Description

Technical Field

[0001] The invention relates to the field of furniture processing, and in particular to a drilling device for processing paint holes in wooden doors. Background Art

[0002] Solid wood furniture is a type of furniture widely loved by consumers. Solid wood furniture is mainly composed of several wooden boards. In the process of processing solid wood furniture, the wood needs to be cut into wooden boards first, and then the wooden boards need to be processed by planing, trimming, carving, drilling, painting and other steps. After painting, before the paint on the surface of the wooden board solidifies, if the surface of the wooden board contacts other equipment, the paint on the surface of the wooden board will be damaged. At present, it is usually adopted to drill holes on the two opposite ends of the wooden board. After painting, columnar structures such as steel bars are inserted into the holes to position the wooden board. While avoiding the contact between the wooden board and other equipment, it will undoubtedly minimize the contact area between the wooden board and structures such as steel bars, and minimize the damage to the paint.

[0003] Currently, when drilling holes at the ends of wooden boards, the wooden boards need to be transported to the drilling process first, and then transported to the painting process. The wooden boards need to be transported multiple times. Taking door boards as an example, the length and width of the door boards are large, so the weight of the door boards is large. Multiple transportations will undoubtedly reduce the processing efficiency of the door boards and greatly increase the workload of manual labor. Summary of the invention

[0004] The present invention is intended to provide a drilling device for processing paint holes in wooden doors, so as to drill holes at the ends of wooden boards during transportation, so as to reduce the number of transportation times, improve processing efficiency and reduce manual workload.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a drilling device for processing paint holes in wooden doors, comprising a transport unit, a first drilling unit and a second drilling unit, the transport unit comprising a transport drive and a transport member for moving a wooden board, the transport drive being used to drive the transport member to rotate; the first drilling unit and the second transport unit are both located above the transport member and respectively located at both ends of the transport member; the first drilling unit and the second drilling unit both comprise a vertical drive and a drilling assembly, the first drilling unit further comprises a sliding assembly, the sliding assembly comprises a sliding drive and a slide that can slide along the moving direction of the wooden board, the sliding drive is connected to the slide and is used to drive the slide to slide, the second drilling unit further comprises A fixed plate, two vertical driving members are respectively fixed on the slide plate and the fixed plate; the two drilling assemblies are both lower than the vertical driving members, and the drilling assemblies each include a drill bit, a drilling driving member and a mounting seat, the two vertical driving members are respectively connected to the two mounting seats and respectively drive the two mounting seats to move vertically, the two drill bits are respectively connected to the two drilling driving members laterally, the drilling driving member of the first drilling unit is arranged on the mounting seat of the first drilling unit; a second adjustment driving member is fixed on the mounting seat of the second drilling unit and is slidably connected to a second adjustment plate along the moving direction of the wooden board, the second adjustment driving member is connected to the second adjustment plate and is used to drive the second adjustment plate to slide, and the drilling driving member of the second drilling unit is fixed on the second adjustment plate.

[0006] The beneficial effects of this program are:

[0007] 1. The first drilling unit and the second drilling unit in the present solution are arranged above the transport member, and the transport member can transport the template. When it is necessary to drill holes at the ends of the wooden board, the vertical driving members on the first drilling unit and the second drilling unit can drive the mounting seat to slide vertically, and the sliding driving member can drive the slide plate to slide, so that the drill bit in the first drilling unit is close to the wooden board. At this time, the drill bits in the first drilling unit and the second drilling unit can drill holes at both ends of the wooden board respectively, without first transporting the wooden board to the drilling process and then transporting the wooden board to the next process after drilling. This improves the processing efficiency while reducing the workload of transporting the wooden board.

[0008] 2. The first drilling unit and the second drilling unit in this solution are respectively located at the two ends of the transport member. When the wooden board moves along the transport member, it automatically approaches the second drilling unit. Therefore, the vertical driving member in the second drilling unit in this solution does not need to slide horizontally, which can simplify the drilling operation.

[0009] Furthermore, the transport member comprises two annular transport belts, the upper part of the transport belts is a transport portion, a support plate is provided below the transport portion, and the top of the support plate abuts against the bottom of the transport portion.

