Description

Technical Field

[0001] This invention relates to the field of busbar trunking inspection technology, specifically to a busbar trunking automated inspection equipment and its inspection method. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbar columns, used to distribute large amounts of power to various components in a distributed system. Currently, it is increasingly replacing wires and cables in indoor low-voltage power transmission trunk line projects. During the production process of busbar trunking, insulation testing is required.

[0003] Existing busbar trunking testing devices can only perform insulation testing on busbar trunking of the same specification by fixing it in place and then automatically lowering the testing head and voltage sensor and inserting it into the corresponding copper busbar at the end of the busbar trunking. However, busbar trunking specifications vary, especially in length, which is produced in various lengths according to actual needs. This means that existing testing devices cannot meet the insulation testing requirements of busbar trunking of different specifications, resulting in low testing efficiency. In addition, impurities may remain in the busbar trunking during production. If these impurities are not removed before testing, the accuracy of the busbar trunking testing will inevitably be affected. Therefore, how to develop a automated, production line-type testing device for busbar trunking that can be used for automated testing of busbar trunking of different lengths has become an urgent problem to be solved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a busbar trunking assembly line type automatic testing equipment and testing method, which can realize the assembly line type automatic insulation testing of busbar trunking, and this process saves time and effort and improves testing efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The innovative feature of the busbar trunking assembly line automatic inspection device of the present invention is that it includes a gantry frame, a conveying mechanism I, a cleaning component, a conveying mechanism II, a detection head, and a voltage detector; the opening slot of the gantry frame is arranged horizontally, and its two opening ends are vertically downward mounted on the ground; conveying mechanisms I and II for busbar trunking transmission are also arranged horizontally and coplanarly at a lower position inside the gantry frame, and conveying mechanisms I and II extend vertically outward from the left and right sides of the gantry frame respectively; inside the gantry frame, relative to the conveying... A cleaning assembly is provided between mechanism I and conveying mechanism II, and the busbar troughs transferred from conveying mechanism I to conveying mechanism II are cleaned by the cleaning assembly. Inside the gantry frame, a detection head and a voltage detector are arranged horizontally and collinearly at intervals on the left and right sides, directly above conveying mechanism II. The voltage detector is inserted into the copper busbar at the right end of the busbar trough one by one by vertical up and down and horizontal longitudinal movement. The detection head first adapts to the length of the busbar trough by horizontal lateral movement, and then inserts into the copper busbar at the left end of the busbar trough by vertical up and down movement. The insulation of the busbar trough is then tested by the cooperation of the detection head and the voltage detector.

[0006] It also includes a first baffle, a second baffle, and a lifting assembly; a first baffle is vertically arranged on the left side inside the portal frame, and the first baffle is spaced between corresponding adjacent conveying rollers of the conveying mechanism I; a second baffle is also vertically arranged inside the portal frame directly below the voltage detector, and the second baffle is spaced between corresponding adjacent conveying rollers of the conveying mechanism II; the first baffle and the second baffle are parallel and aligned horizontally, and a lifting assembly is vertically arranged on their lower surfaces, which drives the corresponding first baffle or second baffle. The baffle moves vertically up and down, thereby limiting the busbar trough on conveying mechanism I to the right through the first baffle and the busbar trough on conveying mechanism II to the right through the second baffle. When the vertical up and down stroke of the first baffle and the second baffle is at the upper limit position, the upper ends of the first baffle and the second baffle exceed the conveying roller surface of conveying mechanism I and limit the busbar trough transmitted on conveying mechanism I or conveying mechanism II respectively. At the same time, when the first baffle and the second baffle are at the lower limit position, they do not interfere with the transmission of the busbar trough on conveying mechanism I or conveying mechanism II.

[0007] The cleaning assembly includes partition I, partition II, a fan, a main air duct, branch air ducts, and an air outlet. Inside the portal frame, partitions I are symmetrically arranged horizontally and vertically between conveying mechanisms I and II, with two partitions I spaced apart on the upper and lower sides of the busbar trough. Their front and rear ends are fixedly connected to the corresponding positions of the front and rear inner surfaces of the portal frame, and do not affect the transmission action of conveying mechanism I or conveying mechanism II. Between the two partitions I, a partition II is vertically and horizontally arranged relative to the rear side of conveying mechanism I and relative to the interior of the portal frame. The left and right ends of partition II are aligned with the left and right ends of the corresponding partition I, and their upper and lower ends are vertically and fixedly connected to the inner surface of the corresponding partition I. A hollow rectangular branch air duct is vertically and horizontally parallel to the front side of partition II relative to the rear side of the busbar trough, with the left and right ends of the branch air duct aligned with the left and right ends of partition II. Furthermore, its upper and lower ends extend vertically to the corresponding positions of partition I, and then extend horizontally towards the front, forming a U-shape to partially cover the section of the busbar trough located between conveying mechanism I and conveying mechanism II. The branch ducts are fixedly connected to the front surface of partition II and the inner surface of partition I via fixing rods. A fan is also installed in the middle of the rear surface of partition II relative to the portal frame. The fan is connected to the branch ducts via the main duct through partition II. Several air outlets are evenly distributed and sealed on the upper inner surface, front inner surface, and lower inner surface of the branch ducts. Each air outlet is set towards the busbar trough located between conveying mechanism I and conveying mechanism II. The fan continuously blows air onto the surface of the busbar trough through the main duct, branch ducts, and air outlets in sequence, thereby removing residual debris from the surface of the busbar trough and ensuring that the movement of the busbar trough from conveying mechanism I to conveying mechanism II does not interfere with the movement of the busbar trough.

[0008] Preferably, the left end of the conveying mechanism I extends horizontally to the left of the gantry frame, and the right end of the conveying mechanism II extends horizontally to the right of the gantry frame. The distance between the conveying mechanism I and the conveying mechanism II must ensure that the busbar can be smoothly transferred from the conveying mechanism I to the conveying mechanism II. The cleaning component does not interfere with the transmission actions of the conveying mechanism I and the conveying mechanism II, and ensures that the internal longitudinal width of the gantry frame is greater than the longitudinal width of the conveying mechanism I. Thus, through the cooperation of the conveying mechanism I and the conveying mechanism II, the busbar is transferred into the gantry frame for cleaning before insulation testing.

