Description

Technical Field

[0001] The present invention relates to a finger sleeve expansion device and its expansion process, belonging to the field of automated production equipment. Background Art

[0002] Cold shrinkable cable accessories are made by injection molding elastomeric materials in the factory, and then expanded in diameter and lined with plastic spiral supports to form various components of cable accessories. Cold shrinkable finger sleeves are common cold shrinkable cables. Before use, they generally need to be expanded, and then pre-installed in a pre-stretched state. After the pre-installation is completed, the support core is removed, causing the finger tips to shrink onto the pre-set inner core. The function of this type of cable accessory is to create a sealed environment for individual cable branches and the entire cable sheath, playing the roles of insulation and moisture-proof sealing.

[0003] In the traditional finger sleeve expansion process, the operation usually starts with the expansion of the thumb part. Generally, the thumb part is first placed in a dedicated expansion device, and by gradually applying pressure, the material is gradually expanded to the required size. After the expansion of the thumb part is completed, the operator needs to replace another set of equipment to perform a similar expansion process on the little finger part. This process mainly relies on manual or semi-automatic equipment to complete. Using this method for expansion requires a relatively high level of manpower on the one hand. On the other hand, due to the limitations of the equipment and manual operations, the sizes of the expanded products often have obvious deviations, making it difficult to ensure product consistency. During the expansion process, product failures often increase due to the adhesion of plastic debris generated by the supports, and how to clean impurities is also an important issue in the production process. Summary of the Invention

[0004] In order to solve the problems in the above-mentioned background art, the present invention provides a finger sleeve expansion device and its expansion process.

[0005] The technical solution for achieving the purpose of the present invention is: a finger sleeve expansion device, including a bottom plate, a little finger expansion component, a thumb expansion component, a driving component, a sample slot, and a stacking slot.

[0006] The little finger expansion component and the thumb expansion component are respectively arranged on the bottom plate and the relative sliding distance in the horizontal direction is controlled by the driving component. The sample slot is arranged between the little finger expansion component and the thumb expansion component. During use, the sample is placed in the sample slot.

[0007] The little finger expansion component and the thumb expansion component respectively include branchable little finger expansion fingers and thumb expansion fingers for expansion. The little finger expansion fingers and the thumb expansion fingers are arranged opposite to each other, and their midlines are flush with the midline of the sample finger sleeve in the sample slot.

[0008] The stacking slot is divided into a thumb support tube stacking slot and a little finger support tube stacking slot, which are used to store thumb expansion tubes and little finger expansion tubes.

[0009] The little finger expansion finger and the thumb expansion finger are controlled by a driving component to be in an expanded state.

[0010] By adopting the above-mentioned finger sleeve expansion device, the same set of equipment can be used for the expansion of the thumb and the little finger, and the expansion process of the little finger can be carried out synchronously. Compared with the step-by-step expansion scheme, the expansion steps are more stable and accurate, which can effectively ensure the accuracy and safety during the operation. This device can greatly improve the work efficiency and ensure the consistency and precision of the products.

[0011] Further or optionally, the little finger expansion component further includes a little finger expansion base, a little finger expansion base guide rail and a first driving component. The first driving component includes a little finger expansion base forward pushing cylinder, a little finger expansion support tube forward pushing cylinder and a little finger expansion cylinder;

[0012] The little finger expansion base is pushed by the little finger expansion base forward pushing cylinder and is slidably connected to the bottom plate along the little finger expansion base guide rail;

[0013] A little finger expansion tube support tube window is arranged on the little finger expansion base. The lower end of the little finger support tube stacking groove is connected to the little finger expansion tube support tube window, and a forward pushing fixture for the little finger is arranged at the front end of the little finger expansion support tube forward pushing cylinder;

[0014] The opening and closing degree of the little finger expansion finger is controlled by the little finger expansion cylinder.

