Description

Technical Field

[0002] With the advancement of technology and the rapid development of productivity, electronic devices such as mobile phones, computers, and televisions have become ubiquitous in people's daily lives, greatly facilitating their lives. LED LCD screens are one of the key components of these electronic devices, used to display images. In actual production, the screen panel and PCB board need to be connected via ribbon cables to achieve output and control effects.

[0003] Currently, when soldering displays, the ribbon cable is first placed on the surface of the display and positioned using a specific fixture so that both ends of the ribbon cable are aligned with the soldering ports on the display and PCB board surfaces, respectively.

Detailed Implementation

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0028] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0029] like Figure 1 , Figure 2 , Figure 5 , Figure 6The diagram shows the structure of an LED display processing and welding equipment according to an embodiment of the present invention. It includes a base 1, a vertical plate 11 fixedly mounted on the surface of the base 1, a fixing ring 2 rotatably mounted on the side of the vertical plate 11, a plurality of equally spaced placement plates 3 on the surface of the fixing ring 2, two opposing laser soldering machines 4 on the side of the vertical plate 11, a conveying mechanism 5 on the surface of the base 1, the conveying mechanism 5 including a rotating component 51 and a balancing component 52, the rotating component 51 being located on the surface of the vertical plate 11 and connected to the fixing ring 2, the rotating component 51 controlling the fixing ring 2 to rotate intermittently around its own axis, the balancing component 52 being located on the side wall of the fixing ring 2 and connected to the placement plates 3, the balancing component 52 controlling the placement plates 3 to remain horizontal, a clamping mechanism 6 on the surface of the placement plates 3, the clamping mechanism 6 including a pressure plate 61, a positioning component 62, and an adjusting component 63, the positioning component 62 being located on the surface of the placement plates 3 and connected to the pressure plate 61, the positioning component 62 being located on the surface of the placement plates 3 and connected to the pressure plate 61, the positioning component 62 being located on the side wall of the fixing ring 2 and connected to the placement plates 3 ... 2 is used to support the pressure plate 61 above the shelf 3. The adjusting component 63 is connected to the positioning component 62. The adjusting component 63 is used to adjust the relative position of the pressure plate 61 and the shelf. A storage box 7 is fixedly installed on the side wall of the vertical plate 11. The storage box 7 passes through the inner cavity of the fixing ring 2. Two oppositely distributed fixing cylinders 71 are fixedly installed on the bottom wall of the storage box 7. A discharge cylinder 72 is slidably installed in the vertical direction inside the fixing cylinder 71. The discharge cylinder 72 has a top cavity 721 opened from bottom to bottom. The material storage chamber 722 and the material conveying chamber 723 are provided. The material discharge mechanism 8 is provided in the material discharge cylinder 72. The material discharge mechanism 8 includes a sealing component 81 and a guide component 82. The sealing component 81 is located in the material storage chamber 722 and is used to control the bottom opening of the material storage chamber 722 to remain closed. The guide component 82 is connected to the sealing component 81 and is used to control the bottom opening of the material storage chamber 722 to switch to a through state and further control the quantitative discharge of material from the material storage chamber 722.

[0030] A batch of solder is added to the storage box 7. The sealing component 81 seals the bottom opening of the storage cavity 722, allowing a measured amount of solder to fall into the storage cavity 722. The fixing ring 2 positions multiple placement plates 3. The display screen to be soldered is placed flat on the surface of the placement plate 3, and the ribbon cable is placed on the surface of the display screen. The positioning component 62 and the adjusting component 63 cooperate to easily adjust the position of the two pressure plates 61. The two pressure plates 61 can easily squeeze and position the two sides of the ribbon cable on the surface of the display screen, so that one end of the ribbon cable is aligned with the soldering port on the surface of the display screen, and the other end of the ribbon cable is aligned with the soldering port on the surface of the PCB board. After the position of the ribbon cable is fixed, the rotating component 51 controls the fixing ring 2 to rotate a certain angle (a certain angle is 300 degrees). The fixed ring 2 rotates at an angle of 60 degrees (equally divided by the number of placement plates 3). When the fixed ring 2 rotates, it drives multiple placement plates 3 to rotate synchronously. When the placement plate 3 carrying the display screen rotates to the lowest position, the guide assembly 82 controls the lower material cylinder 72 to move vertically downward. When the bottom end of the lower material cylinder 72 is close to the welding ports on both sides of the ribbon cable, the guide assembly 82 controls the bottom opening of the storage cavity 722 to switch to the through state, and simultaneously controls the top opening of the storage cavity 722 to switch to the closed state. A certain amount of solder in the storage cavity 722 falls freely and passes through the conveying cavity 723, finally falling onto the surface of the welding port. The rotating assembly 51 intermittently controls the fixed ring 2 and the placement plates 3 to rotate. When the placement plate 3 and the display screen on the surface of the placement plate 3 rotate to the highest position, the laser soldering machine 4 can automatically melt and solder the solder at both ends of the ribbon cable. During the period when the fixed ring 2 and the placement plate 3 stop rotating, the laser soldering machine 4 performs soldering processing. The operator can remove the soldered display screen from the surface of the placement plate 3 and replace the display screen to be soldered on the surface of the placement plate 3. This cycle can be repeated to continuously solder multiple display screens, effectively improving soldering efficiency and soldering quality.

