Description

Technical Field

[0001] This utility model relates to the field of board loading machine technology, specifically to a starting height quick adjustment device and a board loading machine. Background Technology

[0002] During the circuit board manufacturing process, solder paste needs to be printed on the first side of the circuit board before being printed on the second side. Therefore, when the board loading machine is loading the board, it first puts the circuit boards without solder paste on both sides into the turnover basket. After the board loading machine loads the board and prints the first side, it puts the printed circuit board into the turnover basket and flips it over so that the second side of the circuit board can be printed. As a result, the height of the first circuit board after the turnover basket is flipped is different from the height of the first circuit board before the flip. The turnover basket cannot be used for the same board loading machine before and after the flip. Utility Model Content

[0003] The primary objective of this invention is to provide a device for quickly adjusting the starting height of the turnover basket, enabling the same loading machine to be used for both before and after the basket is flipped.

[0004] The second objective of this invention is to provide a board machine that employs the aforementioned rapid starting height adjustment device.

[0005] To achieve the aforementioned first objective, this utility model provides a rapid starting height adjustment device, comprising: a fixed bracket; a movable bracket, which is movable relative to the fixed bracket in the Z-axis direction; a first lifting distance sensor, which is disposed on the fixed bracket and extends along the Z-axis direction, and has a plurality of first sensing teeth arranged sequentially along the Z-axis direction; a first sensor, which is disposed on the movable bracket and opposite to the first lifting distance sensor to sense the first sensing teeth; the rapid starting height adjustment device further comprises: a second lifting distance sensor, which is disposed on the fixed bracket and extends along the Z-axis direction, and has a plurality of second sensing teeth arranged sequentially along the Z-axis direction; a second sensor, which is disposed on the movable bracket and opposite to the second lifting distance sensor to sense the second sensing teeth, and the position of the second sensor is higher than the position of the first sensor; in a first working state, the first sensor is working and the second sensor is not working; in a second working state, the second sensor is working and the first sensor is not working.

[0006] As can be seen from the above scheme, by setting two lifting gap sensors and two sensors with different heights, in the first working state, that is, when the conveyed circuit board is a circuit board without solder paste printed on both sides, the first sensor is activated to detect the position of the movable bracket relative to the fixed bracket. In the second working state, that is, when the conveyed circuit board is a circuit board with solder paste printed on one side and not printed on the other, the placement position of the first circuit board is different from that in the first working state due to the turnover basket flipping. By activating the second sensor, the different starting heights can be quickly adjusted. This can solve the problem of the different placement positions of the first circuit board before and after the turnover basket flipping, which makes it impossible to use the board loading machine universally.

[0007] A preferred embodiment is that the fixed bracket has an inlet for the turnover basket, and the first lifting distance sensor and the second lifting distance sensor are respectively arranged on opposite sides of the turnover basket inlet in the Y-axis direction; the first sensor and the first lifting distance sensor are arranged opposite to each other in the X-axis direction, and the second sensor and the second lifting distance sensor are arranged opposite to each other in the X-axis direction.

[0008] As can be seen, the turnover basket can enter the movable support from the turnover basket inlet to complete the loading of the turnover basket. The first lifting distance sensor and the second lifting distance sensor are located on both sides of the turnover basket inlet, which facilitates the rational use of space.

[0009] A preferred embodiment is that the first lifting distance sensor has at least two first mounting holes, which are spaced apart along the Z-axis. A first fixing member is provided in the first mounting hole, and the first lifting distance sensor is fixed to the fixed bracket by the first fixing member; and / or the second lifting distance sensor has at least two second mounting holes, which are spaced apart along the Z-axis. A second fixing member is provided in the second mounting hole, and the second lifting distance sensor is fixed to the fixed bracket by the second fixing member.

[0010] As can be seen, by setting multiple mounting holes spaced apart along the Z-axis, the stable connection between the corresponding lifting distance sensor and the fixed bracket is ensured, which perfectly solves the risk of displacement and collision when the platform rises, and further improves the stability of detection between the lifting distance sensor and the corresponding sensor.

[0011] To achieve the second objective mentioned above, this utility model provides a board mounting machine, including the aforementioned rapid starting height adjustment device.

