Please refer to it. Figure 7 As shown, this is one embodiment of the present invention. Figure 5 The diagram shown is a schematic representation of the overall structure of the placement orientation detection and adjustment mechanism; please refer to it. Figure 8 As shown, this is one embodiment of the present invention. Figure 5Part structure schematic view of the placement direction detection adjusting mechanism in a first perspective view is shown; please refer to Figure 9 As shown in the embodiment of the utility model, the placement direction detection adjusting mechanism is shown in Figure 5 Part structure schematic view of the placement direction detection adjusting mechanism in a second perspective view is shown.

[0028] In Figures 5-9 In the embodiment shown, the placement direction detection adjusting mechanism 120 includes a first product positioning block 121, a placement direction detection assembly 122, and a first gripper assembly 123. The first product positioning block 121 is used to place the heat sink 200 delivered by the feeding mechanism 110. The placement direction detection assembly 122 is used to detect whether the placement direction of the heat sink 200 placed on the first product positioning block 121 is correct. After the detection of the placement direction detection assembly 122 is completed, the first gripper assembly 123 is used to grab the heat sink 200 placed on the first product positioning block 121 and place the grabbed heat sink 200 on the grabbing conveying mechanism 130 in the correct direction based on the detection result of the placement direction detection assembly 122.

[0029] In Figures 7-9 In the embodiment shown, the placement direction detection assembly 122 includes a first vertical drive cylinder 1221, a guide needle 1222, a first horizontal drive cylinder 1223, and a detection needle 1224. The first vertical drive cylinder 1221 is connected with the guide needle 1222, and the first vertical drive cylinder 1221 drives the guide needle 1222 to press or move away from the heat sink 200 placed on the first product positioning block 121 along a first direction (for example, along the up-down direction). The first horizontal drive cylinder 1223 is connected with the detection needle 1224, and the first horizontal drive cylinder 1223 drives the detection needle 1224 to approach or move away from the heat sink 200 placed on the first product positioning block 121 along a second direction (for example, along the front-back direction). The first direction is perpendicular to the direction of the heat sink 200, and the second direction is parallel to the direction of the heat sink 200.

[0030] When the feeding mechanism 110 delivers the heat sink 200 to the first product positioning block 121, the first vertical driving cylinder 1221 drives the guiding needle 1222 to press the heat sink 200 on the first product positioning block 121 in the first direction; then, the first horizontal driving cylinder 1223 drives the detecting needle 1224 to approach the heat sink 200 on the first product positioning block 121 in the second direction, if the detecting needle 1224 is blocked by the convex point on the heat sink 200, it indicates that the placing direction of the heat sink 200 is correct, if the detecting needle 1224 is not blocked by the convex point on the heat sink 200, it indicates that the placing direction of the heat sink 200 is incorrect; when the first vertical driving cylinder 1221 drives the guiding needle 1222 to reset (i.e. back to the initial position), and the first horizontal driving cylinder 1223 drives the detecting needle 1224 to reset (i.e. back to the initial position), if the placing direction detection assembly 122 detects that the placing direction of the heat sink 200 is correct, the first gripper assembly 123 grabs the heat sink 200 placed on the first product positioning block 121 and places it on the grabbing conveying mechanism 130; if the placing direction detection assembly 122 detects that the placing direction of the heat sink 200 is incorrect, the first gripper assembly 123 grabs the heat sink 200 placed on the first product positioning block 121 and rotates it by 180 degrees, and then places it on the grabbing conveying mechanism 130.

[0031] In Figure 8 and Figure 9In the shown embodiment, the first product positioning block 121 is provided with a first placement position 1211 and a second placement position 1212. After the feeding mechanism 110 delivers the heat sink 200 to the first placement position 1211 of the first product positioning block 121, the first vertical driving cylinder 1221 drives the guiding needle 1222 to press the heat sink 200 on the first placement position 1211 in the first direction. Then, the first horizontal driving cylinder 1223 drives the detecting needle 1224 to approach the heat sink 200 on the first placement position 1211 in the second direction. If the detecting needle 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 detecting needle 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. After the first vertical driving cylinder 1221 drives the guiding needle 1222 to reset (i.e., return to the initial position) and the first horizontal driving cylinder 1223 drives the detecting needle 1224 to reset (i.e., return to the initial position), the heat sink 200 is delivered from the first placement position 1211 to the second placement position 1212 of the first product positioning block 121. If the placement direction detection assembly 122 detects that the placement direction of the heat sink 200 is correct, the first gripper assembly 123 grabs the heat sink 200 placed on the second placement position 1212 of the first product positioning block 121 and places it on the grabbing and conveying mechanism 130. If the placement direction detection assembly 122 detects that the placement direction of the heat sink 200 is incorrect, the first gripper assembly 123 grabs the heat sink 200 placed on the second placement position 1212 of the first product positioning block 121, rotates it by 180 degrees, and then places it on the grabbing and conveying mechanism 130.

