[0003] Of course, it can be applied in the field of medical devices. Endoscopes are widely used in the medical field for diagnosing and treating pathological tissues in body cavities. When doctors use endoscopes, they need to be inserted into the natural cavity of the human body. Therefore, the outer wall of the insertion tube is required to be smooth and uniform, and the surface roughness and other requirements need to be strictly enforced to ensure that the insertion tube can freely enter and exit the natural cavity of the human body.

[0004] The current problems with endoscopes are: Since the insertion tube assembly is composed of multiple components, the outer layer of curved rubber, also known as snake bone skin, needs to be assembled with the insertion tube by bonding. The glue points are small, and the usual automated glue dispensing equipment is not easy to use. The current process uses manual glue dispensing and bonding, which results in uneven glue dispensing and different widths. Before the glue is cured, it is easy to concentrate on one side due to gravity, resulting in excessive ellipticity at the bonding point, which ultimately affects the smooth and free delivery of the endoscope insertion part into the human body cavity. Currently, it is necessary to manually adjust the position of the insertion part during the glue curing process to solve this problem. Utility Model Content

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] See also Figures 1 to 3 , Figure 2 The schematic diagram of the structure of the dispensing auxiliary device of the utility model includes a base 1, a driving member 2 mounted on the base 1, a support frame 3 and a dispensing mechanism, and the support frame 3 is used to support the dispensing mechanism and the driving member 2. The base 1 is a long strip structure with a flat top and supporting feet at the bottom for carrying other components. The driving member 2 is used to drive the dispensing mechanism to operate.

[0026] The glue dispensing mechanism includes a rotating shaft 4 and a clamping member 5. One end of the rotating shaft 4 is linked to the output shaft of the driving member 2, and the other end is detachably connected to the clamping member 5. The driving member 2 is used to drive the rotating shaft 4 to rotate, and the clamping member 5 is used to fix the insertion tube assembly 10. The insertion tube assembly 10 is a partial structure of the snake bone in this application and is a workpiece that needs glue dispensing. One end of the rotating shaft 4 is driven to rotate by the driving member 2, and the other end of the rotating shaft 4 is connected to the clamping member 5. The insertion tube assembly 10 is fixed on the clamping member 5, thereby driving the clamping member 5 and the insertion tube assembly 10 to rotate at a uniform speed. The glue dispensing tool is used to dip the glue close to the middle position of the insertion tube assembly 10 and the snake bone skin 20 for glue dispensing, so that the glue is evenly distributed on the specified cylindrical surface during rotation, thereby solving the problems of inconsistent product quality, low yield, and poor ellipticity of the insertion assembly during the production process.

[0027] The glue used in the above-mentioned dispensing process is provided by the outside, and the glue is used to bond the two material parts. The dispensing tool can be an acupuncture needle, which is used to transfer the glue to the bonding part. The needle tip length is 13mm and the diameter is 0.25mm. The dispensing part is the connection between the insertion tube assembly 10 and the snake bone skin 20.

[0028] In one embodiment, the above-mentioned glue dispensing auxiliary device is used for bonding the snake bone cover of the endoscope.

[0029] In the present application, the clamping member 5 includes an upper fixing block 51 and a lower fixing block 52. The upper fixing block 51 is provided with a first accommodating cavity, and the lower fixing block 52 is provided with a second accommodating cavity. The first accommodating cavity and the second accommodating cavity are arranged opposite to each other to form an accommodating space. The insertion tube assembly 10 is arranged in the accommodating space and is covered by the upper fixing block 51 and the lower fixing block 52. The upper fixing block 51 and the lower fixing block 52 can be in the shape of a semicircle, a rectangle or other polygon with a cavity, and the two can be buckled together, and the first accommodating cavity and the second accommodating cavity are combined into the accommodating space.

[0030] In the present application, the rotating shaft 4 is detachably connected to the lower fixed block 52 and is covered on the outer periphery of the lower fixed block 52. At the same time, the clamping member 5 in the present application also includes a cover 53, which is covered on the outer periphery of the upper fixed block 51 and is buckled with the rotating shaft 4. The above arrangement enables the cover 53 and the rotating shaft 4 to be respectively covered on the outside of the upper fixed block 51 and the lower fixed block 52 to form an external shell, which clamps the upper fixed block 51 and the lower fixed block 52 during use, and clamps the insertion tube assembly 10 installed in the accommodating space between the upper fixed block 51 and the lower fixed block 52. When the rotating shaft 4 rotates, it drives the clamping member 5 to rotate at the same time, and the clamping member 5 drives the insertion tube assembly 10 to be glued to rotate, so as to carry out the subsequent glue dispensing procedure.

[0031] In the present application, the driving member 2 includes a motor 21, a motor controller 22 and a synchronous wheel 23. The motor controller 22 is used to control the opening and closing of the motor 21. The output shaft of the motor 21 is connected to the synchronous wheel 23. The synchronous wheel 23 is connected to the rotating shaft 4 to drive the rotating shaft 4 to rotate.

[0032] In one embodiment, the number of synchronous wheels 23 in the present application is at least two, and the multiple synchronous wheels 23 are linked by a transmission belt 24. Since the motor 21 is arranged on one side of the rotating shaft 4, in order to avoid interference, a first synchronous wheel and a second synchronous wheel are arranged, and the first synchronous wheel and the second synchronous wheel are arranged in parallel, and the two are driven by the transmission belt 24. The first synchronous wheel is linked with the output shaft of the motor 21 to transmit power to the second synchronous wheel, and the second synchronous wheel is sleeved on the rotating shaft 4 to drive the rotating shaft 4 to rotate.

[0033] In the present application, there are multiple support frames 3, which are arranged in sequence along the length direction of the shaft 4, and the shaft 4 passes through the multiple support frames 3 in sequence to support the shaft 4. In one embodiment, there are two support frames 3, and the shaft 4 passes through them in sequence to carry the shaft 4.

[0034] The dispensing auxiliary device in the present application further includes a bearing 6, which is mounted on the support frame 3 and fixedly connected to the rotating shaft 4. When the rotating shaft 4 is driven to rotate by the motor 21, the bearing 6 rotates synchronously.

[0035] The dispensing auxiliary device in the present application also includes a support platform 7, which is fixed on the base 1, and the front end of the insertion tube assembly 10 is supported on the support platform 7. The insertion tube assembly 10 will be pulled forward during and after the dispensing process, so a vertical support platform 7 is set at the front end of the rotating shaft 4, and a structure with the same shape as the insertion tube assembly 10 is provided on the support platform 7. For example, when the insertion tube assembly 10 is cylindrical, a circular groove is set on the top surface of the support platform 7, so that the insertion tube assembly 10 can be placed in the groove to bear the weight of the front end of the insertion tube assembly 10, so that the front and back are balanced, and the glue can be evenly distributed on the specified cylindrical surface to avoid deviation in dispensing.

[0036] The dispensing auxiliary device in the present application also includes a support tube 8, which is sleeved on the end of the rotating shaft 4 away from the clamping member 5, that is, the rear end of the rotating shaft 4. The support tube 8 is used to support and protect the rear end of the insertion tube assembly 10, and at the same time form a weight balance for the two ends of the rotating shaft 4.

[0037] By using the dispensing auxiliary device of the utility model, the glue is evenly distributed on the specified cylindrical surface during the rotation process by relying on the effects of gravity and centrifugal force in a rotating manner, thereby solving the problems of inconsistent product quality, low yield, poor ovality of the insertion component, and unsmooth product feeding during the production process; solving the problem of low production efficiency, reducing labor costs, and improving production efficiency.
