[0036] An electrical inspection loading workstation includes a loading device, a transfer unit 5 and a frame 6; the loading device and the transfer unit are arranged on the frame 6. In this embodiment, there are multiple loading devices and they are arranged in parallel;

[0037] like Figure 1 As shown, the feeding device includes a first feeding unit 1, a transfer unit 2, an identification unit and a second feeding unit 3;

[0038] The first loading unit 1 is used to obtain the condoms and transfer them to the transfer unit; specifically, the first loading unit 1 includes a first suction member 11, a first suction drive 12 and a pushing assembly 13, the first suction member 11 includes a first hollow rod, a slide rail 601 is provided at a position corresponding to the first hollow rod on the frame 6, and the first hollow rod is slidably connected to the slide rail 601 up and down, such as Figures 4 to 6 As shown, the lower port of the first hollow rod forms a first suction nozzle 111, the upper port of the first hollow rod is connected to the vacuum pump, and the first suction drive 12 includes a first motor fixed on the frame 6. The first motor drives the first hollow rod to move up and down through a synchronous belt. When the first hollow rod moves downward into the silo, a negative pressure environment is formed in the first hollow rod. Under the action of the pressure difference, the condom is sucked, and then the first hollow rod moves upward to the upper limit, that is, the first position.

[0039] like Figure 2 and 3 As shown, each first feeding unit 1 is also correspondingly provided with a first guide component 4, which is arranged below the first position, and the first guide component 4 forms a first guide channel with an opening facing downwardly of the transfer unit, and the first guide channel is small at the top and large at the bottom, and is trumpet-shaped, and the size of the narrower part of the first guide channel is designed to accommodate only one condom to pass through, so that when the first hollow rod absorbs the condom and moves upward, the condom passes through the first guide channel. At this time, if the condom is stacked, folded, or even hooked on other condoms, the hooked condom will fall back into the silo under the resistance of the first guide component 4, and at the same time, the stacked and folded condoms are combed and shaped, so that the open end and the end of the condom are naturally drooped, so that the condom staying in the first position has a good arrangement state, which is convenient for subsequent operations.

[0040] The pushing assembly 13 can be displaced under the push drive to make the condom close to the material taking position 22, so as to facilitate the material taking position to stably grab the condom. In this embodiment, in order to avoid the first hollow rod interfering with the transfer unit 2 and reduce the position accuracy requirement of the first hollow rod, the first hollow rod is often set at a distance from the transfer unit / 2.

[0041] like Figure 2 and 3 As shown, the pushing assembly 13 includes a pushing nozzle 131 and a pushing arm 132. The pushing nozzle 131 is connected to an external air source and includes a blowing nozzle arranged toward the transfer unit. The blowing nozzle is directed toward the material taking position 22 of the transfer unit 2 at a corresponding position, and the condom can be blown toward the transfer unit 2; the pushing arm 132 includes a U-shaped pushing portion, wherein the side wall of the pushing portion facing the condom is provided with anti-slip grooves to effectively push the condom, such as Figure 3 As shown, the pushing part is arranged on the piston rod of the pushing cylinder. The piston rod moves forward and backward to push the condoms to the material taking position 22 of the condom box transport unit 2.

[0042] The transfer unit 2 includes a turntable 21, which is arranged on the frame 6 and is rotatably connected to the frame 6. A transfer drive is provided at a corresponding position of the frame 6, and the transfer drive can tend to cause the turntable 21 to rotate. Four material collection positions 22 are circumferentially arranged on the outer edge surface of the turntable 21, and the material collection positions 22 can grab and transfer condoms; in this embodiment, the material collection positions 22 are material collection holes provided on the outer edge surface of the turntable, and the four material collection holes are interconnected and connected to an external vacuum pump. The material collection holes can absorb condoms under the action of pressure difference, and then the turntable 21 rotates to transport the condoms to the second loading unit 3.

