In the variable-frequency air conditioner module, IGBT, rectifier bridge, etc. are all high-power devices with high heat generation. Heat sinks are needed to assist in heat dissipation for the normal operation of the equipment. In the production and processing of heat sinks, the staff mainly puts the heat sink raw materials into the cutting machine to obtain the heat sink unit. Then, according to customer requirements, the heat sink unit is put into the stamping machine, punching machine and tapping machine for further manual processing. However, in the further processing process, the staff needs to repeat the loading, positioning and unloading processes.

The workpiece moves to the bottom of the corresponding hole processing device, and the moving mechanism drives the processing end to move and performs hole processing on the workpiece. After the processing is completed, multiple second clamping members extend out of the avoidance space to clamp the multiple workpieces respectively, and the second material moving assembly drives the multiple second clamping members to continue to move in the conveying direction of the second conveyor, so that the workpiece moves to the next hole processing device.

[0030] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6The heat sink processing machine includes a workbench 110, on which are disposed: a first conveying device 120, which has a first conveying path 121 and a first material moving assembly having a first clamping member, the first material moving assembly can drive the first clamping member to move back and forth along the first conveying path 121; a second conveying device 130, which has a second conveying path 131 and a second material moving assembly having a second clamping member 630, the second conveying path 131 has an avoidance space 640, the second material moving assembly is located below the second conveying path 131, the second material moving assembly can drive the second clamping member 630 to move back and forth along the second conveying path 131, and the second clamping member 630 can enter and exit the avoidance space 640; a conveying switching device 140, the conveying switching device 140 The first conveyor 121 has a pushing end for pushing the workpiece on the conveying end of the first conveyor 121 to the conveying start end of the second conveyor 131; a punching device 150 is arranged beside the first conveyor 121, and the punching device 150 includes an upper and lower driving member 530 and a punching assembly with a punch 370. A blanking channel is provided on the first conveyor 121, and the upper and lower driving members 530 are arranged above the first conveyor 121. The upper and lower driving members 530 can drive the punching assembly to move up and down, and make the punch 370 enter or exit the blanking channel; a cutting device 160 is arranged beside the first conveyor 121, and the cutting device 160 includes a cutting knife 410, which cuts the material The knife 410 can move back and forth along the conveying direction perpendicular to the first conveying path 121; the hole processing device 170 is arranged on the side of the second conveying path 131 and is located above the second conveying device 130. Multiple hole processing devices 170 are arranged at intervals along the conveying direction of the second conveying path 131. The hole processing device 170 includes a moving mechanism and a processing end 540. The moving mechanism is arranged above the second conveying path 131, and the processing end 540 is arranged on the moving mechanism. A plurality of second clamping members 630 are arranged in an array on the second material moving assembly, and the spacing between two adjacent second clamping members 630 is the same as the spacing between two adjacent hole processing devices 170.

[0031] The raw material is placed on the first conveyor 121, and then intermittent loading can be achieved through the first material moving assembly. After the raw material passes the cutting device 160 and is transferred to the punching device 150, the punching device 150 punches and presses the raw material to achieve raw material positioning. Then, the cutting device 160 cuts the raw material into a portion of the workpiece, and transfers the workpiece to the second conveyor 131 through the conveying switching device 140. The second material moving assembly intermittently transfers the workpiece to multiple hole processing devices 170, and the hole processing device 170 processes the workpiece transferred to the corresponding position. The user allows the raw material to directly pass through the stamping, cutting, and hole processing procedures to form the workpiece required by the customer, thereby improving the efficiency of workpiece processing, reducing the production cycle, increasing the production volume, reducing labor costs, and improving production efficiency. In fact, the punching device 150 can be set upstream or downstream of the cutting device 160 along the first conveyor 121. In addition, the casing set under the workbench 110 can be fully enclosed, and the lower part of the casing is made into a beveled chip collection box as a whole to facilitate chip removal.

