Description

Technical Field

[0001] This utility model belongs to the field of PCB board manufacturing technology, and in particular relates to a material hopper structure and laser drilling equipment. Background Technology

[0002] In existing technologies, when loading PCBs (Printed Circuit Boards) into laser drilling equipment, a robotic arm typically places the stacked PCBs from the hopper onto the machine platform one by one. However, due to the buffering effect of air gaps between adjacent PCBs (similar to air flotation) or static electricity between layers, the robotic arm often uses an up-and-down shaking motion to shake the stuck PCBs into the hopper. The PCBs that fall into the hopper are prone to deviating from their original stacking position, resulting in lower stability of subsequent board handling. Utility Model Content

[0003] The technical problem to be solved by this utility model is: to address the technical problem that PCB boards shaken into the hopper will deviate from their original stacking position in the prior art, and to provide a hopper structure and laser drilling equipment.

[0004] To address the aforementioned technical problems, this utility model provides a hopper structure, including a support plate, a first limiting frame, a second limiting frame, a first limiting component, and a second limiting component. The support plate supports a PCB board. The first limiting frame and the second limiting frame are mounted on the same side of the support plate along a first direction. The first limiting component is movably connected to the second limiting frame along a second direction. The first limiting component includes a first limiting member and a first locking device. The first locking device is connected to the first limiting member. The first locking device has a first locking state capable of locking the first limiting member to the second limiting frame and a first unlocking state capable of unlocking the first limiting member and allowing it to move relative to the second limiting frame along the second direction. The second limiting component is movably connected to the first limiting frame along the third direction; the second limiting component includes a second limiting member and a second locking device, the second locking device is connected to the second limiting member, the second locking device has a second locking state capable of locking the second limiting member to the first limiting frame, and a second unlocking state capable of unlocking the second limiting member and moving it relative to the first limiting frame along the third direction.

[0005] According to the hopper structure of this utility model embodiment, a first limiting component, consisting of a first limiting member and a first locking device, is movably connected to a second limiting frame along a second direction. By switching the state of the first locking device, the first limiting member can be locked to the second limiting frame or can move relative to the second limiting frame along the second direction to adjust the distance between the first limiting member and the first limiting frame to adapt to the width of the PCB board. At the same time, a second limiting component, consisting of a second limiting member and a second locking device, is movably connected to the first limiting frame along a third direction. By switching the state of the second locking device, the second limiting member can be locked to the first limiting frame or can move relative to the first limiting frame along a third direction to adjust the distance between the second limiting member and the second limiting frame to adapt to the length of the PCB board. Therefore, the hopper structure, through the cooperation of the first limiting component, the second limiting component, the first limiting frame and the second limiting frame, forms a stacking space that can adapt to different lengths and / or widths. This stacking space can restrict the stacking position of PCB boards, reduce the possibility of positional deviation when the PCB boards are shaken into the hopper structure, and improve the positional accuracy of subsequent board grabbing.

In the second locking state, the second clamping member is in the second clamping position; in the second unlocking state, the second clamping member is away from the second clamping position.

[0025] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] like Figures 1 to 9 As shown, the hopper structure 100 provided in this embodiment of the present invention includes a support plate 1, a first limiting frame 2, a second limiting frame 3, a first limiting component, and a second limiting component. The support plate 1 is used to support the PCB board 200. The first limiting frame 2 and the second limiting frame 3 are installed on the same side of the support plate 1 along a first direction z. The first limiting component is movably connected to the second limiting frame 3 along a second direction x. The first limiting component includes a first limiting member 4 and a first locking device 5. The first locking device 5 is connected to the first limiting member 4. The first locking device 5 has a first locking state that can lock the first limiting member 4 to the second limiting frame 3, and a first unlocking state that can unlock the first limiting member 4 and allow it to move relative to the second limiting frame 3 along the second direction x.

[0027] The second limiting component is movably connected to the first limiting frame 2 along a third direction y. The second limiting component includes a second limiting member 6 and a second locking device 7. The second locking device 7 is connected to the second limiting member 6 and has a second locking state capable of locking the second limiting member 6 to the first limiting frame 2, and a second unlocking state capable of unlocking the second limiting member 6 and allowing it to move relative to the first limiting frame 2 along a third direction y.

[0028] The first direction z, the second direction x, and the third direction y are all perpendicular to each other.

