Description

Technical Field

[0001] This application relates to the technical field of terminal block processing, and in particular to a high-efficiency terminal block press-fitting machine. Background Technology

[0002] Terminal blocks are electrical components used in electrical equipment to connect wires to equipment or circuit boards.

[0003] The main components of terminal block assembly are the base and the insert. Currently, the installation of the insert and the base mostly relies on manual installation by hand or with the assistance of tweezers. This assembly method is time-consuming and labor-intensive, resulting in low processing efficiency. Summary of the Invention

[0004] To improve processing efficiency, this application provides a high-efficiency terminal block press-fitting machine.

[0005] The high-efficiency terminal block press-fitting machine provided in this application adopts the following technical solution:

[0006] A high-efficiency terminal block press machine, comprising:

[0007] The conveying section includes a first conveyor and a second conveyor. The first conveyor is used to convey the base, and the second conveyor is used to convey the insert.

[0008] Press-fitting section, used to insert the insert into the base;

[0009] The guide section is used to transport the insert to the pressing section.

[0010] Using the above technical solution, the inserts transported by the second conveyor fall into the guide section, and then enter the pressing section, whereby the pressing section inserts the inserts into the base conveyed by the first conveyor. In this way, a mechanical structure replaces manual operation, and the mechanical structure's operating efficiency is higher than that of manual labor, thereby improving processing efficiency.

[0011] Optionally, the pressing section includes a pressing unit, a driving unit, and a moving unit;

[0012] The pressing unit includes a fixed base and a clamping plate. The fixed base is frame-shaped, and there are two clamping plates. The two clamping plates are arranged opposite to each other and are slidably connected in the fixed base. A reset plate is fixedly connected to the clamping plate, and a reset spring is fixed between the reset plate and the fixed base.

[0013] The drive unit is used to squeeze the clamping plate to hold the insert;

[0014] The moving unit is used to move the pressing unit to insert the insert into the base.

[0015] Using the above technical solution, after the insert comes out of the guide section, it falls between the two clamping plates. The two clamping plates are squeezed and hold the insert in place. The moving unit moves the fixed seat with the clamped insert towards the first conveyor, thereby inserting the insert into the base. After the moving unit resets the fixed seat, it continues to repeat the above movement process, thus realizing continuous operation.

[0016] Optionally, the drive unit includes a drive base, a drive motor, a drive gear, and a drive rack. A linkage plate is fixed between the drive base and the fixed base. A cavity is opened in the drive base. The drive gear is disposed in the cavity. The drive motor is used to drive the drive gear to rotate. The drive rack is slidably connected to the drive base. The drive rack passes through the cavity and meshes with the drive gear. A first transmission rod is fixed at one end of the drive rack near the pressing part. The first transmission rod is used to press the clamping plate.

[0017] Using the above technical solution, the drive motor starts and drives the drive rack to slide within the drive seat via the drive gear, thereby driving the rack to move the first transmission rod closer to or further away from the clamping plate. When the first transmission rod approaches the clamping plate, it presses against the clamping plate, thus clamping the insert piece between the two clamping plates; when the first transmission rod moves away from the clamping plate, the clamping plate returns to its original position. Through the above movement process, the drive unit achieves the effect of controlling the position of the clamping plate.

[0018] Optionally, the moving unit includes a moving lead screw, a base, a rotating motor, and a bevel gear set. The moving lead screw is slidably connected inside the base, and a moving screw sleeve is threaded onto the moving lead screw. The moving screw sleeve is rotatably connected to the base, and the moving screw sleeve is driven to rotate through the bevel gear set.

[0019] Using the above technical solution, the rotating motor causes the moving screw to slide inside the base through the bevel gear set, thereby controlling the length of the moving screw extending out of the base. This achieves the effect of controlling the height of the fixed seat, and further achieves the effect of inserting the insert into the base and resetting the fixed seat after insertion.

[0020] Optionally, the base has a through hole for the movable lead screw to slide, a limiting block is fixed in the through hole, and a limiting groove is provided on the outer wall of the movable lead screw to be adapted to slide with the limiting block.

