[0002] The continuous coating equipment forms a pipeline coating structure by connecting multiple coating chambers, and realizes the coating operation of the workpiece by sequentially moving the hanger in the multiple coating chambers.

[0003] In existing continuous coating equipment, when the hanger enters a coating chamber, a stop structure is needed to stop the movement of the hanger. Usually, the stop structure is located close to the exit of the coating chamber. When the end of the hanger abuts against the stop structure, the movement of the hanger can be stopped, so that subsequent coating operations can continue.

[0004] However, the contact between the stopper structure and the rack used at the current stage is hard contact. After multiple contacts, the stopper structure is easily damaged or bent, causing deviation in the stop position of the rack, affecting the coating accuracy and effect.

[0005] Therefore, there is an urgent need to provide an in-place detection device and a continuous coating device to solve the problems existing in the prior art to a certain extent. Utility Model Content

[0009] Specifically, the rolling assembly includes a connecting shaft and a bearing, the connecting shaft is connected to the connecting rod, and the bearing is connected to the connecting shaft.

[0010] Specifically, the in-place detection device provided by the utility model also includes a positioning component, which includes a fixed tube and a sleeve, the fixed tube is a hollow structure, the fixed tube is sleeved outside the connecting rod, and one end of the fixed tube is connected to the base plate; the sleeve is arranged at one end of the fixed tube close to the rolling component and is sleeved on the connecting rod, and the connecting rod can slide relative to the sleeve.

[0011] Furthermore, a limiting portion is formed in the fixing tube at a position corresponding to the abutting portion, and the limiting portion and the accommodating groove form a sliding space.

[0012] Furthermore, the positioning assembly also includes a dust cover, which is arranged on the outside of the shaft sleeve. The connecting rod passes through the dust cover and can slide relative to the dust cover.

[0013] Among them, the in-place detection device provided by the utility model also includes a push plate, which is connected to the end of the connecting rod away from the coating chamber, the shielding member is connected to the push plate, and a sealing sleeve is connected between the substrate and the push plate, and the end of the connecting rod away from the rolling assembly passes through the substrate into the sealing sleeve and is connected to the push plate.

[0014] Specifically, the in-place detection device provided by the utility model also includes a guide assembly, which includes a guide rod, one end of which is connected to the base plate, and the other end is arranged through the push plate, the axis of the guide rod is parallel to the axis of the connecting rod, and the push plate can slide along the guide rod.

[0016] Compared with the prior art, the in-place detection device provided by the utility model has the following advantages:

[0017] The utility model provides an in-position detection device for continuous coating equipment, comprising a connecting rod, an elastic member, a substrate, a shielding member and a photoelectric detection member; the connecting rod extends in a vertical direction, one end of the connecting rod is located in the coating cavity of the continuous coating equipment and can contact with the hanger, the other end of the connecting rod is arranged through the substrate, the connecting rod can slide relative to the substrate, the elastic member is sleeved on the connecting rod, and an abutment portion is formed on the connecting rod, one end of the elastic member abuts against the abutment portion, a receiving groove is formed on the substrate, and the other end of the elastic member abuts against the receiving groove; one end of the connecting rod passes through the substrate and is connected to the shielding member, and the photoelectric detection member is arranged corresponding to the shielding member.

[0018] From this analysis, it can be known that by sleeve-arranging an elastic member on the connecting rod, and forming an abutment portion on the connecting rod at a position corresponding to the elastic member, it is possible to limit one end of the elastic member, and by making the end of the connecting rod away from the coating cavity pass through the substrate, and making the connecting rod slide relative to the substrate, and forming a receiving groove on the substrate, so that the other end of the elastic member abuts against the receiving groove, therefore, when the hanger and the connecting rod are located at the junction of one end in the coating cavity, the connecting rod can be pressed down, so that the connecting rod moves down in the vertical direction, and the elastic member is compressed at the same time. When the hanger moves out of the coating cavity and the connecting rod is separated from the hanger, the connecting rod can be reset to the initial position again under the driving force of the elastic member to wait for the next hanger to move in.

[0019] Since a blocking member is connected to one end of the connecting rod passing through the base plate, when the connecting rod is pressed and moved downward, the blocking member can be driven to move downward. Since the photoelectric detection member is arranged corresponding to the blocking member, when the blocking member moves downward, the photoelectric detection member can be blocked, so that the photoelectric detection member can be used to detect that the hanger is in place.