[0043] In this embodiment, the outer edge surface of the rotating disk 21 includes a plane 23 arranged near the material taking hole, and the plane 23 smoothly transitions with the adjacent material taking hole 22. Figure 5and 6 As shown, the turntable 21 is roughly in the shape of a square disk, wherein when the material taking position 22 faces the first loading unit 1, the material taking position is at a lower position and faces the first loading unit 1, and when the material taking position 22 absorbs the condom and rotates 180° to transport it to the end of its stroke, the plane 23 on the outer edge surface of the turntable 21 is vertically arranged and laterally fits the condom to support the condom. On the one hand, it is convenient for the identification unit to identify and reduce the influence of noise during the identification process. On the other hand, it is convenient for the second loading unit 3 to absorb the condom and avoids sucking the condom in a completely suspended state and without a fulcrum, which is beneficial to improve the success rate of absorption and improve the stability and continuity of feeding. The design is ingenious.

[0044] In addition, the turntable 21 is designed so that when the feeding hole sucks up the condom, the turntable 21 drives the condom to move down and then up, so as to reduce friction with the condom and avoid the condom flipping during the process of the turntable 21 transporting the condom, thereby affecting the position state of the condom when it reaches the end of the stroke.

[0045] In addition, two baffles 24 are provided on the frame 6 near the turntable 21 and facing the second loading unit 3. A vertical channel for transporting condoms is formed between the two baffles 24. The second loading unit 3 can absorb condoms in the vertical channel. The setting of the vertical channel reduces the "noise" introduced by ambient light when the recognition unit is working, which is beneficial to improving the recognition effect of the recognition unit.

[0046] The identification unit is arranged on the frame 6, and the identification unit includes a camera, which faces the vertical channel. The identification unit is used to identify the grabbing position of the material picking position 22 on the condom when the condom is at the end of its stroke, and send a signal to the external controller; in this embodiment, the identification unit adopts image recognition technology, and determines the position of a specific condom in space by analyzing the image, and then obtains the grabbing position of the material picking position 22 on the condom, which facilitates the second loading unit 3 to grab at the set position, wherein the identification unit identifies the grabbing position of the material picking position 22 on the condom is a prior art, and those skilled in the art can select it according to needs, which will not be repeated here.

[0047] The second loading unit 3 includes a second suction member and a second suction drive. In this embodiment, the second suction member includes a second hollow rod, a lower end of the second hollow rod is provided with a second suction nozzle, and an upper end of the second hollow rod is connected to a vacuum pump.

[0048] The transfer unit 5 includes a beam 51, a cantilever 52 and a transfer drive. Figure 1As shown, a plurality of vertical slide rails are fixedly connected to the crossbeam 5, a plurality of second hollow rods are slidably arranged on the vertical slide rails at corresponding positions up and down, a second suction drive is fixedly arranged on the slide rail and can drive the second hollow rod to slide up and down along the vertical slide rail, a cantilever 52 is fixedly arranged on the frame 6, the crossbeam 51 is slidably connected to the cantilever 52 front and back, a transfer drive is fixedly arranged on the frame 6 and can be moved away from the transfer unit 2 under the action of the transfer drive to transport the sucked condoms to the electric inspection machine 100, the electric inspection machine 100 is a prior art and will not be described herein.

[0049] The second suction drive is electrically connected to the controller, and the controller is designed to set the sliding stroke of the second suction member along the vertical slide rail according to the grabbing position of the material taking position 22 on the condom when the condom is at the end of the stroke of the transfer unit 2, so that the second suction member grabs the condom at the set position, and after grabbing, the condom naturally droops with the opening facing downward. Figure 6 shown.

[0050] In this embodiment, a background plate (not shown) is further included. The background plate is fixed on the frame 6 and is arranged to face the recognition unit to facilitate the recognition unit to recognize the condom by image. The background plate is made of a color with lower brightness, such as black, which has a large brightness difference with the color of the condom, which is beneficial to improving the accuracy of the recognition result. At the same time, it can also reduce the degree of ambient light entering the recognition area of ​​the recognition unit, which is also beneficial to improving the accuracy of the recognition result.