[0031] like Figure 1 , Figure 2 , Figure 8 As shown, in a preferred embodiment of the present invention, the rotating assembly 51 includes a positioning gear ring 511 fixedly mounted on the annular sidewall of the fixing ring 2, a motor 512 fixedly mounted on the surface of the vertical plate 11, and a transmission gear disc 513 fixedly mounted on the output shaft of the motor 512, the transmission gear disc 513 being meshed with the positioning gear ring 511.

[0032] In use, the motor 512 drives the transmission gear 513 to rotate. The transmission gear 513 meshes with the positioning gear ring 511, which can drive the fixed ring 2 to rotate synchronously around its own axis. When the fixed ring 2 rotates to a certain angle, the motor 512 stops running and controls the transmission gear 513 to stop rotating. At this time, the fixed ring 2 and the shelf 3 stop moving synchronously and remain stationary.

[0033] like Figure 2 , Figure 3 As shown, in a preferred embodiment of the present invention, the balancing component 52 includes a plurality of bearing columns 521 rotatably mounted on the side wall of the fixing ring 2 and distributed in an annular pattern at equal intervals. The shelf 3 is fixedly mounted on the surface of the bearing columns 521. A bracket 522 is fixedly mounted on the bottom wall of the shelf 3. A counterweight 523 is fixedly mounted on the bottom end of the bracket 522.

[0034] The supporting column 521 initially positions the shelf 3 at the side wall of the fixing ring 2. The counterweight 523 and the bracket 522 cooperate to further position the shelf 3. When the fixing ring 2 rotates, the counterweight 523 controls the shelf 3 to always remain horizontal, which facilitates the welding of the display screen on the surface of the shelf 3.

[0035] like Figure 2 , Figure 3 , Figure 4 As shown, in a preferred embodiment of the present invention, the positioning component 62 includes two L-shaped rods 521 arranged side by side on the surface of the shelf 2. A vertical cylinder 622 is fixedly installed at the end of the L-shaped rod 521 away from the shelf 2. A telescopic column 623 is slidably installed inside the vertical cylinder 622. The bottom end of the telescopic column 623 extends to the bottom of the vertical cylinder 622 and is connected to the pressure plate 61.

[0036] The positioning component 62 positions the pressure plate 61 above the placement plate 3. Initially, the pressure plate 61 is at its highest position above the placement plate 3. After the display screen and ribbon cable are placed on the surface of the placement plate 3, the position of the ribbon cable is adjusted so that both ends of the ribbon cable are aligned with the soldering ports on the display screen and PCB board surfaces, respectively. After the ribbon cable is adjusted to the appropriate position, the adjustment component 63 controls the pressure plate 61 to move downward and further applies a vertical downward pushing force to the pressure plate 61, which can further fix the position of the ribbon cable. This facilitates subsequent soldering of the two ends of the ribbon cable. After the display screen is soldered, the adjustment component 63 controls the pressure plate 61 to move vertically upward back to its original position. At this time, the pressure plate 61 separates from the display screen and ribbon cable, and the operator can easily remove the soldered display screen from the surface of the placement plate 3.

[0037] like Figure 2 , Figure 3 , Figure 4 As shown, in a preferred embodiment of the present invention, the adjusting component 63 includes a plurality of annularly distributed guide grooves 631 opened on the inner side wall of the vertical cylinder 622, a limiting groove 632 opened on the top wall of the vertical cylinder 622, a plurality of limiting blocks 633 fixedly installed on the surface of the telescopic column 623, and a compression spring 634 fixedly installed at the bottom end of the vertical cylinder 622, the telescopic end of the compression spring 634 being connected to the pressure plate 61.