[0021] Using the above technical solution, during the movement of the movable lead screw, the limiting block slides in the limiting groove, thereby making it difficult for the movable lead screw to rotate with the movable screw sleeve, thus achieving the effect of guiding and limiting the movable lead screw.

[0022] Optionally, a support frame is mounted on one end of the second conveyor. The support frame is gantry-shaped and a stop assembly is provided on the support frame. The stop assembly includes a moving rod and a baffle. The moving rod is slidably connected to the top of the support frame. The baffle is fixed to the end of the moving rod near the second conveyor. A telescopic spring is fixed between the baffle and the support frame.

[0023] The drive unit is also used to compress the moving rod, and a sliding component is fixed at the end of the moving rod away from the baffle.

[0024] Using the above technical solution, the baffle is used to prevent the insert from falling off the second conveyor, thereby buying time for the pressing part to reset. After the pressing part is reset, the baffle no longer obstructs the movement of the insert; the sliding assembly reserves a height difference for the pressing part to move up and down.

[0025] Optionally, the sliding assembly includes a slider and a return plate, one end of the moving rod is inserted into the slider and the two are slidably adapted to each other, the return plate is fixedly connected to the moving rod, and a return spring is fixed between the return plate and the slider.

[0026] Using the above technical solution, the slider is squeezed. At this time, the return spring does not deform, the extension spring deforms, and the moving rod slides on the support frame, so that the baffle hinders the movement of the insert. When the pressing part moves close to the first conveyor, the slider continues to be squeezed. At this time, the return spring deforms, the extension spring reaches its maximum deformation, so the slider slides along the moving rod, thus reserving a height difference for the movement of the pressing part.

[0027] Optionally, the guide portion includes an upper limit unit and a lower limit unit, which are arranged opposite to each other, with a gap between the upper limit unit and the lower limit unit for the insert to pass through.

[0028] Using the above technical solution, the insert falls from the second conveyor into the gap between the upper limit unit and the lower limit unit, slides within the gap until it slides into the pressing section.

[0029] Optionally, the pressing part further includes a receiving unit, which is mounted on a fixed base. The receiving unit includes a receiving block and an electric cylinder, which is used to drive the receiving block to extend into the middle of the two clamping plates or retract to its original position.

[0030] Using the above technical solution, the insert slides out from the guide and falls onto the receiving block. When the clamping plate clamps the insert, the electric cylinder starts to retract the receiving block. Thus, the receiving block will not obstruct the movement of the insert when it is inserted into the base.

[0031] Optionally, pads are fixed to the opposing surfaces of the two clamping plates.

[0032] By adopting the above technical solution, the insert is protected by a flexible pad, reducing damage to the insert during clamping.

[0033] In summary, this application includes the following beneficial technical effects:

[0034] The insert conveyed by the second conveyor falls into the gap between the upper limit unit and the limiting unit. The insert, sliding out through the guide section, falls onto the receiving block. The clamping plate, under pressure, holds the insert, and the fixed base moves to insert the clamped insert into the base conveyed by the first conveyor. In this way, a mechanical structure replaces manual operation, and the mechanical structure's operating efficiency is higher than manual labor, thus improving processing efficiency.

Detailed Implementation

[0042] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0043] This application discloses a high-efficiency terminal block press-fitting machine.

[0044] refer to Figure 1 A high-efficiency terminal block pressing machine includes a conveying section 1, a guiding section 5, and a pressing section. The conveying section 1 includes a first conveyor 11 and a second conveyor 12. The first conveyor 11 is used to transport a base 111, and the second conveyor 12 is used to transport a insert 121. The pressing section includes a pressing unit 2, a driving unit 3, and a moving unit 4.

[0045] Insert 121 falls from the second conveyor 12 into the guide section 5. Insert 121 falls through the guide section 5 and is clamped by the drive unit 3 and the pressing unit 2. Then, the insert 121 is inserted into the base 111 on the first conveyor 11 by the moving unit 4 and the pressing unit 2.

[0046] refer to Figure 1 A support frame 6 is mounted on one end of the second conveyor 12. The support frame 6 is shaped like a gate. The bottom of the support frame 6 is fixed to the body of the second conveyor 12. A stop assembly 7 is provided on the support frame 6.