[0015] By adopting the little finger expansion component with the above structure, the accurate horizontal displacement of the little finger expansion base can be realized, and the opening state of the little finger expansion finger can be accurately controlled according to the expanded state. The distance between the little finger expansion component and the thumb expansion component and the expansion range of the little finger expansion finger can be flexibly controlled according to the finger sleeve specifications to ensure the accuracy of the expansion.

[0016] The thumb expansion component further includes a thumb expansion base and a second pushing component. The second pushing component includes a thumb expansion cylinder and a thumb expansion support tube forward pushing cylinder;

[0017] A thumb support tube is placed in the thumb support tube stacking groove;

[0018] The output shaft of the thumb expansion support tube forward pushing cylinder is arranged parallel to the bottom plate. A thumb expansion tube support tube window is arranged on the thumb expansion base, and a forward pushing fixture for the thumb matching with the thumb support tube is arranged at one end of the thumb expansion support tube forward pushing cylinder;

[0019] The opening and closing degree of the thumb expansion finger is controlled by the thumb expansion cylinder.

[0020] During assembly, place the thumb expansion tube and the little finger expansion tube into the thumb support tube stacking trough and the little finger support tube stacking trough respectively, so that the outer wall is parallel to the axial center line of the thumb expansion finger and the little finger expansion finger, and the height of the slot below the thumb support tube stacking trough and the little finger support tube stacking trough is designed to be an adjustable structure. The distance between the slot and the axial center line of the thumb expansion finger and the little finger expansion finger is set according to the specifications of the finger sleeve to adapt to the diameter requirements of the expansion finger.

[0021] The above-mentioned forward pushing fixture for the thumb is selected according to the specifications of the finger sleeve. The edge of the fixture has a groove for the thumb expansion tube. During the forward pushing process, the tube body of the thumb expansion tube is placed into the groove, and the internal raised part is inserted into the thumb expansion tube. This structure ensures that the thumb expansion tube is better centered during the finger sleeve expansion process, thereby improving the accuracy of the expansion process.

[0022] The push-forward fixture for the little finger may also adopt a structure similar to that of the push-forward fixture for the thumb.

[0023] Further or optionally, the thumb expansion finger is wavy in shape, with a hollow structure inside, and an air hole is provided on one side close to the inner wall of the finger sleeve, and the air hole is connected to the vacuum system.

[0024] The inside of the thumb adopts a hollow structure, which can adsorb the finger sleeve during the docking process with the little finger expansion finger after the thumb expansion process is completed, to prevent accidental slippage during the pushing process and affect the subsequent processes. The air hole structure can be subjected to a vacuum treatment step, and can also be subjected to an air blowing treatment. In the removal step after the thumb support tube is installed, an air film is formed between the thumb expansion finger and the thumb support tube, so that there is no direct contact between the thumb expansion finger and the thumb support tube during the removal process, reducing the relative friction between the two, thereby reducing the possibility of the thumb support tube sliding during the withdrawal of the thumb expansion finger, and improving the stability of product performance.

[0025] The present application also provides a finger sleeve expansion process, which specifically includes the following steps:

[0026] Synchronous expansion;

[0027] Inspection;

[0028] Remove impurities;

[0029] Encapsulation.

[0030] The expansion process is carried out based on the above-mentioned expansion device. During the expansion process, multiple little fingers in the same direction are expanded synchronously. The overall expansion efficiency is high and the stability is good. After completing the expansion step, the workpiece specifications can be checked, cleaned, impurities removed and packaged, ensuring the accuracy and stability of the finger sleeve expansion process. The product has good consistency and high surface cleanliness, and has better performance than similar products on the market.