[0038] Initially, the limiting block 633 on the surface of the telescopic column 623 is inserted into the limiting groove 632 at the top of the vertical cylinder 622. At this time, the compression spring 634 is in a compressed state, and the pressure plate 61 is in the highest position. After the display screen and the ribbon cable are placed on the surface of the shelf 3, the operator pulls the telescopic column 623 upward to separate the limiting block 633 from the limiting groove 632. After the limiting block 633 and the limiting groove 632 are separated, the operator rotates the telescopic column 623 to align the limiting block 633 with the guide groove 631, releases the telescopic column 623, and the compression spring 634 pushes the telescopic column 623 and the pressure plate 61 to move vertically downward. At this time, the limiting block 633 on the surface of the telescopic column 623 moves downward synchronously in the guide groove 631. The compression spring 634 applies a vertical downward pushing force to the pressure plate 61, and the pressure plate 61 can stably fix the position of the ribbon cable. After welding is completed, the staff pulls the telescopic column 623 vertically upward and further rotates the telescopic column 623 so that the limiting block 633 is inserted into the limiting groove 632. At this time, the pressure plate 61 is in the highest position again, and the staff can easily remove the welded display screen from the surface of the shelf 3.

[0039] like Figure 5 , Figure 6 , Figure 7 As shown, in a preferred embodiment of the present invention, the sealing assembly 81 includes a central rod 811 slidably mounted vertically within a storage cavity 722. A bottom sealing ball 812 is fixedly mounted at the bottom end of the central rod 811, and the top end of the central rod 811 extends into a top cavity 721. A central plate 813 is fixedly mounted within the top cavity 721, and a return spring 814 is fixedly mounted on the bottom wall of the central plate 813. The telescopic end of the return spring 814 is connected to the top end of the central rod 811.

[0040] The return spring 814 applies a vertical downward thrust to the center rod 811, which positions the bottom sealing ball 812. The bottom sealing ball 812 seals the bottom opening of the storage chamber 722. The solder in the storage box 7 is filled into the fixed cylinder 71 and the top cavity 721. A fixed amount of solder passes through the top cavity 721 and moves further into the storage chamber 722. When the placement plate 3 and the display screen move to the lowest position, the guide assembly 82 controls the lower cylinder 72 to move vertically downward. When the bottom end of the lower cylinder 72 is close to the welding port on both sides of the ribbon cable, the guide assembly 82 controls the center rod 811 to move vertically upward. The center rod 811 drives the bottom sealing ball 812 to move upward synchronously. At this time, the bottom opening of the storage chamber 722 switches to the through state, and simultaneously controls the top opening of the storage chamber 722 to switch to the closed state. A fixed amount of solder in the storage chamber 722 falls freely and passes through the conveying chamber 723 and finally falls onto the surface of the welding port. After the tin material is fed in, the guide assembly 82 controls the lower cylinder 72 to move vertically upward to its original position. At this time, the bottom opening of the storage chamber 722 switches to the closed state again, and the top opening of the storage chamber 722 switches to the open state again. A fixed amount of tin material will pass through the top cavity 721 and fall into the storage chamber 722 again, which is convenient for feeding again.

[0041] like Figure 5 , Figure 6 , Figure 7 As shown, in a preferred embodiment of the present invention, the guide assembly 82 includes a top sealing ball 821 fixedly mounted on the surface of a central rod 811, a traction cable 822 fixedly mounted on the side wall of the top cavity 721, the bottom end of the traction cable 822 being connected to the top end of the central rod 811, an electric telescopic rod 823 fixedly mounted on the bottom wall of the storage box 7, a connecting rod 824 fixedly mounted on the telescopic end of the electric telescopic rod 823, and the two ends of the connecting rod 824 being connected to the discharge cylinder 72 respectively.

[0042] The center rod 811 positions the top sealing ball 821 and the bottom sealing ball 812. When solder needs to be added, the electric telescopic rod 823 pushes the connecting rod 824 to move vertically downward. The connecting rod 824 drives the feeding cylinder 72 to move downward synchronously. When the feeding cylinder 72 moves downward, it continuously tensions the traction cable 822. Initially, the traction cable 822 is in a slack state. When the bottom end of the feeding cylinder 72 is close to the welding ports on both sides of the ribbon cable, the traction cable 822 moves to its limit length and is in a taut state. The traction cable 822 pulls the center rod 811 to move upward relative to it in the storage cavity 722. At this time, the top sealing ball 821 controls the top opening of the storage cavity 722 to switch to a closed state, and the bottom sealing ball 812 controls the bottom opening of the storage cavity 722 to switch to a through state. A certain amount of solder in the storage cavity 722 falls freely and passes through the conveying cavity 723 and finally falls onto the surface of the welding port.

