Description
Technical Field
[0001] The utility model belongs to the technical field of PCBA processing, and particularly relates to a PCBA gold finger film covering tooling. Background Technique
[0002] PCBA is the whole process of PCB bare board through SMT component mounting or DIP plug-in. It is an important electronic component, a support for electronic components, and a provider of circuit connections for electronic components.
[0003] With the integration and miniaturization of electronic products, the distance between the display type control board components and the gold finger area is getting closer and closer. When performing three-proof atomization coating, the gold finger will be glued. The defective rate is relatively high. If it is necessary to ensure that the gold finger is not glued, it can only be prevented by manually attaching high-temperature tape.
[0004] When manually attaching the high-temperature tape, the production efficiency is low, and the attachment accuracy can only be controlled manually. After the attachment is offset, the glue will soak along the gap between the PCB board and the high-temperature tape, resulting in defective products. Content of the Utility Model
[0005] The purpose of the utility model is to provide a PCBA gold finger film covering tooling to solve the problems of low production efficiency of manually attaching high-temperature tape, only being able to be controlled manually for attachment accuracy, and the glue soaking along the gap between the PCB board and the high-temperature tape after the attachment is offset, resulting in defective products, as mentioned in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A PCBA gold finger film covering tooling, including a tooling table. On the upper surface of the tooling table, there are two anti-offset tracks. The upper surface of the anti-offset tracks is provided with a number of embedded grooves. Bolts are installed in the embedded grooves in a threaded manner. On one side of the upper surface of the tooling table, there are a number of threaded grooves. One of the anti-offset tracks is fixed on the surface of the tooling table through bolts and threaded grooves, and the other anti-offset track is movably arranged on the surface of the tooling table through bolts. On the upper surface of the tooling table, two brackets and two support plates are fixed. Installation grooves are provided on the brackets. A multi-axis anti-offset roller is passed through the two installation grooves. A silica gel anti-offset wheel and a film covering roller are arranged between the two support plates. The silica gel anti-offset wheel is rotatably installed between the two support plates. Installation plates are installed at both ends of the roller shaft of the film covering roller. Slideways for the installation plates to move up and down are provided on the support plates.
[0007] With the above solution, by setting two anti-deviation tracks, one anti-deviation track is fixedly arranged and the other anti-deviation track is movably arranged, the limit fixation and anti-deviation of the product can be realized. By using the multi-axis anti-deviation roller in cooperation with the silicone anti-deviation wheel, the deviation of the tape before attachment can be prevented, which may affect the attachment effect. By using the film covering roller in cooperation with the sliding rod and the spring, the presence of the spring can drive the film covering roller to always press the product and perform film covering, ensuring good operation stability. By setting the support roller in cooperation with the anti-deviation track, the stable transmission of the product tape can be ensured on the premise that the anti-deviation track fixes the product tape, ensuring the smooth and orderly progress of the operation.
[0008] As a preferred embodiment, a plurality of trapezoidal sliders are fixedly arranged on the lower surface of the movably arranged anti-deviation track. The trapezoidal sliders are arranged opposite to the bolts and are provided with through holes for the bolts to pass through. Trapezoidal chutes for the trapezoidal sliders to slide are arranged on the upper surface of the tooling table, and the tail ends of the bolts corresponding to the trapezoidal sliders are in contact with the inner walls of the trapezoidal chutes.
[0009] With the above solution, by using the trapezoidal slider in cooperation with the trapezoidal chute, when the bolt is loosened, the anti-deviation track is unlocked and can slide in the trapezoidal chute through the trapezoidal slider. After sliding and adjusting the position, the bolt can be tightened to realize the position extrusion and locking of the anti-deviation track. The locking structure is simple, the operation and adjustment are convenient, and the use of the trapezoidal slider in cooperation with the trapezoidal chute can prevent the anti-deviation track from detaching from the tooling table.
[0010] As a preferred embodiment, a plurality of support rollers are rotatably installed on the side surface of the anti-deviation track, and the support rollers on the two anti-deviation tracks are arranged opposite to each other.
[0011] With the above solution, the setting of the support rollers can ensure the stable transmission of the product after the product is fixed.
[0012] As a preferred embodiment, the mounting seats are arranged in a fitting manner on the upper surface of the bracket. The mounting seats are provided with pins inserted therein. Slots for the pins to be inserted are arranged on the surface of the bracket, and the lower surface of the mounting seat has a protruding portion inserted into the mounting groove.
[0013] With the above solution, by using the mounting seat in cooperation with the pin, the installation operation of the multi-axis anti-deviation roller is facilitated, and the multi-axis anti-deviation roller is prevented from tilting and shaking.
[0014] As a preferred embodiment, two limiting rings are installed on the outer surfaces of both ends of the roller shaft of the multi-axis anti-deviation roller, and the two limiting rings at the same side position are respectively arranged in a fitting manner on both side surfaces of the bracket at the same side position.
[0015] With the above solution, the setting of the limiting rings can achieve a horizontal limiting effect, further preventing the horizontal movement of the multi-axis anti-deviation roller.
[0016] As a preferred embodiment, a sliding rod is slidably mounted on the upper surface of the support plate. A limit disc is fixedly mounted at the top end of the sliding rod. The bottom end of the sliding rod extends to the inner wall of the slideway and is fixedly connected to the mounting plate. A spring is fixedly mounted between the limit disc and the support plate.
[0017] With the above solution, the arrangement of the sliding rod can ensure the stable up-and-down sliding of the mounting plate, and the elasticity of the spring can ensure that the film covering roller is always subjected to a downward acting force, so that the film covering roller can stably fit the surface of the product for film covering operation.