[0031] Further or optionally, the expansion step includes the following steps:

[0032] Place the thumb expansion tube and the little finger expansion tube into the thumb support tube stacking groove and the little finger support tube stacking groove respectively;

[0033] Place the finger cot in the sample groove, with the thumb and little finger directions of the finger cot corresponding to the directions of the little finger expansion finger and the thumb expansion finger;

[0034] Put the thumb support tube onto the thumb expansion finger to expand the thumb;

[0035] Move the little finger expansion finger forward and stop when it reaches the preset position, then insert the little finger expansion finger into the little finger of the finger cot;

[0036] After confirming that the expansion fingers of the thumb and little finger are in place, expand the three finger cots step by step synchronously;

[0037] Insert the thumb support tube into the thumb and the little finger support tube into the little finger, and then withdraw the little finger expansion finger and the thumb expansion finger.

[0038] During the operation, the expansion speed of the finger cot can be adjusted by controlling the opening and closing speeds of the thumb expansion finger and the little finger expansion finger, and the specific speed is selected according to the material parameters of the finger cot.

[0039] Further, for the structures of the little finger expansion finger and the thumb expansion finger, after the thumb expansion finger completes the expansion, it enters the vacuum pumping mode; before the thumb expansion finger is withdrawn, it first enters the blowing mode and then is withdrawn.

[0040] During the operation, the vacuum degree of vacuum pumping and the blowing intensity of the blowing mode are selected according to the material of the finger cot, and it is necessary to avoid deformation of the outer surface of the finger cot caused by excessive vacuum pumping or excessive blowing.

[0041] The inspection step uses a laser dimension detector to test the dimensions and the surface flatness of the product. The above-mentioned laser dimension detection device can be a commercially available product. Just perform a modeling process on the product before use and confirm its specification parameters.

[0042] The impurity removal step includes several steps of pretreatment feeding, water spraying, and air-blowing drying, where

[0043] Pretreatment feeding: Products meeting the set standards first enter the water spraying area through a conveyor belt or other transmission equipment;

[0044] Water spraying: The products are sprayed from multiple angles by high-pressure nozzles in the water spraying area to effectively remove the attached dust, dirt, and other loose impurities;

[0045] Air-blowing drying: The wet products after water spraying enter the air-blowing area, and the strong air flow generated by a blower is used to quickly dry the moisture on the surface of the products.

[0046] A water spray device can be used during the water spray process, a direct blowing device can be used during the air drying process, or the product that has been treated with water spray can be stirred while being blown.

[0047] The water shower step also includes water recovery and filtration processes;

[0048] The blast drying step also includes an exhaust gas treatment process.

[0049] The water recovery machine filtration process is equipped with a wastewater recovery box. In the waste gas treatment process, a purification device needs to be set up according to the waste gas composition to prevent wastewater and waste gas from polluting the workshop environment.

[0050] By adopting the above technical solution, the present invention has the following beneficial effects:

[0051] (1) The finger sleeve expansion device of the present application can use the same set of equipment to expand the thumb and the little finger, and the expansion process of the little finger can be carried out simultaneously. Compared with the step-by-step expansion scheme, the expansion steps are more stable and accurate, which can effectively ensure the accuracy and safety of the operation process. The device can greatly improve work efficiency and ensure the consistency and accuracy of the product.

[0052] (2) A finger sleeve expansion device of the present application can realize precise horizontal displacement of the little finger expansion base and accurately control the expansion state of the little finger expansion finger according to the expansion state. The distance between the little finger expansion component and the thumb expansion component and the expansion range of the little finger expansion finger can be flexibly controlled according to the specifications of the finger sleeve to ensure the accuracy of the expansion.

[0053] (3) A thumb expansion support tube forward push cylinder of a finger sleeve expansion device of the present application is provided at one end with a thumb forward push fixture that matches the thumb support tube. The distance between the slot and the axial center line of the thumb expansion finger and the little finger expansion finger can be set according to the finger sleeve specifications to adapt to the diameter requirements of the expansion finger.