[0032] In addition, in some embodiments, the first material moving assembly also includes a pushing cylinder 210, which is arranged on the workbench 110. The first clamping member includes a first slider 220 and a first pressing cylinder 230. The first slider 220 is slidably arranged on the workbench 110. The driving end of the pushing cylinder 210 is connected to the first slider 220. The pushing cylinder 210 can drive the first slider 220 to slide back and forth along the first conveying path 121. The first pressing cylinder 230 is arranged on the first slider 220 and is located above the first conveying path 121. The driving end of the first pressing cylinder 230 extends downward and is provided with a pressing plate. The first pressing cylinder 230 can drive the pressing plate to move up and down.

[0033] Specifically, because it is necessary to pause when loading during the subsequent processing of the workpiece, the equipment can perform processes such as cutting and stamping on the radiator raw materials during the pause time. The first pressing cylinder 230 is set on the first slider 220. When feeding is required, the first pressing cylinder 230 drives the pressing plate downward to press the raw material. Then, the pushing cylinder 210 drives the first slider 220 to slide along the conveying direction of the first conveying path 121, so that the first pressing cylinder 230 clamps the raw material and moves in the conveying direction. After the feeding is completed, the first pressing cylinder 230 drives the pressing plate upward to release the clamping of the raw material, and the pushing cylinder 210 drives the first pressing cylinder 230 to move back, and the cycle is repeated to achieve intermittent loading, which is convenient for subsequent processing of the raw materials and has a reliable structure. In practical applications, two first clamping members may be provided, and the two first clamping members may be connected by a connecting rod, so that the pushing cylinder 210 can act on the two first clamping members at the same time, and the first clamping member can clamp the raw material at the same time, which can improve the feeding stability and reduce slippage.

[0034] In order to improve the stamping accuracy, in some embodiments, the upper and lower driving components 530 are booster cylinders 310, and the punching assembly also includes an upper die 320, a spring 330 and a stripper plate 340 arranged from top to bottom. Both sides of the first conveying path 121 protrude upward to form a lower die 350, and the blanking channel is located at the end surface of the lower die 350. The bottom surface of the upper die 320 is provided with a first guide column 360 and a punch 370. The first guide column 360 extends downward and passes through the stripper plate 340. One end of the spring 330 is connected to the bottom surface of the upper die 320, and the other end of the spring 330 is connected to the top surface of the stripper plate 340. The stripper plate 340 can move up and down along the first guide column 360, and the end surface of the stripper plate 340 is provided with a stamping channel. The stamping channel and the blanking channel both correspond to the shape and position of the punch 370. The punch 370 extends into the stamping channel. When the booster cylinder 310 drives the edge punching assembly to move downward, the spring 330 is in a compressed state, the bottom surface of the stripping plate 340 is against the top surface of the lower die 350, and the punch 370 passes through the stamping channel and enters the blanking channel.

[0035] Specifically, the boost cylinder 310 drives the punch assembly to move downward, so that the stripper plate 340 and the lower die 350 are against each other, and the boost cylinder 310 continues to drive the upper die 320 and the spring 330 to press downward, so that the vertical distance between the upper die 320 and the stripper plate 340 is reduced, and the spring 330 is continuously compressed. After the punch 370 passes through the punching channel and acts on the workpiece, the punch 370 enters the blanking channel, so that the stamping waste can be smoothly separated from the workpiece and discharged. After the stamping is completed, the boost cylinder 310 drives the upper die 320 to move upward, and the punch 370 also moves upward with the upper die 320. Because the spring 330 is in a compressed state, the stripper plate 340 is always under downward pressure, so that the stripper plate 340 The punch 370 always abuts against the lower die 350, and the punch 370 withdraws from the blanking channel and the workpiece and enters the stamping channel. The booster cylinder 310 continues to drive the upper die 320 to rise, and the stripper plate 340 separates from the lower die 350. During the whole process, the stripper plate 340 and the punch 370 are prevented from shaking, thereby improving the structural rigidity and stamping accuracy. In fact, the booster cylinder 310 may start to move up only after the cutting device 160 cuts the raw material, thereby improving the positioning effect of the raw material during cutting and improving the cutting accuracy.

