Description

Technical Field

[0001] This application belongs to the technical field of heat shrink tool holder cleaning, specifically relating to an automatic cleaning and detection device and cleaning and detection method for heat shrink tool holders. Background Technology

[0002] Heat shrink tool holders are heat-fitting systems that use the difference in thermal expansion coefficients between the tool holder and the tool to clamp the tool with power and high precision. Heat shrink tool holders are generally made of special stainless steel materials with a high thermal expansion coefficient, which enables heat fitting at a low temperature of 300°C. They can handle all machining processes from high-speed finishing to heavy cutting, such as milling, drilling, and reaming.

[0003] Before the heat shrink tool holder leaves the factory or after a period of use, the clamping force of the heat shrink tool holder needs to be tested to ensure safe clamping of the tool and stable operation. Before testing the clamping force of the heat shrink tool holder, the tool holder hole needs to be cleaned to avoid the influence of dust adhering to the hole wall on the test results.

[0004] Currently, manual cleaning of the tool holder hole is usually done by using a brush. This results in high labor costs and low cleaning efficiency, which increases the inspection cost of heat shrink tool holders and makes it easy to have incomplete cleaning, thus affecting the cleaning effect of heat shrink tool holders. Summary of the Invention

[0005] This application provides an automatic cleaning and inspection device for heat shrink tool holders, which reduces the inspection cost of heat shrink tool holders and improves the cleaning effect of heat shrink tool holders.

[0006] The technical solution adopted in this application is as follows:

[0007] An automatic cleaning and detection device for heat shrink tool holders includes:

[0008] A cleaning assembly, comprising a drive member and a cleaning rod connected to the drive member, the drive member being used to drive the cleaning rod to rotate, and the cleaning rod being provided with a cleaning part for cleaning the blade handle hole;

[0009] An air supply channel has an air inlet and an air outlet communicating with the air inlet, and the air outlet is disposed opposite to the cleaning rod;

[0010] A movable component, comprising a movable base and a power component, wherein the movable base is provided with a mounting position for mounting a heat-shrink knife handle, the mounting position being located between the air outlet and the cleaning rod, and the power component being used to drive the movable base to move between the cleaning component and the air supply channel.

[0011] By adopting the above technical solution, before using the automatic cleaning device for heat-shrinkable knife handles in this application, the air supply pipe of the external air supply equipment is connected to the air inlet of the air supply channel so that the external air supply equipment can deliver high-pressure gas into the air supply channel.

[0012] When cleaning the heat shrink handle, first install the heat shrink handle in the mounting position, then activate the power unit and drive unit. The power unit drives the moving base, which in turn moves the heat shrink handle towards the cleaning assembly. The drive unit drives the cleaning rod to rotate. As the moving base continues to move towards the cleaning assembly, the cleaning rod gradually extends into the handle hole of the heat shrink handle, allowing the cleaning part on the cleaning rod to clean the hole wall. The cleaning rod is set to clean the handle hole. After a period of time, the power unit drives the moving seat in the reverse direction, which in turn causes the moving seat to move the heat shrink tool holder toward the direction of the air supply channel. When the heat shrink tool holder moves to the air outlet, the high-pressure gas in the air supply channel enters the tool holder hole through the air outlet, so as to use the high-pressure gas to blow the hole wall of the tool holder hole. Thus, the combination of the cleaning part and the high-pressure gas achieves a thorough cleaning of the tool holder hole, thereby improving the cleaning effect of the heat shrink tool holder and ensuring the accuracy of the test results when the clamping force of the heat shrink tool holder is tested.

[0013] In addition, compared with the manual cleaning of heat shrink tool holders, the technical solution in this application realizes the automatic cleaning of tool holder holes, reduces the labor cost invested in cleaning tool holder holes and improves the cleaning efficiency of tool holder holes, thereby reducing the cleaning cost of tool holder holes and thus reducing the inspection cost of heat shrink tool holders.

[0014] Optionally, the movable seat has a support plate located between the cleaning rod and the air outlet, the support plate having a through hole for the cleaning part to pass through, and the support plate having a clamping structure located on the side of the through hole for applying pressure to the heat shrink handle.

[0015] By adopting the above technical solution, when installing the heat shrink tool holder, the heat shrink tool holder is first placed on the support plate, and the tool holder hole and the through hole of the heat shrink tool holder are in a coaxial state. Then, the clamping structure is used to apply pressure to the heat shrink tool holder to increase the stability of the heat shrink tool holder. This avoids the heat shrink tool holder from rotating with the cleaning part or moving under the action of high pressure gas during the cleaning of the tool holder hole, thus ensuring the cleaning effect of the heat shrink tool holder. On the other hand, it increases the safety of the tool holder hole cleaning process.

[0016] Because the support plate is provided with a through hole for the cleaning part to pass through, the cleaning part can be extended into the tool holder hole through the through hole, so as to ensure that the cleaning part can pass through the support plate and enter the tool holder hole.

[0017] Optionally, the clamping structure includes a rotary cylinder, the piston rod of which has a downward pressing arm that can contact the end face of the cylindrical portion of the heat shrink handle opposite to the support plate.

[0018] By adopting the above technical solution, after the heat shrink tool holder is placed on the support plate, the piston rod of the corner cylinder rotates, causing the piston rod to drive the lower pressure arm to rotate. This causes at least a portion of the lower pressure arm to be positioned opposite the cylindrical portion of the heat shrink tool holder. Then, the piston rod of the corner cylinder drives the lower pressure arm to move towards the cylindrical portion of the heat shrink tool holder, ultimately causing the lower pressure arm to contact the end face of the cylindrical portion of the heat shrink tool holder away from the support plate. At the same time, under the action of the piston rod, the lower pressure arm applies pressure to the cylindrical portion of the heat shrink tool holder towards the side where the support plate is located, thereby achieving the fixation of the heat shrink tool holder.

[0019] By setting the clamping structure as a rotary cylinder, the clamping structure is simplified, the cost of the clamping structure is reduced, and the production and manufacturing cost of the automatic cleaning and detection device for heat shrink tool holders is reduced.

[0020] Optionally, the support plate is provided with a support body, the support body having a receiving hole coaxially arranged with the through hole, and at least a portion of the heat shrink shank can extend into the receiving hole, so that the support body constitutes the mounting position.

