[0051] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-8 A circulating feeding device 100 according to a first aspect embodiment of the present invention is described.

[0052] like Figure 1 As shown, the circulating feeding device 100 according to the first aspect embodiment of the present utility model includes a first conveying mechanism 1, a second conveying mechanism 2, a first separation mechanism 3, and a second separation mechanism 4.

[0053] Specifically, the first conveying mechanism 1 is adapted to convey multiple jig assemblies 301 carrying the cover plate 302 of the battery, and the second conveying mechanism 2 is arranged along the first conveying mechanism 1 in a first direction. The second conveying mechanism 2 is adapted to convey the jig assemblies 301 after unloading the cover plate 302. In the description of this utility model, "multiple" means two or more.

[0054] For example, the second conveying mechanism 2 and the first conveying mechanism 1 can be arranged alternately along the vertical direction, the front-back direction, or the vertical direction; no limitation is made here, and they can be flexibly configured according to actual usage. In this application, the arrangement of the second conveying mechanism 2 and the first conveying mechanism 1 alternately along the vertical direction is used as an example for detailed explanation, i.e., the first direction is as follows... Figure 1The second conveying mechanism 2 is below the first conveying mechanism 1 in the up-down direction. Of course, the first conveying mechanism 1 can also convey the jig assembly 301 after the cover plate 302 is unloaded, and the second conveying mechanism 2 conveys the plurality of jig assemblies 301 bearing the cover plate 302 of the battery, which is not limited to the above definition, and the structures of the first conveying mechanism 1 and the second conveying structure can be the same. In this way, the second conveying mechanism 2 will not block the first conveying mechanism 1, making it easier to place the cover plate 302 of the battery on the plurality of jig assemblies 301 on the first conveying mechanism 1, reducing the difficulty of placing the cover plate 302, thereby improving the efficiency of placing the cover plate 302.

[0055] In combination with Figure 1 and Figure 2 , the first separation mechanism 3 and the second separation mechanism 4 are respectively arranged at both ends of the conveying direction of the first conveying mechanism 1, and the first separation mechanism 3 and the second separation mechanism 4 are respectively adapted to drive the jig assembly 301 to be movable between the first conveying mechanism 1 and the second conveying mechanism 2.

[0056] For example, in the example of Figure 1 and Figure 2 , the first conveying mechanism 1 conveys the jig assembly 301 in the left-right direction, the second conveying mechanism 2 conveys the jig assembly 301 in the left-right direction, and the conveying direction of the first conveying mechanism 1 is opposite to the conveying direction of the second conveying mechanism 2. The first separation mechanism 3 is located at the left end of the first conveying mechanism 1, and the second separation mechanism 4 is located at the right end of the first conveying mechanism 1. The first separation mechanism 3 drives the jig assembly 301 to move between the left end of the first conveying mechanism 1 and the left end of the second conveying mechanism 2, and the second separation mechanism 4 drives the jig assembly 301 to move between the right end of the first conveying mechanism 1 and the right end of the second conveying mechanism 2. Among them, the left end of the first conveying mechanism 1 is the unloading end, the first separation mechanism 3 drives the jig assembly 301 after unloading the cover plate 302 to move downward, the right end of the first conveying mechanism 1 is the feeding end, and the second separation mechanism 4 drives the jig assembly 301 after unloading the cover plate 302 to move upward, and then the cover plate 302 is placed on the jig assembly 301 after moving to the first separation mechanism 3.

[0057] The working process of the circulating feeding device 100 is roughly as follows:

[0058] First, a plurality of cover plates 302 are placed on the corresponding jig assemblies 301 by clamps (for example, two cover plates 302 are placed on the adjacent two jig assemblies 301 at the right end of the first conveying mechanism 1, that is, four cover plates 302 can be placed at the same time).

[0059] Secondly, the first conveying mechanism 1 conveys the cover plate 302 on the jig assembly 301 in the direction from right to left and processes the cover plate 302 (for example, flips, marks, etc.), and after the cover plate 302 is conveyed to the left end of the first conveying mechanism 1, the cover plate 302 is removed, and the jig assembly 301 at the left end of the first conveying mechanism 1 is the jig assembly 301 after the cover plate 302 is unloaded.

