Description

Technical Field

[0001] The utility model relates to the technical field of furniture assembly equipment, and particularly relates to a machine capable of assembling drawers of various styles and specifications. 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 applicable to drawer assembly 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 of "Numerical Control Drawer Assembly Machine" uses a bottom plate suction cup 4 to fix the drawer back plate, and then applies pressure to the joints of a pair of drawer side plates, the back plate and the front panel through four corner blocks 9, 11, 12, 15 respectively to complete the assembly of the drawer.

[0005] However, the above-mentioned machine has the problem of extremely low versatility. Specifically, theoretically, after pre-assembly, the drawer side plates and the back plate are of the same height, and the front panel and the back plate are of the same width. But in fact, as shown in Figure 1 the height of the back plate is often greater than that of the side plates, the top surfaces of the three are flush, the lower part of the back plate extends out, and the width and height of the front panel are both greater than those of the back plate. Drawers with such a structure cannot be assembled using the above-mentioned prior art machine, and the adsorption of the bottom plate suction cup 4 and the contact pressure applied by the four corner blocks 9, 11, 12, 15 will cause interference, resulting in the working part being unable to contact each drawer plate. Summary of the Utility Model

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

[0007] A versatile drawer assembly machine includes a frame, an assembly device fixedly installed through the frame, and a control cabinet. The assembly 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 pressure mechanism disposed opposite to the front panel backing plate, and a side plate pressure mechanism disposed opposite to the surface of the workbench; there is a first gap between the side surface of the workbench and the front panel backing plate, and a second gap between the side surface of the bottom plate backing plate and the front panel backing plate. The widths of the first gap and the second gap are both not less than 2 cm.

[0008] With the above structure, one side plate of the pre-assembled drawer is placed on the workbench surface, and the part of the panel extending beyond the side plate can extend into the first gap and the second gap. Therefore, the panel can be in contact with and supported by both the panel backing plate and the bottom plate backing plate simultaneously. Thus, the universal drawer assembling machine of the present application can be adapted to the assembly of conventional drawers with the panel being of the same height as the side plate and the same width as the bottom plate, and can also be applicable to the assembly of drawers with styles where the four side surfaces of the panel extend beyond the side plate and / or the bottom plate, having relatively high versatility.

[0009] Preferably, the width of the bottom plate backing plate is 15 cm - 20 cm.

[0010] Preferably, 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. There is a third gap between the side plate pressing plate and the panel backing plate.

[0011] Preferably, the width of the third gap is not less than 2 cm.

[0012] Preferably, the side plate pressing plate can move towards or away from the panel backing plate.

[0013] Preferably, the back plate pressing mechanism includes a back plate pressing plate and a translation power unit capable of moving the back plate pressing plate and the side plate pressing plate towards or away from the panel backing plate simultaneously.

[0014] Preferably, the side plate pressing mechanism further includes a side plate pressing strip disposed between the panel backing plate and the side plate pressing plate.

[0015] Preferably, the position of the side plate pressing strip is fixed in the transverse direction.

[0016] Preferably, there is a fourth gap between the side surface of the side plate pressing strip and the panel backing plate, and the width of the fourth gap is 1.5 cm - 3.0 cm.

[0017] Preferably, there is an avoidance notch on the outer side of the panel backing plate.

[0018] Compared with the prior art, the drawer assembling machine of the present utility model has relatively high versatility. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[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] Refer to Figure 2-5 A drawer assembly machine as shown, which is applicable to assembling and fastening a pre-assembled drawer 9. Specifically, it 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 located on one side of the workbench 2, a bottom plate backing plate 4 located behind the workbench 2, a back panel pressing mechanism 5 arranged opposite to the panel backing plate 3, and a side panel pressing mechanism 6 arranged opposite to the tabletop of the workbench 2 and located above the workbench 2.

[0028] The device frame 7 can be any metal frame structure in the prior art, and is 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 the 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 the 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. Its vertical surface facing the workbench 2 is the 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 the 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] There is a gap between the workbench 2 and the panel backing plate 3 and the bottom plate backing plate 4 to avoid interference among the three. Specifically, there is a first gap L1 between the side surface of the workbench 2 and the panel backing plate 3, and a second gap L2 between the side surface of the bottom plate backing plate 4 and the panel backing plate 3. And the widths of both the first gap L1 and the second gap L2 are not less than 2 cm. Preferably, the width of the bottom plate backing plate 4 is 15 cm - 20 cm, such as 18 cm.