[0020] It can be understood that since the detection of the placement of the hanger in the present application utilizes the reciprocating motion of the connecting rod in the vertical direction, no collision occurs, thereby being able to avoid to a certain extent the problem of the current stop structure being bent after long-term use, resulting in inaccurate positioning of the hanger and affecting the coating effect and accuracy.

[0021] In addition, the utility model also provides a continuous coating equipment, including multiple coating chambers, a hanger and the above-mentioned in-place detection device; the substrate of the in-place detection device is connected to the bottom wall of the coating chamber, and the end of the connecting rod away from the shielding member is located in the coating chamber and can contact the bottom of the hanger.

[0036] like Figure 1 As shown, the utility model provides an in-position detection device for continuous coating equipment, including a connecting rod 1, an elastic member 8, a substrate 7, a shielding member 11 and a photoelectric detection member 12; the connecting rod 1 extends in a vertical direction, one end of the connecting rod 1 is located in a coating cavity 15 of the continuous coating equipment, and can contact with a rack, the other end of the connecting rod 1 is arranged through the substrate 7, the connecting rod 1 can slide relative to the substrate 7, the elastic member 8 is sleeved on the connecting rod 1, and an abutment portion 101 is formed on the connecting rod 1, one end of the elastic member 8 abuts against the abutment portion 101, a receiving groove 701 is formed on the substrate 7, and the other end of the elastic member 8 abuts against the receiving groove 701; one end of the connecting rod 1 passes through the substrate 7 and is connected to the shielding member 11, and the photoelectric detection member 12 is arranged corresponding to the shielding member 11.

[0037] Compared with the prior art, the in-place detection device provided by the utility model has the following advantages:

[0038] The in-position detection device provided by the utility model can limit one end of the elastic member 8 by sleeve-arranging the elastic member 8 on the connecting rod 1, and forming an abutment portion 101 on the connecting rod 1 at a position corresponding to the elastic member 8, and by making the end of the connecting rod 1 away from the coating cavity 15 pass through the substrate 7, and making the connecting rod 1 slide relative to the substrate 7, and forming a receiving groove 701 on the substrate 7, so that the other end of the elastic member 8 abuts against the receiving groove 701, so that when the hanger and the connecting rod 1 are at the junction of one end in the coating cavity 15, the connecting rod 1 can be pressed down, so that the connecting rod 1 moves down in the vertical direction, and the elastic member 8 is compressed at the same time. When the hanger moves out of the coating cavity 15 and the connecting rod 1 is separated from the hanger, the connecting rod 1 can be reset to the initial position again under the driving of the restoring force of the elastic member 8, waiting for the next hanger to move in.

[0039] Since the connecting rod 1 passes through one end of the substrate 7 and is connected to the shielding member 11, when the connecting rod 1 is pressed and moved downward, it can drive the shielding member 11 to move downward. Since the photoelectric detection member 12 is arranged corresponding to the shielding member 11, when the shielding member 11 moves downward, it can block the photoelectric detection member 12, so that the photoelectric detection member 12 can be used to detect that the hanger is delivered to the place.

[0040] It can be understood that since the detection of the placement of the hanger in the present application utilizes the reciprocating motion of the connecting rod 1 in the vertical direction, no collision occurs, thereby being able to avoid to a certain extent the problem of the current stop structure being bent after long-term use, resulting in inaccurate positioning of the hanger and affecting the coating effect and accuracy.

[0041] It should be noted here that since the elastic member 8 in the present application is sleeved on the outside of the connecting rod 1, and the connecting rod 1 needs to be able to slide relative to the elastic member 8, preferably, the elastic member 8 in the present application adopts a coil spring, which can not only realize the automatic rebound of the connecting rod 1 after losing the pressure of the bracket, but also realize the smooth up and down movement of the connecting rod 1.

[0042] The use of a coil spring is only one of the implementation methods. An elastic ring made of rubber or silicone material can also be set between the abutment portion 101 of the connecting rod 1 and the accommodating groove 701. When pressed down, the elastic ring is compressed and deformed, and returns to its original state after the pressure is lost, thereby realizing automatic up and down movement of the connecting rod 1.

[0043] Alternatively, if Figure 1 As shown, the in-place detection device provided by the utility model further includes a rolling assembly, which is arranged at one end of the connecting rod 1 away from the push plate 10, and the rolling assembly can rotate relative to the connecting rod 1.

