Description

Technical Field

[0001] The utility model belongs to the technical field of USB wire soldering machines, and provides a clamping wire fixture positioning device for a USB wire soldering machine. Background Art

[0002] After the two ends of a USB wire are peeled to expose the copper wire cores, USB connectors need to be soldered to the two ends of the USB wire respectively. Before soldering the USB connectors to the USB wire, the USB wire needs to be immersed in a soldering flux and then in tin successively. Therefore, a special USB wire soldering machine is required to firmly solder the USB connectors to the copper wire cores at the two ends of the USB wire.

[0003] The wire diameters of different models of USB wires are different, which makes the fixtures for clamping the USB wires different. The clamping forces and groove distances required for different fixtures to clamp the USB wires are different. If the wire diameter of the USB wire is too large, the outer skin of the USB wire is easily damaged by clamping. If the wire diameter of the USB wire is too small, gaps are easily generated and the USB wire is likely to become loose. Therefore, it is necessary to manually debug the installation position of the fixture in advance. During the debugging process, it is necessary to make samples of the product through experiments. If the first debugging fails, it is necessary to debug again. Multiple debuggings are required to achieve a satisfactory effect, which takes a relatively long time for the debugging device, makes it difficult for the positioning rod to accurately align with the fixture, affects the positioning effect, and is likely to delay the production task. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and solve the problem that the existing clamping wire fixture positioning device for a USB wire soldering machine is not convenient for clamping and fastening the USB wire.

[0005] The technical solution adopted by the utility model to solve its technical problem is: a clamping wire fixture positioning device for a USB wire soldering machine, including a support tray:

[0006] A pair of positioning rods are installed at the upper end of the support tray. A plurality of supports are arranged in front of the positioning rods. At the upper end of each support, a fixture two and a fixture one are respectively arranged on the left and right sides. Sliding pieces are installed at the lower ends of the fixture one and the fixture two and are slidably connected to the upper end of the corresponding support. Wire grooves are formed on the inner sides between two adjacent sliding pieces in the same support. Springs two are fixed between the ends of the sliding pieces far away from the wire grooves and the inner walls of the adjacent supports.

[0007] The two positioning rods are located above the corresponding two fixture ones below them. A slope two is formed on one side of the fixture one far away from the sliding piece and close to the corresponding fixture two. A slope one is formed on one side of the fixture one close to the sliding piece and far away from the corresponding fixture two. Springs one are installed between the slope one and the adjacent sliding pieces.

[0008] In a preferred technical solution of the present utility model, a support beam is slidably connected between the positioning rods. The rear end of the support beam is drivingly connected to a pneumatic motor II mounted on the upper end of the support bracket. A pair of limit pieces near the positioning rods are installed at the front end of the support beam. The positioning rods are in an "L" shape. A sensor I is installed at the front end of the positioning rod in front of the limit piece. A sensor II is installed at the front end of the limit piece.

[0009] In a preferred technical solution of the present utility model, the rear end of the support bracket is drivingly connected to a pneumatic motor I, and a support platform is installed at the lower end of the pneumatic motor I.

[0010] In a preferred technical solution of the present utility model, the socket is in a "U" shape and is arranged in a surrounding layout. A conveyor belt is installed between multiple sockets, and a pair of conveyor wheels are drivingly connected to the inner side of the conveyor belt.

[0011] In a preferred technical solution of the present utility model, a concave cavity II is formed in the middle of the end of the fixture II away from the sliding piece. A concave cavity I is formed in the middle of the end of the fixture I close to the corresponding sliding piece II. The concave cavity I communicates with the ramp II. An extension bar is detachably connected to the side of the fixture I close to the concave cavity II through a card.

[0012] In a preferred technical solution of the present utility model, a groove is formed in the side of the fixture I adjacent to the adjacent wire groove. A rotating shaft is rotatably connected in the middle between the fixture I and the adjacent sliding piece. The rotating shaft is located between the ramp I and the groove.

