Description

Technical Field

[0001] The present invention belongs to the technical field of integrated circuit manufacturing, and specifically relates to a PCB board welding machine. Background Art

[0002] An integrated circuit is a microelectronic device. By using a specific process, components such as transistors, resistors, and capacitors and wirings are integrated on a semiconductor wafer or dielectric substrate. After encapsulation, it forms an integral body with specific circuit functions, having the characteristics of small size, light weight, low power consumption, high reliability, etc.; A PCB is a support for electronic components and a carrier for electrical connections, which is made by electronic printing technology. It consists of circuits, dielectric layers, holes, solder mask inks, etc., having advantages such as high reliability, designability, maintainability, etc.; The PCB provides physical support and electrical connection for the integrated circuit. The integrated circuit is fixed on the PCB by welding and becomes a part of the circuit board.

[0003] The automatic welding equipment for PCB boards is mainly used for automated production. The automatic welding equipment can achieve continuous and efficient welding operations, without the need for frequent manual intervention and adjustment. It can weld multiple PCB boards per minute, thus greatly improving the production capacity.

[0004] A patent with the publication number CN117399860B discloses a PCB board welding robot. By controlling the reciprocating fixed-distance telescopic movement of the electric telescopic rod to drive the one-way rotation of the ratchet wheel, the conveyor can perform fixed-distance movement and transportation. At the same time, in cooperation with the operation of the feeding mechanism, multiple stacked circuit boards can be automatically placed on multiple installation platforms in sequence. At the same time, in cooperation with the operation of the positioning mechanism and the triggering mechanism, the circuit boards on the installation platforms can be stably clamped to ensure the stability during welding. At the same time, the welded circuit boards on the installation platforms can also be automatically loosened and removed, so that during the overall use, it is not necessary for the staff to frequently manually place the PCB boards into the fixture or take them out of the fixture, ensuring the overall welding efficiency, and at the same time avoiding the high-temperature solder joints after welding from causing harm to the hands of the staff. The whole can perform automated processing.

[0005] In the above-mentioned prior art, when it is necessary to weld a wire to a PCB board, it is necessary for a person to wear gloves to pick up the wire, align it with the welding point on the PCB board, and then drive the automatic welding head to approach the contact part between the wire and the welding point for welding. Since the wire needs to be manually picked up during the welding process to make the wire contact the welding point on the PCB board, during the welding process, it is necessary to keep the wire stationary. During the welding process, the hand is relatively close to the welding head. Since the temperature of the welding head of the welding machine is relatively high, the temperature of the welding machine table will become higher after a long time of welding, and there are certain safety hazards during the welding process.

[0006] Therefore, the present invention provides a PCB board welding machine. Summary of the Invention

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0023] Example 1: As Figures 1-3 shown, a PCB board welding machine according to an embodiment of the present invention includes a workbench 1, a support platform 11 is fixedly connected to the upper end of the workbench 1, a welding head 2 is slidably installed on the upper end of the support platform 11, the welding head 2 is connected to a welding machine body through a power cord and an air pipe, a feeding component is arranged on one side of the support platform 11, the feeding component includes two first rectangular strips 3 slidably arranged on the upper end of the workbench 1, and several groups of clamping components are arranged between the two first rectangular strips 3. The clamping components include two L-shaped clamping strips 31, and third round holes 315 are arranged in the middle of the L-shaped clamping strips 31. Several L-shaped clamping strips 31 can slide outside the third cylindrical strip 34 through the third round holes 315, and the third cylindrical strip 34 is arranged between the two first rectangular strips 3.

[0024] Specifically, the welding machine is a hot press welding machine. The welding head 2 is matched with the hot press welding machine. The welding head 2 is of a telescopic structure. When welding a PCB board, several wires need to be welded to the PCB board. The traditional welding method generally manually places the wires at the welding points on the upper end of the PCB board and then uses a welding device for welding. During the welding process, the welding head of the welding machine will generate a relatively high temperature, and manually placing the wires has certain safety hazards. When using the present invention, the PCB board is placed on the upper end of the support table 11 chamber. Then, several L-shaped clamping strips 31 are driven to clamp the wires. Subsequently, the first rectangular strip 3 is driven to drive the wires clamped in the middle of several L-shaped clamping strips 31 to move towards the side close to the PCB board until the wires are moved to the welding points. Then, the welding head 2 is driven to move to the welding points for welding. By driving the L-shaped clamping strips 31 to clamp the wires and then moving them to the welding points of the PCB board for welding, it enables the staff not to approach the welding head of the welding machine during the welding process, preventing burns from high temperatures.

