Description

Technical Field

[0001] The utility model relates to the technical field of furniture assembly equipment, and particularly relates to a machine suitable for assembling drawers. Background Art

[0002] A drawer is a component of furniture such as cabinets, and is assembled by a drawer bottom plate, a pair of side plates, a back plate and a front panel. The drawer plates are fixed to each other through the cooperation of adhesives and pins.

[0003] Traditionally, drawers are assembled manually, but the work efficiency of manual assembly is relatively low. With the thinner thickness of drawer plates and higher requirements for assembly accuracy, the working hours consumed by manual assembly are getting longer and longer.

[0004] For this reason, some machines suitable for assembling drawers have been proposed in the prior art. For example, an automated machine disclosed in the utility model patent with the publication number CN209811689U and the name "Numerical Control Drawer Assembling Machine" uses a bottom plate suction cup 4 to fix the drawer back plate, and then presses on the joints of a pair of side plates, the back plate and the front panel of the drawer respectively through four corner blocks 9, 11, 12, 15 to complete the assembly of the drawer.

[0005] However, the pre-assembled drawer is first fixed by the bottom plate suction cup 4, and then pressed by the four corner blocks 9, 11, 12, 15 at the outer corners of the drawer. During this process, due to the relatively small contact area, the stability and accuracy of pressing are relatively low, and it is also easy to shift during the assembly process. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a drawer assembling machine, which can overcome at least one of the above technical problems. The following technical solutions are specifically adopted:

[0007] A drawer assembling machine includes a frame, an assembling device fixedly installed through the frame, and a control cabinet. The assembling device includes a workbench, a front panel backing plate located on one side of the workbench, a bottom plate backing plate located behind the workbench, a back plate pressing mechanism arranged opposite to the front panel backing plate, and a side plate pressing mechanism arranged opposite to the surface of the workbench. The back plate pressing mechanism includes a back plate pressing plate and a translational power unit capable of moving the back plate pressing plate towards or away from the front panel backing plate. The side plate pressing mechanism includes a side plate pressing plate and a lifting power unit capable of lifting the side plate pressing plate towards or away from the workbench. Among them, the front panel backing plate, the bottom plate backing plate and the back plate pressing plate all extend in a direction perpendicular to the workbench and have a certain height.

[0008] With the above structure, the panel backing plate, the bottom plate backing plate, and the back panel pressing plate all extend in a direction perpendicular to the workbench and have a certain height. Therefore, even if the assembled drawer has a relatively large width, the abutting support of the panel backing plate and the bottom plate backing plate against the panel and the bottom plate of the drawer can cover the entire width of the two to provide reliable and stable support. At the same time, the abutting support of the back panel pressing plate against the back panel of the drawer can cover the entire width, so as to cooperate with the panel backing plate to provide a reliable and stable pressing force in the x-axis direction.

[0009] Preferably, the back panel pressing plate and the side panel pressing plate can move synchronously towards or away from the panel backing plate.

[0010] In the above technical solution, the linkage of the back panel pressing plate and the side panel pressing plate can ensure that the pressure application position of the side panel pressing plate is close to the back panel. In other words, the pressure center of the side panel pressing plate is perpendicular to and as close as possible to the axis of the connecting pin of the back panel, so that the operation of the side panel pressure mechanism is more stable and the accuracy is higher.

[0011] Preferably, the back panel pressing plate is fixedly installed on the frame, the side panel pressing plate is arranged on the frame so as to be able to move up and down towards or away from the workbench, and the frame can move towards or away from the panel backing plate under the drive of the translation power unit.

[0012] Preferably, a pair of first guide rails extending in a direction perpendicular to the workbench are arranged on the frame and are located on both sides of the back panel pressing plate. A slider cooperating with the first guide rail is provided on the first side of the side panel pressing plate.

[0013] Preferably, the side panel pressure mechanism further includes a movable guide rail and a second guide rail; the second guide rail extends in a direction perpendicular to the workbench; the movable guide rail is located behind the bottom plate backing plate and is arranged horizontally, and has a slider cooperating with the second guide rail thereon and is driven by the lifting power unit; the second side of the side panel pressing plate extends towards the movable guide rail and has a slider cooperating with the movable guide rail.