[0021] By adopting the above technical solution, when the heat shrink tool holder is placed in the installation position, the heat shrink tool holder is aligned with the receiving hole, and then pressure is applied to the side of the heat shrink tool holder facing the receiving hole, so that at least a part of the heat shrink tool holder extends into the receiving hole. Since the receiving hole and the through hole are coaxially arranged, after at least a part of the heat shrink tool holder is extended into the receiving hole, the tool holder hole of the heat shrink tool holder is automatically coaxial with the through hole, so as to realize the positioning of the heat shrink tool holder by using the receiving hole, thereby reducing the installation difficulty of the heat shrink tool holder and further improving the cleaning efficiency of the tool holder hole.

[0022] Optionally, the automatic cleaning and detection device for heat-shrinkable knife handles further includes a detection rod that can extend into the knife handle hole. The detection rod is coaxially arranged with the cleaning rod, and the detection rod has a central hole. The end of the central hole near the cleaning rod forms the air outlet.

[0023] By adopting the above technical solution, since the detection rod can be inserted into the tool handle hole, and the end of the central hole near the cleaning rod forms an air outlet, the air outlet can be inserted into the inside of the tool handle hole to improve the cleaning effect of the high-pressure gas discharged through the air outlet on the tool handle hole, thereby further improving the accuracy of the detection results when detecting the clamping force of the heat shrink tool handle.

[0024] Optionally, a pressure sensor is provided at the end of the detection rod away from the cleaning rod, and the pressure sensor can detect the pressure on the detection rod.

[0025] By adopting the above technical solution, after the heat shrink handle moves to the position of the detection rod under the drive of the moving seat, the power component continues to drive the moving seat, so that the moving seat continues to drive the heat shrink handle in the direction away from the cleaning rod. This causes the detection rod to gradually extend into the handle hole. Due to the friction between the detection rod and the hole wall, the pressure on the detection rod gradually increases, meaning the pressure detected by the pressure sensor increases. When the pressure value detected by the pressure sensor reaches a first threshold, the power component stops driving the moving seat, so that the heat shrink handle is stationary, and then the detection rod is extended into the handle again. The depth of the hole is measured or calculated. If the depth of the probe inserted into the hole of the tool holder is greater than the preset range value, it indicates that the heat shrink tool holder is unqualified, that is, the heat shrink tool holder cannot meet the usage requirements. If the depth of the probe inserted into the hole of the tool holder is less than the preset range value, it indicates that the heat shrink tool holder is qualified, that is, the heat shrink tool holder can meet the usage requirements. This completes the detection of the clamping force of the heat shrink tool holder. As a result, the automatic cleaning and detection device for heat shrink tool holders in this application can not only realize the automatic cleaning of the tool holder hole, but also realize the detection of the clamping force of the heat shrink tool holder, thereby improving the efficiency of the detection of the clamping force of the heat shrink tool holder and reducing the detection cost.

[0026] Optionally, a connecting rod is provided between the detection rod and the pressure sensor. The connecting rod has a connecting hole that communicates with the central hole. A tracheal connector that communicates with the connecting hole is provided on the side of the connecting rod. The end of the tracheal connector away from the connecting rod constitutes the air inlet.

[0027] By adopting the above technical solution, since the side of the connecting rod is provided with an air connector that communicates with the connecting hole, and the end of the air connector away from the connecting rod constitutes an air inlet, it is possible to connect the air inlet with an external air supply device. Furthermore, since the connecting rod is provided with a connecting hole that communicates with the central hole, and the air connector is connected to it, high-pressure gas can enter the central hole through the air connector and the connecting hole, thereby delivering high-pressure gas to the detection rod.

[0028] Optionally, the automatic cleaning and detection device for heat shrink tool holders also includes a display screen, on which the pressure value detected by the pressure sensor and the depth of the detection rod inserted into the tool holder hole can be displayed.

[0029] By adopting the above technical solution, the pressure value detected by the pressure sensor and the depth of the test rod inserted into the tool holder can be displayed on the screen, thereby realizing the visibility of the test process and test results. This allows the test process and test results to be presented to the testers more intuitively, enabling the testers to more accurately determine whether the heat shrink tool holder is qualified.

[0030] Optionally, the power component includes a servo motor and a lead screw assembly. The lead screw assembly includes a screw and a nut threadedly connected to the screw. The output shaft of the servo motor is drivenly connected to the screw, and the nut is connected to the movable base.

[0031] By adopting the above technical solution, when the power component needs to drive the moving seat to move, the servo motor is started. The output shaft of the servo motor drives the screw to rotate, so that the nut and the screw rotate relative to each other, and the nut moves along the axial direction of the screw. In turn, the nut drives the moving seat to move along the axial direction of the screw, so as to realize the movement of the moving seat.

[0032] By setting the power component as a combination of a servo motor and a lead screw pair, the stability of the moving seat drive can be increased, and the cost of the power component can be reduced, thereby reducing the production cost of the automatic cleaning and inspection device for heat shrink tool holders. Furthermore, the depth of the detection rod inserted into the tool holder hole can be calculated based on time, the output shaft speed of the servo motor, and the amount of movement of the nut in a single turn of the screw, thus avoiding the need for manual measurement of the depth of the detection rod inserted into the tool holder hole. This further improves the automation level of the automatic cleaning and inspection device for heat shrink tool holders and the efficiency of detecting the clamping force of heat shrink tool holders.

[0033] Optionally, the automatic cleaning and detection device for heat shrink handles further includes a frame, wherein the cleaning component, the air supply channel, and the moving component are all disposed on the frame, and the air supply channel is located above the cleaning component.

[0034] By adopting the above technical solution, since the cleaning component, air supply channel, and moving component are all located on the frame, the cleaning component, air supply channel, and moving component are integrated into the frame, thereby reducing the size of the automatic cleaning and detection device for heat shrink knife handles and facilitating its transport. Furthermore, because the air supply channel is located above the cleaning component, the heat shrink knife handle installed at the mounting position is vertically oriented. This reduces the difficulty of installing and fixing the heat shrink knife handle, increases its stability, and allows dust in the handle hole to detach under its own weight, further improving the cleaning effect on the handle hole.

[0035] Optionally, the automatic cleaning and detection device for heat shrink handles further includes a slide rail mounted on the frame, and the movable seat is provided with a slider slidably connected to the slide rail.