[0036] In addition, in some embodiments, the cutting device 160 also includes a rotating motor 420 and a linear slide 430. The linear slide 430 is slidably set on the workbench 110 and is located below the first conveying path 121. The rotating motor 420 is set on the linear slide 430. A cutting gap 260 is provided on the first conveying path 121. The cutting knife 410 extends out of the cutting gap 260. A plurality of blades are provided around the cutting knife 410. The linear slide 430 can drive the rotating motor 420 to move back and forth in a direction perpendicular to the first conveying path 121. The rotating motor 420 drives the cutting knife 410 to rotate, and the rotation axis of the cutting knife 410 coincides with its center line. The workpiece material has a certain thickness. By rotating the cutting knife 410 and driving the cutting knife 410 to cut in a direction perpendicular to the first conveying path 121, the cutting strength and effect can be improved. In addition, the rotating axis of the cutting knife 410 is located below the first conveying path 121, which can reduce the height of the equipment, make full use of the installation space, compactly install, and improve the aesthetics. Moreover, further, in some embodiments, the cutting device 160 also includes a positioning block 240 and a second pressing cylinder 250. The positioning block 240 and the second pressing cylinder 250 are both arranged on the workbench 110. The positioning block 240 and the second pressing cylinder 250 are respectively arranged on both sides of the first conveying path 121. The positioning block 240 and the second pressing cylinder 250 are both located in front of the cutting knife 410. A top plate is provided on the driving end of the second pressing cylinder 250. The second pressing cylinder 250 can drive the top plate to move in the direction of the first conveying path 121. Before cutting the raw material, the second pressing cylinder 250 drives the top plate to move in the direction of the first conveying path 121, so that the top plate presses the raw material toward the positioning block 240, realizes the horizontal positioning of the raw material, prevents the raw material from shaking when the cutting knife 410 cuts the raw material, improves the cutting accuracy, reduces the deformation of the raw material, and prevents the raw material from bending and breaking in the horizontal direction. In addition, the cutting device 160 can also include a chip collecting cover, which is arranged on the linear slide 430, the chip collecting cover is covered on the lower part of the cutting knife 410, and a chip outlet is provided at the bottom along the rotation direction of the cutting knife 410, which is obliquely downward to facilitate chip removal. The cutting device 160 can also be provided with a reinforcing baffle, which is arranged on the workbench 110 and connects the two sides of the cutting gap 260, so as to improve the strength of the workbench 110 and prevent chips from splashing.

[0037] In order to improve production efficiency and reduce space occupancy, in some embodiments, the second material moving assembly also includes a feeding cylinder 610 and a second slider 620. The feeding cylinder 610 is arranged on the workbench 110, and the second slider 620 is slidably arranged on the bottom surface of the workbench 110. The driving end of the feeding cylinder 610 is connected to the second slider 620. The feeding cylinder 610 can drive the second slider 620 to slide back and forth along the second conveying path 131. A plurality of second clamping members 630 are arranged at intervals on the second slider 620, and the number of the second clamping members 630 is one less than the number of the hole processing device 170. After the previous hole processing device 170 completes processing of the corresponding workpiece, the second clamping member 630 clamps the workpiece on the second conveying path 131, and the feeding cylinder 610 drives the second slider 620 to slide along the conveying direction of the second conveying path 131, so that the workpieces on multiple second clamping members 630 can be simultaneously conveyed in the direction of the next hole processing device 170 to realize the next step of processing of the workpiece. Multiple second clamping members 630 make it possible to act on multiple workpieces at the same time, thereby improving production efficiency. In addition, because the workpiece at the last hole processing device 170 station can be automatically squeezed out along the direction of the second conveying path 131 during the transportation of its next workpiece, the number of second clamping members 630 is one less than the number of hole processing devices 170, thereby maximizing the transportation efficiency while reducing space occupancy and reducing production costs.