[0043] like Figure 3, Figure 4 As shown, in a preferred embodiment of the present invention, a pull ring 9 is fixedly installed at the top of the telescopic column 623.

[0044] like Figure 1 , Figure 2 , Figure 8 As shown, in a preferred embodiment of the present invention, the side wall of the vertical plate 11 is provided with an annular limiting groove, and the side wall of the fixed ring 2 is fixedly installed with a limiting ring 10, which is rotatably installed in the limiting groove.

[0045] The limiting ring 10 and the limiting groove work together to effectively improve the stability of the fixed ring 2 when it rotates.

[0046] like Figure 1 , Figure 2 , Figure 8 As shown, in a preferred embodiment of the present invention, a plurality of second magnetic positioning plates distributed in a ring at equal intervals are fixedly installed on the side wall of the vertical plate 11, and a plurality of first magnetic positioning plates 12 distributed in a ring at equal intervals are fixedly installed on the side wall of the fixing ring 2.

[0047] When the fixed ring 2 rotates, it drives the first magnetic positioning piece 12 to rotate synchronously. At this time, the first magnetic positioning piece 12 and the second magnetic positioning piece separate from each other. When the motor 512 stops running, the first magnetic positioning piece 12 and the second magnetic positioning piece are connected again to form a whole through magnetic attraction. The fixed ring 2 stops rotating at the same time, which effectively improves the stability of the fixed ring 2.

[0048] The working principle of this invention is as follows: a batch of tin material is put into the storage box 7, and a certain amount of tin material falls into the storage cavity 722. The fixing ring 2 positions multiple placement plates 3. The display screen to be welded is placed flat on the surface of the placement plate 3. The ribbon cable is placed on the surface of the display screen. The position of the ribbon cable is adjusted so that both ends of the ribbon cable are aligned with the welding ports on the display screen and the PCB board surface, respectively. After the ribbon cable is adjusted to the appropriate position, the operator pulls the telescopic column 623 upward to separate the limiting block 633 from the limiting groove 632. After the limiting block 633 and the limiting groove 632 are separated, the operator rotates the telescopic column 623 to align the limiting block 633 with the guide groove 631. The telescopic column 623 is released, and the compression spring 634 pushes the telescopic column 623 and the pressure plate 61 to move vertically downward. At this time, the limiting block 633 on the surface of the telescopic column 623 moves downward synchronously in the guide groove 631. The compression spring 634 applies a vertical downward pushing force to the pressure plate 61, and the pressure plate 61 can stably fix the position of the ribbon cable.

[0049] Motor 512 drives transmission gear 513 to rotate. Transmission gear 513 meshes with positioning gear ring 511, which can drive fixed ring 2 to rotate synchronously around its own axis. When fixed ring 2 rotates a certain angle, motor 512 stops running and controls transmission gear 513 to stop rotating. At this time, fixed ring 2 and shelf 3 both stop moving synchronously and remain stationary.

[0050] When the display screen mounting plate 3 rotates to its lowest position, the electric telescopic rod 823 pushes the connecting rod 824 to move vertically downward. The connecting rod 824 drives the feeding cylinder 72 to move downward synchronously. As the feeding cylinder 72 moves downward, it continuously tensions the traction cable 822. Initially, the traction cable 822 is in a slack state. When the bottom end of the feeding cylinder 72 approaches the welding ports on both sides of the ribbon cable, the traction cable 822 moves to its maximum length and is in a taut state. The traction cable 822 pulls the central rod 811 to move upward relative to it in the storage cavity 722. At this time, the top sealing ball 821 controls the top opening of the storage cavity 722 to switch to a closed state, and the bottom sealing ball 812 controls the bottom opening of the storage cavity 722 to switch to a through state. A certain amount of solder in the storage cavity 722 falls freely and passes through the feeding cavity 723 and finally falls onto the surface of the welding port. When the mounting plate 3 and the display screen on its surface rotate to their highest position, the laser soldering machine 4 can automatically melt and solder the solder at both ends of the ribbon cable. During the period when the fixing ring 2 and the mounting plate 3 stop rotating, the laser soldering machine 4 performs the soldering process. The operator can remove the soldered display screen from the surface of the mounting plate 3 and replace the display screen to be soldered on the surface of the mounting plate 3. This cycle can be repeated to continuously solder multiple display screens, effectively improving soldering efficiency and soldering quality.

[0051] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
