[0002] In industries such as pharmaceuticals, there are products where the drugs are pre-filled into syringes; these are called pre-filled syringes.

[0003] To ensure quality, pre-filled needles need to undergo light inspection to check for impurities or appearance defects, which requires a light inspection machine. However, pre-filled needles are usually fed into a perforated tray, which is placed in a hopper. Before entering the light inspection machine, the pre-filled needles need to be removed from the hopper and neatly fed into the machine. Existing methods mostly rely on manual labor for removal, resulting in low work efficiency. Therefore, an automatic hopper removal device is needed. Utility Model Content

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] In one embodiment, such as Figures 1-3 As shown, the detachment device of a pre-charged needle lamp inspection machine in this embodiment includes a frame 1, a conveyor belt 2 fixedly installed inside the frame 1, a robotic arm material picking device 3 fixedly installed on one side of the conveyor belt 2, and a slide merging mechanism 4 configured on the other side of the conveyor belt 2. The slide merging mechanism 4 includes a primary slide 401 consisting of several inclined parallel slides, a stop cylinder 402, a secondary slide 403 consisting of several inclined slides with gradually approaching exits, a rotatable swing branch 405 driven by a servo motor 404, and a single-channel tertiary slide 406.

[0017] In this embodiment, the material hopper device transported by the conveyor belt 2 includes a material hopper body, a material tray, and pre-charge needles neatly inserted into the material tray. The material hopper body serves as the loading shell, and the material tray containing the pre-charge needles is placed inside the material hopper body. It is directly transported by the conveyor belt 2. When the material hopper device is transported to a suitable position, the robotic arm material handling device 3 removes the material tray and its loaded pre-charge needles from the material hopper body. Then, the pre-charge needles are removed from the material tray and placed into the slide merging mechanism 4. They then pass through the first-level slide 401 and the stop cylinder 402 of the slide merging mechanism 4 to enter the second-level slide 403. Finally, they pass through the rotatable swing branch 405 driven by the servo motor 404 to enter the third-level slide 406. During this process, the pre-charge needles undergo double rectification and can enter the light inspection machine in the set order through the third-level slide 406 for light inspection.

[0018] As one implementation method, such as Figure 1 and Figure 5 As shown, a transfer lifting platform 5 is also fixedly installed inside the frame 1. The transfer lifting platform 5 includes a material tray positioning frame 501, a lifting cylinder 502, and an offset cylinder 503. The lifting cylinder 502 is slidably installed below the material tray positioning frame 501 and is fixedly connected to the movable end of the offset cylinder 503. The movable end of the lifting cylinder 502 faces the bottom end of the material tray positioning frame 501 and is equipped with a top bar 504. The slide confluence mechanism 4 is configured and installed on the upper side of the transfer lifting platform 5.

[0019] like Figure 1 and Figure 4 As shown, the robotic arm material handling device 3 includes a robotic arm 301, a suction cylinder 302 fixedly connected to the movable end of the robotic arm 301, a suction cup 303 fixedly connected to the movable end of the suction cylinder 302, and a material handling fork 304 adapted to be installed between the suction cups 303.

[0020] In this embodiment, the robotic arm 301 is a conventional automated robotic arm in the prior art. It can drive the suction cylinder 302, suction cup 303 and picking fork 304 at its movable end to perform multi-axis free movement. The suction cup 303 of the robotic arm picking device 3 can adsorb and grab the material tray loaded in the material nest body under the action of the suction cylinder 302, and place it in the material tray positioning frame 501 of the transfer lifting platform 5. Then, the lifting cylinder 502 extends and drives the top bar 504 to move upward, lifting the pre-filled needle loaded in the material tray. Then, the picking fork 304 of the robotic arm picking device 3 moves horizontally from below the lip of the pre-filled needle and inserts into the gap between the pre-filled needles. Then, the picking fork 304 is lifted to pull the lifted pre-filled needle out of the material tray and move it to the first-stage slide 401 of the slide merging mechanism 4.

[0021] Further details, such as Figure 5 As shown, in order to further ensure the stability of the picking fork 304's picking operation, the top bar 504 is arranged in an intermittent manner compared to the pre-filled pins placed in the tray, such as a vertical arrangement of one, three, five, seven, and nine. That is, the upward displacement of the top bar 504 can lift the pre-filled pins neatly placed in the tray in an intermittent manner to facilitate the picking operation of the picking fork 304. After the current picking operation is completed, the offset cylinder 503 drives the lifting cylinder 502 and the top bar 504 to offset, thereby changing the lifting position of the top bar 504 to a vertical arrangement of two, four, six, eight, and ten. Then, when the lifting cylinder 502 is driven, the top bar 504 can lift the remaining vertical pre-filled pins to facilitate the picking operation of the picking fork 304 again.

