Description

Technical Field

[0001] The present invention relates to the field of welding equipment, and specifically to a multi-station simultaneous welding equipment. Background Art

[0002] A welding equipment is a device used to join metals or thermoplastic materials together by heating, pressing, or a combination of both. Depending on the type of welding products, different types of welding equipment are used. When producing electronic products, electronic components need to be welded onto the product, the welding holes on the circuit board need to be aligned with the pins of the electronic components, and finally the pins are welded. For some processing factories, the pins of the electronic components need to be inserted onto the circuit board first, and then the pins are welded by an automatic welding equipment. When installing and welding with ordinary equipment, it is impossible to ensure that the pins are installed at the bottommost position. Failure to install at the bottommost position will cause poor welding during welding, seriously affecting the service life of the product. In response to the above problems, a patent application with the patent publication number CN116100111B provides a high-precision welding method for a camera module and a circuit board. It is positioned by a positioning jig for positioning the circuit board on a backing plate, and an installation and welding are performed by a tooling fixture for positioning and pressing the camera module arranged directly above the jig. However, when welding connection wires or some flexible wire harnesses, the connection wires will be deformed due to gravity or extrusion, resulting in the connection wires being unable to be accurately fixed to the middle position of the welding area, causing the connection wires not to be firmly combined with the electronic components, seriously affecting the service life of the product.

[0003] Therefore, a multi-station simultaneous welding equipment is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-station simultaneous welding equipment to solve the problem that the connection wires are deformed due to gravity or extrusion, resulting in the connection wires being unable to be accurately fixed to the middle position of the welding area, causing poor welding between the connection wires and the electronic components, and seriously affecting the service life of the product.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A multi-station simultaneous welding device, comprising a welding base, on which a plurality of wire conduits are fixedly installed. A connecting wire passing through the wire conduits is arranged inside the welding base. A clamping plate is installed on one side of the welding base. A welding box and a placement rack are arranged on one side of the welding base. A plurality of welding chambers equal in number to the wire conduits are arranged inside the welding box. A plurality of uniformly arranged arc-shaped grooves are formed on the side wall of the welding box close to the wire conduits. A plurality of uniformly arranged placement grooves are formed on the placement rack. The placement grooves correspond to the arc-shaped grooves and the positions of the plurality of wire conduits one by one. A long strip groove is formed at the bottom of the placement groove. A support plate is placed in the long strip groove. An arc-shaped notch matching the arc-shaped groove is formed on the support plate. A rotating rod is installed on the support plate. The rotating rod is rotatably connected to the inner walls of both sides of the long strip groove. A pushing component connecting the welding box and the placement rack is installed on the welding base. The clamping plate clamps the connecting wire and stretches the connecting wire to a specified position for continuous operation. When one side of the pushing component abuts against the clamping plate, the clamping plate drives the welding box and the placement rack to move through the pushing component, so that the welding box and the placement rack are separated from each other vertically and move close to the wire conduits. When one side of the pushing component disengages from the clamping plate, the pushing component drives the welding box and the placement rack to clamp the connecting wire on one side of the wire conduit and then return to the original position.

[0006] During use, multiple connecting wires are passed through the welding base, and the connecting wires enter the wire conduit. After the device is started, the driving device on one side drives the clamping plate to move, clamps the middle connecting wire, and drags it backward. At the same time, the wire stripping structure peels the part of the wire exposed from the wire conduit, so that the exposed part of the connecting wire after stripping can be welded and installed with electronic components. After the clamping plate pulls the connecting wire to move and finish stripping, it separates in the up and down directions. During the separation of the clamping plate, the driving and pushing assembly operates. The pushing assembly drives the welding box and the placement rack to move continuously closer to the wire conduit on one side. At the same time, during the movement, it drives the welding box and the placement rack to separate from each other, and after moving to a position close to the wire conduit, the welding box and the placement rack close together. The middle connecting wire is clamped through the arc-shaped groove and the placement groove. The arc-shaped notch opened on the support plate provided can be more easily matched with the arc-shaped groove, and the middle connecting wire can be clamped more precisely. Of course, because the welding position of the connecting wire and the electronic component is at the top of the electronic component, a gap will be generated between the connecting wire and the placement groove when the connecting wire is fixed. A long strip groove is opened at the bottom of the placement groove, and the support plate is rotatably connected to the long strip groove through a rotating rod. Through the swingable support frame, the placement groove can push the welded electronic component out of the placement groove to continue the welding process of the next electronic component. Through the mutual cooperation of the arc-shaped notch and the arc-shaped groove, the connecting wire will not be deflected before or during welding. After the clamping plate separates to the upper and lower sides, it needs to return to its original position, so that the clamping plate is far away from the pushing assembly. The pushing assembly drives the welding box and the placement rack to move backward, away from the wire conduit. After returning to the original position, the connecting wire and the electronic component in contact with each other are welded through the welding chamber. The middle connecting wire is clamped through the arc-shaped groove and the placement groove to prevent the connecting wire from being deflected before or during welding, resulting in a reduction in the welding quality of the product and ensuring the overall service life of the product after production.