[0009] Preferably, each of the lifting components includes a housing, a lead screw, a main bevel gear, a driven bevel gear, a second motor, a sleeve, a slide rod, a fourth slide rail, a third lifting plate, and a second reinforcing plate; housings are vertically arranged on the ground directly below the first and second baffles and relative to the interior of the gantry frame, each housing being a hollow cuboid structure, and are respectively spaced apart directly below conveying mechanism I or conveying mechanism II; a clearance hole is embedded in the middle of the upper surface of each housing, and each clearance hole communicates with the interior of the corresponding housing; a lead screw is vertically and coaxially arranged in the middle of the interior of each housing, and the diameter of each lead screw is smaller than the diameter of the corresponding clearance hole, with the lower end of each lead screw...

Driven by the second motor, the third lifting plate is driven to move vertically up and down through the meshing of the main bevel gear and the driven bevel gear. The lower surfaces of the first baffle and the second baffle are fixedly arranged in the middle of the upper surface of the corresponding third lifting plate. A second reinforcing plate is vertically arranged between the left and right sides of the first baffle and the upper surface of the corresponding third lifting plate.

[0011] On the left and right sides of each sleeve, a fourth slide rail is vertically and symmetrically spaced relative to the interior of the corresponding housing, and each fourth slide rail is fixedly connected to the inner side of the corresponding housing. A horizontal slide rod is also provided between the left and right outer sides of each sleeve and the corresponding fourth slide rail. One end of each slide rod is fixedly connected to the corresponding outer side of the sleeve, and the other end is matched with the corresponding fourth slide rail. The cooperation of the slide rod and the fourth slide rail ensures the stability of the sleeve's vertical up-and-down movement. A first rubber pad is vertically and fixedly attached to the upper part of the left side of the first and second baffles. When the first or second baffle is in a limiting position, the first rubber pad protects the busbar groove and ensures that the first rubber pad does not affect the rotation of the conveying rollers of conveying mechanism I or conveying mechanism II.

[0012] Preferably, the cleaning assembly further includes a collection hood, a dust removal device, and a filter screen; several ventilation holes are vertically embedded and penetrated in a matrix at evenly spaced intervals on the rear outer surface of the portal frame relative to the position of partition II, and a filter screen is vertically and horizontally fixed on the rear inner surface of the portal frame relative to the position of the ventilation holes, ensuring that the filter screen covers all the ventilation holes; a funnel-shaped collection hood is vertically provided on the front inner surface of the portal frame relative to the position of partition II, with the large-diameter end of the collection hood facing the rearward direction, and does not affect the transmission action of conveying mechanism I or conveying mechanism II respectively; the small-diameter end of the collection hood extends vertically out of the front outer surface of the portal frame and is sealed and connected to the dust removal device installed at the corresponding position on the front outer surface of the portal frame, thereby collecting the removed residual debris through the dust removal device and the collection hood.

[0013] Preferably, it further includes a first electric push rod, a first lifting plate, a first slide rail, and a first slider; inside the gantry frame, on the right side, directly above the conveying mechanism II, a first lifting plate matching the interior of the gantry frame is horizontally arranged, and on its upper surface, symmetrically arranged vertically at intervals relative to the first lifting plate, are first electric push rods. The pushing ends of the two first electric push rods move synchronously, and their pushing ends extend vertically downward into the interior of the gantry frame, respectively, and are screwed and fixed to the corresponding positions on the upper surface of the first lifting plate, thereby driving the first lifting plate to move vertically up and down inside the gantry frame relative to the area above the conveying mechanism II; on the front and rear inner surfaces of the gantry frame, symmetrically arranged vertically at intervals relative to the first lifting plate, are two first slide rails, and on the front and rear end faces of the first lifting plate, corresponding to the positions of the first slide rails, are first sliders matching the first slide rails, thereby ensuring the stability of the vertical up and down movement of the first lifting plate through the cooperation of the first slide rails and the first sliders.

[0014] Preferably, it further includes side plates, a first motor, threaded rods, guide rails, moving blocks, and connecting plates; vertically arranged side plates are symmetrically spaced on the lower surface of the first lifting plate, with the right side plate positioned near the second baffle; two horizontally arranged threaded rods are symmetrically spaced in the middle between the two side plates, the right end of each threaded rod being rotatably connected to the right side plate, and its left end extending horizontally and vertically out of the left side plate, and respectively linked to the output end of the corresponding first motor; the two first motors are horizontally spaced in the middle, their movements are synchronized, and they are respectively screwed and fixed to the left side plate; horizontally spaced on the upper and lower sides of each threaded rod... The frame is symmetrically equipped with guide rails, each of which is located within a square area enclosed by two side plates, and its left and right ends are screwed and fixed to the corresponding side plates respectively. Two movable blocks are also sleeved on each threaded rod at intervals, and the four movable blocks are arranged in a rectangular pattern. Each movable block is screwed to its corresponding threaded rod and horizontally slidably connected to its corresponding two guide rails, ensuring that the lower surfaces of the four movable blocks are on the same horizontal plane. A connecting plate is horizontally positioned inside the portal frame directly below the movable blocks, and its upper surface is fixedly connected to the lower surfaces of the four movable blocks. Driven by the first motor, the connecting plate reciprocates horizontally with the movable blocks and moves vertically up and down with the first lifting plate.

