Description

Technical Field

[0001] The invention relates to the technical field of suspension conveying, and more particularly to a suspension chain conveying assembly used for insulating varnish impregnation of electrical accessories. Background Art

[0002] In the process of electrical manufacturing, in order to improve the insulation performance and mechanical strength of electrical accessories, the electrical accessories need to be immersed in insulating varnish for treatment. After the immersion treatment, a uniform insulating varnish film is formed on the surface of the electrical accessories, which enhances their electrical insulation performance and environmental adaptability.

[0003] After searching, the patent number CN118412213A discloses "A Reactor Thermal Curing Machine", which drives the clamping part through the oil immersion tank, the drying part and the unloading conveyor in sequence through the conveyor belt, and sets a first adjustment part in the oil immersion tank, and sets a second adjustment part at the drying machine. During the immersion painting process, the first rack of the first adjustment part is driven by the gear on the clamping part to drive the clamping part and the product below it to rotate together. When the limit ring moves along the limit plate, it is restricted by the limit plate and cooperates with the first spring to drive the lower part of the connecting rod installation rod to move up and down;

[0004] But by the attached Figure 2 , 3 It can be seen that the limit plate is wavy, and the diameter of the limit ring is slightly larger than the width of the second fixed block. Since the second fixed block and the second spring need to rotate along the circumference and move horizontally, the second fixed block needs to be set away from the limit plate, resulting in a very small contact area between the limit ring and the limit plate. When the limit ring needs to move in a circular motion as well as up and down and horizontally, it is difficult to ensure stable contact between the limit ring and the wavy limit plate. The limit ring is a planar annular structure. How to ensure that the limit ring can move up and down along the end face of the wavy limit plate without getting stuck while performing circular rotation and horizontal linear motion? It is difficult to ensure that the entire clamping part can drive the product below to fluctuate stably up and down along the wavy limit ring. Moreover, a fixed structure is configured to clamp the reactor product, and the side in contact with the clamping part is difficult to be impregnated with paint, which has certain disadvantages. Summary of the invention

[0005] The purpose of the present invention is to solve the existing practical problems. Compared with the prior art, a hanging chain conveyor assembly for insulating varnish dipping of electrical accessories is provided. The gear on the hanging assembly cooperates with the bearing rack on the bearing rail to drive the electrical product to rotate. A guide seat with a guide rack is added above the varnish dipping tank, and a disc with a gear roller is added to the hanging assembly. When the hanging assembly is transmitted to the upper end of the varnish dipping tank, the gear roller is horizontally transmitted to the guide track and rolls along the end face of the guide rack to perform up and down undulating motion. Since the gear roller and the disc are rotatably installed, and the disc and the outer sleeve are telescopically installed, the disc can move up and down under the guidance of the gear roller without affecting the rotation of the disc, thereby realizing stable rotation and up and down movement of the electrical product during the dipping process. The electrical product is simply suspended by a hook, which is convenient for loading and unloading and allows the electrical product to continuously change the contact surface with the hook during the shaking process, thereby improving the dipping effect.

[0006] The object of the present invention can be achieved by the following technical scheme: a suspension chain conveyor assembly for insulating varnish dipping of electrical accessories, comprising a traction rail suspended and installed above a varnish dipping tank and in an annular closed structure, a plurality of conveying seats for conveying along the annular direction of the traction rail being installed on the bottom end surface of the traction rail through a plurality of connectors, and a suspension assembly being rotatably installed on the conveying seat;

[0007] The suspension assembly includes a rotating shaft rotatably mounted inside the conveying seat, the bottom end of the rotating shaft passes through the conveying seat and is fixedly connected to an outer sleeve, a disc that can move up and down is installed below the outer sleeve, a hook for hanging electrical accessories is installed at the bottom of the disc through a yoke, a bearing rail matching its structure is fixedly installed below the traction rail, and a bearing rack that matches the gear structure is provided at the lower edge of the bearing rail;

[0008] A guide seat corresponding to the position of the paint immersion pool is fixedly installed at the bottom end of the traction rail, a guide track is opened on the guide seat, a guide rack is provided on the bottom end wall of the guide track, and a gear roller adapted to the guide rack is rotatably installed in the circumferential direction of the disc.

