Description

Technical Field

[0001] This application relates to the field of medical injection molded parts technology, specifically to a method and system for automatically applying labels to medical injection molded parts. Background Technology

[0002] In the production process of medical injection molded parts, multiple medical injection molded parts are often molded as a single piece and bonded together to form a single injection molding unit. To facilitate packaging, transportation, and subsequent automated operations, multiple injection molding units are then assembled into a complete medical injection molded part module.

[0003] Currently, label application for such medical injection-molded modules mainly relies on manual operation or semi-automatic equipment. In related technologies, operators typically manually apply labels to designated surfaces of the module, followed by folding and tidying the labels in subsequent processes. However, this manual or semi-automatic method has the following problems: manual application makes it difficult to ensure precise alignment between the label and the application surface; it easily generates air bubbles or wrinkles, affecting the application quality and product appearance; the unstable application effect results in limited auxiliary fixing effect of the label on multiple injection-molded units, causing multiple injection-molded units to easily separate during subsequent transportation, affecting the overall integrity of the product; furthermore, when it is necessary to separate injection-molded units, the existing label structure design makes the tearing operation inconvenient, increasing the difficulty of use.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] Figure 1 The diagram shows the steps of an automatic labeling method for medical injection molded parts according to an embodiment of this application. This application provides an automatic labeling method for medical injection molded parts; in one embodiment, as shown... Figure 1 As shown, the method includes: Step 101: Identify the module parameters of the medical injection molded part module.

[0031] In this step, the medical injection molded part module includes multiple injection molding units. Each injection molding unit is composed of multiple medical injection molded parts, and these multiple injection molding units are then assembled into a medical injection molded part module. The multiple medical injection molded parts are integrally molded and bonded together to form a single injection molding unit, while the multiple injection molding units are not bonded together.

[0032] Step 102: Grab the medical injection molded part module, move it above the bonding station, and switch to the set tilt angle.

[0033] In this step, multiple injection molding units are assembled to form a medical injection molded part module. A robotic arm picks up the entire module and moves it above the application station. The robotic arm's rotation angle is controlled to tilt the entire module at a set angle, creating a tilt angle between the application surface and the horizontal plane. This tilt angle can be selected from 5° to 30°.

[0034] Step 103: Control the label output machine to output labels with corresponding parameters according to the module parameters.

[0035] In this step, the label includes an adhesive area and a non-adhesive area. The adhesive area is used to bond with the application surface. The output surface of the label output machine is horizontal, and a drive roller is located at the end of the output surface. The label passes over the drive roller. Based on the module parameters, the area size of the application surface of the medical injection molded part module can be determined, thereby outputting a label of the corresponding size so that the area size of the adhesive area is equal to the area size of the application surface.

[0036] Step 104: Align the edge of the adhesive surface of the medical injection molded part module with the edge of the adhesive surface of the adhesive area and attach them together.

[0037] Step 105: Move the medical injection molding module diagonally downwards at a set tilt angle, so that the bonding surface and the adhesive surface of the adhesive area of ​​the medical injection molding module gradually press together over the drive roller.

[0038] In this step, due to the set tilt angle, the bonded and unbonded areas of the label's adhesive region are at an angle to each other as the label moves downwards at an angle. The drive roller effectively lifts the label upwards, ensuring that the adhesive region passing over the drive roller adheres tightly and completely to the bonding surface of the medical injection molding module, preventing air bubbles caused by loose bonding. This step is the first bonding process; the edges of both are already bonded. The medical injection molding module slides downwards at an angle, carrying the label downwards with it. During this downward movement, the label output machine does not apply any tension to the label. The adhesive region of the label also provides auxiliary fixation between multiple injection molding units, further preventing them from separating.

[0039] Step 106: Move the medical injection molded part module carrying the label to the first pressing surface of the pasting station, and perform the pasting and pressing process for a first preset time.

[0040] In this step, the robotic arm moves the medical injection molded part module and the label together above the first pressing surface. The robotic arm then moves downwards to press the adhesive surface and the bonding area firmly against the first pressing surface for a first preset time, making the two bond more securely. The first preset time can be determined based on multiple pre-tests of the adhesive surface's tackiness, and is generally set to a value between 1s and 3s for a strong bond.

[0041] Step 107: After the first preset time, move the medical injection molded part module toward the bending station. During the movement, the stop blocks the non-adhesive area, causing the non-adhesive area and the adhesive area to bend together.