[0029] The hopper structure 100 provided in this embodiment of the utility model includes a first limiting component consisting of a first limiting member 4 and a first locking device 5, which is movably connected to a second limiting frame 3. By switching the state of the first locking device 5, the first limiting member 4 can be locked to the second limiting frame 3 or can move relative to the second limiting frame 3 along the second direction x, so as to adjust the distance between the first limiting member 4 and the first limiting frame 2 to adapt to the width of the PCB board 200. At the same time, the second limiting component consisting of a second limiting member 6 and a second locking device 7 is movably connected to the first limiting frame 2 along the third direction y. By switching the state of the second locking device 7, the second limiting member 6 can be locked to the first limiting frame 2 or can move relative to the first limiting frame 2 along the third direction y, so as to adjust the distance between the second limiting member 6 and the second limiting frame 3 to adapt to the length of the PCB board 200. Thus, the hopper structure 100, through the cooperation of the first limiting member 4, the second limiting member 6, the first limiting frame 2 and the second limiting frame 3, forms a stacking space that can adapt to different lengths and / or widths. This stacking space can restrict the stacking position of the PCB board 200, reduce the possibility of positional deviation when the PCB board 200 is shaken into the hopper structure 100, and improve the positional accuracy of subsequent board grabbing.

[0030] In one embodiment, such as Figures 4 to 8 As shown, the first locking device 5 includes a first base 51, a first clamping member 52, and a first locking assembly 53. The first clamping member 52 is rotatably connected to the first base 51. The first clamping member 52 is provided with a first clamping position. When the first clamping member 52 is in the first clamping position (refer to...), Figures 4 to 6 The first clamping member 52 can cooperate with the first base 51 to clamp the second limiting frame 3 along the third direction y.

[0031] like Figures 4 to 6 As shown, in the first locking state, the first clamping member 52 is in the first clamping position. Figures 7 to 8 As shown, in the first unlocked state, the first clamping member 52 is away from the first clamping position.

[0032] The first locking assembly 53 is used to temporarily fix the first clamping member 52 in the first clamping position when in the first locked state. The first limiting member 4 is installed on the first base 51.

[0033] When the first limiting member 4 is locked to the second limiting frame 3, the first clamping member 52 can be rotated to the first clamping position. At this time, the first clamping member 52 can cooperate with the first base 51 to clamp the second limiting frame 3 along the third direction y. The first locking device 5 switches to the first locking state, so that the first locking device 5 is temporarily fixed to the second limiting frame 3, thereby temporarily fixing the position of the first limiting member 4 and realizing the locking of the first limiting member 4 by the first locking device 5.

[0034] When the position of the first limiting member 4 needs to be adjusted, the first clamping member 52 can be rotated and moved away from the first clamping position. The first clamping member 52 and the first base 51 release the clamping of the second limiting frame 3. The first locking device 5 switches to the first unlocking state, so that the first locking device 5 and the first limiting member 4 can move relative to the second limiting frame 3 along the second direction x until the first limiting member 4 abuts against the edge of the PCB board 200 placed on the carrier plate 1, thus completing the position adjustment of the first limiting member 4.

[0035] In one embodiment, such as Figures 4 to 8 As shown, the first base 51 includes a first substrate 511, a second substrate 512 and a third substrate 513. The first substrate 511 and the second substrate 512 are disposed opposite each other along the second direction x, and the first substrate 511 is closer to the first limiting frame 2 along the second direction x relative to the second substrate 512. The third substrate 513 connects the first substrate 511 and the second substrate 512. The first clamping member 52 is rotatably connected between the first substrate 511 and the second substrate 512. The first locking component 53 is installed on the third substrate 513.

[0036] The first limiting member 4 is mounted on the first substrate 511.

[0037] The third substrate 513 is connected between the first substrate 511 and the second substrate 512. At this time, the cross section of the first base 51 perpendicular to the first direction z can be in the shape of a "U". The first substrate 511 and the second substrate 512 are located on the side of the third substrate 513 facing away from the second limiting frame 3 along the third direction y.

[0038] By rotatably connecting the first clamping member 52 between the first substrate 511 and the second substrate 512, installing the first locking component 53 on the third substrate 513, and installing the first limiting member 4 on the first substrate 511, the installation of the first clamping member 52, the first locking component 53 and the first limiting member 4 on the first base 51 can be realized respectively.

[0039] In other embodiments not shown in the figure, since the second substrate is further away from the first limiting frame and the side of the second substrate is not used for limiting the PCB board, the setting of the second substrate can be eliminated, that is, the first base is composed only of the first substrate and the third substrate.

