Description

Technical Field

[0001] The present invention relates to the technical field of deburring equipment, specifically an automatic deburring equipment. Background Art

[0002] At present, many products (such as plastic shells, etc.) are processed and formed by molds. Due to the errors or wear of the molds, residues or particles will be generated on the edges of the products. These residues or particles are usually called burrs, and the edges with burrs can be called burr edges.

[0003] Therefore, in order to remove the burr edges, there is deburring equipment. The current deburring equipment has the following problems: 1. The current deburring equipment is not equipped with a safety door, resulting in some burrs flying around during the removal process, splashing to the surroundings, making it inconvenient for later cleaning and also unsafe; 2. After the current deburring equipment removes one side, during the process of removing the burrs at the bottom of the product, it is necessary for workers to flip the product manually and then further remove the burrs, resulting in low work efficiency and the entire operation is also unsafe; 3. Due to the layout problem of the current deburring equipment, it is difficult to process large workpieces; 4. Difficult waste recycling. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic deburring equipment to overcome the problems of low work efficiency, unsafe use, and difficult waste recycling of the existing equipment.

[0005] To achieve the above object, the present invention provides the following technical solution: An automatic deburring device, including a frame, on which there is a waste recycling funnel with a downwardly inclined bottom. The bottom plate of the waste recycling funnel is inclined, and there is a discharge port at the low end of the bottom plate of the waste recycling funnel. On the frame, there is a pull-out waste recycling drawer, the upper part of which is communicated with the discharge port. Above the waste recycling funnel, there is a product fixture. The product fixture includes two C-shaped first mounting brackets fixed on the frame, and the two first mounting brackets are respectively located on both sides of the waste recycling funnel. Between each pair of first mounting brackets, there is a first connecting plate rotatably connected by a first rotating shaft. A second connecting plate located above the waste recycling funnel is fixed between the two first connecting plates. The center of the second connecting plate is a through-hole structure. Around the upper part of the second connecting plate, there are product fixture heads. On one of the first rotating shafts, there is a first motor for driving the rotation of the first rotating shaft. On the frame, there is a first guide rail connected to the rear end of the waste recycling funnel. A first slider is slidably connected to the first guide rail. On the frame, there is a driving mechanism for driving the first slider to move within the first guide rail. A six-axis deburring robot capable of horizontally sliding on the first guide rail is fixed on the first slider. On the frame, there is a C-shaped safety fence surrounding all the products on the frame. Four sliding rail push-pull doors capable of sliding into the C-shaped safety fence are slidably connected to the notch of the C-shaped safety fence. The four sliding rail push-pull doors are arranged in pairs and opened in opposite directions, and the side door can be hidden inside another door. When all the four sliding rail push-pull doors are closed, they can be combined with the C-shaped safety fence to form a closed structure.

[0006] Further, to achieve automated operation, there is a second guide rail on the inner side above and below the notch of the C-shaped safety fence. Below the upper cross plate of the sliding rail push-pull door, there is a third connecting plate. Below the vertical plate of the sliding rail push-pull door, there is a fourth connecting plate. Above the third connecting plate, there is a third slider slidably connected to the second guide rail. Above the fourth connecting plate, there is a fourth slider slidably connected to the second guide rail. And two of the third connecting plates are located on the left side of the notch of the C-shaped safety fence, and the other two third connecting plates are located on the right side of the notch of the C-shaped safety fence. On each of the third connecting plates on the left and right sides close to the center of the notch, there is a push plate fixed, and two push plates are located on the third connecting plates on the left and right sides close to the center of the notch. On each push plate, there is a first cylinder for driving the push plate to move towards both sides.

[0007] Further, to facilitate the pressing action on different products, the product fixture head includes a fixed seat fixed on the second connecting plate. A pressing block is connected to the fixed seat by screws. Below the pressing block, there is a silicone pressing head. A guide rod is arranged on the side of the through-hole structure of the second connecting plate.

[0008] Furthermore, for convenient movement, placing feet are provided around the bottom of the frame, and sliding rollers are rotatably connected to the sides of the placing feet.

[0009] In order to facilitate positioning, positioning plates are provided on both sides of the first guide rail.

[0010] In order to facilitate observation, observation windows are provided on each sliding rail sliding door.

