Description

TECHNICAL FIELD

[0001] The application relates to the technical field of glue dispensing equipment, in particular to a glue wiping mechanism and a glue dispensing device. BACKGROUND

[0002] The subcutaneous implant contraceptive (subcutaneous implant) is also called a levonorgestrel silicone rod, is a rod-shaped slow-release system composed of synthetic progestin and silicone rubber, is implanted subcutaneously, and slowly releases every day to play a contraceptive role.

[0003] In the specific production and manufacturing process of the silicone rod, the levonorgestrel drug core capable of playing a contraceptive role is loaded into the inner core of the silicone rod, and then the two ends of the silicone rod are sealed by an adhesive. At present, when the two ends of the silicone rod are sealed by the adhesive, a method of arranging a glue dispensing device at the two ends of the silicone rod is usually adopted, and then a glue dispensing and sealing operation is performed on the two ends of the silicone rod.

[0004] However, in the above related technology, because the glue has very strong adhesion, the needle head used for glue dispensing will have residual glue after the glue dispensing device works for a period of time. The residual glue will quickly solidify at room temperature, and the accumulation on the needle head will cause the needle head to be easily blocked, thereby affecting the glue dispensing precision and subsequent continuous use, so that the residual glue on the glue dispensing needle head needs to be removed. SUMMARY

[0005] In order to remove the residual glue on the glue dispensing needle head, the application provides a glue wiping mechanism and a glue dispensing device.

[0006] The glue wiping mechanism provided by the application adopts the following technical scheme:

[0007] A glue wiping mechanism, comprising a wiping assembly and a pressing assembly, the wiping assembly comprising a cloth releasing wheel, a cloth collecting wheel and a wiping cloth for wiping the needle head, one end of the wiping cloth being arranged on the cloth releasing wheel and the other end being arranged on the cloth collecting wheel, the cloth releasing wheel and the cloth collecting wheel being connected with a rotary driving member, the rotary driving member being used for driving the corresponding cloth releasing wheel or cloth collecting wheel to rotate intermittently;

[0008] The pressing assembly is located between the cloth releasing wheel and the cloth collecting wheel, the pressing assembly is arranged on one side of the wiping cloth, the pressing assembly comprises a downward pressing driving member and a first pressing plate, the first pressing plate is arranged on the upper side of the wiping cloth and the first pressing plate is connected with the output shaft of the downward pressing driving member, when the downward pressing driving member moves downward, the first pressing plate can bend the wiping cloth.

[0009] By adopting the technical scheme, when the glue injection needle head moves to contact the wiping cloth during the process that the wiping cloth is transferred from the cloth releasing wheel to the cloth collecting wheel, the first pressing plate is driven to move downward by the downward driving element. Since the wiping cloth is pulled tight by the cloth releasing wheel and the cloth collecting wheel, the wiping cloth is pressed and bent by the first pressing plate during the downward movement, so that the wiping cloth wraps the glue injection needle head, thereby wiping the glue injection needle head.

[0010] Therefore, during the next glue injection, the glue injection needle head is less likely to have excessive glue remaining, thereby preventing the needle head from being blocked, and thus ensuring the glue injection precision.

[0011] Optionally, the material pressing assembly further comprises a second pressing plate, the second pressing plate is arranged below the first pressing plate, a first pressing groove is arranged on the side of the first pressing plate facing the second pressing plate, and the first pressing groove is arranged through the side of the first pressing plate;

[0012] A second pressing groove is arranged on the side of the second pressing plate facing the first pressing plate, the second pressing groove is arranged through the side of the second pressing plate, and the first pressing groove and the second pressing groove are oppositely arranged;

[0013] When the first pressing plate is pressed to contact the second pressing plate, the first pressing groove and the second pressing groove jointly form a through groove for the needle head to pass through.

[0014] By adopting the technical scheme, when the glue injection needle head enters the second pressing groove of the second pressing plate from both sides of the material pressing assembly during the glue wiping, when the first pressing plate moves downward and is buckled with the second pressing plate, the through groove formed by the first pressing plate and the second pressing plate wraps the glue injection needle head, so that when the glue injection needle head leaves the through groove, the glue is also taken away by the wiping cloth under the action of the friction force, thereby achieving the effect of wiping and removing the glue block.

