Description

Technical Field

[0001] The present invention relates to the technical field of terminal contact component assembly, and more particularly to a terminal pin device. Background Art

[0002] The terminal block is an accessory product used to achieve electrical connection. It is classified as a connector in the industry. With the increasing degree of industrial automation and the increasingly stringent and precise requirements for industrial control, the use of terminal blocks is gradually increasing. Therefore, when the terminal contact component is inserted, the needle body needs to be placed in the specified position for extrusion molding to complete the assembly operation of the terminal contact component.

[0003] In the existing public documents, the patent announcement number CN116093708A discloses a combined type of automatic pin insertion equipment for terminal blocks. The pin insertion equipment mainly uses the pin vibration feeding mechanism to cooperate with the base conveying mechanism, the clamping mechanism and the pin pressing mechanism to combine into terminal blocks with different pins according to the needs, so as to improve the usability of the equipment; the pin vibration feeding mechanism cooperates with the mobile platform to clamp the pins, the base conveying mechanism bites the pins, and the pin pressing mechanism presses the pins into the plastic base, and the pins are inserted and assembled into finished products in sequence. This pin insertion machine has a simple structure, small size, light weight, can realize full-automatic pin insertion, and is quick and convenient to assemble, which doubles the assembly efficiency. However, the pin insertion equipment still has the following problems.

[0004] When assembling the terminal contact components for insertion, they need to be shaped and positioned by extrusion so that the pins are at the specified positions, thereby ensuring that the terminal contact components can be inserted according to the specified requirements during assembly. However, when some pin bodies of the terminal contact components are laterally offset or vertically offset during the shaping and positioning process, directly performing the shaping and positioning by extrusion will cause the positioning parts to be offset, thereby causing multiple pin bodies of the terminal contact components to be directly bent and damaged during the extrusion process, making it difficult to perform laterally spaced positioning and shaping of the multiple pin bodies of the terminal contact components, as well as to achieve vertically spaced positioning and shaping of the multiple pin bodies of the terminal contact components. The qualified rate of the terminal contact component pin assembly is greatly reduced, which requires improving the terminal contact component pin assembly technology, and for this purpose, a terminal pin insertion device is required.

[0014] Technical effects and advantages of the present invention:

[0015] 1. The present invention uses a vertical spacing positioning and shaping mechanism.

After the improvement, the assembly qualification rate of the terminal contact component pins is greatly improved.

[0016] 2. The present invention adopts a vertical spacing positioning and shaping mechanism. The controller starts the driving motor, and the driving motor drives the bidirectional screw to rotate. The bidirectional screw drives the two threaded sleeve blocks to approach each other under the action of the thread transmission force. The lower vertical shaping strip moves up along the outer wall of multiple vertical spacing strips and is squeezed on the lower surface of multiple needle bodies, while the upper vertical shaping strip can move down and be squeezed on the upper surface of multiple needle bodies. The linkage block drives the sliding frame to move right, and the sliding frame drives the bidirectional screw to move right. The upper vertical shaping strip moves right along the upper surface of multiple needle bodies for shaping and positioning, while the lower vertical shaping strip moves right along the lower surface of multiple needle bodies for shaping and positioning. In this way, multiple needle bodies and multiple shaping grooves can be accurately positioned and assembled, greatly improving the assembly qualification rate of the terminal contact component pins.

[0017] 3. The present invention uses a positioning and speed control component. When the upper vertical shaping strip can move downward and extrude on the upper surfaces of multiple needle bodies, the concave sleeve block is driven downward by the vertical shaping strip, and the linkage shaft drives the uniform speed roller to move downward and extrude on the upper surface position of one of the needle bodies. The linkage shaft drives the concave sleeve plate to make the guide column squeeze on the pressure sensor. When the pressure value sensed by the pressure sensor is the same as the pressure value set by the concave sleeve block, it is known that the upper vertical shaping strip is rotating according to the specified pressure, and the uniform speed roller drives the linkage shaft to rotate. The sleeve block realizes speed sensing through the speed sensor. The two vertical shaping strips can perform horizontal spacing shaping and positioning on multiple vertical spacer strips at the specified speed, ensuring that multiple needle bodies can be positioned and shaped inside the terminal, ensuring that multiple needle bodies can be accurately docked and assembled with multiple shaping grooves, ensuring that each assembly can be qualified, and greatly improving the assembly qualification rate of the terminal contact component pins.