[0015] Preferably, it further includes a fixed plate, a first reinforcing plate, a fourth electric push rod, a second lifting plate, a third slide rail, a third slider, an L-shaped plate, and a fifth electric push rod; a fixed plate is also horizontally and longitudinally arranged at a position slightly below the right side surface of the right-side side plate, and the lower surface of the fixed plate is horizontally and coplanarly arranged with the lower surface of the right-side side plate; a first reinforcing plate is also vertically arranged between the upper surface of the fixed plate and the right side surface of the right-side side plate, and the fixed plate is fixed and reinforced by the first reinforcing plate; a second lifting plate is also horizontally and longitudinally arranged between the fixed plate and the conveying mechanism II on the side of the fixed plate, and a fourth electric push rod is also vertically and symmetrically arranged at intervals on the upper surface of the fixed plate, the two fourth electric push rods move synchronously, and are respectively arranged at intervals on the right side of the first reinforcing plate; the pushing end of each fourth electric push rod extends vertically downward from the lower surface of the fixed plate, and is screwed and fixed to the corresponding position of the upper surface of the second lifting plate, and drives the second lifting plate to move vertically up and down in the area directly above the conveying mechanism II;

[0016] The voltage detectors are spaced apart and positioned directly above the copper busbar at the right end of the busbar trough after being stopped by the second baffle. Their detection ends are vertically downwards. The L-shaped plate is positioned on the lower surface of the second lifting plate relative to the voltage detectors, with its horizontal side facing forward and its vertical side facing downwards. The fixed end of the voltage detector is mounted on the lower surface of the horizontal side of the L-shaped plate, and its detection end extends vertically downwards beyond the horizontal plane of the end of the vertical side of the L-shaped plate, ensuring that the L-shaped plate is aligned with the copper busbar at the right end of the busbar trough where the voltage detector is inserted. The movement does not cause interference; a fifth electric push rod is also provided horizontally and longitudinally on the rear side of the L-shaped plate. The tail of the fifth electric push rod is fixedly connected to the corresponding position of the lower surface of the second lifting plate through a fixed rod, and its pushing end is set in the forward direction and screwed to the outer surface of the vertical side of the L-shaped plate. Then, the fifth electric push rod drives the voltage detector to move horizontally and longitudinally within the coverage area of ​​the copper busbar at the right end of the busbar trough, and the fourth electric push rod drives the voltage detector to move vertically up and down, and inserts it into the copper busbar at the right end of the busbar trough one by one.

[0017] On the lower surface of the second lifting plate, a third slide rail is provided horizontally and longitudinally at intervals relative to the horizontal longitudinal movement trajectory area of ​​the L-shaped plate. On the upper surface of the horizontal edge of the L-shaped plate, a third slider matching the third slide rail is provided relative to each third slide rail position. The stability of the horizontal longitudinal movement of the L-shaped plate is ensured through the cooperation of the third slide rail and the third slider.

[0018] Preferably, it further includes a second electric push rod and a T-shaped plate; a second electric push rod is vertically arranged on the left side of the square area enclosed by the four moving blocks on the upper surface of the connecting plate, and the second electric push rod is spaced between two threaded rods and is located near the left side of the moving block; the T-shaped plate is located on the lower surface of the connecting plate near the detection head, with its horizontal side on the upper side and its vertical side vertically downward; the fixed end of the detection head is screwed onto the right side of the vertical side of the T-shaped plate, and its detection end faces horizontally to the right. The second electric push rod is set up and ensured to be in the same vertical and horizontal plane as the busbar trough on the conveying mechanism II; the pushing end of the second electric push rod extends vertically downward from the lower surface of the connecting plate and is screwed to the upper surface of the horizontal side of the T-shaped plate, and drives the T-shaped plate to move vertically up and down in the area above the conveying mechanism II. Then, after the T-shaped plate moves horizontally with the connecting plate to the left end of the busbar trough connected to the copper busbar after being limited by the second baffle, the detection end of the detection head is inserted vertically downward into the left end of the busbar trough connected to the copper busbar by the second electric push rod.

[0019] Preferably, it further includes a third electric push rod, an adjusting plate, a second slide rail, a second slider, and a second rubber pad; on the lower surface of the connecting plate, four horizontally longitudinally arranged third electric push rods are symmetrically arranged in a rectangle relative to the right side of the T-shaped plate. The pushing ends of the four third electric push rods move synchronously, and their tails are fixedly connected to the corresponding positions on the lower surface of the connecting plate through fixing rods. The pushing ends of every two front and rear third electric push rods are arranged in a straight line facing each other, and the pushing ends of the two third electric push rods arranged on the same horizontal side are screwed and fixed to the upper end of the corresponding outer side of the vertically horizontally arranged adjusting plate, ensuring that the two adjusting plates are arranged parallel and spaced on the front and rear sides of the busbar groove, so that the third electric push rods push the corresponding adjusting plates to perform horizontal longitudinal reciprocating motion, and move vertically up and down and horizontally with the connecting plate; on the lower surface of the connecting plate, horizontally longitudinally arranged second slide rails are symmetrically arranged at left and right intervals between the two adjusting plates, and the upper end face of each adjusting plate is positioned relative to each second slide rail. Each adjustment plate is also equipped with a second slider that matches the second slide rail. The cooperation between the second slider and the second slide rail ensures the stability of the horizontal longitudinal movement of the corresponding adjustment plate. The lower end of each adjustment plate is vertically downward, and its lateral length is less than the length of the busbar. They are spaced apart on the right side of the detection head. The busbar is then corrected by the two adjustment plates moving in opposite directions along the horizontal longitudinal direction to ensure that the busbar is horizontally collinear with the detection head and the voltage detector. A second rubber pad is also fixedly attached to the lower end of the inner side of each adjustment plate to protect the busbar during the correction process. The upper limit position of the first lifting plate must ensure that the detection head, adjustment plate, and voltage detector do not interfere with the transmission of the busbar through the conveying mechanism II. Its lower limit position must ensure that the adjustment plate can correct the busbar and is spaced apart directly above the conveying mechanism II. It must also ensure that the detection head and voltage detector are directly above the corresponding end copper busbars of the busbar.

[0020] The innovation of the present invention lies in the following steps in a busbar trunking automated inspection device:

[0021] Step 1: First, select the appropriate detection head and voltage detector according to the specifications of the busbar trunking, and screw the fixed end of the detection head onto the right side of the vertical side of the T-shaped plate to ensure that it is in the same vertical and horizontal plane as the busbar trunking. Then, install the fixed end of the voltage detector on the lower surface of the horizontal side of the L-shaped plate.

