Description

Technical Field

[0001] This invention relates to the field of terminal block technology, and more particularly to a terminal block pin manufacturing equipment. Background Technology

[0002] As a core component in the field of electrical connections, terminal blocks are widely used in many fields such as industrial automation, automotive electronics, home appliances, and rail transportation. The processing accuracy of their pins directly determines the reliability of insertion and removal, conductivity stability, and assembly compatibility of the terminal blocks, which is a key factor affecting the quality of end products.

[0003] As electronic devices evolve towards miniaturization, high precision, and integration, the market demands increasingly stringent processing requirements for terminal block pins. This necessitates not only ensuring the coaxiality and bending angle consistency between the pin and the pin body, but also balancing efficiency and stability in mass production. However, the current industry standard for terminal block pin production still predominantly employs a segmented processing method, resulting in the following significant technical challenges: In traditional production, horizontal guide channels are often used for feeding. Due to factors such as trace amounts of oil on the surface of metal parts, electrostatic adsorption, and mechanical interference, pins are prone to accumulate and get stuck in the guide channel, causing feeding interruptions. This requires frequent manual shutdowns for cleaning, which seriously affects the continuity of production. The pin insertion process lacks precise positioning and coordinated fixing mechanisms, relying heavily on manual visual alignment or simple tooling assistance. This makes it difficult to ensure coaxial alignment between the pin and the preset hole position on the pin body, which can easily lead to defects such as misalignment, shallow insertion, and pin skew. The coaxiality error of the insertion can reach more than ±0.1mm, resulting in poor contact and difficulty in insertion and removal during product assembly. The bending process often uses a single cylinder to directly push or manually hammer to form the pin. The bending torque transmission is unstable, and the contact surface between the bending component and the pin is mostly flat or sharp, resulting in poor consistency of the pin bending angle. At the same time, local pressure concentration can easily cause indentation, chipping, or plastic deformation on the pin surface, which seriously affects the assembly compatibility and service life of the terminal block.

[0004] To address the above problems, this invention proposes a terminal block pin manufacturing device. Summary of the Invention

[0009] Preferably, the adjusting device includes a locking plate that engages with the surface of the guide plate. The main body of the locking plate has an array of mounting slots that match the number of grooves opened at the upper end of the guide plate. A pressing rod is slidably connected inside the mounting slot. A retaining ring is fixedly connected to the lower end of the pressing rod.

[0010] Preferably, the upper outer surface of the pressing rod is provided with a knurled structure, the upper top surface of the pressing rod is provided with a pointer, and the upper end of the card plate is provided with a scale around each of the mounting slots.

[0011] Preferably, both the guide plate and the needle feeding device are inclined at a 10-degree angle to the horizontal. The needle feeding device includes an upper slide plate, and a lower slide plate is fixedly connected to the lower end of one side of the upper slide plate.

The outer surface of the auxiliary cylinder is fixedly connected to the lower surface of the upper slide plate. One end of the lower slide plate is flush with the side of the processing tube.

[0012] Preferably, a miniature vibrator is attached to the lower surface of the guide plate.

[0013] Preferably, the bending mechanism includes a fixing ring that is fixedly sleeved on the outer surface of the processing tube, a slider that slides circumferentially between the two fixing rings, a bending strip provided at the upper end of one side of the slider, the two ends of the bending strip being rotatably connected to the surface of the fixing ring through bearings, the lower middle position of the bending strip being rotatably hinged to the upper end of the slider, the outer surface of one end of the slider being set as a toothed surface, the toothed surface of the slider engaging with a rack, and a bending cylinder being fixedly connected to one end of the rack.

[0014] Preferably, a rectangular groove adapted to the pin is provided on one side of the processing tube.

[0015] The beneficial effects of this invention are as follows: 1. By setting up a pin insertion mechanism, the pin feeding mechanism, together with a 10-degree inclined guide plate and a bottom micro vibrator, utilizes the synergistic effect of gravity and vibration to break the adhesion between pins, avoiding material jamming and significantly improving feeding smoothness compared to traditional horizontal guide structures. The pressing rod of the adjustment device adopts a knurled structure, taking into account both anti-slip properties and comfort during manual operation. Combined with the scale and pointer on the plate, operators can intuitively and accurately adjust the position of the limit rod, facilitating the blocking and releasing of pins in the chute. The air supply connector of the pin insertion plate can remove pins from the lower slide plate by sucking in and blowing air with an air pump. In conjunction with the lifting cylinder, pushing cylinder, and pressing cylinder, the pressing block is driven to press the pins, achieving coaxial alignment and insertion of the pins and the pin body, effectively improving the pin insertion qualification rate. Moreover, the entire process is automated, eliminating the need for manual step-by-step transfer of workpieces and significantly improving production efficiency.