[0060] Next, the first separating mechanism 3 moves the jig assembly 301 after the cover plate 302 is unloaded at the left end a distance to the left, and after the jig assembly 301 at the left end is separated from the adjacent jig assembly 301 on the first conveying mechanism 1, the first separating mechanism 3 moves the jig assembly 301 after the cover plate 302 is unloaded at the left end downward to the left of the second conveying mechanism 2.

[0061] Subsequently, the first separating mechanism 3 moves the jig assembly 301 at the left end to the right to the left side of the second conveying mechanism 2, and the second conveying mechanism 2 conveys the jig assembly 301 after the cover plate 302 is unloaded in the direction from left to right. The jig assembly 301 moves to the right end on the second conveying mechanism 2 close to the second separating mechanism 4.

[0062] After that, the second separating mechanism 4 moves the jig assembly 301 to the right, and the jig assembly 301 is separated from the adjacent jig assembly 301 on the second conveying mechanism 2, and the second separating mechanism 4 moves the jig assembly 301 upward to the right end of the first conveying mechanism 1. The second separating mechanism 4 moves the jig assembly 301 to the left, and the jig assembly 301 moves to the first conveying mechanism 1. At this point, the complete movement of the jig assembly 301 on the first conveying mechanism 1 and the second conveying mechanism 2 is completed. The reciprocating action realizes the cycle feeding.

[0063] In this way, the first separating mechanism 3 and the second separating mechanism 4 enable the jig assembly 301 to be cyclically conveyed between the first conveying mechanism 1 and the second conveying mechanism 2, and the second conveying mechanism 2 can transport the jig assembly 301 after the cover plate 302 is unloaded to the loading end (for example, the right end of the first conveying mechanism 1) of the first conveying mechanism 1, thereby improving the working efficiency of the cyclic loading device 100, facilitating the continuous conveying of the cover plate 302 by the cyclic loading device 100, improving the conveying efficiency of the cover plate 302, and improving the processing efficiency of the cover plate 302. In addition, the automation performance of the cyclic loading device 100 is improved, and the use of the cyclic loading device 100 is facilitated. Moreover, compared with the prior art, the amount of work of the staff is also reduced, and the labor cost is saved. In addition, the second separating mechanism 4 can convey the jig assembly 301 after the cover plate 302 is unloaded on the second conveying mechanism 2 to the first conveying mechanism 1 for continuous use, facilitating the continuous placement of the cover plate 302 on the first conveying mechanism 1, and increasing the buffer of the cover plate 302 on the first conveying mechanism 1. In addition, the jig assembly 301 is continuously lowered and raised, the beat of the cyclic loading device 100 is improved, and the use functionality of the cyclic loading device 100 is improved.

[0064] According to the cyclic loading device 100 of the utility model, the jig assembly 301 can be cyclically conveyed between the first conveying mechanism 1 and the second conveying mechanism 2, the cover plate 302 can be continuously conveyed by the cyclic loading device 100, the conveying efficiency of the cover plate 302 is improved, and the processing efficiency of the cover plate 302 is improved. Moreover, the amount of work of the staff is also reduced. In addition, the second separating mechanism 4 can convey the jig assembly 301 after the cover plate 302 is unloaded on the second conveying mechanism 2 to the first conveying mechanism 1 for continuous use, facilitating the continuous placement of the cover plate 302 on the first conveying mechanism 1, and increasing the buffer of the cover plate 302 on the first conveying mechanism 1. Moreover, the beat of the cyclic loading device 100 is improved, and the use performance of the cyclic loading device 100 is improved.

[0065] According to some embodiments of the utility model, referring to Figure 1 、 Figure 5 and Figure 6 , the first separating mechanism 3 and the second separating mechanism 4 respectively include a base 31, a connecting assembly 32 and a first driving member 33, the base 31 is provided with at least one first sliding rail 3121, the first sliding rail 3121 extends along a first direction (for example, the up-down direction as shown in Figure 5 , the connecting assembly 32 is connected with the first sliding rail 3121, and the connecting assembly 32 is suitable for being separably matched with the jig assembly 301, and the first driving member 33 is connected with the connecting assembly 32 to drive the connecting assembly 32 to be movable along the extension direction of the first sliding rail 3121.