[0022] Step 2: Then the busbar trunking is transferred to the gantry frame via the conveying mechanism I. After it is completely transferred to the right side of the first baffle, the first baffle is raised to the highest position by the lifting assembly, and the right limit is applied to the next busbar trunking.

[0023] Step 3: Then the busbar is transferred from conveying mechanism I to conveying mechanism II. During the process of passing through the cleaning components, the fan continuously blows air onto the surface of the busbar through the main air duct, branch air duct and air outlet in sequence to remove the residual debris on the surface of the busbar. The residual debris is then collected by the dust removal device through the collection hood.

[0024] Step 4: Then the second baffle rises to the highest position through the corresponding lifting component to limit the forward movement of the cleaned busbar and ensure that the copper busbar at the right end of the busbar is directly below the voltage detector.

[0025] Step 5: Then, according to the length of the busbar, under the drive of the first motor, the detection head and the adjustment plate are adjusted horizontally and laterally in sync with the connecting plate until the detection head is exactly above the copper busbar at the left end of the busbar after being limited by the second baffle.

[0026] Step Six: Then, driven by the first electric push rod, the first lifting plate descends to the lower limit position. At this time, the detection head and voltage detector descend vertically to the corresponding end copper busbar position near the busbar. Then, driven by the third electric push rod, the two adjusting plates move towards each other in the horizontal longitudinal direction to correct the position of the busbar, so as to ensure that the busbar is set in a straight line with the detection head and voltage detector in the horizontal direction.

[0027] Step 7: Then, driven by the second electric push rod, the detection end of the detection head is inserted vertically downward into the left end of the busbar trunking. Then, through the cooperation of the fourth and fifth electric push rods, the voltage detector is inserted into the right end of the busbar trunking one by one through vertical up and down and horizontal longitudinal movement. At this time, the insulation of the busbar trunking can be tested through the cooperation of the detection head and the voltage detector.

[0028] Step 8: After the test is completed, the second baffle descends to the lowest position. At this time, the tested busbar is transferred to the gate frame by the conveying mechanism II. At the same time, the first baffle descends to the lowest position. Then, the above steps are repeated to clean the next busbar in turn and then perform insulation test.

[0029] The beneficial effects of this invention are:

[0030] (1) The present invention can realize the automatic insulation detection of busbar trunking in a production line manner, and this process saves time and effort and improves detection efficiency;

[0031] (2) The present invention first positions the busbar trough transmitted by the conveying mechanism II through the second baffle, and then adjusts the horizontal position of the detection head according to the length of the busbar trough by the cooperation of the first motor, threaded rod, guide rail, moving block and connecting plate, so as to facilitate the insulation detection of busbar troughs of different lengths. This process not only saves time and effort, but also saves equipment costs and has a wide range of applications.

[0032] (3) The present invention facilitates the front and rear positioning of the cleaned busbar by using the third electric push rod, the adjusting plate, the second slide rail and the second slider in combination, so as to prevent the busbar from deviating due to air blowing cleaning, thereby ensuring that the detection head and voltage detector can be lowered and accurately inserted into the corresponding end copper busbar of the busbar, ensuring the smooth progress of the detection operation and improving the detection efficiency.

[0033] (4) The third electric push rod and the adjusting plate of the present invention can move horizontally and laterally synchronously with the connecting plate, thereby enabling position correction of busbars of different lengths and having a wide range of applications;

[0034] (5) The present invention facilitates the forward limit of the subsequent busbar on the conveying mechanism I by the cooperation of the first baffle and the corresponding lifting component, thereby ensuring that the busbar can carry out the assembly line inspection operation in an orderly manner;

[0035] (6) The present invention facilitates the forward limit of the cleaned busbar trough by the cooperation of the second baffle and the corresponding lifting component, thereby ensuring that the copper busbar at the right end of the busbar trough is located directly below the voltage detector. Based on this, the horizontal position of the detection head can be adjusted according to the length of the busbar trough, ensuring the smooth progress of the detection operation and improving the detection efficiency.

Detailed Implementation

[0047] The technical solution of the present invention will be clearly and completely described below through specific embodiments.

[0048] The present invention provides an automated inspection device for busbar trunking assembly lines, comprising a gantry frame 1, a conveying mechanism I 2, a cleaning assembly, a conveying mechanism II 4, an inspection head 30, and a voltage detector 43; as shown Figures 1-9As shown, the opening slot of the portal frame 1 is arranged horizontally, and its two opening ends are vertically downward and installed on the ground; inside the lower part of the portal frame 1, there are also horizontally spaced, coplanar conveying mechanisms I2 and II4 for busbar duct 3 transmission, and conveying mechanisms I2 and II4 extend vertically to the left and right sides of the portal frame 1 respectively; inside the portal frame 1, between the conveying mechanisms I2 and II4, there is a cleaning assembly, and the cleaning assembly cleans the busbar duct 3 transmitted from the conveying mechanism I2 to the conveying mechanism II4. The trough 3 is cleaned. Inside the gantry frame 1, above the conveying mechanism II 4, a detection head 30 and a voltage detector 43 are arranged horizontally and laterally at intervals. The voltage detector 43 is inserted into the copper busbar at the right end of the busbar trough 3 one by one through vertical up-down and horizontal longitudinal movements. The detection head 30 first adapts to the length of the busbar trough 3 through horizontal lateral movement, and then inserts into the copper busbar at the left end of the busbar trough 3 through vertical up-down movement. The insulation of the busbar trough 3 is then tested through the cooperation of the detection head 30 and the voltage detector 43. The conveying mechanism I 2 and the conveying mechanism II 4 of this invention are common roller conveyor devices, which are existing technologies and will not be described in detail here. In addition, the insulation test of the busbar trough 3 through the cooperation of the detection head 30 and the voltage detector 43 is a conventional existing testing method, and its testing principle will not be described in detail here.

