Description

Technical Field

[0001] This application relates to the technical field of motor accessory transportation, and in particular to a buffer tray for workpiece transportation. Background Art

[0002] During the production process of motor accessories, it is usually necessary to transfer the accessories between different workstations. For cylindrical workpieces (such as motor stators), during transportation, the existing method is to directly place multiple stators in a transport box, and then place the transport box on a transport trolley for transportation. At the same time, a clamping structure for preventing the stator from rolling in the horizontal direction is provided in the transport box. When using this method for transportation, only the staff needs to place the stator in the transport box, and then clamp the stator through the clamping structure. It is simple and convenient to use, can transport multiple stators at one time, and effectively reduces the probability of the stator rolling in the horizontal direction.

[0003] However, in the actual use process, the trolley is inevitably jolted during movement. Since there is only a structure for clamping the stator in the horizontal direction in the transport box, the stator is likely to vibrate in the vertical direction in the transport box when the trolley jolts. When the vibration amplitude of the stator in the vertical direction is relatively large, it is more likely to cause the stator to break away from the clamping of the clamping structure, resulting in the stator falling out of the transport box and affecting the transportation quality of the stator. Summary of the Utility Model

[0004] In order to effectively reduce the vibration in the vertical direction during transportation, thereby preventing the stator from falling out of the transport box and achieving the purpose of improving the transportation quality of the stator, this application provides a buffer tray for workpiece transportation.

[0005] A buffer tray for workpiece transportation provided by this application adopts the following technical solutions:

[0006] A buffer tray for workpiece transportation includes a tray. A placement groove for placing a transport box is provided on the tray. A surrounding plate is detachably connected to the tray. A placement cavity is formed by enclosing between the surrounding plate and the tray. The transport box is located in the placement cavity. A top cover for blocking the opening of the placement cavity is provided on the surrounding plate. A buffer structure for providing buffering for the whole device is also provided on the tray.

[0007] By adopting the above technical solutions, during use, the transport box is placed on the tray. After the staff places the workpiece in the transport box, the surrounding plate can be connected to the tray, and the top cover can be buckled on the top of the surrounding plate. Thus, through the combined use of the surrounding plate and the top cover, the transport box is limited, reducing the situation of the transport box falling off the tray. At the same time, the buffer structure is combined to provide a buffering force for the whole device, thereby reducing the vibration force of the workpiece in the vertical direction, and further reducing the situation that the workpiece is likely to fall out of the transport box, improving the transportation quality of the workpiece.

[0008] Preferably, the buffer structure includes a base disposed under the tray, support feet fixed on the tray, and shock absorbers disposed between the support feet and the base. There are a plurality of the support feet, and the plurality of support feet are evenly spaced. The number of the bases and the support feet is the same and they correspond to each other one by one. An embedding groove is formed on the base, and one end of the support foot away from the tray is inserted and matched with the embedding groove. The shock absorber is located between the bottom wall of the embedding groove and the end face of the support foot.

[0009] By adopting the above technical solution, during use, the support feet are guided by the embedding grooves, so that the support feet are slidably inserted into the embedding grooves. At the same time, the shock absorbers provide shock absorption effects for the support feet, thereby reducing the vibration of the support feet in the vertical direction. Then, through the cooperation of a plurality of shock absorbers, the buffer force can be provided for the whole device.

[0010] Preferably, a hollowing groove is formed on the tray at the position corresponding to the support feet, and an avoidance groove is formed on the base at the position corresponding to the embedding grooves. One end of the shock absorber passes through the support foot and is fixed in the hollowing groove by a first nut, and the other end of the shock absorber passes through the base and is fixed in the avoidance groove by a second nut. The first nut abuts against the bottom wall of the hollowing groove, and the second nut abuts against the bottom wall of the avoidance groove.

[0011] By adopting the above technical solution, during use, due to the settings of the hollowing groove and the avoidance groove, on the one hand, the overall weight of the tray is reduced, and on the other hand, it is convenient to install the shock absorbers.

[0012] Preferably, a first reinforcing rib is fixed on the side wall of the hollowing groove.

[0013] By adopting the above technical solution, during use, by setting the first reinforcing rib, the structural strength at the position of the hollowing groove is improved, thereby indirectly improving the structural strength of the tray.

[0014] Preferably, a connecting plate is disposed between several bases arranged along the length direction of the tray, and the connecting plate fixedly connects several bases arranged along the length direction of the tray together.

[0015] By adopting the above technical solution, during use, several horizontally arranged bases are connected together by the connecting plate, thereby dividing a plurality of bases into several groups. On the one hand, it is convenient for workers to assemble the bases, the tray and the shock absorbers, and on the other hand, the contact area between the bases and the bottom surface is increased, so that after the bases are installed on the tray, the whole device is more stable in use.

[0016] Preferably, the support foot is arranged in a necking shape from the end close to the tray to the end close to the base, and the embedding groove is arranged in a flaring shape from the bottom wall to the opening direction.

[0017] By adopting the above technical solution, during use, the supporting feet and the embedding grooves set by shape matching increase the convenience when the supporting feet and the embedding grooves are combined.

