It should be noted that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as there is no conflict between them.

[0027] A plate punching device for furniture production, such as Figure 1 , Figure 3 and Figure 4As shown, it includes a base frame 1, a three-axis linear module 2 arranged on the upper part of the base frame 1, and a punching mechanism 3 installed on the moving end of the three-axis linear module 2. The three-axis linear module 2 is controlled to drive the punching mechanism 3 to move and adjust the position in the front-back and left-right directions, and to move in the up-down direction to punch holes, so as to realize the multi-directional punching operation; the moving end of the three-axis linear module 2 is slidably provided with a dust cover 33 surrounding the punching mechanism 3, and the dust cover 33 will synchronously contact with the plate as the punching mechanism 3 moves downward, so as to surround the punching position when punching to avoid debris and dust splashing and affecting the working environment. A spring 34 is connected between the dust cover 33 and the moving end of the three-axis linear module 2. When the moving end of the three-axis linear module 2 continuously drives the punching mechanism 3 to move downward for punching, the spring 34 is also driven to move downward and deform to squeeze the dust cover 33 against the upper side of the plate, which not only ensures the sealing effect of the dust cover 33 and the plate in close contact, but also provides a certain stable pressing force; the upper side of the bottom frame 1 is connected to two guide rails 4 located under the punching mechanism 3, which are opposite to each other and are both L-shaped. The guide rails 4 are arranged in the left and right directions, and the horizontal parts of the two guide rails 4 are used. The front and rear ends of the plate are supported, and the vertical parts of the two guide rails 4 are used to limit the plate in the front and rear directions; a chip discharge port located below the punching mechanism 3 is opened in the middle of the base frame 1, and a collecting frame 51 located below the chip discharge port is slidably provided at the lower part of the base frame 1. The collecting frame 51 is used to collect the debris dropped from the lower side of the plate during punching. The collecting frame 51 can be removed by moving it to the right to deal with the collected debris. A covering frame 52 for contacting the lower side of the plate is connected to the chip discharge port of the base frame 1, and the upper side of the covering frame 52 is flush with the upper side of the horizontal part of the guide rail 4, so that when the plate is When the plate is placed on the guide rail 4 for punching, the covering frame 52 will surround the lower side of the plate to prevent dust. The lower part of the covering frame 52 is slid with a guide frame 53 suitable for extending into the collection frame 51. After the collection frame 51 is placed, the guide frame 53 is moved down and extended into the collection frame 51 to further guide the debris and dust to fall into the collection frame 51, thereby cooperating with the dust cover 33 to prevent dust from falling on the upper and lower sides of the plate at the same time, and the guide frame 53 limits the collection frame 51 to avoid displacement of the collection frame 51. If the collection frame 51 needs to be removed, the guide frame 53 can be moved up.

[0028] like Figure 2As shown, the three-axis linear module 2 includes two front-to-rear opposite guide frames 21 connected to the upper middle part of the base frame 1, an electric screw 22 is installed on the guide frame 21, and the electric screw 22 is threadedly connected to a slide post 23 sliding on the guide frame 21, and the electric screw 22 is controlled to drive the slide post 23 to move left and right along the guide frame 21, and an electric guide rail 24 is installed on the slide post 23, and a guide beam 25 is connected between the sliders of the two electric guide rails 24, and the electric guide rail 24 is controlled to drive the guide beam 25 to move up and down, and a guide beam 25 is A rack 26 is connected to the side, and a slide 27 constituting the moving end of the three-axis linear module 2 slides on the guide beam 25. An electric gear 28 meshing with the rack 26 is installed on the upper side of the slide 27. The electric gear 28 is controlled to rotate and mesh with the rack 26, so that the slide 27 drives the punching mechanism 3 to move forward and backward along the guide beam 25 to adjust the position, and the slide column 23 can drive the slide 27 to drive the punching mechanism 3 to move left and right to adjust the position through the guide beam 25, and the guide beam 25 can drive the punching mechanism 3 to move up and down through the slide 27 to punch holes.

[0029] like Figure 2 As shown, the punching mechanism 3 includes a driving motor 31 installed on the slide 27, and the output shaft of the driving motor 31 rotates and passes through the dust cover 33. The end of the output shaft of the driving motor 31 is installed with a punching drill bit 32 located in the dust cover 33. The driving motor 31 is controlled to drive the punching drill bit 32 to rotate for punching. The lower side of the punching drill bit 32 is higher than or flush with the lower side of the dust cover 33. In this embodiment, the lower side of the punching drill bit 32 is higher than the lower side of the dust cover 33. When the dust cover 33 moves down to pre-cover the plate, the punching drill bit 32 will start to punch holes in the plate.

[0030] like Figure 3 and Figure 4 As shown, the bottom frame 1 also includes two electric guide rails 61 installed front and back opposite to each other, and an L-shaped crossbeam 62 is connected between the sliders of the two electric guide rails 61.