[0049] like Figures 1-9 As shown, the left end of conveying mechanism I2 extends horizontally to the left side of portal frame 1, and the right end of conveying mechanism II4 extends horizontally to the right side of portal frame 1. The distance between conveying mechanism I2 and conveying mechanism II4 must ensure that busbar trough 3 can be smoothly transferred from conveying mechanism I2 to conveying mechanism II4. The cleaning components do not interfere with the transmission actions of conveying mechanism I2 and conveying mechanism II4, and ensure that the internal longitudinal width of portal frame 1 is greater than the longitudinal width of conveying mechanism I2. Then, through the cooperation of conveying mechanism I2 and conveying mechanism II4, busbar trough 3 is transferred into portal frame 1 for cleaning before insulation testing.

[0050] In this invention, a first baffle 5 is vertically arranged on the left side inside the portal frame 1, and the first baffle 5 is spaced apart between corresponding adjacent conveying rollers of the conveying mechanism I2; for example Figure 1 , Figure 5 , Figure 6As shown, a second baffle 6 is vertically arranged inside the gantry frame 1, directly below the voltage detector 43, and the second baffle 6 is spaced between the corresponding adjacent conveying rollers of the conveying mechanism II 4; the first baffle 5 and the second baffle 6 are arranged parallel and aligned with each other at a distance, and lifting components 9 are vertically arranged on their lower surfaces respectively. The lifting components 9 drive the corresponding first baffle 5 or second baffle 6 to move vertically up and down, thereby limiting the busbar trough 3 on the conveying mechanism I 2 to the right by the first baffle 5, and limiting the busbar trough 3 on the conveying mechanism II 4 to the right by the second baffle 6; wherein, when the vertical up and down movement of the first baffle 5 and the second baffle 6 is at the upper limit position, the upper ends of the first baffle 5 and the second baffle 6 exceed the surface of the conveying roller of the conveying mechanism I 2, and limit the busbar trough 3 transmitted on the conveying mechanism I 2 or the conveying mechanism II 4 respectively. At the same time, when the lower limit position is reached, the first baffle 5 and the second baffle 6 do not interfere with the transmission of the busbar trough 3 on the conveying mechanism I 2 or the conveying mechanism II 4. The present invention may provide a sensor on the inner top surface of the portal frame 1 relative to the position of the first baffle 5, for determining whether the previous busbar 3 has been completely transmitted to the right side of the first baffle 5, and after the previous busbar 3 has been completely transmitted to the right side of the first baffle 5, the first baffle 5 shall limit the next busbar 3 to the right. This is the prior art, so it will not be described in detail here.

The output end of each second motor 905 extends vertically toward the direction of the driven bevel gear 904 into the interior of the corresponding housing 901 and is connected to the driven bevel gear 904 through the meshing of the main bevel gear 903, thereby driving the lead screw 902 to rotate around its own axis.

[0052] like Figure 1 , Figure 5 , Figure 6 As shown, a sleeve 906 matching the clearance hole is coaxially sleeved at the upper end of each lead screw 902. Each sleeve 906 is screwed to the corresponding lead screw 902, and its upper end extends vertically upward through the clearance hole to the upper surface of the corresponding housing 901, and is screwed and fixed to the lower surface of the corresponding horizontally set third lifting plate 909. Then, driven by the second motor 905, the third lifting plate 909 is driven to move vertically up and down through the meshing of the main bevel gear 903 and the driven bevel gear 904. The lower surfaces of the first baffle 5 and the second baffle 6 are fixedly set at the middle position of the upper surface of the corresponding third lifting plate 909, and a second reinforcing plate 910 is vertically set between its left and right sides and the upper surface of the corresponding third lifting plate 909. The second reinforcing plate 910 fixes and reinforces the first baffle 5 or the second baffle 6 respectively, so that the first baffle 5 and the second baffle 6 move vertically up and down with the corresponding third lifting plate 909.

[0053] like Figure 1 , Figure 5 , Figure 6As shown, on the left and right sides of each sleeve 906, a fourth slide rail 908 is vertically and symmetrically spaced relative to the interior of the corresponding housing 901, and each fourth slide rail 908 is fixedly connected to the inner side of the corresponding housing 901. A slide rod 907 is horizontally arranged between the left and right outer sides of each sleeve 906 and the corresponding fourth slide rail 908. One end of each slide rod 907 is fixedly connected to the corresponding outer side of the corresponding sleeve 906, and the other end is matched with the corresponding fourth slide rail 908. The cooperation of the slide rod 907 and the fourth slide rail 908 ensures the stability of the vertical up-and-down movement of the sleeve 906. A first rubber pad is vertically and fixedly attached to the upper part of the left side of the first baffle 5 and the second baffle 6. When the first baffle 5 or the second baffle 6 is in a limiting position, the first rubber pad protects the busbar 3 and ensures that the first rubber pad does not affect the rotation of the conveying rollers of the conveying mechanism I2 or the conveying mechanism II4.

Two partitions 17 are spaced apart on the upper and lower sides of the busbar trough 3, and their front and rear ends are fixedly connected to the corresponding positions of the front and rear inner surfaces of the portal frame 1, respectively, without affecting the transmission action of the conveying mechanisms I2 or II4. Between the two partitions 17, a vertically horizontal partition 28 is provided relative to the rear side of the conveying mechanism I2 and the interior of the portal frame 1. The left and right ends of partition 28 are aligned with the left and right ends of the corresponding partitions 17, and their upper and lower ends are vertically fixedly connected to the inner surfaces of the corresponding partitions 17. A hollow rectangular branch duct 12 is provided vertically and horizontally parallel to the front side of partition 28 relative to the rear side of the busbar trough 3. The left and right ends of branch duct 12 are aligned with the left and right ends of partition 28, respectively, and their upper and lower ends extend vertically to the positions of the corresponding partitions 17. Then, they extend horizontally forward and in a U-shape to partially cover the section of the busbar trough 3 located between conveying mechanism I2 and conveying mechanism II4; the branch duct 12 is fixedly connected to the front surface of partition II8 and the inner surface of the corresponding partition I7 by fixing rods, and a fan 10 is also installed in the middle of the rear surface of partition II8 relative to the portal frame 1. The fan 10 is sealed and connected to the branch duct 12 through the main duct 11 and partition II8, and the upper inner part of the branch duct 12 is... The surface, front inner surface and lower inner surface are also provided with several air outlets 13 evenly spaced and sealed. Each air outlet 13 is arranged in the direction of the busbar trough 3 located between the conveying mechanism I2 and the conveying mechanism II4. The fan 10 continuously blows air onto the surface of the busbar trough 3 through the main air pipe 11, the branch air pipe 12 and the air outlet 13 in sequence, thereby removing residual debris from the surface of the busbar trough 3 and ensuring that the movement of the busbar trough 3 from the conveying mechanism I2 to the conveying mechanism II4 does not interfere with it.