[0009] Furthermore, the paint dipping pool is arranged corresponding to the horizontal section in front of the traction rail, and the end of the paint dipping pool is also connected to a drying box which is rotated and extended to the horizontal section behind the traction rail. The paint dipping pool and the drying box are arranged in the conveying direction of the conveying seat, and the electrical accessories suspended under the conveying seat are first dipped in the insulating paint in the paint dipping pool, and then conveyed to the drying box for drying. Compared with the conveyor belt distributed up and down, which can only allow the dipping and drying to be set on the same straight conveyor line of the conveyor belt, the dipping and drying of this scheme are connected before and after and distributed on the annular conveyor line of the traction rail, thereby shortening and extending the total length of the conveyor line.

[0010] Furthermore, the bearing rail is an annular structure adapted to the traction rail structure, and the starting end of the bearing rack is located on the upper side of the end of the guide seat, and the terminating end of the bearing rack is located on the upper side of the end of the drying box away from the paint dipping tank. During the dipping and drying process, the electrical products under the suspension assembly are driven to rotate, thereby improving the dipping and drying effects.

[0011] Furthermore, a telescopic tube is installed inside the outer sleeve and is connected to the rotating shaft and the disc respectively. The telescopic tube is a sleeve and a sleeve rod structure that is movably sleeved inside and outside. The sleeve is fixedly connected to the disc, and the top of the sleeve rod is fixed to the top of the outer sleeve. A tension spring is sleeved on the sleeve rod.

[0012] Furthermore, the guide track includes a horizontal section located at the front and rear ends and an inclined section connected to and docked with a pair of horizontal sections and arranged to be inclined downward, and a wavy section connected to each other is provided between the pair of inclined sections.

[0013] Furthermore, an annular sliding cavity is provided on the disc, and a swivel joint that is frictionally and rotatably matched with the annular sliding cavity is rotatably installed on the axis of the gear roller, and a swivel groove that fits and moves with the end face of the outer ring of the disc is provided at the end of the gear roller. The gear roller not only rotates along the circumference of the annular sliding cavity of the disc, but also rotates itself along its axial direction under the action of the swivel joint. When the suspension assembly is transmitted to the load-bearing rack, the gear roller is driven by the disc and just horizontally transmitted to the horizontal section of the guide track. The gear roller rolls along the end face of the guide rack, which limits the movement of the gear roller. The gear roller moves up and down along the end face of the guide rack, and the suspension assembly rotates along the forward direction under the cooperation of the traction rail and the load-bearing rack and the gear. At this time, due to the restriction of the movement of the disc by the gear roller, the disc can both rotate and move up and down under the action of the telescopic tube.

[0014] Furthermore, a reflow table tilted downward is fixedly connected to the inner top of the paint dipping pool close to the drying box, and a paint dipping layer laid at the bottom of the paint dipping pool is connected to the bottom of the reflow table, and the paint dipping layer is made of a porous adsorption structure.

[0015] Furthermore, a rotating ring is fixed to the top end of the hook, and the rotating ring is rotatably connected to the bottom end of the arm.

[0016] Furthermore, the end of the drying box away from the paint dipping pool is externally connected to a guide stripping rod that matches the hook position, and the guide stripping rod includes a horizontal portion adjacent to one end of the drying box, and the outer end of the horizontal portion is provided with an inclined portion inclined upward toward the traction rail. The horizontal portion can be connected to the end of the drying box through a connecting rod, or be externally connected to the end of the drying box through a connecting rod.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] (1) This scheme is to improve the existing hanging chain conveying structure used in the paint dipping work. The gear on the hanging assembly cooperates with the bearing rack on the bearing rail to drive the electrical product to rotate. A guide seat with a guide rack is added above the paint dipping tank, and a disk with a gear roller is added to the hanging assembly. The gear roller is matched with the guide rack. When the hanging assembly is transferred to the upper end of the paint dipping tank, the gear roller is horizontally transferred to the guide rail and rolls along the end surface of the guide rack to make an up and down movement. Since the gear roller and the disk are rotatably installed, and the disk and the outer sleeve are telescopically installed, the up and down movement of the guide rail is relied on without affecting the rotation of the disk. The electrical product under the disk is driven to move up and down, and the electrical product can rotate stably and move up and down during the dipping process. The hook structure is used to simply hang the electrical product, which is convenient for loading and unloading the electrical product, and the electrical product suspended on the hook, such as the inductor coil, constantly changes the contact surface with the hook during the shaking process, thereby achieving full dipping and improving the dipping effect.