[0040] In one embodiment, such as Figures 4 to 8 As shown, the first locking device 5 also includes a first rotating shaft 54, with the two ends of the first rotating shaft 54 ​​connected to the first base plate 511 and the second base plate 512 respectively. The first clamping member 52 is rotatably connected to the first rotating shaft 54, thereby realizing the rotatable connection of the first clamping member 52 on the first base 51.

[0041] In one embodiment, such as Figures 4 to 8 As shown, the first clamping member 52 includes a first clamping part 521, a first connecting part 522 and a first locking part 523. The first connecting part 522 connects the first clamping part 521 and the first locking part 523. The first connecting part 522 is rotatably connected to the first base 51. The first locking part 523 can abut against the first locking component 53, so that the first clamping member 52 can be temporarily fixed in the first clamping position.

[0042] When the first clamping member 52 is in the first clamping position, the first clamping part 521 is opposite to the first base 51 along the third direction y, and the first clamping part 521 can form a first clamping gap with the first base 51 for clamping the second limiting frame 3.

[0043] When the first clamping member 52 is in the first clamping position, the first clamping part 521 can cooperate with the first base 51 to clamp the second limiting frame 3 in the first clamping gap, thereby achieving temporary fixation of the first locking device 5 and the first limiting member 4.

[0044] In one embodiment, such as Figures 4 to 8 As shown, the first clamping member 52 also includes a first gasket 524, which is mounted on the side of the first clamping part 521 facing the first base 51.

[0045] The first gasket 524 can be made of an elastic material, such as plastic, to reduce friction between the first clamping member 52 and the second limiting frame 3.

[0046] When the first clamping member 52 is in the first clamping position, the first pad 524 will abut against the second limiting frame 3 to fix the first locking device 5 to the second limiting frame 3.

[0047] In one embodiment, such as Figures 4 to 8 As shown, the first locking assembly 53 includes a first locking frame 531, a first connecting rod 532, a second connecting rod 533, and a third connecting rod 534. The first locking frame 531 is mounted on the first base 51. The middle part of the first connecting rod 532 is rotatably connected to the first locking frame 531. One end of the first connecting rod 532 is rotatably connected to one end of the second connecting rod 533. The other end of the second connecting rod 533 is rotatably connected to one end of the third connecting rod 534. The third connecting rod 534 is slidably connected to the first locking frame 531 along the first direction z.

[0048] When the first clamping member 52 is in the first clamping position, the other end of the third link 534 can abut against the first locking part 523.

[0049] By swinging the first link 532, the third link 534 can slide relative to the first locking frame 531 along the first direction z through the linkage between the first link 532, the second link 533, and the third link 534. In the first locked state, the first locking frame 531 can be brought close to and abut against the first locking part 523, so that the first locking assembly 53 can abut against the first locking part 523, and the first clamping member 52 can be temporarily fixed in the first clamping position. When it is necessary to adjust the position of the first limiting member 4, the first locking frame 531 can be moved away from the first locking part 523 to release the abutment with the first locking part 523. At this time, the first clamping member 52 can rotate relative to the first base 51, releasing the clamping of the second limiting frame 3.

[0050] In an embodiment not shown in the figure, a sliding fit structure can also be provided between the other end of the third link and the first locking part. For example, a groove can be provided on the first locking part, and the extension direction of the groove is perpendicular to the extension direction of the first rotating shaft. The other end of the third link is slidably fitted with the groove. At this time, the other end of the third link can be driven to slide relative to the groove by the movement of the third link along the first direction z. Since the first clamping member and the first base are rotatably connected, the first clamping member can be driven to rotate during the sliding process, which can save the time of manually rotating the first clamping member.

[0051] In one embodiment, such as Figures 4 to 8 As shown, the first locking assembly 53 also includes a first handle 535, which is mounted on the other end of the first connecting rod 532.

[0052] The first handle 535 is designed to facilitate the swinging of the first link 532.

[0053] In one embodiment, such as Figures 1 to 3 , Figure 9 As shown, the structure of the second locking device 7 is basically the same as that of the first locking device 5. The second locking device 7 includes a second base 71, a second clamping member 72 and a second locking assembly 73. The second clamping member 72 is rotatably connected to the second base 71. The second clamping member 72 is provided with a second clamping position. When the second clamping member 72 is in the second clamping position, the second clamping member 72 can cooperate with the second base 71 to clamp the first limiting frame 2 along the second direction x.

[0054] In the second locked state, the second clamping member 72 is in the second clamping position. In the second unlocked state, the second clamping member 72 is away from the second clamping position.