[0007] Preferably, the pushing assembly includes a hydraulic cylinder, a limiting block, a ball, a compression spring, a fixed frame, a pushing block, a hydraulic rod, and a connecting pipe. A hydraulic cylinder is provided above the clamping plate. The movable end of the hydraulic cylinder is fixedly installed with a limiting block. A ball is rotatably connected to the limiting block. When the clamping plate rises, it abuts against the ball. A compression spring is abutted between the limiting block and the hydraulic cylinder. The compression spring is sleeved on the movable end of the hydraulic cylinder. A fixed frame is fixedly installed on the welding base. A limiting groove is opened in the fixed frame. A pushing block is slidably connected in the limiting groove. A hydraulic rod is fixedly installed on the fixed frame. A connecting pipe is connected between the hydraulic rod and the hydraulic cylinder. The movable end of the hydraulic rod is fixedly installed with the pushing block. A clutch is installed on the pushing block. The clutch connects the welding box and the placement rack on both sides.

[0008] When the pushing component is running, the clamping plate needs to be triggered. When the clamping plate is displaced directly below the hydraulic cylinder, it means that the clamping plate has pulled the connecting wire to the specified position. At this time, the clamping plate can move upward. During the upward movement of the clamping plate, it will press against the ball on the limiting block. Since both the limiting block and the ball are rigid structures, the continuously upward moving clamping plate will push the movable end of the hydraulic cylinder to contract through the limiting block and the ball, causing the liquid in the hydraulic cylinder to enter the other hydraulic rod through the connecting pipe, and making the movable end of the hydraulic rod extend forward. By the forward extension of the movable end of the hydraulic rod, the pushing block is pushed to move. The moving pushing block drives the welding box and the placement rack to move to one side through the clutch component. At the same time, while the clamping plate compresses the hydraulic cylinder through the limiting block, it will also squeeze the compression spring sleeved on the movable end of the hydraulic cylinder. After the clamping plate rises to the specified position, it needs to move away from the ball and return to its original position for the next clamping. Because the clamping plate is in contact with the ball when pushing the hydraulic cylinder to contract, the clamping plate can move smoothly during movement, and the generated friction is extremely small. Of course, because the compression spring on the movable end of the hydraulic cylinder is compressed, after the clamping plate moves away from below the hydraulic cylinder, the compressed compression spring pushes the movable end of the hydraulic cylinder back to its original position. Of course, during the process of the movable end of the hydraulic cylinder returning to its original position, it will extract the liquid in one side of the hydraulic rod through the connecting pipe, causing the movable end of one side of the hydraulic rod to contract. The contraction causes the clutch component to drive the welding box and the placement rack back to their original positions for welding. The power generated when the clamping plate returns is used to drive the clutch component to operate, causing the clutch component to drive the pushing block to move, and making the welding box and the placement rack move to one side for separation, clamping the connecting wire pulled out in the middle, avoiding the deviation of the connecting wire before or during welding, resulting in a reduction in the welding quality of the product, and ensuring the overall service life of the product after production.