[0012] In a preferred embodiment, the loading machine further includes a loading component and a support drive; the movable support is provided with a turnover basket placement position, the support drive is mounted on the fixed support and drives the movable support to move along the Z-axis direction, the loading component is mounted on the fixed support, and the loading component includes a loading drive and a push rod, the loading drive can drive the push rod to move along the X-axis direction toward the turnover basket placement position.

[0013] As can be seen, the support drive component is used to drive the movable support to move and drive the turnover basket and the circuit board in the turnover basket to move along the Z-axis. The feeding component is used to push the circuit board in the turnover basket out to complete the board loading process. The positions of each component are set reasonably and compactly, which improves the space utilization rate and ensures that the board loading machine can stably load the board.

[0014] A further option is that the board loading machine also includes a turnover basket, which is placed at the turnover basket placement position. The turnover basket is equipped with multiple circuit board receiving slots, which are arranged sequentially along the Z-axis direction. The push rod can extend into the circuit board receiving slot.

[0015] As can be seen, the turnover basket is equipped with multiple circuit board receiving slots for accommodating circuit boards. When loading the circuit board, a push rod is inserted into the circuit board receiving slot to push the circuit board out for loading. The structure is stable and highly reliable.

[0016] A further option is that the movable support includes a support body and a base, which together form a placement area for the turnover basket. A conveying component is provided on the base, which can drive the turnover basket to move along the X-axis.

[0017] It is evident that by setting a conveying component on the base, the turnover basket is ensured to move into position when it is conveyed from the first conveying platform to the movable support, avoiding interference with other components during operation. At the same time, after the circuit boards in the turnover basket are loaded, the conveying component can convey the empty turnover basket to the second conveying platform, realizing fully automated loading, reducing the labor intensity of workers, and eliminating potential quality problems.

[0018] In a preferred embodiment, the first spacing between each first sensing tooth on the first lifting spacing sensor is equal to the second spacing between each second sensing tooth on the second lifting spacing sensor; the distance between the positions of the second sensors and the spacing between the circuit board receiving slots are both equal to the first spacing.

[0019] It can be seen that the first and second gaps are equal to the gaps between the circuit board receiving slots, thus ensuring that each detection of the sensing tooth by the sensor corresponds exactly to the distance of moving one circuit board layer.

[0020] In a preferred embodiment, the loading machine further includes a first conveying platform, which is positioned opposite to the inlet of the turnover basket on the fixed support. The first conveying platform extends along the X-axis and conveys the turnover basket towards the inlet along the X-axis.

[0021] It can be seen that the first conveying platform is used to move the turnover basket full of circuit boards to the movable support, so that the circuit boards can be transported out one by one.

[0022] A further embodiment is that the loading machine also includes a second conveying platform, which is arranged parallel to and above the first conveying platform. The second conveying platform and the first conveying platform are located on the same side of the movable support, and the second conveying platform conveys along the X-axis in a direction away from the entrance of the turnover basket.

[0023] Therefore, the second conveyor platform is used to transport empty turnover baskets out. Attached Figure Description

It should also be understood that terms defined in general dictionaries should be interpreted as having the meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0037] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0038] See Figures 1 to 4 The loading machine includes a starting height quick adjustment device 1, a loading assembly 2, a support drive component 3, a turnover basket 4, a first conveying platform 5, and a second conveying platform 6.

[0039] The starting height quick adjustment device 1 includes a fixed bracket 11, a movable bracket 12, a first lifting distance sensor 13, a first sensor 14, a second lifting distance sensor 15, and a second sensor 16.

[0040] The fixed bracket 11 has a movable bracket mounting cavity 111. The movable bracket 12 is located in the movable bracket mounting cavity 111 and can move relative to the fixed bracket 11 in the Z-axis direction. The bracket driving component 3 is mounted on the fixed bracket 11 and drives the movable bracket 12 to move along the Z-axis direction. The movable bracket 12 has a turnover basket placement position 120. The turnover basket 4 is placed at the turnover basket placement position 120. The turnover basket 4 has multiple circuit board receiving slots 41, which are arranged sequentially along the Z-axis direction. The feeding assembly 2 is mounted on the fixed bracket 11 and includes a feeding driving component 21. Figure 7 (See diagram) and push rod 22. The feeding drive unit 21 can drive the push rod 22 to move along the X-axis towards the turnover basket placement position 120, and the push rod 22 can extend into the circuit board receiving slot 41. In this embodiment, the feeding drive unit 21 is a cylinder, and the bracket drive unit 3 is a motor.