[0054] (4) A hollow structure is adopted inside the thumb expansion finger of a finger sleeve expansion device of the present application, so that the finger sleeve can be adsorbed during the process of docking with the little finger expansion finger after completing the thumb expansion process, so as to prevent accidental slippage during the pushing process and affect the subsequent process. Its air hole structure can be subjected to a vacuum treatment step, and can also be subjected to an air blowing treatment. In the removal step after the thumb support tube is loaded, an air film is formed between the thumb expansion finger and the thumb support tube, so that there is no direct contact between the thumb expansion finger and the thumb support tube during the removal process, thereby reducing the relative friction between the two, thereby reducing the possibility of the thumb support tube sliding during the withdrawal process of the thumb expansion finger, and improving the stability of product performance.

[0055] (5) This application also provides a finger cot expansion process, in which multiple little fingers in the same direction are synchronously expanded during the expansion process. The overall expansion efficiency is high and the stability is good. After the expansion step is completed, workpiece specification inspection, cleaning and impurity removal, and encapsulation work can be carried out, ensuring the accuracy and stability of the finger cot expansion process. The product has good consistency and high surface cleanliness, and has better performance compared with similar products in the market.

[0056] (6) In a finger cot expansion process of this application, a step-by-step expansion step is adopted. In the expansion step, the expansion speed of the finger cot can be adjusted by controlling the opening and closing speeds of the thumb expansion finger and the little finger expansion finger. The specific speed is selected according to the material parameters of the finger cot.

[0057] (7) In a finger cot expansion process of this application, vacuum pumping or blowing can be carried out as needed during the expansion process. After pressure adjustment according to the finger cot material, it can effectively avoid the deformation of the outer surface of the finger cot caused by excessive vacuum pumping or excessive blowing.

[0059] (9) A finger cot expansion process of this application is provided with several steps of pretreatment feeding, water spraying, and air-blowing drying, which can effectively ensure the surface cleanliness of the product and prevent product contamination from affecting the use effect.

[0060] (10) In the water spraying and air-blowing drying steps of a finger cot expansion process of this application, a wastewater treatment tank and an exhaust gas treatment device are set, which can avoid pollution to the production environment during the sample treatment process.

[0075] (Embodiment 1)

[0076] See Figure 1 , a finger sleeve expansion device, including a bottom plate 1, a little finger expansion assembly 2, a thumb expansion assembly 3, a drive assembly 4, a sample slot 4, and a stacking slot 5.

[0077] The little finger expansion assembly 2 and the thumb expansion assembly 3 are respectively arranged on the bottom plate 1 and the relative sliding distance in the horizontal direction is controlled by the drive assembly 4. The sample slot 4 is arranged between the little finger expansion assembly 2 and the thumb expansion assembly 3. During use, the sample is placed in the sample slot 4.

[0078] The little finger expansion assembly 2 and the thumb expansion assembly 3 respectively include branchable little finger expansion fingers 21 and thumb expansion fingers 31 for expansion. The little finger expansion fingers 21 and the thumb expansion fingers 31 are arranged opposite to each other, and the midlines are flush with the midline of the sample finger sleeve in the sample slot 4.

[0079] The stacking slot 5 is divided into a thumb support tube stacking slot 51 and a little finger support tube stacking slot 52 for storing the thumb expansion tube and the little finger expansion tube.

[0080] The expansion states of the little finger expansion fingers 21 and the thumb expansion fingers 31 are controlled by the drive assembly 4.

[0081] During the production process, the numbers of the little finger expansion fingers 21 and the thumb expansion fingers 31 are set according to the finger sleeve parameters first.

[0082] In the working state, the finger sleeve is placed in the sample slot 4, and the finger sleeve in the sample slot 4 is flush with the midline of the thumb expansion fingers 31 of the thumb expansion assembly 3. During use, the thumb expansion fingers 31 are inserted into the thumb part of the finger sleeve, and the thumb expansion fingers expand the thumb part of the finger sleeve. After the expansion is completed, the thumb expansion tube is placed into the expanded thumb, and then the thumb expansion fingers 31 are withdrawn.