[0013] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0014] The pneumatic motor 1 drives the support bracket to move up and down. The two positioning rods approach or move away from above the fixture 1. The positioning rods contact or move away from the fixture 1. When the positioning rods contact the fixture 1, the wire groove can be opened. The spring 1 is compressed by the positioning rods and has a resilience force, so that the robotic arm on the assembly line can place the USB cable into the wire groove. After the positioning rods move away from the fixture 1, the USB cable is firmly clamped inside the wire groove by the resilience of the spring 1. The USB cable squeezes the sliding piece inside the wire groove, and the sliding piece slides to its left and right sides at the upper end of the same support base.

It can automatically adjust the gap between the two sliding pieces according to the wire diameter of the USB cable, and can also automatically adjust the distance between the fixture 1 and the fixture 2 located on the same support base. When the positioning rod moves upward and disengages from the fixture 1, the fixture 1 compresses the USB cable firmly in the wire groove by the resilience of the spring 1. The USB cable is automatically and firmly clamped in the wire groove. It can automatically adjust the clamping position according to the wire diameter of the USB cable and ensure firm clamping without manual adjustment in advance, making the placement position of the USB cable more accurate, enhancing the positioning effect of the positioning rod on the USB cable, saving time and improving efficiency.

Detailed Embodiment

[0021] Please refer to Figures 1-5 , the present utility model provides a technical solution: a wire clamping fixture positioning device for a USB wire soldering machine, including a support bracket 4. A pair of positioning rods 3 are installed at the upper end of the support bracket 4. A number of support seats 12 are arranged in front of the positioning rods 3. On the upper end of each support seat 12, a fixture two 14 and a fixture one 13 are respectively arranged on the left and right sides. Sliding pieces 23 which are slidably connected to the upper end of the corresponding support seat 12 are installed at the lower ends of both the fixture one 13 and the fixture two 14. A wire groove 24 is opened on the inner side between two adjacent sliding pieces 23 inside the same support seat 12. A second spring 21 is fixed between the end of the sliding piece 23 far away from the wire groove 24 and the inner wall of the adjacent support seat 12; The two positioning rods 3 are located above the corresponding two fixture ones 13 below them. A second slope 22 is opened at the end of the fixture one 13 far away from the sliding piece 23 and close to the corresponding fixture two 14. A first slope 19 is opened at the end of the fixture one 13 close to the sliding piece 23 and far away from the corresponding fixture two 14. A first spring 20 is installed between the first slope 19 and the adjacent sliding piece 23; A groove 25 is opened on one side of the fixture one 13 close to the adjacent wire groove 24. A rotating shaft 18 is rotatably connected in the middle between the fixture one 13 and the adjacent sliding piece 23. The rotating shaft 18 is located between the first slope 19 and the groove 25; The rear end of the support bracket 4 is drivingly connected to a first pneumatic motor 2. A support platform 1 is installed at the lower end of the first pneumatic motor 2. The first pneumatic motor 2 drives the support bracket 4 to move with the support platform 1 as a fulcrum. The first pneumatic motor 2 drives the support bracket 4 to move up and down. The positioning rods 3 move up and down as the support bracket 4 moves up and down. The two positioning rods 3 move closer to or away from above the fixture one 13, the positioning rods 3 contact the fixture one 13 or move away from the fixture one 13. The first pneumatic motor 2 realizes the effect of the positioning rods 3 moving back and forth up and down;