[0011] Compared with the prior art, through the above structural design, deburring operations can be carried out on the bottom (hollow design under the fixture), the front lower edge, and the side of the workpiece, so that the equipment can perform deburring without dead angles on the space to be operated, achieving true automation. In addition, the C-shaped safety fence 17 is provided above, and the automated double-leaf door design avoids the problem of waste flying everywhere during the processing. Therefore, the present invention has the following advantages: 1. During the processing, burrs will not fly everywhere, making the later cleaning convenient and the use safer; 2.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to the following embodiments for further description of the present invention:

[0026] Example 1:

[0027] As Figures 1-10As shown in the figure, an automatic deburring device provided in this embodiment includes a frame 1. A waste recycling funnel 2 with a downwardly inclined bottom is provided on the frame 1. The bottom plate of the waste recycling funnel 2 is inclined. An outlet 3 is provided at the lower end of the bottom plate of the waste recycling funnel 2. A pull-out waste recycling drawer 4 is provided on the frame 1. The upper part of the waste recycling drawer 4 communicates with the outlet 3. A product fixture 5 is provided above the waste recycling funnel 2. The product fixture 5 includes two C-shaped first mounting brackets 6 fixed on the frame 1, and the two first mounting brackets 6 are respectively located on both sides of the waste recycling funnel 2. A first connecting plate 8 is rotatably connected between each pair of first mounting brackets 6 through a first rotating shaft 7. A second connecting plate 9 located above the waste recycling funnel 2 is fixed between the two first connecting plates 8. The center of the second connecting plate 9 is a through-hole structure 11. Product fixture heads 12 are provided around the upper part of the second connecting plate 9. A first motor 13 for driving the first rotating shaft 7 to rotate is connected to one of the first rotating shafts 7. A first guide rail 14 is connected to the frame 1 at the rear end of the waste recycling funnel 2. A first slider 15 is slidably connected to the first guide rail 14. A driving mechanism 35 for driving the first slider 15 to move in the first guide rail 14 is provided on the frame 1. A six-axis deburring robot 16 capable of horizontally sliding on the first guide rail 14 is fixed on the first slider 15. A C-shaped safety fence 17 that encloses all the products on the frame 1 is provided on the frame 1. Four sliding rail push-pull doors 18 that can slide into the C-shaped safety fence 17 are slidably connected to the notch 17-3 of the C-shaped safety fence 17. The four sliding rail push-pull doors 18 are arranged in pairs and opened in opposite directions, and the structure is such that one side door can be hidden inside the other door. When all four sliding rail push-pull doors 18 are closed, they can be combined with the C-shaped safety fence 17 to form a closed structure.

[0028] In this embodiment, the C-shaped safety fence 17 is assembled by multiple steel bars 17-1 and steel plates 17-2.

[0029] In this embodiment, the driving mechanism 35 includes a second motor 35-1 located on the side of the first slider 15. A gear 35-3 is connected to the output shaft of the second motor 35-1. A linear rack 35-2 is fixed on the side of the first slider 15. The gear 35-3 meshes with the linear rack 35-2. The second motor 35-1 is connected to the first slider 15 through a fixed connection frame 35-4. During operation, when the second motor 35-1 works, it drives the gear 35-3 to rotate. At this time, the gear 35-3 can move horizontally within the linear rack 35-2, and finally drives the fixed connection frame 35-4 to move synchronously. During the movement of the fixed connection frame 35-4, it drives the first slider 15 to move horizontally on the first guide rail 14, and finally adjusts the horizontal movement process of the six-axis deburring robot 16 to ensure that the six-axis deburring robot 16 can perform the deburring process on products of different lengths. Therefore, the above-mentioned gear-rack transmission can perform left and right movement, and this design can greatly increase the operating radius of the industrial robot, making it possible to process large workpieces and at the same time solving the deburring difficulty on both sides of the workpiece.