[0019] (2) This scheme also sets the hook and the arm to rotate at a fixed point. The end of the drying box away from the paint immersion tank is also connected to a guide stripping rod that matches the position of the hook. The hook moved out of the drying box smoothly passes through the guide stripping rod. As the hook continues to move horizontally, the hook is pushed up in the opposite direction by the inclined part as the inclined part tends to tilt upward and inward, until the inductor coil at its upper end is detached downward, completing the automatic stripping of the inductor coil.

DETAILED DESCRIPTION

[0031] The following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0032] Example 1: The present invention discloses a suspension chain conveyor assembly for impregnation of insulating varnish for electrical accessories, see Figure 1 , including a traction rail 1 suspended and installed above a paint immersion pool 14 and in a ring-shaped closed structure. The traction rail 1 is a chain-type ring-shaped track structure. A plurality of conveying seats 2 for conveying along the ring direction of the traction rail 1 are installed on the bottom end surface of the traction rail 1 through a plurality of connectors. A suspension component is rotatably installed on the conveying seat 2. The electrical product is suspended by the suspension component. This solution is aimed at electrical products with holes or ring-shaped structures, such as inductors.

[0033] The paint dipping pool 14 is arranged corresponding to the horizontal section in front of the traction rail 1. The end of the paint dipping pool 14 is also connected to a drying box 15 which is rotated and extended to the horizontal section behind the traction rail 1. The paint dipping pool 14 and the drying box 15 are arranged in the conveying direction of the conveying seat 2. The electrical accessories suspended under the conveying seat 2 are first dipped in the insulating paint in the paint dipping pool 14, and then conveyed to the drying box 15 for drying. Compared with the conveyor belt distributed up and down, which can only allow the dipping and drying to be set on the same straight conveyor line of the conveyor belt, the dipping and drying of this scheme are connected before and after and distributed on the annular conveyor line of the traction rail 1, thereby shortening and extending the total length of the conveyor line.

[0034] Among them, see Figure 2-Figure 4The suspension assembly includes a rotating shaft 3 rotatably installed inside the conveying base 2. The bottom end of the rotating shaft 3 passes through the conveying base 2 and is fixedly connected to an outer sleeve 5. A disc 8 that can move up and down is installed below the outer sleeve 5. A hook 10 for hanging electrical accessories is installed at the bottom of the disc 8 through an arm 9. A bearing rail 7 matching its structure is fixedly installed below the traction rail 1. A bearing rack 701 matching the gear 4 structure is provided at the lower edge of the bearing rail 7.

[0035] The supporting rail 7 is an annular structure compatible with the traction rail 1 structure. The length of the supporting rack 701 can be set according to actual needs to ensure that the starting end of the supporting rack 701 is located on the upper side of the end of the guide seat 11, and the terminal end of the supporting rack 701 is located on the upper side of the end of the drying box 15 away from the paint immersion pool 14. The gear 4 on the suspension assembly cooperates with the supporting rack 701 on the supporting rail 7 to drive the electrical products on the hook 10 to rotate during the dipping and drying process, thereby improving the dipping and drying effects.