[0042] In this step, the stop can be a part of the bending station structure, such as the edge of the bending station. Since the adhesive area is already bonded to the surface, the non-adhesive area droops due to gravity. During movement, the non-adhesive area faces the stop, and the stop partially blocks the non-adhesive area, allowing it to begin bending. Because the adhesive area is bonded to the surface, the bending edge is the boundary between the adhesive and non-adhesive areas. In the output label, the area of ​​the non-adhesive area is smaller than the adhesive area, and the edge of the folded non-adhesive area is within the edge range of the adhesive area. Furthermore, before or during this step, the tilt angle of the medical injection molded part module is adjusted to horizontal, and the bending and pressing are performed downwards at a horizontal angle in the subsequent bending and pressing process.

[0043] Step 108: Move the medical injection molded part module to the second pressing surface of the bending station, and perform a bending and pressing process on the folded non-adhesive area and adhesive area for a second preset time.

[0044] In this step, the robotic arm moves the medical injection molded module and the label together above the second pressing surface. The robotic arm then moves downwards to press the adhesive surface, the glued area, and the bent, non-adhesive area together, ensuring that the adhesive and non-adhesive areas are completely folded together. The second preset time can be determined based on multiple pre-tests of the label's resilience. Generally, a value between 1s and 3s is sufficient to create a sufficiently sharp fold line between the adhesive and non-adhesive areas, preventing either area from returning to its unfolded state.

[0045] Step 109: Move the medical injection molded part module carrying the label to the labeling completion station.

[0046] In this embodiment, by identifying the module parameters of the medical injection molded part module, the label output machine is controlled to output labels of the corresponding size, ensuring that the area of ​​the adhesive region matches the size of the application surface. By setting an inclination angle and moving downwards along the transmission rollers, the label can be tightly and completely adhered to the application surface, effectively avoiding air bubbles caused by loose adhesion. During the application process, the adhesive area of ​​the label plays a supporting role in fixing multiple injection units in the medical injection molded part module, preventing them from separating during subsequent transportation. Combined with the blocking of the stop and bending compression, the non-adhesive area and the adhesive area of ​​the label are folded together. The entire medical injection molded part module is a set of products. When it is needed at the destination, the label needs to be torn off. The entire label can be torn off through the non-adhesive area, and then the multiple injection units can be separated. The non-adhesive area can be printed with identification marks to indicate the category, parameters, etc. of the medical injection molded part module.

[0047] Figure 2 The diagram illustrates the steps of a method for outputting matching tabs. In one embodiment, as shown... Figure 2As shown, step 101 includes: Step 201: Collect image parameters of the medical injection molded part module.

[0048] Step 202: Obtain the preset model of the injection molding unit.

[0049] Step 203: Based on image parameters and preset models, identify the arrangement and number of injection units in the medical injection molded part module.

[0050] Step 103 includes: Step 204: Output matching labels based on the arrangement and number of injection molding units.

[0051] In this embodiment, a preset model is obtained by pre-modeling based on the dimensional parameters of the injection molding unit. By acquiring image parameters of the medical injection molding module and identifying the arrangement and number of injection molding units based on the preset model, a label matching the arrangement and number is output. This ensures that the adhesive area of ​​the label corresponds to the position of each injection molding unit, achieving complete coverage. For example, the injection molding units can be single-row or double-row, with each row including multiple medical injection molding parts. Adjacent medical injection molding parts are interconnected by detachable or cutable plastic, and multiple rows of injection molding units are combined to form a medical injection molding module.

[0052] Figure 3 The diagram illustrates the steps of a method for calculating and setting the tilt angle. In one embodiment, as shown... Figure 3 As shown, prior to step 102, the automatic labeling method for medical injection molded parts further includes: Step 301: Obtain the first horizontal height of the end of the conveyor surface of the label output machine.

[0053] Step 302: Obtain the second horizontal height of the preset tangent point of the drive roller; the drive roller is set adjacent to the end of the conveying surface.

[0054] Step 303: Calculate the reference tilt angle based on the first horizontal height and the second horizontal height, and calculate the set tilt angle based on the reference tilt angle and the preset difference.

[0055] In this embodiment, the position of the transmission roller is set so that the second horizontal height is lower than the first horizontal height.

