Description

Technical Field

[0001] This invention relates to the field of post-cutting processing technology for flexible circuit boards, and more particularly to a temporary storage device for flexible circuit board unloading. Background Technology

[0002] In the cutting and processing of flexible circuit boards, a device such as... is first placed on the operating table of the laser cutting machine. Figure 1 , Figure 10 The positioning paper 6 shown has a square groove 61 in the middle, and then... Figure 1 , Figure 2 The panel 7 shown has multiple flexible circuit boards 8 arranged in a rectangular array and is placed in a square groove 61. At the same time, in each row of the panel 7, each pair of adjacent flexible circuit boards 8 are arranged facing different directions.

[0003] Currently, after cutting, the flexible circuit boards are still manually unloaded, requiring each board to be removed individually. This method necessitates workers spending a considerable amount of time next to the laser cutting machine. Furthermore, the flexible circuit boards require testing, surface treatment, and cleaning after cutting, but currently they are simply placed randomly in a collection basket, making subsequent retrieval inconvenient. Summary of the Invention

[0004] To address the aforementioned shortcomings, this invention provides a flexible circuit board unloading and temporary storage device that can automatically complete the batch unloading of flexible circuit boards and temporarily store them in the same direction for easy subsequent use.

[0005] In order to achieve the objectives of this invention, the following technologies are proposed:

[0006] A flexible circuit board unloading temporary storage device includes:

[0007] The positioning unit is located on the positioning paper attached to the operating table of the laser cutting machine. It includes a first linear mechanism, a horizontal block on one side of its sliding end, and a second linear mechanism with a sliding direction perpendicular to the first linear mechanism on the horizontal block.

[0008] The pressing unit, located on one side of the positioning unit, is used to press the panel downwards when the flexible circuit board is removed;

[0009] The material handling unit is located on one side of the sliding end of the second linear mechanism. It includes a fourth linear mechanism whose output direction is parallel to the sliding direction of the first linear mechanism. A fifth linear mechanism is vertically provided at its output end. A rotary motor is provided at the lower end of the output shaft of the fifth linear mechanism. A three-way solenoid valve is provided at one end of its output shaft. Its two air inlets are respectively connected to rigid pipes. A vacuum suction cup is provided at one end of the rigid pipe. The material handling ends of the two vacuum suction cups are facing opposite directions.

[0010] The collection unit, located on one side of the material handling unit, includes a sixth linear mechanism whose output direction is perpendicular to the fourth linear mechanism, a seventh linear mechanism whose output direction is parallel to the sixth linear mechanism on one side of its output end, a C-shaped plate below the output end of the seventh linear mechanism, an eighth linear mechanism vertically fixed at the lower end of the seventh linear mechanism, and an L-shaped slider at the sliding end of the eighth linear mechanism.

[0011] The temporary storage cylinder is mounted on the upper side of the horizontal edge of the L-shaped slider. The upper end of the temporary storage cylinder is open, and the inner cavity is used to stack multiple flexible circuit boards in the vertical direction.

[0012] Furthermore, a horizontal plate is provided at the upper end of the sliding end of the first linear mechanism, a tray is provided at one end of the horizontal plate, and a counterweight is provided on the upper surface of the tray.

[0013] Furthermore, the pressing unit includes a vertically arranged third linear mechanism, with a side plate at the lower end of its output shaft. A plurality of vertical first pressing rods are provided on one side of the side plate, and a crossbar is provided at one end of the outer periphery of the first pressing rod, with a second pressing rod vertically provided at one end of the crossbar.

[0014] Furthermore, the third linear mechanism is vertically fixed to one side of the horizontal block.

[0015] Furthermore, the rigid tube includes a horizontal section and a bend connecting the two ends of the horizontal section, with a vacuum suction cup located at one end of a bend.

[0016] Furthermore, the upper end face of the horizontal edge of the L-shaped slider is provided with an insert block, and the bottom end face of the temporary storage cylinder is provided with a slot that matches the insert block.

[0017] Furthermore, a side door is provided on one end of the temporary storage cylinder, and a side cover plate is fitted at the side door.

[0018] Furthermore, T-shaped grooves are provided on both sides of the side door along the height direction, and the T-shaped grooves extend upward to the upper end of the temporary storage cylinder. A pair of T-shaped sliders that match the T-shaped grooves are provided on one side of the side cover plate.

[0019] Furthermore, the sliding end of the second linear mechanism is provided with a mounting plate, the fourth linear mechanism is fixed to the upper surface of the mounting plate, and the sixth linear mechanism is fixed to the lower surface of the mounting plate.

[0020] The beneficial effects of this technical solution are as follows:

[0021] 1. The pressing unit moves with the first linear mechanism of the positioning unit. When cutting each row of flexible circuit boards on the panel, the panel can be fixed, which facilitates the cutting of the flexible circuit boards.

