[0030] The present invention will be described in more detail below with reference to the drawings and embodiments.

[0031] The present invention discloses an automatic PCB thin plate inserting hanging basket device, in combination with Figures 1 to 14 as shown, which includes:

[0032] A hanging basket 1, having a bottom card slot 10 for inserting the PCB thin plate 100;

[0033] A vertical insertion mechanism 2, arranged above the hanging basket 1, for clamping the PCB thin plate 100 and driving the PCB thin plate 100 to move downward;

[0034] A front and rear alignment mechanism 3, arranged between the vertical insertion mechanism 2 and the hanging basket 1, and the front and rear alignment mechanism 3 is used to apply a thrust to the PCB thin plate 100 from the front and rear sides, so that the lower end edge of the PCB thin plate 100 is aligned with the bottom card slot 10.

[0035] In the above structure, the vertical insertion mechanism 2 is used to load the PCB thin plate 100, clamp the PCB thin plate 100 through mechanisms such as air jaws, and perform a lifting motion to move the PCB thin plate 100 downward. When the lower end of the PCB thin plate 100 passes through the front-back alignment mechanism 3, the front-back alignment mechanism 3 simultaneously applies a thrust to the PCB thin plate 100 from the front and back sides, and aligns the position of the PCB thin plate 100 near the lower end by applying a thrust until the lower end edge of the PCB thin plate 100 is aligned with the bottom card slot 10. As the vertical insertion mechanism 2 continues to move downward, the PCB thin plate 100 is inserted into the hanging basket 1 and snapped into the bottom card slot 10. Compared with the prior art, the utility model solves the problem of the insertion accuracy of the PCB thin plate, effectively avoids the occurrence of wrong insertion, bending, etc. of the PCB thin plate, and further improves the process quality of the automatic insertion of the PCB thin plate into the hanging basket.

[0036] Regarding the specific structure of the hanging basket 1, in this embodiment, in combination with Figures 9 to 14 As shown, the hanging basket 1 includes a frame body 11. On the left and right sides of the upper end of the frame body 11, hanging brackets 12 are respectively fixed. At the bottom of the frame body 11, a plurality of bottom support blocks 13 evenly distributed in the left-right direction are fixed. A plurality of the bottom card slots 10 evenly distributed in the front-back direction are formed on the bottom support blocks 13. In this embodiment, the PCB thin plate 100 is supported by a plurality of bottom support blocks 13 evenly distributed on the left and right. At the same time, batch insertion of the PCB thin plate 100 is realized by using a plurality of the bottom card slots 10 evenly distributed in the front and back.

[0037] In order to play a limiting role on the PCB thin plate 100 on the left and right sides, in this embodiment, on the relative sides of the lower ends of the two hanging brackets 12, lateral limiting blocks 14 are respectively fixed. On the relative sides of the two lateral limiting blocks 14, a plurality of lateral limiting grooves 140 are respectively formed. The lateral limiting grooves 140 correspond to the bottom card slots 10 one by one.

[0038] In combination with Figure 9 、 Figure 10 、 Figure 13 and Figure 14 As shown, in this embodiment, a plurality of Teflon wires 15 evenly distributed in the front-back direction are arranged in the frame body 11. The gaps between adjacent two Teflon wires 15 correspond to the bottom card slots 10 one by one. Among them, the space between adjacent two Teflon wires 15 provides an insertion space for the PCB thin plate 100.

[0039] Further, the Teflon wire 15 includes a baffle 150 bent in an S shape and an upper cross bar 151 extending in the left - right direction. A plurality of lower cross bars 152 extending in the front - rear direction and arranged side by side are fixed to the lower end of the frame 11. The upper end of the baffle 150 coaxially passes through the upper cross bar 151, and the left and right ends of the baffle 150 are respectively inserted into the left and right hanging brackets 12. The lower end of the baffle 150 vertically passes through the plurality of lower cross bars 152. In the above structure, the baffle 150 bent in an S shape is fixed within the frame 11 through the upper cross bar 151 and the plurality of lower cross bars 152. Compared with using a grid or other separation methods, in this embodiment, more hollow areas can be provided on the front and rear sides of the PCB thin plate, so that the front and rear sides of the PCB thin plate can more fully contact the chemical solution.

[0040] For the preferred structure of the vertical insertion mechanism 2, please refer to Figures 3 to 6 As shown, the vertical insertion mechanism 2 includes a vertical support plate 20. A vertical motion module 21 is provided on the front side of the vertical support plate 20. The moving end of the vertical motion module 21 is provided with upper end air claws 22 evenly distributed in the left - right direction. The upper end air claws 22 are used to clamp the upper edge of the PCB thin plate 100. In this embodiment, the vertical motion module 21 is a vertically installed motor linear motion module, which can drive the PCB thin plate 100 to move up and down straight and stably. The plurality of upper end air claws 22 are evenly distributed in the left - right direction and can stably clamp the PCB thin plate 100.

[0041] In this embodiment, in combination with Figures 3 to 5 As shown, the vertical insertion mechanism 2 includes vertical support frames 23 respectively arranged on the left and right sides of the vertical support plate 20. A plurality of lateral air claws 24 are evenly distributed on the opposite sides of the two vertical support frames 23. Rollers 240 are respectively provided on the two clamping heads of the lateral air claws 24. The PCB thin plate 100 can be inserted between the two rollers 240. The lateral air claws 24 are used to drive the two rollers 240 to approach each other and clamp the PCB thin plate 100, so that the two rollers 240 are in rolling cooperation with the PCB thin plate 100.