[0032] The back panel pressure mechanism 5 includes a back panel pressing plate 51 and a translational power unit 52 that can move the back panel pressing plate 51 towards or away from the panel backing plate 3. The back panel pressing plate 51 is arranged opposite to the panel backing plate 3, and its vertical surface facing the panel backing plate 3 is the pressing working surface, which can provide a pressing force towards the panel backing plate 3. The side panel pressure mechanism 6 includes a side panel pressing plate 61 and a lifting power unit 62 that can lift the side panel pressing plate 61 towards or away from the workbench 2. There is a third gap L3 between the side panel pressing plate 61 and the panel backing plate 3. Preferably, the width of the third gap L3 is not less than 2 cm. By setting the third gap L3 and limiting the width of the third gap, when the side panel pressing plate 61 presses the side panel 92, it will not be affected by the too long panel 94, thus ensuring the versatility of the drawer assembly machine in this embodiment.

[0033] During operation, one side plate 92 of the pre-assembled drawer 9 is placed on the workbench surface of the workbench 2, and the part of the panel 94 extending beyond the side plate 92 can extend into the first gap L1 and the second gap L2. Therefore, the panel 94 can be abutted against and supported by both the panel backrest 3 and the bottom plate backrest 4 simultaneously. Thus, the universal drawer assembling machine of the present application can be adapted to the assembly of conventional drawers with the panel and the side plate having the same height and the panel and the bottom plate having the same width, and can also be adapted to the assembly of drawers with the four sides of the panel extending beyond the side plate and / or the bottom plate, having high versatility. Additionally, by defining the width of the bottom plate backrest 4, the drawer assembling machine of this embodiment can be adapted to the assembly of drawers with one side of the back panel 93 extending beyond the bottom plate 91, further improving its versatility.

[0034] In order to enable the drawer 9 to be placed on the workbench 2 more smoothly, an avoidance notch 31 is provided on the outer side of the panel backrest 3. By means of the setting of the avoidance notch 31, it can not only ensure that the panel backrest 3 has a certain width to provide sufficient and stable support, but also avoid the over-wide panel backrest 3 from interfering with the feeding operation.

[0035] After the pre-assembled drawer 9 is placed, the translation power unit 52 electrically connected to the control cabinet drives the back panel pressing plate 51 to translate towards the panel backrest 3 to press the connections between the side plate 92 and the panel 94, and between the bottom plate 91, the panel 94 and the back panel 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 press the connections between the side plate 92 and the back panel 93, and between the side plate 92 and the bottom plate 91. Finally, the translation power unit 52 drives the back panel pressing plate 51 to translate away from the panel backrest 3 to release the pressing of the back panel pressing plate 51 on the back panel 93, and the lifting drive unit 62 drives the side plate pressing plate 61 to rise away from the workbench 2 to release the pressing of the side plate pressing plate 61 on the side plate 92.

[0036] As a preferred embodiment, the back panel pressing plate 51 and the side plate pressing plate 61 can move synchronously towards or away from the panel backrest 3. The synchronous movement of the back panel 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 panel 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 connection pin of the back panel 93, so that the operation of the side plate pressure mechanism 6 is more stable and has higher precision.

[0037] In this preferred embodiment, since the side plate pressing plate 61 will move in the x-axis direction, it should be defined that when the side plate pressing plate 61 moves towards the panel backrest 3 to the maximum stroke, there is still a third gap L3 of not less than 2 cm between them, for example, the distance is 10 cm.

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

[0039] A pair of third guide rails 55 are respectively screwed on the front and rear of the frame base 71, and a pair of fourth guide rails 56 are respectively screwed on the front and rear of the frame top beam 73. The third guide rails 55 and the fourth guide rails 56 both extend along the x-axis direction. The frame 53 includes a pair of frame vertical beams 531 extending along the z-axis direction and a plurality of frame cross beams 532 connecting the pair of frame vertical beams 531. Sliders cooperating with the third guide rails 55 are respectively screwed on the bottoms of the opposite faces of the pair of frame vertical beams 531, and sliders cooperating with the fourth guide rails 56 are respectively screwed on the tops of the opposite faces of the pair of frame vertical beams 531. 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 along 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 backplane pressing plate 51 is screwed and installed on the frame cross beam 532.

