passive lifting seat has an open notch. It also includes a lifting rod that passes through the active lifting seat and the support frame in sequence and is inserted into the notch. Furthermore, a photoelectric sensor electrically connected to the lifting cylinder is provided on one side of the feeding assembly along its sliding direction.

[0019] By adopting the above technical solution, in the actual installation process, the support frame and photoelectric sensor are fixed on the processing table. The terminal assembly operation can be realized by simply pushing and pulling the feeding component. After the operator pushes the feeding component to the target station, the feeding component triggers the photoelectric sensor on its side. The photoelectric sensor sends a signal to the control system, and the control system starts the lifting cylinder. The piston rod of the lifting cylinder extends, and the support frame and the entire feeding component are lifted up by the combined action of the active lifting seat and the passive lifting seat until the pulley is off the ground. This achieves seamless and automatic switching between the working state and the moving state of the equipment, and eliminates any slight drift or vibration caused by the contact between the pulley and the ground during precision material picking operations. This provides extremely high positioning stability and repeatability for automated production.

[0020] Preferably, the upper end of the guide frame is open, one side of the support frame is rotatably provided with a movable rod that can cover the open end of the guide frame, and the other side of the support frame is fixedly connected with a fastener for locking the movable rod.

[0021] By adopting the above technical solution, the movable rod and the fastening component together form a protective structure that can be quickly opened and closed. When the movable rod rotates to cover the upper opening of the guide frame and is locked by the fastening component, it can effectively prevent foreign objects from falling into the guide groove, avoid interference or jamming of the sliding of the support block, and ensure the reliability of the feeding device in complex industrial environments. At the same time, this design provides a convenient top operation channel for the installation, debugging and maintenance of the support block and the feeding seat, simplifies the operation process and improves the maintainability of the equipment.

[0022] Preferably, the bottom of the support block is provided with a guide slope.

[0023] By adopting the above technical solution, when the drive component drives the support block to move vertically upward, the bottom of the horizontally adjacent support block is provided with a guide slope to provide redundant space, avoiding the risk of motion interference and jamming caused by rigid contact between the top of the support block and the bottom of the horizontally adjacent support block. The setting of the guide slope ensures the absolute reliability of vertical movement in the dense array without sacrificing the overall layout density.

[0024] Preferably, a gap is left between the feed seats on adjacent support blocks.

[0025] By adopting the above technical solution, when a feeder is driven to move, the tiny gap between it and the adjacent feeder ensures that their structural boundaries will not physically contact or rub against each other during the entire movement process. While ensuring the overall structural compactness, it provides an independent and interference-free movement space for each movement unit.

[0026] In summary, this application has at least the following beneficial effects: 1. By adopting a matrix layout in which support blocks are densely arranged in the guide groove and their outer walls abut against each other, the huge gaps that must exist in traditional chain drives to accommodate the rotation of the sprocket are eliminated. This micro-gap arrangement maximizes the storage density of the feed seat array, thereby compressing the overall structure of the device to the extreme, significantly reducing the space occupied on the automated production line, and providing a basis for the miniaturization and compact design of the equipment. 2. Through the step-by-step coordinated action of the horizontal and vertical drive mechanisms, matrix-style precise management of the compact silo is achieved. The feeding action is decomposed into two precisely coordinated steps: horizontal repositioning and vertical compensation. This not only enables precise driving of any support block, but also fundamentally improves space utilization and feeding cycle time. The symmetrical drive components on both sides provide balanced driving force. Combined with a precision guide rail and guide rod system, it ensures that the support block moves without tilting or jamming in dense spaces. Attached Figure Description

[0029] The following section provides a more detailed description, in conjunction with the accompanying diagrams: As attached Figure 1 As shown, a terminal feeding device includes a feeding assembly 1 for storing terminals 2 to be fed. The feeding assembly 1 includes two opposing support frames 11. The support frames 11 can be made of metal, which has good strength and lightweight characteristics. Both support frames 11 are open on opposite sides. The lower ends of both support frames 11 are fixedly connected to a base frame 13. The base frame 13 is fixedly connected to the four sides of its lower part. The pulleys 131 can be casters. A push rod 14 is fixedly connected to one side of both support frames 11. Pushing the push rod 14 can drive the feeding assembly 1 to slide, which facilitates the movement and position adjustment of the feeding assembly 1.