[0009] Preferably, the clutch component includes a separation plate, large rollers, and a swinging block. Two mutually staggered separation plates are rotatably connected to one side of the pushing block. One ends of the two separation plates are respectively fixedly installed on the welding box and the placement rack. Two symmetrically arranged guiding grooves are formed on the fixed rack in the up and down direction. The other ends of the two separation plates are respectively rotatably connected to two large rollers. The two large rollers respectively roll in the upper and lower guiding grooves. A swinging block is rotatably connected in the guiding groove.

[0010] When the hydraulic rod pushes the pushing block to move closer to the wire conduit, since the upper and lower large rollers are respectively rotatably connected in the two guiding grooves, when the pushing block pulls the two separating plates connected thereto to move, the upper and lower large rollers will be driven to move together and roll in the guiding grooves, so that the large rollers drive the two separating plates rotatably connected to the pushing block to separate from each other in the upper and lower directions, causing the welding box and the placement rack connected to the separating plates to separate from each other in the upper and lower directions and continuously approach the wire conduit. After approaching the specified position, the guiding grooves cause the two large rollers to approach each other, pushing the welding box and the placement rack on the separating plates to approach each other in the middle, clamping the connecting wire near the wire conduit. After the hydraulic rod drives the pushing block away from the wire conduit, the middle connecting wire is straightened through the placement groove and the arc-shaped groove and the connecting wire is always located in the placement groove and the arc-shaped groove, so as to prevent the connecting wire from skewing before or during welding, resulting in a reduction in the welding quality of the product and ensuring the overall service life of the product after production.

[0011] Preferably, a through hole penetrating the left and right sides is formed in the support plate. A long strip plate is slidably connected in the through hole. The long strip plate is fixedly installed with a rotating rod. A plurality of short columns are fixedly installed in the through hole. A circular hole for the short columns to penetrate is formed in the long strip plate. A spring plate abutting against the long strip plate is arranged in the through hole. Locking grooves are formed on the side walls of both sides of the long strip groove. The center of the arc of the locking groove coincides with the center of the arc of the rotating rod. A small roller is rotatably connected in the locking groove. The small roller is rotatably connected to the support plate.

[0012] It should be noted that since the arc-shaped groove and the support plate cooperate with each other to clamp the middle connecting wire, when the connecting wire is pulled to one side at this time, it will slip due to the rotatable connection of the support plate and cannot be accurately fixed. Therefore, when the arc-shaped groove and the support plate cooperate with each other to clamp the middle connecting wire, the arc-shaped groove will continue to move downward to squeeze the lower support plate through the connecting wire. The squeezed support plate continues to move downward. Since a plurality of short columns are fixedly installed in the through hole and the long strip plate slides on it, when the support plate moves downward, the connected rotating rod remains in place. During the downward movement, the support plate drives the small roller to slide to the end of the locking groove, making the support plate unable to rotate. Of course, during the downward movement of the support plate, the spring plate inside the support plate will be compressed. When the arc-shaped groove and the support plate are separated from each other, the spring plate inside the support plate can return the support plate to its original position and can continue to move, further ensuring the cooperation between the arc-shaped notch and the arc-shaped groove so that the connecting wire will not skew before or during welding, improving the welding quality of the product, and ensuring the overall service life of the product after production.

[0013] Preferably, silicone pads are fixedly installed in both the arc-shaped notch and the arc-shaped groove. After the arc-shaped notch and the arc-shaped groove approach each other, they clamp the connecting wire in the middle. The silicone pads can clamp the connecting wire in the middle more smoothly. Since the connecting wire is made of a flexible material, while the arc-shaped notch and the arc-shaped groove are of rigid structures, the connecting wire will be worn when being clamped. However, the silicone pads made of a flexible material can avoid wear after contact, further improving the welding quality of the product and ensuring the overall service life of the product after production.

[0014] Preferably, a convex block is formed by separating between the two placement grooves on both sides. The two sides of the convex block close to the placement grooves are arc-shaped. A long groove is formed on the welding box, and the long groove is arranged in the middle of the two arc-shaped grooves. The side of the long groove expands towards the left and right sides. The welding box and the placement rack are closed to each other to further position the placement groove and the arc-shaped notch, avoiding displacement deviation after long-term use of the welding box and the placement rack, which may cause deviation in the welding of electronic components and ensuring the overall service life of the production equipment.