[0036] By adopting the above technical solution, when the moving seat moves under the action of the power component, the moving seat drives the slider to move, which in turn causes the slider and the slide rail to slide relative to each other. The sliding cooperation between the slider and the slide rail guides the movement of the moving seat, thereby increasing the stability of the moving seat during movement. At the same time, the cooperation between the slider and the slide rail can also be used to position the moving seat, thereby increasing the stability of the moving seat and thus increasing the stability of the heat shrink tool holder at the mounting position.

[0037] Optionally, the frame has a shielding side and an operating side on its periphery. The shielding side is provided with a protective plate, and the operating side is provided with a light curtain. The light curtain can send signals to the drive component and the power component to stop the drive component and the power component from working.

[0038] By adopting the above technical solution, the protective plate on the shielding side can isolate the internal space of the frame from the external space, thereby increasing the safety when cleaning the heat shrink tool holder and detecting the clamping force. Furthermore, the light curtain on the operating side can send signals to the drive and power components when the infrared rays emitted by the light curtain are blocked, causing the drive and power components to stop working, which further increases the safety when cleaning the heat shrink tool holder and detecting the clamping force.

[0039] Optionally, the automatic cleaning and detection device for the heat shrink handle also includes a position detector, which can detect the position of the movable seat.

[0040] By adopting the above technical solution, since the position detector can detect the position of the moving seat, the difficulty of calculating the depth of the detection rod inserted into the tool holder hole is reduced, thereby further improving the efficiency of clamping force detection of the heat shrink tool holder. At the same time, it also improves the accuracy of the calculation of the depth of the detection rod inserted into the tool holder hole, thereby further improving the accuracy of the detection results when clamping force is detected on the heat shrink tool holder.

[0041] This application also discloses a cleaning and inspection method to improve the cleaning effect of heat shrink tool holders and reduce the inspection cost of heat shrink tool holders.

[0042] A cleaning and inspection method for use in the automatic cleaning and inspection device for heat shrink knife handles as described above includes the following steps:

[0043] S1. Install the heat shrink tool holder. Install the heat shrink tool holder in the mounting position.

[0044] S2. Clean the heat shrink handle and / or blow out the heat shrink handle;

[0045] S3. The power component drives the moving seat to move away from the sweeping bar, and the pressure sensor collects the pressure value of each sampling cycle.

[0046] S4. When the pressure value reaches the first threshold, the power component stops working. Based on the pressure value and the movement distance of the moving seat, it is determined whether the heat shrink tool holder meets the usage conditions.

[0047] By adopting the above technical solution, the cleaning effect of heat shrink tool holders is improved, the cleaning cost of heat shrink tool holders is reduced, and the clamping force of heat shrink tool holders can be detected, thereby reducing the detection cost of heat shrink tool holders.

[0048] Optionally, the cleaning of the heat shrink handle and / or the blowing of the heat shrink handle includes:

[0049] The power unit and drive unit are activated. The power unit drives the moving seat to move towards the cleaning bar, and the drive unit drives the cleaning bar to rotate, so that the heat shrink blade handle moves to the position of the cleaning bar under the action of the moving seat. The cleaning part extends into the blade handle hole so that the cleaning part cleans the blade handle hole.

[0050] And / or, the power unit drives the moving seat in a direction away from the cleaning bar, and the gas generated by the external air supply device enters the air delivery channel through the air inlet, so that the gas is discharged through the air outlet and enters the tool holder hole to blow the inner wall of the tool holder hole.

[0051] And / or, when the detection rod contacts the end of the heat shrink handle, causing the pressure sensor to reach the second threshold, the external air supply device begins to supply gas to the air delivery channel or the external air supply device increases the gas delivery speed to the air delivery channel.

[0052] Optionally, when the pressure value reaches a first threshold, the power component stops working. Based on the pressure value and the moving distance of the moving seat, it is determined whether the heat shrink tool holder meets the usage conditions, including:

[0053] When the pressure value reaches the second threshold, the position of the moving seat at this time is recorded as the first position h1, and the power unit continues to drive the moving seat in a direction away from the sweeping bar. When the pressure value reaches the first threshold, the position of the moving seat at this time is recorded as the second position h2.

[0054] If the difference between h2 and h1 is within the preset range, then the usage conditions are met; if the difference between h2 and h1 is not within the preset range, then the usage conditions are not met.

[0055] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0056] 1. The automatic cleaning and detection device for heat shrink tool holders in this application includes a cleaning component, an air supply channel, and a moving component. The cleaning component includes a driving component and a cleaning rod connected to the driving component. The driving component drives the cleaning rod to rotate. The cleaning rod is provided with a cleaning part for cleaning the tool holder hole. The air supply channel has an air inlet and an air outlet communicating with the air inlet. The air outlet is arranged opposite to the cleaning rod. The moving component includes a moving base and a power component. The moving base is provided with a mounting position for installing the heat shrink tool holder. The mounting position is located between the air outlet and the cleaning rod. The power component drives the moving base to move between the cleaning component and the air supply channel. Therefore, compared with the solution of manually cleaning the heat shrink tool holder, the technical solution of this application realizes automatic cleaning of the tool holder hole, reduces the labor cost invested in cleaning the tool holder hole, and improves the cleaning efficiency of the tool holder hole, thereby reducing the cleaning cost of the tool holder hole and thus reducing the detection cost of the heat shrink tool holder.

[0057] 2. The movable base in this application has a support plate located between the cleaning rod and the air outlet. The support plate has a through hole for the cleaning part to pass through, and a clamping structure located on the side of the through hole for applying pressure to the heat shrink handle. When installing the heat shrink handle, the heat shrink handle is first placed on the support plate, and the handle hole of the heat shrink handle is made coaxial with the through hole. Then, the clamping structure is used to apply pressure to the heat shrink handle to increase the stability of the heat shrink handle. This avoids the heat shrink handle from rotating with the cleaning part or moving under the action of high pressure gas during the cleaning of the handle hole, thus ensuring the cleaning effect of the heat shrink handle and increasing the safety during the cleaning process of the handle hole.