[0055] The second locking assembly 73 is used to temporarily fix the second clamping member 72 in the second clamping position when in the second locked state. The second limiting member 6 is installed on the second base 71.

[0056] When the second limiting member 6 is locked to the first limiting frame 2, the second clamping member 72 can be rotated to the second clamping position. At this time, the second clamping member 72 can cooperate with the second base 71 to clamp the first limiting frame 2 along the second direction x. The second locking device 7 switches to the second locking state, so that the second locking device 7 is temporarily fixed to the first limiting frame 2, thereby temporarily fixing the position of the second limiting member 6 and realizing the locking of the second limiting member 6 by the second locking device 7.

[0057] When the position of the second limiting member 6 needs to be adjusted, the second clamping member 72 can be rotated and moved away from the second clamping position. The second clamping member 72 and the second base 71 release the clamping of the first limiting frame 2. The second locking device 7 switches to the second unlocking state, so that the second locking device 7 and the second limiting member 6 can move relative to the first limiting frame 2 along the second direction x until the second limiting member 6 abuts against the edge of the PCB board 200 placed on the carrier plate 1, thus completing the position adjustment of the second limiting member 6.

[0058] In one embodiment, such as Figures 1 to 3 , Figure 9 As shown, the second base 71 includes a fourth substrate, a fifth substrate, and a sixth substrate. The fourth substrate and the fifth substrate are arranged opposite each other along a third direction y, and the fourth substrate is closer to the second limiting frame 3 along the third direction y than the fifth substrate. The sixth substrate connects the fourth substrate and the fifth substrate. The second clamping member 72 is rotatably connected between the fourth substrate and the fifth substrate. The second locking component 73 is installed on the sixth substrate.

[0059] The second limiting member 6 is mounted on the fourth substrate.

[0060] The sixth substrate is connected between the fourth substrate and the fifth substrate. At this time, the cross section of the second base 71 perpendicular to the first direction z can be in the shape of a "U". The fourth substrate and the fifth substrate are located on the side of the sixth substrate facing away from the first limiting frame 2 along the second direction x.

[0061] By rotatably connecting the second clamping member 72 between the fourth substrate and the fifth substrate, mounting the second locking component 73 on the sixth substrate, and mounting the second limiting member 6 on the fourth substrate, the second clamping member 72, the second locking component 73, and the second limiting member 6 are respectively installed on the second base 71.

[0062] In other embodiments not shown in the figure, since the fifth substrate is further away from the second limiting frame and the fifth substrate side is not used for limiting the PCB board, the fifth substrate can be omitted, that is, the second base is composed only of the fourth substrate and the sixth substrate.

[0063] In one embodiment, such as Figures 1 to 3 , Figure 9 As shown, the second locking device 7 also includes a second rotating shaft 74, with the two ends of the second rotating shaft 74 connected to the fourth substrate and the fifth substrate respectively. The second clamping member 72 is rotatably connected to the second rotating shaft 74, thereby realizing the rotatable connection of the second clamping member 72 on the second base 71.

[0064] In one embodiment, such as Figures 1 to 3 , Figure 9 As shown, the second clamping member 72 includes a second clamping part, a second connecting part, and a second locking part. The second connecting part connects the second clamping part and the second locking part. The second connecting part is rotatably connected to the second base 71. The second locking part can abut against the second locking assembly 73, so that the second clamping member 72 can be temporarily fixed in the second clamping position.

[0065] When the second clamping member 72 is in the second clamping position, the second clamping part is opposite to the second base 71 along the second direction x, and the second clamping part can form a second clamping gap with the second base 71 for clamping the first limiting frame 2.

[0066] When the second clamping member 72 is in the second clamping position, the second clamping part can cooperate with the second base 71 to clamp the first limiting frame 2 in the second clamping gap, thereby achieving temporary fixation of the second locking device 7 and the second limiting member 6.

[0067] In one embodiment, such as Figures 1 to 3 , Figure 9 As shown, the second clamping member 72 also includes a second gasket, which is installed on the side of the second clamping part facing the second base 71.

[0068] The second gasket can be made of an elastic material, such as plastic, to reduce friction between the second clamping member 72 and the first limiting frame 2.

[0069] When the second clamping member 72 is in the second clamping position, the second pad will abut against the first limiting frame 2 to fix the second locking device 7 to the first limiting frame 2.