[0066] For example, in Figure 1 、 Figure 5And Figure 6 In the example of the first slide rail 3121 located at the front side of the base 31, the first slide rail 3121 extends along the up-down direction, the connecting assembly 32 is in sliding fit with the first slide rail 3121, and the upper end of the first driving member 33 is detachably connected with the lower end of the connecting assembly 32. The structure of the first separation mechanism 3 is the same as that of the second separation mechanism 4, and the first separation mechanism 3 and the second separation mechanism 4 can be symmetrically or asymmetrically distributed at both ends of the circulating feeding device 100.

[0067] In this way, under the action of the first driving member 33, the first driving member 33 drives the connecting assembly 32 to move the jig assembly 301 along the up-down direction together with the connecting assembly 32, and the jig assembly 301 is conveyed up and down, thereby effectively ensuring that the jig assembly 301 can circulate between the first conveying mechanism 1 and the second conveying mechanism 2, and the circulating feeding device 100 can continuously feed, thereby improving the use efficiency of the circulating feeding device 100. In addition, the first separation mechanism 3 and the second separation mechanism 4 are symmetrically arranged, which increases the buffer of the cover plate 302 and improves the beat of the circulating feeding device 100. It should be noted that the first slide rail 3121 can be provided with two first slide rails 3121, which are arranged in the left-right direction at intervals, thereby improving the stability of the assembly of the connecting assembly 32 and the first slide rail 3121, and thereby improving the stability of the up-down movement of the connecting assembly 32 and the jig assembly 301. According to different sizes of the cover plate 302, different sizes of the jig assembly 301 can be replaced, thereby improving the compatibility of the circulating feeding device 100 and the flexibility of use. The first driving member 33 can be a pneumatic cylinder.

[0068] According to some embodiments of the present application, referring to Figure 5 And Figure 6 The connecting assembly 32 comprises a first sliding block 321, a connecting block 322 and a second slide rail 323, the first sliding block 321 is movably connected to the first slide rail 3121, the connecting block 322 is connected to the side of the first sliding block 321 away from the first slide rail 3121, the connecting block 322 is connected to the first driving member 33, the second slide rail 323 is arranged on the side of the connecting block 322 away from the first sliding block 321, the second slide rail 323 extends along the conveying direction of the first conveying mechanism 1, and the second slide rail 323 is adapted to be detachably connected to the jig assembly 301.

[0069] For example, in Figure 5 And Figure 6In the example, the rear end of the first slider 321 is movably connected with the first slide rail 3121, the rear side of the connecting block 322 is connected with the front side of the first slider 321, the second slide rail 323 is located at the front side of the connecting block 322, the second slide rail 323 extends along the left-right direction, and the connecting block 322 is detachably connected with the first driving member 33. During the moving of the connecting assembly 32 up and down, the first driving member 33 is connected with the connecting block 322, and during the moving of the jig assembly 301 along the left-right direction, the first driving member 33 is separated from the connecting block 322. The jig assembly 301 is adapted to move along the extending direction of the second slide rail 323, i.e., the left-right direction.

[0070] In this way, according to the actual use, the jig assembly 301 can be separated from the connecting assembly 32, and the moving of the jig assembly 301 along the left-right direction is effectively ensured. The jig assembly 301 can also be matched with the connecting assembly 32, and the jig assembly 301 can move up and down with the connecting assembly 32, so that the cyclic moving of the jig assembly 301 is effectively ensured. In addition, the connecting assembly 32 has a simple structure and is easy to form and assemble, so that the production efficiency of the connecting assembly 32 is improved.

[0071] According to some embodiments of the present application, referring to Figure 5 and Figure 6 The base 31 comprises a base seat 311, a supporting seat 312 and a second driving member 313, the base seat 311 is provided with at least one third slide rail 3111, the supporting seat 312 is arranged on the base seat 311, the supporting seat 312 is provided with the first slide rail 3121, and the second driving member 313 is arranged at one end of the supporting seat 312. The second driving member 313 is used for driving the supporting seat 312 to be movable along the direction of the third slide rail 3111.