[0044] Since the hanger of the continuous coating equipment moves from one end to the other end of the coating chamber 15, a rolling assembly is arranged at one end of the connecting rod 1 located in the coating chamber 15. When the hanger reaches the position of the connecting rod 1, it contacts the rolling assembly. Since the rolling assembly can rotate relative to the connecting rod 1, the hanger can be guided and the connecting rod 1 can be moved downward.

[0045] It can be understood that after the rolling component is set, the friction between the hanger and the connecting rod 1 during movement can be avoided by rolling the rolling component, which can not only make the movement of the hanger smoother, but also avoid the problem of excessive friction between the connecting rod 1 and the hanger causing damage to the connecting rod 1 or the hanger.

[0046] Preferably, if Figure 1 As shown, the rolling assembly in the present application includes a connecting shaft 3 and a bearing 2 , the connecting shaft 3 is connected to the connecting rod 1 , and the bearing 2 is connected to the connecting shaft 3 .

[0047] The present application provides an implementation method of a rolling assembly, which is connected to the connecting rod 1 by a connecting shaft 3, and the inner ring of the bearing 2 is connected to the connecting shaft 3, so that the connection between the bearing 2 and the connecting rod 1 can be achieved. Accordingly, through the contact between the outer ring of the bearing 2 and the bracket, when the bracket moves, it can drive the outer ring of the bearing 2 to rotate, thereby greatly reducing the friction between the bracket and the in-place detection device provided by the present application, ensuring the smooth operation of the structure.

[0048] Alternatively, if Figure 1 As shown, the in-place detection device provided by the utility model also includes a positioning component, which includes a fixed tube 4 and a sleeve 5. The fixed tube 4 is a hollow structure, and the fixed tube 4 is sleeved outside the connecting rod 1, and one end of the fixed tube 4 is connected to the base plate 7; the sleeve 5 is arranged at one end of the fixed tube 4 close to the rolling component, and is sleeved on the connecting rod 1, and the connecting rod 1 can slide relative to the sleeve 5.

[0049] Since a part of the connecting rod 1 in the present application needs to be located in the coating cavity 15, the connecting rod 1 can be protected by arranging a fixing tube 4 outside the connecting rod 1 and arranging a sleeve 5 at the end of the fixing tube 4. Since the other end of the connecting rod 1 needs to pass through the substrate 7, that is, through the coating cavity 15, the sealing performance between the connecting rod 1 and the coating cavity 15 can be guaranteed to a certain extent by the fixing tube 4 and the sleeve 5.

[0050] It is understandable that if Figure 1 As shown, in the present application, one end of the fixed tube 4 away from the sleeve 5 is detachably connected to the base plate 7 by bolts, and a sealing ring 702 is provided between the base plate 7 and the bottom wall of the coating cavity 15, so as to seal the base plate 7 and the coating cavity 15. Accordingly, in the present application, the base plate 7 and the coating cavity 15 are detachably connected by bolts.

[0051] Alternatively, if Figure 1 As shown, a limiting portion 401 is formed in the fixing tube 4 in the present application at a position corresponding to the abutting portion 101 , and the limiting portion 401 and the accommodating groove 701 form a sliding space.

[0052] The limiting portion 401 formed in the fixed tube 4 can realize the clamping of the abutment portion 101, thereby avoiding to a certain extent the problem that the connecting rod 1 moves up too far under the action of the elastic member 8, causing the highest point that the rolling assembly can reach to exceed the bracket and cause the connecting rod 1 to be damaged.

[0053] Alternatively, if Figure 1 As shown, the positioning assembly in the present application further includes a dust cover 6 , which is disposed on the outside of the shaft sleeve 5 , and the connecting rod 1 passes through the dust cover 6 and can slide relative to the dust cover 6 .

[0054] The dust cover 6 can further protect the shaft sleeve 5, and to a certain extent prevent ions or dust precipitated in the coating cavity 15 from entering or adhering to the shaft sleeve 5, thereby ensuring the service life of the overall structure.

[0055] Alternatively, if Figure 1 As shown, the in-place detection device provided by the utility model also includes a push plate 10, which is connected to the end of the connecting rod 1 away from the coating cavity 15, the shielding member 11 is connected to the push plate 10, and a sealing sleeve 9 is connected between the substrate 7 and the push plate 10, and the end of the connecting rod 1 away from the rolling assembly passes through the substrate 7 into the sealing sleeve 9 and is connected to the push plate 10.

