Description

Technical Field

[0001] The present invention relates to the technical field of new energy testing equipment, and in particular to a voltage withstand testing device for insulating parts used in the production of new energy charging piles. Background Art

[0002] The booming electric vehicle industry has made new energy charging piles an indispensable link between the power grid and electric vehicles. Their safety and reliability are directly related to user experience and personal safety. In the design, production and operation of charging piles, the pressure resistance of insulating components is the core element to ensure the stable and safe operation of charging piles.

[0003] At present, the voltage withstand test of the insulation components of charging piles mainly relies on the voltage withstand tester, which strictly verifies the insulation strength and voltage withstand capacity of the insulation components by applying a test voltage exceeding the rated voltage.

[0004] However, the traditional withstand voltage test method has significant limitations: each insulating component needs to be tested one by one, and the process is complicated and time-consuming. When faced with large-scale production or batch testing, this inefficient testing method is difficult to meet the fast production rhythm. In addition, there are many types of insulating components that need to be tested in charging piles, including insulating partitions in circuit breakers, arc extinguishing chamber insulating parts, switch insulating seats, contactor insulating pads, etc., and the voltage required for testing each component is different. The voltage setting needs to be adjusted frequently during the test, which further reduces the detection efficiency.

DETAILED DESCRIPTION

[0029] The following will be combined with 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 of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0030] See also Figure 1-9 The present invention provides a technical solution: a voltage withstand test device for insulating parts used in the production of new energy charging piles, such as Figure 1 As shown, it includes a chain conveyor 3 for transmitting insulating parts, a test section 5 in which a plurality of belt conveyors 4 are arranged in a longitudinal array and for testing respective insulating parts, a voltage tester 2 connected to the test section 5, and a transfer section connected between the chain conveyor 3 and the test section 5, the transfer section receiving the insulating parts of the chain conveyor 3 and classifying them and then transporting them to the test section 5 at a corresponding position for testing.

[0031] like Figure 1 As shown, the test section includes a first bracket 1, and a plurality of belt conveyors 4 are arranged in a longitudinal array on the first bracket 1. Figure 8 , 9As shown, each belt conveyor 4 is provided with two groups of rollers 41 on both sides in the horizontal direction, each group is provided with two rollers, and the rollers 41 are located in the middle position in the longitudinal direction of the belt conveyor 4. The rollers 41 on both sides respectively press down on both sides of the belt at the middle position of the belt conveyor 4, so that a concave space is formed downward on both sides of the belt at this position of the belt conveyor 4. The concave space makes the lower surface of the insulating part suspended in the air at this position, so as to facilitate the subsequent support and clamping of the insulating part on the belt. A laser sensor 411 is provided on the roller 41 close to the chain conveyor 3. After the insulating part passes through the position of the roller 41 with the laser sensor 411 under the transmission of the belt conveyor 4, the equipment can accurately know the position of the insulating part, so as to better control the timing of the subsequent mechanism action.

[0032] Each belt conveyor 4 is provided with a support mechanism 53 on the outside of the concave space on both sides thereof, that is, there are multiple support mechanisms 53, two in a group, and each group of support mechanisms 53 is respectively arranged on both sides of one of the belt conveyors 4. One lateral end of the support mechanism 53 is located outside the concave space, and a support seat 54 is provided on this end to support the L-pole test point or N-pole test point of the electrically connected withstand voltage tester 2, and the bottom of the support seat 54 is provided with an inclined surface on the side close to the belt conveyor 4. The other end of the support mechanism 53 is connected to a driving mechanism 7 that drives its lateral movement, and the support mechanisms 53 on the opposite sides are driven by the driving mechanism 7 to perform lateral relative movement to support and clamp the insulating parts on the belt. The voltages provided by the L-pole test points and N-pole test points provided on each group of support mechanisms 53 are respectively the same as the voltages required for the corresponding insulating parts test.