[0072] For example, in Figure 5 and Figure 6In the example, the lower end of the support base 312 is movably connected with the third slide rail 3111 on the base 311, the first slide rail 3121 is located on the front side of the support base 312, one end of the second driving member 313 is connected with the lower end of the support base 312 along one side in the left-right direction, and the first driving member 33 is connected with the support base 312. When the second driving member 313 drives the support base 312 to move, the connecting assembly 32, the jig assembly 301 and the first driving member 33 can move along the third slide rail 3111 together with the support base 312. In this way, during the lifting or lowering of the jig assembly 301, the connecting assembly 32 and the jig assembly 301 are driven to move together by the second driving member 313 to drive the support base 312, so that the jig assembly 301 is separated from the jig assembly 301 on the first conveying mechanism 1 or the second conveying mechanism 2, thereby avoiding the friction between the jig assembly 301 and the jig assembly 301 on the first conveying mechanism 1 or the second conveying mechanism 2 during the lifting or lowering of the jig assembly 301, so as to avoid the damage of the jig assembly 301, prolong the service life of the jig assembly 301, and further prolong the service life of the circulating feeding device 100. It should be noted that the second driving member 313 can be a pneumatic cylinder. The support base 312 is provided with a second slide block 3123 movably connected with the third slide rail 3111, which improves the smoothness of the reciprocating movement of the support base 312 on the third slide rail 3111.

[0073] Optionally, referring to Figures 4-6 , the third slide rail 3111 extends along the conveying direction of the first conveying mechanism 1. For example, in the example of Figures 4-6 , the third slide rail 3111 extends in the left-right direction. In this way, when the second driving member 313 drives the support base 312 to make the second slide rail 323 merge with the first conveying mechanism 1 (for example, the fourth slide rail 11 of the first conveying mechanism 1) or the second conveying mechanism 2 (for example, the fourth slide rail 11 of the second conveying mechanism 2), the dislocation is avoided, so that the jig assembly 301 on the second separating mechanism 4 can be smoothly conveyed along the first conveying mechanism 1, and the jig assembly 301 on the first separating mechanism 3 can be smoothly conveyed along the second conveying mechanism 2, thereby improving the smoothness of the conveying, and further enabling the circulating feeding device 100 to be used normally for a long time.

[0074] According to some embodiments of the present application, referring to Figure 2 , Figure 3 and Figure 5 , the side of the base 311 away from the first conveying mechanism 1 is provided with a first limiting member 3112. For example, in Figure 2 , Figure 3 and Figure 5In the example, the first limiting piece 3112 is located on the side of the base 311 away from the second driving piece 313. Thus, the first limiting piece 3112 can limit the support seat 312, easily control the distance of the support seat 312 moving away from the first conveying mechanism 1, and avoid the support seat 312 sliding off the third sliding rail 3111, thereby improving the distance precision of the support seat 312 moving on the third sliding rail 3111 and facilitating the control of the moving distance of the support seat 312. The side of the first limiting piece 3112 facing the support seat 312 is provided with a buffer pad (not shown in the figure), which can buffer the impact force of the support seat 312 on the first limiting piece 3112, avoid the damage of the support seat 312 and the first limiting piece 3112, and prolong the service life of the base 31.

[0075] According to some embodiments of the present application, referring to Figure 7 and Figure 8 , the side of the support seat 312 away from the second driving piece 313 is provided with a second limiting piece 3122 to limit the movement of the connecting block 322 relative to the first sliding rail 3121.

[0076] For example, in the example of Figure 7 and Figure 8 , the second limiting piece 3122 is located on the upper end of the support seat 312, and the front end of the second limiting piece 3122 is in separable contact with the upper side of the connecting block 322. During the process of the second driving piece 313 driving the connecting assembly 32 to move upward, the second limiting piece 3122 limits the connecting block 322 of the connecting assembly 32, avoids the connecting assembly 32 driving the jig assembly 301 to continue moving upward, easily controls the second sliding rail 323 of the second separating mechanism 4 and the fourth sliding rail 11 of the first conveying mechanism 1 on the same axis, thereby facilitating the jig assembly 301 to smoothly move from the second separating mechanism 4 to the first conveying mechanism 1, and enabling the circulating feeding device 100 to be normally used for a long time.

[0077] According to some embodiments of the present application, referring to Figure 5 , the circulating feeding device 100 further comprises a third driving piece 5 and a fourth driving piece 6, the third driving piece 5 is connected with the connecting assembly 32 of the first separating mechanism 3, and the third driving piece 5 is used to drive the jig assembly 301 after the unloading cover plate 302 to move to the second conveying mechanism 2. The fourth driving piece 6 is connected with the connecting assembly 32 of the second separating mechanism 4, and the fourth driving piece 6 is used to drive the jig assembly 301 bearing the cover plate 302 to move to the first conveying mechanism 1.