[0056] Figure 10 The diagram shown illustrates the calculation of the tilt angle. Figure 11 The diagram shows the process of applying labels to a medical injection molded part module. Figure 12 The image shows a schematic diagram of a medical injection molded part module with a partial label attached. Figure 13 The diagram shows the area of ​​the retaining member without adhesive after bending. (Refer to...) Figure 10The preset tangent point 1001 is the tangent point between the transmission roller tangent surface 1003 and the transmission roller 1004 at the end of the conveying surface 1002. The second horizontal height is lower than the first horizontal height. The angle between the line connecting the second horizontal height and the first horizontal height and the horizontal plane is the reference tilt angle. Figure 11 and Figure 12 The adhesive side of the label 1210 faces upward and is conveyed to the transmission roller 1004. The reference tilt angle and the preset difference are added to obtain the set tilt angle. This allows the robotic arm to move the medical injection molded module 1201 diagonally downward along the set tilt angle. The application surface 1202 of the medical injection molded module 1201 only comes into close contact with the label area on the transmission roller 1004 and does not come into contact with other areas of the label. That is, the bonding process only occurs on the transmission roller 1004. The lower position of the transmission roller 1004 forces the bonded and unbonded areas on the label to be at an angle to each other, and makes the label 1210 itself have a certain downward tendency. The transmission roller 1004 is equivalent to lifting the label 1210 upward. The mutual compression between the transmission roller 1004 and the medical injection molded module 1201 allows the adhesive area of ​​the label 1210 to be tightly and completely bonded to the application surface 1202 of the medical injection molded module 1201. The preset difference can be arbitrarily selected from 1° to 10°, so that when the robotic arm grasps and presses the medical injection molded part module 1201 obliquely downward and moves it, the medical injection molded part module 1201 only contacts the transmission roller 1004 and does not contact the end of the conveying surface 1002. (Refer to...) Figure 13 After the adhesive area 1211 is completely pasted, the robotic arm carries the medical injection molding module 1201 toward the bending station 1301. The edge 1302 of the bending station 1301 acts as a stop to block the non-adhesive area 1212, causing the non-adhesive area 1212 and the adhesive area 1211 to bend against each other.

[0057] Figure 4 The diagram illustrates the steps of an edge-aligned bonding method. In one embodiment, as shown... Figure 4 As shown, prior to step 104, the automatic labeling method for medical injection molded parts further includes: Step 401: Control the label output machine to output labels so that the non-adhesive area passes the drive roller until the edge of the adhesive surface of the adhesive area reaches and contacts the drive roller.

[0058] Step 402: Switch the control label output machine to standby mode.

[0059] Step 104 includes: Step 403: Move the adhesive surface of the medical injection molded part module toward the drive roller, so that the edge of the adhesive surface and the edge of the glued surface are pressed against the drive roller.

[0060] In this embodiment, after the edge of the adhesive surface reaches and contacts the drive roller, the medical injection molded part module approaches the label at a set tilt angle. Machine vision and other methods are used to align the edges of the adhesive surface and the label surface, pressing them firmly onto the drive roller. At this time, the label output machine is in standby mode and does not apply force to the label. The robotic arm drives the medical injection molded part module and the label to move diagonally downwards, thereby gradually moving the entire label downwards, until the adhesive surface and the adhesive area gradually bond completely together.

[0061] Figure 5 The diagram illustrates the process of a medical injection molded part module sliding obliquely downwards. In one embodiment, as shown... Figure 5 As shown, step 105 includes: Step 501: Switch the control label output machine to follow-up mode.

[0062] Step 502: Press the transmission roller with the medical injection molded part module under the first preset pressure.

[0063] Step 503: Maintain the first preset pressure and drive the medical injection molding module to slide down at a set speed along a set tilt angle, so that the bonding surface and the adhesive surface of the adhesive area of ​​the medical injection molding module gradually press together over the drive roller.

[0064] In this embodiment, by applying a first preset pressure using a robotic arm, the medical injection molded module and the label can be bonded more firmly to each other. During pre-testing, after the robotic arm grasps the medical injection molded module, it applies it obliquely downwards with a first preset pressure of 0.3~0.5MPa. This pressure range is sufficient to press the adhesive into the microscopic gaps on the surface of the object being bonded, achieving good initial adhesion, while avoiding excessive pressure that could cause the label to wrinkle.

[0065] Figure 6 The diagram illustrates the steps of a method for assisting rotation with a drive roller. In one embodiment, as shown... Figure 6 As shown, step 105 also includes: Step 601: While the medical injection molded part module slides down at a set speed, control the transmission roller to rotate at a set speed as the linear speed.

[0066] Step 602: When the transmission roller travels the length of the adhesive area on the outer circumference of the transmission roller, control the transmission roller to stop rotating.

[0067] In this embodiment, the set speed includes a direction vector. As the robotic arm moves the medical injection molded part module downwards at a set speed, the transmission roller rotates at the same linear velocity, thereby assisting in the transmission of the label and preventing relative friction between the transmission roller and the label from causing label displacement and incomplete adhesion.

[0068] Figure 7The diagram illustrates a heating method during compression. In one embodiment, as shown... Figure 7 As shown, the automatic labeling method for medical injection molded parts also includes: Step 701: When performing the pasting and pressing process, control the temperature of the first pressing surface of the pasting station to switch to the first preset temperature range.