[0010] The beneficial effects of this solution are: currently, spaced transport rollers are usually used to transport plates. Compared with transport rollers, the contact area between the conveyor belt and the plate in this solution is larger, the friction between the plate and the conveyor belt is greater, and it is less likely to slide relative to the conveyor belt when drilling, making drilling more convenient.

[0011] Furthermore, a positioning unit is provided above the transport member, and the positioning unit includes a pressing plate and a positioning driving member, and the positioning driving member is connected to the pressing plate and is used to make the pressing plate slide vertically.

[0012] The beneficial effect of this solution is that when drilling, the positioning drive member drives the pressure plate to slide downward to press the plate, further preventing the plate from sliding relative to the drill bit, making drilling easier.

[0013] Furthermore, a centering unit is provided under the pressure plate, and the centering unit includes a centering drive member and two pushing members, the two pushing members are respectively located on both sides of the transport member, the centering drive member is connected to the two pushing members and is used to drive the two pushing members to move closer to and away from each other.

[0014] The beneficial effect of this solution is as follows: after the wooden board is placed on the transport member, the wooden board is located between the two pushing members. When the centering driving member drives the two pushing members closer to each other, the pushing member can push the wooden board along the transport direction of the wooden board and push the wooden board to the middle of the two pushing members, thereby ensuring that the wooden board is aligned with the drill bit, making it easier for the drill bit to drill holes in the wooden board.

[0015] Furthermore, the centering unit also includes a flexible ring, the angle between the flexible ring and the moving direction of the wooden board is greater than 0° and less than 180°, the flexible ring is lower than the transport member and the flexible ring can rotate relative to the transport member, and the centering drive member is connected to the flexible ring and is used to drive the flexible ring to rotate; the flexible ring includes a first transmission part on the upper side and a second transmission part on the lower side, and two pushing members are respectively connected to the first transmission part and the second transmission part.

[0016] The beneficial effect of this solution is that when the centering drive member drives the flexible ring to rotate, the movement directions of the first transmission part and the second transmission part are opposite, and the two mounting frames can be driven in opposite directions. Therefore, only one centering drive member is needed to drive the two mounting frames to slide at the same time, effectively simplifying the structure of the feeding mechanism.

[0017] Furthermore, the centering unit also includes a slide rail, which extends along the length direction of the flexible ring, and the pushing member is slidably connected to the slide rail.

[0018] The beneficial effect of this solution is that the slide rail can guide the sliding of the mounting frame to prevent the pushing member from tilting during the movement, thereby ensuring that the pushing member can push the wooden board to a predetermined position.

[0019] Furthermore, the pushing member includes a mounting frame and a pushing roller, the mounting frame is mounted on the slide rail and is slidably connected to the slide rail, and the two mounting frames are respectively connected to the first transmission part and the second transmission part; the pushing roller is vertically mounted on the mounting frame and is rotatably connected to the mounting frame, and the top of the pushing roller is higher than the top of the transport member.

[0020] The beneficial effect of this solution is that when the pushing member pushes the wooden board, the wooden board still moves with the transport member, so there is still relative movement between the wooden board and the pushing member. The pushing member in this solution can rotate to avoid sliding friction between the wooden board and the pushing member, thereby avoiding wear of the wooden board and the pushing member.

[0021] Furthermore, a buffer layer is fixed to the side wall of the push roller.

[0022] The beneficial effect of this solution is that the buffer layer prevents the hard pushing member from directly contacting the wooden board, and avoids the formation of indentations on the wooden board when processing the wooden board with lower hardness.

[0023] Furthermore, the first drilling unit also includes a limiting assembly, which includes a strip plate and an L-shaped chain. The strip plate is laterally arranged above the vertical driving member, and the slide plate can slide along the strip plate. The chain is located above the strip plate, and the bottom of the chain is against the top of the strip plate. The chain includes a plurality of connecting plates, and the vertical cross-section of the connecting plates is annular. Adjacent connecting plates are hinged, and the two ends of the chain are respectively connected to the slide plate and the strip plate.