[0016] 2. By setting up a bending mechanism, a bending cylinder drives the rack and pinion to mesh with the toothed surface of the slider. The rigid connection of the meshing transmission ensures that the bending torque is transmitted without lag. Combined with the smooth sliding of the slider in the annular groove of the fixed ring, the bending action is enhanced, and the bending angle of the pin is kept within a very small range. The bending strip is rotatably connected to the fixed ring through a bearing. Its contact end with the pin is designed to fit the outer surface of the pin, avoiding local pressure concentration during bending. This effectively prevents the pin from being indented, chipped, or plastically deformed. At the same time, the fit clearance between the slider and the annular groove reduces sliding friction loss and extends the service life of the bending mechanism. This solves the pain points of traditional bending equipment, such as reliance on manual positioning, large angle deviation, and high pin damage rate, and ensures the assembly adaptability of the pin after forming.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figures 1-8 A terminal block pin production device includes a support platform 1, a guide tube 2 on one side of the upper end of the support platform 1, a pin feeding machine 3 on one side of the guide tube 2, a processing tube 4 on the other side of the guide tube 2, a pin 5 slidably connected to the inner wall of the guide tube 2, a guide groove adapted to the outer surface of the pin 5 inside the processing tube 4, a main cylinder 6 on one side of the guide tube 2, a ejector pin 7 at one end of the main cylinder 6, one end of the ejector pin 7 slidably connected to the inner wall of the processing tube 4, a pin insertion mechanism 8 at the middle position of the processing tube 4, and a bending mechanism 9 on one side of the pin insertion mechanism 8.

[0021] The pin insertion mechanism 8 is used to insert pins into the body of pin 5.

[0022] The bending mechanism 9 is used to bend the pin 5.

[0023] In this embodiment, the pin insertion mechanism 8 includes a slave cylinder 81 disposed on one side of the processing tube 4. An L-shaped push rod 82 is fixedly connected to one end of the piston rod of the slave cylinder 81. The long rod end surface of the push rod 82 is slidably connected to the lower end surface of the processing tube 4. A pin feeding mechanism 84 is disposed on one side of the support platform 1. Pins are installed inside the pin feeding mechanism 84. A guide plate 83 is disposed at the outlet of the pin feeding mechanism 84. The upper surface of the guide plate 83 has an array of grooves adapted to the pins. An adjustment device 85 is disposed on one side of the upper surface of the guide plate 83. A pin feeding device 86 is fixedly connected to one end of the guide plate 83.

[0024] Specifically, a limiting protrusion is provided in the middle of the L-shaped push rod 82 to block the movement of the pin 5, forming an axial limit to prevent the pin 5 from moving during insertion. When the pin 5 moves to the blocking position, the cylinder 81 drives the push rod 82 to move. After the push rod 82 pushes the pin 5 into the inlet of the processing tube 4, the cylinder 81 drives the push rod 82 to return to its original position. The main cylinder 6 pushes the pin 5 to the insertion station. The pressing cylinder 810 drives the pressing block 812 to squeeze the pin 5. The main cylinder 6 maintains the pushing posture to facilitate secondary pushing to the bending mechanism 9. The pin feeding mechanism 84 adopts a hopper-type structure with layered partitions inside. Its outlet is precisely connected to the chute inlet of the guide plate 83 with a connection gap ≤0.1mm to ensure that the pin smoothly enters the chute.

[0025] In this embodiment, a pin insertion disk 87 is provided on the other side of the processing tube 4. One side of the pin insertion disk 87 has a slot adapted to the surface of the pin. An array of air supply connectors is installed on the upper surface of the pin insertion disk 87. One end of each air supply connector is connected to an air pump. The inner wall of the air outlet of the air supply connector is fixedly connected to the inner wall of the slot. A lifting cylinder 88 is fixedly connected to the lower surface of the pin insertion disk 87. A pushing cylinder 89 is provided on one side of the lifting cylinder 88. One end of the piston rod of the pushing cylinder 89 is... The upper end of the processing tube 4 is equipped with a pressing cylinder 810 in contact with one side of the pin plate 87. One end of the piston rod of the pressing cylinder 810 is fixedly connected to a pressing block 812. The pressing block 812 is slidably connected to the inner wall of the slot at the upper end of the processing tube 4. The lower surface of the pressing block 812 is pressed against the upper end of the pin 5 directly below it. The outer surface of the pressing cylinder 810 is fixedly fitted with a mounting bracket 811. The two ends of the mounting bracket 811 are fixedly connected to the upper surface of the processing tube 4.