[0058] 3. The clamping structure in this application includes a rotary cylinder. The piston rod of the rotary cylinder has a lower pressure arm that can contact the end face of the cylindrical portion of the heat shrink tool holder away from the support plate. After the heat shrink tool holder is placed on the support plate, the piston rod of the rotary cylinder rotates, causing the piston rod to drive the lower pressure arm to rotate. This causes at least a portion of the lower pressure arm to be positioned opposite the cylindrical portion of the heat shrink tool holder. Then, the piston rod of the rotary cylinder drives the lower pressure arm to move toward the cylindrical portion of the heat shrink tool holder, ultimately causing the lower pressure arm to contact the end face of the cylindrical portion of the heat shrink tool holder away from the support plate. At the same time, the lower pressure arm, under the action of the piston rod, applies pressure to the cylindrical portion of the heat shrink tool holder toward the side where the support plate is located, thereby achieving the fixation of the heat shrink tool holder.

[0070] Reference Figures 1 to 3 An automatic cleaning and detection device for heat shrink tool handles is disclosed, comprising a cleaning component 1, an air supply channel, and a moving component 2. The cleaning component 1 includes a driving member 11 and a cleaning rod 12 connected to the driving member 11. The driving member 11 drives the cleaning rod 12 to rotate. The cleaning rod 12 is provided with a cleaning part for cleaning the tool handle hole. The air supply channel has an air inlet and an air outlet communicating with the air inlet. The air outlet is disposed opposite to the cleaning rod 12. The moving component 2 includes a moving base 21 and a power member 22. The moving base 21 is provided with a mounting position for mounting the heat shrink tool handle 9. The mounting position is located between the air outlet and the cleaning rod 12. The power member 22 drives the moving base 21 to move between the cleaning component 1 and the air supply channel.

[0071] Before using the automatic cleaning device for heat-shrinkable knife handles in this application, connect the air supply pipe of the external air supply device to the air inlet of the air supply channel so that the external air supply device can deliver high-pressure gas into the air supply channel.

[0072] When cleaning the heat shrink handle 9, first install the heat shrink handle 9 in the mounting position, then start the power unit 22 and the drive unit 11. The power unit 22 drives the movable seat 21, which in turn causes the movable seat 21 to move the heat shrink handle 9 toward the direction of the cleaning assembly 1. The drive unit 11 drives the cleaning rod 12 to rotate. As the movable seat 21 moves toward the direction of the cleaning assembly 1, the cleaning rod 12 eventually extends into the handle hole of the heat shrink handle 9, so that the cleaning part on the cleaning rod 12 cleans the hole wall of the handle hole; the cleaning rod 12 After the cleaning time of the tool holder hole is set, the power unit 22 drives the moving seat 21 in the reverse direction, which in turn causes the moving seat 21 to move the heat shrink tool holder 9 toward the direction of the air supply channel. When the heat shrink tool holder 9 moves to the air outlet, the high-pressure gas in the air supply channel enters the tool holder hole through the air outlet, so as to use the high-pressure gas to blow the hole wall of the tool holder hole. Thus, the tool holder hole is thoroughly cleaned by the combination of the cleaning part and the high-pressure gas, thereby improving the cleaning effect of the heat shrink tool holder 9 and ensuring the accuracy of the detection results when the clamping force of the heat shrink tool holder 9 is tested.

[0073] In addition, compared with the manual cleaning of the heat shrink tool holder 9, the technical solution in this application realizes the automatic cleaning of the tool holder hole, reduces the labor cost invested in cleaning the tool holder hole and improves the cleaning efficiency of the tool holder hole, thereby reducing the cleaning cost of the tool holder hole and thus reducing the inspection cost of the heat shrink tool holder 9.

[0074] This application does not specifically limit the structure of the drive component 11. Preferably, the drive component 11 is a motor, the output shaft of the motor is coaxially arranged with the sweeping rod 12, and the output shaft of the motor is connected to the sweeping rod 12 in a transmission manner, so as to realize that the drive component 11 drives the sweeping rod 12 to rotate.

[0075] This application does not specify a particular method for the transmission connection between the motor's output shaft and the cleaning rod 12. Preferably, the motor's output shaft is connected to the cleaning rod 12 via a drill chuck to facilitate the replacement of the cleaning rod 12. In other embodiments, the motor's output shaft may also be connected to the cleaning rod 12 via a coupling or welding.

[0076] In other embodiments, the drive element 11 may also be a pneumatic motor or other structure capable of driving the sweeping rod 12 to rotate.

[0077] This application does not specifically limit the structure of the cleaning part. Preferably, the cleaning part is a brush provided on the outer peripheral surface of the end of the cleaning rod 12 away from the drive member 11, so that the brush can be inserted into the handle hole and rotate with the cleaning rod 12 to clean the handle hole. In other embodiments, the cleaning part may also be a sponge or other structure provided on the outer peripheral surface of the cleaning rod 12.

[0078] This application does not specify the method by which the heat-shrink tool holder 9 is fixed to the mounting position; preferably, refer to... Figure 1 and Figure 2 The movable base 21 has a support plate 211 located between the cleaning rod 12 and the air outlet. The support plate 211 is provided with a through hole for the cleaning part to pass through, and the support plate 211 is provided with a clamping structure located on the side of the through hole for applying pressure to the heat shrink handle 9.

[0079] It is understandable that the through hole is coaxial with the cleaning rod 12, and the diameter of the through hole is larger than the diameter of the cleaning rod 12.

[0080] When installing the heat shrink handle 9, first place the heat shrink handle 9 on the support plate 211, ensuring that the handle hole and the through hole of the heat shrink handle 9 are coaxial. Then, apply pressure to the heat shrink handle 9 using the clamping structure to increase its stability. This prevents the heat shrink handle 9 from rotating with the cleaning unit or moving under the action of high-pressure gas during the cleaning of the handle hole, thus ensuring the cleaning effect of the heat shrink handle 9 and increasing the safety during the cleaning process.

[0081] Since the support plate 211 is provided with a through hole for the cleaning part to pass through, the cleaning part can be extended into the tool holder hole through the through hole, so as to ensure that the cleaning part can pass through the support plate 211 and enter the tool holder hole.

[0082] This application does not specifically limit the clamping structure; however, preferred options are described below. Figure 1 and Figure 2 The clamping structure includes a rotary cylinder 212, the piston rod of which has a lower pressure arm that can contact the end face of the cylindrical portion of the heat shrink handle 9 away from the support plate 211.

