Description

Technical Field

[0001] The utility model relates to the technical field of soft bag detection, in particular, to a soft bag body unobstructed clamping device. In addition, the utility model also relates to a soft bag detection device comprising the soft bag body unobstructed clamping device. Background Art

[0002] In the pharmaceutical industry, medical infusion soft bags are commonly used packaging containers for liquid medicines. However, due to production environment or production process, some tiny foreign matter such as aluminum chips, glass chips, rubber chips, fibers or insoluble drugs may be mixed into the soft bags. During intravenous infusion, these foreign matter may enter the human body with the liquid medicine, causing blood vessel blockage, seriously affecting the patient's life and health. Therefore, in the production process of soft infusion bags, the liquid medicine in the soft infusion bags needs to be checked for foreign matter one by one, and soft bag detection equipment such as automatic foreign matter inspection machines are essential quality inspection equipment in the inspection process. When the soft bag detection equipment is performing foreign matter detection on the soft infusion bag, it is necessary to rotate the soft infusion bag to be detected at high speed so that the liquid medicine in the soft infusion bag rotates under the action of inertia, and then take high-speed sequence images, and then compare the trajectory changes of the foreign matter in the sequence images to determine whether there is a foreign matter in the liquid medicine.

[0003] However, since the soft bag is easily deformed during the rotation process, during the detection process, the soft bag needs to be reliably fixed in the detection equipment through a clamping device, and at the same time, the clamping device should avoid affecting the detection accuracy of the detection equipment for the soft bag. For example, Chinese utility model patent CN219122073U discloses a soft bag foreign body detection device without dead angles, which uses a transparent splint to clamp the bottom of the soft bag so that the liquid at the bottom of the soft bag can flow upward. However, since the soft bag needs to be sterilized in a water bath after preparation, there will be more water droplets on the bag when the soft bag comes out of the sterilization cabinet. If a splint is used to clamp the bottom of the soft bag, there will be water marks on the splint and the surface bracket of the soft bag, so that when foreign matter is detected, the trajectory of the water marks in the picture taken will seriously affect the detection results. And if used for a long time, the splint will be dirty, and the dirt will block the soft bag to be detected, which will also cause false detection and affect the detection results. At the same time, when the soft bag is rotating at high speed, if there is a foreign object sandwiched in the gap formed by the two films of the bag body, black stripes will be formed at the junction of the films during lighting inspection, which will interfere with the detection of the foreign object and thus affect the detection results.

The first bag body clamping portion and the second bag body clamping portion are correspondingly arranged and used for abutting and cooperating with each other to clamp the bag body edge of the soft bag.

[0010] Further, the first clamping assembly includes a first support clamping arm and a driving roller rotatably disposed on the first support clamping arm and connected to the first clamping block, and the first detection channel is opened on the driving roller.

[0011] Further, the second clamping assembly includes a second support clamping arm, a sliding member slidably disposed on the second support clamping arm and connected to the driving end of the clamping driving assembly, and a driven roller rotatably disposed on the sliding member and connected to the second clamping block, and the second detection channel is opened on the driven roller.

Specifically, the clamping drive assembly 300 drives the first clamping assembly 100 and the second clamping assembly 200 to be relatively close, so that the head clamping portion 1 420 and the head clamping portion 2 abut against each other to clamp the head of the soft bag in the clamping groove 1 430 and the clamping groove 2.

[0033] like Figure 3 and Figure 4As shown, in this embodiment, the first clamping block 400 includes a tail clamping portion 1 440 formed by extending the edge of the detection port 1 410 toward the direction close to the second clamping block 500, and the second clamping block 500 includes a tail clamping portion 2 formed by extending the edge of the detection port 2 toward the direction close to the first clamping block 400. The tail clamping portion 1 440 and the tail clamping portion 2 are arranged correspondingly and used to abut and cooperate with each other to clamp the tail edge of the soft bag. Specifically, the first clamping assembly 100 and the second clamping assembly 200 are driven relatively close by the clamping drive assembly 300, so that the tail clamping portion 1 440 and the tail clamping portion 2 abut and cooperate to clamp the tail edge of the soft bag. Optionally, the tail clamping portion 1 440 and the tail clamping portion 2 are made of transparent material, so that after clamping the tail edge of the soft bag and clamping the two films of the soft bag body, foreign matter in the gap of the soft bag can be detected.

[0034] In this embodiment, the first clamping block 400 includes a bag body clamping portion 1 formed by extending the edge of the detection port 1 410 toward the direction close to the second clamping block 500, and the second clamping block 500 includes a bag body clamping portion 2 formed by extending the edge of the detection port 2 toward the direction close to the first clamping block 400. The bag body clamping portion 1 and the bag body clamping portion 2 are arranged correspondingly and used to abut and cooperate with each other to clamp the edge of the bag body of the soft bag. Specifically, the first clamping assembly 100 and the second clamping assembly 200 are driven relatively close by the clamping drive assembly 300, so that the bag body clamping portion 1 and the bag body clamping portion 2 abut and cooperate to clamp the edge of the bag body of the soft bag, thereby clamping the two films of the bag body of the soft bag, eliminating black stripes, and improving the detection accuracy. Optionally, the bag body clamping portion 1 and the bag body clamping portion 2 are made of transparent material, so that after clamping the edge of the bag body of the soft bag and clamping the two films of the bag body of the soft bag, foreign objects in the gap of the soft bag can be detected.

