Description

Technical Field

[0001] The utility model relates to the field of copper foil attachment, in particular to an automatic copper foil attachment device. Background Art

[0002] Copper foil is a kind of negative electrolytic material, a thin and continuous metal foil deposited on the base layer of a circuit board, which serves as the conductor of a PCB. It is easy to adhere to the insulating layer, accept the printed protective layer, and form a circuit pattern after corrosion. Copper foil has the characteristic of low surface oxygen, can adhere to various different substrates, such as metals, insulating materials, etc., and has a wide temperature range of use.

[0003] The automation of copper foil attachment has gradually matured. Generally, in automatic copper foil attachment, a feeder adsorbs the copper foil through a suction cup, and then moves it to the patch component to release the adsorption, thus completing the automatic copper foil attachment. However, in the actual production process, the patch components are sometimes light in weight or have static electricity, etc. And the suction force of the suction cup is generated by a vacuum device. When the suction cup adsorbs the copper foil and moves it to the component, the suction nozzle will adsorb the component due to excessive suction force and separate the component from the conveying device, affecting the automated production and resulting in low efficiency of automatic copper foil attachment. Summary of the Utility Model

[0004] In order to overcome the shortcoming of low efficiency of automatic copper foil attachment, the utility model provides an automatic copper foil attachment device.

A film releasing roller is installed on the top of the working carrier table. A film winding roller is installed in the middle of the working carrier table, and the film winding roller is located below the film tearing platform. A guiding component for guiding the copper foil paper is arranged on the working carrier table. A driving component is installed on the working carrier table, and a feeder is fixedly connected to the driving component. A copper foil suction cup is connected to the feeder, and the copper foil suction cup is located above the film tearing platform. A support frame is further included, and the support frame is located at the right end of the working carrier table. A chain conveyor is installed on the support frame, and a plurality of attachment carriers are evenly and fixedly connected to the chain conveyor. A toothed ring is rotatably installed in the middle of the attachment carrier. Rack bars are symmetrically and slidably installed on the attachment carrier with the toothed ring as the center. A chute cooperating with the rack bar is opened on the attachment carrier. Both rack bars are engaged with the toothed ring. One end of the rack bar is connected with an arc-shaped clamping block, and the two arc-shaped clamping blocks are symmetrically distributed with the toothed ring as the center. An L-shaped push rod is fixedly connected to the rack bar at the rear end of the attachment carrier, and the L-shaped push rod slidably penetrates through the right end of the attachment carrier.

[0006] In addition, particularly preferably, a return spring is connected between the attachment carrier and the L-shaped push rod.

[0013] The beneficial effects of the present utility model are as follows: 1. The present utility model drives the arc-shaped clamping blocks through the L-shaped push rod, which can realize the clamping and fixing of components. By setting the circular limiting frame and the short-range slideway, when the component is conveyed to directly to the right of the feeder, the L-shaped push rod pushes the arc-shaped clamping blocks, thereby automatically clamping and fixing the component, improving the automation level, preventing the copper foil suction cup from adsorbing the component and taking it away from the attaching carrier, so as to ensure the orderly progress of the automatic copper foil attachment of the component by the copper foil suction cup, and thus improving the efficiency of automatic copper foil attachment.

Detailed implementation manners

[0024] To make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0025] Embodiment 1: A copper foil automatic attaching device, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7As shown in the figure, it includes a working stage 1. A film tearing platform 2 is installed in the middle of the working stage 1. A film releasing roller 3 is installed on the top of the working stage 1. A film winding roller 31 is installed in the middle of the working stage 1. The film winding roller 31 is located below the film tearing platform 2. A guiding component 32 for guiding the copper foil paper is arranged on the working stage 1. A driving component 4 is installed on the working stage 1. A feeder 5 is fixedly connected to the driving component 4. A copper foil suction cup 51 is connected to the feeder 5. The copper foil suction cup 51 is located above the film tearing platform 2. It also includes a support frame 6. The support frame 6 is located at the right end of the working stage 1. A chain conveyor 7 is installed on the support frame 6. A plurality of attaching carriers 9 are evenly and fixedly connected to the chain conveyor 7. A toothed ring 91 is rotatably installed in the middle of the attaching carrier 9. Rack bars 92 are symmetrically and slidably installed on the attaching carrier 9 with the toothed ring 91 as the center. Sliding grooves cooperating with the rack bars 92 are formed on the attaching carrier 9. Both rack bars 92 are engaged with the toothed ring 91. One end of each rack bar 92 is connected to an arc-shaped clamping block 93. A torsion spring is connected between the arc-shaped clamping block and the rack bar. The two arc-shaped clamping blocks 93 are symmetrically distributed with the toothed ring 91 as the center. An L-shaped push rod 94 is fixedly connected to the rack bar 92 at the rear end of the attaching carrier 9. The L-shaped push rod 94 slidably penetrates through the right end of the attaching carrier 9.