[0022] Let the pneumatic motor - 2 lower the support bracket 4. The support bracket 4 drives the two positioning rods 3 to move downward. The two positioning rods 3 respectively move downward and approach the adjacent fixture - 13. The fixture - 13 is squeezed downward by the adjacent positioning rod 3 and rotates along the adjacent rotating shaft 18. The rotating shaft 18 provides a rotating force point for the adjacent fixture - 13. The fixture - 13 tilts in the direction of approaching the slope - 19 along the adjacent rotating shaft 18 and closely adheres to the surface of the corresponding sliding piece 23. When the fixture - 13 tilts, it flips. The concave cavity - 15 and the extension strip 16 tilt upward and away from the wire groove 24 as the fixture - 13 flips and tilts. The first spring 20 is squeezed by the adjacent fixture - 13 flipping and tilting. The first spring 20 is compressed by the adjacent fixture - 13, thus revealing the wire groove 24. Therefore, when the positioning rod 3 contacts the fixture - 13, the wire groove 24 can be opened, facilitating the robotic arm on the assembly line to grab and align the USB cable with the wire groove 24. In the middle of one end of the fixture - 13 close to the corresponding sliding piece 23, there is a concave cavity - 15, and the concave cavity - 15 communicates with the slope - 22. One side of the fixture - 13 close to the concave cavity - 17 is detachably connected with an extension strip 16. In the middle of one end of the fixture - 2 14 away from the sliding piece 23, there is a concave cavity - 17. The concave cavity - 15 and the concave cavity - 17 provide an activity area for the robotic arm on the assembly line to grab the USB cable. The robotic arm on the assembly line places the USB cable into the wire groove 24;

[0023] A support beam 6 is slidably connected between the positioning rods 3. At the front end of the support beam 6, there are a pair of limit pieces 7 near the positioning rods 3. At the rear end of the support beam 6, it is drivingly connected to a pneumatic motor - 2 5 installed on the upper end of the support bracket 4. The pneumatic motor - 2 5 drives the support beam 6 to move back and forth along the surface between the two positioning rods 3. The limit pieces 7 move back and forth as the support beam 6 moves back and forth, enabling the support beam 6 to adjust the placement position of the limit pieces 7 beside the positioning rods 3, making the head and tail ends of the USB cable closely adhere to the surface of the adjacent limit pieces 7. The limit pieces 7 prevent the USB cable from exceeding the placement area, and the limit pieces 7 play a role in limiting the USB cable. The positioning rods 3 are in an "L" shape. At the front end of the positioning rods 3, there is a sensor - 1 8 in front of the limit pieces 7. At the front end of the limit pieces 7, there is a sensor - 2 9. The sensor - 1 8 and the sensor - 2 9 emit infrared rays, enabling the robotic arm to sense whether the placement position of the USB cable is correct, so as to prompt the robotic arm on the assembly line to place the USB cable in the correct position;

[0024] After the positioning rod 3 moves upward and disengages from the first fixture 13, the first spring 20 is compressed by the positioning rod 3 and has a resilience force. Relying on the resilience of the first spring 20 on the surface of the first inclined slope 19, the first spring 20 raises the first fixture 13 on the side of the first inclined slope 19. The fixture on the side of the first inclined slope 19 flips along the corresponding rotating shaft 18 and tilts away from the sliding piece 23. The first fixture 13 near the first cavity 15 and the extension strip 16 resumes its original state and moves closer to the wire groove 24. The USB cable gradually embeds into the groove 25 inside the wire groove 24, and relying on the resilience of the first spring 20, the first fixture 13 presses the USB cable firmly into the wire groove 24;

[0025] The support 12 is in a "U" shape and is arranged in a surrounding layout. A transmission belt 10 is installed between multiple supports 12. A pair of transmission wheels 11 are drivingly connected to the inner side of the transmission belt 10. Relying on the transmission wheels 11 to drive the transmission belt 10 to move, all the supports 12 achieve the effect of transmission as the transmission belt 10 moves. The supports 12 transfer the first fixture 13 and the second fixture 14 along the transmission belt 10. The first fixture 13 and the second fixture 14 inside the same support 12 take turns passing between the two positioning rods 3;