[0083] After the expansion of the thumb part of the finger cot is completed, push the little finger expansion finger 21 forward, insert it into the corresponding little finger of the finger cot, and then expand the little finger of the finger cot. During the expansion process, it is necessary to pay attention to the synchronous operation among the little fingers to avoid specification differences caused by asynchronous operation during the expansion of the finger cot.

[0084] As an extended solution of the present application scheme, the little finger expansion assembly 2 and the thumb expansion assembly 3 are driven by a driving assembly, and the driving cylinder performs telescopic operation.

[0085] Specifically, the little finger expansion assembly 2 further includes a little finger expansion base 22, a little finger expansion base guide rail 23 and a first driving assembly 24. The first driving assembly 24 includes a little finger expansion base forward push cylinder 241, a little finger expansion support tube forward push cylinder 242 and a little finger expansion cylinder 243;

[0086] The little finger expansion base 22 is pushed by the little finger expansion base forward push cylinder 241 and is slidably connected to the bottom plate 1 along the little finger expansion base guide rail 23;

[0087] A little finger expansion tube support tube window 221 is provided on the little finger expansion base 22. The lower end of the little finger support tube stacking groove 52 is connected to the little finger expansion tube support tube window 221, and a forward push fixture for the little finger is provided at the front end of the little finger expansion support tube forward push cylinder 231;

[0088] The opening and closing degree of the little finger expansion finger 21 is controlled by the little finger expansion cylinder 243.

[0089] In the above structure, the requirement for the length specification of the finger cot is met by the little finger expansion base forward push cylinder 241, and the positional relationship between the little finger expansion finger 21 and the finger cot during the expansion of the finger cot is controlled by the little finger expansion support tube forward push cylinder 231. This structure can achieve secondary adjustment of the distance between the little finger expansion finger 21 and the finger cot, making the adjustment more accurate.

[0090] A pressure sensing device can also be provided at the lower part of the above little finger expansion finger 21 and thumb expansion finger 31. When the little finger expansion finger 21 and the thumb expansion finger 31 are in actual contact with the finger cot bracket, the little finger expansion finger 21 and the thumb expansion finger 31 stop advancing and then enter the expansion process.

[0091] The thumb expansion assembly 3 further includes a thumb expansion base 32 and a second pushing assembly 33. The second pushing assembly 33 includes a thumb expansion cylinder 331 and a thumb expansion support tube forward push cylinder 332;

[0092] Thumb support tubes are placed in the thumb support tube stacking groove 51;

[0093] The output shaft of the thumb expansion support tube forward push cylinder 332 is arranged parallel to the bottom plate 1. A thumb expansion tube support tube window 321 is provided on the thumb expansion base 32. One end of the thumb expansion support tube forward push cylinder 332 is provided with a forward push fixture for the thumb that is matched with the thumb support tube.

[0094] The opening and closing degree of the thumb expansion finger 31 is controlled by the thumb expansion cylinder 331.

[0095] In the above structure, a bracket is provided below the thumb expansion support tube forward push cylinder 332, and the height of the bracket can be adjusted to prevent the thumb expansion support tube forward push cylinder 332 from bending or deforming.

[0096] The thumb expansion finger 31 is wavy and has a hollow structure inside. Air holes 311 are provided on one side close to the inner wall of the finger sleeve, and the air holes 311 are connected to a vacuum pumping system.

[0097] In the above structure, the air holes 311 are connected to a vacuum pumping device. During the expansion of the thumb of the finger sleeve, the vacuum pumping device does not work. After the thumb part is expanded, the vacuum pumping device enters the vacuum pumping state. At this time, the finger sleeve is pushed forward, and the negative pressure between the finger sleeve and the thumb expansion finger 31 can ensure that there is no sliding between them. In this state, the little finger of the finger sleeve is docked with the little finger expansion finger 21, and then the little finger expansion finger 21 is slowly opened. After the expansion is completed, the little finger expansion finger 21 is withdrawn.