[0015] Preferably, the guiding groove is divided into a forward stroke and a return stroke. The return stroke is arranged in an inclined shape, and the lowest position of the inclination is arranged on the side away from the wire conduit. The return stroke is arranged in an inclined shape, so that the placement groove and the arc-shaped notch can gradually close during the return stroke, further ensuring that the connecting wire can be located in the middle position between the placement groove and the arc-shaped notch, ensuring the welding quality of the product and the overall service life of the product after production.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. During the process of the clamping plates separating from each other, the pushing component drives the welding box and the placement rack to move continuously closer to the wire conduit on one side. At the same time, during the movement, the welding box and the placement rack are driven to separate from each other, and after moving to a position close to the wire conduit, the welding box and the placement rack are closed to each other. The middle connecting wire is clamped by the arc-shaped groove and the placement groove, avoiding the skewing of the connecting wire before or during welding, ensuring the welding quality of the product, and ensuring the overall service life of the product after production.

[0017] 2. When the connecting wire is fixed, a gap will be generated between the connecting wire and the placement groove. The provided support plate can clamp the connecting wire more firmly. The swingable support frame enables the placement groove to push out the welded electronic components from the placement groove to continue the welding process of the next electronic component. The mutual cooperation of the arc-shaped notch and the arc-shaped groove avoids the skewing of the connecting wire before or during welding, ensuring the reduction of the welding quality of the product and ensuring the overall service life of the product after production.

[0018] 3. The downward movement of the arc-shaped groove squeezes the support plate through the connecting line. The squeezed support plate continues to move downward. During the downward movement, the support plate drives the small roller to slide to the end of the locking groove, preventing the support plate from rotating. This further ensures the coordinated use of the arc-shaped notch and the arc-shaped groove, preventing the connecting line from skewing during welding, improving the welding quality of the product, and ensuring the overall service life of the product after production.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Please refer to Figures 1 to 7 , the present invention provides a multi-station simultaneous welding device, and the technical solution is as follows: A multi-station simultaneous welding device, please refer to Figure 1 and Figure 3, including a welding base 1, on which a plurality of wire conduits 2 are fixedly installed. A connecting wire 3 passing through the wire conduits 2 is provided inside the welding base 1. A clamping plate 15 is installed on one side of the welding base 1. On one side of the welding base 1, there is a welding box 4 and a placement rack 5. Inside the welding box 4, there are a plurality of welding chambers equal in number to the wire conduits 2. On the side wall of the welding box 4 close to the wire conduits 2, a plurality of uniformly arranged arc-shaped grooves 18 are opened. On the placement rack 5, a plurality of uniformly arranged placement grooves 31 are opened. The positions of the placement grooves 31 and the arc-shaped grooves 18 and the plurality of wire conduits 2 correspond one by one. At the bottom of the placement groove 31, a long strip groove 23 is opened. Inside the long strip groove 23, a support plate 19 is placed. On the support plate 19, an arc-shaped notch 20 that cooperates with the arc-shaped groove 18 is opened. A rotating rod 27 is installed on the support plate 19. The rotating rod 27 is rotatably connected to the two inner side walls of the long strip groove 23. Silicone pads 32 are fixedly installed in both the arc-shaped notch 20 and the arc-shaped groove 18. After the arc-shaped notch 20 and the arc-shaped groove 18 approach each other, the connecting wire 3 in the middle is clamped.

[0022] Please refer to Figure 2 , Figure 6 and Figure 7 , above the clamping plate 15, there is a hydraulic cylinder 7. A limiting block 9 is fixedly installed at the movable end of the hydraulic cylinder 7. A ball 14 is rotatably connected to the limiting block 9. When the clamping plate 15 rises, it abuts against the ball 14. A compression spring 8 abuts between the limiting block 9 and the hydraulic cylinder 7. The compression spring 8 is sleeved on the movable end of the hydraulic cylinder 7. A fixing frame 6 is fixedly installed on the welding base 1. A limiting groove 11 is opened in the fixing frame 6. A pushing block 12 is slidably connected in the limiting groove 11. A hydraulic rod 13 is fixedly installed on the fixing frame 6. A connecting pipe is connected between the hydraulic rod 13 and the hydraulic cylinder 7. The movable end of the hydraulic rod 13 is fixedly installed with the pushing block 12. On one side of the pushing block 12, two mutually staggered separating plates 10 are rotatably connected. One ends of the two separating plates 10 are respectively fixedly installed on the welding box 4 and the placement rack 5. Two symmetrically arranged guiding grooves 16 are opened on the fixing frame 6. The other ends of the two separating plates 10 are respectively rotatably connected with two large rollers 17. The two large rollers 17 respectively roll in the upper and lower guiding grooves 16. A swinging block is rotatably connected in the guiding groove 16. The guiding groove 16 is divided into a forward stroke 161 and a return stroke 162. The return stroke 162 is arranged in an inclined shape, and the lowest position of the inclination is arranged on the side away from the wire conduit 2.