[0026] The USB cable squeezes the sliding piece 23 inside the wire groove 24. The sliding piece 23 slides to its left and right sides at the upper end of the same support 12. The two sliding pieces 23 at the upper end of the same support 12 gradually move away from each other. The sliding piece 23 compresses the second spring 21. After the second spring 21 is compressed by the sliding piece 23, it has a resilience force. The second spring 21 rebounds and moves the corresponding sliding piece 23 in the reverse direction of the original moving direction. The second spring 21 makes the two sliding pieces 23 at the upper end of the same support 12 gradually move closer to each other. The two sliding pieces 23 at the upper end of the same support 12 clamp the USB cable firmly in the wire groove 24. It can automatically adjust the gap between the two sliding pieces 23 according to the wire diameter of the USB cable, and can automatically adjust the distance between the first fixture 13 and the second fixture 14 on the same support 12, so that the first fixture 13 clamps the USB cable firmly inside the wire groove 24. The USB cable is automatically and firmly clamped in the wire groove 24. It can automatically adjust the clamping position according to the wire diameter of the USB cable and can ensure firm clamping without manual adjustment in advance, making the placement position of the USB cable more accurate, enhancing the positioning effect of the positioning rod 3 on the USB cable, saving time, and improving efficiency.

[0027] Working principle:

[0028] (1) Let the pneumatic motor 2 lower the support 4. The support 4 drives the two positioning rods 3 to move downward. The two positioning rods 3 respectively move downward and approach the adjacent fixture 13. The fixture 13 is squeezed downward by the adjacent positioning rod 3 and rotates along the adjacent rotating shaft 18. The rotating shaft 18 provides a rotating force point for the adjacent fixture 13. The fixture 13 tilts in the direction of approaching the slope 19 along the adjacent rotating shaft 18 and closely adheres to the surface of the corresponding sliding piece 23. When the fixture 13 tilts, it flips. The concave cavity 15 and the extension strip 16 tilt upward and away from the wire groove 24 as the fixture 13 flips and tilts. The first spring 20 is squeezed by the adjacent fixture 13 when it flips and tilts. The first spring 20 is compressed by the adjacent fixture 13, thus revealing the wire groove 24. Therefore, when the positioning rod 3 contacts the fixture 13, the wire groove 24 can be opened, facilitating the robotic arm on the assembly line to grab and align the USB cable with the wire groove 24;

[0029] (2) After the positioning rod 3 moves upward and disengages from the fixture 13, the first spring 20 is compressed by the positioning rod 3 and has a resilience force. Relying on the resilience of the first spring 20 on the surface of the slope 19, the first spring 20 raises the side of the fixture 13 located on the slope 19. The side of the fixture located on the slope 19 flips along the corresponding rotating shaft 18 and tilts away from the sliding piece 23. The side of the fixture 13 near the concave cavity 15 and the extension strip 16 restores and approaches the wire groove 24. The USB cable gradually embeds into the groove 25 inside the wire groove 24. Relying on the resilience of the first spring 20, the fixture 13 compacts the USB cable in the wire groove 24;

[0030] (3) The USB cable squeezes the sliding piece 23 inside the wire groove 24. The sliding piece 23 slides to its left and right sides at the upper end of the same support 12. The two sliding pieces 23 at the upper end of the same support 12 gradually move away from each other. The sliding piece 23 compresses the second spring 21. After the second spring 21 is compressed by the sliding piece 23, it has a resilience force. The second spring 21 rebounds and moves the corresponding sliding piece 23 in the reverse direction of the original moving direction. The second spring 21 makes the two sliding pieces 23 at the upper end of the same support 12 gradually approach each other. The two sliding pieces 23 at the upper end of the same support 12 clamp the USB cable in the wire groove 24. It can automatically adjust the gap between the two sliding pieces 23 according to the wire diameter of the USB cable, and can automatically adjust the distance between the fixture 13 and the fixture 2 at the upper end of the same support 12, so that the fixture 13 firmly clamps the USB cable inside the wire groove 24. The USB cable is automatically and firmly clamped in the wire groove 24. It can automatically adjust the clamping position according to the wire diameter of the USB cable and ensure firm clamping without manual adjustment in advance, making the placement position of the USB cable more accurate, enhancing the positioning effect of the positioning rod 3 on the USB cable, saving time and improving efficiency.
