Mounting device

Abstract

The application provides a mounting device, which comprises a shell and two parallel guide rails arranged in the shell. The mounting device further comprises at least two mounting clamps, which are arranged on the two guide rails in parallel along the width direction of the guide rails. Each mounting clamp has a first side perpendicular to the running direction of the guide rails, and the length of the first side is smaller than the width of the guide rails. The length of the first side of the mounting clamp is smaller than the width of the guide rails, so that the two mounting clamps can be arranged on the two guide rails in parallel along the width direction of the guide rails. When one mounting clamp is arranged on one guide rail, the mounting clamp does not extend into the adjacent guide rail, thereby preventing the problem of color difference of a circuit board caused by simultaneous mounting of two areas on the circuit board by two different mounting modules.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mounting equipment, in particular to a mounting device. BACKGROUND

[0002] With the development of science and technology, electronic technology is becoming more and more mature, and the application of circuit boards is becoming more and more common.

[0003] In the field of display screens, it is often necessary to mount lamp beads on circuit boards to form a light-emitting LED module. The conventional circuit board usually uses a mounting head to grab lamp beads or electronic components and mount the lamp beads or electronic components on the circuit board. Since the lamp beads or electronic components are far away from the parts to be mounted on the circuit board, when a single module clamp is used to grab the circuit board, the mounting head needs to move a long distance after grabbing the lamp beads or electronic components to mount the lamp beads and electronic components, which greatly affects the mounting efficiency.

[0004] Therefore, in order to improve the mounting efficiency, the existing scheme sets the mounting machine as a double-rail clamp to simultaneously grab the circuit board, thereby increasing the efficiency. However, due to the size limitation of the mounting machine and the clamp, when one clamp is placed on one rail, the clamp will extend into the adjacent rail, thereby causing the double modules to separately mount the areas on both sides of the center line of the circuit board, resulting in color difference in different areas of a single circuit board. SUMMARY

[0005] Therefore, it is necessary to provide a mounting device capable of preventing color difference in different areas of a single circuit board to solve the above problems.

[0006] Embodiments of the present application provide a mounting device, which comprises a housing and two rails arranged side by side in the housing, and further comprises:

[0007] at least two mounting clamps, which are arranged side by side on the two rails along the width direction of the rails;

[0008] wherein each mounting clamp has a first side perpendicular to the running direction of the rails, and the length of the first side is less than the width of the rails.

[0009] In at least one embodiment of the present application, the length of the first side ranges from 50mm to 250mm.

[0010] In at least one embodiment of the present application, the length of the first side is 247.5mm.

[0011] In at least one embodiment of this application, each mounting fixture has a second side parallel to the running direction of the guide rail, the length of which ranges from 306mm to 380mm.

[0012] In at least one embodiment of this application, the length of the second side is 360 mm.

[0013] In at least one embodiment of this application, the mounting device further includes a clamping member;

[0014] The mounting fixture includes a clamping part and a supporting part arranged around the clamping part;

[0015] The clamping member is located at the clamping part and is used to clamp the circuit board to the clamping part.

[0016] In at least one embodiment of this application, along the width direction of the guide rail, the support portion has a first region located at both ends of the clamping portion, the first region being used to support the guide rail.

[0017] In at least one embodiment of this application, the mounting device further includes an anti-arching component;

[0018] The anti-arching component is located in the first area and is used to fix the circuit board.

[0019] In at least one embodiment of this application, the width of the first region is 70 mm along the width direction of the guide rail.

[0020] In at least one embodiment of this application, the first region is provided with a plurality of heat dissipation holes for heat dissipation.

[0021] Beneficial effects: This application makes the first side of the mounting fixture smaller than the width of the guide rail, so that two mounting fixtures can be placed side by side on the two guide rails along the width direction of the guide rail. When one mounting fixture is placed on one guide rail, the mounting fixture will not extend into the adjacent guide rail, thereby preventing the problem of color difference on the circuit board caused by two different mounting modules mounting two areas on a circuit board at the same time.

[0030] Some embodiments of the present application will be described in detail with reference to the drawings. The following embodiments and features of the embodiments can be combined with each other without conflict.