[0023] Please refer to Figure 4 and Figure 5, a through hole 24 penetrating both left and right sides is formed on the support plate 19. A long strip plate 26 is slidably connected in the through hole 24. The long strip plate 26 is fixedly installed with a rotating rod 27. A plurality of short columns 25 are fixedly installed in the through hole 24. Circular holes for the short columns 25 to penetrate are formed on the long strip plate 26. A spring plate 28 abutting against the long strip plate 26 is arranged in the through hole 24. Locking grooves 29 are formed on both side walls of the long strip groove 23. The arc centers of the locking grooves 29 coincide with the arc center of the rotating rod 27. Small rollers 30 are rotatably connected in the locking grooves 29. The small rollers 30 are rotatably connected to the support plate 19.

[0024] Please refer to Figure 1 and Figure 3 , a convex block 22 is formed by separating between the two placement grooves 31 on both sides. The two sides of the convex block 22 close to the placement grooves 31 are arc-shaped. A long groove 21 is formed on the welding box 4. The long groove 21 is arranged in the middle of the two arc grooves 18. The side of the long groove 21 expands towards the left and right sides.

[0025] Please refer to Figure 2 , Figure 6 and Figure 7 , wherein, when the clamping plate 15 is close to the welding base 1, it is moving forward, and when it is far from the welding base 1, it is moving backward. When in use, a plurality of connecting wires 3 are passed through the welding base 1, and the connecting wires 3 enter the wire conduit 2. After the device is started, the driving device on one side drives the clamping plate 15 to move towards the direction close to the connecting wires 3, clamps the middle connecting wires 3 and drags them backward. At the same time, the wire stripping structure installed on the clamping plate 15 will strip the connecting wires 3 for a specified length during the process of pulling the connecting wires 3 backward, so that the exposed part of the connecting wires 3 after being stripped can be welded and installed with electronic components. After the clamping plate 15 pulls the connecting wires 3 to move and the wire stripping is completed, the upper and lower clamping plates 15 move away from the connecting wires 3 respectively. During the process of the clamping plates 15 separating, when the clamping plate 15 is displaced directly below the hydraulic cylinder 7, it means that the clamping plate 15 has pulled the connecting wires 3 to the specified position. At this time, the clamping plate 15 can be separated towards the upper and lower sides. During the process of the upper clamping plate 15 moving upward, it will abut against the balls 14 on the limiting block 9. Since both the limiting block 9 and the balls 14 are rigid structure objects, the continuously upward moving clamping plate 15 will push the movable end of the hydraulic cylinder 7 upward through the limiting block 9 and the balls 14, the pressure in the hydraulic cylinder 7 increases, the liquid in the hydraulic cylinder 7 enters the movable end of the other hydraulic rod 13 through the connecting pipe and extends forward, and the pushing block 12 is pushed to move through the forward extension of the movable end of the hydraulic rod 13. At the same time, while the clamping plate 15 compresses the hydraulic oil in the hydraulic cylinder 7 through the limiting block 9, it will also squeeze the compression spring 8 sleeved on the movable end of the hydraulic cylinder 7.