[0041] See Figures 4 to 7 The first lifting distance sensor 13 is mounted on the fixed bracket 11 and extends along the Z-axis. The first lifting distance sensor 13 is provided with a plurality of first sensing teeth 131 arranged sequentially along the Z-axis. The first sensor 14 is mounted on the movable bracket 12 and is positioned opposite to the first lifting distance sensor 13 to sense the first sensing teeth 131.

[0042] The second lifting distance sensor 15 is mounted on the fixed bracket 11 and extends along the Z-axis. The second lifting distance sensor 15 has multiple second sensing teeth 151 arranged sequentially along the Z-axis. The second sensor 16 is mounted on the movable bracket 12 and positioned opposite the second lifting distance sensor 15 to sense the second sensing teeth 151. The position of the second sensor 16 is higher than that of the first sensor 14. In the first operating state, the first sensor 14 is active, and the second sensor 16 is inactive; in the second operating state, the second sensor 16 is active, and the first sensor 14 is inactive.

[0043] The first spacing between the first sensing teeth 131 on the first lifting spacing sensor 13 is equal to the second spacing between the second sensing teeth 151 on the second lifting spacing sensor 15. The distance between the positions of the second sensor 16 and the first sensors 14, as well as the spacing between the circuit board receiving slots 41, are all equal to the first spacing. Since both the first and second spacings are equal to the spacing between the circuit board receiving slots 41, this ensures that each sensing tooth detected by the sensor corresponds exactly to the distance of one circuit board layer being moved.

[0044] The fixed bracket 11 has a turnover basket inlet 112. The turnover basket 4 can enter the movable bracket 12 through the turnover basket inlet 112 to complete the loading of the turnover basket 4. The first lifting distance sensor 13 and the second lifting distance sensor 15 are respectively set on opposite sides of the turnover basket inlet 112 in the Y-axis direction. The first sensor 14 and the first lifting distance sensor 13 are set opposite to each other in the X-axis direction, and the second sensor 16 and the second lifting distance sensor 15 are set opposite to each other in the X-axis direction.

[0045] The first lifting distance sensor 13 has at least two first mounting holes 132, and each first mounting hole 132 is arranged at intervals along the Z-axis. A first fixing member (not shown) is provided in the first mounting hole 132, and the first lifting distance sensor 13 is fixed to the fixing bracket 11 by each first fixing member.

[0046] The second lifting distance sensor 15 has at least two second mounting holes 152, which are spaced apart along the Z-axis. A second fixing member (not shown) is disposed within each second mounting hole 152, and the second lifting distance sensor 15 is fixed to the fixing bracket 11 by the second fixing members. Preferably, in this embodiment, the number of the first mounting holes 132 and the second mounting holes 152 are both five.

[0047] By setting multiple mounting holes spaced apart along the Z-axis, a stable connection between the corresponding lifting distance sensor and the fixed bracket 11 is ensured, perfectly solving the risk of displacement and collision when the platform rises, and further improving the stability of detection between the lifting distance sensor and the corresponding sensor.

[0048] The first conveying platform 5 is positioned opposite the turnover basket inlet 112 on the fixed bracket 11. The first conveying platform 5 extends along the X-axis and conveys circuit boards 4 towards the turnover basket inlet 112. The first conveying platform 5 is used to transfer the turnover basket 4 filled with circuit boards to the movable bracket 12, facilitating the one-by-one conveying of the circuit boards. The second conveying platform 6 is positioned parallel to and above the first conveying platform 5, on the same side of the movable bracket 12. The second conveying platform 6 conveys circuit boards 4 away from the turnover basket inlet 112 along the X-axis and is used to convey empty turnover basket 4 out.

[0049] See Figure 3 and Figure 8The movable support 12 includes a support body 121 and a base 122, which together form a turnover basket placement position 120. A conveying component 123 is provided on the base 122, which can drive the turnover basket 4 to move along the X-axis. By providing the conveying component 123 on the base 122, it is easy to ensure that the turnover basket 4 moves into position when the first conveying platform 5 conveys the turnover basket 4 to the movable support 12, avoiding interference with other components during operation. At the same time, after the circuit boards in the turnover basket 4 are loaded, the conveying component 123 can convey the empty turnover basket 4 to the second conveying platform 6, realizing fully automated loading, reducing the labor intensity of workers, and eliminating potential quality problems. In this embodiment, the conveying component 123, the first conveying platform 5, and the second conveying platform 6 all use existing transmission components such as conveyor belts, and the specific structure will not be described in detail here.