[0038] Furthermore, in some embodiments, the second clamping member 630 includes a clamping cylinder 710, a rack 810 and a clamping arm 720. The clamping cylinder 710 is arranged on the second slider 620, and the rack 810 is vertically arranged on the driving end of the clamping cylinder 710 extending upward. Teeth are arranged on the opposite side surfaces of the rack 810, and the orientation of the teeth is consistent with the setting direction of the second conveying path 131. A connecting block 820 is arranged at one end of the clamping arm 720. The connecting block 820 is in the shape of a cylindrical gear. The connecting block 820 is rotatably connected to the second slider 620, and the rotation axis of the connecting block 820 coincides with the center line of the connecting block 820. The two clamping arms 720 are respectively meshed and arranged on both sides of the rack 810 with teeth. When the clamping cylinder 710 drives the rack 810 to move downward, the ends of the two clamping arms 720 away from the connecting block 820 approach each other and can enter the avoidance space 640. The workpiece is transported on the second conveying path 131, and the avoidance space 640 is set on the second conveying path 131. When the clamping cylinder 710 drives the rack 810 to move downward, the top ends of the two clamping arms 720 approach each other and enter the avoidance space 640 to clamp the workpiece. When the clamping cylinder 710 drives the rack 810 to move upward, the top ends of the two clamping arms 720 move away from each other and exit the avoidance space 640 to release the clamping of the workpiece, so that when the clamping arms 720 are transferred back along the second conveying path 131, interference between the clamping arms 720 and the workpiece is prevented, and the structure is reliable. It should be noted that, because the workpiece is supported on the second conveying path 131, during the clamping process, the workpiece has a clamp arm 720 on the surface opposite to the transportation direction, and the clamp arm 720 can directly fiddle with the workpiece, and the workpiece has a good moving effect. The clamp arm 720 extends upward to avoid the space 640. Compared with the structure of clamping the workpiece from above, the workpiece can be prevented from falling due to the shaking of the clamp arm 720, and there is no need to use an up and down driving structure to move the clamp arm 720, which reduces the design cost. Moreover, the clamp arm 720 on the surface of the workpiece facing the same direction as the transportation direction can prevent the workpiece from being offset due to inertia during the movement of the workpiece, thereby improving the displacement stability. In fact, during the hole processing, the clamping device can always be in a clamped state, which can prevent the workpiece from slipping and improve the processing stability. In addition, a limit table can be provided on the upper side of the clamp arm 720 close to the workpiece, so that the bottom surface of the limit table can fit with the surface of the workpiece, prevent the workpiece from shaking, and improve the stability of the workpiece during movement and processing.

[0039] In addition, in order to improve the positioning effect of the workpiece during the hole processing process, in some embodiments, both sides of the second conveying path 131 are surrounded by guide platforms, and the side walls of the two guide platforms close to each other are provided with supporting blocks along the direction of the second conveying path 131. The second conveying device 130 also includes a positioning component, and the positioning component includes a positioning cylinder 730, a second guide column 750 and a fixed plate 760. The positioning cylinder 730 is arranged on the workbench 110, and a supporting plate 740 is provided on the driving end of the positioning cylinder 730. The positioning cylinder 730 can drive the supporting plate 740 to move up and down. The second guide column 750 is arranged on the top surface of the supporting plate 740. A positioning channel runs through the guide table and the workbench 110. The second guide column 750 extends upward and passes through the positioning channel. The fixed plate 760 is arranged at the top of the second guide column 750, and the bottom surface of the fixed plate 760 is provided with a positioning pin 770 extending downward. The top surface of the supporting block is provided with a positioning hole matching the position and shape of the positioning pin 770. Multiple positioning components and multiple hole processing devices 170 The number and position of the heat sink are in one-to-one correspondence. In fact, the top plate of the heat sink is placed on the top surface of the two supporting blocks, and the fins of the heat sink are arranged on the bottom surface of the top plate. The bottom end of the fin extends downward and abuts against the second conveying path 131. After the second clamping member 630 clamps the workpiece and moves to the next station, the positioning cylinder 730 drives the supporting plate 740 to move downward, and the second guide column 750 and the fixed plate 760 thereon also move downward with the supporting plate 740. The positioning pin 770 passes through the hole position of the workpiece and enters the positioning hole. After the positioning is completed, the hole position of the workpiece can be processed, which improves the support and positioning ability of the workpiece, prevents the deformation of the workpiece, improves the processing accuracy, and has a simple and reliable structure. In addition, it improves the space utilization rate, reduces the space occupied by the second clamping member 630 and the hole processing device 170, and improves the aesthetics. It should be noted that two second guide columns 750 can be provided on the supporting plate 740, and the distances between the two second guide columns 750 and the positioning cylinder 730 are the same, which improves the stability of the positioning process.

