[0048] See also Figure 1 The electronic component detection device 1 provided in the embodiment of the present application is now described. The electronic component detection device 1 provided in the embodiment of the present application includes a feeding conveying line 11, a detection device 12 and a screening mechanism 13.

[0049] Reference Figure 1 and Figure 4The loading conveyor line 11 is used to transport the tray 2 carrying the electronic components 3 to be tested, and a detection station 111 and an unloading station 112 are sequentially provided along the conveying direction of the loading conveyor line 11. The loading conveyor line 11 is responsible for transporting the tray 2 carrying the electronic components 3 to be tested from the starting position to the detection station 111 and the unloading station 112, providing a continuous material supply for the entire testing process. Among them, a positioning groove in the shape of the electronic component 3 is provided on the tray 2 corresponding to the electronic component 3, and the electronic component 3 is positioned after being placed on the tray 2. Specifically, the electronic component 3 can be a capacitor, such as a thin film capacitor.

[0050] The detection device 12 is located at the detection station 111 and can contact the contacts 31 of the electronic component 3 to test the electronic component 3. After the electronic component 3 is conveyed to the detection station 111 by the loading conveyor line 11, the detection device can approach the electronic component 3 and then contact the contacts 31 of the electronic component 3 to test the electronic component 3. It can be understood that the detection device 12 may include a conductive component that contacts the contacts 31, a driving component that drives the conductive component to contact the contacts 31, and a detection component for performing a test.

[0051] The screening mechanism 13 includes a three-dimensionally movable picking head, a good product area 132 and a defective product area 133. The picking head is arranged at the unloading station 112. The picking head is used to transport the electronic components 3 after inspection to the good product area 132 or the defective product area 133 according to the inspection results of the inspection device 12.

[0052] The picking head can be a suction cup group and a mechanical claw. The picking head can be installed on a robotic arm or moved by a three-axis moving mechanism. After the inspection is completed, the tray 2 is continued to be transported to the unloading station 112. At this time, the picking head of the screening mechanism 13 begins to play a role. The picking head can move in three dimensions and can accurately locate the electronic component 3 after inspection. According to the inspection results, if the electronic component 3 is a good product, the picking head will move it to the good product area 132; if it is a defective product, it will be moved to the defective product area 133, realizing automatic sorting of the electronic component 3 and improving production efficiency and product quality.

[0053] Based on the above structure, in the electronic component testing device 1 of the embodiment of the present application, the entire testing process is completed automatically by the device without manual intervention, which greatly improves production efficiency and helps reduce labor costs.

[0054] Reference Figure 1 The loading conveyor line 11 includes a first frame 113, two roller assemblies, and a drive assembly. The two roller assemblies are located on either side of the first frame 113. The roller assemblies include multiple rollers arranged along the conveying direction. The two ends of the pallet are respectively mounted on the rollers on both sides. The drive assembly is used to drive the rollers to rotate to convey the pallet 2.

[0055] The driving assembly drives the multiple rollers of the two roller groups to rotate together. The two ends of the tray 2 are respectively placed on the left and right rollers. The electronic components 3 to be tested are located on the tray 2. As the rollers rotate, the tray 2 is transported forward.

[0056] Reference Figure 1 and Figure 2 The screening mechanism 13 further includes a second frame 131 and a three-dimensional motion mechanism 134. The second frame 131 is located at the unloading station 112. The three-dimensional motion mechanism 134 is located on the second frame 131 and is used to drive the pickup head to move three-dimensionally. The three-dimensional motion mechanism 134 can be a three-axis motion mechanism, including an X-axis translation mechanism, a Y-axis translation mechanism, and a Z-axis translation mechanism, and the pickup head is located on the Z-axis translation mechanism.

[0057] Reference Figure 1 and Figure 3 The detection device 12 includes a detection contact member 121 and a first driver 122. The detection contact member 121 can move in the height direction to approach or abut the contact point 31, or move away from the contact point 31. The first driver 122 is used to drive the detection contact member 121 to move in the height direction. When the detection contact member 121 moves in the height direction, it can gradually approach and eventually abut the contact point 31, thereby achieving contact with the contact point 31 for detection; or the detection contact member 121 can also move in the opposite direction, that is, away from the contact point 31, so as to maintain a certain distance from the contact point 31 when detection is not required. Specifically, the detection contact member 121 is a detection probe or a detection clamp.