[0026] Please refer to Figure 1 , Figure 2 and Figure 7, when the hydraulic rod 13 pushes the pushing block 12 to move closer to the wire conduit 2, since the upper and lower large rollers 17 are respectively connected by rolling in two guiding grooves 16, when the pushing block 12 pulls the two separating plates 10 connected thereto to move forward, the upper and lower large rollers 17 will be driven to move forward together and roll in the guiding grooves 16. At this time, the large rollers 17 are in the upwardly inclined stage of the guiding grooves 16, so that the large rollers 17 drive the two separating plates 10 rotatably connected to the pushing block 12 to separate from each other in the upper and lower directions, causing the welding box 4 and the placement rack 5 connected to the separating plates 10 to separate from each other in the upper and lower directions and continuously approach the wire conduit 2. After the welding box 4 and the placement rack 5 approach the specified position, when the large rollers 17 move to the downwardly inclined stage of the guiding grooves 16, the two large rollers 17 approach each other, pushing the welding box 4 and the placement rack 5 on the separating plates 10 to approach each other in the middle, and clamping the connecting wire 3 near the wire conduit 2.

[0027] Please refer to Figure 3 , Figure 4 and Figure 5 , by providing the support plate 19, the arc-shaped notch 20 formed thereon can be more easily engaged with the arc-shaped groove 18, and the connecting wire 3 in the middle can be clamped more precisely. By the swingable support plate 19, the placement groove 31 can push out the electronic components after welding from the placement groove 31 to continue the welding process of the next electronic component. Since the arc-shaped groove 18 and the support plate 19 are used in cooperation to clamp the connecting wire 3 in the middle, when the connecting wire 3 is pulled to one side at this time, it will slip due to the rotational connection of the support plate 19 and cannot be fixed precisely. Therefore, when the arc-shaped groove 18 and the support plate 19 cooperate to clamp the connecting wire 3 in the middle, the arc-shaped groove 18 will continue to move downward to squeeze the lower support plate 19 through the connecting wire 3. The squeezed support plate 19 continues to move downward. Since a plurality of short columns 25 are fixedly installed in the through holes 24, and the long strip plate 26 is slidably connected to the short columns 25, the support plate 19 is caused to move downward, while the connected rotating rod 27 remains in place. During the downward movement of the support plate 19, the support plate 19 drives the small roller 30 to slide to the end of the locking groove 29, making the support plate 19 unable to rotate. Of course, during the downward movement of the support plate 19, the spring plate 28 inside the support plate 19 will be compressed. When the arc-shaped groove 18 and the support plate 19 are separated from each other, the spring plate 28 inside the support plate 19 can reset the support plate 19 to its original position and can continue to move, further ensuring the cooperation between the arc-shaped notch 20 and the arc-shaped groove 18 so that the connecting wire 3 will not be deflected before or during welding.

[0028] Please refer to Figure 1 , Figure 2 and Figure 6, after the upper and lower clamping plates 15 are moved to the designated positions, they need to move away from the balls 14 and return to their original positions for the next clamping. Since the clamping plate 15 abuts against the balls 14 when pushing the hydraulic cylinder 7 to contract, the clamping plate 15 can move smoothly during displacement with extremely small friction. Of course, because the compression spring 8 on the movable end of the hydraulic cylinder 7 is compressed, when the clamping plate 15 moves away from the lower part of the hydraulic cylinder 7, the compressed compression spring 8 pushes the movable end of the hydraulic cylinder 7 back to its original position. Of course, during the process of the movable end of the hydraulic cylinder 7 returning to its original position, the liquid in one side of the hydraulic rod 13 will be extracted through the connecting pipe, causing the movable end of one side of the hydraulic rod 13 to contract.

[0029] Please refer to Figure 2 and Figure 7 , after the hydraulic rod 13 drives the pushing block 12 away from the wire conduit 2, the middle connecting wire 3 is straightened through the placement groove 31 and the arc groove 18 and the connecting wire 3 is always located within the placement groove 31 and the arc groove 18. The return stroke 162 is arranged in an inclined shape, so that the placement groove 31 and the arc-shaped notch 20 can gradually close during the return stroke 162, further ensuring that the connecting wire 3 can be located in the middle position between the placement groove 31 and the arc-shaped notch 20.

[0030] The above has described in detail a specific embodiment of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiment. For those skilled in the art, without departing from the principles and ideas of the present invention, various changes, modifications, substitutions, and variations made to these embodiments should still fall within the protection scope of the present invention.