[0040] In addition, in some embodiments, the conveying switching device 140 also includes a conveying path, and the conveying path, the first conveying path 121, and the second conveying path 131 are all horizontally arranged on the workbench 110. The beginning and end ends of the conveying path are both connected to the first conveying path 121 and the second conveying path 131. The conveying path is perpendicular to the first conveying path 121 and the second conveying path 131 respectively. The pushing end includes a first pushing cylinder and a second pushing cylinder both horizontally arranged on the workbench 110. The first pushing cylinder is located beside the conveying end of the first conveying path 121, and the driving end of the first pushing cylinder extends in the conveying direction of the conveying path. The second pushing cylinder is located beside the conveying end of the conveying path, and the driving end of the second pushing cylinder extends in the conveying direction of the second conveying path 131. Specifically, the first pushing cylinder pushes the workpieces accumulated at the end of the first conveying path 121 onto the conveying path, and the second pushing cylinder pushes the workpieces squeezed to the end of the conveying path onto the second conveying path 131. The equipment adapted to different setting spaces provides a pushing force for transporting the workpieces to the second conveying path 131, which is convenient for workers to monitor and reduces material stacking. In fact, an interception member may be provided at the beginning of the second conveyor 131. The interception member includes an interception cylinder and an interception rod arranged on the workbench 110. The interception rod is horizontally arranged on the driving end of the interception cylinder. The extension direction of the interception rod is perpendicular to the conveying direction of the second conveyor 131. The interception cylinder can drive the interception rod to move up and down. When the interception cylinder drives the interception rod to move downward, the interception rod can intercept the workpiece at the beginning of the second conveyor 131, and cooperate with the conveying end of the conveying switching device 140 to make the position of the workpiece more accurate, which is convenient for the clamping of the second clamping member 630. In fact, the first conveyor 121 and the second conveyor 131 can be parallel to each other, so that the feed port and the discharge port are located on the same side, which is convenient for loading and unloading and shortening the length of the entire heat sink processing machine. In addition, it can be changed to a direct-down material transfer, with the feed port and the discharge port located on different sides, so that the material transfer path of the conveyor is greatly shortened, the transportation efficiency is improved, and it is convenient for workers to monitor and clean aluminum chips during the production process of the workpiece.

[0041] In addition, the moving mechanism includes a front-to-back driving member 510, a left-to-right driving member 520, and an up-to-down driving member 530. With the conveying direction of the second conveying path as the front, the front-to-back driving member 510 is arranged on the workbench 110, a first mounting block movable in the front-to-back direction is arranged on the front-to-back driving member 510, the left-to-right driving member 520 is arranged on the first mounting block, a second mounting block movable in the left-to-right direction is arranged on the left-to-right driving member 520, and the up-to-down driving member 530 is arranged on the second mounting block, and a processing end 540 is arranged at the lower end of the up-to-down driving member 530, and the up-to-down driving member 530 can drive the processing end 540 to move up and down. The processing end 540 can be a tool for drilling, chamfering or tapping. The processing end 540 can be moved in three positions in space through the front-to-back driving member 510, the left-to-right driving member 520, and the up-to-down driving member 530, so that the processing end 540 can be processed on the surface of the workpiece, thereby improving the functionality and automation effect of use and improving production efficiency. In fact, because the second conveying device 130 is arranged below the workpiece, the height of the moving mechanism can be lowered as a whole, reducing the shaking of the processing end 540 and improving the processing accuracy. The up and down driving member 530, the left and right driving member 520 and the up and down driving member 530 can be a screw slide or a cylinder.