[0058] The first driver 122 drives the entire detection device 12, driving the detection contact member 121 to move in the height direction. The first driver 122 can drive the detection contact member 121 in a variety of ways, such as motor drive, hydraulic drive, or pneumatic drive. The driving process can be precisely controlled to ensure that the detection contact member 121 accurately moves to the desired position, reliably contacts the contact 31, or maintains an appropriate distance, thereby ensuring the normal operation of the detection device 12 and the accuracy of the detection results.

[0059] Reference Figure 1 and Figure 3The detection device 12 further includes a second driver 123 for driving the detection contact member 121 to move horizontally, either toward or away from the contact point 31. The second driver 123 is configured to drive the detection contact member 121 to move horizontally. When the detection contact member 121 moves horizontally, it can approach and abut the contact point 31 in preparation for a detection operation, or it can move away from the contact point 31 to maintain a safe distance or adjust its position in certain circumstances.

[0060] The second driver 123 can achieve precise horizontal driving of the detection contact member 121 through various mechanical structures and power sources. For example, a cylinder, a servo motor, a stepper motor, a screw-nut mechanism, a rack-and-pinion mechanism, etc. can be used to convert rotational motion into horizontal linear motion to drive the detection contact member 121.

[0061] Reference Figure 1 and Figure 4 The electronic component testing equipment 1 further includes an empty pallet conveying line 14 , a pallet lowering mechanism 15 and a pallet lifting mechanism 16 .

[0062] The empty pallet conveyor line 14 is located below the loading conveyor line 11, and the conveying direction of the empty pallet conveyor line 14 is opposite to that of the loading conveyor line 11. The empty pallet conveyor line 14 is located below the loading conveyor line 11, which can fully utilize the space and make the equipment structure more compact. The conveying direction is opposite to that of the loading conveyor line 11. This reverse conveying design can realize the recycling of empty pallets 2 and improve the working efficiency of the equipment. The empty pallet conveyor line 14 is specifically used to convey empty pallets 2. The empty pallets 2 left after the inspection are transported from the unloading station 112 to the pallet lifting mechanism 16 to provide empty pallets 2 for the next round of inspection.

[0063] Reference Figure 1 and Figure 4 The pallet lowering mechanism 15 is located at the unloading station 112, connecting the conveying end of the loading conveyor line 11 and the conveying front end of the empty pallet conveyor line 14. The pallet lowering mechanism 15 is used to transfer the pallet 2 from the loading conveyor line 11 to the empty pallet conveyor line 14. The pallet lowering mechanism 15 connects the conveying end of the loading conveyor line 11 and the conveying front end of the empty pallet conveyor line 14, so that the pallet 2 that has completed the inspection can be smoothly transferred from the loading conveyor line 11 to the pallet lowering mechanism 15, and then enter the empty pallet conveyor line 14.

[0064] Reference Figure 1 and Figure 4The pallet lifting mechanism 16 is located at the end of the loading conveyor line 11 away from the pallet lowering mechanism 15. The pallet lifting mechanism 16 connects the conveying end of the empty pallet conveyor line 14 and the conveying front end of the loading conveyor line 11. The pallet lifting mechanism 16 is used to transfer the pallet 2 from the empty pallet conveyor line 14 to the loading conveyor line 11. The pallet lifting mechanism 16 connects the conveying end of the empty pallet conveyor line 14 and the conveying front end of the loading conveyor line 11, allowing the empty pallet 2 to be smoothly transferred from the empty pallet conveyor line 14 to the loading conveyor line 11, ready for a new round of inspection.

[0065] That is, through the mutual cooperation of the loading conveyor line 11, the empty pallet conveyor line 14, the pallet descending mechanism 15, and the pallet lifting mechanism 16, the continuous recycling of the pallets 2 can be achieved. That is, the empty pallet 2 is placed on the loading conveyor line 11, and the staff manually places the electronic components 3 to be tested on the pallet 2. The pallet 2 carrying the electronic components 3 reaches the inspection station 111, and after being inspected by the inspection device 12, it continues to be transported forward to the pallet descending mechanism 15, that is, the unloading station 112. The screening mechanism 13 removes the inspected electronic components 3, and the pallet 2 now becomes an empty pallet 2. The pallet descending mechanism 15 transfers the empty pallet 2 to the empty pallet conveyor line 14, and from the empty pallet conveyor line 14 to the pallet lifting mechanism 16, and then the pallet lifting mechanism 16 transfers the empty pallet 2 to the loading conveyor line 11.