[0015] Optionally, the glue wiping mechanism comprises a first glue wiping station and a second glue wiping station, the cloth releasing wheel and the cloth collecting wheel are both arranged on the first glue wiping station at intervals, a cloth guiding wheel is arranged on the second glue wiping station, and the wiping cloth moves from one side of the material pressing assembly to the other side along the order of the cloth releasing wheel, the cloth guiding wheel and the cloth collecting wheel.

[0016] The first pressing groove is arranged through both sides of the first pressing plate, the second pressing groove is arranged through both sides of the second pressing plate, and both ends of the first pressing groove and the second pressing groove are arranged towards the wiping cloth, respectively.

[0017] By adopting the above technical solution, since both ends of the silicone tube need to be glued during the actual glue dispensing process, glue injection assemblies are installed at both ends of the silicone tube. When the wiping cloth moves from the first glue wiping station to the second glue wiping station in the above order, the glue injection assemblies on both sides of the pressing assembly at the second glue wiping station correspond to the glue injection assemblies at both ends of the silicone tube. Therefore, the glue injection needles on both sides can be inserted into the corresponding through grooves, thereby achieving the purpose of wiping the glue block. By providing a single glue wiping mechanism, two sets of glue injection needles can be wiped simultaneously, thus saving processing costs.

[0018] Optionally, a cloth pressing assembly is further provided on the first glue wiping station, and the cloth pressing assembly is located between the cloth placing wheel and the material pressing assembly. The cloth pressing assembly includes a first cloth pressing wheel, a second cloth pressing wheel and a pressing member. The first cloth pressing wheel and the second cloth pressing wheel are arranged at intervals, and the wiping cloth moves along the surface of the first cloth pressing wheel. One end of the pressing member is connected to the second cloth pressing wheel, and the other end abuts against the side of the wiping member away from the first cloth pressing wheel.

[0019] By adopting the above technical solution, the cloth pressing assembly is used to adjust the tension of the wiping cloth between the cloth placing wheel and the cloth collecting wheel, so that it is not too tight to bend, nor too loose to lack wiping force.

[0020] Optionally, a glue frame is provided on the upper side of the first pressing plate, and the glue frame is provided with an opening, and the opening is opened in a direction away from the first pressing plate.

[0021] By adopting the above technical solution, the glue frame is used to collect excess glue dripping from the glue injection needle when not dispensing glue, improving the phenomenon of glue dripping and splattering everywhere, thereby reducing glue waste and improving the cleanliness of the work station, while reducing the possibility of related instruments being corroded by glue and affecting their own performance.

[0022] Optionally, the two groups of pressing components, whose opposite sides are separated, are used as a glue erasing area, and their adjacent sides are used as a glue removal area. A glue removal component is provided in the glue removal area, and the glue removal component includes a liquid storage box and a plurality of alkali liquid nozzles. The liquid storage box is located at the upper end of the first pressing plate, and the liquid storage box is arranged along the length direction of the first pressing plate. Each of the alkali liquid nozzles is connected to the liquid storage box through an alkali liquid pipe.

[0023] Each of the alkali solution nozzles is a bidirectional nozzle, and each of the alkali solution nozzles is arranged toward the wiping cloths on both sides.

[0024] By adopting the above technical solution, when the wiping cloth runs from the glue wiping area on one side of the pressing assembly to the glue removal area on the other side, the glue injection needle extending into the through groove is wiped in the glue wiping area, and the glue on the wiping cloths on both sides is dissolved simultaneously by the bidirectional alkaline liquid nozzle in the glue removal area, so that the wiping cloths can be recycled and reused.

[0025] Optionally, each of the first pressure plates is connected to a scraper on one side close to the glue removal component, the scraper is arranged along the height direction of the first pressure plate, and the lower end of the scraper is arranged toward the corresponding direction of the wiping cloth. A waste liquid frame is also provided in the glue removal area, and the waste liquid frame is arranged opposite the wiping cloth on both sides of the scraper.