[0050] The working process of the board loading machine will be described in detail below.

[0051] First, when solder paste needs to be printed on the first side of the circuit board, the first sensor 14 is powered on and the second sensor 16 is powered off. Then, the turnover basket 4 containing the unprinted circuit boards on both sides is placed on the first conveying platform 5. At this time, the movable bracket 12 is in the lowest position, and the inner surface of the base 122 is flush with the first conveying platform 5. The first conveying platform 5 conveys the turnover basket 4 to the movable bracket 12. The turnover basket 4 enters the turnover basket placement position 120 of the movable bracket 12 through the turnover basket inlet 112. Then, under the action of the conveying component 123 on the movable bracket 12, the turnover basket 4 is conveyed to the position.

[0052] Next, the bracket drive 3 drives the movable bracket 12 to move upward, and the movable bracket 12 drives the turnover basket 4 to move upward a preset distance. When the first sensor 14 detects the first first sensing tooth 131, the bracket drive 3 stops working. At this time, the push rod 22 of the feeding assembly 2 is set relative to the top circuit board in the X-axis direction.

[0053] Next, the feeding drive 21 of the feeding assembly 2 drives the push rod 22 to move along the negative X-axis, and the push rod 22 pushes the top layer of circuit board to the solder paste printing station.

[0054] Next, the bracket drive 3 drives the movable bracket 12 and moves the turnover basket 4 upward a preset distance. When the first sensor 14 detects the second first sensing tooth 131, the bracket drive 3 stops working. At this time, the push rod 22 of the feeding assembly 2 and the circuit board of the second layer are set relative to each other in the X-axis direction.

[0055] Next, the feeding drive 21 of the feeding assembly 2 drives the push rod 22 to move along the negative X-axis, and the push rod 22 pushes the second layer circuit board to the solder paste printing station.

[0056] The process continues in the above cycle until all the circuit boards in the turnover basket 4 have been transported out. Then, the bracket drive 3 drives the movable bracket 12 and moves the turnover basket 4 upward until the inner surface of the base 122 of the movable bracket 12 is flush with the second conveying platform 6. The conveying component 123 on the movable bracket 12 is activated and transports the turnover basket 4 to the second conveying platform 6. The second conveying platform 6 then transports the empty turnover basket 4 to the preset position.

[0057] When solder paste needs to be printed on the second side of the circuit board, the second sensor 16 is powered on and the first sensor 14 is powered off. Then, the turnover basket 4 containing the circuit board with one side unprinted is flipped and placed on the first conveying platform 5. The movable support 12 is at its lowest position at this time, and the inner surface of the base 122 is flush with the first conveying platform 5. The first conveying platform 5 conveys the turnover basket 4 to the movable support 12. The turnover basket 4 enters the turnover basket placement position 120 of the movable support 12 through the turnover basket inlet 112. Then, under the action of the conveying component 123 on the movable support 12, the turnover basket 4 is conveyed to the position.

[0058] Next, the bracket drive 3 drives the movable bracket 12 to move upward, and the movable bracket 12 drives the turnover basket 4 to move upward a preset distance. When the second sensor 16 detects the first second sensing tooth 151, the bracket drive 3 stops working. At this time, the push rod 22 of the feeding assembly 2 is set relative to the top circuit board in the X-axis direction.

[0059] Next, the steps of the feeding drive unit 21 driving the push rod 22 onto the plate and the steps of the conveying assembly 123 and the second conveying platform 6 conveying the empty turnover basket 4 are the same as the steps described above, and will not be repeated here.

[0060] As can be seen from the above, by setting two lifting gap sensors and two sensors with different heights, in the first working state, that is, when the conveyed circuit board is a circuit board without solder paste printed on both sides, the first sensor is activated to detect the position of the movable bracket relative to the fixed bracket. In the second working state, that is, when the conveyed circuit board is a circuit board with solder paste printed on one side and not printed on the other, the placement position of the first circuit board is different from that in the first working state due to the turnover basket flipping. By activating the second sensor, the different starting heights can be quickly adjusted. This can solve the problem of the different placement heights of the first circuit board before and after the turnover basket flipping, which makes it impossible to use the board loading machine universally.

[0061] Finally, it should be emphasized that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