[0030] As attached Figure 2 and attached Figure 3 As shown, a guide frame 12 is fixedly connected to each of the two support frames 11. The outline area of ​​the guide frame 12 is smaller than that of the support frame 11. Guide grooves 121 are opened on opposite sides of the two guide frames 12. The upper end of the guide frame 12 is open. A movable rod 3 is provided on one side of the upper end of the support frame 11, which rotates through a pin. The movable rod 3 can cover the upper opening of the guide frame 12 when it rotates towards the guide frame 12. A fastener 4 is fixedly connected to the other side of the support frame 11. The fastener 4 can quickly lock the movable rod 3 when it covers the upper opening of the guide frame 12. The movable rod 3 and the fastener 4 together form a protective structure that can be opened and closed quickly.

[0031] The guide groove 121 contains a material picking position 122 and multiple material feeding positions 123 arranged in the horizontal and vertical directions. The material feeding positions 123 are arranged in two rows, with several material feeding positions 123 in each row. The material picking position 122 is located at the upper end of one of the rows of material feeding positions 123. Each material feeding position 123 is provided with a support block 15 that can slide in the horizontal or vertical direction. The material of the support block 15 is the same as that of the support frame 11. The outline area of ​​the support block 15 is the same as that of the material feeding position 123. The support block 15 has a through transmission hole 152 along the installation direction of the material feeding seat 16. The outer walls of two adjacent support blocks 15 abut against each other. The outer wall of the support block 15 abuts against the inner wall of the guide groove 121. Thus, the two rows of support blocks 15 are arranged in an array in the guide groove 121.

[0032] The bottom of the support block 15 is provided with a guide slope 151. When one column of support blocks 15 moves vertically upward, the guide slope 151 at the bottom of the other column of support blocks 15 provides redundant space, avoiding the risk of motion interference and jamming caused by rigid contact between the top of one column of support blocks 15 and the bottom of the other column of support blocks 15. The setting of the guide slope 151 ensures the absolute reliability of vertical movement in a dense array without sacrificing the overall layout density.

[0033] As attached Figure 3 and attached Figure 4 As shown, a feeding seat 16 is provided between the support blocks 15 arranged opposite to each other in the two support frames 11. The feeding seat 16 is box-shaped and has a feeding cavity 161 for inserting the terminal 2. The terminal 2 can be stably placed in the feeding cavity 161. There are gaps between adjacent feeding seats 16 in the horizontal and vertical directions. When a feeding seat 16 is driven to move, the small gap between it and the adjacent feeding seat 16 ensures that their structural boundaries will not physically contact or rub against each other during the entire movement process. While ensuring the overall structural compactness, it provides an independent and interference-free movement space for each movement unit.

[0034] As attached Figure 1 and attached Figure 4As shown, the two ends of the feeding base 16 are the inlet end 162 and the outlet end 163, respectively. A limiting plate 17 is fixedly connected to the support frame 11 near the outlet end 163. The limiting plate 17 is located above the outlet end 163 and presses against the terminal 2 below. The limiting plate 17 is driven by a cylinder to move along the installation direction of the feeding base 16. A discharge gap is preset between the limiting plate 17 and the outlet end 163. A pushing member 18 is fixedly connected to the support frame 11 near the inlet end 162. The pushing member 18 is used to push the terminal 2 in the feeding chamber 161 from the inlet end 162. 2. Pushing towards the discharge end 163, the operator can pre-place the terminal 2 to be assembled into the feeding chamber 161. Due to the setting of the pusher 18 and the limiting plate 17, the mechanical claw grabs the terminal 2 located in the discharge gap. At the same time, the limiting plate 17 prevents the terminal 2 located in the discharge gap from being pulled out by the friction of the adjacent terminal 2. After the mechanical claw grabs the terminal 2 in the feeding chamber 161, the pusher 18 is used to push the remaining terminal 2 in the feeding chamber 161 towards the discharge end 163, so as to prevent the remaining terminal 2 from being scattered.