[0022] 2. The material handling unit, collection unit, and temporary storage cylinder can move as a whole with the first and second linear mechanisms of the positioning unit, automatically and sequentially feeding and temporarily storing the flexible circuit boards, saving manpower.

[0023] 3. The rotary motor in the material handling unit allows for changing the orientation of the flexible circuit boards picked up by the vacuum suction cups, ensuring that all stacked flexible circuit boards face the same direction during temporary storage, facilitating subsequent use. Two vacuum suction cups are used, with a three-way solenoid valve ensuring that the lower suction cup is always used for picking up the boards. This eliminates the need to rotate a single vacuum suction cup downwards after the flexible circuit boards have been repositioned, further accelerating the work process. Attached Figure Description

[0035] like Figures 1-10 The flexible circuit board unloading and temporary storage device shown includes a positioning unit 1, a pressing unit 2, a picking unit 3, a collecting unit 4, and a temporary storage cylinder 5.

[0036] The positioning unit 1 is located on the positioning paper 6 attached to the operating table of the laser cutting machine. Specifically, before using the material storage device, a pair of positioning points 62 are first drawn on the upper surface of the positioning paper 6 so that the material storage device can be positioned accurately during operation, making it easy to take out and temporarily store the flexible circuit board 8. The positioning unit 1 includes a first linear mechanism 11, with its two ends respectively mounted on two supports 12. The lower end of the support 12 is provided with a base 13, and one end of the base 13 is provided with an inspection ring 14, the inner circumference of which matches the positioning points 62 respectively. The upper end of the sliding end of the first linear mechanism 11 is provided with a horizontal plate 15, and one end of the horizontal plate 15 is provided with a tray 16. The upper surface of the tray 16 is provided with a lead counterweight 17. One side of the sliding end of the first linear mechanism 11 is provided with a horizontal block 18 that is located above the splicing plate 7 during operation. The horizontal block 18 is provided with a second linear mechanism 19 whose sliding direction is perpendicular to the first linear mechanism 11, and its sliding end is provided with a mounting plate 191.

[0037] The pressing unit 2 is located on one side of the positioning unit 1 and is used to press the panel 7 downward when the flexible circuit board 8 is removed. It includes a third linear mechanism 21 that is vertically fixed to one side of the horizontal block 18. The lower end of its output shaft is provided with a base plate 22. One end of the base plate 22 is provided with a side plate 23. One side of the side plate 23 is provided with multiple connecting rods 24. One end of the connecting rod 24 is provided with a first pressing rod 25 vertically. One end of the outer periphery of the first pressing rod 25 is provided with a horizontal bar 26. One end of the horizontal bar 26 is provided with a second pressing rod 27 vertically. During operation, the bottom ends of each of the two adjacent first pressing rods 25 and the two second pressing rods 27 connected to them press against the four corners of the outer side of a flexible circuit board 8, which is the gap position between the flexible circuit boards 8 placed on the panel 7.

[0038] The material handling unit 3 is located at one end of the pressing unit 2. It includes a fourth linear mechanism 31 fixed to the upper surface of the mounting plate 191 and whose output direction is parallel to the sliding direction of the first linear mechanism 11. Its output end is provided with a vertical plate 32. A fifth linear mechanism 33 is vertically fixed to one end of the vertical plate 32. A rotary motor 34 is provided at the lower end of the output shaft of the fifth linear mechanism 33. The axis of its output shaft is parallel to the axis of the output shaft of the fourth linear mechanism 31. A three-way solenoid valve 35 is provided at one end of the output shaft of the rotary motor 34. Its air outlet 36 is used to connect to an external air extraction device, such as a vacuum pump. The two air inlets of the three-way solenoid valve 35 are respectively connected to rigid pipes 37. A vacuum suction cup 38 is provided at one end of the rigid pipe 37. In this embodiment, the rigid pipe 37 includes a horizontal section and a bent section connected to both ends of the horizontal section. A vacuum suction cup 38 is provided at one end of one bent section. The suction ends of the two vacuum suction cups 38 face opposite directions.

[0039] The collecting unit 4 is located on one side of the picking unit 3, including a sixth linear mechanism 41 fixed to the lower end face of the mounting plate 191 and whose output direction is perpendicular to the fourth linear mechanism 31. One end of its output shaft is provided with an inverted L-shaped hanging plate 42. The lower end of the vertical side of the inverted L-shaped hanging plate 42 is provided with a seventh linear mechanism 43 whose output direction is parallel to the sixth linear mechanism 41. One end of the output shaft of the seventh linear mechanism 43 is provided with a push plate 44. The lower end of the push plate 44 is provided with a C-shaped plate 45. The distance between the two parallel inner sides of the C-shaped plate 45 matches the distance from one end to the other of the flexible circuit board 8. The lower end of the seventh linear mechanism 43 is provided with a vertical seat 46. An eighth linear mechanism 47 is vertically fixed on one side of the vertical seat 46. The sliding end of the eighth linear mechanism 47 is provided with an L-shaped slider 48, and the upper end face of its horizontal side is provided with an insert block 49.