[0026] By adopting the above technical solution, when the first pressing plate moves downward, it drives the scraper to move downward and wipes the wiping cloth, thereby wiping off the glue liquid together with the alkali liquid, and the waste liquid frame collects the glue liquid.

[0027] In a second aspect, the present application further discloses a glue dispensing device, comprising a glue wiping mechanism and a glue dispensing mechanism, wherein the glue dispensing mechanism comprises a material transfer assembly and a glue injection assembly, wherein the material transfer assembly is arranged on a side of the second glue wiping station away from the first glue wiping station, wherein the material transfer assembly comprises a carrier assembly, wherein the carrier assembly comprises a material discharge tray, wherein a plurality of placement slots are provided on the material discharge tray, and wherein the placement slots are arranged on both sides of the material discharge tray;

[0028] There are several glue injection components, and the glue injection components are arranged outside the discharge tray near the two ends of the placement slot. Each group of the glue injection components includes a glue barrel and a glue injection needle. One end of the glue injection needle is connected to the corresponding glue barrel, and the other end is arranged toward the corresponding placement slot.

[0029] By adopting the above technical solution, the silicone tube to be glued is placed in the placement groove. The glue injection needle extends from the notches at both ends of the placement groove into the placement groove and glue is applied near the ends of the silicone tube. After the glue injection assembly glues the silicone tube in turn, the glue wiping mechanism wipes away any residual glue on the glue injection needle.

[0030] Optionally, the dispensing mechanism further includes a clamping jig assembly and a moving mechanism for controlling the movement of the glue injection component, and the moving mechanism includes a first moving unit, a second moving unit, and a third moving unit;

[0033] By adopting this technical solution, the clamping jig assembly has multiple clamping parts, each of which clamps a corresponding glue injection component to apply glue to both ends of the silicone tube. The first, second, and third mobile units respectively drive the clamping jig assembly in the X, Y, and Z directions, causing the glue injection component to reciprocate between the glue dispensing and wiping stations, allowing the glue dispensing and wiping operations to be performed alternately.

[0034] Optionally, the dispensing mechanism further includes a control system, the control system including a shooting unit, a calculation unit and an adjustment unit, the shooting unit being arranged on the clamping jig assembly and facing the discharge tray;

[0035] The adjusting unit is electrically connected to the first moving unit, the second moving unit and the third moving unit, and the shooting unit, the calculating unit and the adjusting unit are electrically connected in sequence.

[0037] In summary, this application has at least one of the following beneficial effects:

[0038] 1. Under the joint action of the pressing component of the glue-wiping mechanism and the wiping cloth, the wiping cloth wraps the glue injection needle under the action of external force. When the glue injection needle is recovered, the wiping cloth wipes the glue liquid or glue block remaining on the glue injection needle under the action of friction, so that it is not easy for the glue injection needle to retain too much glue and the needle is not easy to be blocked, which is conducive to ensuring the dispensing accuracy.

[0039] 2. By setting up a set of glue wiping mechanisms, two sets of glue injection needles can be wiped at the same time, thus saving processing costs.

[0040] 3. When the wiping cloth runs from the glue wiping area on one side of the pressing assembly to the glue removing area on the other side, the glue injection needle extending into the through groove is wiped in the glue wiping area. In the glue removing area, the glue on the wiping cloths on both sides is dissolved simultaneously by the bidirectional alkaline solution nozzle, so that the wiping cloths can be recycled and reused.

[0041] 4. The first moving unit, the second moving unit and the third moving unit respectively drive the clamping jig assembly to move along the X, Y and Z directions, so that the glue injection component moves back and forth between the glue dispensing station and the glue wiping station, so that the glue dispensing work and the glue wiping work are performed alternately.

[0042] 5. The control system accurately calculates the moving distances of the first moving unit, the second moving unit, and the third moving unit, thereby improving the dispensing accuracy of the dispensing. BRIEF DESCRIPTION OF THE DRAWINGS