[0066] Specifically, the pallet lowering mechanism 15 includes a liftable first supporting plate 151 and a first feeding assembly provided on the first supporting plate 151 . The feeding direction of the first feeding assembly is the same as the conveying direction of the empty pallet conveying line 14 .

[0067] The first support plate 151 can be raised and lowered vertically to match the height of the loading conveyor line 11 and the empty pallet conveyor line 14. To receive an empty pallet 2 from the loading conveyor line 11, the first support plate 151 rises to a position flush with the loading conveyor line 11. To transfer an empty pallet 2 to the empty pallet conveyor line 14, the first support plate 151 descends to a position flush with the empty pallet conveyor line 14. The first feed assembly smoothly pushes the empty pallet 2 from the first support plate 151 onto the empty pallet conveyor line 14.

[0068] The first feed assembly includes a plurality of first rollers and a first drive assembly that drives the first rollers. The plurality of first rollers are rotatably disposed on either side of the first support plate 151 and are divided into two groups. The first drive assembly is used to drive the first rollers. Similar to the loading conveyor line, the ends of the pallet are mounted on rollers on both sides. When the pallet needs to be delivered to the empty pallet conveyor line, the first drive assembly drives the first rollers to deliver the pallet. The first drive assembly may include a motor, a synchronous belt, and a synchronous pulley. The motor drives the plurality of first rollers to rotate via the synchronous belt.

[0069] When the loading conveyor line 11 delivers the inspected pallet 2 and electronic components 3 to the unloading station 112, the picking head of the screening mechanism 13 removes both good and bad products, leaving the empty pallet 2 on the first support plate 151 of the pallet lowering mechanism 15. The first support plate 151 then descends to a position flush with the empty pallet conveyor line 14, and the first feed assembly is activated, feeding the empty pallet 2 onto the empty pallet conveyor line 14.

[0070] The tray lifting mechanism 16 includes a liftable second supporting plate and a second feeding assembly provided on the second supporting plate. The feeding direction of the second feeding assembly is the same as the feeding direction of the loading conveyor line 11 .

[0071] The second support plate 161 is similar to the first support plate 151 and can be raised and lowered in the vertical direction to match the height of the empty pallet conveyor line 14 and the loading conveyor line 11. When it is necessary to receive the empty pallet 2 from the empty pallet conveyor line 14, the second support plate 161 descends to a position flush with the empty pallet conveyor line 14; when the empty pallet 2 is to be transferred to the loading conveyor line 11, the second support plate 161 rises to a position flush with the loading conveyor line 11. The second feeding assembly is then activated to deliver the empty pallet 2 to the loading conveyor line 11. The staff only needs to place the electronic components 3 to be tested on the empty pallet 2 at the entrance of the loading conveyor line 11 to continue testing.

[0072] The second feed assembly includes multiple second rollers and a second drive assembly that drives the second rollers. The multiple second rollers are rotatably mounted on either side of the second support plate 161 and are divided into two groups. The second drive assembly is used to drive the second rollers. Similar to the loading conveyor line, the ends of the pallet are mounted on rollers on both sides. When the pallet needs to be delivered to the empty pallet conveyor line, the second drive assembly drives the second rollers to deliver the pallet. The second drive assembly includes a motor, a synchronous belt, and a synchronous pulley. The motor drives the multiple second rollers via the synchronous belt.

[0073] The specific structure of the empty pallet conveyor line 14 is similar to that of the loading conveyor line 11, with the only difference being that the conveying directions are opposite, which will not be described in detail here.

[0074] Reference Figure 1 and Figure 4 The electronic component inspection device 1 further includes a good-quality conveyor line 17 located in the good-quality area 132 for receiving and conveying the electronic components 3 conveyed by the pickup head. The good-quality conveyor line 17 in the electronic component inspection device 1 is located in the good-quality area 132 and is used to receive and convey good-quality electronic components 3 conveyed by the pickup head. The good-quality conveyor line 17 can be a conveyor belt structure driven by a motor, which can quickly convey good-quality electronic components 3 to subsequent processing or packaging, thereby improving production efficiency.

[0075] Reference Figure 1 and Figure 4 The electronic component inspection device 1 further includes a defective product conveyor line 18 located in the defective product area 133 for receiving and conveying the electronic components 3 carried by the pickup head. The electronic component inspection device 1 is provided with a defective product conveyor line 18 located in the defective product area 133. Its function is to receive defective electronic components 3 carried by the pickup head. It is a conveyor belt structure that can transport defective products to a specific location for subsequent processing.

[0076] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