[0018] According to the mutual influence of the above-mentioned multiple effects, firstly, multiple vertical spacers can be vertically moved, spaced, positioned and shaped for multiple needle bodies, then the upper vertical shaping strips are moved rightward along the upper surfaces of the multiple needle bodies for shaping and positioning, while the lower vertical shaping strips are moved rightward along the lower surfaces of the multiple needle bodies for shaping and positioning, and finally, the two vertical shaping strips can perform horizontal spacing and shaping positioning for multiple vertical spacers at a specified speed and specified contact pressure. In summary, the bending parts of multiple needle bodies can be automatically shaped, the multiple needle bodies of the terminal contact component can be spaced, positioned and shaped laterally, and the multiple needle bodies of the terminal contact component can be spaced, positioned and shaped vertically. After the improvement, the qualified rate of assembly of the terminal contact component pins is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The working principle of the terminal pin device of the present invention:

[0040] Step 1: During vertical spacing positioning and shaping, multiple terminals 17 are placed on the track on the upper surface of the inclined track 2 for tilted sliding, and multiple pins 18 can be inserted into the inner wall of the terminal 17. When there is a tilting and bending problem among the multiple pins 18, the electric cylinder 16 is started by the controller 25, and the electric cylinder 16 pushes the L-shaped support block 15 to move left, and the L-shaped support block 15 drives the support frame 12 to move left, and the support frame 12 makes the one-way screw 13 move left, and the one-way screw 13 drives the socket block 11 to move left, and the socket block 11 makes the linkage block 5 move left. At the same time, the linkage block 5 drives the linkage bar 6 to move left, and the linkage bar 6 approaches the side of the terminal 17, and the distance between the positioning distance sensor 7 and the terminal 17 can be sensed by the positioning distance sensor 7. When the distance value sensed by the positioning distance sensor 7 and the distance value set by the controller 25 are two centimeters, the multiple lateral pointed strips 10 can be located at adjacent intervals below the multiple needle bodies 18, and the vertical shaping strips 33 are located above the multiple needle bodies 18, and then the electric cylinder 16 is closed by the controller 25.

[0041] The reduction motor 14 is started through the controller 25, and the reduction motor 14 drives the one-way screw 13. The one-way screw 13 drives the sleeve block 11 to move upward under the action of the thread transmission force, and the sleeve block 11 drives the linkage block 5 to move upward, and the linkage block 5 drives the linkage bar 6 to move upward, and the linkage bar 6 can drive multiple vertical spacer bars 8 to move upward, and the vertical spacer bars 8 drive the lateral pointed bars 10 to move upward, and the lateral pointed bars 10 can be guided and inserted into the side of the needle body 18, so that the multiple vertical spacer bars 8 can be distributed at intervals on the sides of the multiple needle bodies 18, thereby performing vertical spacing, positioning and shaping of the multiple needle bodies 18. When the linkage block 5 drives the support frame 12 to move upward, the support frame 12 drives the sensing strip 27 to move upward, and the sensing strip 27 can fit on the lower surface of the contact distance sensor 29. At the same time, the shaping block 3 supports the support sleeve block 28, and the support sleeve block 28 supports the contact distance sensor 29. The contact distance sensor 29 senses the fitting distance of the sensing strip 27. When the sensing strip 27 fits on the lower surface of the support sleeve block 28, the sensing distance of the contact distance sensor 29 is zero, and the reduction motor 14 is turned off through the controller 25.

[0042] Step 2: During the horizontal spacing positioning and shaping, the controller 25 starts the driving motor 31 at the same time, and the driving motor 31 drives the bidirectional screw 30 to rotate, and the bidirectional screw 30 rotates inside the sliding frame 26, and the bidirectional screw 30 drives the two threaded sleeves 32 to approach each other under the action of the thread transmission force. At the same time, the two threaded sleeves 32 respectively drive the two vertical shaping strips 33 to approach each other, and the lower vertical shaping strip 33 moves up along the outer wall of the multiple vertical spacing strips 8, thereby squeezing on the lower surface of the multiple needle bodies 18, and the upper vertical shaping strip 33 can move down and squeeze on the upper surface of the multiple needle bodies 18.

[0043] Step 3: When positioning and controlling the speed, when the upper vertical shaping strip 33 can move downward and squeeze on the upper surface of the plurality of needle bodies 18, the vertical shaping strip 33 drives the concave sleeve block 35 to move downward, the concave sleeve block 35 makes the support strip 38 move downward, the support strip 38 drives the pressure sensor 37 to move downward, and the pressure sensor 37 makes the guide column 36 move downward, and the guide column 36 drives the concave sleeve plate 39 to move downward. At the same time, the concave sleeve plate 39 drives the linkage shaft 41 to move downward, the linkage shaft 41 drives the speed roller 40 to move downward, and the concave sleeve plate 39 drives the bracket 43 to move downward, the bracket 43 makes the speed sensor 42 move downward, and the speed sensor 42 drives the linkage shaft 41 to move downward.