[0055] like Figure 1 , Figure 2 , Figure 6 As shown, several ventilation holes 17 are vertically embedded and interspersed in a matrix at evenly spaced intervals on the rear outer surface of the portal frame 1 relative to the position of the partition II 8. A filter screen 16 is also vertically and horizontally fixed on the rear inner surface of the portal frame 1 relative to the position of the ventilation holes 17, ensuring that the filter screen 16 covers all the ventilation holes 17. A funnel-shaped collection cover 14 is also vertically provided on the front inner surface of the portal frame 1 relative to the position of the partition II 8. The large diameter end of the collection cover 14 is set in the rear direction and does not affect the transmission action of the conveying mechanism I 2 or the conveying mechanism II 4. The small diameter end of the collection cover 14 extends vertically to the front outer surface of the portal frame 1 and is sealed and connected to the dust removal device 15 installed at the corresponding position on the front outer surface of the portal frame 1. The dust removal device 15 collects the removed residual debris through the collection cover 14.

[0056] In this invention, a first lifting plate 19, matching the interior of the gantry frame 1, is horizontally arranged on the right side relative to the position directly above the conveying mechanism II 4. Furthermore, first electric push rods 18 are vertically symmetrically arranged on the upper surface of the first lifting plate 19 at left and right intervals. Figures 1-9 As shown, the pushing ends of the two first electric push rods 18 move synchronously, and their pushing ends extend vertically downwards into the interior of the gantry frame 1, respectively, and are screwed and fixed to the corresponding positions on the upper surface of the first lifting plate 19. This causes the first lifting plate 19 to move vertically up and down inside the gantry frame 1 relative to the area above the conveying mechanism II 4. Two first slide rails 20 are also vertically symmetrically arranged on the front and rear inner surfaces of the gantry frame 1, respectively, at left and right intervals relative to the positions of the first lifting plate 19. Furthermore, first sliders 21, matching the first slide rails 20, are respectively provided on the front and rear end faces of the first lifting plate 19 relative to the positions of the corresponding first slide rails 20. The stable vertical movement of the first lifting plate 19 is ensured through the coordinated use of the first slide rails 20 and the first sliders 21. This invention can synchronize the movements of the two first electric push rods 18 through controller control; this is prior art, and its principle will not be elaborated here.

[0057] The present invention further includes vertically arranged side plates 22 symmetrically spaced on the lower surface of the first lifting plate 19, with the right side plate 22 positioned near the second baffle 6. Additionally, two horizontally arranged threaded rods 23 are symmetrically spaced between the two side plates 22. Figures 1-9As shown, the right end of each threaded rod 23 is rotatably connected to the right side plate 22, and its left end extends horizontally and vertically out of the left side plate 22, and is linked to the output end of the corresponding first motor 27; the two first motors 27 are horizontally spaced apart and move synchronously, and are screwed and fixed to the left side plate 22 respectively; on the upper and lower sides of each threaded rod 23, there are horizontally spaced parallel and symmetrical guide rails 24, each guide rail 24 is set in the square area enclosed by the two side plates 22, and its left and right ends are screwed and fixed to the corresponding side plate 22 respectively; on each threaded rod 23 Two movable blocks 25 are also provided on the left and right sides at intervals, and the four movable blocks 25 are distributed in a rectangular shape. Each movable block 25 is screwed to a corresponding threaded rod 23 and is horizontally slidably connected to two corresponding guide rails 24, ensuring that the lower surfaces of the four movable blocks 25 are in the same horizontal plane. A connecting plate 26 is horizontally positioned inside the portal frame 1 directly below the movable blocks 25, and its upper surface is fixedly connected to the lower surfaces of the four movable blocks 25. Driven by the first motor 27, the connecting plate 26 moves horizontally and reciprocally with the movable blocks 25, and moves vertically up and down with the first lifting plate 19. The present invention can synchronize the actions of the two first motors 27 through the control of the controller. This is prior art, so its principle will not be described in detail here.

[0058] The present invention further includes a horizontally longitudinally fixed plate 35 located slightly below the right side surface of the right side plate 22, and the lower surface of the fixed plate 35 is horizontally coplanar with the lower surface of the right side plate 22; for example Figures 1-9 As shown, a first reinforcing plate 36 is vertically arranged between the upper surface of the fixed plate 35 and the right side of the right side plate 22, and the fixed plate 35 is fixed and reinforced by the first reinforcing plate 36; a second lifting plate 38 is horizontally and longitudinally arranged between the fixed plate 35 and the conveying mechanism II 4 on the side of the fixed plate 35, and a fourth electric push rod 37 is vertically and symmetrically arranged at intervals on the upper surface of the fixed plate 35. The two fourth electric push rods 37 move synchronously and are respectively arranged at intervals on the right side of the first reinforcing plate 36; the pushing end of each fourth electric push rod 37 extends vertically downward from the lower surface of the fixed plate 35 and is screwed and fixed to the corresponding position on the upper surface of the second lifting plate 38, and drives the second lifting plate 38 to move vertically up and down in the area directly above the conveying mechanism II 4; the present invention can synchronize the movements of the two fourth electric push rods 37 through the control of the controller. This is the prior art, so its principle will not be described in detail here.