[0018] Preferably, a weight-reducing groove is formed in the tray.

[0019] By adopting the above technical solution, during use, by forming the weight-reducing groove, the weight of the tray is reduced, thereby reducing the overall weight of the device and making it more convenient to use.

[0020] Preferably, a first insertion slot for inserting one end of the surrounding plate is formed at the bottom of the placement groove, and a second insertion slot for inserting the other end of the surrounding plate is formed in the top cover.

[0021] By adopting the above technical solution, through the combined use of the first insertion slot and the second insertion slot, a convenient detachable connection between the surrounding plate, the tray and the top cover is realized, which is beneficial to use.

[0022] Preferably, a first clamping structure for clamping the surrounding plate on the tray is arranged on the tray, and a second clamping structure for clamping the top cover on the surrounding plate is arranged on the top cover.

[0023] By adopting the above technical solution, during use, after the surrounding plate, the top cover and the tray are combined together, through the combined use of the first clamping structure and the second clamping structure, the clamping and fixing of the surrounding plate and the top cover are realized, thereby reducing the situation that the surrounding plate and the top cover are separated from the tray, and indirectly improving the transportation quality of the workpiece.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By placing the transportation frame on the tray and connecting the surrounding plate and the top cover to the tray, the limit of the transportation frame is formed, effectively reducing the situation that the transportation frame is separated from the tray. At the same time, in cooperation with the buffer structure, a buffer force is provided for the whole device, reducing the vibration of the whole device in the vertical direction, thereby reducing the situation that the workpiece is separated from the clamping structure, and further improving the transportation quality of the workpiece;

[0026] 2. Through the arrangement of the supporting feet and the embedding grooves, and through the matching relationship of the shapes of the supporting feet and the embedding grooves, the guiding of the vertical sliding of the supporting feet is realized. At the same time, the vibration of the supporting feet is reduced by a plurality of shock absorbers, thereby reducing the vibration of the whole device in the vertical direction;

[0027] 3. Through the arrangement of the hollow-out groove, the first reinforcing rib and the weight-reducing groove on the tray, while reducing the weight of the tray, the structural strength of the tray is also improved. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0036] The following further elaborates on the present application in conjunction with the attached Figure 1 - attached Figure 7 drawings.

[0037] Embodiment 1 of the present application discloses a buffer tray for workpiece transportation.

[0038] Embodiment 1:

[0039] Refer to Figure 1 and Figure 2, a buffer tray for workpiece transportation, including a rectangular tray 1 placed horizontally. A placement groove 11 for placing a transportation frame is opened on the upper surface of the tray 1. A first slot 14 is opened on the peripheral side of the bottom wall of the placement groove 11. A surrounding plate 2 and a top cover 3 are arranged on the tray 1. The bottom end of the surrounding plate 2 is inserted and embedded in the first slot 14. The top cover 3 is located above the surrounding plate 2. A second slot is opened on the bottom surface of the top cover 3 for embedding the top end of the surrounding plate 2. After the surrounding plate 2 is connected to the tray 1, a placement cavity is enclosed between the surrounding plate 2 and the tray 1. The transportation frame is located in the placement cavity. The top cover 3 is used to block the top opening of the placement cavity. In addition, a flexible buffer layer can be adhesively fixed to the bottom of the top cover 3 to prevent the top cover 3 from directly contacting the workpiece. The flexible buffer layer can be a flexible rubber pad.

[0040] Refer to Figure 1 and Figure 2 , during use, insert the bottom end of the surrounding plate 2 into the first slot 14. The friction between the inner wall of the first slot 14 and the side wall of the surrounding plate 2 reduces the situation of the surrounding plate 2 disengaging from the first slot 14. Then, buckle the top cover 3 on the upper end of the surrounding plate 2, so that the top end of the surrounding plate 2 is inserted into the second slot. The friction between the inner wall of the second slot and the side wall of the surrounding plate 2 reduces the situation of the surrounding plate 2 disengaging from the second slot. In this way, the assembly of the surrounding plate 2, the tray 1 and the top cover 3 can be realized, so that the placement cavity becomes a closed space, and then the transportation frame is limited by the closed placement cavity, reducing the situation of the transportation frame disengaging from the tray 1 during transportation.

[0041] Refer to Figure 2 and Figure 3 , a buffer structure 4 is arranged below the tray 1. The buffer structure 4 is used to provide a buffer force in the vertical direction for the whole device. The buffer structure 4 is composed of a base 41, support feet 42 and shock absorbers 43. The support feet 42 are integrally formed on the bottom surface of the tray 1. There are multiple support feet 42, and the multiple support feet 42 are evenly spaced on the bottom surface of the tray 1. In this embodiment, the support feet 42 are preferably set to nine. The nine support feet 42 are evenly divided into three groups. Each group includes three support feet 42, and the three groups of support feet 42 are evenly spaced along the width direction of the tray 1. The three support feet 42 in each group of support feet 42 are evenly spaced along the length direction of the tray 1.

