Description

Technical Field

[0001] This application relates to the field of television equipment processing technology, and in particular to an automatic cutting machine for television frame blanks. Background Technology

[0002] After the TV frame is injection molded, sprue residue corresponding to the gate will remain on its surface. This sprue needs to be removed before subsequent processing steps such as painting and laser engraving. Currently, the industry commonly uses manual methods to remove sprue. That is, after the frame injection molding is completed and the material is unloaded, workers place it on an operating table and remove the sprue by manually breaking it off or cutting it with a tool.

[0003] This method is not only inefficient and difficult to meet the needs of mass production, but also prone to material loss due to worker fatigue or negligence during manual operation, which affects the quality of subsequent processing and needs improvement. Utility Model Content

[0004] To automate the removal of TV frame stubs, this application provides an automatic cutting machine for TV frame stubs.

[0005] This application provides an automatic cutting machine for television frame blanks, which adopts the following technical solution:

[0006] An automatic cutting machine for TV frame trimmings includes a base and a placement frame for placing the frame. The placement frame is provided with limiting posts for positioning the frame. Multiple limiting posts are arranged in a rectangular shape. The base has a clamping mechanism for pressing the frame and a cutting mechanism for cutting off the trimmings from the frame. The base has a discharge port for the cut trimmings to fall through. The base also has a waste collection mechanism for collecting the trimmings.

[0007] By adopting the above technical solution, and using the upper limit posts of the placement frame to form a rectangle, the operator can quickly and accurately position the face frame on the placement frame and use the clamping mechanism to clamp the face frame, ensuring the stability of the face frame during cutting. At the same time, the cutting mechanism can precisely control the cutting force and angle to cut the material head, reducing the occurrence of cracks or surface scratches on the face frame. This achieves automated cutting of the material head on the face frame, and the setting of the feeding port and waste collection mechanism enables automatic collection of the material head, greatly improving the material head removal efficiency.

[0008] Preferably, the clamping mechanism includes a clamping plate, a control cylinder, a pressure rod, a support base, and a connecting plate. One end of the pressure rod is hinged to the piston rod of the control cylinder, and the other end is fixedly connected to the clamping plate. The support base is mounted on the control cylinder. One end of the connecting plate is hinged to the pressure rod, and the other end is hinged to the support base. The clamping plate forms an abutment fit with the face frame.

[0009] By adopting the above technical solution, when one end of the control cylinder drives the pressure rod to move upward, the other end of the pressure rod drives the pressing plate to press down on the face frame, thereby ensuring that the pressing plate effectively presses the face frame.

[0010] Preferably, the cutting mechanism includes a first cutting unit and a second cutting unit. Multiple first cutting units are provided and spaced apart. The second cutting units are located at the four corners of the placement frame, and a clearance space is formed between the second cutting unit and the machine base to avoid the first cutting unit.

[0011] By adopting the above technical solution, and utilizing the arrangement of the first cutting unit and the second cutting unit, with the first cutting unit spaced apart and the second cutting unit located at the four corners of the placement frame and forming a clearance space, the cutting machine can simultaneously cut the material at different positions of the TV frame, especially achieving full coverage of the material at the edges and corners of the frame, avoiding missed cuts. At the same time, the clearance space design ensures that the first cutting unit and the second cutting unit do not interfere with each other during operation, improving cutting efficiency and comprehensiveness.

[0012] Preferably, the first cutting unit includes a first cylinder, a first connecting seat, a first cutter, and a first slide block. The piston rod of the first cylinder is connected to the first connecting seat, the first cutter is disposed on the first connecting seat, and the first connecting seat and the first slide block form a sliding engagement.

[0013] By adopting the above technical solution, the first cylinder drives the first connecting seat to move the first cutter along the first slide block, thereby realizing the automation and precise control of the cutting action. The setting of the first slide block ensures the stability of the movement trajectory of the first cutter, making the cutting position more accurate, reducing the damage to the face frame caused by cutter shaking, and improving the accuracy and stability of material cutting.

[0014] Preferably, the second cutting unit includes an extension frame, a second cylinder, a second connecting seat, a second cutter, and a second slide. The second cylinder is mounted on the extension frame, and the piston rod of the second cylinder is connected to the second connecting seat. The second cutter is mounted on the second connecting seat, and the second connecting seat and the second slide form a sliding engagement.

