Description

Technical Field

[0001] This utility model relates to the field of medical silicone parts processing technology, specifically a compression-type adhesion elimination mechanism for medical silicone parts. Background Technology

[0002] In the manufacturing process of medical silicone caps, a cross-shaped incision is typically machined at the top. This incision must achieve specific functions while maintaining dustproof and sealing properties, thus requiring high machining precision. However, due to the narrow gap of the incision, silicone material is prone to sticking together at the edges after cutting, affecting the normal opening and closing of the cap and its usability.

[0003] Currently, most processing quality inspections rely on vision inspection devices. While these devices can identify cut shapes and the presence of material adhesion, their function is limited to detection and judgment; they lack the ability to physically process identified material adhesion. Therefore, when silicone caps with adhesion defects are detected, manual or additional equipment is still required for subsequent processing, leading to inefficient process connections and impacting overall production efficiency and product quality consistency.

[0004] In summary, the existing technology lacks an integrated solution that can mechanically address material adhesion problems during or after testing.

[0005] Therefore, it is necessary to design a mechanical structure that combines detection and processing functions to automatically remove the silicone caps, thereby improving the automation level and product qualification rate of medical silicone cap production. Utility Model Content

[0028] To ensure the appearance quality of the product, a compression-type adhesion elimination mechanism was designed for medical silicone part A. The specific solution is as follows:

[0029] Example 1

[0030] like Figure 1-4 As shown, a compression-type adhesion elimination mechanism for medical silicone parts A includes a feeding assembly 1 and a guide assembly 2, a detection assembly 3, and a compression assembly 4 arranged sequentially along the feeding direction. The guide assembly 2 is provided with a guide plate 201, which allows the silicone parts A to be arranged in a straight line along the feeding direction. The detection assembly 3 is provided with a detection camera 303 for detecting the state of the silicone parts A. The compression assembly 4 is provided with symmetrical lateral conveyor belts 401, and the lateral conveyor belts 401 are connected to an adjustment mechanism for adjusting the spacing. Compression plates 402 are provided between the lateral conveyor belts 401 for compressing the silicone parts A.

[0031] The feeding assembly 1 includes a belt conveyor and a drive motor. Specifically, the drive motor is located at the discharge end of the belt conveyor in the discharge direction.

[0032] The upper part of the extrusion plate 402 is provided with a waist-shaped hole for adjusting the height. According to the size specifications of the silicone part A, the height of the extrusion plate 402 can be adjusted to make it suitable for extruding silicone parts A of various specifications. When the silicone part A moves to pass under the extrusion plate 402, the top of the silicone part A is machined with a slit. The extrusion of the extrusion plate 402 can apply force to the slit and break any adhesion that may exist at the slit.

[0033] The extrusion plate 402 is adjustablely installed on the inner side of the side conveyor belt 401. The two ends of the extrusion plate 402 adopt an arc transition design, which allows the silicone part A to move smoothly without damaging the product surface.

[0034] Each end of the side conveyor belt 401 is equipped with a servo drive motor 4011, and the servo drive motor 4011 operates in conjunction with the side conveyor belt. The side conveyor belt 401 and the feeding conveyor belt run at the same speed, which can ensure that the silicone part A will not fall over due to speed difference during the conveying process.

[0035] The adjustment mechanism includes a mounting frame 403, a lead screw 404, a handwheel 405, and a slider. The slider is slidably connected to the lead screw 404 and fixedly connected to a side conveyor belt 401 on one side. The two ends of the lead screw 404 are screwed to the two ends of the mounting frame 403, and one end of the lead screw 404 is fixedly connected to the handwheel 405.

[0036] A first air-blowing component is provided between the guide component 2 and the detection component 3 to thin out the conveyor queue. When the silicone parts A are conveyed on the feeding conveyor belt, they are arranged in a straight line, but not in an intermittent arrangement. If the arrangement is too dense, it will easily affect the subsequent visual inspection. Therefore, the first air-blowing component can blow air intermittently to thin out the silicone parts A that are arranged too densely, thus ensuring the accuracy of the subsequent inspection.

