Technical Field

[0001] This utility model relates to the field of automated production and processing technology of electronic components, and specifically to a cutting mechanism. Background Technology

[0002] Heat sinks are crucial heat dissipation devices for heat-generating electronic components in electrical appliances. They are typically made of aluminum alloy, brass, or bronze and are widely used in computer CPUs, television power transistors, horizontal output transistors, and power amplifier transistors in amplifiers. The manufacturing quality of heat sinks directly affects the heat dissipation efficiency and performance of electronic devices.

[0003] During the cutting process, the existing heat sinks are prone to movement, causing cutting deviation and affecting cutting accuracy. Furthermore, after cutting, the heat sinks fall and pile up directly, causing scratches between them, affecting their surface quality and failing to meet processing requirements. Summary of the Invention

[0004] The purpose of this invention is to provide a cutting mechanism to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cutting mechanism, comprising:

[0007] A frame on which cutting components and a positioning plate are installed;

[0008] The positioning plate is provided with positioning components that cooperate with the material and multiple independent cutting spaces arranged in an array. The opposite walls of the cutting spaces are provided with abutments and receiving components that can be moved into the space.

[0009] The material is placed on the positioning plate, and through the cooperation of the cutting component and the abutment, the workpiece on the material is cut off and dropped onto the receiving component, so that the workpiece is positioned and adsorbed before being transferred.

[0010] As a preferred embodiment of the present invention, the cutting assembly includes: a first cylinder disposed on the frame, an upper plate connected to the drive end of the first cylinder, a lower plate connected to the upper plate via a spring seat, and a cutting element disposed between the upper plate and the lower plate.

[0012] As a preferred embodiment of the present invention, the cutting component includes: two cutting ends disposed within the lower plate and forming a punching hole, and the upper plate is provided with a cutting blade extending into and out of the punching hole.

[0013] In a preferred embodiment of this utility model, both the upper plate and the lower plate are sleeved on the guide post located on the positioning plate, and move up and down along the guide post.

[0014] As a preferred embodiment of this utility model, the frame is provided with a support plate, the support plate is provided with a pad for supporting the positioning plate, and the support plate is also provided with a through hole located at a corresponding position below the cutting space.

[0015] As a preferred embodiment of the present invention, the abutment includes: a base disposed between the support plate and the positioning plate, the base being provided with a locking block that engages with the positioning plate, and one end of the locking block being provided with an extension block facing the receiving component and corresponding to the cutting position on the material.

[0016] As a preferred embodiment of this utility model, the receiving component includes: a frame, a second cylinder disposed on the frame, a slide plate connected to the drive end of the second cylinder, a ring sleeve disposed on the slide plate, a suction cup seat assembled in the ring sleeve and corresponding one-to-one with the cutting space; and a linear module that cooperates with and is connected to the frame.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] See Figures 1 to 2As shown, this embodiment of the invention provides a cutting mechanism, including: a frame 100, on which a cutting assembly 200 and a positioning plate 300 cooperating with it are disposed. The positioning plate 300 is provided with a positioning element that cooperates with a material 500 and a plurality of independent cutting spaces 31 arranged in an array. Abutments 600 are disposed on the opposite walls of the cutting spaces 31, and a receiving assembly 400 that moves into the space. The material 500 is placed on the positioning plate 300, and through the cooperation of the cutting assembly 200 and the abutments 600, the workpiece on the material 500 is cut off and falls onto the receiving assembly 400, so that the workpiece is positioned, adsorbed, and then transferred.

[0033] Using the transport equipment from the previous process, the transported material 500 is positioned on the positioning plate 300. This material 500 is the heat sink 52 to be processed. (See reference...) Figure 1 As shown, there are multiple heat sinks 52, spaced apart on a material plate 51. The material plate 51 has positioning holes 54, and the positioning plate 300 has positioning posts 32. Together, they ensure the material body 500 is stably placed for cutting. After the material body 500 is placed, the cutting assembly 200 cuts it, separating the heat sinks 52 from the material plate 51. The heat sinks 52 fall onto the receiving assembly 400, where the distance between the receiving assembly 400 and the material body 500 is 1-2 mm to ensure the heat sinks 52 fall stably and at their designated positions on the receiving assembly 400. Subsequently, the receiving assembly 400 transfers the heat sinks 52 to the next processing position. This ensures the cut product surface is not scratched or damaged, improving the product's surface quality and meeting processing requirements.

[0034] Specifically, see Figure 3 As shown, the cutting assembly 200 includes: a first cylinder 21 disposed on the frame 100, an upper plate 22 connected to the drive end of the first cylinder 21, a lower plate 23 connected to the upper plate 22 via a spring seat 24, and a cutting piece 25 disposed between the upper plate 22 and the lower plate 23. By driving the first cylinder 21, the upper plate 22 moves downward, and the lower plate 23 moves downward synchronously. After the lower plate 23 presses against the material body 500, the driving end of the first cylinder 21 continues to drive the upper plate 22 to move. The upper plate 22, carrying the cutting piece 25, cuts the heat sink 52 on the material plate 51. When the lower plate 23 just contacts the material body 500, the setting of the spring seat 24 avoids hard contact between the lower plate 23 and the material body 500, which would cause wear on the surface of the material body 500. After the cutting is completed, when the first cylinder 21 drives the upper plate 22 and the lower plate 23 to return to their original positions, the rebound force provided by the spring seat 24 makes the lower plate 23 quickly move away from the material body 500, improving efficiency.