[0078] For example, in the example of Figure 5In the example, the third driving member 5 is located at the left side of the first separating mechanism 3, and the fourth driving member 6 is located at the right side of the second separating mechanism 4. The piston rod of the third driving member 5 (for example, a cylinder) pushes the jig assembly 301 on the first separating mechanism 3 to move to the second conveying mechanism 2, and the piston rod of the fourth driving member 6 (for example, a cylinder) pushes the jig assembly 301 on the second separating mechanism 4 to move to the first conveying mechanism 1.

[0079] In this way, by the third driving member 5 and the fourth driving member 6, the jig assembly 301 is facilitated to move in the left-right direction, so that the cover plate 302 can continue to move to the next processing procedure with the jig assembly 301, thereby ensuring the processing of the cover plate 302. Moreover, the circulating feeding device 100 can also be circulated, thereby improving the use performance of the circulating feeding device 100. It should be noted that the third driving member 5 and the fourth driving member 6 can be long-range cylinders or electric cylinders. When the third driving member 5 and the fourth driving member 6 are electric cylinders, the positions of the jig assembly 301 can be accurately controlled. For the switching of the cover plate model and the change of the size of the jig assembly 301, the sliding stability can be improved, and the operation rate of the circulating feeding device 100 can be improved.

[0081] For example, the first buffer 7 and the second buffer 8 are provided in the following cases: first, the first buffer 7 is provided on the connecting assembly 32 of the first separating mechanism 3. Second, the second buffer 8 is provided on the connecting assembly 32 of the second separating mechanism 4. Third, the first buffer 7 is provided on the connecting assembly 32 of the first separating mechanism 3, and the second buffer 8 is provided on the connecting assembly 32 of the second separating mechanism 4.

The second buffer 8 is located on the right side of the second separation mechanism 4, and the second buffer 8 is located above the fourth driving member 6. In this way, when the jig assembly 301 moves onto the first separation mechanism 3, the first buffer 7 can buffer the impact force of the jig assembly 301 on the first separation mechanism 3, so as to avoid damage to the jig assembly 301. When the jig assembly 301 moves onto the second separation mechanism 4, the second buffer 8 can buffer the impact force of the jig assembly 301 on the second separation mechanism 4, so as to avoid damage to the jig assembly 301, thereby prolonging the service life of the jig assembly 301. It should be noted that the first buffer 7 and the second buffer 8 can be buffer air cylinders. The first buffer 7 and the second buffer 8 retract after buffering the jig assembly 301.

[0082] Optionally, referring to Figure 4 and Figure 5 , the first conveying mechanism 1 and the second conveying mechanism 2 respectively include a fourth sliding rail 11 and a first bottom plate 12, one side of the fourth sliding rail 11 is connected with the first bottom plate 12, the other side of the fourth sliding rail 11 is detachably matched with the jig assembly 301, and the fourth sliding rail 11 extends along the left-right direction. The circulating feeding device 100 further includes a support 9, the support 9 includes a support column 91 and a second bottom plate 92, the first conveying mechanism 1 and the second conveying mechanism 2 are respectively connected to the second bottom plate 92 through the first bottom plate 12, and the upper end of the support column 91 is connected with the second bottom plate 92. In this way, the jig assembly 301 is facilitated to move on the first conveying mechanism 1 or the second conveying mechanism 2 along the fourth sliding rail 11, and the cover plate 302 on the jig assembly 301 is facilitated to be processed. In addition, the first conveying mechanism 1 and the second conveying mechanism 2 are facilitated to be connected with the support 9 through the second bottom plate 92, and the stability of the first conveying mechanism 1 and the second conveying mechanism 2 is improved. Moreover, the support column 91 has a supporting effect on the second bottom plate 92, and the stability of the first conveying mechanism 1 or the second conveying mechanism 2 is further improved, so that the stability of the circulating feeding device 100 is improved.

[0083] According to the welding machine 200 of the second aspect of the present application, referring to Figure 9 and Figure 10 , the welding machine 200 includes the circulating feeding device 100 according to the first aspect of the present application.

[0084] According to the welding machine 200 of the present application, by adopting the above-mentioned circulating feeding device 100, the working efficiency of the welding machine 200 is improved.