[0037] A second air-blowing component is provided between the detection component 3 and the extrusion component 4 to remove products that have fallen over. The silicone parts A are conveyed on the feeding conveyor belt, but they are not always upright and may fall over. Therefore, when the detection component 3 detects and determines that a product has fallen over, the second air-blowing component can remove it from the feeding conveyor belt, ensuring that all silicone parts A entering the extrusion component 4 are upright and that the extrusion plate 402 can extrude the cut of the silicone part A.

[0038] The mounting positions of the lead screw 404 and handwheel 405 are equipped with locking clamps 406 to maintain the position of the side conveyor belt 401 and prevent slippage. For silicone parts A of different specifications, the operator can use the forward / reverse handwheel 405 to slide the slider, thereby adjusting the spacing between the side conveyor belts 401 to match the specifications of the silicone parts A, so that the side conveyor belt 401 can clamp the silicone parts A for conveying.

[0039] The guide assembly 2 includes a mounting plate 202, a guide plate 201, and a side pressure block 203. The inner side of the mounting plate 202 has the same curvature as the guide plate 201, and the lower part of the inner side of the mounting plate 202 is provided with multiple air vents 2021 for blowing the silicone part A. The guide plate 201 is provided with a clearance opening, and the side pressure block 203 is installed in the clearance opening for applying slight side pressure to the side of the silicone part A. When the silicone part A is conveyed on the feeding conveyor belt, several silicone parts A can be gathered together at the same time. The air vents 2021 at the lower part of the mounting plate 202 can blow the silicone part A, causing it to move towards one side of the feeding conveyor belt. When the silicone part A contacts the guide plate 201, it can also move towards one side of the feeding conveyor belt. The side pressure block 203 can apply slight side pressure to the side of the silicone part A when it passes by, and at the same time, it can act as a block, causing excess silicone parts A to move backward, so that the silicone parts A are arranged one by one.

[0040] The detection component 3 includes a base 301, a column 302, and a detection camera 303. The base 301 is fixedly installed on one side of the feeding conveyor belt, the column 302 is fixed on the base 301, and the detection camera 303 is adjustablely installed on the side of the column 302. The detection camera 303 faces the conveying path of the silicone part A. The silicone part A passes under the detection camera 303. The detection camera 303 detects whether the silicone part A is on the front or the back. If the silicone part A is on the back, it will be rejected when it moves to the second air blowing component, so that it can re-enter the feeding process.

[0041] The extrusion-type adhesion elimination mechanism in this solution integrates multiple functions such as feeding, guiding, detection, rejection, and extrusion. It automates the process of feeding silicone parts A from disordered to ordered arrangement, state screening, and extrusion treatment, reducing manual intervention, improving production efficiency, ensuring consistency in the processing, and meeting the high requirements of modern medical device production.

[0042] The airflow through the air outlet 2021 of the guide plate 201 and the mounting plate 202, as well as the fine-tuning and blocking effect of the side pressure block 203, enable the silicone parts A to be quickly arranged in a straight line.

[0043] Before inspection, the overly dense queues are thinned out to ensure that each silicone part A can be clearly captured by the inspection camera 303.

[0044] The detection camera 303 determines the front and back status of the silicone part A in real time, and the subsequent air blowing component automatically removes the fallen products, ensuring that only the silicone part A placed upright with the cut facing up can enter the extrusion assembly 4, thereby ensuring the effective operation of the extrusion sheet 402.

[0045] The extrusion plate 402 is equipped with an adjustable height, which can apply controllable force to the cut of the silicone part A, and can eliminate the adhesion of the cut. The arc transition design at both ends of the extrusion plate 402 ensures a smooth force application process and avoids damage to the product surface.

[0046] The adjustment mechanism consisting of lead screw 404, handwheel 405, and slider can stably adjust the spacing of the side conveyor belt 401 to adapt to silicone parts A of different widths and achieve stable clamping and conveying. The locking clamp 406 ensures that the side conveyor belt 401 is stable after adjustment.

[0047] Example 2

[0048] In this embodiment, the structure of the mechanism is basically the same as that of Embodiment 1. The difference is that the upper part of the extrusion plate 402 adopts a sliding structure with a dovetail groove and a dovetail slider. The upper end of the slide rail is provided with a knob-type micrometer and a locking clamp 406, which can quickly and accurately adjust the position and height of the extrusion plate 402 and keep it fixed.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