[0044] At the same time, the linkage shaft 41 drives the speed-averaging roller 40 to move downward and squeeze the upper surface of one of the needle bodies 18. In this way, the speed-averaging roller 40 drives the linkage shaft 41 upward after being squeezed, and the linkage shaft 41 drives the concave sleeve plate 39 to squeeze the guide column 36 on the pressure sensor 37, and the pressure sensor 37 senses the pressure value. When the pressure value sensed by the pressure sensor 37 is the same as the pressure value set by the concave sleeve block 35, it is known that the upper vertical shaping strip 33 is attached to the upper surface of the plurality of needle bodies 18 according to the specified pressure, and the lower vertical shaping strip 33 can be attached to the lower surface of the plurality of needle bodies 18 according to the specified pressure.

[0045] The controller 25 starts the electric cylinder 16 to drive the L-shaped support block 15 to move rightward, the L-shaped support block 15 drives the support frame 12 to move rightward, the support frame 12 drives the one-way screw 13 to move rightward, the one-way screw 13 makes the sleeve block 11 move rightward, the sleeve block 11 drives the linkage block 5 to move rightward, the linkage block 5 drives the linkage bar 6 to move rightward, the linkage bar 6 makes the multiple guide tip blocks 9 move rightward, and at the same time the vertical spacing bar 8 drives the lateral tip bar 10 to move rightward, the multiple vertical spacing bars 8 can move the side of the multiple needle bodies 18 horizontally to the right, and the multiple vertical spacing bars 8 can move and position the spacing gaps of the multiple needle bodies 18. At the same time, the linkage block 5 drives the sliding frame 26 to move rightward, the sliding frame 26 drives the bidirectional screw 30 to move rightward, the bidirectional screw 30 drives the two threaded sleeve blocks 32 to move rightward, and the two threaded sleeve blocks 32 respectively drive the two vertical shaping bars 33 to move rightward synchronously.

[0046] The upper vertical shaping strip 33 is shaped and positioned rightward along the upper surface of the plurality of needle bodies 18, while the lower vertical shaping strip 33 is shaped and positioned rightward along the lower surface of the plurality of needle bodies 18. The upper vertical shaping strip 33 drives the concave sleeve block 35 to move the guide column 36 rightward, the guide column 36 drives the concave sleeve plate 39 rightward, the concave sleeve plate 39 makes the linkage shaft 41 rightward, and the linkage shaft 41 can drive the uniform speed roller 40 to move rightward, and the uniform speed roller 40 and the upper surface of the needle body 18 are in frictional contact to realize the rotation operation. The uniform speed roller 40 drives the linkage shaft 41 to rotate, and the sleeve block 11 realizes speed sensing through the speed sensor 42, so that when the electric cylinder 16 drives the L-shaped support block 15 to move rightward, the speed sensed by the speed sensor 42 can be the same as the speed set by the controller 25, and the two vertical shaping strips 33 can perform horizontal spacing shaping and positioning on the plurality of vertical spacing strips 8 at the specified speed. In this way, the vertically bent parts of the plurality of needle bodies 18 can be shaped and positioned to be in a straight state. When the linkage bar 6 is moved rightward to reset to the starting position in step 1, the electric cylinder 16 can be closed by the controller 25 .

[0047] Step 4: When assembling the contact components of the wiring terminals, multiple needle bodies 18 can be positioned and shaped at vertical intervals inside the terminal 17, and multiple needle bodies 18 can also be positioned and shaped at horizontal intervals. Then the platform 1 supports the reinforcement block 20, and the reinforcement block 20 supports the extrusion cylinder 19. The extrusion cylinder 19 pushes the shaping block 3 to move left, and the multiple shaping grooves 4 inside the shaping block 3 can be positioned and inserted into multiple vertical spacing strips 8. At the same time, the platform 1 supports the socket plate 21, and the socket plate 21 supports the clamping electric cylinder 22. The clamping electric cylinder 22 pushes the clamping block 23 to move right, and the clamping block 23 drives the clamping end 24 to move right. The clamping end 24 is squeezed on the left end of the multiple needle bodies 18, so that the multiple needle bodies 18 can be extruded, assembled and locked with the terminal 17, and at the same time, the multiple needle bodies 18 are squeezed and fixed inside the terminal 17, so that the needle bodies 18 are positioned and assembled in the internal position of the terminal 17, completing the contact component assembly operation of the terminal 17 and the multiple needle bodies 18.