[0014] Preferably, the side panel pressure mechanism further includes a lateral pressing strip arranged between the panel backing plate and the side panel pressing plate. The lateral pressing strip is arranged at a lateral distance from the panel backing plate, and the distance is 1.5 cm - 3.0 cm.

[0015] Preferably, the lateral pressing strip is fixedly arranged on the movable guide rail.

[0016] Preferably, at least the bottom surface of the lateral pressing strip has an elastic cushion strip.

[0017] Preferably, the workbench forms an angle of 5° - 30° with the horizontal plane.

[0018] Preferably, the drawer assembly machine includes a plurality of the assembly devices.

[0019] In summary, compared with the prior art, the drawer assembly machine of the present utility model can assemble drawers stably and with high precision. Description of the Drawings

Detailed Embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0026] Referring to Figure 2-3 a drawer assembly machine shown in the figure, which is applicable to assembling and fastening a pre-assembled drawer 9, and specifically includes a frame 1, an assembly device A fixedly installed through the frame 1, and a control cabinet. The frame 1 can be any metal frame structure in the prior art, and is suitable for providing a space for supporting, fixing, and installing the assembly device A. The control cabinet can be any feasible product in the prior art, such as a PLC control cabinet.

[0027] The assembly device A includes a device frame 7, a workbench 2, a panel backing plate 3 on one side of the workbench 2, a bottom plate backing plate 4 behind the workbench 2, a back plate pressing mechanism 5 arranged opposite to the panel backing plate 3, and a side plate pressing mechanism 6 arranged opposite to the tabletop of the workbench 2 and above the workbench 2.

[0028] The device frame 7 can be any metal frame structure in the prior art, suitable for providing a space for supporting, fixing and installing various components and mechanisms of the assembly device A. Generally, the device frame 7 includes a frame base 71, side vertical plates 72, and a frame top beam 73.

[0029] Specifically, the workbench 2 is screwed and installed on the frame base 71, and its tabletop is a supporting working surface. The panel backing plate 3 is screwed and installed on the side vertical plate 72, and its vertical surface facing the workbench 2 is a backing working surface. The lower end of the bottom plate backing plate 4 is screwed and installed on the frame base 71, and the upper end is screwed and installed on the frame top beam 73, and its vertical surface facing the workbench 2 is a backing working surface.

[0030] Set the width direction of the plane where the supporting working surface of the workbench 2 is located as the x-axis direction, the depth direction as the y-axis direction, and the direction perpendicular to this supporting working surface as the z-axis direction. Thus, the workbench 2 can provide support in the x-y plane, the panel backing plate 3 can provide limit in the y-z plane, and the bottom plate backing plate 4 can provide limit in the x-z plane.

[0031] Particularly, both the panel backing plate 3 and the bottom plate backing plate 4 extend in a direction perpendicular to the workbench 2 (i.e., the z-axis direction) and have a certain height. Therefore, even if the assembled drawer 9 has a relatively large width, the abutting support of the panel backing plate 3 and the bottom plate backing plate 4 on the panel 94 and the bottom plate 91 of the drawer 9 can cover the entire width of the two, thereby providing reliable and stable support.

[0032] There is a spacing between the workbench 2 and the panel backing plate 3 and the bottom plate backing plate 4 to avoid interference among the three.

[0033] The back plate pressing mechanism 5 includes a back plate pressing plate 51 and a translational power unit 52 that can move the back plate pressing plate 51 towards or away from the panel backing plate 3. The back plate pressing plate 51 is arranged opposite to the panel backing plate 3, and its vertical surface facing the panel backing plate 3 is a pressing working surface, capable of providing a pressing force towards the panel backing plate 3.

[0034] Particularly, the back plate pressing plate 51 extends in a direction perpendicular to the workbench 2 (i.e., the z-axis direction) and has a certain height. Therefore, similarly, even if the assembled drawer 9 has a relatively large width, the abutting support of the back plate pressing plate 51 on the back plate 93 of the drawer 9 can cover the entire width, thereby cooperating with the panel backing plate 3 to provide a reliable and stable pressing force in the x-axis direction.

[0035] The side plate pressing mechanism 6 includes a side plate pressing plate 61 and a lifting power unit 62 capable of lifting the side plate pressing plate 61 towards or away from the workbench 2.