[0033] A guide plate 6 is arranged on the outside of the belt conveyor 4 in parallel with the support mechanism 53, and a first slide groove 61 is provided on the guide plate 6. The front section and the rear section of the first slide groove 61 are horizontal, and the middle section is an inclined section connecting the front section and the rear section. A slide bar 73 is inserted into the first slide groove 61, and the slide bar 73 is fixedly connected to the support mechanism 53, so that the support mechanism 53 is guided by the first slide groove 61 when it moves horizontally. The front section of the first slide groove 61 is far away from the belt position, and in the vertical direction, the front section is lower than the rear section, so that when the support mechanism 53 slides and clamps relatively in the horizontal direction, it is first in a horizontal low position and then slides to a horizontal high position.

[0034] A pressing and fixing mechanism 8 is installed above the supporting mechanism 53. After the supporting mechanism 53 supports and clamps both sides of the insulating member, the pressing and fixing mechanism 8 presses down to drive both sides of the insulating member to fit with the L-pole test point and the N-pole test point on the supporting seat respectively.

[0035] The various mechanisms in the testing unit 5 cooperate to test the insulating component, and the specific process is as follows.

[0036] When the belt conveyor 4 transports the insulating part to the roller 41 at the first position, the laser sensor 411 on the roller 41 senses and starts the subsequent action. When the insulating part enters between the two groups of rollers 41, since there is a concave space formed on both sides of the belt, the lower surfaces of both sides of the insulating part are in a suspended state, and the support mechanism 53 is driven by the driving mechanism 7 and relatively close. The support seat 54 on the support mechanism 53 is inserted under both sides of the insulating part, so that both sides of the insulating part are located above the L pole test point and the N pole test point. When the support mechanism 53 moves relatively, it is guided by the guide plate 6. When it is relatively close in the early stage, it is at a lower position in the vertical direction along the front section of the first slide 61. At this time, the support seat 54 is inserted under the insulating part, and then passes through the middle section and tilts upward to enter the rear section. The support seat 54 lifts the insulating part to a certain extent, so that the insulating part is separated from the belt. Then the downward fixing mechanism 8 is pressed down, driving the two sides of the insulating part to press down and closely contact the L pole test point and the N pole test point, and then the insulating part is tested.

[0037] The L-pole test point and the N-pole test point are electrically connected to a withstand voltage tester located on one side of the first bracket. The insulating parts have been sorted to the corresponding belt conveyor in the previous transfer department, and the voltage matches the voltage required for the insulating parts test.

[0038] like Figure 8 , 9 As shown, a plurality of first telescopic tubes 51 are vertically installed on the outer side of the first bracket 1, one end of the first telescopic tube 51 is fixed on the first bracket, and the other end is installed with a sleeve 52, and the support mechanism 53 is slidably installed in the sleeve 52. The first telescopic tube 51 assists the support mechanism in sliding horizontally, and is guided by the first slide groove 61 to move in the vertical direction.

[0039] like Figure 8 , 9 As shown, the driving mechanism 7 includes a telescopic cylinder 71 installed on one side of the belt conveyor 4, and a telescopic rod 72 is vertically fixed to the end of the telescopic cylinder 71 away from the belt conveyor 4, and the end of the telescopic rod 72 away from the top of the telescopic cylinder 71 is fixed to the supporting mechanism 53.

[0040] like Fig. 9As shown, the downward pressing fixing mechanism 8 includes a fixing seat 83 installed on the supporting seat 54, a first servo motor 81 is arranged on the fixing seat 83, a cam 82 is fixed on the output shaft of the first servo motor 81, and second spring telescopic tubes 84 are arranged on both sides of the cam. The upper end of the second spring telescopic tube is fixedly connected to the fixing seat, and the lower end is connected to a clamping plate 85, and the clamping plate is located above the corresponding test point. The clamping plate 85 is driven to press down by the rotation of the cam 82 or is restored by the second spring telescopic tube 84. The first servo motor 81 rotates to rotate the cam 82. When the cam 82 rotates to the protruding end downward, the clamping plate 85 is driven to press the insulating member downward. When the cam rotates to the non-protruding end, the clamping plate 85 is reset through the second spring telescopic tube.

[0041] The transfer section includes a second bracket 9 arranged between the chain conveyor 3 and the testing section, such as Figure 5 As shown, a transfer mechanism is installed on the second bracket 9, and trays 10 are evenly arrayed on the transfer mechanism 11. There are multiple trays 10, and weighing sensors 101 are arranged inside. The accuracy of the weighing sensor 101 is at least gram level, which is the prior art. A support plate 102 is installed on the weighing sensor 101 for placing insulating parts.

[0042] The transfer mechanism 11 moves and transports the pallet 10 along a square track, and the side of the support plate 102 that contacts the insulating member is always parallel to the ground.

[0043] A plurality of pushing mechanisms 12 are also installed on the second bracket 9. The pushing mechanisms 12 correspond to the belt conveyors 4 respectively and are electrically connected to the weighing sensors 101. The pushing mechanisms 12 identify the types of insulating parts according to the weight obtained by the weighing sensors on the pallet and convey the insulating parts to the corresponding belt conveyors 4 for testing.

[0044] like Figure 2 , 4 As shown in Figure 5, the transfer mechanism 11 includes a driving member 111 and a limiting member 112. The driving member 111 drives the tray 10 to move in a square track, and the limiting member 112 limits the posture of the tray 10 during movement. The contact surface between the support plate 102 and the insulating member is always facing upwards through the tray 10 and the weighing sensor 101. Figure 4As shown, the driving member 111 includes sprockets 1111 and chains 1112 symmetrically arranged on the inner walls of both sides of the second bracket 9. At least four sprockets 1111 are fixed to each side of the second bracket 9. The sprockets 1111 are connected by chains 1112. Second servo motors 1113 are respectively installed on the outer walls of the second bracket 9. The output shaft of the second servo motor 1113 is fixed to the mounting shaft of one of the sprockets 1111 corresponding to it and drives the sprocket 1111 to rotate. Rotating rods 1114 are respectively fixed on both sides of the tray 10. The rotating rods 1114 penetrate the corresponding chains 1112 and are rotatably connected to the chains 1112. Multiple trays 10 are evenly distributed between the two chains 1112 and transported by the chains 1112.

[0045] like Figure 3 , 6 As shown in Figures 7 and 8, the limiting member 112 includes second slide grooves 1121 respectively opened on the inner walls of both sides of the second bracket 9, and the second slide grooves 1121 can be divided into two parts, one part is a square groove, the square groove includes vertical grooves 1128 vertically arranged on the left and right and horizontal grooves horizontally arranged on the upper and lower parts, and the four corners of the square groove are rounded, that is, the vertical grooves 1128 and the horizontal grooves are connected with rounded corners, and the other part is a vertical groove 1129 that is offset outward from the center and arranged in parallel by the vertical grooves 1128 of the square groove, and both ends of the vertical grooves 1129 are also connected with the horizontal grooves with rounded corners, and the groove width of the vertical grooves 1129 is equal to the groove width of the square groove, and guide rods 1127 are respectively provided on the outer sides of the upper and lower horizontal grooves. The limiting member 112 also includes a cross 1122 fixed on the rotating rod 1114, which is composed of a first support rod and a second support rod crossed in a cross shape. The first support rod is fixed with a first roller 1124 at both ends through a first support rod 1123, and the second support rod is fixed with a second roller 1126 at both ends through a second support rod 1125. The length of the first support rod 1123 is greater than that of the second support rod 1125, and the offset distance between the vertical groove 1129 and the vertical groove 1128 matches the distance between the first rollers 1124 at both ends of the first support rod. The first rollers 1124 at both ends of the first support rod slide vertically in the vertical groove 1128 and the vertical groove 1129, respectively, or slide horizontally in the horizontal groove at the same time, and the second rollers 1126 at both ends of the second support rod are either suspended outside the second slide groove 1121 or limited outside the guide rod 1127.

[0046] like Figure 4 As shown, the pushing mechanism 12 includes a straight hole 121 opened on one side of the second bracket 9, a straight groove 122 opened on the inner wall of the other side, an electric push rod 125 installed on the outer wall of the second bracket 9, and a push plate 123 installed in the second bracket 9. Slide bars 1231 are fixed on both sides of the push plate 123. The slide bar 1231 on one side is located in the straight groove 122, and the slide bar 1231 on the other side passes through the straight hole 121 and is sleeved with a fixing ring 124. The top of the electric push rod 125 is fixedly connected to the fixing ring 124.

[0047] The chain conveyor 3 conveys the insulating parts to the pallet 10. At this time, the pallet is located near the chain conveyor 3. The weighing sensor 101 on the pallet 10 weighs the insulating parts and then classifies the insulating parts. When the pallet 10 is transported to the side close to the testing part 5, the insulating parts are transported to the corresponding belt conveyor 4. When the pallet 10 moves on the transfer mechanism 11, the support plate 102 on the pallet 10 needs to be kept in a horizontal position to ensure the smooth transportation of the insulating parts, which is mainly achieved by the cooperation between the first roller 1124, the second roller 1126 and the second slide 1121 on both sides of the pallet 10. When the pallet 10 is transported vertically upward, the first rollers 1124 at both ends of the cross 1122 are respectively located in the vertical groove 1128 and the vertical groove 1129 to slide up and down, and the second rollers 1126 are suspended outside the second slide groove 1121. When moving to the corner position, the first rollers 1124 at both ends slide into the horizontal groove, and one of the second rollers 1126 slides outside the guide rod 1127. When it reaches the rounded corner position again, the first rollers 1124 at both ends slide into the vertical groove 1128 and the vertical groove 1129 respectively, and the second rollers 1126 are suspended outside the groove. When sliding to the bottom, the other second roller 1126 slides outside the guide rod 1127. The entire pallet 10 is sequentially formed into a square for movement and transportation, and its horizontal position is maintained.

[0048] When the tray 10 moves to the corresponding position of the belt conveyor 4, the electric push rod 125 pushes the push plate 123, and the push plate pushes the insulating member into the belt.

[0049] The whole working process is described below.

[0050] Working principle: The chain conveyor 3 runs at a relatively low speed, and the staff places insulating parts on the conveyor plates on the chain conveyor 3, with a rule of placing an insulating part every X conveyor plates, X ≥ 1. Under the operation of the chain conveyor 3, the insulating part slides from the discharge end of the chain conveyor 3 and falls onto the support plate 102 on one of the trays 10, and applies pressure to the support plate 102. Under the action of the weighing sensor 101, the equipment determines the type of the insulating part based on the different weights measured. It should be noted that if Figure 3 As shown, the conveying plate at the discharge end of the chain conveyor 3 will be inclined to facilitate the sliding of the insulating parts. The height of one of the belt conveyors 4 is matched with the discharge height of the chain conveyor 3. Then, one of the push plates 123 is arranged on one side of the tray 10 to prevent the insulating parts from sliding too far and falling, thereby blocking one side of the support plate 102.

[0051] The second servo motor 1113 is started, and the second servo motor 1113 drives the sprocket 1111 to rotate through the shaft of the fixed sprocket 1111, and the sprocket 1111 drives the sprocket 1111 to rotate synchronously through the chain 1112. Since the four sprockets 1111 are arranged in a square shape, the chain 1112 is also square. During the transmission process, the chain 1112 drives the tray 10 to perform the same square trajectory transmission through the rotating rod 1114. During this process, the first roller 1124 connected to the first support rod 1123 on the cross 1122 at the end of the rotating rod 1114 is restricted by the second slide groove 1121, so that the rotating rod 1114 cannot rotate. In this state, when the support plate 102 moves to the left and right sides of the second slide groove 1121, it always maintains a fixed posture and does not rotate. When the tray 10 moves to the corner position of the second slide groove 1121, the first roller 1124 is located in the straight horizontal groove at the top of the second slide groove 1121, and the rotation direction of the chain 1112 The pallet 10 applies a force to move to the right, and the second roller 1126 at the upper end contacts the top surface of the guide rod 1127. At this time, under the restrictions of the first roller 1124, the transverse groove part of the second slide groove 1121, the top second roller 1126, and the guide rod 1127, the cross 1122 restricts the pallet 10 from rotating through the rotating rod 1114, and continues to move along the movement trajectory of the chain 1112. The same is true when the pallet 10 moves to other corners, that is, the insulating parts on the support plate 102 are always stably supported by the support plate 102 to prevent the insulating parts from falling during transportation.

[0052] Since the insulating parts have been identified after falling onto the support plate 102, as the chain 1112 rotates, it stops when it rotates to the side of the belt conveyor 4 corresponding to the withstand voltage test, and the electric push rod 125 starts, and drives the push plate 123 to move in the straight hole 121 through the slide bar 1231. The push plate 123 drives the insulating parts to leave the support plate 102 and enter the belt conveyor 4 corresponding to the withstand voltage test. Then the electric push rod 125 is reset to facilitate the transportation of subsequent insulating parts. The support plate 102 close to the side of the chain conveyor 3 continues to support the insulating parts that slide down subsequently.

[0053] It should be noted that when there are different types of insulating parts on multiple support plates 102 , the second servo motor 1113 can preferentially transport each different type of insulating part to the corresponding position of the belt conveyor 4 , and transfer the insulating part to the belt conveyor 4 through the corresponding pushing mechanism 12 .

[0054] The belt conveyor 4 is turned on and drives the insulating part to move. When the insulating part passes through the first roller 41, it is detected by the laser sensor 411. After a short transmission, the belt conveyor 4 stops working to ensure that the L-pole test point and the N-pole test point can smoothly contact the insulating part.

[0055] After the insulating part is transferred to the belt conveyor 4, it fits tightly with the belt conveyor 4, making it inconvenient to perform a clamping test on the insulating part. However, the concave space formed by the downward pressure of the roller 41 on both sides of the middle position of the belt conveyor 4 makes the two sides of the insulating part suspended, which is convenient for clamping the insulating part.

[0056] When the insulating member is located at a suitable point on the belt conveyor 4, the telescopic cylinders 71 on both sides of the belt conveyor 4 are started at the same time, and the corresponding support mechanisms 53 are driven to approach in relative directions through the telescopic rods 72, thereby driving the support seat 54 to clamp the insulating member. In the process of driving the support mechanism to move, the slide bar 73, under the guidance of the first slide groove 61, limits the support mechanism to move toward the center position of the belt conveyor 4, first moves a certain distance at a low position, then moves upward, and then moves to the center position of the belt conveyor 4. In this process, the test point of the support seat 54 will first contact the bottom of the insulating member, and then the insulating member will break away from the contact with the belt conveyor 4, and then clamp the insulating member. After that, the first servo motor 81 is started to drive the cam 82 to rotate, and the cam 82 rotates to press the clamping plate 85, and the clamping plate 85 applies a downward force to the insulating member, so that the insulating member is closely fitted with the corresponding test point. Then the withstand voltage tester 2 is turned on to test the insulating member. After the test, the equipment automatically determines whether the product is qualified. This is a prior art, so it will not be described in detail.

[0057] It should be noted that the start-up timing and coordination conditions of various electronic devices in the device can be controlled by simple programming of a compiler, which is a prior art. Embodiment 2

[0058] See also Figure 1 , 2 4. Based on Example 1, this application further optimizes this solution: A third bracket 13 is provided at the discharge end of the belt conveyor 4, and a collecting box 14 is provided on the third bracket 13. The number of collecting boxes 14 is twice that of the belt conveyor 4, and every two collecting boxes 14 correspond to one belt conveyor 4. The two collecting boxes 14 correspond to the lower position of half of the discharge end of the belt conveyor 4 respectively.

[0059] Since the driving source of the supporting mechanism is its own telescopic cylinder 71, after measuring the insulating parts, the telescopic cylinder 71 on one side can continue to extend and the telescopic cylinder 71 on the other side can be retracted according to whether the product is qualified, thereby controlling the insulating parts to be on the left or right side of the conveying surface of the belt conveyor 4, and then driving the insulating parts to fall into different collection boxes 14 to distinguish qualified products from unqualified products.