[0042] Further, the vertical insertion mechanism 2 includes a vertical support frame driving mechanism for driving the two vertical support frames 23 to approach or move away from each other relatively.

[0043] In the above structure, when multiple upper air grippers 22 grip the PCB thin plate 100, the vertical support driving mechanism can be used to drive the vertical support 23 close to the side of the PCB thin plate 100, so that the edge of the PCB thin plate 100 enters between two symmetric rollers 240. Then, the lateral air gripper 24 drives the two rollers 240 to approach each other and grip the PCB thin plate 100. The two rollers 240 maintain a rolling cooperation relationship with the PCB thin plate 100. When the vertical movement module 21 drives the PCB thin plate 100 to move downward, with the cooperation of multiple groups of rollers 240, it is ensured that the PCB thin plate 100 descends straight, effectively preventing the PCB thin plate 100 from being bent and deformed.

[0044] Please refer to Figure 6 , an upper back plate 25 and a lower back plate 26 are embedded in the middle of the vertical support plate 20, and an upper driving cylinder 27 and a lower driving cylinder 28 for driving the upper back plate 25 and the lower back plate 26 to move back and forth are fixedly arranged on the vertical support plate 20.

[0045] Regarding the preferred matching method of the upper back plate 25 and the lower back plate 26, in this embodiment, a lower notch 250 is formed at the lower end of the upper back plate 25, and an upper convex block 260 is formed at the upper end of the lower back plate 26. The upper convex block 260 can be embedded in the lower notch 250 and the two are movably matched.

[0046] In the above structure, before the lateral air grippers 24 on both sides are ready to grip the PCB thin plate 100, the upper driving cylinder 27 and the lower driving cylinder 28 first drive the upper back plate 25 and the lower back plate 26 to move forward, so that the upper back plate 25 and the lower back plate 26 abut against the back of the PCB thin plate 100, keeping the PCB thin plate 100 flat. Then, the vertical support driving mechanism is controlled to drive the vertical support 23 close to the side of the PCB thin plate 100. In this state, when the lateral air gripper 24 drives the two rollers 240 to approach each other and grip the PCB thin plate 100, it can still ensure that the plate body of the PCB thin plate 100 is flat, avoiding adverse situations such as uneven stress and plate body deformation of the PCB thin plate 100 during the process of gripping the side.

[0047] To further ensure the accurate insertion of the PCB thin plate 100, in combination with Figure 7 and Figure 8As shown in the figure, the front and back alignment mechanism 3 includes two alignment components 30. Each alignment component 30 includes an alignment bracket 300, a lifting cylinder 301 fixedly installed on the alignment bracket 300, a front and back movement cylinder 302 fixedly installed on the moving end of the lifting cylinder 301, and an alignment push plate 303 fixedly installed on the moving end of the front and back movement cylinder 302. The alignment push plates 303 in the two alignment components 30 are aligned front and back, and the two alignment push plates 303 are respectively used to abut against the front and back sides of the PCB thin plate 100. In practical applications, when the vertical insertion mechanism 2 drives the PCB thin plate 100 to descend to the upper end of the hanging basket 1 and is ready for insertion, the two front and back movement cylinders 302 drive the two alignment push plates 303 to clamp the PCB thin plate 100 from the front and back sides respectively, so that the PCB thin plate 100 is kept flat. Then, the lifting cylinder 301 descends together with the vertical insertion mechanism 2, so that the PCB thin plate 100 is kept in a position aligned with the lateral limiting groove 140 and the bottom card slot 10, thereby improving the insertion accuracy of the PCB thin plate 100 in sequence.

[0048] In order to avoid large friction with the PCB thin plate 100, in this embodiment, a plurality of vertical blocking strips 304 are respectively fixedly installed on the relative sides of the two alignment push plates 303, and an oblique transition portion 305 is formed at the upper end of the vertical blocking strip 304.

[0049] As a preferred method, in combination with Figure 7 , Figure 8 and Figure 12 As shown in the figure, transverse blocking strips 306 extending in the left-right direction are respectively fixedly installed on the relative sides of the two alignment push plates 303. The transverse blocking strips 306 are arranged below the plurality of vertical blocking strips 304, and a wedge-shaped chuck 307 is formed at the lower end of the transverse blocking strip 306. The wedge-shaped chucks 307 on the two alignment push plates 303 are used to clamp the lower end of the PCB thin plate 100 and align it with the two relatively lateral limiting grooves 140. The lifting cylinder 301 drives the two wedge-shaped chucks 307 to clamp the PCB thin plate 100 and descend into the lateral limiting groove 140.

[0050] In the above structure, the wedge-shaped chucks 307 are respectively arranged at the lower ends of the two positive pushing plates 303. On the basis of clamping the PCB thin plate 100, the two wedge-shaped chucks 307 can also, driven by the lifting motion cylinder 301, correct the lower edge of the PCB thin plate 100 and then enter the relatively opposed lateral limiting grooves 140 on both sides together. When the PCB thin plate 100 is accurately inserted and continues to descend to the bottom card slot 10, the two positive pushing plates 303 are controlled to rise and separate from each other, thereby realizing the functions of straightening and auxiliary alignment of the PCB thin plate 100, and at the same time improving the accuracy and reliability of the automatic insertion of the PCB thin plate.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the technical scope of the present invention shall be included within the scope protected by the present invention.