[0085] According to some embodiments of the present application, referring to Figure 9 and Figure 11 , the welding machine 200 includes a first overturning mechanism 201, a code marking mechanism 202 and a dust removal mechanism 203. ​

[0086] Specifically, the first turnover mechanism 201 is arranged in the conveying direction of the first conveying mechanism 1, and is adapted to turn over the cover plate 302 carried on the jig assembly 301. The dust removal mechanism 203 is arranged in the conveying direction of the first conveying mechanism 1, and is located downstream of the first turnover mechanism 201. The coding mechanism 202 is arranged on the side of the dust removal mechanism 203 away from the first conveying mechanism 1, and is opposite to the dust removal mechanism 203 in the first direction, and the light emitted by the coding mechanism 202 passes through the dust removal mechanism 203 and irradiates on the cover plate 302 located on the first conveying mechanism 1.

[0087] For example, in the example of 9, Figure 11 and Figure 12 The dust removal mechanism 203 is located on the left side of the first turnover mechanism 201, and the coding mechanism 202 and the dust removal mechanism 203 are respectively located on the front and back sides of the first conveying mechanism 1, and the part of the coding mechanism 202 emitting light is located above the dust removal mechanism 203. When the cover plate 302 moves with the jig assembly 301 on the first conveying mechanism 1 to the first turnover mechanism 201, the first turnover mechanism 201 turns over the cover plate 302 by 90°. Then, the cover plate 302 continues to move to the left, and when it moves to the dust removal mechanism 203, the light emitted by the coding mechanism 202 passes through the dust removal mechanism 203 and irradiates on the cover plate 302, forming a two-dimensional code and a bar code, and in the process of coding, the dust removal mechanism 203 removes dust. Then the cover plate 302 continues to move to the left.

[0088] In this way, the cover plate 302 realizes the functions of feeding, turning over and coding on the circulating feeding device 100, increases the practicability and functionality, and improves the processing efficiency of the cover plate 302. Moreover, the dust removal mechanism 203 improves the cleanliness in the coding process and improves the cleanliness of the environment. It should be noted that the plurality of cover plates 302 can be simultaneously processed by feeding, turning over and coding. The welding machine 200 further comprises a plurality of first sensing members 204, second sensing members 205 and a second turnover mechanism 206, which are arranged in the conveying direction of the first conveying mechanism 1, and the first sensing members 204 are located upstream of the first turnover mechanism 201. The first sensing members 204 are provided with four first sensing members 204, which are used to detect whether the jig assembly 301 carries the cover plate 302, that is, to detect whether the feeding is performed. The second sensing member 205 is located between the first turnover mechanism 201 and the dust removal mechanism 203, and is used to detect whether the cover plate 302 is turned over to the appropriate position. The second turnover mechanism 206 is located downstream of the dust removal mechanism 203, and turns over the cover plate 302 by 180° after coding, which is convenient for subsequent processing of the cover plate 302. It should be noted that the first sensing member 204 can be a sensor, and the second sensing member 205 can be a fiber optic sensor.

[0089] Optionally, with reference to Figure 6 and Figure 13 The jig assembly 301 comprises a third sliding block 3011, a mounting plate 3012, and a jig 3013 located above the mounting plate 3012, the jig 3013 being connected with the mounting plate 3012, and the third sliding block 3011 being connected with the rear side of the mounting plate 3012. The jig assembly 301 is adapted to be separably moved on the second sliding rail 323 and the fourth sliding rail 11 by the third sliding block 3011. The upper side of the jig 3013 is formed with a first groove 3013a penetrating through the jig 3013 in the front-rear direction, and a plurality of support blocks 3013b are respectively formed on two side walls opposite in the left-right direction of the first groove 3013a, the plurality of support blocks 3013b being arranged at intervals in the front-rear direction, and a second groove 3013c being jointly defined between two support blocks 3013b opposite in the left-right direction. When the cover plate 302 is fed, the cover plate 302 is inserted into the second groove 3013c, and the thickness direction of the cover plate 302 is perpendicular to the up-down direction. After the cover plate 302 is flipped by 90° by the first flipping mechanism 201, the cover plate 302 is placed on the upper side of the plurality of support blocks 3013b, the side wall of the cover plate 302 abutting against the side wall of the first groove 3013a, and the thickness direction of the cover plate 302 being parallel to the up-down direction. In this way, the jig 3013 is moved on the second sliding rail 323 and the fourth sliding rail 11 by the third sliding block 3011 and the mounting plate 3012, improving the convenience of moving the jig 3013. In addition, the jig 3013 can horizontally or vertically place the cover plate 302, facilitating the placement of the cover plate 302 according to different use conditions, and improving the flexibility of using the jig 3013. In addition, the design of the jig 3013 can realize the functions of feeding, flipping, and code printing of the cover plate 302 on the circulating feeding device 100, increasing the practicability and functionality of the circulating feeding device 100.