[0059] like Figures 1-9As shown, the voltage detector 43 is spaced apart and positioned directly above the copper busbar at the right end of the busbar trough 3 after being limited by the second baffle 6, with its detection end vertically downward. The L-shaped plate 41 is positioned on the lower surface of the second lifting plate 38 relative to the voltage detector 43, with its horizontal side facing forward and its vertical side facing downward. The fixed end of the voltage detector 43 is installed on the lower surface of the horizontal side of the L-shaped plate 41, and its detection end extends vertically downward beyond the horizontal plane where the vertical end of the L-shaped plate 41 is located, ensuring that the L-shaped plate 41 is aligned with the copper busbar at the right end of the busbar trough 3 where the voltage detector 43 is inserted. The movement does not cause interference; a fifth electric push rod 42 is also provided horizontally and longitudinally on the rear side of the L-shaped plate 41. The tail of the fifth electric push rod 42 is fixedly connected to the corresponding position of the lower surface of the second lifting plate 38 through a fixed rod, and its pushing end is set in the forward direction and screwed to the outer surface of the vertical side of the L-shaped plate 41. Then, the fifth electric push rod 42 drives the voltage detector 43 to move horizontally and longitudinally within the coverage area of ​​the copper busbar at the right end of the busbar 3, and the fourth electric push rod 37 drives the voltage detector 43 to move vertically up and down, and inserts it into the copper busbar at the right end of the busbar 3 one by one.

[0060] like Figures 1-9 As shown, on the lower surface of the second lifting plate 38, a third slide rail 39 is provided horizontally and longitudinally at intervals in the horizontal longitudinal movement trajectory area of ​​the L-shaped plate 41. On the upper surface of the horizontal side of the L-shaped plate 41, a third slider 40 matching the third slide rail 39 is provided at each position of the third slide rail 39. The stability of the horizontal longitudinal movement of the L-shaped plate 41 is ensured by the cooperation of the third slide rail 39 and the third slider 40.

[0061] In this invention, a second electric push rod 28 is vertically provided on the left side of the square area enclosed by the four moving blocks 25 on the upper surface of the connecting plate 26. The second electric push rod 28 is spaced between two threaded rods 23 and positioned near the left moving block 25. Figures 1-9 As shown, the T-shaped plate 29 is positioned on the lower surface of the connecting plate 26 near the detection head 30, with its horizontal side on the upper side and its vertical side vertically downward. The fixed end of the detection head 30 is screwed onto the right side of the vertical side of the T-shaped plate 29, with its detection end facing horizontally to the right, ensuring that it is in the same vertical and horizontal plane as the busbar trough 3 on the conveying mechanism II 4. The pushing end of the second electric push rod 28 extends vertically downward from the lower surface of the connecting plate 26 and is screwed and fixed to the upper surface of the horizontal side of the T-shaped plate 29, driving the T-shaped plate 29 to move vertically up and down in the area above the conveying mechanism II 4. After the T-shaped plate 29 moves horizontally with the connecting plate 26 to directly above the left end of the busbar trough 3 after being limited by the second baffle 6, the detection end of the detection head 30 is vertically inserted into the left end of the busbar trough 3 by the second electric push rod 28.

[0062] The present invention also features four horizontally and longitudinally arranged third electric push rods 31 on the lower surface of the connecting plate 26, symmetrically arranged in a rectangle relative to the right side of the T-shaped plate 29. Figures 1-9 As shown, the pushing ends of the four third electric push rods 31 move synchronously, and their tails are all fixedly connected to the corresponding positions on the lower surface of the connecting plate 26 via fixed rods. The pushing ends of every two third electric push rods 31 are arranged in a straight line facing each other, and the pushing ends of the two third electric push rods 31 arranged on the same horizontal side are screwed and fixed to the outer side of the corresponding vertically horizontally arranged adjusting plate 32 near its upper end, ensuring that the two adjusting plates 32 are respectively arranged parallel and spaced on the front and rear sides of the busbar trough 3. Then, the third electric push rods 31 push the corresponding adjusting plates 32 to perform horizontal longitudinal reciprocating motion, and move vertically up and down and horizontally with the connecting plate 26. The present invention can synchronize the movements of the four third electric push rods 31 through the control of the controller. This is the prior art, so its principle will not be described in detail here.

[0063] like Figures 1-9 As shown, on the lower surface of the connecting plate 26, a second slide rail 33 is symmetrically arranged horizontally and longitudinally between the two adjusting plates 32. A second slider 34 matching the second slide rail 33 is also provided on the upper surface of each adjusting plate 32 relative to the position of each second slide rail 33. The cooperation of the second slider 34 and the second slide rail 33 ensures the stability of the horizontal longitudinal movement of the corresponding adjusting plate 32. The lower end of each adjusting plate 32 is vertically downward, and its lateral length is less than the length of the busbar trough 3. They are spaced apart on the right side of the detection head 30. The two adjusting plates 32 move in opposite directions along the horizontal longitudinal direction to correct the position of the busbar trough 3, ensuring that the busbar trough 3 is horizontally collinear with the detection head 30 and the voltage detector 43. A second rubber pad is also fixedly attached to the lower end of the inner side of each adjusting plate 32, protecting the busbar trough 3 during the correction process.

[0064] The upper limit position of the first lifting plate 19 must ensure that the detection head 30, the adjusting plate 32 and the voltage detector 43 do not interfere with the transmission of the busbar 3 through the conveying mechanism II 4, and its lower limit position must ensure that the adjusting plate 32 can correct the busbar 3 and is positioned directly above the conveying mechanism II 4 at intervals. At the same time, it must also ensure that the detection head 30 and the voltage detector 43 are respectively positioned directly above the corresponding end copper busbars of the busbar 3.