[0036] During operation, the drawer 9 is placed on the workbench 2 with one side plate 92 facing downwards, the panel 94 abuts against the panel backing plate 3, and the bottom plate 91 abuts against the bottom plate backing plate 4. Subsequently, the translation power unit 52 electrically connected to the control cabinet drives the back plate pressing plate 51 to translate towards the panel backing plate 3 to compress the connections between the side plate 92 and the panel 94, and between the bottom plate 91, the panel 94, and the back plate 93. The lifting power unit 62 electrically connected to the control cabinet drives the side plate pressing plate 61 to descend towards the workbench 2 to compress the connections between the side plate 92 and the back plate 93, and between the side plate 92 and the bottom plate 91. Finally, the translation power unit 52 drives the back plate pressing plate 51 to translate away from the panel backing plate 3 to release the compression of the back plate pressing plate 51 on the back plate 93, and the lifting drive unit 62 drives the side plate pressing plate 61 to rise away from the workbench 2 to release the compression of the side plate pressing plate 61 on the side plate 92.

[0037] As a preferred embodiment, the back plate pressing plate 51 and the side plate pressing plate 61 can move synchronously towards or away from the panel backing plate 3. The synchronous movement of the back plate pressing plate 51 and the side plate pressing plate 61 in the x-axis direction can ensure that the pressing position of the side plate pressing plate 61 is close to the back plate 93. In other words, the pressure center of the side plate pressing plate 61 is perpendicular to and as close as possible to the axis of the connecting pin of the back plate 93, thereby making the operation of the side plate pressing mechanism 6 more stable and with higher precision.

[0038] Specifically, the linkage of the back plate pressing plate 51 and the side plate pressing plate 61 is achieved through the following structure.

[0039] On the front and rear surfaces of the frame base 71, a pair of third guide rails 55 are respectively screwed. On the front and rear surfaces of the frame top beam 73, a pair of fourth guide rails 56 are respectively screwed. The third guide rails 55 and the fourth guide rails 56 both extend in the x-axis direction. The frame 53 includes a pair of frame vertical beams 531 extending in the z-axis direction and a plurality of frame cross beams 532 connecting the pair of frame vertical beams 531. On the bottom of the opposite surfaces of the pair of frame vertical beams 531, sliders cooperating with the third guide rails 55 are respectively screwed. On the top of the opposite surfaces of the pair of frame vertical beams 531, sliders cooperating with the fourth guide rails 56 are respectively screwed. Thus, the frame 53 is installed on the device frame 7 through the third guide rails 55 and the fourth guide rails 56 and can move in the x-axis direction under the drive of the translation power unit 52. Preferably, limit blocks are provided at both ends of the third guide rails 55 and the fourth guide rails 56.

[0040] The back plate pressing plate 51 is screwed and installed on the frame cross beam 532.

[0041] At the same time, a pair of frame beams 531 are located on both sides of the back plate pressing plate 51, and the pair of frame beams 531 are both screwed with first guide rails 54, and the first guide rails 54 extend along the z-axis direction. The side plate pressing plate 61 is screwed on the side mounting plate 68, and a slider matching the first guide rail 54 is screwed on the back of the side mounting plate 68, so that the side plate pressing plate 61 can be translated along the x-axis synchronously with the frame 53 and the back plate pressing plate 51, and can also be relatively lifted and lowered along the z-axis direction with the back plate pressing plate 51.

[0042] Preferably, the translational force unit 52 is a servo gear rack system of the prior art, for example, including gear racks respectively arranged on the frame base 71 and the frame top beam 73, a servo motor screwedly mounted on the back of the frame cross beam 532, a driving wheel mounted on the output shaft of the servo motor through a bearing, two gears respectively meshed with the two gear racks, a transmission shaft passing through the two gears through a bearing, a transmission wheel sleeved on the transmission shaft, and a transmission belt connecting the driving wheel and the transmission wheel, and the transmission shaft is fixedly connected to the back of the frame cross beam 532 through a shaft sleeve, etc.

[0043] In order to cooperate with the structure of the linkage between the back plate pressure plate 51 and the side plate pressure plate 61, the structure of the side plate pressure mechanism 6 is as follows.

[0044] The second guide rail 64 is screwed onto the side plate 72 and extends in a direction perpendicular to the workbench 2 (z-axis direction).