[0070] In one embodiment, such as Figures 1 to 3 , Figure 9 As shown, the second locking assembly 73 includes a second locking frame, a fourth link, a fifth link, and a sixth link. The second locking frame is mounted on the second base 71. The middle part of the fourth link is rotatably connected to the second locking frame. One end of the fourth link is rotatably connected to one end of the fifth link. The other end of the fifth link is rotatably connected to one end of the sixth link. The sixth link is slidably connected to the second locking frame along the first direction z.

[0071] When the second clamping member 72 is in the second clamping position, the other end of the sixth link can abut against the second locking part.

[0072] By swinging the fourth link, the sixth link can slide relative to the second locking frame along the first direction z through the linkage between the fourth, fifth, and sixth links. In the second locked state, the second locking frame can be brought close to and abut against the second locking part, allowing the second locking assembly 73 to engage with the second locking part, and the second clamping member 72 to be temporarily fixed in the second clamping position. When it is necessary to adjust the position of the second limiting member 6, the second locking frame can be moved away from the second locking part to release the contact with the second locking part. At this time, the second clamping member 72 can rotate relative to the second base 71, releasing the clamping of the first limiting frame 2.

[0073] In an embodiment not shown in the figure, a sliding fit structure can also be provided between the other end of the sixth link and the second locking part. For example, a groove can be provided on the second locking part, and the extension direction of the groove is perpendicular to the extension direction of the second rotating shaft. The other end of the sixth link is slidably fitted with the groove. At this time, the movement of the sixth link along the first direction z can drive the other end of the sixth link to slide relative to the groove. Since the second clamping member and the second base are rotatably connected, the second clamping member can be driven to rotate during the sliding process, which can save the time of manually rotating the second clamping member.

[0074] In one embodiment, such as Figures 1 to 3 , Figure 9 As shown, the second locking assembly 73 also includes a second handle, which is mounted on the other end of the fourth link.

[0075] The second handle facilitates the swinging of the fourth link.

[0076] In one embodiment, such as Figures 1 to 3 As shown, the hopper structure 100 also includes a third limiting frame 8 and a fourth limiting frame 9. The third limiting frame 8 is connected to the first limiting frame 2, and the second limiting member 6 is located between the second limiting frame 3 and the third limiting frame 8 along the third direction y.

[0077] The fourth limiting frame 9 is connected to the second limiting frame 3, and the first limiting member 4 is located between the first limiting frame 2 and the fourth limiting frame 9 along the second direction x.

[0078] The first limiting frame 2, the second limiting frame 3, the third limiting frame 8, and the fourth limiting frame 9 will form the maximum accommodating space of the PCB board 200. At the same time, since the third limiting frame 8 is connected to the first limiting frame 2, and the second limiting member 6 is located between the second limiting frame 3 and the third limiting frame 8 along the third direction y, the movement stroke of the second limiting member 6 can be limited by the third limiting frame 8; the fourth limiting frame 9 is connected to the second limiting frame 3, and the first limiting member 4 is located between the first limiting frame 2 and the fourth limiting frame 9 along the second direction x, the movement stroke of the first limiting member 4 can be limited by the fourth limiting frame 9.

[0079] On the other hand, this utility model embodiment provides a laser drilling device, which includes a machine base, a drilling device and the aforementioned hopper structure 100. The drilling device is mounted on the machine base, and the hopper structure 100 is used to provide the PCB board 200 to the drilling device. The drilling device is used to drill holes in the PCB board 200.

[0080] The laser drilling equipment provided in this embodiment of the utility model has a hopper structure 100 in which a first limiting member 4 and a first limiting frame 2 are arranged opposite each other along a second direction x. By switching the state of the first locking device 5, the first limiting member 4 can be locked to the second limiting frame 3 or can move relative to the second limiting frame 3 along the second direction x, so as to adjust the distance between the first limiting member 4 and the first limiting frame 2 to adapt to the width of the PCB board 200. At the same time, the second limiting member 6 and the second limiting frame 3 are arranged opposite each other along a third direction y. By switching the state of the second locking device 7, the second limiting member 6 can be locked to the first limiting frame 2 or can move relative to the first limiting frame 2 along the third direction y, so as to adjust the distance between the second limiting member 6 and the second limiting frame 3 to adapt to the length of the PCB board 200. Thus, the hopper structure 100, through the cooperation of the first limiting member 4, the second limiting member 6, the first limiting frame 2 and the second limiting frame 3, forms a stacking space that can adapt to different lengths and / or widths. This stacking space can restrict the stacking position of the PCB board 200, reduce the possibility of positional deviation when the PCB board 200 is shaken into the hopper structure 100, and improve the positional accuracy of subsequent board grabbing.

[0081] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