[0047] refer to Figure 2The gear shift assembly 7 includes a moving rod 71 and a baffle 72. The moving rod 71 is slidably connected to the top of the support frame 6 in the vertical direction. The baffle 72 is fixed to the bottom end of the moving rod 71. A telescopic spring 721 is fixed between the baffle 72 and the support frame 6. The telescopic spring 721 is sleeved on the moving rod 71. A sliding assembly 8 is provided at the top end of the moving rod 71.

[0048] refer to Figure 2 The sliding assembly 8 includes a slider 81 and a return plate 82. The top end of the moving rod 71 is inserted into the slider 81 but does not penetrate through the slider 81. The part of the moving rod 71 inserted into the slider 81 is slidably adapted to the slider 81. The return plate 82 is sleeved on the top of the moving rod 71 and the two are fixedly connected. A return spring 821 is fixed between the return plate 82 and the slider 81. The return spring 821 is sleeved on the moving rod 71, and the force that the return spring 821 needs to overcome when it deforms is greater than the force that the extension spring 721 needs to overcome when it deforms.

[0049] refer to Figure 2 The guide part 5 is located on one side of the support frame 6. The guide part 5 includes an upper limit unit 51 and a lower limit unit 52. The upper limit unit 51 is fixedly connected to the support frame 6 by a hanging rod 61. The lower limit unit 52 is fixedly connected to the body of the second conveyor 12 by a support rod 122. The upper limit unit 51 and the lower limit unit 52 are arranged opposite to each other, and a gap is left between the upper limit unit 51 and the lower limit unit 52 for the insert 121 to pass through.

[0050] After the insert 121 falls from the second conveyor 12, it enters the gap between the upper limit unit 51 and the lower limit unit 52. Then the insert 121 slides along the gap until it slides out of the guide part 5, and then the insert 121 falls onto the receiving unit 9.

[0051] After the insert 121 at the end of the second conveyor 12 falls off, during the process of the drive unit 3 starting and clamping the insert 121 through the pressing unit 2, the slider 81 is squeezed. At this time, the return spring 821 does not deform, but the extension spring 721 deforms. As a result, the slider 81 drives the moving rod 71 to slide downward, so that the lower surface of the baffle 72 contacts the surface of the conveyor belt of the second conveyor 12, thereby preventing the insert 121 from continuing to move forward. When the moving unit 4 drives the insert 121 to insert downward into the base 111, the slider 81 continues to be squeezed. At this time, the return spring 821 deforms, and the extension spring 721 reaches its maximum deformation. As a result, the slider 81 slides downward along the moving rod 71.

[0052] When the moving unit 4 drives the pressing unit 2 to reset upward, the return spring 821 releases its elastic force, thereby driving the slider 81 to reset; when the driving unit 3 starts to restore the pressing unit 2 to its initial state, the telescopic spring 721 releases its elastic force to drive the baffle 72 to reset, and the insert 121 is driven by the second conveyor 12 to continue moving forward.

[0053] refer to Figure 3 and Figure 4 The pressing unit 2 includes a fixed base 21, which is frame-shaped. A clearance groove 211 is provided on the lower surface of the fixed base 21. A receiving unit 9 is provided in the clearance groove 211. The receiving unit 9 includes a receiving block 91 and an electric cylinder 92. The electric cylinder 92 is fixedly installed in the clearance groove 211 of the fixed base 21. The receiving block 91 is fixedly connected to the piston rod end of the electric cylinder 92.

[0054] refer to Figure 3 The pressing unit 2 also includes a clamping plate 22. There are two clamping plates 22, which are arranged opposite to each other. Both clamping plates 22 are slidably connected in the fixed seat 21. The opposing surfaces of the two clamping plates 22 are fixed with pads 222, which are made of rubber.

[0055] refer to Figure 3 and Figure 4 Both sides of the clamping plate 22 are fixedly connected to a reset plate 221. A telescopic rod is fixedly connected between the reset plate 221 and the fixed seat 21. The telescopic rod has a multi-stage telescopic structure, including an inner rod and an outer rod. A reset spring 2211 is sleeved on the telescopic rod. The two ends of the reset spring 2211 are fixedly connected to the reset plate 221 and the fixed seat 21, respectively.