[0083] After the heat shrink tool holder 9 is placed on the support plate 211, the piston rod of the angle cylinder 212 rotates, causing the piston rod to drive the lower pressure arm to rotate. This causes at least a portion of the lower pressure arm to be positioned opposite the cylindrical portion of the heat shrink tool holder 9. Then, the piston rod of the angle cylinder 212 drives the lower pressure arm to move towards the cylindrical portion of the heat shrink tool holder 9, ultimately causing the lower pressure arm to contact the end face of the cylindrical portion of the heat shrink tool holder 9 away from the support plate 211. At the same time, the lower pressure arm, under the action of the piston rod, applies pressure to the cylindrical portion of the heat shrink tool holder 9 towards the side where the support plate 211 is located, thereby achieving the fixation of the heat shrink tool holder 9.

[0084] By setting the clamping structure as a rotary cylinder 212, the clamping structure is simplified, the cost of the clamping structure is reduced, and the production cost of the heat shrink tool holder automatic cleaning and detection device is reduced.

[0085] The better one is to refer to Figure 1 and Figure 2 There are two corner cylinders 212, which are located on both sides of the through hole to increase the pressure points on the heat shrink handle 9, thereby further increasing the stability of the heat shrink handle 9 after it is installed in the mounting position.

[0086] Preferably, a pressure rod is provided at the end of the lower pressure arm away from the piston rod. The pressure rod is located on the side of the lower pressure arm facing the support plate 211, and a rubber sleeve is provided at the end of the pressure rod away from the lower pressure arm. This allows the lower pressure arm to contact the cylindrical part of the heat shrink tool holder 9 through the rubber sleeve on the pressure rod, so as to avoid the lower pressure arm from making hard contact with the cylindrical part of the heat shrink tool holder 9 and causing damage to the heat shrink tool holder 9.

[0087] In other embodiments, the clamping structure may also include a cylinder and a pressure ring, the pressure ring being disposed on the piston rod of the cylinder, and the pressure ring being able to be sleeved on the outside of the heat shrink handle 9 and apply pressure to the cylindrical portion of the heat shrink handle 9 toward the side where the support plate 211 is located.

[0088] In other embodiments, the heat shrink handle 9 can be fixedly connected to the mounting position by combining the ring structure and the bolt. That is, the ring structure is sleeved on the outside of the heat shrink handle 9 and abuts against the cylindrical part of the heat shrink handle 9. One end of the bolt passes through the ring structure and is threaded to the support plate 211, so that the bolt head can apply pressure to the ring structure toward the side where the support plate 211 is located.

[0089] This application does not specify the method of forming the mounting position; preferably, refer to... Figure 1 and Figure 2 The support plate 211 is provided with a support body 213, and the support body 213 is provided with a receiving hole coaxially arranged with the through hole. At least a portion of the heat shrink handle 9 can extend into the receiving hole so that the support body 213 constitutes a mounting position.

[0090] Understandably, the receiving hole passes through the support body 213, and the shape of the receiving hole is adapted to the shape of the part of the heat shrink tool holder 9 that can extend into the receiving hole, so that after the heat shrink tool holder 9 is installed in the mounting position, the part of the heat shrink tool holder 9 located in the receiving hole abuts against the hole wall of the receiving hole, and the cylindrical part of the heat shrink tool holder 9 abuts against the end of the support body 213 away from the support plate 211, so as to use the support body 213 to support and position the heat shrink tool holder 9.

[0091] When placing the heat shrink tool holder 9 in the mounting position, align the heat shrink tool holder 9 with the receiving hole, and then apply pressure to the side of the receiving hole so that at least a portion of the heat shrink tool holder 9 extends into the receiving hole. Since the receiving hole and the through hole are coaxially arranged, after at least a portion of the heat shrink tool holder 9 is extended into the receiving hole, the tool holder hole of the heat shrink tool holder 9 is automatically coaxial with the through hole, so as to realize the positioning of the heat shrink tool holder 9 by using the receiving hole, thereby reducing the installation difficulty of the heat shrink tool holder 9 and further improving the cleaning efficiency of the tool holder hole.

[0092] In other embodiments, the mounting position may also be a space on the support plate 211 that can accommodate the heat shrink handle 9, or at least a portion of the heat shrink handle 9 can extend into the through hole, so that the through hole constitutes the mounting position.

[0093] In a preferred embodiment, refer to Figure 1 and Figure 2 The automatic cleaning and detection device for heat shrink handles also includes a detection rod 3 that can extend into the handle hole. The detection rod 3 is coaxially arranged with the cleaning rod 12. The detection rod 3 has a central hole, and the end of the central hole near the cleaning rod 12 forms an air outlet.

[0094] It is understandable that after the heat shrink handle 9 is installed in the mounting position, the heat shrink handle 9, the cleaning rod 12, and the detection rod 3 are in a coaxial state.

[0095] Since the detection rod 3 can be inserted into the tool handle hole, and the end of the central hole near the cleaning rod 12 forms an air outlet, the air outlet can be inserted into the inside of the tool handle hole to improve the cleaning effect of the high-pressure gas discharged through the air outlet on the tool handle hole, thereby further improving the accuracy of the detection results when detecting the clamping force of the heat shrink tool handle 9.

[0096] Preferably, the end of the detection rod 3 near the cleaning rod 12 is provided with a chamfer, so that the chamfer at the end of the detection rod 3 can be used to guide the detection rod 3, so as to facilitate the end of the detection rod 3 to extend into the tool holder hole.

[0097] Furthermore, refer to Figure 1 A pressure sensor 4 is provided at the end of the detection rod 3 that is away from the cleaning rod 12. The pressure sensor 4 can detect the pressure on the detection rod 3.

[0098] It is understandable that when the detection rod 3 is subjected to pressure, the detection rod 3 will apply pressure to the pressure sensor 4, and the pressure sensor 4 and the detection rod 3 are subjected to the same pressure, so that the pressure on the detection rod 3 is the same as the pressure on the pressure sensor 4, thereby realizing the detection of the pressure on the detection rod 3.

[0099] It should be noted that the detection rod 3 is equivalent to a tool that needs to be installed on the heat shrink tool holder 9. When the detection rod 3 is inserted into the heat shrink tool holder 9, the outer peripheral surface of the detection rod 3 will contact the hole wall of the tool holder hole, and one of them will have a large resistance.