[0026] Specifically, the number of slots in the pin insertion disk 87 is the same as the number of grooves in the guide plate 83. The inner wall of the slot is polished to avoid scratching the surface of the pin. The air supply connector first draws air through the air pump to push the pin supply device 86 to the slot entrance to attract and fix the pin, preventing displacement. The lifting cylinder 88 can precisely adjust the height of the pin insertion disk 87 so that the slot and the preset hole position of the pin 5 in the processing tube 4 are coaxially aligned. The pushing cylinder 89 pushes the pin of the pin insertion disk 87 to smoothly insert the pin 5. The pressing cylinder 810 drives the pressing block 812 to press the pin 5 with a pressure of 100~150N. The lower surface of the pressing block 812 is bonded with a silicone pad with a thickness of 0.5mm to avoid damaging the pin 5. After the pin insertion is completed, the air supply connector is switched to blowing air to assist the pin to demold from the slot and prevent sticking.

[0027] In this embodiment, the adjusting device 85 includes a locking plate 851 that engages with the surface of the guide plate 83. The main body of the locking plate 851 has an array of mounting slots that match the number of sliding grooves on the upper end of the guide plate 83. A pressing rod 852 is slidably connected inside the mounting slot. A retaining ring 853 is fixedly connected to the lower end of the pressing rod 852. A limiting ring 856 that matches the retaining ring 853 is fixedly connected to the inner wall of the mounting slot. The retaining ring 853 has a protruding end. One side of the limiting ring 856 is open. A bearing 854 is fixedly connected to the lower end of the pressing rod 852. A spring 855 is fixedly connected to the lower surface of the bearing 854. The lower end of the spring 855 is fixedly connected to the inner bottom wall of the mounting slot. A limiting rod 857 is fixedly connected to the lower surface of the outer ring of the bearing 854. The lower end of the limiting rod 857 matches the inner wall of the sliding groove.

[0028] Specifically, when the number of pins of pin 5 is confirmed, the above mechanism is adjusted by pressing down the pressing rod 852, compressing the spring 855, aligning the protruding end of the retaining ring 853 with the opening of the limiting ring 856, and then rotating the pressing rod 852. The pressing rod 852 drives the retaining ring 853 to rotate through the bearing 854, causing it to be misaligned with the opening of the limiting ring 856. This allows the lower end of the limiting rod 857 to be fully inserted into the groove of the guide plate 83, thereby adjusting the number of pins inserted.

[0029] In this embodiment, the upper outer surface of the pressing rod 852 is provided with a knurled structure, a pointer is provided on the upper top surface of the pressing rod 852, and a scale is provided around each mounting slot on the upper end of the card plate 851.

[0030] Specifically, the knurling structure at the upper end of the pressing rod 852 is a circular arc knurling with a module of 0.3~0.5mm. By aligning the pointer with the scale, the operator can precisely adjust the limit rod 857 after it enters the slot to ensure that the retaining ring 853 and the limit ring 856 are misaligned.

[0031] In this embodiment, both the guide plate 83 and the needle feeding device 86 are inclined at an angle of 10 degrees to the horizontal. The needle feeding device 86 includes an upper slide plate 861, and a lower slide plate 862 is fixedly connected to the lower end of one side of the upper slide plate 861. The bodies of the upper slide plate 861 and the lower slide plate 862 are provided with sliding holes that are adapted to the sliding groove of the guide plate 83. A rectangular through hole 863 is provided between two adjacent sliding holes in the vertical direction. The length and width of the rectangular through hole 863 are adapted to the surface of the lead needle. A needle feeding rod 864 is slidably connected to the inner wall of the sliding hole of the lower slide plate 862. An auxiliary cylinder 865 is fixedly connected to one end of the needle feeding rod 864. The outer surface of the auxiliary cylinder 865 is fixedly connected to the lower surface of the upper slide plate 861. One end of the lower slide plate 862 is flush with the side of the processing tube 4.

[0032] Specifically, the width of the groove of the guide plate 83 is 0.1~0.2mm larger than the diameter of the pin, and the groove depth is 1~2mm, to ensure that the pin slides smoothly along the groove; the length of the rectangular through hole 863 is 2~3mm longer than the pin, and the width is 0.05~0.1mm larger than the diameter of the pin, serving as a temporary pin storage and positioning function; the pin feeding rod 864 is made of hard alloy material, with a diameter of 3~5mm, and a V-shaped positioning groove is machined at the front end. The auxiliary cylinder 865 can accurately push the pin in the rectangular through hole 863 to the vicinity of the slot entrance of the pin tray 87, making it convenient for the pin tray 87 to pick up the pin.

[0033] In this embodiment, a micro vibrator is attached to the lower surface of the guide plate 83.

[0034] Specifically, the vibration frequency of the micro vibrator is 60~100Hz and the amplitude is 0.1~0.2mm. It works in conjunction with the tilt angle of the guide plate 83 to break the adsorption force between the pins by using the dual effects of gravity and vibration, thus avoiding material jamming. The vibrator adopts a waterproof and dustproof design and the vibration intensity can be adjusted by a PLC controller.