[0036] Embodiment 2: Based on Embodiment 1, this embodiment improves the structure of the suspension assembly and adds a guide seat 11 with a guide rack 12 above the paint immersion pool 14. The two cooperate with each other to achieve that the suspension assembly can rotate and move up and down stably when it is transferred to the paint immersion pool 14, as follows:

[0037] See also Figure 4-Figure 6 The outer sleeve 5 is internally provided with a telescopic tube 6 connected to the rotating shaft 3 and the disc 8 respectively. The telescopic tube 6 is a sleeve and a sleeve rod structure that is movably sleeved inside and outside. The sleeve is fixedly connected to the disc 8. The top of the sleeve rod is fixed to the top of the outer sleeve 5. A tension spring is sleeved on the sleeve rod. In the initial state, the telescopic tube 6 is in a contracted state by relying on the elasticity of the tension spring.

[0038] See also Figure 1-Figure 3 , Figure 7 A guide seat 11 corresponding to the position of the paint immersion pool 14 is fixedly installed at the bottom end of the traction rail 1, a guide track 111 is provided on the guide seat 11, a guide rack 12 is provided on the inner bottom end wall of the guide track 111, a gear roller 13 adapted to the guide rack 12 is rotatably installed in the circumferential direction of the disc 8, an annular sliding cavity 801 is provided on the disc 8, a swivel joint 131 adapted to frictionally rotate with the annular sliding cavity 801 is rotatably installed on the axis of the gear roller 13, and a swivel joint notch that fits and moves with the outer ring end face of the disc 8 is provided at the end of the gear roller 13, the gear roller 13 not only rotates along the circumference of the annular sliding cavity 801 of the disc 8, but also rotates along its axis direction under the action of the swivel joint 131;

[0039] The starting end of the load-bearing rack 701 is located on the upper side of the end of the guide seat 11, and the terminal end of the load-bearing rack 701 is located on the upper side of the end of the drying box 15 away from the paint immersion pool 14. The guide rail 111 includes horizontal sections at the head and tail ends and an inclined section connected and docked with a pair of horizontal sections and inclined downward, and a wavy section is provided between the pair of inclined sections.

[0040] See also Figure 7 , Figure 8 Before the suspension assembly is transferred to the load-bearing rack 701, the gear roller 13 can move synchronously with the disc 8. When the suspension assembly is transferred to the load-bearing rack 701, the gear roller 13 is driven by the disc 8 to be horizontally transferred to the horizontal section of the guide track 111. This process can be set to achieve that the gear roller 13 is in a state of being parallel to the horizontal section of the guide track 111 when entering the horizontal section of the guide track 111. The guide rack 12 on the horizontal section of the guide seat 11 rotates and drives the gear roller 13, that is, the gear roller 13 rolls along the end surface of the guide rack 12, which limits the movement of the gear roller 13, and the gear roller 13 moves up and down along the end surface of the guide rack 12;

[0041] The suspension assembly rotates in the forward direction under the cooperation of the traction rail 1 and the load-bearing rack 701 and the gear 4. At this time, due to the movement restriction of the disc 8 by the gear roller 13, the disc 8 can both rotate and move up and down along the wire track 111 under the action of the telescopic tube 6, that is, the electrical products conveyed to the paint immersion pool 14 are tilted downward from the end of the paint immersion pool 14 into the paint immersion pool 14. During the immersion process, by relying on the slow and uniform circular rotation and the coordination of the up and down movement, the electrical products such as the inductor coil suspended on the hook 10 continuously change the contact surface with the hook 10 during the shaking process, thereby achieving comprehensive immersion and improving the immersion effect. After continuous forward transmission, the electrical products are conveyed upward from the other end of the paint immersion pool 14 to the outside of the paint immersion pool 14, completing the entire immersion process.

[0042] In addition, it should be added that the top of the paint immersion pool 14 near the drying box 15 is fixedly connected to a downwardly inclined reflow platform 142, and the bottom of the reflow platform 142 is connected to a paint immersion layer 141 laid at the bottom of the paint immersion pool 14, and the paint immersion layer 141 is made of a porous adsorption structure;

[0043] When the gear roller 13 is transmitted to the bottom of the wave section, the telescopic tube 6 is forced to be stretched, so that the disc 8 drives the hook 10 below it to move downward until the electrical product on the hook 10 abuts against the varnish layer 141 and continues to press down. After the hook 10 abuts against the varnish layer 141, it is lifted upward by a proper distance. At this time, one end of the inductor of the electrical product that was originally connected to the hook 10 is temporarily separated from the hook 10, which is conducive to the inductor being temporarily suspended.