[0100] When the heat shrink handle 9 moves to the position of the detection rod 3 under the drive of the movable seat 21, the power unit 22 continues to drive the movable seat 21, so that the movable seat 21 continues to drive the heat shrink handle 9 in the direction away from the cleaning rod 12, thereby causing the detection rod 3 to gradually extend into the handle hole. Due to the friction between the detection rod 3 and the hole wall, the pressure on the detection rod 3 gradually increases, that is, the pressure detected by the pressure sensor 4 becomes larger and larger. When the pressure value detected by the pressure sensor 4 reaches the first threshold, the power unit 22 stops driving the movable seat 21, so that the heat shrink handle 9 is in a stationary state, and then the detection rod 3 is extended into the hole. The depth of the tool holder hole is measured or calculated. If the depth of the probe 3 inserted into the tool holder hole is greater than the preset range value, it indicates that the heat shrink tool holder 9 is unqualified, that is, the heat shrink tool holder 9 cannot meet the usage requirements. If the depth of the probe 3 inserted into the tool holder hole is less than the preset range value, it indicates that the heat shrink tool holder 9 is qualified, that is, the heat shrink tool holder 9 can meet the usage requirements. This completes the detection of the clamping force of the heat shrink tool holder 9. As a result, the automatic cleaning and detection device for heat shrink tool holders in this application can not only realize the automatic cleaning of the tool holder hole, but also realize the detection of the clamping force of the heat shrink tool holder 9, thereby improving the efficiency of the detection of the clamping force of the heat shrink tool holder 9 and reducing the detection cost.

[0101] Furthermore, refer to Figure 1 A connecting rod 5 is provided between the detection rod 3 and the pressure sensor 4. The connecting rod 5 has a connecting hole that communicates with the central hole. The side of the connecting rod 5 has a tracheal connector that communicates with the connecting hole. The end of the tracheal connector away from the connecting rod 5 forms an air inlet.

[0102] It is understandable that the detection rod 3 is connected to the pressure sensor 4 via the connecting rod 5, and the channel, connecting hole and central hole inside the tracheal connector together constitute the air delivery channel.

[0103] Because the side of the connecting rod 5 is provided with an air connector that communicates with the connecting hole, and the end of the air connector away from the connecting rod 5 forms an air inlet, it is convenient to connect the air inlet with the external air supply equipment; and because the connecting rod 5 is provided with a connecting hole that communicates with the central hole, and the air connector is connected to it, high-pressure gas can enter the central hole through the air connector and the connecting hole, so as to deliver high-pressure gas to the detection rod 3.

[0104] Of course, in other embodiments, the detection rod 3 can be omitted and an air pipe can be provided so that the internal channel of the air pipe constitutes an air supply channel, or the end of the air supply pipe of the external air supply device can be located above the movable seat 21 so that the air supply pipe of the external air supply device constitutes an air supply channel.

[0105] In a preferred embodiment, refer to Figures 1 to 3 The automatic cleaning and detection device for heat shrink tool holders also includes a display 6, on which the pressure value detected by the pressure sensor 4 and the depth of the detection rod 3 inserted into the tool holder hole can be displayed.

[0106] Since the pressure value detected by the pressure sensor 4 and the depth of the probe 3 inserted into the tool holder can be displayed on the display 6, the detection process and the detection results are made visible, so that the detection process and the detection results can be presented to the inspectors more intuitively, thereby enabling the inspectors to more accurately judge whether the heat shrink tool holder 9 is qualified.

[0107] In a preferred embodiment, the automatic cleaning and detection device for heat-shrinkable tool holders further includes a programmable logic controller (PLC). The drive unit 11, power unit 22, and pressure sensor 4 are all electrically connected to the PLC. The PLC can control the start and stop of the drive unit 11 and power unit 22, and the pressure sensor 4 can send signals to the PLC. The PLC is electrically connected to a display 6 so that the pressure received by the pressure sensor 4 can be processed by the PLC and displayed on the display 6. Furthermore, the PLC can calculate and measure the depth of the detection rod 3 inserted into the tool holder hole based on the working time and rotation speed of the power unit 22, and display the calculated result on the display 6; or the position sensor can send the position information of the moving base 21 to the PLC, which then converts the position information into the depth of the detection rod 3 inserted into the tool holder hole and displays it on the display 6.

[0108] This application does not specifically limit the structure of the power component 22; however, preferred embodiments are described below. Figure 1 and Figure 2 The power component 22 includes a servo motor 221 and a lead screw pair 222. The lead screw pair 222 includes a screw and a nut threaded to the screw. The output shaft of the servo motor 221 is driven to the screw, and the nut is connected to the moving base 21.

[0109] Understandably, the screw is set parallel to the cleaning rod 12, and the nut is fixedly connected to the movable seat 21.

[0110] When the power component 22 is needed to drive the moving seat 21 to move, the servo motor 221 is started. The output shaft of the servo motor 221 drives the screw to rotate, so that the nut and the screw rotate relative to each other, and the nut moves along the axial direction of the screw. In turn, the nut drives the moving seat 21 to move along the axial direction of the screw, so as to realize the movement of the moving seat 21.

[0111] By setting the power component 22 as a combination of servo motor 221 and lead screw pair 222, the stability of driving the moving seat 21 can be increased, and the cost of the power component 22 can be reduced, thereby reducing the production cost of the automatic cleaning and detection device for heat shrink tool holders. Furthermore, the depth of the detection rod 3 inserted into the tool holder hole can be calculated based on time, the output shaft speed of servo motor 221, and the amount of movement of the nut in a single turn of the screw, so as to avoid the need for manual measurement of the depth of the detection rod 3 inserted into the tool holder hole. This further improves the automation level of the automatic cleaning and detection device for heat shrink tool holders and further improves the efficiency of detecting the clamping force of heat shrink tool holder 9.

[0112] This application does not specify a particular method for the transmission connection between the output shaft of the servo motor 221 and the screw. Preferably, the output shaft of the servo motor 221 is connected to the screw via a coupling to ensure the stability of the transmission connection between the output shaft of the servo motor 221 and the screw. In other embodiments, the output shaft of the servo motor 221 can also be connected to the screw in other ways, such as by welding.

[0113] In other embodiments, the power component 22 may also be a linear motor, cylinder, hydraulic cylinder, electric actuator, or other structure capable of driving the movable seat 21 to move.

[0114] In a preferred embodiment, refer to Figures 1 to 3 The automatic cleaning and detection device for heat shrink handles also includes a frame 7, a cleaning component 1, an air supply channel and a moving component 2, all of which are located on the frame 7, with the air supply channel located above the cleaning component 1.