[0065] The motors, electric actuators, dust removal device 15, and fan 10 involved in this invention are all existing general-purpose products, and they are all controlled by a controller. This allows for precise control of the actions of the first motor 27, second motor 905, first electric actuator 18, second electric actuator 28, third electric actuator 31, fourth electric actuator 37, fifth electric actuator 42, dust removal device 15, and fan 10 according to the inspection operations of busbars 3 of different lengths. The start and end times of each action of the first motor 27, second motor 905, first electric actuator 18, second electric actuator 28, third electric actuator 31, fourth electric actuator 37, and fifth electric actuator 42 are obtained through repeated experiments and stored in the controller for easy retrieval later. Thus, when performing inspection operations on busbars 3 of a certain length, only the corresponding program instruction needs to be selected. This is a conventional control setting for motors and electric actuators, a technology known to those skilled in the art, and therefore will not be elaborated upon here.

[0066] The present invention provides a detection method for a busbar trunking assembly line type automatic detection device, such as... Figures 1-9 As shown, it includes the following steps:

[0067] Step 1: First, select the appropriate detection head 30 and voltage detector 43 according to the specifications of busbar 3, and screw the fixed end of the detection head 30 onto the right side of the vertical side of the T-shaped plate 29 to ensure that it is in the same vertical and horizontal plane as the busbar 3. Then, install the fixed end of the voltage detector 43 onto the lower surface of the horizontal side of the L-shaped plate 41.

[0068] Step 2: Then the busbar 3 is transferred to the gantry frame 1 via the conveying mechanism I2. After it is completely transferred to the right side of the first baffle 5, the first baffle 5 is raised to the highest position by the lifting assembly 9, and the right limit is applied to the next busbar 3.

[0069] Step 3: Then the busbar 3 is transferred from the conveying mechanism I2 to the conveying mechanism II4. During the process of passing through the cleaning component, the fan 10 continuously blows air onto the surface of the busbar 3 through the main air duct 11, the branch air duct 12 and the air outlet 13 in sequence, thereby removing the residual debris on the surface of the busbar 3. The residual debris is then collected by the dust removal device 15 through the collection cover 14.

[0070] Step 4: Then the second baffle 6 rises to the highest position through the corresponding lifting component 9 to limit the forward movement of the cleaned busbar 3 and ensure that the copper busbar at the right end of the busbar 3 is directly below the voltage detector 43.

[0071] Step 5: Then, based on the length of the busbar 3, under the drive of the first motor 27, the detection head 30 and the adjustment plate 32 are adjusted horizontally and laterally in sync with the connecting plate 26 until the detection head 30 is exactly above the copper busbar at the left end of the busbar 3 after being limited by the second baffle 6.

[0072] Step Six: Then, driven by the first electric push rod 18, the first lifting plate 19 descends to the lower limit position. At this time, the detection head 30 and the voltage detector 43 descend vertically to the corresponding end copper busbar position close to the busbar 3. Then, driven by the third electric push rod 31, the two adjusting plates 32 move towards each other in the horizontal longitudinal direction to correct the position of the busbar 3 so that the busbar 3 is set in a straight line with the detection head 30 and the voltage detector 43 in the horizontal direction.

[0073] Step 7: Then, driven by the second electric push rod 28, the detection end of the detection head 30 is vertically inserted into the left end of the busbar 3 into the copper busbar. Then, driven by the cooperation of the fourth electric push rod 37 and the fifth electric push rod 42, the voltage detector 43 is inserted into the right end of the busbar 3 into the copper busbar through vertical up and down and horizontal longitudinal movement. At this time, the insulation of the busbar 3 can be tested by the cooperation of the detection head 30 and the voltage detector 43.

[0074] Step 8: After the test is completed, the second baffle 6 descends to the lowest position. At this time, the tested busbar 3 is transferred to the gate frame 1 via the conveying mechanism II 4. At the same time, the first baffle 5 descends to the lowest position. Then, the above steps are repeated so that the next busbar 3 can be cleaned and then tested for insulation.

[0075] The beneficial effects of this invention are:

[0076] (1) The present invention can realize the automatic insulation detection of busbar trunking 3 in a production line manner, and this process saves time and effort and improves detection efficiency;

[0077] (2) The present invention first positions the busbar 3 transmitted by the conveying mechanism II4 through the second baffle 6, and then adjusts the horizontal position of the detection head 30 according to the length of the busbar 3 by the cooperation of the first motor 27, the threaded rod 23, the guide rail 24, the moving block 25 and the connecting plate 26, so as to facilitate the insulation detection of busbar 3 of different lengths. This process not only saves time and effort, but also saves equipment costs and has a wide range of applications.

[0078] (3) The present invention facilitates the front and rear positioning of the cleaned busbar 3 by using the third electric push rod 31, the adjusting plate 32, the second slide rail 33 and the second slider 34 in cooperation, so as to prevent the busbar 3 from deviating due to air blowing cleaning, thereby ensuring that the detection head 30 and the voltage detector 43 can be lowered and accurately inserted into the corresponding end copper busbar of the busbar 3, ensuring the smooth progress of the detection operation and improving the detection efficiency.

[0079] (4) The third electric push rod 31 and the adjusting plate 32 of the present invention can move horizontally and laterally synchronously with the connecting plate 26, thereby enabling position correction of busbars 3 of different lengths, and has a wide range of applications.

[0080] (5) The present invention facilitates the forward limit of the subsequent busbar 3 on the conveying mechanism I2 by the cooperation of the first baffle 5 and the corresponding lifting component 9, thereby ensuring that the busbar 3 can carry out the assembly line inspection operation in an orderly manner.

[0081] (6) The present invention facilitates the forward limit of the cleaned busbar 3 by cooperating with the second baffle 6 and the corresponding lifting component 9, thereby ensuring that the copper busbar at the right end of the busbar 3 is located directly below the voltage detector 43. Based on this, the horizontal position of the detection head 30 can be adjusted according to the length of the busbar 3, ensuring the smooth progress of the detection operation and improving the detection efficiency.

[0082] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, all modifications and improvements made by those skilled in the art to the technical solutions of the present invention should fall within the protection scope of the present invention.