[0035] As attached Figure 6 and attached Figure 7 As shown, support frames 5 are provided on both sides of the support frame 11. The gap between the two support frames 5 allows the entire feeding assembly 1 to slide in. The two support frames 5 are fixedly installed on the work frame during actual operation. Each of the two support frames 5 is provided with a set of driving components 6. The two sets of driving components 6 are arranged opposite to each other, so that the two driving components 6 can drive the support blocks 15 in the two guide frames 12 from both sides to move.

[0036] The drive assembly 6 includes a first transmission cylinder 61 and a second transmission cylinder 62. The first transmission cylinder 61 and the second transmission cylinder 62 are arranged in a direction perpendicular to the support frame 11. The extension and retraction direction of the piston rods of the first transmission cylinder 61 and the second transmission cylinder 62 are aligned with the axis of the transmission hole 152. The first transmission cylinder 61 and the second transmission cylinder 62 can be ordinary pneumatic cylinders, which facilitates the adjustment of the extension and retraction speed of the piston rods of the first transmission cylinder 61 and the second transmission cylinder 62. The support frame 5, the support frame 11 and the guide frame 12 are respectively provided with transmission grooves 7 for the piston rods of the first transmission cylinder 61 and the second transmission cylinder 62 to pass through and slide. The transmission grooves 7 provide a channel for the reciprocating motion of the piston rods of the first transmission cylinder 61 and the second transmission cylinder 62.

[0037] The drive assembly 6 also includes a horizontal drive mechanism 63 and a vertical drive mechanism 64. The horizontal drive mechanism 63 is actually a horizontal drive cylinder. The horizontal drive mechanism 63 is installed on the top and bottom of the two side support frames 11. The first transmission cylinder 61 is also located on the top and bottom of the two side support frames 11. When a new feed seat 16 needs to be sent to the picking position 122, the control system first determines the position of the target support block 15. Then, the horizontal drive mechanisms 63 on both sides drive the first transmission cylinder 61 to move and align with the target column. The piston rod of the first transmission cylinder 61 extends and inserts into the transmission hole 152 of the uppermost support block 15 of the column, pushing it horizontally into the adjacent picking position 122.

[0038] A guide rail seat 51 is fixedly connected to the side of the support frame 5 facing away from the support frame 11. There are four guide rail seats 51 here, which are fixedly connected to the top and bottom of the two support frames 11 respectively. The guide rail seats 51 are arranged along the horizontal sliding direction of the support block 15, and the first transmission cylinder 61 is slidably arranged on the guide rail seat 51. The guide rail seat 51 can be a metal guide rail, such as a channel steel guide rail. The sliding of the first transmission cylinder 61 on the guide rail seat 51 provides support and guidance for its horizontal movement.

[0039] The vertical drive mechanism 64 is actually a vertical drive cylinder. There are four vertical drive mechanisms 64 here. Each support frame 5 is provided with two vertical drive mechanisms 64 along the vertical direction. The two vertical drive mechanisms 64 on a single support frame 5 are respectively aligned with the two rows of support blocks 15. Four guide rods 52 are fixedly connected to the bottom of the support frame 5. The guide rods 52 can be cylindrical metal rods. Sliding elements 65 are slidably arranged on the guide rods 52. One side of the sliding element 65 is plate-shaped and fixedly connected to the second transmission cylinder 62. The other side of the sliding element 65 is sleeve-shaped and slidably arranged inside the guide rod 52. Each sliding element 65 slides on two guide rods 52 respectively.

[0040] The top ends of the four guide rods 52 are also fixedly connected to fixed plates 53 that provide support for the two vertical drive mechanisms 64. The second transmission cylinder 62 is fixedly connected to the lower part of the sliding member 65. The output ends of the two vertical drive mechanisms 64 are fixedly connected to the upper part of the sliding member 65. The vertical drive mechanism 64 drives the second transmission cylinder 62 to descend, so that its piston rod is aligned with the support block 15 at the bottom of the column and pushes it upward one station to move the support block 15 to the vertically adjacent feeding position 123. This ensures that during the entire process of driving the support block 15 to move vertically, the driving force is always transmitted axially along the guide rod 52, so that the force applied by the vertical drive mechanism 64 is always consistent with the direction of force movement of the support block 15.