[0098] Before the little finger expansion finger 21 and the thumb expansion finger 31 are completely withdrawn, the thumb expansion tube and the little finger expansion tube need to be placed into the finger sleeve. In the above structure, except that the thumb expansion finger 31 is set to be wavy, the little finger expansion finger 21 can also adopt the same structure.

[0099] After the thumb expansion tube and the little finger expansion tube are expanded, they extend into the finger sleeve from the polygonal structure formed by the branches of the little finger expansion finger 21 and the thumb expansion finger 31.

[0100] After the installation of the thumb expansion tube and the little finger expansion tube is completed, the little finger expansion finger 21 and the thumb expansion finger 31 need to be withdrawn. During this process, in order to reduce the friction between the little finger expansion finger 21 and the thumb expansion finger 31 and the little finger expansion tubes, thumb expansion tubes and finger sleeve on both sides, an air film needs to be formed between the layers. In addition to reducing friction and improving the withdrawal efficiency of the little finger expansion finger 21 and the thumb expansion finger 31, the air film can also reduce the friction between the finger sleeve itself, the little finger expansion tubes and the thumb expansion tubes, and avoid scratching the inner wall of the finger sleeve product and causing product defects.

[0101] This application also provides a process based on the above finger sleeve expansion device, including the following steps:

[0102] Synchronous expansion;

[0103] Inspection;

[0104] Impurity removal;

[0105] Encapsulation.

[0106] The above synchronous expansion process is carried out by the aforementioned expansion device, and the subsequent inspection, impurity removal and encapsulation processes are adjusted according to the actual production process.

[0107] Specifically, the expansion step includes the following steps:

[0108] Put the thumb expansion tube and the little finger expansion tube into the thumb support tube stacking groove 51 and the little finger support tube stacking groove 52 respectively;

[0109] Place the finger cot in the sample groove 4, and the thumb and little finger directions of the finger cot correspond to the directions of the little finger expansion finger 21 and the thumb expansion finger 31;

[0110] Put the thumb support tube on the thumb expansion finger 31 to expand the thumb;

[0111] Move the little finger expansion finger forward and stop when it reaches the preset position, then insert the little finger expansion finger 21 into the little finger of the finger cot;

[0112] After confirming that the expansion fingers of the thumb and the little finger are in place, synchronously expand the three finger cots step by step;

[0113] Push the thumb support tube into the thumb and the little finger support tube into the little finger, and then withdraw the little finger expansion finger 21 and the thumb expansion finger 31.

[0114] For the structures of the above little finger expansion finger 21 and thumb expansion finger 31, after the thumb expansion finger 31 completes the expansion, it enters the vacuum pumping mode; before the thumb expansion finger 31 is withdrawn, it first enters the blowing mode and then is withdrawn.

[0115] The inspection step uses a laser dimensional detector to test the size and the surface flatness of the product.

[0116] The specific inspection process can be carried out by visual observation or by using an intelligent testing device such as a laser detector, which is specifically arranged according to needs.

[0117] The impurity removal step includes several steps of pretreatment feeding, water spraying and air-blowing drying, where

[0118] Pretreatment feeding: Products meeting the set standards first enter the water spraying area through a conveyor belt or other transmission equipment;

[0119] Water spraying: The products are sprayed from multiple angles by high-pressure nozzles in the water spraying area to effectively remove the attached dust, dirt and other loose impurities;

[0120] Blowing drying: The wet product after water spraying enters the blowing area, and the strong air flow generated by the blower is used to quickly dry the moisture on the surface of the product.

[0121] To avoid environmental pollution problems caused during the production process, the water spraying step also includes a water recovery and filtration process; the blowing drying step also includes an exhaust gas treatment process.

[0122] The specific embodiments described above further elaborate on the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