[0035] like Figure 2 As shown, in this embodiment, the first clamping assembly 100 includes a supporting clamp arm 110 and an active roller 120 rotatably arranged on the supporting clamp arm 110 and connected to the first clamp block 400, and the detection channel 1 is opened on the active roller 120. Specifically, the active roller 120 is installed by the supporting clamp arm 110, and then actively rolls and rotates to drive the soft bag to rotate at a high speed. Optionally, the active roller 120 is rotatably arranged on the supporting clamp arm 110 through a bearing.

[0036] like Figure 2As shown in the figure, in this embodiment, the second clamping assembly 200 includes a second support clamping arm 210, a sliding member 220 slidably disposed on the second support clamping arm 210 and connected to the driving end of the clamping driving assembly 300, and a driven roller 230 rotatably disposed on the sliding member 220 and connected to the second clamping block 500. A second detection channel is formed on the driven roller 230. Specifically, by installing the sliding member 220 on the second support clamping arm 210 and then installing the driven roller 230 through the sliding member 220, the driving end of the clamping driving assembly 300 is used to drive the sliding member 220 to slide relative to the second support clamping arm 210, so that the driven roller 230 approaches or moves away from the driving roller 120, thereby enabling the first clamping block 400 and the second clamping block 500 to approach or move away from each other to clamp or release the flexible bag. Optionally, pin holes are formed on the main body roller, and pins for plugging and mating with the pin holes are arranged on the driven roller 230. When the driven roller 230 approaches the driving roller 120, the pins are inserted into the pin holes, so that when the driving roller 120 rotates, the driven roller 230 is synchronously driven to rotate, thereby driving the flexible bag to rotate. Optionally, the driven roller 230 is rotatably disposed on the sliding member 220 through a bearing.

[0037] As Figure 2 shown in the figure, in this embodiment, a buffer structure for applying an elastic force to the driven roller 230 for elastic buffering when clamping the flexible bag is provided on the sliding member 220. Specifically, when the first clamping block 400 and the second clamping block 500 clamp the flexible bag, the buffer structure applies an elastic force to the driven roller 230, and then applies an elastic force to the flexible bag to perform elastic buffering on the flexible bag, so as to avoid clamping and bursting the flexible bag with a large filling amount or a bulging bag, and at the same time ensure that the flexible bag with a small filling amount can be clamped under the action of the elastic force.

[0038] It should be understood that through buffer clamping, it is also beneficial for the first clamping block 400 and the second clamping block 500 to reliably clamp the flexible bag.

When the clamping drive assembly 300 drives the sliding member 220 to move towards the direction close to the first clamping assembly 100 and the first clamping block 400 and the second clamping block 500 clamp the soft bag, the elastic member applies an elastic force to the sliding portion 241, and then transmits it to the soft bag through the driven roller 230 and the second clamping block 500, thereby performing elastic buffering on the soft bag.

[0040] As Figure 2 shown in the figure, in this embodiment, the elastic member includes a guide rod 243 movably passing through the support plate 242 to be connected to the sliding portion 241, and a buffer spring 244 sleeved on the guide rod 243 and abutting against the support plate 242 and the sliding portion 241 respectively. Optionally, when the sliding portion 241 drives the driven roller 230 to clamp the soft bag, the generated reaction force causes the buffer spring 244 to undergo elastic deformation, and then generates an elastic force to perform elastic buffering on the soft bag. Optionally, in another embodiment, the elastic member is a buffer cylinder fixedly disposed on the sliding portion 241 and having a movable end connected to the driven roller 230. Optionally, in another embodiment, the elastic member includes a gas spring fixedly disposed on the sliding portion 241 and having a movable end connected to the driven roller 230. Optionally, in another embodiment, the structures of the first clamping assembly 100 and the second clamping assembly 200 are the same or similar to achieve double-buffer clamping of the soft bag. Optionally, there are multiple driving rollers 120, and the multiple driving rollers 120 are arranged at intervals on the supporting clamping arm 110. The driving rollers 120 and the driven rollers 230 are arranged in one-to-one correspondence, and the multiple driven rollers 230 are arranged at intervals on the sliding member 220 to simultaneously perform buffer clamping on multiple soft bags.

[0041] As Figure 5 shown in the figure, the soft bag detection device of this embodiment includes the above-mentioned soft bag body unobstructed clamping device. Specifically, by using the above-mentioned soft bag body unobstructed clamping device in the soft bag detection device to clamp and fix the soft bag, the soft bag body is unobstructed during the detection process, and the influence of water marks, dirt, and black stripes on the detection result is eliminated, the detection accuracy is improved, the practicability is strong, and it is suitable for wide promotion and application.

[0042] As Figure 6As shown, optionally, the soft bag detection device further includes a rotation drive assembly for driving the active roller 120 to rotate. The rotation drive assembly includes a rotation drive member 610 and a worm and worm gear 620 that is connected to the output end of the rotation drive member 610 and is in gear engagement with the active roller 120. Optionally, the rotation drive member 610 is a servo motor. It should be understood that the specific structure of the servo motor belongs to the well-known technology of those skilled in the art and will not be elaborated here. Optionally, the soft bag detection device further includes a mounting platform 700 and a plurality of soft bag body unobstructed clamping devices, and the plurality of soft bag body unobstructed clamping devices are arranged at intervals on the mounting platform 700.