[0024] The beneficial effects of the present scheme are as follows: the chain in the present scheme is bendable, and during the sliding of the skateboard, the end of the chain close to the skateboard moves with the skateboard, so that the bending part of the chain keeps changing, while the total length of the chain does not change. Therefore, the power cord connected to the power parts such as the vertical drive parts and the drilling drive parts that need to be connected to the power supply to work can be arranged in the chain. At this time, the chain can limit the power cord to prevent the power cord from slipping, and when the chain is bent, the power cord close to the power part can also move with the power part to prevent the power cord from being pulled.

[0025] Furthermore, it also includes a guide unit, which includes a support seat and two guide assemblies. The guide assemblies are respectively on the same side as the two pushing members. The guide assemblies include a guide plate and a guide wheel. The guide wheel is rotatably connected to the guide plate, and the rotation center of the guide wheel is parallel to the moving direction of the wooden board; the guide plate is vertically slidably connected to the support seat, and a guide drive member for pushing the guide plate vertically is fixed on the support seat.

[0026] The beneficial effect of this solution is that when the transport member drives the wooden board to slide, the top of the guide wheel is lower than the top of the transport member, and the wooden board only contacts the transport member and moves under the action of the transport member, which can avoid the wooden board from contacting the guide wheel and causing scratches on the wooden board. When the push member pushes the wooden board to slide, the guide plate slides upward under the action of the guide drive member, so that the height of the guide wheel is increased. At this time, the top of the guide wheel is higher than the transport member, so the guide wheel can support the wooden board and make the wooden board separate from the transport member. Therefore, when the push member pushes the wooden board to slide horizontally, the guide wheel in this solution rotates to reduce the friction force on the wooden board, further avoiding scratches on the wooden board.

[0044] For example Figure 1 and Figure 2 As shown, a guide unit is provided on the left side of each centering unit. The guide unit includes a support seat and two guide assemblies. The support seat is in the shape of a long strip, and the front and rear ends of the support seat are fixed to the frame 1 by bolts.

[0045] The specific implementation process is as follows:

[0046] Initially, the slide plate 2 is located at the left end of the frame 1, and the push rod of the vertical drive member 21 is in a retracted state. When it is necessary to drill holes on the left and right ends of the wooden board, the transport drive member 14 is first started, and the transport drive member 14 drives the right crossbar 15 to rotate clockwise, driving the conveyor belt 4 to rotate clockwise, and then the wooden board is manually placed on the left end of the conveyor belt 4. At this time, the support plate 41 supports the wooden board, and the conveyor belt 4 drives the wooden board to the right.

[0047] When the wooden board moves to a position opposite to the push roller 7, the centering drive is started and the push rod of the guide drive is controlled to extend, and the guide drive pushes the guide plate 62 upward, causing the guide wheel 63 to slide upward, pushing the wooden board upward, thereby causing the wooden board to detach from the conveyor belt 4; when the centering drive is working, the two push rollers 7 slide toward each other, pushing the wooden board to a position opposite to the drill bit 33, and then the centering drive is controlled to drive the push roller 7 to slide in the opposite direction and control the guide plate 62 to slide downward through the guide drive, so that the wooden board falls back on the conveyor belt 4 and moves to the right with the conveyor belt 4.

[0048] When the wooden board slides to the drill bit 33 close to the second drilling unit, the transport drive 14 is manually closed, and the positioning drive 5 and the vertical drive 21 are started at the same time. The positioning drive 5 drives the pressure plate 51 to slide downward, pressing the pressure plate 51 on the wooden board to position the wooden board. The push rod of the vertical drive member 21 is extended to make the first adjustment plate 3 and the second adjustment plate slide downward, and when the drill bit 33 slides down to the same height as the end of the wooden board, the vertical drive member 21 is closed and the first adjustment drive member, the second adjustment drive member and the drilling drive member are started, so that the drill bit 33 approaches the wooden board laterally and drills the wooden board. After the drilling is completed, the drill bit 33 is moved laterally away from the wooden board by the first adjustment drive member and the second adjustment drive member, and the drilling drive member is closed after the drill bit 33 completely leaves the wooden board, and the vertical drive member 21 and the positioning drive member 5 are controlled to make the mounting seat 32 slide upward and the pressure plate 51 slide upward. At the same time, the first adjustment drive member and the second adjustment drive member are controlled to reset the mounting seat 32, and the transport drive member 14 is started to continue to slide the wooden board to the right to the next process.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
