Description

Technical Field

[0001] This utility model relates to the field of drilling technology, and in particular to an automatic drilling device for wooden display cases. Background Technology

[0002] The development of wooden display cases can be traced back to China's economic reform and opening-up period in the 1970s. At that time, with the increasing demand for display products in the Chinese market, traditional counters could no longer meet the needs of enterprises for display and sales, so wooden display cases quickly emerged. Over time, the design and manufacturing level of wooden display cases have continuously improved, evolving from a simple and unadorned appearance to one that places greater emphasis on functionality and aesthetics, thus meeting the display needs of different industries.

[0003] When processing wooden display cabinet panels, it is necessary to drill holes along the edges of the panels to facilitate subsequent splicing. At the same time, the position needs to be fixed during drilling. For example, a drilling device for display cabinets announced by patent number CN217573258U can perform double-sided drilling and has a top pressing effect. However, in this solution, there is no effective limitation on the perimeter of the panel. During the drilling process, it is easy to cause horizontal displacement due to vibration. Moreover, after each drilling, the position needs to be manually pushed, which is very troublesome and easy to misalign, affecting the processing accuracy and efficiency.

[0004] Therefore, the applicant proposed an automatic drilling device specifically for wooden display cases to solve the problem. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example 1, by Figures 1-6The present invention includes a device platform 1. Two long plates 10 are fixed to the top of the device platform 1, and a U-shaped frame 11 is mounted on their top surfaces. A hydraulic rod 12 is mounted on the top of the U-shaped frame 11, and the hydraulic rod 12 connects to a lifting plate 13. The lifting plate 13 slides inside the U-shaped frame 11, and two electric drill bits 14 are symmetrically mounted on its bottom. A workpiece table 3 is moved and mounted on the top of the device platform 1 via a drive assembly 2. A stop plate 31 is mounted on one end of the top of the workpiece table 3. A clamping assembly 4 is connected to the inner side of the long plates 10 of the workpiece table 3. The clamping assembly 4 includes a clamping plate 4 located at the top of the workpiece table 3. 1. Two clamping plates 41 are provided on each side of the workpiece table 3. The bottom of the clamping plate 41 is connected to the slider 42 via a connecting rod. The connecting rod slides in the opening of the workpiece table 3. The slider 42 slides outside the fixed rod 45 between the two support plates at the bottom of the workpiece table 3. The slider 42 is connected to a support plate by a spring 411. The bottom of the slider 42 is rotatably mounted with a pulley 43. The pulley 43 rolls on the side of the slide plate 44 fixed inside the long plate 10. The contact surface between the slide plate 44 and the pulley 43 forms two slides at different horizontal positions through an inclined plane.

[0026] As described above, through the design of the clamping component 4, during processing, the wooden display cabinet board is placed on the workpiece table 3 using a robotic suction cup, with one end abutting the backing plate 31 to maintain a correct position for easy clamping. This end is also adjacent to the clamping plates 41 on both sides. Then, the drive component 2 drives the workpiece table 3 to move horizontally and linearly, eventually moving it to a suitable drilling position below the U-shaped frame 11. During this process, the pulley 43 slides along the side of the slide plate 44. When the pulley 43 passes the inclined surface of the slide plate 44, it will... Move to the inner side of the slide plate 44, so that the slider 42 is squeezed and moved, and the spring 411 is stretched, which drives the two clamping plates 41 to move towards the center of the workpiece table 3, and finally clamps the two sides of the cabinet plate. When it moves to the grinding position, all the clamping plates 41 are firmly clamped. Then start the electric drill bit 14, and then start the hydraulic rod 12 to drive the lifting plate 13 to descend. The electric drill bit 14 contacts the plate to complete the drilling. Then, the plate is moved at a fixed distance by the drive component 2 to drill holes at equal intervals.

[0027] Two clamping plates 41, which are away from the abutment plate 31, are connected to inclined blocks 46 by L-shaped rods. The inclined surface of inclined block 46 fits with the inclined surface of inclined block 47. Inclined block 47 is fixed to the back of clamping plate 48. A slider 49 is fixed to the bottom of clamping plate 48. Slider 49 slides in the open slide at the top of the workpiece table 3. Slider 49 is connected to spring 410 inside the slide. Clamping plate 48 is located directly opposite the abutment plate 31.

[0028] In terms of further optimization of the clamping operation, when the two opposite clamping plates 41, which are far away from the abutment plate 31, are clamped, the inclined block 46 on its side will also move. Through the fit of the inclined plates, the inclined block 47 is pressed to move. The inclined block 47 can push the clamping plate 48. The slider 49 slides against the elastic force of the spring 410. When the clamping plate 41 clamps the board, the clamping plate 48 clamps the last side of the cabinet board. That is, the clamping plate 48, the clamping plate 41 and the abutment plate 31 clamp the four sides of the board. Note that at this time the board moves to the initial drilling position.