[0115] It is understandable that the gas delivery channel and the cleaning component 1 are arranged sequentially in the vertical direction.

[0116] Since the cleaning component 1, the air supply channel, and the moving component 2 are all located on the frame 7, the cleaning component 1, the air supply channel, and the moving component 2 are all integrated into the frame 7, thereby reducing the size of the automatic cleaning and detection device for heat shrink knife handles and facilitating its transport. Furthermore, because the air supply channel is located above the cleaning component 1, the heat shrink knife handle 9 installed at the mounting position is vertically oriented. This reduces the difficulty of installing and fixing the heat shrink knife handle 9, increases its stability, and allows dust in the handle hole to detach under its own weight, further improving the cleaning effect on the handle hole.

[0117] Specifically, the frame 7 has an internal installation space, the cleaning component 1 and the air supply component are located inside the installation space, the pressure sensor 4 is fixedly connected to the frame 7 and located at the upper part of the installation space, the drive component 11 is fixedly connected to the frame 7 and located at the lower part of the installation space, the moving base 21 is located inside the installation space, the servo motor 221 is located outside the installation space and fixedly connected to the frame 7, and the bottom of the frame 7 has support legs to support the frame 7.

[0118] Furthermore, refer to Figures 1 to 3 The automatic cleaning and detection device for heat shrink handles also includes a slide rail 71 mounted on the frame 7, and a slider 214 slidably connected to the slide rail 71 on the movable seat 21.

[0119] It is understandable that the length direction of the slide rail 71 is parallel to the axial direction of the sweeping rod 12.

[0120] When the movable seat 21 moves under the action of the power component 22, the movable seat 21 drives the slider 214 to move, which in turn causes the slider 214 to slide relative to the slide rail 71. The sliding cooperation between the slider 214 and the slide rail 71 guides the movement of the movable seat 21, thereby increasing the stability of the movable seat 21 during movement. At the same time, the cooperation between the slider 214 and the slide rail 71 can also be used to position the movable seat 21, thereby increasing the stability of the movable seat 21 and thus increasing the stability of the heat shrink tool holder 9 at the mounting position.

[0121] Preferably, there are two slide rails 71 spaced apart, and two sliders 214 are provided on the movable seat 21. The sliders 214 are arranged in a one-to-one correspondence with the slide rails 71 to further increase the stability of the movable seat 21 during movement.

[0122] Furthermore, refer to Figures 1 to 3 The frame 7 has a shielding side and an operating side around its perimeter. The shielding side is provided with a protective plate 72, and the operating side is provided with a light curtain 73. The light curtain 73 can send signals to the drive unit 11 and the power unit 22 to stop the drive unit 11 and the power unit 22 from working.

[0123] It should be noted that the light curtain 73 is a safety protection device based on the photoelectric sensing principle. It forms a detection area by emitting infrared rays, and triggers a stop signal when the infrared rays are blocked.

[0124] Because the shielding side is equipped with a protective plate 72, the internal space of the frame 7 can be isolated from the external space, thereby increasing the safety when cleaning the heat shrink tool holder 9 and detecting the clamping force. Furthermore, because the operating side is equipped with a light curtain 73, when the infrared light emitted by the light curtain 73 is blocked, the light curtain 73 can send a signal to the drive unit 11 and the power unit 22 to stop the drive unit 11 and the power unit 22 from working, thereby further increasing the safety when cleaning the heat shrink tool holder 9 and detecting the clamping force.

[0125] Specifically, the light curtain 73 is located in the lower part of the mounting space of the rack 7, and the light curtain 73 emits infrared rays upward. The light curtain 73 is electrically connected to the programmable logic controller. That is, when the infrared rays emitted by the light curtain 73 are blocked, the light curtain 73 sends a signal to the programmable logic controller, and then the programmable logic controller sends a stop signal to the drive unit 11 and the power unit 22.

[0126] Of course, in other embodiments, the gas delivery channel and the cleaning component 1 can also be arranged sequentially in the horizontal direction.

[0127] In a preferred embodiment, the heat shrink handle automatic cleaning and detection device further includes a position detector, which can detect the position of the movable seat 21.

[0128] Since the position detector can detect the position of the moving seat 21, it reduces the difficulty of calculating the depth of the detection rod 3 inserted into the tool holder hole, thereby further improving the efficiency of clamping force detection of the heat shrink tool holder 9. At the same time, it also improves the accuracy of the calculation of the depth of the detection rod 3 inserted into the tool holder hole, thereby further improving the accuracy of the detection results when clamping force is detected on the heat shrink tool holder 9.

[0129] This application does not specifically limit the structure of the position detector; preferably, refer to... Figure 2 The position sensor 8 includes a photoelectric transmitter 81 mounted on the frame 7 and a receiver 82 mounted on the movable seat 21. When the receiver 82 is opposite to the photoelectric transmitter 81, it can receive the light signal emitted by the photoelectric transmitter 81. The position of the receiver 82 relative to the photoelectric transmitter 81 is defined as the initial position of the movable seat 21. In this position, the heat shrink handle 9 installed in the mounting position does not interfere with the detection rod 3 and the cleaning rod 12. That is, in the initial position, the heat shrink handle 9 can be installed in the mounting position or removed from the mounting position.

[0130] Specifically, receiver 82 is electrically connected to programmable logic controller (PLC). When receiver 82 receives the light signal emitted by photoelectric transmitter 81, receiver 82 sends a signal to PLC so that PLC can control other components according to the signal from receiver 82.

[0131] In other embodiments, the position sensor 8 may also be a ranging sensor, and the ranging sensor is installed in the lower part of the mounting space of the frame 7 so that the distance between the moving base 21 and the ranging sensor can be directly measured using the ranging sensor; of course, the position sensor 8 may also be other electrical devices such as a proximity switch.

[0132] A cleaning and inspection method for use in the automatic cleaning and inspection device for heat shrink knife handles as described above includes the following steps:

[0133] S1. Install the heat shrink tool holder 9. Install the heat shrink tool holder 9 in the mounting position.

[0134] S2. Clean the heat shrink handle 9 and / or blow out the heat shrink handle 9;

[0135] S3, the power component 22 drives the moving seat 21 to move away from the sweeping bar 12, and the pressure sensor 4 collects the pressure value of each sampling cycle;

[0136] S4. When the pressure value reaches the first threshold, the power component stops working. Based on the pressure value and the movement distance of the moving seat, it is determined whether the heat shrink tool holder meets the usage conditions.