[0040] The temporary storage cylinder 5 is mounted on the upper end of the horizontal side of the L-shaped slider 48. The upper end of the temporary storage cylinder 5 is open. The inner cavity of the temporary storage cylinder 5 is used to stack multiple flexible circuit boards 8 in the vertical direction. One end face of the temporary storage cylinder 5 is provided with a side door. A side cover plate 52 is installed at the side door. T-shaped grooves 51 are opened on both sides of the side door along the height direction. The T-shaped grooves 51 extend upward to the upper end of the temporary storage cylinder 5. A pair of T-shaped sliders 53 are provided on one side of the side cover plate 52, which are respectively matched with the T-shaped grooves 51. A slot 54 matching the insert block 49 is opened on the bottom end face of the temporary storage cylinder 5.

[0041] In this embodiment, the first linear mechanism 11, the second linear mechanism 19, and the eighth linear mechanism 47 all use rodless linear cylinders, while the third linear mechanism 21, the fourth linear mechanism 31, the fifth linear mechanism 33, the sixth linear mechanism 41, and the seventh linear mechanism 43 all use single-axis linear cylinders.

[0042] Work style:

[0043] First, align the visual inspection ring 14 with the positioning point 62, place the entire flexible circuit board unloading temporary storage device on the positioning paper 6 after the cutting is completed, and then the staff can leave the site for a period of time.

[0044] Then, starting from one end of panel 7, each flexible circuit board 8 in each row is sequentially cut and temporarily stored.

[0045] Taking a single flexible circuit board 8 as an example, the first linear mechanism 11 moves the pressing unit 2, the picking unit 3, the collecting unit 4, and the temporary storage cylinder 5 to one end of the panel 7. The second linear mechanism 19 moves the picking unit 3, the collecting unit 4, and the temporary storage cylinder 5 to one side of the panel 7. Then, the third linear mechanism 21 presses down each of the first pressing rods 25 and each of the second pressing rods 27 to stabilize the panel 7. Then, the three-way solenoid valve 35 controls the vacuum suction cup 38 located below to perform a suction and lifting action. Through the descent and ascent of the fifth linear mechanism 33, a flexible circuit board 8 is detached from the panel 7. Then, the fourth linear mechanism 31 moves the flexible circuit board 8 a certain distance so that it will not be blocked by the pressing unit 2 in subsequent operations. If the orientation of the flexible circuit board 8 allows it to be directly placed into the temporary storage cylinder 5 from top to bottom, then the fifth linear mechanism continues to move the flexible circuit board 8. Mechanism 33 lifts the flexible circuit board 8, and then the sixth linear mechanism 41 pulls the inverted L-shaped hanging plate 42 and its lower components, so that the temporary storage cylinder 5 is positioned a short distance below the flexible circuit board 8. Then, the suction is canceled, and the flexible circuit board 8 falls into the temporary storage cylinder 5. If the orientation of the flexible circuit board 8 is reversed as described above, then the direction of the flexible circuit board 8 is first rotated by the rotary motor 34, so that the orientation of the flexible circuit board 8 is consistent with the orientation inside the temporary storage cylinder 5. Next, the temporary storage cylinder 5 is raised by the eighth linear mechanism 47, and then the flexible circuit board 8 is lowered a short distance by the fifth linear mechanism 33. Then, the C-shaped plate 45 is pushed out by the seventh linear mechanism 43, and then the flexible circuit board 8 is raised a short distance again. Then, the suction is canceled, and the C-shaped plate 45 is pulled by the seventh linear mechanism 43 to make the flexible circuit board 8 fall into the temporary storage cylinder 5.

[0046] Then, the material handling unit 3, the collection unit 4, and the temporary storage cylinder 5 are moved by the second linear mechanism 19, and the above operation is repeated so that the flexible circuit board 8 in this row can complete the unloading and temporary storage.

[0047] Then, the first linear mechanism 11 moves the pressing unit 2, the picking unit 3, the collecting unit 4, and the temporary storage cylinder 5 to complete the unloading and temporary storage of the other rows of flexible circuit boards 8.

[0048] After all the flexible circuit boards 8 have been cut and temporarily stored, the temporary storage cylinder 5 can be directly detached from the insert block 49 for subsequent use. When in use, the flexible circuit board 8 can be obtained by sliding out the side cover plate 52.

[0049] The above are only some of the embodiments listed in this application and are not intended to limit this application.