[0025] As Figures 3-4 shown, the clamping assembly further includes a first rectangular block 322 slidably arranged on the upper ends of two L-shaped clamping strips 31. An L-shaped strip 321 is slidably arranged inside one side of the first rectangular block 322. A first triangular block 32 is fixedly connected to one side of the L-shaped strip 321. The first triangular block 32 is located between the two L-shaped clamping strips 31. A first cylindrical bar 323 is fixedly connected to one side of the L-shaped strip 321. The first cylindrical bar 323 slidably penetrates through one side of the first rectangular block 322. A second rectangular block 324 is fixedly connected to one side of the first cylindrical bar 323. Circular ring grooves 311 are respectively arranged on the opposite sides of the two L-shaped clamping strips 31. A cylinder 313 is slidably arranged in the two circular ring grooves 311. A second spring 314 is sleeved on the outer side of the cylinder 313. Second circular holes 312 are arranged in the middle of the circular ring grooves 311. A second cylindrical bar 33 slidably moves in the middle of several second circular holes 312. The two ends of the second cylindrical bar 33 and a third cylindrical bar 34 are fixedly connected through waist-shaped blocks 341 respectively. The waist-shaped blocks 341 are respectively fixedly connected to the first rectangular strip 3.

[0026] Specifically, by driving the second rectangular block 324 to drive the first cylindrical bar 323 to move away from the support table 11, the first cylindrical bar 323 drives the first triangular block 32 to slide towards the middle of the two L-shaped clamping strips 31 through the L-shaped strip 321, causing the L-shaped clamping strips 31 to slide towards both sides along the two inclined sides of the first triangular block 32 respectively, and at the same time stretching the second spring 314. At this time, the wires are respectively placed between the two L-shaped clamping strips 31. Then, the second rectangular block 324 is driven to drive the first triangular block 32 to slide towards the side away from the middle of the two L-shaped clamping strips 31. At this time, the contraction of the second spring 314 drives the two L-shaped clamping strips 31 to move towards the middle simultaneously, clamping several wires at the same time and maintaining the stability of the wires during welding.

[0027] As Figure 6As shown, third rectangular blocks 325 are fixedly connected to the upper ends of several second rectangular blocks 324 respectively. Second rectangular grooves 3251 are provided on both sides of the third rectangular blocks 325. A fourth rectangular block 3252 is slidably arranged inside the two opposite second rectangular grooves 3251 in common. A third slide rail 326 is slidably arranged on one side of several third rectangular blocks 325 in common. Fifth rectangular blocks 3261 are fixedly connected to both ends of the third slide rail 326 respectively. Several ninth slide rails 37 are fixedly connected to the opposite sides of the first rectangular strip 3 respectively. The fifth rectangular blocks 3261 can slide inside the ninth slide rails 37 respectively.

[0028] Specifically, by driving the fifth rectangular block 3261 to slide inside the ninth slide rail 37 to drive the third slide rail 326 to move towards the side close to the L-shaped clamping strip 31, the third slide rail 326 drives the second rectangular block 324 to move towards the side close to the L-shaped clamping strip 31 through the third rectangular block 325, and multiple second rectangular blocks 324 can be driven to move towards the side close to the L-shaped clamping strip 31 simultaneously. At the same time, the first triangular block 32 is driven to move away from between the two L-shaped clamping strips 31 through the first cylindrical strip 323 and the L-shaped strip 321, which can ensure that multiple groups of L-shaped clamping strips 31 move synchronously for clamping, reducing the phenomenon of wire detachment.

[0029] As Figures 5-6 As shown, second triangular blocks 35 are provided between adjacent two groups of clamping assemblies respectively. Sixth rectangular blocks 36 are provided on one side of the second triangular blocks 35 respectively. Third rectangular grooves 361 are provided on both sides of the sixth rectangular blocks 36. A seventh rectangular block 362 is slidably arranged in the middle of the two opposite third rectangular grooves 361 in common. A fourth slide rail 363 is slidably arranged on one side of several sixth rectangular blocks 36 in common. Eighth rectangular blocks 3631 are fixedly connected to both ends of the fourth slide rail 363 respectively. The eighth rectangular blocks 3631 can slide inside the ninth slide rails 37 respectively. Third springs 331 are sleeved on both ends of the second cylindrical strip 33 respectively.