[0042] Refer to Figure 2 and Figure 3, the number of the base 41 and the shock absorber 43 is the same as that of the supporting feet 42, and their installation positions correspond one by one. A slot 411 is formed in the base 41, and the slot 411 is in plug-in fit with the bottom end of the supporting foot 42. Meanwhile, in order to facilitate the connection between the supporting foot 42 and the base 41, the supporting foot 42 is arranged with a gradually narrowing opening from the end close to the tray 1 to the bottom end of the supporting foot 42, and the opening of the slot 411 is arranged with a gradually widening opening from the bottom wall to the opening direction, that is, the side wall of the supporting foot 42 and the inner side wall of the slot 411 are both inclined and parallel to each other.

[0043] Refer to Figure 3 and Figure 4 , the shock absorber 43 is located between the bottom wall of the slot 411 and the bottom end face of the supporting foot 42. In this embodiment, the shock absorber 43 is preferably set as a double-headed external screw elastic rubber shock absorber 43. A hollow slot 12 is formed in the tray 1 at the position corresponding to the supporting foot 42, and an avoidance slot 412 is formed in the base 41 at the position corresponding to the slot 411. The upper screw end of the shock absorber 43 passes through the supporting foot 42 and is threadedly connected with a first nut located in the hollow slot 12, and the lower screw end of the shock absorber 43 passes through the bottom wall of the slot 411 and is threadedly connected with a second nut located in the avoidance slot 412.

[0044] Refer to Figure 3 and Figure 4 , during use, the bottom end face of the first nut abuts against the bottom wall of the hollow slot 12, and the top end face of the second nut abuts against the bottom wall of the avoidance slot 412. After the shock absorber 43 is connected with the first nut and the second nut, the assembly among the shock absorber 43, the base 41 and the tray 1 can be realized through the cooperation of the first nut and the second nut, so as to provide a vertical buffering force for the tray 1 through the shock absorber 43, thereby realizing the reduction of the vibration force of the whole device in the vertical direction.

[0045] Refer to Figure 3 and Figure 4 , in addition, in order to facilitate the assembly between the base 41 and the tray 1, in this embodiment, a connecting plate 44 is arranged between the three bases 41 arranged along the length direction of the tray 1. The connecting plate 44 is used to connect and fix the three bases 41 together. The connecting plate 44 and the base 41 are integrally formed. Then, through the arrangement of the connecting plate 44, the nine bases 41 are evenly divided into three groups, and a forklift slot is formed between adjacent two groups of bases 41. The setting of the forklift slot facilitates the staff to carry the whole device through a forklift.

[0046] Refer to Figure 3 and Figure 5, a first reinforcing rib 5 is integrally formed on the inner wall of the hollow groove 12, and a second reinforcing rib 6 is integrally formed on the side wall of the first slot 14. During use, the structural strength of the entire tray 1 is increased through the settings of the first reinforcing rib 5 and the second reinforcing rib 6; at the same time, a weight-reducing groove 13 is provided on the bottom wall of the tray 1. Through the settings of the weight-reducing groove 13 and the hollow groove 12, the weight of the tray 1 can be effectively reduced, making it more convenient for the staff to use.

[0047] The implementation principle of the embodiment of this application is as follows: During use, first place the transport frame on the tray 1, and then the staff puts the workpieces to be transported into the transport frame one by one. After placing is completed, then fasten the side plate 2 and the top cover 3 on the tray 1 to form the limit and protection for the transport frame. After that, the tray 1 equipped with the workpieces can be placed on the transport trolley. During the transportation process, through the cooperation of the support feet 42, the base 41, and the shock absorbers 43, a buffering force in the vertical direction is provided for the entire device, thereby reducing the vertical vibration caused by the bumping of the trolley during transportation, and further improving the transportation quality of the workpieces.

[0048] The difference between Embodiment 2 and Embodiment 1 is that:

[0049] Refer to Figure 6 , a first clamping structure 7 is further provided on the tray 1. The first clamping structure 7 is used to clamp and fix the side plate 2 on the tray 1. A second clamping structure 8 is provided on the top cover 3. The second clamping structure 8 is used to clamp the top cover 3 on the side plate 2. During use, through the combined use of the first clamping structure 7 and the second clamping structure 8, the connection stability between the tray 1, the side plate 2, and the top cover 3 is improved, thereby reducing the situation where the side plate 2 and the top cover 3 are separated from the tray 1 during transportation.

[0050] Refer to Figure 6 and Figure 7 , both the first clamping structure 7 and the second clamping structure 8 can be implemented by spring pins, buckles, or clamping blocks. In this embodiment, both the first clamping structure 7 and the second clamping structure 8 are set as clamping blocks. The connection structure of the second clamping structure 8 is similar to that of the first clamping structure 7. Therefore, taking the first clamping structure 7 as an example: The first clamping structure 7 includes a clamping convex block integrally formed on the side wall of the first slot 14. There are multiple clamping convex blocks, and the multiple clamping convex blocks are evenly distributed at the periphery of the first slot 14. Corresponding clamping grooves for embedding the clamping convex blocks are provided on the side plate 2; during use, insert the side plate 2 into the first slot 14, and through the clamping convex blocks being clamped and embedded into the clamping grooves, the clamping and fixing of the side plate 2 can be achieved, which is simple and convenient to use.

[0051] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