[0035] In this embodiment, the bending mechanism 9 includes a fixing ring 91 that is fixedly sleeved on the outer surface of the processing tube 4. A slider 92 slides circumferentially between the two fixing rings 91. A bending strip 93 is provided on the upper end of one side of the slider 92. The two ends of the bending strip 93 are rotatably connected to the surface of the fixing ring 91 through bearings. The lower middle part of the bending strip 93 is rotatably hinged to the upper end of the slider 92. The outer surface of one end of the slider 92 is set as a toothed surface. A rack 95 meshes with the toothed surface of the slider 92. A bending cylinder 94 is fixedly connected to one end of the rack 95.

[0036] Specifically, the fixing ring 91 is fixed to the processing tube 4 by bolts, and the slider 92 and the rack 95 mesh with each other to ensure that the bending torque is transmitted evenly and without obstruction. The free end of the bending bar 93 is provided with an arc-shaped groove that matches the outer surface of the pin 5. The bending cylinder 94 can drive the bending bar 93 to achieve a precise bending of 90°~180° through the cooperation of the rack 95 and the slider 92, thereby realizing the 90-degree bending of the pin.

[0037] In this embodiment, a rectangular groove adapted to the pin is provided on one side of the processing tube 4.

[0038] Specifically, the width of the rectangular groove is 0.05~0.1mm larger than the diameter of the pin, and the depth is 2~3mm. Its center line is aligned with the center line of the slot of the pin tray 87 to ensure that the pin passes smoothly through the rectangular groove and is inserted into the preset hole of the pin 5, avoiding jamming or offset when inserting the pin.

[0039] Reference Figures 1-8 A method for producing terminal block pins using a manufacturing equipment, comprising the following specific steps: Step 1: Press down on the pressing rod 852, compress the spring 855, align the protruding end of the retaining ring 853 with the opening of the limiting ring 856, then rotate the pressing rod 852. The pressing rod 852 drives the retaining ring 853 to rotate through the bearing 854, causing it to be misaligned with the opening of the limiting ring 856. This allows the lower end of the limiting rod 857 to be fully inserted into the groove of the guide plate 83, thereby adjusting the number of pins inserted. Then, the pin feeding machine 3 orderly conveys the pins 5 to be processed to the feed inlet of the guide tube 2. The pins 5 slide along the smooth guide surface of the inner wall of the guide tube 2 to the docking point with the processing tube 4. The cylinder 81 drives the push rod 82 to move. After the push rod 82 pushes the pins 5 into the inlet of the processing tube 4, the cylinder 81 drives the push rod 82 to return to its original state. The main cylinder 6 pushes the pins 5 to the pin insertion station. The pressing cylinder 810 drives the pressing block 812 to press the pins 5, and the main cylinder 6 maintains the pushing posture. Step 2: While Step 1 is being executed, the pins in the pin feeding mechanism 84, under the action of gravity and with the activation of the micro vibrator, enter the upper slide plate 861 along the slide groove of the guide plate 83. The pins slide sequentially into the rectangular through hole 863 of the pin supply device 86. The auxiliary cylinder 865 drives the pin feeding rod 864 to push the pins in the rectangular through hole 863 to the slot entrance of the pin insertion plate 87. The air supply connector of the pin insertion plate 87 draws in air, adsorbing and fixing the pins in the slot. The lifting cylinder 88 adjusts the height of the pin insertion plate 87 so that the slot is coaxially aligned with the rectangular groove of the processing tube 4. The pushing cylinder 89 pushes the pin insertion plate 87 to move towards the processing tube 4, inserting the pins through the rectangular groove into the preset hole of the pin 5. After the pin insertion is completed, the air supply connector blows air to release the adsorption and fixing action of the pins. At the same time, the pushing cylinder 89, the lifting cylinder 88, and the pressing cylinder 810 are reset sequentially, and the pin supply device 86 performs a second pin supply. Step 3: After the pin is inserted, the pin 5 moves to the working area of ​​the bending mechanism 9 under the continuous push of the main cylinder 6. The main cylinder 6 resets, and the bending cylinder 94 drives the rack 95 to move linearly. The rack 95 meshes with the toothed surface of the slider 92, driving the slider 92 to slide along the annular groove of the fixed ring 91. The slider 92 drives the bending strip 93 to rotate around the bearing of the fixed ring 91. The arc-shaped groove of the bending strip 93 fits the outer surface of the pin 5, completing the bending with uniform torque. After the bending is completed, the bending cylinder 94 resets, and the previously processed pin 5 slides out along the inner wall of the processing tube 4 under the push of the subsequent pin 5.