[0041] Meanwhile, the pair of frame vertical beams 531 are located on both sides of the backplane pressing plate 51, and a first guide rail 54 is respectively screwed on each of the pair of frame vertical beams 531. The first guide rail 54 extends along the z-axis direction. The side plate pressing plate 61 is screwed and installed on the side mounting plate 68, and a slider cooperating with the first guide rail 54 is screwed on the back of the side mounting plate 68. Thus, the side plate pressing plate 61 can not only translate synchronously with the frame 53 and the backplane pressing plate 51 along the x-axis direction, but also move relatively up and down along the z-axis direction with the backplane pressing plate 51.

[0042] Preferably, the translation power unit 52 is a servo gear-rack system in the prior art. For example, it includes racks respectively provided on the frame base 71 and the frame top beam 73, a servo motor screwed 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 meshing with the two racks, a transmission shaft passing through the two gears through bearings, a transmission wheel sleeved on the transmission shaft, and a transmission belt connecting the driving wheel and the transmission wheel. The transmission shaft is fixedly connected to the back of the frame cross beam 532 through a shaft sleeve or the like.

[0043] To match the structure of the linkage between the backplane pressing plate 51 and the side plate pressing plate 61, the structure of the side plate pressure mechanism 6 is as follows.

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

[0045] The movable guide rail 63 arranged horizontally (in the x-axis direction) is located behind the base plate backing plate 4. One end of it is provided with a slider that mates with the second guide rail 64 through screwing, and is driven by the lifting power unit 62. On the second side of the side plate pressing plate 61, for example, the end face of the side mounting plate 68 extends towards the movable guide rail 63, and a slider that mates with the movable guide rail 63 is provided through screwing on the end face.

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

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

[0048] In order to make the pressure center of the side plate pressing plate 61 perpendicular and as close as possible to the axis of the connecting pin of the back plate 93, so that the work of the side plate pressure mechanism 6 is more stable and has higher precision, the side plate pressing plate 61 always follows the back plate pressing plate 51 and maintains a diagonal. 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 panel 94, it is easy to affect the assembly precision of the drawer 9 due to uneven force application.

[0049] Therefore, in order to further improve the assembly precision of the drawer assembling machine in this embodiment, as a preferred implementation, the side plate pressure mechanism 6 further includes a lateral pressing strip 65 arranged between the panel backing plate 3 and the side plate pressing plate 61. Specifically, the lateral pressing strip 65 is screwed on the movable guide rail 63. Its bottom surface facing 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 base plate backing plate 4, the lateral pressing strip 65 is located between the panel backing plate 3 and the base plate backing plate 4.

[0050] Particularly, there is a fourth gap L4 between the side surface of the side plate pressing strip 65 and the panel backing plate 3, and the width of the fourth gap L4 is 1.5 cm - 3.0 cm. By limiting the width of the fourth gap L4, it is possible to enable the panel 94 to extend into the fourth gap L4 while avoiding the lateral pressing strip 65 being too far away from the panel backing plate 3.

[0051] However, the force application direction of the side caulking strip 65 is in the z-axis direction, and the axial direction of the connecting pin between the panel 94 and the side plate 92 is in the x-axis direction. Therefore, the setting of the side caulking strip 65 easily causes the connecting pin connecting the panel 94 and the side plate 92 to be offset or misaligned, which will instead affect the assembly accuracy of the drawer 9.

[0052] To overcome the above problems, an elastic gasket strip 66 is provided at the bottom surface of the side plate caulking strip 65 by screwing or bonding. The elastic gasket strip 66 can be any elastic material in the prior art. Preferably, its hardness is about 70°.

[0053] In some embodiments, in order to keep the downward pressing amounts of the side plate pressing plate 61 and the side caulking strip 65 always equal, an elastic gasket 67 is provided at the bottom surface of the side plate pressing plate 61 by screwing or bonding. The material and hardness of the elastic gasket 67 are the same as those of the elastic gasket strip 66.

[0054] By providing the elastic gasket strip 66 and the elastic gasket 67, in fact, the drawer assembling machine of this embodiment can be applicable to drawers with various pin connection methods, and can avoid the misalignment of the connecting pins.

[0055] 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.

[0056] In some preferred embodiments, the drawer assembling machine includes a plurality of assembling devices A fixedly installed on the frame 1.

[0057] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention 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 included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