[0056] By providing the push plate 10 , the installation area of ​​the shielding assembly can be increased, making the connection of the shielding member 11 more stable.

[0057] However, since the connecting rod 1 needs to be able to slide relative to the base plate 7, a tight seal cannot be achieved. Therefore, the present application sets a sealing sleeve 9 between the push plate 10 and the base plate 7. A closed space can be formed by the push plate 10, the sealing sleeve 9, the base plate 7 and the above-mentioned sealing ring, the fixed tube 4 and the shaft sleeve 5, which can achieve both sealing and relative movement of the connecting rod 1.

[0058] It should be noted that the sealing sleeve 9 in the present application is a bellows. Since the push plate 10 moves up and down along the vertical direction following the connecting rod 1, the sealing sleeve 9 can be made into a bellows to achieve sealing between the push plate 10 and the base plate 7 and avoid affecting the movement of the push plate 10.

[0059] Specifically, Figure 1 As shown, the in-place detection device provided by the utility model also includes a guide assembly, which includes a guide rod 13, one end of which is connected to the base plate 7, and the other end is arranged through the push plate 10, the axis of the guide rod 13 is parallel to the axis of the connecting rod 1, and the push plate 10 can slide along the guide rod 13.

[0060] Since the push plate 10 is connected to the end of the connecting rod 1 and the length of the connecting rod 1 is relatively long, in order to prevent the connecting rod 1 from shaking during movement, the present application sets a guide assembly, and the guide assembly includes a guide rod 13, so that one end of the guide rod 13 is connected to the base plate 7, and the other end passes through the push plate 10, thereby providing assistance and guidance for the movement of the push plate 10, thereby ensuring the stability of the overall structure.

[0061] Alternatively, if Figure 1As shown, the guide assembly in the present application also includes a positioning plate 14, and the guide rod 13 passes through one end of the push plate 10 and is connected to the positioning plate 14. A accommodating cavity is formed on the positioning plate 14, and the photoelectric detection component 12 is arranged in the accommodating cavity. The shielding component 11 can follow the push plate 10 to reciprocate along the extension direction of the guide rod 13, and enter or leave the accommodating cavity to shield or expose the photoelectric detection component 12.

[0062] By connecting the guide rod 13 with the positioning plate 14 and the base plate 7 , the guide rod 13 can be positioned, and the installation stability of the guide rod 13 can be ensured, thereby ensuring the stability of the push plate 10 when sliding along the guide rod 13 .

[0063] Correspondingly, the accommodating cavity formed on the positioning plate 14 can also provide a stable installation position for the photoelectric detection element 12 .

[0064] In addition, the utility model also provides a continuous coating device, including multiple coating chambers 15, a hanger and the above-mentioned in-place detection device; the substrate 7 of the in-place detection device is connected to the bottom wall of the coating chamber 15, and the end of the connecting rod 1 away from the shielding member 11 is located in the coating chamber 15 and can contact the bottom of the hanger.

[0065] The continuous coating equipment using the in-place detection device provided in the present application can accurately detect the position of the hanger, and can improve the service life to a certain extent compared to the stop structure currently used, thereby ensuring the accuracy of the hanger in-place detection and improving the coating accuracy and coating effect.

[0066] It can be understood that the in-place detection device in the present application is arranged in a one-to-one correspondence with the coating cavity 15, that is, each coating cavity 15 is provided with an in-place detection device, so that the position of the hanger can be detected and positioned.

[0067] Preferably, the in-place detection device in the present application is located near the exit of the coating chamber 15. When the hanger enters the coating chamber 15, it continues to move toward the exit position. When the hanger contacts the in-place detection device, the connecting rod 1 is pressed down to make the covering member 11 cover the photoelectric detection member 12, thereby realizing in-place detection.

[0068] It should be noted here that the photoelectric detection element 12 in the present application is communicatively connected to the controller of the continuous coating equipment, and the photoelectric detection element 12 in the present application is always in the on state. When the shielding element 11 blocks the photoelectric detection element 12, the photoelectric detection element 12 is disconnected, so that the disconnection signal can be fed back to the controller, and then the controller can control the stop of the rack conveying equipment to realize the arrival detection and conveying stop of the rack.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