[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0019] This PCBA gold finger film covering tooling can realize the limit and anti-deviation fixation of the product by setting two anti-deviation tracks, one of which is fixedly arranged and the other is movably arranged. By using the multi-axis anti-deviation roller in cooperation with the silicone anti-deviation wheel, it is possible to prevent the tape from shifting before attachment and affecting the attachment effect, and by using the film covering roller in cooperation with the sliding rod and the spring, the presence of the spring can drive the film covering roller to always press the product and perform film covering, ensuring good operation stability;

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0026] Please refer to Figures 1-4, the present utility model provides a PCBA gold finger film covering tooling, which includes a tooling table 1. On the upper surface of the tooling table 1, there are two anti-deviation tracks 2. A plurality of embedded grooves 5 are opened on the upper surface of the anti-deviation tracks 2. Bolts 3 are threadedly installed in the embedded grooves 5. A plurality of threaded grooves 4 are opened on one side of the upper surface of the tooling table 1. One of the anti-deviation tracks 2 is fixed on the surface of the tooling table 1 through the bolts 3 and the threaded grooves 4, and the other anti-deviation track 2 is movably arranged on the surface of the tooling table 1 through the bolts 3. Two brackets 6 and two support plates 9 are fixed on the upper surface of the tooling table 1. Installation grooves 7 are opened on the brackets 6. A multi-axis anti-deviation roller 8 is passed through the two installation grooves 7. A silicone anti-deviation wheel 10 and a film covering roller 12 are arranged between the two support plates 9. The silicone anti-deviation wheel 10 is rotatably installed between the two support plates 9. Installation plates 13 are installed at both ends of the roller shaft of the film covering roller 12. Slideways 11 for the up and down movement of the installation plates 13 are opened on the support plates 9.
[0027] A plurality of trapezoidal sliders 14 are fixed on the lower surface of the movably arranged anti-deviation track 2. The trapezoidal sliders 14 are arranged opposite to the bolts 3 and are provided with through holes for the bolts 3 to pass through. Trapezoidal chutes 15 for the trapezoidal sliders 14 to slide are opened on the upper surface of the tooling table 1. The tail ends of the bolts 3 corresponding to the trapezoidal sliders 14 are attached to the inner walls of the trapezoidal chutes 15. By using the trapezoidal sliders 14 in cooperation with the trapezoidal chutes 15, when the bolts 3 are loosened, the anti-deviation track 2 is unlocked and can slide in the trapezoidal chutes 15 through the trapezoidal sliders 14. After the position is adjusted by sliding, the bolts 3 can be tightened to realize the position extrusion locking of the anti-deviation track 2. The locking structure is simple, the operation and adjustment are convenient, and the use of the trapezoidal sliders 14 in cooperation with the trapezoidal chutes 15 can prevent the anti-deviation track 2 from detaching from the tooling table 1.
[0028] A plurality of support rollers 16 are rotatably installed on the side surface of the anti-deviation track 2. The support rollers 16 on the two anti-deviation tracks 2 are arranged oppositely. The setting of the support rollers 16 can fix the product and realize the stable transmission of the product.
[0029] An installation seat 22 is laid on the upper surface of the bracket 6 in a fitting manner. A pin 17 is inserted into the installation seat 22. A slot for the pin 17 to be inserted is opened on the surface of the bracket 6. The lower surface of the installation seat 22 has a protruding part inserted into the installation groove 7. By using the installation seat 22 in cooperation with the pin 17, the installation operation of the multi-axis anti-deviation roller 8 is facilitated, and the multi-axis anti-deviation roller 8 can be prevented from tilting and shaking.
[0030] Two limit rings 18 are installed on the outer surfaces of both ends of the roller shaft of the multi-axis anti-deviation roller 8. The two limit rings 18 at the same side position are respectively laid on both side surfaces of the bracket 6 at the same side position in a fitting manner. The setting of the limit rings 18 can play a horizontal limiting effect and further prevent the horizontal movement of the multi-axis anti-deviation roller 8.
[0031] A sliding rod 19 is slidably mounted on the upper surface of the support plate 9. A limit disk 20 is fixedly mounted at the top end of the sliding rod 19. The bottom end of the sliding rod 19 extends to the inner wall of the slideway 11 and is fixedly connected to the mounting plate 13. A spring 21 is fixedly mounted between the limit disk 20 and the support plate 9. The arrangement of the sliding rod 19 can ensure the stable up-and-down sliding of the mounting plate 13. The elasticity of the spring 21 can ensure that the film covering roller 12 is always subjected to a downward acting force, so that the film covering roller 12 can stably fit on the surface of the product for film covering operation.
[0032] During use, first loosen the bolt 3 on the anti-deviation track 2 which is movably arranged. After unlocking the anti-deviation track 2, slide the trapezoidal slider 14 in the trapezoidal chute 15 until the two anti-deviation tracks 2 just clamp the product tape tightly, and then tighten the bolt 3 for locking to realize the fixed clamping of the product tape. The support roller 16 is used to cooperate to realize the transmission of the product tape. The tape is transmitted through the multi-axis anti-deviation roller 8 and the silicone anti-deviation wheel 10 to realize the anti-deviation before the tape is attached. At the same time, the elasticity of the spring 21 is always downward, and then acts on the film covering roller 12 through the mounting plate 13, so that the film covering roller 12 always fits on the product tape for film covering. When the multi-axis anti-deviation roller 8 needs to be disassembled subsequently, pull out the pin 17 to remove the mounting seat 22, and then take out the multi-axis anti-deviation roller 8 upward.