[0056] refer to Figure 3 and Figure 5 The drive unit 3 includes a drive base 31, a drive motor 32, a drive gear 33, and a drive rack 34. A linkage plate 311 is fixed between the drive base 31 and the fixed base 21. A cavity 312 is opened inside the drive base 31. The drive motor 32 is fixedly installed on the drive base 31. The output shaft end of the drive motor 32 is fixedly connected to the drive gear 33. The drive rack 34 meshes with the drive gear 33. The drive rack 34 passes through the drive base 31 and through the cavity 312 in a vertical direction. The drive rack 34 is slidably adapted to the drive base 31.

[0057] refer to Figure 2 and Figure 3 The top end of the drive rack 34 is fixedly connected to a second transmission rod 342 for pressing the slider 81, and the bottom end of the drive rack 34 is fixedly connected to a first transmission rod 341 for pressing the clamping plate 22.

[0058] After the insert 121 falls onto the receiving block 91, the drive motor 32 starts and drives the drive gear 33 to rotate. The drive gear 33 drives the drive rack 34 to move downward. At this time, the drive rack 34 drives the first transmission rod 341 to squeeze the clamping plate 22, so that the two clamping plates 22 clamp the insert 121. At the same time, the drive rack 34 drives the second transmission rod 342 to squeeze the slider 81, so that the baffle 72 falls down to prevent the insert 121 from moving forward. During the process of the moving unit 4 driving the insert 121 to insert downward into the base 111, the electric cylinder 92 starts to retract the receiving block 91. At the same time, the drive rack 34 continues to squeeze the slider 81 through the second transmission rod 342.

[0059] When the moving unit 4 drives the pressing unit 2 to reset upward, the driving rack 34 drives the second transmission rod 342 away from the slider 81, at which time the slider 81 is reset; when the driving unit 3 starts to restore the pressing unit 2 to its initial state, the driving rack 34 drives the second transmission rod 342 to continue to move away from the slider 81, at which time the baffle 72 rises.

[0060] refer to Figure 3 and Figure 6 There are two moving units 4, which are respectively located on both sides of the first conveyor 11. Each moving unit 4 includes a moving screw 41 and a base 42. The moving screw 41 is slidably connected to the base 42. The base 42 has a through hole 421 for the moving screw 41 to slide. A limiting block 422 is fixed in the through hole 421 of the base 42. The outer wall of the moving screw 41 has a limiting groove 411 that is slidably adapted to the limiting block 422. A moving screw sleeve 412 is threadedly connected to the moving screw 41. The moving screw sleeve 412 is rotatably connected to the base 42.

[0061] refer to Figure 6 The moving unit 4 also includes a rotating motor 43 and a bevel gear set 44. The rotating motor 43 is mounted on the base 42. The bevel gear set 44 includes a driving bevel gear 441 and a driven bevel gear 442. The driving bevel gear 441 is fixedly connected to the output shaft of the rotating motor 43. The driven bevel gear 442 meshes with the driving bevel gear 441. The driven bevel gear 442 is sleeved on the moving screw sleeve 412 and the two are fixedly connected.

[0062] The rotating motor 43 starts and drives the active bevel gear 441 to rotate. The active bevel gear 441 drives the driven bevel gear 442 to rotate. The driven bevel gear 442 drives the moving screw sleeve 412 to rotate. Thus, the moving screw sleeve 412 drives the moving lead screw 41 to move up or down. In turn, the moving lead screw 41 drives the fixed seat 21 to move up or down. During the movement of the moving lead screw 41, the limiting block 422 slides in the limiting groove 411.

[0063] The implementation principle of a high-efficiency terminal press-fitting machine according to an embodiment of this application is as follows: the insert 121 falls from the second conveyor 12 into the guide section 5, and then falls onto the receiving block 91. After the two clamping plates 22 clamp the insert 121 that has fallen onto the receiving block 91, the electric cylinder 92 is activated to retract the receiving block 91. Then, the rotating motor 43 is activated to drive the moving screw sleeve 412 to rotate through the bevel gear set 44. Thus, the moving screw sleeve inserts the insert 121 clamped by the clamping plates 22 into the base 111 through the fixed seat 21. Through the above movement process, the effect of improving processing efficiency is achieved.

[0064] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