[0041] As attached Figure 7 and attached Figure 8As shown, a guide seat 66 is also fixedly connected below the sliding member 65. The guide seat 66 is set perpendicular to the support frame 11. There are four guide seats 66 here. The four guide seats 66 are respectively aligned with the second transmission cylinder 62. The guide seat 66 has a guide hole 661 through which the piston rod of the second transmission cylinder 62 passes. The guide hole 661 guides the movement of the piston rod, ensuring the linear movement trajectory of the piston rod, so that the piston rod can be accurately aligned and inserted into the transmission hole 152, ensuring that each driving action can be completed accurately and reliably.

[0042] As attached Figure 9 and attached Figure 10 As shown, passive lifting seats 111 are fixedly installed on the opposite sides of the two support frames 11. Here, two passive lifting seats 111 are fixedly connected to a single support frame 11 in the vertical direction. Each passive lifting seat 111 is preferably a block of metal and is fastened to the support frame 11 by bolts. Each passive lifting seat 111 has an open notch at the bottom, with the opening facing downwards. Its cross-sectional shape can be U-shaped, V-shaped, or rectangular.

[0043] A lifting cylinder 54 is also fixedly connected to the side of the support frame 5 facing away from the support frame 11 in the vertical direction. Here, a single support frame 5 is provided with two lifting cylinders 54. The piston rod of the upper lifting cylinder 54 extends vertically upward, and the piston rod of the lower lifting cylinder 54 extends vertically downward. The end of the piston rod of each lifting cylinder 54 is fixedly connected to an active lifting seat 541. Thus, the lifting cylinder 54 can drive the active lifting seat 541 to move up and down through the piston rod.

[0044] A lifting rod 542 is also provided between the active lifting seat 541 and the passive lifting seat 111. The lifting rod 542 is a rigid long rod that passes horizontally through the pre-set through holes on the active lifting seat 541 and the support frame 5. When the piston rod of the lifting cylinder 54 extends, it drives the active lifting seat 541 to move up or down. At this time, the operator then passes the lifting rod 542 through the active lifting seat 541 and the support frame 5 and inserts it into the notch at the bottom of the passive lifting seat 111. Thus, the up and down movement of the active lifting seat 541 driven by the lifting cylinder 54 can be converted into the up and down movement of the passive lifting seat 111 by the lifting rod 542, thereby realizing the lifting of the entire feeding assembly 1.

[0045] A connecting plate 8 is also provided on one side of the feeding component 1 along its sliding direction. The connecting plate 8 is also fixed on the processing table, and two photoelectric sensors 9 are fixedly connected to the connecting plate 8. The photoelectric sensors 99 are used to detect whether the feeding component 1 is pushed in. After the feeding component 1 is pushed in, the corresponding lifting cylinder 54 will be activated. Through the coordinated action of the active lifting seat 541 and the passive lifting seat 111, the support frame 11 and the entire feeding component 1 will be lifted until the pulley 131 is off the ground, realizing seamless and automatic switching between the working state and the moving state of the equipment.

[0046] The implementation principle of this embodiment is as follows: The feeding assembly 1 has two opposing guide frames 12, with multiple slidable support blocks 15 densely arranged in the guide grooves 121. The outer walls of adjacent support blocks 15 abut against each other, forming a compact matrix of feeding positions 123. The support blocks 15 are connected by a feeding seat 16, and the feeding cavity 161 on the feeding seat 16 is used to accommodate the terminal 2. The driving assembly 6 includes a first transmission cylinder 61 and a horizontal driving mechanism 63, and a second transmission cylinder 62 and a vertical driving mechanism 64, which work together in a step-by-step manner in the horizontal and vertical directions. The mechanism drives the designated support block 15 to move along the inner edge path of the guide groove 121, thereby accurately delivering the target feeding seat 16 to the picking position 122. This structure replaces the large rotational motion of the traditional chain drive with the short-range linear sliding of the support block 15, fundamentally eliminating the structural gap required by the chain drive and greatly compressing the non-functional space. At the same time, through the dual-sided symmetrical drive and precision guiding mechanism, it ensures the smoothness of movement and positioning accuracy under dense arrangement, realizing the synergistic optimization of the feeding device in terms of space occupation and operating efficiency.

[0047] This specific embodiment is merely an explanation of this application and is not intended to limit it. 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 fall within the scope of protection claimed in this application.