[0044] When the hook 10 is lifted again, the contact between the hook and the inductor coil is realized again, and the contact surface between the two is constantly changed, which is conducive to the complete immersion of each end surface of the inductor coil into the insulating paint. A layer of flexible material can be coated on the hook 10 according to actual needs, and ultrasonic vibration sheets are added on both sides of the lower end of the immersion pool 14 to further improve the immersion effect. Note that the opening at the top of the hook 10 is within a reasonable range to prevent electrical products such as the inductor coil from escaping from the opening at the top of the hook 10 during shaking;

[0045] While the electrical product is being transferred upward from the end of the paint immersion tank 14 to the outside of the paint immersion tank 14, it is still rotating. Therefore, after the electrical product is separated from the upper paint surface, it is easy to throw away the excess paint attached to the electrical product, and the excess paint flows back to the paint immersion tank 14 along the reflow table 142. On the one hand, it avoids that too much paint on the electrical product affects the painting effect after curing, and on the other hand, it prevents the excess paint from dripping into the subsequent drying box 15.

[0046] In order to realize automatic unloading of the inductive coil on the hook 10, the connection between the hook 10 and the arm 9 is improved, and a guide stripping rod 16 for upwardly pulling the hook 10 in the conveying direction is added at the end of the drying box 15, as follows:

[0047] See also Fig. 9 , Fig.10 A rotating ring 101 is fixed to the top of the hook 10, and the rotating ring 101 is rotatably connected to the bottom end of the arm 9. The end of the drying box 15 away from the paint immersion pool 14 is also externally connected to a guide stripping rod 16 that matches the position of the hook 10. The guide stripping rod 16 includes a horizontal portion 161 adjacent to one end of the drying box 15, and the outer end of the horizontal portion 161 is provided with an inclined portion 162 inclined upward toward the side of the traction rail 1. The horizontal portion 161 can be connected to the end of the drying box 15 through a connecting rod, or connected to the outside of the end of the drying box 15 through a connecting rod, so that the hook 10 that stops rotating can smoothly penetrate the guide stripping rod 16 after moving outside the drying box 15;

[0048] As the hook 10 continues to move forward horizontally, the hook 10 is reversely pushed up by the inclined portion 162 as the inclined portion 162 tilts upward and inward, until the inductor coil at its upper end is disengaged downward, completing the automatic removal of the inductor coil.

[0049] In summary, the invention is to improve the existing suspension chain conveying structure used in the paint dipping work, and realize the circumferential rotation of the suspension component by cooperating the gear 4 on the suspension component with the bearing rack 701 on the bearing rail 7, and by adding a guide seat 11 with a guide rack 12 above the paint dipping pool 14, and adding a disc 8 with a gear roller 13 on the suspension component, the gear roller 13 is adapted to the guide rack 12, when the suspension component drives the electrical product to be conveyed to the upper end of the paint dipping pool 14, the gear roller 13 is horizontally conveyed to the guide rail 111, and rolls along the end surface of the guide rack 12 to make an up and down movement;

[0050] Since the gear roller 13 and the disc 8 are rotatably installed, the electrical products under the disc 8 can be driven to move up and down without affecting the rotation of the disc 8, thereby achieving stable rotation and up and down movement of the electrical products during the impregnation process. The hook 10 structure is used to suspend and install the electrical products, which is convenient for loading and unloading the electrical products and allows the electrical products that are not fixedly installed and suspended on the hook 10, such as the inductor coil, to continuously change the contact surface with the hook 10 during the shaking process, thereby achieving comprehensive impregnation and improving the impregnation effect.

[0051] The above are only preferred specific implementation modes of the present invention; however, the protection scope of the present invention is not limited thereto; any technician familiar with the technical field within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved concept of the present invention shall be covered within the protection scope of the present invention.