[0137] The aforementioned cleaning heat shrink handle 9 and / or blowing heat shrink handle 9 can be implemented using any combination of one or more of the following embodiments:

[0138] In the first embodiment, the power unit 22 and the drive unit 11 are activated. The power unit 22 drives the moving seat 21 to move toward the direction close to the cleaning rod 12, and the drive unit 11 drives the cleaning rod 12 to rotate, so that the heat shrink handle 9 moves to the position of the cleaning rod 12 under the action of the moving seat 21. The cleaning part extends into the handle hole so that the cleaning part cleans the handle hole.

[0139] In the second embodiment, the power unit 22 drives the moving seat 21 in a direction away from the cleaning rod 12. The gas generated by the external air supply device enters the air delivery channel through the air inlet, so that the gas is discharged through the air outlet and enters the tool holder hole to blow the inner wall of the tool holder hole.

[0140] In the third embodiment, when the detection rod 3 contacts the end of the heat shrink handle 9 and the pressure sensor 4 reaches the second threshold, the external gas supply device starts to supply gas to the gas delivery channel or the external gas supply device increases the gas delivery speed of the gas delivery channel.

[0141] Preferably, a combination of sweeping and blowing is used to clean the heat shrink handle 9. When cleaning the heat shrink handle 9, the power unit 22 first drives the moving base 21 to move towards the direction of the sweeping rod 12, so that the sweeping part of the sweeping rod 12 extends into the handle hole of the heat shrink handle 9. After the sweeping part has cleaned the handle hole for a set time, the power unit 22 drives the moving base 21 to move towards the direction of the air supply channel, and then the gas is used to blow the handle hole of the heat shrink handle 9.

[0142] It should be noted that while the cleaning unit is cleaning the tool holder hole, the power unit 22 drives the moving seat 21 to reciprocate in the direction of approaching and moving away from the air supply channel, and the distance of the reciprocating motion is equal to the depth of the tool holder hole, so as to further improve the cleaning effect of the tool holder hole.

[0143] When the pressure value reaches the first threshold, the power component 22 stops working. Based on the pressure value and the moving distance of the moving seat 21, it is determined whether the heat shrink tool holder 9 meets the usage conditions, including:

[0144] When the pressure value reaches the second threshold, the position of the moving seat 21 at this time is recorded as the first position h1, and the power unit 22 continues to drive the moving seat 21 in a direction away from the sweeping bar 12. When the pressure value reaches the first threshold, the position of the moving seat 21 at this time is recorded as the second position h2.

[0145] If the difference between h2 and h1 is within the preset range, then the usage conditions are met; if the difference between h2 and h1 is not within the preset range, then the usage conditions are not met.

[0146] Understandably, the first threshold is greater than the second threshold. The first threshold can be determined based on the model of the heat shrink handle 9, while the second threshold can be determined based on the accuracy of the pressure sensor 4.

[0147] This application does not specify the method by which the programmable logic controller calculates the moving distance of the movable seat 21. When the position sensor 8 is a ranging sensor, the programmable logic controller can directly determine the moving distance of the movable seat 21 based on the distance signal detected by the ranging sensor. When the position sensor 8 is a combination of a photoelectric transmitter 81 and a receiver 82, and the power component 22 is a combination of a servo motor 221 and a lead screw pair 222, the programmable logic controller can determine the number of rotations of the output shaft of the servo motor 221 based on the start-up time and speed of the servo motor 221, and then determine the moving distance of the movable seat 21 by combining the moving distance of the nut when the screw rotates one revolution.

[0148] It should be noted that when the first position h1 and the second position h2 are obtained by the ranging sensor, the first position h1 and the second position h2 refer to the distance between the moving base 21 and the ranging sensor when it is in the first position and the distance between the moving base 21 and the ranging sensor when it is in the second position, respectively.

[0149] When the first position h1 and the second position h2 are obtained by calculating the working time of the servo motor 221, the rotation speed of the servo motor 221, and the distance the nut moves in one revolution of the screw, the first position h1 and the second position h2 respectively refer to the distance the moving seat 21 needs to move from the initial position to the first position and the distance the moving seat 21 needs to move from the initial position to the second position. In this method, after the cleaning time of the cleaning part on the knife handle hole reaches the set time, the power unit 22 drives the moving seat 21 to move towards the direction close to the air supply channel. During the movement of the moving seat 21 towards the direction close to the air supply channel, the moving seat 21 will pass through the initial position. The receiver 82 is capable of receiving the photoelectric signal emitted by the photoelectric transmitter 81, and the receiver 82 transmits the signal to the programmable logic controller (PLC). The time from the time the PLC sends the signal to the PLC until the pressure value of the pressure sensor 4 reaches the second threshold is defined as the working time of the servo motor 221 required for the moving seat 21 to move from the initial position to the first position. The time from the time the receiver 82 sends the signal to the PLC until the pressure sensor 4 reaches the first threshold is defined as the working time of the servo motor 221 required for the moving seat 21 to move from the initial position to the second position.

[0150] Of course, in the above scheme of obtaining the movement distance of the moving seat 21 by the working time of the servo motor 221, the rotation speed of the servo motor 221, and the movement distance of the nut when the lead screw rotates one revolution, the depth of the detection rod 3 inserted into the tool holder hole can also be obtained by calculating the time from when the pressure value of the pressure sensor 4 reaches the second threshold and sends a signal to the programmable logic controller to when the pressure value of the pressure sensor 4 reaches the first threshold, combined with the rotation speed of the servo motor 221 during this time and the movement distance of the nut when the lead screw rotates one revolution.

[0151] Of course, in other embodiments, the setting of the second threshold can be cancelled, and a proximity switch located on the side of the heat shrink handle 9 can be provided on the frame 7. When the end of the heat shrink handle 9 away from the support plate 211 is flush with the end of the detection rod 3 near the support plate 211, the proximity switch sends a signal to the programmable logic controller so that the programmable logic controller records the position of the moving seat 21 at this time as the first position.

[0152] In a preferred embodiment, the cleaning and detection method further includes step S6, resetting and disassembling the tool. The power unit 22 drives the moving seat 21 in a direction away from the detection rod 3 so that the moving seat 21 moves to the initial position, the heat shrink handle 9 separates from the detection rod 3, and the heat shrink handle 9 is disassembled.

[0153] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0154] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