[0029] Two vertical rods 17 are slidably connected to the lifting plate 13. The top of the vertical rods 17 is connected to the lifting plate 13 by a spring 15. A protective cover 16 is installed at the bottom of the vertical rods 17. The protective cover 16 has an opening through which the electric drill bit 14 passes. It should be noted that the electric drill bit 14 is an existing technology product, consisting of a motor and a drill bit. The opening on the protective cover 16 is passed through by the motor and is close to it. The shape of the opening can be adjusted according to the shape of the motor, and it can be square or round. There is no limitation here. The bottom of the protective cover 16 slightly exceeds the bottom of the electric drill bit 14.

[0030] In the optimized drilling design, during drilling, the protective cover 16 descends with the lifting plate 13 and first contacts the surface of the plate. Then, the lifting plate 13 and the electric drill bit 14 continue to descend, while the protective cover 16 remains stationary. However, the two vertical rods 17 slide through the lifting plate 13, and the spring 3 15 is stretched. After drilling is completed, the protective cover 16 resets. In this way, the protective cover 16 not only has a pressing effect, but also intercepts the flying debris generated by the electric drill bit 14 during drilling, providing excellent protection. Note that the top of the vertical rods 17 can pass through the top opening of the U-shaped frame 11.

[0031] Rubber pads are bonded to the contact surfaces of clamping plate 41, abutment plate 31, clamping plate 48, and protective cover 16 with the workpiece.

[0032] Furthermore, rubber pads can provide cushioning during contact compression or clamping, making them suitable for wood-based panels and highly practical.

[0033] Depend on Figure 6 As shown, there are two opening slots on one side of the workpiece table 3, and a dust collection box 32 is inserted into the opening slot. The top surface of the dust collection box 32 is provided with a row of dust guiding holes, and the dust guiding holes correspond to the positions of the holes drilled in the workpiece. The front of the dust collection box 32 is fixedly installed to the workpiece table 3 by bolt plate 33 and bolts. The bolt plate 33 is installed horizontally and fits against the front of the dust collection box 32 and the front of the workpiece table 3.

[0034] During processing, if the drilling is for connecting and fixing the various parts of the display case structure, such as installing hinges, handles, and support plates, then the holes usually need to be drilled through to install screws or other fasteners. In this case, the dust guide holes on the top surface of the dust collection box 32 are designed according to the actual drilling spacing and number. When the drill bit passes through the board, it also passes through the dust guide holes and enters the interior of the dust collection box 32, allowing some debris to enter the dust collection box 32. After a period of time, the dust collection box 32 can be removed and the debris and dust inside can be emptied. Note that if the holes are not drilled through, the dust collection box 32 does not need to be installed.

[0035] The drive assembly 2 includes a lead screw 21 rotatably mounted between the top support plates of the device platform 1. The lead screw 21 is threadedly connected to the bottom protrusion 22 of the workpiece table 3. Two rows of moving wheels 24 are rotatably mounted on the bottom of the protrusion 22. The moving wheels 24 roll on the surface of the device platform 1. A drive motor 23 that connects to the lead screw 21 is mounted on the side wall of one of the support plates at the top of the device platform 1. The shaft of the drive motor 23 is connected to the rotating shaft of the lead screw 21.

[0036] With the design of drive component 2, when the workpiece table 3 is moved for automatic feeding, the drive motor 23 is started to drive the lead screw 21 to rotate, and the protrusion 22 can move through the moving wheel 24. After the drilling is completed, the workpiece table 3 is returned to its original position. The clamping plate 41 and clamping plate 48 can be restored by the spring 410 and spring 411. Then, the workpiece can be unloaded by the robotic arm suction cup in the prior art.

[0037] Working principle: The robotic suction cup 5 places the wooden display case board onto the workpiece table 3, with one end of it adhering to the backing plate 31. The drive assembly 2 is activated, driving the workpiece table 3 to move horizontally and linearly to the appropriate drilling position below the U-shaped frame 11. During this process, the clamping plate 41 of the clamping assembly 4 slides on the slide plate 44 via the pulley 43. When the pulley 43 passes the inclined surface of the slide plate 44, it moves to the inner side of the slide, causing the slider 42 to be squeezed and moved, stretching the spring 411, which drives the two clamping plates 41 on both sides to move towards the center of the workpiece table 3, and finally clamps the two sides of the board. At the same time, the two clamping plates 41 away from the backing plate 31 are clamped by the inclined block 46 and the inclined block 4. The engagement of component 7 pushes clamping plate 2 48 to hold the last side of the plate, forming a four-sided clamping. Then, hydraulic rod 12 drives lifting plate 13 to descend, allowing electric drill bit 14 to pass through protective cover 16 and contact the plate to complete drilling. During this process, protective cover 16 first contacts the plate surface, providing a pressing effect and intercepting flying debris generated during drilling. Vertical rod 17 slides and interweaves on lifting plate 13, and spring 3 15 is stretched. After drilling, it resets, and hydraulic rod 12 drives lifting plate 13 to rise, moving the plate to the next drilling position. This process repeats. After drilling, drive assembly 2 returns workpiece table 3 to its original position, and clamping assembly 4 resets via spring 2 410 and spring 1 411. Finally, the material is unloaded via robotic suction cup 5, completing the entire processing.