[0031] Referring to Figure 1 and Figure 2 , the present application provides a mounting device 100 for mounting lamp beads or other electronic components on a circuit board 200. Specifically, the mounting device 100 includes a housing (not shown), two guide rails 10 arranged side by side in the housing, and at least two mounting clamps 20. Further, along the width direction of the guide rail 10, the at least two mounting clamps 20 are arranged side by side on the two guide rails 10, and each mounting clamp 20 has a first edge 20a perpendicular to the running direction of the guide rail 10, and the length of the first edge 20a is less than the width of the guide rail 10, so that when the two mounting clamps 20 are placed on the two guide rails 10 respectively, any mounting clamp 20 will not extend out of the guide rail 10 it is placed on, thereby preventing the mounting clamp 20 from extending out to the adjacent guide rail 10, which would cause the mounting module on each guide rail 10 to mount it, resulting in the problem of color difference on different parts of the same circuit board 200.

[0032] In an embodiment, the housing is a hollow rectangular structure to accommodate the two guide rails 10 and the mounting device 100. It can be understood that the shape of the housing is not limited to this, and other frames that can accommodate the guide rails 10 and the mounting clamps 20 are also available.

[0033] It should be noted that at least one mounting module (not shown) is included above each guide rail 10, which is used to mount the specified area, i.e., the area below the module in the vertical direction. In an embodiment, the above-mentioned mounting module is a mechanical arm to grab lamp beads or other electronic components and mount the lamp beads or electronic components to the specified position on the circuit board 200. Preferably, the above-mentioned mounting module is controlled by a computer program, and this is part of the prior art, which will not be described here.

[0034] Further, in order to reduce the volume of the mounting device 100 on the basis of mounting, the length of the first edge 20a is in the range of 50mm-250mm, so that when the two mounting clamps 20 are placed on the two guide rails 10, the two mounting clamps 20 are evenly laid along the transverse direction of the housing to reduce the volume of the internal cavity of the housing.

[0035] In an embodiment, the first side 20a has a length of 247.5 mm. However, it is obvious that the length of the first side 20a is not limited to this, and in another embodiment, the length of the first side 20a can also be 50 mm, 70 mm, 90 mm, 110 mm, 130 mm, 150 mm, 170 mm, 190 mm, 210 mm, 230 mm, 241 mm, 242 mm, 243 mm, 244 mm, 245 mm, 246 mm, 247 mm, 248 mm, 249 mm, 250 mm, and the like.

[0036] It should be noted that in the existing mounting machine, the width of a single mounting module is 247.5 mm, and the above scheme sets the width of the mounting jig 20 to be consistent with the width of a single mounting module, so as to avoid the problem of excessive space occupancy caused by the excessive width of the mounting jig 20, thereby reducing the volume of the mounting device 100, reducing the floor area, and reducing the distance of the tile module moving in the cavity of the shell, thereby increasing the mounting efficiency.

[0037] Further, each mounting jig 20 also has a second side 20b parallel to the running direction of the guide rail 10. Specifically, the length of the second side 20b ranges from 306 mm to 380 mm to support the circuit board 200.

[0038] It should be noted that in the prior art, the second side 20b is usually placed along the direction perpendicular to the running direction of the guide rail 10 to form the existing mounting machine, and when the second side 20b is placed along the direction perpendicular to the running direction of the guide rail 10, the second side 20b will extend from the mounting jig 20 to the adjacent mounting jig 20, thereby occupying two mounting jigs 20, and when occupying two mounting jigs 20, the mounting modules located above the two guide rails 10 simultaneously perform the mounting operation on the circuit boards 200 on the mounting jigs on the two guide rails 10, thereby performing the mounting operation of the lamp beads in two different areas, and thereby forming color difference in different areas of the circuit board 200.

[0039] It should be noted that each mounting module mounts lamp beads of different colors and disorderedly fits them, and when the same circuit board 200 is mounted by two mounting modules, different lamp beads will be mounted on the same circuit board 200, thereby causing color difference when emitting light.

[0040] In an embodiment, the length of the second side 20b is 360 mm. However, it is obvious that the length of the second side 20b is not limited to this, and in another embodiment, the length of the second side 20b can also be 304 mm, 310 mm, 320 mm, 330 mm, 340 mm, 350 mm, 370 mm, or 380 mm, and the like.