[0045] The movable guide rail 63 arranged transversely (in the x-axis direction) is located behind the bottom plate support plate 4, and a slider matching with the second guide rail 64 is screwed on one end thereof, and is driven by the lifting power unit 62. The second side of the side plate pressing plate 61, for example, the end surface of the side mounting plate 68 extends toward the movable guide rail 63, and a slider matching with the movable guide rail 63 is screwed on the end surface.

[0046] Preferably, the lifting power unit 62 is a servo screw system of the prior art. For example, the lifting power unit 62 includes a servo motor screwed on the back of the side plate 4, a driving wheel connected to the output shaft of the servo motor through a bearing, a transmission wheel screwed on the back of the side plate 4, a transmission belt connecting the driving wheel and the transmission wheel, a transmission screw driven by the transmission wheel, and a transmission nut sleeved on the transmission screw, and the transmission nut is screwed and fixedly connected to the movable guide rail 63.

[0047] During operation, the translation power unit 52 can push the frame 53 and carry the back panel pressure plate 51 toward the panel support plate 3, and at the same time, the side panel pressure plate 61 is guided by the movable guide rail 63 and moves toward the panel support plate 3 along with the back panel pressure plate 51; the lifting power unit 62 can push the movable guide rail 63 down toward the workbench 2, and at the same time press down the side panel pressure plate 61 that slides with it.

[0048] In order to make the pressure center of the side plate pressing plate 61 perpendicular to and as close as possible to the axis of the connecting pin of the back plate 93, so that the operation of the side plate pressing mechanism 6 is more stable and the accuracy is higher, the side plate pressing plate 61 always follows the back plate pressing plate 51 and maintains diagonality. However, in this implementation, if the drawer 9 has a relatively large depth, and the force application point of the side plate pressing plate 61 is close to the back plate 93 and far from the front panel 94, it is easy to affect the assembly accuracy of the drawer 9 due to uneven force application.

[0049] Therefore, in order to further improve the assembly accuracy of the drawer assembly machine of this embodiment, as a preferred implementation, the side plate pressing mechanism 6 further includes a lateral pressing strip 65 disposed between the front panel backing plate 3 and the side plate pressing plate 61. Specifically, the lateral pressing strip 65 is screwed to the movable guide rail 63, its bottom surface facing the bottom surface of the workbench 2 is the pressing working surface, and the bottom surface of the lateral pressing strip 65 is at the same height as the bottom surface of the side plate pressing plate 61. In order to avoid the bottom plate backing plate 4, the lateral pressing strip 65 is located between the front panel backing plate 3 and the bottom plate backing plate 4.

[0050] However, the force application direction of the lateral pressing strip 65 is in the z-axis direction, and the axial direction of the connecting pin between the front panel 94 and the side plate 92 is in the x-axis direction. Therefore, the setting of the lateral pressing strip 65 easily causes the connecting pin connecting the front panel 94 and the side plate 92 to be offset or misaligned, which will instead affect the assembly accuracy of the drawer 9.

[0051] To overcome the above problems, an elastic cushion strip 66 is screwed or bonded to the bottom surface of the lateral pressing strip 65. The elastic cushion strip 66 can be any elastic material in the prior art. Preferably, its hardness is about 70°.

[0052] In some embodiments, in order to keep the downward pressing amounts of the side plate pressing plate 61 and the lateral pressing strip 65 always equal, an elastic gasket 67 is screwed or bonded to the bottom surface of the side plate pressing plate 61. The material and hardness of the elastic gasket 67 are the same as those of the elastic cushion strip 66.

[0053] Refer to Figure 1 For the shown drawer 9, the width of the front panel 94 is larger than that of the back plate 93. In order to avoid the front panel surface 94, the lateral pressing strip 65 and the front panel backing plate 3 are spaced apart in the transverse direction. Preferably, the spacing is 1.5 cm - 3.0 cm, so that it can not only avoid the protruding part of the front panel surface 94, but also make the force application position of the lateral pressing strip 65 as close as possible to the front panel 94.

[0054] In some preferred embodiments, the workbench 2 forms an angle of 5° - 30° with the horizontal plane. In other words, the x-y plane forms an angle of 5° - 30° with the horizontal plane, and at the same time, the x-axis, y-axis, and z-axis are perpendicular to each other in pairs.

[0055] In some preferred embodiments, the drawer assembly machine includes a plurality of assembly devices A fixedly installed on the frame 1.

[0056] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