[0015] By adopting the above technical solution and using the heightening frame, the height of the second cylinder is increased, thereby raising the connection height between the piston rod of the second cylinder and the second connecting seat. The second cylinder drives the second cutter to slide along the second slide block, ensuring the stability and accuracy of the second cutter's cutting action. In conjunction with the first cutting unit, it further improves the cutting machine's adaptability to material heads in different positions and the cutting effect.

[0016] Preferably, the waste collection mechanism includes a waste collection bin and a guide plate for guiding the cut material head into the waste collection bin, the guide plate being inclined.

[0017] By adopting the above technical solution and utilizing the inclined guide plate, the material head falling from the discharge port can be smoothly guided into the waste collection box, realizing the automatic collection and centralized processing of the material head.

[0018] Preferably, the machine base is provided with a roller assembly for easy pushing and pulling of the waste collection box by the operator and a limiting plate for guiding the waste collection box to slide along the roller assembly. The limiting plate is provided on both sides of the waste collection box.

[0019] By adopting the above technical solution, the roller assembly inside the machine base makes it convenient for workers to push and pull the waste collection box, facilitating the timely cleaning and collection of fallen material heads. The limiting plate guides the waste collection box to slide along a limited trajectory, preventing the waste collection box from shifting its position during the pushing and pulling process, thus preventing material heads from falling out of the collection box.

[0020] Preferably, the bottom of the base is provided with swivel casters to facilitate the movement of the base by the operator.

[0021] By adopting the above technical solution and utilizing the universal casters, it is easy for workers to push or pull the machine base, and it is convenient to adjust the placement of the cutting machine in the workshop according to production needs.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting up a rectangle around the upper limit posts of the placement frame, the operator can quickly and accurately position the face frame on the placement frame and use the clamping mechanism to clamp the face frame, ensuring the stability of the face frame during cutting; at the same time, the cutting mechanism can precisely control the cutting force and angle to cut the material head, reducing the occurrence of cracks or surface scratches on the face frame, thus realizing the automated cutting of the material head on the face frame, and the setting of the feeding port and waste collection mechanism realizes the automatic collection of the material head, which greatly improves the material head removal efficiency;

[0024] 2. When the control cylinder drives one end of the pressure rod to move upward, with the hinge axis between the pressure rod and the connecting plate as the rotation axis, the other end of the pressure rod drives the pressing plate to press down on the face frame, thereby ensuring that the pressing plate effectively presses the face frame;

[0025] 3. By utilizing the arrangement of the first cutting unit and the second cutting unit, with the first cutting unit spaced apart and the second cutting unit located at the four corners of the placement frame and forming a clearance space, the cutting machine can simultaneously cut the material at different positions on the TV frame, especially achieving full coverage of the material at the edges and corners of the frame, avoiding missed cuts. At the same time, the clearance space design ensures that the first cutting unit and the second cutting unit do not interfere with each other during operation, improving cutting efficiency and comprehensiveness.

[0033] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail.

[0034] This application discloses an automatic cutting machine for television frame blanks.

[0035] Reference Figure 1 An automatic cutting machine for TV frame blanks includes a base 1 and a placement frame 2. The base 1 is hollow inside. The placement frame 2 is fixed to the top of the base 1 by bolts. The placement frame 2 is provided with limiting posts 21 for positioning the frame. At least four limiting posts 21 are provided and arranged in a rectangular shape. The multiple limiting posts 21 form a limiting area for limiting the frame. The lower end of any limiting post 21 is welded to the rectangular placement frame 2. The upper end of any limiting post 21 is a conical structure for forming a guiding abutment with the side wall of the frame, thereby achieving fast and accurate positioning of the frame.

[0036] Reference Figure 1 and Figure 2 The base 1 is equipped with a clamping mechanism 3 for clamping the face frame and a cutting mechanism 4 for cutting off the material head on the face frame. Multiple clamping mechanisms 3 and cutting mechanisms 4 are provided and are located inside the placement frame 2. The clamping mechanisms 3 and cutting mechanisms 4 are evenly distributed along the four sides of the placement frame 2, thereby achieving clamping at multiple positions on the face frame and enhancing the stability of the face frame during the cutting process.

[0037] Reference Figure 1 and Figure 2 The placement frame 2 is provided with a clearance groove 22 corresponding to the position and number of the cutting mechanism 4. The clearance groove 22 can avoid the cutting of the material head by the cutting mechanism 4. The base 1 is provided with a feeding port for the material head to fall down corresponding to the position and number of the clearance opening. The base 1 is provided with a waste collection mechanism 5 for collecting the material head.

[0038] Reference Figure 1 and Figure 2 The clamping mechanism 3 clamps the face frame, ensuring its stability during cutting. At the same time, the cutting mechanism 4 can precisely control the cutting force and angle to cut the material head, reducing the occurrence of cracks or surface scratches on the face frame. The material head cut off by the cutting mechanism 4 falls through the feeding port into the waste collection mechanism 5 inside the machine base 1 for collection and processing, thereby realizing the automated cutting and collection of material head on the face frame, greatly improving the material head removal efficiency.

[0039] Reference Figure 1 and Figure 2 Five clamping mechanisms 3 are spaced apart along the length of the placement frame 2, and six clamping mechanisms 3 are spaced apart along the width of the placement frame 2. In this embodiment, since the structure and connection method of each clamping mechanism 3 are the same, one clamping mechanism 3 will be used as an example for explanation.

[0040] Reference Figure 2 and Figure 3 The pressing mechanism 3 includes a pressing plate 31 and a driving unit 32 for driving the pressing plate 31 to press down on the face frame. The lower surface of the pressing plate 31 and the upper surface of the face frame form an abutment fit. The driving unit 32 includes a control cylinder 321, a pressing rod 322, a support seat 323 and a connecting plate 324. The control cylinder 321 is vertically fixed to the machine base 1 by bolts. One end of the pressing rod 322 is hinged to the piston rod of the control cylinder 321 through a rotating shaft, and the other end is fixed to the pressing plate 31 by bolts. The support seat 323 is fixed to the control cylinder 321 by bolts. One end of the connecting plate 324 is hinged to the pressing rod 322 through a rotating shaft, and the other end is hinged to the support seat 323 through a rotating shaft.

[0041] Reference Figure 2 and Figure 3 The pivot between the connecting plate 324 and the pressure rod 322 is located between the two ends of the pressure rod 322. When the control cylinder 321 drives the piston rod to move the pressure rod 322 upward, the pressure rod 322 rotates around the pivot between it and the connecting plate 324, causing the end of the pressure rod 322 away from the piston rod to drive the pressing plate 31 to press down on the face frame. This design can ensure that the pressing plate 31 can effectively press the face frame, and can also avoid deformation of the face frame due to excessive pressure, thus improving the reliability and safety of the pressing process.

[0042] Reference Figure 1 and Figure 4 The cutting mechanism 4 includes a first cutting unit 41 and a second cutting unit 42. Multiple first cutting units 41 are provided and are arranged at intervals. In this embodiment, five first cutting units 41 are arranged at intervals along the length and width directions of the placement frame 2, that is, twenty first cutting units 41 are provided. The second cutting units 42 are arranged at the four corners of the placement frame 2.

[0043] Reference Figure 2 and Figure 4 The second cutting unit 42 and the base 1 form a clearance space for avoiding the first cutting unit 41, and the second cutting unit 42 and the first cutting unit 41 located in the clearance space are arranged perpendicular to each other, ensuring that the first cutting unit 41 and the second cutting unit 42 do not interfere with each other when working.

[0044] Reference Figure 2 and Figure 4 By utilizing the first cutting unit 41 and the second cutting unit 42, the material scraps at different positions of the TV frame can be cut, especially the material scraps at the edges and corners of the frame, to achieve full coverage and avoid missing material scraps. In this embodiment, since the structure and connection method of each first cutting unit 41 are the same, one of the first cutting units 41 will be used as an example for explanation.

[0045] Reference Figure 2and Figure 5 The first cutting unit 41 includes a first cylinder 411, a first connecting seat 412, a first cutter 413, and a first slide 414. The first cylinder 411 and the first slide 414 are both fixed to the machine base 1 by bolts. The first cylinder 411 is horizontally arranged. The piston rod of the first cylinder 411 is horizontally connected to the first connecting seat 412 by a coupling. The first cutter 413 is horizontally fixed to the first connecting seat 412 by bolts. The first connecting seat 412 and the first slide 414 form a sliding fit through a slide rail.

[0046] Reference Figure 2 and Figure 5 In use, the first cylinder 411 drives the first connecting seat 412 to move the first cutter 413 along the first slide block 414, realizing the automation and precise control of the cutting action. The first connecting seat 412 is slidably set on the first slide block 414, which ensures the stability of the movement trajectory of the first cutter 413, makes the cutting position more accurate, reduces the damage to the face frame caused by the wobbling of the cutter, and improves the accuracy and stability of the material head cutting.