[0069] Step 702: When performing the bending and pressing process, control the temperature of the second pressing surface of the bending station to switch to the second preset temperature range.

[0070] In this embodiment, heating resistance wires can be provided at the bottom of the first and second pressing surfaces to heat them. Heating further improves the adhesion during the pasting and pressing process, and during the bending and pressing process, heating softens the label when it is bent, optimizing the bending effect. Setting the first preset temperature range to a value between 25℃ and 60℃ provides sufficient heating to promote adhesion while avoiding damage to the label from high temperatures. Setting the second preset temperature range to a value between 40℃ and 60℃ provides sufficient softening while also avoiding damage to the label from high temperatures.

[0071] Figure 8 The diagram illustrates the steps of a method for recognizing label outlines. In one embodiment, as shown... Figure 8 As shown, after step 108, the automatic labeling method for medical injection molded parts further includes: Step 801: Collect the edge contour of the bottom of the medical injection molded part module from below.

[0072] Step 802: If some tabs protrude beyond the edge outline, generate the corresponding abnormal component information.

[0073] This embodiment detects the folding effect of the label. If part of the label protrudes beyond the edge contour, it indicates that the bent edge is not at the boundary between the adhesive and non-adhesive areas. Anomaly information needs to be generated to indicate poor adhesion between the medical injection molded module and the label. Furthermore, during label preparation, multiple small holes can be pre-drilled along the boundary between the adhesive and non-adhesive areas to help ensure more precise placement of the bent edge at the boundary in steps 107 and 108.

[0074] Figure 9 The diagram illustrates the steps of a classification method. In one embodiment, as shown... Figure 9 As shown, step 109 includes: Step 901: Classify medical injection molded parts modules with different module parameters based on machine vision.

[0075] Step 902: Move the medical injection molded parts modules of each category to the corresponding labeling and finishing station.

[0076] In this step, different module parameters correspond to different dimensional parameters. Machine vision can be used to classify medical injection molded parts modules with different module parameters. Then, each category is moved to the corresponding labeling and finishing station to complete the classification.

[0077] This application also provides an automatic labeling system for medical injection molded parts. In one embodiment, the system includes: a parameter configuration module, a tilt adjustment module, a pasting module, a bending module, and a completion module.

[0078] The parameter configuration module is configured to: identify the module parameters of the medical injection molded part module; the medical injection molded part module includes multiple injection molding units; control the label output machine to output labels with corresponding parameters according to the module parameters; the label includes an adhesive area and a non-adhesive area, and the output end of the label output machine is equipped with a transmission roller.

[0079] The tilt adjustment module is configured to: grasp the medical injection molded part module, move it above the application station, and switch to the set tilt angle.

[0080] The pasting module is connected to the parameter configuration module. The pasting module is configured to: align the edge of the pasting surface of the medical injection molded part module with the edge of the adhesive surface of the adhesive area and paste them together; move the medical injection molded part module diagonally downwards at a set tilt angle so that the pasting surface of the medical injection molded part module and the adhesive surface of the adhesive area gradually press together over the transmission roller; move the medical injection molded part module carrying the label to the first pressing surface of the pasting station and perform the pasting and pressing process for a first preset time.

[0081] The bending module is communicatively connected to the bonding module. The bending module is configured to: after a first preset time, move the medical injection molded part module toward the bending station. During the movement, the stop blocks the non-adhesive area, causing the non-adhesive area and the adhesive area to bend each other; move the medical injection molded part module to the second pressing surface of the bending station, and perform a bending and pressing process on the folded non-adhesive area and adhesive area for a second preset time.

[0082] The completion module and the bending module are connected. The completion module is configured to move the medical injection molded part module carrying the label to the labeling completion station.

[0083] This application identifies module parameters of medical injection molded parts, such as the arrangement and quantity of injection molding units through image parameters and preset models, and controls the label output machine to output labels with sizes and arrangements matching the application surface. By setting an inclination angle and moving downwards at an angle along the transmission rollers, the label is tightly and completely applied to the application surface, effectively avoiding air bubbles caused by loose application and improving application quality and automation accuracy.

[0084] During the application process, the adhesive area of ​​the label helps to secure the multiple injection units within the medical injection molding module, preventing them from separating during subsequent transportation. Combined with blocking and bending compression, the non-adhesive area of ​​the label is folded against the adhesive area. The entire medical injection molding module is transported as a single product. Upon arrival at the destination, when needed, the entire label can be easily peeled off from the non-adhesive area, conveniently separating the multiple injection units and balancing transportation stability with ease of use.