[0035] Among them, see Figure 4As shown, the cutting components 25 are arranged in a front-to-back configuration, with at least four groups. Each cutting component 25 includes two cutting ends 251 disposed within the lower plate 23 and forming a punching hole 253, and a cutting blade 252 extending into and out of the punching hole 253 on the upper plate 22. During cutting, the cutting ends 251 first contact and press against the heat sink 52. Driven by the first cylinder 21, the cutting blade 252 moves from the punching hole 253, cutting the connection between the heat sink 52 and the material plate 51, thus cutting off the heat sink 52. (See reference...) Figure 5 As shown, the invisible outlines are the lower plate 23 and the cutting piece 25. Using a set of two cutting pieces 25 reduces contact between the cutting end 251 and the heat sink 52, preventing surface wear or scratches on the heat sink 52. Furthermore, the front and rear cutting ends 251 ensure the material 500 remains horizontally balanced when pressed. Then, the edge of the cutting blade 252 presses down to the connection between the heat sink 52 and the material plate 51, ensuring both ends of the heat sink 52 bear pressure and maintain pressure balance. Simultaneously, this arrangement ensures the heat sink 52 remains horizontally positioned when it falls onto the receiving assembly 400. The number of cutting pieces 25 can be arranged according to the material 500 or design requirements.

[0036] Furthermore, both the upper plate 22 and the lower plate 23 are fitted onto guide posts 11 located on the positioning plate 300 and move up and down along these guide posts 11. The guide posts 11 ensure that the movement of the upper plate 22 and the lower plate 23 is perpendicular to the positioning plate 300, avoiding skewing and friction, and improving cutting accuracy and stability. This is crucial for applications requiring precise cutting. It also prevents vibration and deformation that may occur during the cutting process, further improving cutting accuracy.

[0037] Additionally, see Figure 6 As shown, a support plate 12 is provided on the frame 100. The support plate 12 is provided with pads 121 for supporting the positioning plate 300. The support plate 12 also has through holes 122 located at corresponding positions below the cutting space 31. This ensures that the positioning plate 300 remains stable during cutting, avoids shaking and deformation, and improves cutting accuracy.

[0038] The abutment 600 includes: a base 61 disposed between the support plate 12 and the positioning plate 300, a locking block 62 disposed on the base 61 and engaging with the positioning plate 300, and an extension block 63 disposed at one end of the locking block 62 facing the receiving component 400 and corresponding to the cutting position on the material 500.

[0039] The engaging action of the locking block 62 and the positioning plate 300 ensures the precise positioning of the abutment 600. (See attached image.) Figure 5 and 7As shown, this ensures that the edge of the extension block 63 is precisely aligned with or shorter than the connection point between the heat sink 52 and the material plate 51, so that the heat sink 52 can be smoothly cut off.

[0040] See Figure 8 As shown, the receiving component 400 includes: a frame 41, a second cylinder 42 disposed on the frame 41, a slide plate 43 connected to the drive end of the second cylinder 42, a ring 44 disposed on the slide plate 43, a suction cup seat 45 assembled in the ring 44 and corresponding one-to-one with the cutting space 31; and a linear module 46 that is connected to and cooperates with the frame 41.

[0041] Driven by the linear module 46, the frame 41 moves, simultaneously moving the suction cup base 45 during cutting. When the suction cup base 45 moves below the through hole 122, the second cylinder 42 drives the slide plate 43 to move the suction cup base 45 into the through hole 122 and the cutting space 31. At this time, the top of the suction cup base 45 is very close to the material 500, ensuring that the cut heat sink 52 falls accurately onto the suction cup base 45. Then, the second cylinder 42 drives the suction cup base 45 out of the cutting space 31 and the through hole 122. Next, the linear module 46 moves the adsorbed heat sink 52 to the reference. Figure 1 The location of the invisible outline shown is best prepared for the next process.

[0042] The suction cup base 45 is equipped with a support platform 451, with limit blocks 452 located at the edge of the support platform 451 and a suction hole 453 located in the middle. When the heat sink 52 falls onto the support platform 451, the air pressure inside the suction cup is lower than the external atmospheric pressure, thus pressing the object firmly onto the suction cup. In other words, the heat sink 52 is adsorbed through the suction hole 453. This is existing technology and will not be elaborated further. Furthermore, due to the extremely close distance, the heat sink 52 falls precisely between the limit blocks 452, reducing the need for subsequent position adjustments of the heat sink 52 and improving processing efficiency and transfer stability.

[0043] In addition, grooves 454 that cooperate with the abutment 600 are provided on the two opposite sides of the suction cup base 45. Because the distance between the suction cup base 45 and the heat sink 52 is very close, and the extension block 63 on the abutment 600 is the surface of the protruding block 62, the grooves 454 that cooperate with it are provided on the suction cup base 45 to ensure the distance between the top of the suction cup base 45 and the material 500, thereby improving the stability and accuracy of the heat sink 52 falling after cutting.

[0044] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