[0047] Reference Figure 2 and Figure 5 A protective cover 415 is provided above the first connecting seat 412 and the first cutter 413. The protective cover 415 is fixed to the machine base 1 by bolts. With the setting of the protective cover 415, the protective cover 415 can effectively block the debris from flying outward, avoid the debris from injuring the operator, and improve the safety of equipment operation.

[0048] Reference Figure 2 and Figure 4 Since the four second cutting units 42 have the same structure and connection method, we will now take one of the second cutting units 42 as an example for explanation.

[0049] Reference Figure 2 and Figure 4 The second cutting unit 42 includes an extension frame 421, a second cylinder 422, a second connecting seat 423, a second cutter 424, and a second slide 425. The extension frame 421 and the second slide 425 are fixed to the machine base 1 by bolts. The second cylinder 422 is fixed to the extension frame 421 by bolts. The piston rod of the second cylinder 422 is horizontally connected to the second connecting seat 423 by a coupling. The second cutter 424 is horizontally fixed to the second connecting seat 423 by bolts. In use, the second cylinder 422 drives the second cutter 424 to slide along the second slide 425. The second connecting seat 423 and the second slide 425 form a sliding engagement through a slide rail, ensuring the stability and accuracy of the cutting action of the second cutter 424.

[0050] Reference Figure 4 and Figure 5By using the heightening bracket 421, the height of the second cylinder 422 is increased, thereby raising the connection height between the piston rod of the second cylinder 422 and the second connecting seat 423. The clearance space is located between the coupling and the machine base 1, which helps to avoid the first connecting seat 412, the first slide 414 and the protective cover 415. The second cylinder 422 and the first connecting seat 412 located in the clearance space are set perpendicular to each other.

[0051] Reference Figure 1 and Figure 6 The waste collection mechanism 5 includes a waste collection box 51 and an inclined guide plate 52. The waste collection box 51 has an upward-facing opening slot. The guide plate 52 is used to guide the cut material head into the waste collection box 51. Four guide plates 52 are arranged in a rectangular array. The upper end of any guide plate 52 is fixed to the inner wall of the machine base 1 by bolts. The lower end of the guide plate 52 extends obliquely above the opening slot of the waste collection box 51. That is, the opening slot of the waste collection box 51 and the lower end of the guide plate 52 are connected to form a continuous waste channel.

[0052] Reference Figure 1 and Figure 6 The four guide plates 52 can smoothly guide the material head falling from the discharge port into the waste collection box 51, realizing the automatic collection and centralized processing of the material head, reducing the steps of manual cleaning of the material head, reducing the labor intensity of the staff, and maintaining the cleanliness of the working environment.

[0053] Reference Figure 1 and Figure 6 The machine base 1 is equipped with a roller assembly 11, and two roller assemblies are symmetrically arranged. The waste collection box 51 is placed on the roller assembly 11. The side wall of the machine base 1 is provided with a push-pull opening 12 for pushing and pulling the waste collection box 51 to avoid it. The operator pushes and pulls the waste collection box 51 through the two roller assemblies 11 at the bottom of the waste collection box 51, so that the operator can clean up and collect the fallen material head in time.

[0054] Reference Figure 1 and Figure 6 Inside the base 1, limit plates 13 are symmetrically installed by bolts. The limit plates 13 are located on both sides of the waste collection box 51. The limit plates 13 are used to guide the waste collection box 51 to slide along the limited trajectory of the roller group 11, so as to prevent the waste collection box 51 from shifting its position during the pushing and pulling process, so that the material head falls out of the collection box.

[0055] Reference Figure 1 and Figure 6The bottom of the base 1 is also equipped with multiple omnidirectional casters 14. In this embodiment, six omnidirectional casters 14 are provided. The omnidirectional casters 14 make it easy for workers to push or pull the cutting machine and to adjust the placement of the cutting machine in the workshop according to production needs.

[0056] The implementation principle of this application embodiment is as follows: In actual operation, the worker first places the injection-molded TV frame on the limited position of the placement frame 2 through the limiting post 21, and then operates the control cylinder 321 to drive the pressure rod 322 to drive the pressing plate 31 to press down the frame. After the frame is pressed, the first cylinder 411 and the second cylinder 422 respectively drive the first cutter 413 and the second cutter 424 to cut off the material head on the frame. The cut material head falls from the discharge port and is guided by the guide plate 52 into the waste collection box 51. After the cutting is completed, the worker operates the control cylinder 321 to drive the pressure rod 322 to drive the pressing plate 31 to move upward, so that the worker can take out the frame. When the waste collection box 51 is full, the worker pulls out the waste collection box 51 to process the material head.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