[0034] When the placement direction detection assembly 122 completes the detection, the second vertical driving cylinder 1234 drives the first mechanical gripper 1231 to move towards the first product positioning block 121 (e.g., the second placement position 1212 of the first product positioning block 121) in the first direction (e.g., up-down direction); then, the first gripping cylinder 1232 drives the first mechanical gripper 1231 to grip the heat sink 200 placed on the first product positioning block 121 (e.g., the heat sink 200 placed on the second placement position 1212 of the first product positioning block 121); next, the second vertical driving cylinder 1234 drives the first mechanical gripper 1231 to move away from the first product positioning block 121 (e.g., the second placement position 1212 of the first product positioning block 121) in the first direction (e.g., up-down direction); if the placement direction detection assembly 122 detects that the placement direction of the heat sink 200 is correct, the stepping motor 1233 does not work; if the placement direction detection assembly 122 detects that the placement direction of the heat sink 200 is incorrect, the stepping motor 1233 works to drive the first mechanical gripper 1231 to rotate by 180 degrees (i.e., the heat sink 200 rotates by 180 degrees); the second horizontal driving cylinder 1235 drives the first mechanical gripper 1231 to move to the gripping conveying mechanism 130 in the third direction (e.g., left-right direction); the second vertical driving cylinder 1234 drives the first mechanical gripper 1231 to move towards the gripping conveying mechanism 130 in the first direction (e.g., up-down direction); and the first gripping cylinder 1232 drives the first mechanical gripper 1231 to release the heat sink 200 so that the heat sink 200 is placed on the gripping conveying mechanism 130.

The third direction is parallel to the direction of the heat sink, for example, the left-right direction.

[0044] In order to facilitate understanding of the present application, the main working process of the heat sink assembly automatic assembling device provided by the present application is specifically introduced as follows. Figures 5-12

[0045] First, the parts (for example, heat sinks) from the material vibrating conveying channel 114 flow to the first placement position 1211 of the first product positioning block 121 (for example, the first placement position 1211 of the first product positioning block 121 is shown in FIG. 6). Figure 8 and Figure 9 ​As shown, after the proximity switch senses the part, it sends a feedback signal to the PLC (Programmable Logic Controller), which then sends a command to the first vertical drive cylinder (or pressing cylinder) 1221. The first vertical drive cylinder (or pressing 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 pressing cylinder) 1221 illuminates, it sends a feedback signal to the first horizontal drive cylinder (or detection pin cylinder) 1223 through the program, causing it to push the detection pin 1224 forward and onto the part. If the detection pin 1224 can push against the protrusion on the part, the direction is correct. Conversely, if the detection pin 1224 can pass through the part without being blocked by the protrusion, the direction is reversed (or incorrect). After inspection, the detection needle 1224 and guide needle 1222 are reset, and the parts flow to the second placement position (or the gripping position) 1212, where the parts are held in place by the front and rear cylinders 1225 (to prevent the stacking of parts from being transported from the rear).

[0046] After inspection by the detection needle 1224, the magnetic switch of the first horizontal drive cylinder (or detection needle cylinder) 1223 sends a feedback signal to the first gripper assembly 123, and the first mechanical gripper 1231 descends to grip the part. If the part is in the correct orientation, the first mechanical gripper 1231 grips the part without rotating it 180 degrees, and moves it to the second product positioning block 131 via the second horizontal drive cylinder 1235. Figure 10 As shown, when the optical fiber on the second product positioning block 131 senses a part, it sends a feedback signal to the PLC. The PLC then sends instructions to the second gripping cylinder 133 and the third horizontal drive cylinder 134, causing the second gripping cylinder 133 to move forward and use the second mechanical gripper 132 to grip the part. After the part is gripped, the third vertical drive cylinder (or up-down cylinder) 135 lifts the part, retracting the second mechanical gripper 132 and the second gripping cylinder 133. The servo module 137 then moves to the right and transports the part to the pressing mechanism 140.

[0047] On the pressing mechanism 140, the operator manually places the PTC component 300 into the positioning component 141 beforehand and presses the equipment start button 50 (e.g., Figure 13 (As shown) clamping. Then, the heat sink 200, delivered by the servo module 137, is placed onto the PTC assembly 300 via the second mechanical gripper 132. After the second mechanical gripper 132 retracts to its original position, the electric cylinder module 143 presses the push block 142 down to press the heat sink 200 onto the PTC assembly 300 until it reaches the bottom, completing one assembly process. During the pressing process, the guide cylinder 144 pushes in the guide blocks 145 on both sides to guide the PTC assembly 300 and prevent tilting. Figure 13The button module of the heat dissipation fin assembly automatic assembling device in an embodiment of the utility model is shown in the schematic view. Figure 13 The button module shown includes an emergency stop button 30, a pause button 40 and a start button 50.

[0048] Through the above step flow, then conveying press fitting, until the heat dissipation fin 200 is assembled 32 pieces, the equipment alarms, then puts the fixing frame 400, and can be put in place, re-presses the start button 50, and carries out automatic assembly. 67 heat dissipation fins 200 are assembled, the equipment cylinder is automatically loosened, then the product is taken out and put into the material frame. That is, the assembly of a product is completed.

[0049] In summary, the heat dissipation fin assembly automatic assembling device has the following beneficial effects:
