Description

Technical Field

[0001] The present invention relates to the technical field of relay processing equipment, and in particular to a relay transmission device and a turnover conveyor thereof, and a relay transmission system. Background Art

[0002] Relay is an important electrical control device, playing an important role in the field of power system and automation control. The production method of relay is relatively complicated, usually needing to go through multiple consecutive steps to obtain. Therefore, to ensure a high pass rate of relays, it is necessary to ensure that the relay parts can be accurately transported to the corresponding processing points in each step.

[0003] For example, the patent with application number CN201510467561.7 discloses a circuit breaker assembly device, which includes a conveying mechanism and an assembly mechanism. The conveying mechanism includes a frame, conveying rollers arranged between the frames, a lifting and translating device arranged below the conveying rollers, and a plurality of baffles arranged between the conveying rollers. The lifting and translating device includes a plurality of chains arranged between the conveying rollers, the chains are arranged perpendicular to the rolling direction of the conveying rollers, the baffles are parallel to the chains, and the baffles are arranged on one side of the chains for blocking the circuit breaker from being transported; the assembly mechanism is fixedly arranged on one side of the conveying mechanism, and the assembly mechanism includes an assembly frame, a transmission device, a control console and an assembly table, wherein the conveying device is arranged on the inner side of the assembly frame.

[0004] The invention provides a way to combine assembly line production and assembly mechanism for circuit breaker mechanism, which improves assembly efficiency, reduces labor intensity of staff, realizes offline repair or testing, and is not limited to the existing assembly mechanism that only delivers similar products on one assembly line. The assembly line production idea provided by the above patent can also be applied to the production process of other electronic components such as relays.

[0005] If assembly line production is introduced into the relay processing flow, some relay parts need to be processed in the current processing mechanism and then transferred to the next processing mechanism through the conveying mechanism. After the relay parts are placed on the connecting end of the conveying mechanism connected to the next processing mechanism, if the position of the relay parts needs to be slightly adjusted to align with the corresponding processing point, it is necessary to drive the conveying rollers in the conveying mechanism to adjust the positions of all the relay parts on it. This process will drive other relay parts that are not placed at the connecting end to move together, which may cause the relay parts on the conveying mechanism to conflict with the relay parts produced by the previous processing mechanism. If an independent conveying mechanism is added between the conveying mechanism and the processing mechanism, it is easy to cause too many devices involved in the assembly line, which is too complicated, which is not conducive to transmission control and subsequent repair and maintenance. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a relay transmission device, which as a whole includes two parts, a main transmission part and a secondary transmission part, wherein the secondary transmission part is connected to the next processing mechanism. Normally, the transmission directions of the two are consistent, and when the relay parts are transmitted to the secondary transmission part and need to be adjusted in position here, the secondary transmission part can operate independently of the main transmission part, so that the position of the relay parts on the secondary transmission part can be adapted to the processing point, and at the same time, when the relay parts are adjusted in position, they will not conflict with other relay parts on the relay transmission device.

[0007] The present invention is achieved through the following technical solutions: A relay transmission device, comprising a main transmission part and a secondary transmission part movably connected to the main transmission part; the main transmission part comprises a main transmission wheel group, the secondary transmission part comprises a secondary transmission wheel group, the main transmission wheel group and the secondary transmission wheel group are connected to each other through a transmission chain; one end of the main transmission part close to the secondary transmission part is a transition end, and a top adjustment kit and a bottom adjustment kit are arranged on the transition end; wherein, on the top adjustment kit, a first driving wheel, a first receiving wheel and a first guide wheel are arranged in sequence from the transition end to a direction away from the transition end, the first receiving wheel is movably mounted on the main transmission part, and a first spacing is formed between the first receiving wheel and the main transmission wheel group; on the bottom adjustment kit, a second driving wheel, a second receiving wheel and a second guide wheel are arranged in sequence from the transition end to a direction away from the transition end, the second receiving wheel is movably mounted on the main transmission part, and a second spacing is formed between the second receiving wheel and the main transmission wheel group.

[0008] First of all, in the present invention, the top adjustment kit and the bottom adjustment kit can respectively achieve a tensioning effect on the transmission chain by adjusting the first spacing or the second spacing, and can achieve a tensioning effect on the transmission chains on the main transmission part and the auxiliary transmission part at the same time. This structure ensures the normal operation of the relay transmission device as a whole under normal conditions.

[0009] Secondly, when it is necessary to adjust the position of the relay parts placed on the secondary transmission part, the operation of the main transmission part can be suspended and the operation of the secondary transmission part can be carried out alone. For example, after stopping the operation of the main transmission part, the transmission chain temporarily stored in the bottom adjustment kit can be released by reducing the second spacing, and the second drive wheel and the first drive wheel can be started to rotate clockwise to drive the secondary transmission wheel group to continue to operate, while expanding the first spacing, and all the transmission chains released from the bottom adjustment kit are temporarily stored in the top adjustment kit. During this operation, the relay parts on the secondary transmission part can be displaced a certain distance to the position of the main transmission part, so as to achieve the effect of adjusting the position of the relay parts, so that the relay parts can be placed at the accurate processing point, and the processing qualification rate is improved; at the same time, it is ensured that the position adjustment of the relay parts on the secondary transmission part will not conflict with the relay parts carried on the main transmission part.

[0010] As a further improvement of the present invention, at least one guide kit is installed on the main transmission part for limiting and guiding the movement path of the first receiving wheel and / or the second receiving wheel away from or close to the main transmission part.

[0011] As a further improvement of the present invention, the guide kit includes a shell and a guide groove provided on the shell, and the first receiving wheel and / or the second receiving wheel are movably installed in the guide groove.

[0012] As a further improvement of the present invention, at least one electric drive kit is installed on the main transmission part, which is used to drive the first receiving wheel and / or the second receiving wheel to move away from or close to the main transmission part.

[0013] As a further improvement of the present invention, the electric drive kit includes a transmission rod, a telescopic drive rod and a control kit, wherein one end of the transmission rod is connected to the first receiving wheel or the second receiving wheel, and the other end is connected to the extending section of the telescopic drive rod, and the control kit is used to control the telescopic amount of the extending section.

[0014] In a second aspect, the present invention provides a flip conveyor, which adopts any one of the above-mentioned relay transmission devices, wherein the flip conveyor includes a fixed part, a flip part and a flip drive kit, the main transmission part is arranged in the fixed part, and the auxiliary transmission part is arranged in the flip part.

[0015] The above relay transmission device can be used not only at the end of the relay transmission system connected with the processing mechanism, but also in the middle of the relay transmission system. The overall length of the relay transmission system in the assembly line is lengthened, so some relay transmission devices may need to be placed near the drop-down fire door of the production plant, and the conveyor placed there is preferably equipped with a flipping part that can be flipped and moved, so that when a fire occurs, the flipping part can be lifted to facilitate the lowering of the fire door.

[0016] When the above-mentioned relay transmission device is placed in the middle of the relay transmission system, it can simultaneously meet two requirements. First, in the event of a fire or the like, the operation of the main transmission part can be quickly stopped to stop the transmission of relay parts to the workshop where the fire occurred; second, the relay parts stranded on the secondary transmission part can be urgently transferred back to the fixed part through the independent operation of the secondary transmission part. At the same time, since the secondary transmission part is also arranged on the flipping part of the flip conveyor, after the relay parts are urgently transferred, the secondary transmission part can cooperate with the lifting work of the flipping part. The process of "transferring first and then flipping" avoids the damage of the relay parts from falling, and especially avoids the lighter relay parts from falling to the falling point of the fire door, causing the fire door to fail to be lowered.

[0017] The flip conveyor of this structure can also ensure that the transmission chain remains tensioned and does not fall off during the flipping of the flipping part, and because the top adjustment kit and the bottom adjustment kit with tensioning function are both arranged on the main transmission part, i.e., the fixed part, the overall weight of the flipping part is relatively small, so that the driving force required for flipping is also relatively small and the flipping speed is also relatively fast.

[0018] Here, the relay transmission device is in the overturning conveyor, and the cooperation for the overturning work is as follows: When the secondary transmission part on the flipping part rotates relative to the main transmission part on the fixed part, the spacing between the two will change, thereby causing the transmission chain connected between the two to be partially tightened or loosened. The transmission chain can be adjusted in the top adjustment kit and the bottom adjustment kit to ensure that the entire transmission chain always fits on the main transmission wheel set and the secondary transmission wheel set without falling off. Specifically, when the secondary transmission chain is flipped clockwise, the transmission chain at the bottom connected between the main transmission part and the secondary transmission part will be over-tightened, while the transmission chain at the top will pile up and become loose. Therefore, the second spacing can be reduced on one hand to release the transmission chain originally temporarily stored in the bottom adjustment kit to reduce the over-tightening of the transmission chain at the bottom, and the first spacing can be increased on the other hand to actually temporarily store part of the transmission chain at the top in the top adjustment kit to avoid the occurrence of situations such as the transmission chain at the top piling up and becoming loose and eventually falling off.

[0019] As a further improvement of the present invention, the flip drive kit includes a flip arm, a flip shaft and a flip drive device; wherein the flip shaft passes through the fixed part; the flip drive device is installed on the side wall of the fixed part and is transmission-connected to the flip shaft; the flip arm is arranged on both sides of the fixed part, one end of which is fixedly connected to the flip part, and the other end is connected to the flip shaft.

[0020] As a further improvement of the present invention, the flip arm includes a first connecting section, a second connecting section and a connecting section connecting the first connecting section and the second connecting section, wherein the first connecting section is connected to the flip axis, and the second connecting section is connected to the flip part.

[0021] As a further improvement of the present invention, the flip conveyor also includes at least one flip guide, which includes a guide plate installed on the side wall of the fixed part and a guide protrusion installed on the flip arm, and the guide protrusion is embedded in the flip guide groove on the guide plate.

[0022] In the third aspect, the present invention provides a relay transmission system, comprising any one of the above-mentioned relay transmission devices or any one of the above-mentioned overturning conveyors. The relay transmission system with the above-mentioned relay transmission device can improve the accurate control of relay parts, and the number of devices required is generally small, which is conducive to automated control and subsequent repair and maintenance of the devices; and the above-mentioned overturning conveyor ensures the safety of the processing plant, especially the length of the overturning part in the present invention can be longer, so that the fire door used near the location of the overturning conveyor in the plant can be a thicker double-layer fire door, etc., which expands the choice of related designs.

[0023] The beneficial effects of the present invention are: (1) The relay transmission device can maintain the independent operation of the auxiliary transmission part on the basis of stopping the operation of the main transmission part, and perform separate and accurate position adjustment on the relay parts stranded on the auxiliary transmission part without causing conflict with the relay parts on the main transmission part. This ensures the smooth progress of relay processing and improves the accuracy of relay processing, thereby improving the processing qualification rate of relays; (2) In the relay transmission device of the present invention, the two parts of the structure can operate independently, so that one relay transmission device can perform the functions that can only be achieved by two independent transmission devices in the existing assembly line; at the same time, the first driving wheel and the second driving wheel provided on the main transmission part serve as the driving device of the transmission chain placed in the auxiliary transmission part, and the first receiving wheel and the second receiving wheel serve as the tensioning device of the transmission chain placed in the auxiliary transmission part, which makes the structure of the relay transmission device itself simpler, more convenient for automatic control, and also conducive to the subsequent maintenance of the device; (3) The relay transmission device of the present invention is applied to the overturning conveyor. On the one hand, when the secondary transmission part on the overturning part is displaced or rotated, and the transmission chain connected between the secondary transmission part and the main transmission part may be over-tightened or loosened, the relay transmission device of the present invention can adjust the transmission chain through the top adjustment kit and the bottom adjustment kit, thereby ensuring that the transmission chain is not damaged or falls off during the displacement or overturning of the secondary transmission part, thereby ensuring the normal operation of the overturning conveyor; on the other hand, the top adjustment kit and the bottom adjustment kit that play a tensioning role are both arranged on the main transmission part of the fixed part, so the number of devices required to be installed on the overturning part is reduced, the overall mass of the secondary transmission part is reduced, the driving force required for displacement or overturning of the secondary transmission part is smaller, and the secondary transmission part does not need to be connected to external components such as wires, thereby reducing the possibility of being affected during its displacement or overturning. The above functions ensure the smooth development of the overturning work of the overturning conveyor and the smooth lowering of the fire door, and can reduce the loss of relay parts when accidents such as fire occur in the factory.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below based on the accompanying drawings and implementation examples.

[0026] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0027] Embodiment 1: This embodiment provides a relay transmission device, which mainly includes two parts: a main transmission part A01 and an auxiliary transmission part A02, wherein the main transmission part A01 is relatively fixed, and the auxiliary transmission part A02 is movably connected to the main transmission part A01 and can be displaced, flipped, etc. relative to the main transmission part A01.

[0028] like Figure 1~Figure 2 As shown, the main transmission part A01 includes a main transmission wheel set A01-1, and the auxiliary transmission part A02 includes an auxiliary transmission wheel set A02-1, and the main transmission wheel set A01-1 and the auxiliary transmission wheel set A02-1 are connected by the same transmission chain A03. Therefore, in the relay transmission device, the driving device and tensioning device required by the transmission chain A03 can all be set on the main transmission part A01, thereby reducing the total number of parts in the auxiliary transmission part A02, reducing the overall weight of the auxiliary transmission part A02, making the driving force required to move or flip the auxiliary transmission part A02 smaller, and making it easier to control the displacement and flipping amount of the auxiliary transmission part A02.

[0029] Specifically, one end of the main transmission part A01 close to the secondary transmission part A02 is the transition end A01-2, and the top adjustment kit A04 and the bottom adjustment kit A05 are arranged on the transition end A01-2. On the top adjustment kit A04, the first driving wheel A04-1, the first receiving wheel A04-2 and the first guide wheel A04-3 are arranged in sequence from the transition end A01-2 to the direction away from the transition end A01-2; and at the same time, on the bottom adjustment kit A05, the second driving wheel A05-1, the second receiving wheel A05-2 and the second guide wheel A05-3 are also arranged in sequence from the transition end A01-2 to the direction away from the transition end A01-2.

[0030] Among them, the first driving wheel A04-1 and the second driving wheel A05-1 act as driving devices. In this embodiment, the two can cooperate with the other driving wheels arranged in the main transmission wheel group A01-1 to drive the movement of the entire transmission chain A03.

[0031] The first receiving wheel A04-2 and the second receiving wheel A05-2 are movably mounted on the main transmission part A01, and a first spacing L1 and a second spacing L2 are formed between the first receiving wheel A04-2 and the main transmission wheel group A01-1, respectively. This movable mounting method needs to be able to achieve the first receiving wheel A04-2 and the second receiving wheel A05-2 to be fixed after being away from or close to the main transmission part A01, and its specific structure is relatively diverse. For example, two bases away from the main transmission part A01 are set, and the first receiving wheel A04-2 and the second receiving wheel A05-2 are respectively mounted on the two bases by screws. By rotating the screws, the first receiving wheel A04-2 and the second receiving wheel A05-2 can be controlled to be away from or close to the main transmission part A01, that is, the size of the first spacing L1 and the second spacing L2 can be controlled. Any mounting structure that can change the size of the first spacing L1 and the second spacing L2 and fix them can achieve the above effect. Under the above structure, by adjusting the sizes of the first spacing L1 and the second spacing L2, the first receiving wheel A04-2 and the second receiving wheel A05-2 can achieve the tensioning effect on the entire transmission chain A03, and the two actually play the role of tensioning devices.

[0032] And as Figure 1 As shown, there is a transmission chain A03 connecting the main transmission wheel group A01-1 and the auxiliary transmission wheel group A02-1 near the transition end A01-2, wherein the first receiving wheel A04-2 and the second receiving wheel A05-2 in the top adjustment kit A04 and the bottom adjustment kit A05 can store or release the transmission chain A03 when adjusting the first spacing L1 and the second spacing L2, thereby ensuring the independent operation of the auxiliary transmission part A02.

[0033] When the relay transmission device in this embodiment is placed at one end of the relay transmission system and connected to the processing mechanism, the secondary transmission part A02 is the main connection part, that is, the relay parts are transferred to the secondary transmission part A02 and then transported or directly processed on the secondary transmission part A02. Therefore, the relay parts on the secondary transmission part A02 may need to be slightly adjusted in position to accurately match the requirements of the processing mechanism. Under the structure of this embodiment, the relay parts can change their position on the secondary transmission part A02 without affecting the relay parts placed on the main transmission part A01 to be transmitted later.

[0034] The realization of this function relies on the top adjustment kit A04 and the bottom adjustment kit A05. First, when the required amount of relay parts are carried on the secondary transmission part A02 and the position of the relay parts needs to be adjusted, the remaining driving wheels in the main transmission wheel set A01-1 can first stop rotating to suspend the transmission of the relay parts thereon. Then, the second spacing L2 can be reduced in the bottom adjustment kit A05 and the second drive wheel A05-1 can be started. Synchronously, the first spacing L1 can be enlarged in the top adjustment kit A04 and the first drive wheel A04-1 can be started. The two cooperate with each other, and the temporarily stored transmission chain A03 is released through the bottom adjustment kit A05, and the top adjustment kit A04 receives the transmission chain A03. At the same time, the first drive wheel A04-1 and the second drive wheel A05-1 jointly drive the transmission chain A03 to be transmitted in the specified direction, thereby driving the operation of the secondary transmission wheel group A02-1, and adjusting the displacement of the relay parts on the secondary transmission part in the direction of the main transmission part. If adjustment is required in the opposite direction, the transmission chain A03 received by the bottom adjustment kit A05 and the top adjustment kit A04 can release the temporarily stored transmission chain A03. The main transmission part A01 is not started and is not involved during this process. The changes in the structure of the relay transmission device in this process can be referred to. Figure 1 to Figure 2 Structural changes in the form.

[0035] Preferably, in this embodiment, two guide kits A06 are also installed on the main transmission part A01, which are used to limit and guide the first receiving wheel A04-2 and the second receiving wheel A05-2 to move away from or approach the movement path of the main transmission part A01. In this embodiment, the two guide kits A06 respectively guide the first receiving wheel A04-2 and the second receiving wheel A05-2 to move only in the vertical direction to adjust the first spacing L1 and the second spacing L2.

[0036] The specific structure of the guide kit A06 is quite diverse. Taking the guide kit A06 of the first receiving wheel A04-2 as an example, a protrusion can be set at the wheel center of the first receiving wheel A04-2, and then a guide clamping block can be fixed on the main transmission part A01. The protrusion can be placed in the clamping groove on the guide clamping block. When the first receiving wheel A04-2 moves, it can only move along the guide clamping groove. Any other structure that can limit the first receiving wheel A04-2 and the second receiving wheel A05-2 to move only on the required path can achieve the above effect.

[0037] Preferably, if Figure 2As shown, in this embodiment, the guide kit A06 includes a housing A06-1, a guide groove A06-2 opened on the housing A06-1, and the first receiving wheel A04-2 and the second receiving wheel A05-2 are both movably installed in the guide groove A06-2. The first receiving wheel A04-2 and the second receiving wheel A05-2 can be provided with a protruding block or a protruding roller at the wheel center, and then embedded in the guide groove A06-2 through the protruding block or the roller and restricted and guided by the guide groove A06-2.

[0038] Preferably, in this embodiment, two sets of electric drive kits A07 are also installed on the main transmission part A01, which are used to drive the first receiving wheel A04-2 and the second receiving wheel A05-2 away from or close to the main transmission part A01. Compared with manual adjustment means, the electric drive kit A07 has a more precise control over the first spacing L1 and the second spacing L2, and can output a stronger power when moving the first receiving wheel A04-2 and the second receiving wheel A05-2, and the adjustment speed is relatively faster.

[0039] Preferably, if Figure 2 As shown, the electric drive kit A07 includes a transmission rod A07-1, a telescopic drive rod A07-2 and a control kit, wherein one end of the transmission rod A07-1 is connected to the first receiving wheel A04-2 or the second receiving wheel A05-2, and the other end is connected to the extended section of the telescopic drive rod A07-2, and the control kit is used to control the telescopic amount of the extended section. On the one hand, the control of the first spacing L1 and the second spacing L2 under this structure is more accurate and the driving force provided is more stable; on the other hand, it can be matched with the above-mentioned guide kit A06 including a shell A06-1 and a guide groove A06-2 provided on the shell A06-1. Specifically, in this embodiment, the first receiving wheel A04-2 and the second receiving wheel A05-2 are provided with a protrusion at the wheel center, and the protrusion is embedded in the guide groove A06-2 and protrudes out of the shell A06-1, and the protruding part can be connected to one end of the transmission rod A07-1. This structure ensures that the electric drive kit A07 and the guide kit A06 can respectively drive and guide the first receiving wheel A04-2 and the second receiving wheel A05-2 without interfering with each other.

[0040] Embodiment 2: This embodiment provides a flip conveyor, such as Figure 3As shown, it mainly includes a fixed part B01, a flip part B02 and a flip drive kit B03. The flip conveyor is mainly arranged in the conveying system of the factory building, close to the location of the fire door. When a fire occurs and the fire door needs to be lowered, the flip part B02 can be rotated and lifted to form an avoidance. The flip conveyor adopts the relay transmission device described in Example 1, wherein the main transmission part A01 is installed in the fixed part B01, and the auxiliary transmission part A02 is installed in the flip part B02, wherein each transmission wheel of the main transmission wheel group A01-1 and the auxiliary transmission wheel group A02-1 is connected to a transmission roller, so the transmission chain A03 in the two wheel groups drives the rotation of the transmission wheel, and at the same time drives the operation of the transmission roller, and finally realizes the transmission of relay parts.