During the punching process, the electric guide rail 61 is controlled to drive the crossbeam 62 to drive the push plate 63 to move right and push the plate to the bottom of the punching mechanism 3 for punching. The driving beam 61 drives the push plate 63 to move left and reset, so as to prepare for the placement of the next plate when punching. After the punching of the previous plate is completed, the electric guide rail 2 61 continues to control the driving beam 62 to drive the push plate 63 to move right and push the next plate to the bottom of the punching mechanism 3. The next plate will push the previous punched plate to the right end of the guide track 4, so that the operator does not need to take and place the plate under the punching mechanism 3, which improves the safety of the operator taking and placing the plate; after the last plate is punched, stop the machine and remove the last plate.

[0031] like Figure 5 and Figure 6 As shown, it also includes a spring 2 54 connected between the guide frame 53 and the cover frame 52. The spring 2 54 is used to allow the downwardly moved guide frame 53 to move upward and reset. Two front and rear opposite wedge blocks 1 55 are connected to the guide frame 53. The guide frame 53 is driven to move downward and extend into the collection frame 51 through the wedge blocks 1 55. When the wedge blocks 1 55 are released, the guide frame 53 moves upward and resets under the action of the spring 2 54. One side of the crossbeam 62 is connected to two front and rear opposite connecting rods 64 that slide on the bottom frame 1. The two connecting rods 64 are connected to a push rod 1 65 suitable for squeezing the wedge blocks 1 55 on the sides close to each other. Figure 5 During the punching operation, the push rod 65 will continue to squeeze the wedge block 55, so as to guide the frame 53 to continue to extend into the collection frame 51. When the last plate is punched, the electric guide rail 61 is controlled to drive the crossbeam 62 to drive the push plate 63 to continue to move right to push the last plate to the right end of the guide track 4. During this process, the crossbeam 62 will also drive the push rod 65 to continue to move right through the connecting rod 64 until the wedge block 55 is released, and then the collection frame 51 can be automatically unlocked for picking and placing after the punching is completed.

[0032] like Figure 4 As shown, there is also a roller group 41 arranged at the right end of the guide track 4, and the roller group 41 is used to assist in moving the punched plate, so as to facilitate the operation of removing the plate.

The plates are stacked and placed in the material unloading frame 7, and the bottom plate will move down and fall between the two guide rails 4. At this time, the electric guide rail 2 61 is controlled to drive the cross beam 62 to drive the push plate 63 to move right, so that the bottom plate can be pushed to the bottom of the punching mechanism 3. A gap unloading mechanism is provided on the material unloading frame 7, and the gap unloading mechanism is used to control the corresponding frequency of unloading the plates in the material unloading frame 7 according to the number of reciprocating movements of the push plate 63, so that the new bottom plate on the material unloading frame 7 can fall onto the guide rail 4 after the push plate 63 moves left and resets.

[0034] like Figure 4 , Figure 7 and Figure 8The cam 72 is provided with a plurality of stop plates 71 arranged in a left and right manner at the bottom of the loading frame 7, and each stop plate 71 has three stop plates 71. When the push plate 63 moves rightward, the stop plate 71 pushes the bottom plate to move downward, and the stop plate 71 is moved downward to the bottom of the loading frame 7. The first clamping force 72 of the spring 72 is greater than that of the first clamping force 72 of the spring 72. The spring 72 of the spring 72 is greater than that of the first clamping force 72 of the spring 72. The spring 72 of the spring 72 is greater than that of the first clamping force 72 of the spring 72. The spring 72 of the spring 72 is greater than that of the first clamping force 72 of the spring 72. The wedge rod 73 will drive the baffle plate 71 to be retracted through the connecting rod until all the baffle plates 71 are retracted, the push plate 63 moves left to be reset, and then the next plate falls.

[0035] like Figure 4 , Figure 8 and Fig. 9As shown, it also includes two front and rear sliding frames 81 slidably arranged on the base frame 1. The upper side of the sliding frame 81 is connected to a pressure block 82 located above the guide track 4. When the plate moves to the bottom of the punching mechanism 3, the sliding frame 81 drives the pressure block 82 to move down to press and fix the plate, thereby improving the stability of the plate when punching. A spring 4 83 is connected between the sliding frame 81 and the base frame 1 for moving the downward pressure block 82 upward and resetting. A wedge block 2 84 is connected to the lower side of the sliding frame 81. The two connecting rods 64 are connected to a push rod 2 85 suitable for squeezing the wedge block 2 84 on the side away from each other.

The second wedge block 84 will drive the pressure block 82 to move down through the sliding frame 81 to fix the plate previously pushed to the bottom of the punching mechanism 3 by the push plate 63, thereby automatically fixing it. At this time, the three-axis linear module 2 can drive the punching mechanism 3 to punch holes in multiple positions without loosening the plate. When the crossbeam 62 pushes the plate 63 to the right to push a new plate, the crossbeam 62 will also drive the second push rod 85 to move right through the connecting rod 64 to loosen the wedge block 84. The sliding frame 81 will move up under the resetting action of the spring four 83 to loosen the punched plate, thereby facilitating the replacement of the plate. The feeding and loosening steps of the plate are interrelated and coordinated with each other.