[0026] When the copper foil automatic attaching production line is working, the copper foil release paper is released from the film releasing roller 3 and guided to the film tearing platform 2 by the guiding component 32. The chain conveyor 7 and the driving component 4 are started. The chain conveyor drives the attaching carriers 9 to start circulating. The components to be attached with copper foil flow in from the upstream equipment onto the attaching carriers 9 of the chain conveyor 7. The driving component 4 drives the copper foil suction cup 51 to adsorb the copper foil on the film tearing platform 2. After the feeder 5 detects that the component product reaches directly to the right of the copper foil suction cup 51, at this time, the worker stands on the right side of the chain conveyor 7 and aligns with the feeder 5. The worker pushes the L-shaped push rod 94 to make the two arc-shaped clamping blocks 93 clamp and fix the component on the right side of the copper foil suction cup 51. The release paper is recycled onto the film winding roller 31. The copper foil suction cup 51 moves the adsorbed copper foil to the component and releases the adsorption, so that the copper foil is attached to the corresponding position of the component. The arc-shaped clamping block 93 can prevent the component from being sucked away when the copper foil suction cup 51 moves back, thus ensuring the orderly progress of automated production. After the copper foil suction cup 51 moves back, it pulls the L-shaped push rod 94 to release the clamping and fixing of the two arc-shaped clamping blocks 93 on the component, and then clamps and fixes the next component and automatically attaches the copper foil. When the arc-shaped clamping block 93 tightly adheres to the component for fixed clamping, the torsion spring 96 can enable the arc-shaped clamping block 93 to rotate according to the size of the component, thus ensuring the production quality of the component.

[0027] Embodiment 2: As Figure 5 and Figure 6As shown in the figure, a ring-shaped limiting frame 8 is fixedly connected to the right end of the support frame 6. A short-range slideway 81 is provided in the middle of the right side of the ring-shaped limiting frame 8. Both ends of the short-range slideway 81 are provided with inclined surfaces. The short-range slideway 81 is located directly to the right of the copper foil suction cup 51; a long-range slideway 82 is provided in the lower right part of the ring-shaped limiting frame 8. The long-range slideway 82 is semi-circular. Both ends of the long-range slideway 82 are provided with inclined surfaces. The two inclined surfaces correspond to the feeding turning point and the discharging turning point of the chain conveyor 7; the two arc-shaped clamping blocks 93 are distributed from the front left to the back right. A return spring 95 is connected between the attaching carrier 9 and the L-shaped push rod 94. The return spring 95 is located outside the attaching carrier 9. The rightmost end of the L-shaped push rod 94 fits against the right side of the ring-shaped limiting frame 8; a guide plate 10 is fixedly connected to the front end of the support frame 6. A receiving frame 11 is arranged below the guide plate 10. The guide plate 10 is located in front of the left of the ring-shaped limiting frame 8.

[0028] When the copper foil automatic attaching production line is operating, when the component to be attached with copper foil reaches the short-range slideway 81 of the ring-shaped limiting frame 8, the L-shaped push rod 94 slides into the short-range slideway 81 from the inclined surface, so that the ring-shaped limiting frame 8 releases the restriction on the L-shaped push rod 94. The return spring 95 resets. The L-shaped push rod 94 pushes the rack 92 to slide leftward, and drives the front-side rack 92 to slide rightward through the toothed ring 91, so that the two arc-shaped clamping blocks 93 clamp and fix the component, reducing manual operation and improving the automation level of the equipment. At the same time, the feeder 5 detects that the component product reaches directly to the right of the copper foil suction cup 51. The copper foil suction cup 51 moves the adsorbed copper foil to the component and releases the adsorption, so that the copper foil is attached to the corresponding position of the component. Subsequently, the chain conveyor 7 drives the L-shaped push rod 94 to slide out of the short-range slideway 81. The ring-shaped limiting frame 8 stretches the return spring 95 again, so that the two arc-shaped clamping blocks 93 release the clamping and fixing of the component, and carry out the automatic copper foil attaching work for the next component; the component with the attached copper foil is transported to the discharging turning point at the front end of the conveyor along with the attaching carrier 9. The component falls out of the attaching carrier 9 due to its own gravity. The component falls onto the guide plate 10 and into the receiving frame 11, which is convenient for collecting the components with the attached copper foil. At this time, the attaching carrier 9 is in an empty state. The L-shaped push rod 94 slides into the long-range slideway 82 along the inclined surface on the ring-shaped limiting frame 8. The return spring 95 resets, which can extend the service life of the return spring 95. The attaching carrier 9 continues to be transported along with the chain conveyor 7 until the empty attaching carrier 9 is transported to the feeding turning point. The L-shaped push rod 94 slides out of the long-range slideway 82 along the inclined surface, and the return spring 95 is stretched, so that the two arc-shaped clamping blocks 93 expand outward. The upstream equipment puts a new batch of components into the attaching carrier 9 to ensure the smooth progress of the cyclic production line operation.