[0041] In the tilting conveyor, if it is necessary to avoid the fire door, Figure 3 For example, when the flip part B02 needs to rotate clockwise, that is, the secondary transmission part A02 needs to flip clockwise around the transition end A01-2, during the flipping process, on the transmission chain A03 connecting the main transmission wheel set A01-1 and the secondary transmission wheel set A02-1, the transmission chain A03 at the bottom will be tightened, while the transmission chain A03 at the top will be piled up and become loose. Therefore, the second spacing L2 can be reduced, and the transmission chain A03 originally temporarily stored in the bottom adjustment kit A05 can be released to prevent the bottom transmission chain A03 from being too tight and breaking; while at the same time, the first spacing L1 can be increased, and the excess loose transmission chain A03 can be temporarily stored in the top adjustment kit A04 to ensure that the top transmission chain A03 will not be too loose and fall off, thereby achieving coordination with the flipping workroom of the secondary transmission part A02. Therefore, the relay transmission device described in Example 1 can ensure that the transmission chain A03 placed between the flip part B02 and the fixed part B01 will not break or fall off. At the same time, it ensures that the overall weight of the flipping part B02 is small and there is no need to connect it with external components such as wires, which facilitates the flipping work.

[0042] When a fire occurs, the overturning conveyor equipped with the relay transmission device described in Example 1 can also realize that while the conveying work in the fixed part B01 is suspended, the overturning part B02 still maintains continuous transmission for a certain period of time, so as to transfer the relay parts stranded on the overturning part B02 back to the fixed part B01 and then lift the overturning part B02. This function reduces the damage of the relay parts that may occur during the subsequent overturning process, and also avoids the situation where the lighter relay parts fall to the drop point of the fire door and cause the fire door to fail to be lowered.

[0043] Preferably, if Figure 3As shown, the flip drive kit B03 includes a flip arm B03-1, a flip shaft B03-2 and a flip drive device B03-3. The flip shaft B03-2 passes through the fixed part B01 as a whole and protrudes on both sides of the fixed part B01; the flip drive device B03-3 is installed on the side wall of the fixed part B01 and is transmission-connected with the protruding part of the flip shaft B03-2; at the same time, two flip arms B03-1 are arranged on both sides of the fixed part B01, one end of each flip arm B03-1 is connected to the side wall of the flip part B02, and the other end is connected to the protruding part of the flip shaft B03-2. Therefore, when the flip drive device B03-3 drives the flip shaft B03-2 to rotate, it can also drive the flip arm B03-1 to rotate at the same time, and in this embodiment, the flip drive device B03-3 can drive the two flip arms B03-1 located on both sides of the fixed part B01 to rotate synchronously, ensuring the stable rotation of the flip part B02.

[0044] Preferably, if Figure 4 As shown, the flip arm B03-1 includes a first connecting section B03-1a, a second connecting section B03-1b, and a connecting section B03-1c connecting the first connecting section B03-1a and the second connecting section B03-1b, wherein the first connecting section B03-1a is connected to the flip shaft B03-2, and the second connecting section B03-1b is connected to the flip part B02. In this embodiment, the first connecting section B03-1a is connected to the protruding portion on the flip shaft B03-2, resulting in a gap between it and the fixed part B01, so it is necessary to provide the connecting section B03-1c to fill the gap to ensure that the second connecting section B03-1b can fit on both sides of the flip part B02.

[0045] Preferably, if Figure 3 As shown, in this embodiment, the overturning conveyor further includes an overturning guide B04, which includes a guide plate B04-1 installed on the side wall of the fixed part B01 and a guide protrusion B04-2 installed on the overturning arm B03-1, and the guide protrusion B04-2 is embedded in the overturning guide groove B04-1a on the guide plate B04-1. Under this structure, it is ensured that the overturning amount of the overturning part B02 will not be excessive, thereby causing damage to the overturning conveyor.

[0046] Embodiment 3: This embodiment provides a relay transmission system, in which the relay transmission device in embodiment 1 is used at one end connected to the processing mechanism, and the flip conveyor described in embodiment 2 is used in the middle. On the one hand, the relay transmission system of this embodiment can accurately move the two relays to the processing point of the next processing mechanism to ensure the smooth processing of the relays. On the other hand, the flip conveyor used in this relay transmission system is arranged near the location of the double-layer fire door, wherein the flip part B02 is placed at the drop point of the double-layer fire door. When a fire occurs in a workshop, it prevents the relay parts from continuing to transmit the relays to the workshop and can save some relay parts placed under the fire door, while ensuring the successful lowering of the fire door, thereby ensuring the safety of the rest of the workshops in the relay processing plant and reducing the loss of the relay processing plant.

[0047] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned implementation cases, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned implementation cases, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