[0041] Please refer to Figure 2In order to clamp the circuit board 200 on the mounting fixture 20, the mounting device 100 further comprises a clamping member 30. Specifically, the mounting fixture 20 comprises a clamping portion 21 and a support portion 22 arranged around the clamping portion 21. Further, the clamping member 30 is arranged at the position of the clamping portion 21 for clamping the circuit board 200 on the clamping portion 21.

[0042] In an embodiment, the clamping member 30 comprises, but is not limited to, a clamping jaw.

[0043] Further, in order to clamp the circuit board 200 on the mounting fixture 20, in an embodiment, the number of the clamping member 30 is four, and the four clamping members 30 are arranged at the four corners of the clamping portion 21 respectively. When the circuit board 200 is placed on the clamping portion 21, the four clamping members 30 clamp the four corners of the circuit board 200 respectively, so as to prevent the circuit board 200 from shaking.

[0044] In an embodiment, the clamping portion 21 and the support portion 22 are integrally formed, and the clamping portion 21 is located at the central part of the support portion 22.

[0045] In order to clamp the circuit board 200 on the mounting fixture 20, along the width direction of the guide rail 10, the support portion 22 has a first area 221 located at the front and back ends of the clamping portion 21. The circuit board 200 is fixed on the first area 221, so as to fix the circuit board 200 from both sides, thereby ensuring the firmness of the fixing of the circuit board 200 on the mounting fixture 20.

[0046] Further, in order to better ensure the firmness of the fixing of the mounting fixture 20 on the circuit board 200, the mounting device 100 further comprises an arch prevention member 40. Specifically, the arch prevention member 40 is arranged on the first area 221, and the circuit board 200 is fixed on the arch prevention member 40, so as to prevent the circuit board 200 from arching due to transportation during mounting.

[0047] In an embodiment, the arch prevention member 40 is substantially a rectangular block structure, and the number of the arch prevention member 40 is two. The two arch prevention members 40 are arranged at the front and back ends of the clamping portion 21 along the width direction of the guide rail 10, and the opposite side edges of the circuit board 200 abut against the arch prevention members 40 respectively, so that the circuit board 200 is clamped between the two arch prevention members 40. Preferably, the opposite side surfaces of the two arch prevention members 40 are provided with protrusions (not shown in the figure), so as to be clamped on the circuit board 200.

[0048] It can be understood that the fixing manner of the arch prevention member 40 on the circuit board 200 is not limited to this, such as in another embodiment, the width of the circuit board 200 is greater than the distance between the two arch prevention members 40, and the upper end surfaces of the two arch prevention members 40 are provided with protrusions (not shown in the figure), and the circuit board 200 is directly arranged on the upper end surfaces of the two arch prevention members 40 and clamped in the protrusions.

[0049] In an embodiment, in order to prevent the problem of the circuit board 200 sinking due to mounting, the width of the first area 221 is 70 mm, so that when the circuit board 200 is mounted, it abuts against the mounting jig 20, thereby preventing the circuit board 200 from sinking due to the width of the first area 221 being too small.

[0050] It should be noted that when the mounting jig 20 is in use, the first area 221 abuts against the guide rail 10 to be supported and stressed. Please refer to Figure 2 In the prior art, the area abutting against the guide rail 10 is the part of the mounting jig 20 perpendicular to the first area 221, and the width of the area is smaller than that of the first area 221, so that when it abuts against the guide rail 10, the stress-receiving part of the mounting jig 20 is prone to sink downward when the circuit board 200 is mounted, thereby affecting the mounting yield of the circuit board 200.

[0051] In order to prevent the problem of the mounting device 100 overheating due to heat generated during mounting, thereby affecting the mounting precision, the first area 221 is provided with a plurality of heat dissipation holes 221a for heat dissipation, so that the heat generated in the mounting device 100 is dissipated through the plurality of heat dissipation holes 221a.

[0052] The present application makes the first edge 20a of the mounting jig 20 smaller than the width of the guide rail 10, so that two mounting jigs 20 can be placed side by side on two guide rails 10 in the width direction of the guide rail 10, and when one mounting jig 20 is placed on one guide rail 10, the mounting jig 20 will not extend into the adjacent guide rail 10, thereby preventing the problem of color difference of the circuit board 200 caused by two different mounting modules simultaneously mounting two areas on one circuit board 200.

[0053] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