[0090] The working process of the circulating feeding device 100 is as follows:

[0091] Firstly, a plurality of cover plates 302 are placed on the jig 3013 of the corresponding jig assembly 301 by the clamp, wherein the cover plate 302 is inserted into the second groove 3013c.

[0092] Secondly, after the first sensing member 204 detects the loading of the cover plate 302, the piston rod of the fourth driving member 6 pushes the mounting plate 3012 of the jig assembly 301 on the first conveying mechanism 1, so that the jig assembly 301 on the first conveying mechanism 1 conveys the cover plate 302 in the direction from right to left, and processes the cover plate 302. The cover plate 302 sequentially passes through the first turnover mechanism 201 (the first turnover mechanism 201 turns the cover plate 302 by 90°, and the cover plate 302 is horizontally placed on the support block 3013b at the first groove 3013a), the second sensing member 205 (the second sensing member 205 detects whether the cover plate 302 is turned to the position for code printing), the code printing mechanism 202 and the dust removal mechanism 203 (the code printing mechanism 202 prints two-dimensional code and bar code on the cover plate 302, and the dust removal mechanism 203 removes dust during code printing), the second turnover mechanism 206 (the second turnover mechanism 206 turns the cover plate 302 by 180°, that is, turns the two-dimensional code and bar code of the cover plate 302 to the back surface), and after the cover plate 302 is conveyed to the left end of the first conveying mechanism 1, the cover plate 302 is removed, and at this time, the jig assembly 301 at the left end of the first conveying mechanism 1 is the jig assembly 301 after the cover plate 302 is unloaded.

[0093] Then, the second driving member 313 drives the support seat 312 of the first separation mechanism 3 to drive the connecting assembly 32 and the jig assembly 301 at the left end after the cover plate 302 is unloaded to move leftward by a distance, the support seat 312 is in contact with the buffer pad on the second limiting member 3122, after the jig assembly 301 at the left end is separated from the adjacent jig assembly 301 on the first conveying mechanism 1, the first driving member 33 drives the connecting assembly 32 to drive the jig assembly 301 at the left end after the cover plate 302 is unloaded to move downward along the first sliding rail 3121, and moves to the left of the second conveying mechanism 2.

[0094] Subsequently, the second driving member 313 drives the support seat 312 to drive the connecting assembly 32 and the jig assembly 301 at the left end to move rightward, and moves to the left side of the second conveying mechanism 2, the second sliding rail 323 of the connecting assembly 32 on the first separation mechanism 3 coincides with the fourth sliding rail 11 of the second conveying mechanism 2 (thereafter, the first driving member 33 can be continuously connected or separated from the connecting block 322). The piston rod of the third driving member 5 drives the jig assembly 301 on the first separation mechanism 3, and pushes the jig assembly 301 on the second conveying mechanism 2 to convey the jig assembly 301 after the cover plate 302 is unloaded in the direction from left to right. The jig assembly 301 moves to the right end close to the second separation mechanism 4 on the second conveying mechanism 2.

[0095] Afterwards, the second driving member 313 drives the support seat 312 of the second separating mechanism 4 to drive the connecting assembly 32 and the jig assembly 301 to move rightwards, the jig assembly 301 is separated from the jig assembly 301 adjacent to the second conveying mechanism 2, the first driving member 33 drives the connecting assembly 32 to drive the jig assembly 301 to move upwards to the right end of the first conveying mechanism 1, and the second limiting member 3122 limits the connecting assembly 32. The second driving member 313 drives the support seat 312 of the second separating mechanism 4 to drive the connecting assembly 32 and the jig assembly 301 to move leftwards, so that the jig assembly 301 moves to the first conveying mechanism 1. At this time, the complete movement of the jig assembly 301 on the first conveying mechanism 1 and the second conveying mechanism 2 is completed. The reciprocating action is used to realize the cyclic feeding.