[0030] Further, in order to achieve automatic operation, a second guide rail 10 is provided on the inner side above and below the notch 17-3 of the C-shaped safety fence 17. A third connecting plate 20 is provided below the upper cross plate 19 of the sliding rail sliding door 18. A fourth connecting plate 22 is provided below the vertical plate 21 of the sliding rail sliding door 18. A third slider 23 that is slidably connected to the upper second guide rail 10 is provided above the third connecting plate 20. A fourth slider 24 that is slidably connected to the lower second guide rail 10 is provided above the fourth connecting plate 22. And two of the third connecting plates 20 are located on the left side of the notch 17-3 of the C-shaped safety fence 17, and the other two third connecting plates 20 are located on the right side of the notch 17-3 of the C-shaped safety fence 17. A pushing plate 25 is fixed on each of the third connecting plates 20 on the left and right sides, and the two pushing plates 25 are located on the third connecting plates 20 on the left and right sides close to the center of the notch 17-3. A first cylinder 26 for driving the pushing plate 25 to move to both sides is provided on each pushing plate 25.

[0031] In this embodiment, the specific structure of the four sliding rail sliding doors 18 that are opened in pairs is as follows: Two first door panels 18-1 and second door panels 18-2 that can be pulled apart and spliced together (as shown in Figure 2 ), and become a single door panel after overlapping are provided on both the left and right sides. And the first door panel 18-1 on the left side and the first door panel 18-1 on the right side are opened in pairs, and the second door panel 18-2 on the left side and the second door panel 18-2 on the right side are opened in pairs. At the same time, a pushing plate 25 is fixed on the third connecting plate 20 on both first door panels 18-1. At the same time, when the two first door panels 18-1 are opened, they can overlap with the second door panel 18-2 up and down to form the form of a single door (as shown in Figure 7As shown in the figure, when all four sliding-rail sliding doors 18 are closed, the gap 17-3 of the C-shaped safety fence 17 can be sealed. Through the above structural design, the problem of low space utilization rate in the existing double-door design is solved, and finally automatic door opening and closing can be realized.

[0032] Furthermore, in order to facilitate the pressing of different products, the product fixture head 12 includes a fixed seat 27 fixed on the second connecting plate 9. A pressing block 28 is connected to the fixed seat 27 by screws. A silicone pressing head 29 is provided below the pressing block 28. A guide rod 30 is provided on the side of the through-hole structure 11 of the second connecting plate 9. During operation, the guide rod 30 is used for guiding. The product is placed above the through-hole structure 11, and the screws on the rotating pressing block 28 are used to press the four sides of the product respectively to fix the product.

[0033] Furthermore, for easy movement, placing feet 31 are provided around the bottom of the frame 1, and sliding rollers 32 are rotatably connected to the sides of the placing feet 31.

[0034] In order to facilitate limiting, limiting plates 33 are provided on both sides of the first guide rail 14. By setting the limiting plates 33, the first slider 15 is prevented from moving to both sides.

[0035] In order to facilitate observation, observation windows 34 are provided on each sliding-rail sliding door 18. By setting the observation windows 34, it is convenient to check the internal situation.

[0036] During operation, first install the product 36 to be deburred on the product fixture 5, and then drive the six-axis deburring robot 16 to work. The driving mechanism 35 is used to adjust the left and right movement positions of the six-axis deburring robot 16. Finally, the two sides of the product are processed for deburring. At the same time, by driving the first motor 13 to work, the second connecting plate 9 can be driven to rotate above the waste recycling funnel 2, and finally the bottom of the product is turned upwards, which is convenient for the six-axis deburring robot 16 to perform deburring processing on the bottom of the product. In addition, the waste generated during processing directly enters the waste recycling drawer 4 through the discharge port 3. Later, the waste can be conveniently and quickly collected by pulling out the waste recycling drawer 4. Therefore, through the above structural design, deburring operations can be performed on the bottom (hollow design under the fixture), the front lower edge, and the side of the workpiece, so that the equipment can perform deburring on the space to be operated without dead angles, realizing true automation. In addition, the C-shaped safety fence 17 is provided above, and the automatic double-door design can avoid the problem of waste flying during the processing. Therefore, the present invention has the following advantages: 1. During the processing, the burrs will not fly around, making the later cleaning convenient and the use safer; 2. Realize automatic flipping of the product, improve work efficiency, and have better deburring effect; 3. It is relatively convenient for processing large parts; 4. The waste recycling is more convenient and fast.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, in all respects, the embodiments should be regarded as exemplary and non-restrictive.