[0030] Specifically, the distances between the wires to be welded on PCB boards of different models are also different. When using the present invention, by driving the eighth rectangular block 3631 to drive the fourth slide rail 363 to move towards the side close to the L-shaped clamping strip 31, the fourth slide rail 363 drives several second triangular blocks 35 to move towards the middle of the two groups of clamping assemblies through the sixth rectangular blocks 36 at the same time. The two groups of clamping assemblies move along the hypotenuses of the second triangular blocks 35 towards both sides, increasing the distance between several clamping assemblies. On the contrary, when the several second triangular blocks 35 are simultaneously moved towards the side away from the adjacent two clamping assemblies, the distance between the several clamping assemblies can be reduced. The distance between the clamping assemblies can be adjusted, thereby adjusting the distance between the wires, and PCBs of different models can be welded.

[0031] As Figure 2As shown, at one end of two first rectangular bars 3 away from the L-shaped clamping bar 31, a second rectangular bar 38 is fixedly connected. The output end of a second electric telescopic rod 381 is fixedly connected to the lower end of the second rectangular bar 38. The lower end of the second electric telescopic rod 381 is fixedly connected to a third slider 382. The lower end of the third slider 382 is slidably provided with a tenth slide rail 383. The lower end of the tenth slide rail 383 is fixedly connected to a fourth slider 384. The lower end of the fourth slider 384 is slidably provided with an eleventh slide rail 385. The eleventh slide rail 385 is fixedly connected to the upper end of the workbench 1.

[0032] Specifically, after clamping the wire, drive the fourth slider 384 to slide within the eleventh slide rail 385, and at the same time drive the tenth slide rail 383 to move towards the support platform 11. At the same time, the second rectangular bar 38 can be driven to move through the third slider 382 and the second electric telescopic rod 381. The second rectangular bar 38 drives the wire clamped in the middle of the L-shaped clamping bar 31 to move towards the upper end of the PCB board through the first rectangular bar 3. Subsequently, drive the third slider 382 to move within the tenth slide rail 383. The third slider 382 drives the second rectangular bar 38 to move through the second electric telescopic rod 381. The second rectangular bar 38 drives the wire clamped in the middle of the L-shaped clamping bar 31 to move through the first rectangular bar 3 until it moves to the upper end of the welding point on the upper end of the PCB board. Subsequently, drive the second electric telescopic rod 381 to contract to drive the wire to move downward, contact the welding point and then perform welding.

[0033] As Figure 7 shown, at the four corners of the upper end of the support platform 11, first rectangular grooves 111 are respectively provided. A first rectangular plate 113 is slidably provided within the first rectangular grooves 111. Hypotenuse blocks 1132 are respectively slidably provided on the upper ends of the first rectangular plate 113. Inside the hypotenuse blocks 1132, they are fixedly connected to the first rectangular plate 113 through first springs 1131.

[0034] Specifically, after placing the PCB board on the upper end of the support platform 11, drive the first rectangular plates 113 to slide towards the middle at the same time. During the sliding, the hypotenuse blocks 1132 slide along the upper end of the PCB board, so that the hypotenuse blocks 1132 can be pressed against the upper end of the PCB board to fix the PCB board and prevent the PCB board from moving during the welding process.

[0035] As Figure 8 shown, a belt 1133 is rotatably provided on one hypotenuse side of the hypotenuse block 1132.

[0036] Specifically, when driving the first rectangular plates 113 to fix the PCB board in the middle, when the hypotenuse sides of the hypotenuse blocks 1132 are pressed along the upper side of the PCB board, it may cause friction to the PCB board. In this solution, a belt 1133 is provided on one hypotenuse side of the hypotenuse block 1132. When the hypotenuse block 1132 presses the PCB board, the belt 1133 rotates to prevent friction to the PCB board.

[0037] AsFigure 7 As shown in the figure, a first round hole 112 is provided in the middle of the support table 11. A suction cup 1141 is arranged in the first round hole 112. The lower end of the suction cup 1141 is fixedly connected with a first electric telescopic rod 114, and the first electric telescopic rod 114 is fixedly connected with the workbench 1.

[0038] Specifically, after the PCB board is welded, the first electric telescopic rod 114 extends, driving the suction cup 1141 to move upward, jacking up the PCB board, which is convenient for taking the PCB board.

[0039] As Figure 1 shown in the figure, a first slider 21 is fixedly connected to the upper end of the welding head 2. A first slide rail 22 is slidably arranged at the upper end of the first slider 21. Second sliders 23 are fixedly connected to both ends of the first slide rail 22. Second slide rails 24 are respectively slidably arranged on the second sliders 23. Both ends of the second slide rail 24 are fixedly connected to the workbench 1 through support columns 25.

[0040] Specifically, when welding the PCB board, drive the second slider 23 to slide on one side of the second slide rail 24. The second slider 23 drives the welding head 2 to move through the first slide rail 22. Drive the first slider 21 to slide on the first slide rail 22. The first slider 21 drives the welding head 2 to move, and weld the welding points on the upper end of the PCB board one by one.

