The first direction is a direction perpendicular to the heat sink 200, and the second direction is a direction parallel to the heat sink 200.

[0030] After the feeding mechanism 110 transfers the heat sink 200 to the first product positioning block 121, the first vertical driving cylinder 1221 drives the guide pin 1222 to press the heat sink 200 located on the first product positioning block 121 along the first direction; then, the first horizontal driving cylinder 1223 drives the detection pin 1224 to approach the heat sink 200 located on the first product positioning block 121 along the second direction. If the detection pin 1224 is blocked by the convex point on the heat sink 200, it indicates that the placement direction of the heat sink 200 is correct. If the detection pin 1224 is not blocked by the convex point on the heat sink 200, it indicates that the placement direction of the heat sink 200 is incorrect. When the first vertical driving cylinder 1221 drives After the guide pin 1222 is reset (i.e., returns to its initial position), and the first horizontal drive cylinder 1223 drives the detection pin 1224 to reset (i.e., returns to its initial position), if the placement direction detection component 122 detects that the placement direction of the heat sink 200 is correct, the first gripper component 123 grabs the heat sink 200 placed on the first product positioning block 121 and places it on the gripping and conveying mechanism 130; if the placement direction detection component 122 detects that the placement direction of the heat sink 200 is incorrect, the first gripper component 123 grabs the heat sink 200 placed on the first product positioning block 121, rotates it 180 degrees, and then places it on the gripping and conveying mechanism 130.

If the detection pin 1224 is blocked by the convex point on the heat sink 200, it indicates that the placement direction of the heat sink 200 is correct. If the detection pin 1224 is not blocked by the convex point on the heat sink 200, it indicates that the placement direction of the heat sink 200 is incorrect. When the first vertical driving cylinder 1221 drives the guide pin 1 After 222 is reset (i.e., returns to the initial position), and the first horizontal driving cylinder 1223 drives the detection needle 1224 to reset (i.e., returns to the initial position), the heat sink 200 is transported from the first placement position 1211 of the first product positioning block 121 to the second placement position 1212.

[0044] In order to facilitate the understanding of the present invention, the following Figure 5-Figure 12 The main working process of the automatic assembly device for heat sink components provided by the present invention is specifically introduced.

[0045] First, the parts (for example, heat sinks) coming out of the vibration material conveying channel 114 flow to the first placement position 1211 of the first product positioning block 121 (for example, Figure 8 and Fig. 9As shown), after the proximity switch senses the part, it feeds back a signal to the PLC (Programmable Logic Controller) program, and then sends a command to the first vertical drive cylinder (or downward pressure cylinder) 1221, and the first vertical drive cylinder (or downward pressure cylinder) 1221 presses the guide pin 1222 to the upper limit of the part. After the magnetic switch light of the first vertical drive cylinder (or downward pressure cylinder) 1221 is on, it feeds back a signal to the first horizontal drive cylinder (or detection needle cylinder) 1223 through the program, causing it to push the detection needle 1224 forward and onto the part. If the detection needle 1224 can push against the convex point of the part, the direction is the correct direction. On the contrary, if the detection needle 1224 can pass through the part and is not blocked by the convex point, the direction is the opposite direction (or incorrect direction). After inspection, the detection needle 1224 and the guide needle 1222 are reset, and the parts flow to the second placement position (or the grasped position) 1212, and the front and rear cylinders 1225 support the parts (the purpose is to avoid stacking of the parts conveyed from behind).

[0046] After the inspection by the detection needle 1224, the magnetic switch of the first horizontal driving cylinder (or the detection needle cylinder) 1223 feeds back a signal to the first gripper assembly 123, and the first mechanical gripper 1231 grabs the part. If the part is in the correct direction, the first mechanical gripper 1231 grabs the part without rotating 180 degrees, and moves it to the second product positioning block 131 through the second horizontal driving cylinder 1235. Fig.10 As shown, when the optical fiber on the second product positioning block 131 senses the part, a feedback signal is sent to the PLC, and then the PLC sends instructions to the second grabbing cylinder 133 and the third horizontal drive cylinder 134, so that the second grabbing cylinder 133 moves forward and the second mechanical gripper 132 grabs the part. After the part is grabbed, it is raised by the third vertical drive cylinder (or upper and lower cylinders) 135, and the second mechanical gripper 132 and the second grabbing cylinder 133 are retracted, and the servo module 137 moves rightward to transport it to the press-fitting mechanism 140.

[0047] On the press-fit mechanism 140, the operator manually places the PTC component 300 on the positioning component 141 in advance, presses the device start button 50 (such as Fig.13 Then the heat sink 200 delivered by the servo module 137 is placed on the PTC component 300 through the second mechanical gripper 132. When the second mechanical gripper 132 returns to its original position, the electric cylinder module 143 presses the heat sink 200 onto the PTC component 300 through the pressing process of the push block 142 until the bottom, completing an assembly process. During the pressing process, the guide cylinder 144 pushes in the guide blocks 145 on both sides to align the PTC component 300 to prevent deflection. Among them, Fig.13FIG. 1 is a schematic diagram of a button module of an automatic assembly device for a heat sink assembly in one embodiment of the present invention. Fig.13 The button module shown includes an emergency stop button 30 , a pause button 40 and a start button 50 .