[0022] The specific collaborative steps of the robotic arm material handling device 3 and the slide merging mechanism 4 are as follows: After the robotic arm 301 drives the material handling fork 304 to align several rows of pre-charged needles with the entrance of the first-level slide 401, the robotic arm 301 drives the material handling fork 304 to rotate around the entrance of the first-level slide 401 until the material handling fork 304 tilts, and the pre-charged needles on it naturally slide into the first-level slide 401 until they reach the stop cylinder 402. Then, the stop cylinder 402 retracts, and the pre-charged needles naturally slide into the second-level slide 403 until they reach the swing branch 4. 05. The swing siding 405 is configured with a channel. The servo motor 404 drives it to align with a certain channel of the secondary slide 403. The pre-charge needle in this channel will naturally slide down the swing siding 405 to the tertiary slide 406 until it enters the light inspection machine below. The other secondary slides 403 will be blocked by the side edge of the swing siding 405. With different stopping angles of the servo motor 404, the swing siding 405 will be aligned with different channels of the secondary slide 403 in sequence, so that all the pre-charge needles inside will enter the tertiary slide 406 in sequence.

[0023] As one implementation method, such as Figure 1 and Figure 2 As shown, a material nest positioning device 6 is installed in the frame 1 near the end of the conveyor belt 2. The material nest positioning device 6 includes a positioning fork 602 driven by a positioning cylinder 601 and a separating cylinder 603 for separating the material nests. In this embodiment, when the material nest device is transported to a suitable position by the conveyor belt 2, the positioning fork 602 will perform a limiting positioning operation on the material nest device under the drive of the positioning cylinder 601 to ensure that each material nest can accurately stop at the end of the conveyor belt 2 in sequence. At the same time, the separating cylinder 603 can block subsequent material nests when there are already material nests at the end of the conveyor belt 2 to ensure that multiple material nests will not collide.

[0024] As one implementation method, such as Figure 1 and Figure 7 As shown, a lifting mechanism 7 is also installed on one side of the robotic arm material handling device 3 inside the frame 1. The lifting mechanism 7 includes a lifting platform 701 and a lead screw motor 702 for driving the vertical displacement of the lifting platform 701. In this embodiment, the lifting platform 701 can move up and down along its vertical direction under the drive of the lead screw motor 702. As one implementation method, such as Figure 1 and Figure 3 As shown, a pushing device 8 is installed at the end of the conveyor belt 2 within the frame 1. The pushing device 8 includes a baffle 801 and a push plate 802, as well as a pushing motor 803 for driving the push plate 802 to move. The baffle 801 is fixedly installed on the frame 1, facing the end of the conveyor belt 2. The push plate 802 is slidably connected to one side wall of the baffle 801 under the drive of the pushing motor 803. The movable position of the push plate 802 corresponds to the lifting platform 701. In this embodiment, The baffle 801 can block the material hopper device that is being transported to the end of the conveyor belt 2 to prevent it from falling. After the robotic arm material picking device 3 removes the material tray, the pusher motor 803 drives the pusher plate 802 to push the remaining empty material hopper onto the lifting platform 701. After the robotic arm material picking device 3 picks up the empty material tray that has been removed from the pre-filled needle in the material tray positioning frame 501 and puts it back into the empty material hopper, the screw motor 702 drives the lifting platform 701 to carry the material hopper and the empty material tray for the upward operation. As one implementation method, such as Figure 1 and Figure 7 As shown, a return transfer conveyor belt 9 is adapted to be installed on the top of the lifting mechanism 7 on the frame 1, and a return cylinder 10 is adapted to be installed on the top of the lifting mechanism 7 to push the empty nests on the lifting platform 701 onto the return transfer conveyor belt 9; when the lifting platform 701 moves the nests and empty material trays to the top of the return transfer conveyor belt 9, the return cylinder 10 pushes the nests and empty material trays onto the return transfer conveyor belt 9, and the return transfer conveyor belt 9 transports the empty nest device back to the rear return machine.