[0041] Embodiment 2: As Figure 9 shown in the figure, compared with Embodiment 1, another implementation manner of the present invention is: a material taking component is provided on one side of the support table 11. The material taking component includes a conveyor belt 4 installed on the upper end of the workbench 1. L-shaped blocks 41 are respectively arranged on both sides of the conveyor belt 4. Third electric telescopic rods 42 are fixedly connected to the lower ends of the L-shaped blocks 41. A fifth slider 43 is fixedly connected to the lower end of the third electric telescopic rod 42. A twelfth slide rail 44 is slidably arranged at the lower end of the fifth slider 43. Sixth sliders 45 are fixedly connected to both ends of the twelfth slide rail 44. Thirteenth slide rails 46 are respectively slidably arranged on the sixth sliders 45. The thirteenth slide rail 46 is fixedly connected to the workbench 1.

[0042] Specifically, after the steel welding of the PCB board is completed, the temperature of the PCB board is relatively high, and the welding points may not have solidified. When taking it, it is necessary to keep it flat to prevent the wires from falling off. When using the present invention, the first electric telescopic rod 114 extends, driving the suction cup 1141 to move upward, lifting the PCB board upward. Then, the sixth slider 45 is driven to move on the thirteenth slide rail 46 towards the side close to the support table 11. The sixth slider 45 drives the L-shaped block 41 to move towards the side close to the PCB board through the twelfth slide rail 44 until it slides to both sides at the lower end of the PCB board. Subsequently, the suction cup 1141 is driven to move downward, causing the PCB board to fall on the upper end of the L-shaped block 41. Then, the sixth slider 45 drives the L-shaped block 41 to move away from the support table 11 through the third electric telescopic rod 42. The L-shaped block 41 drives the PCB board and moves it to the upper end of the conveyor belt 4. Subsequently, the third electric telescopic rod 42 contracts, driving the L-shaped block 41 to move downward, causing the PCB board to move downward. When the PCB board is about to contact the conveyor belt 4, the fifth slider 43 is driven to drive the L-shaped block 41 to move to both sides through the third electric telescopic rod 42, causing the PCB board to fall on the upper end of the conveyor belt 4 for conveying.

[0043] Working principle: During welding, after placing the PCB board on the upper end of the support table 11, the first rectangular plate 113 is driven to slide towards the middle simultaneously. During the sliding process, the bevel block 1132 slides along the upper end of the PCB, enabling the bevel block 1132 to press against the upper end of the PCB board to fix the PCB board and prevent the PCB board from moving during the welding process. Subsequently, the fifth rectangular block 3261 is driven to slide in the ninth slide rail 37, driving the third slide rail 326 to move towards the side close to the L-shaped clamping strip 31. The third slide rail 326 drives the second rectangular block 324 to move towards the side close to the L-shaped clamping strip 31 through the third rectangular block 325, which can drive multiple second rectangular blocks 324 to move towards the side close to the L-shaped clamping strip 31 simultaneously. At the same time, through the first cylindrical bar 323 and the L-shaped bar 321, the first triangular block 32 is driven to move away from between the two L-shaped clamping strips 31, which can ensure that multiple groups of L-shaped clamping strips 31 move synchronously for clamping. By driving the eighth rectangular block 3631 to drive the fourth slide rail 363 to move towards the side close to the L-shaped clamping strip 31, the fourth slide rail 363 drives a number of second triangular blocks 35 to move towards the middle of the two clamping assemblies through the sixth rectangular block 36. The two clamping assemblies move along the hypotenuse of the second triangular block 35 to both sides, increasing the distance between a number of clamping assemblies. On the contrary, when the second triangular blocks 35 are simultaneously moved away from the side of adjacent two clamping assemblies, the distance between a number of clamping assemblies can be reduced. The distance between the clamping assemblies can be adjusted, thereby adjusting the distance between the wires, and welding of different models of PCBs can be carried out. Drive the second slider 23 to slide on one side of the second slide rail 24. The second slider 23 drives the welding head 2 to move through the first slide rail 22. Drive the first slider 21 to slide on the first slide rail 22. The first slider 21 drives the welding head 2 to move, and weld the welding points on the upper end of the PCB board one by one. When the PCB board welding is completed, the first electric telescopic rod 114 extends, driving the suction cup 1141 to move upward, jacking up the PCB board. Subsequently, drive the sixth slider 45 to move on the thirteenth slide rail 46 towards the support platform 11. The sixth slider 45 drives the L-shaped block 41 to move towards the PCB board through the twelfth slide rail 44 until it slides to both sides of the lower end of the PCB board.
