[0002] A relay is an electrical control device. When the change of input quantity reaches the specified requirement, it causes the controlled quantity to undergo a predetermined step change in the electrical output circuit. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit); it is usually used in automated control circuits. It is actually an "automatic switch" that uses a small current to control the operation of a large current; it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit.

[0015] A bracket loader comprises a relay bracket internal suction type moving head.

[0016] The beneficial effects of the present invention are: In view of the defects and shortcomings of the prior art, the present invention independently develops and designs a relay bracket internal suction moving head and a bracket loader which adopts flexible contact fitting and internal suction methods to realize automatic moving of the relay bracket after being fixed, and at the same time has a pre-compression and leveling function before material picking. While realizing automatic material picking, the deformation of the relay bracket is effectively reduced, the flatness during material picking is ensured, and the material picking accuracy is improved.

[0017] The present invention is applied to the field of automatic assembly of relay brackets, and belongs to the core mechanism of the automatic feeding machine of relay brackets, and its function is to realize the automatic picking and placing of relay brackets. Based on the rectangular frame structure of the relay bracket and its material characteristics, the picking and placing method of the present invention is significantly different from the traditional picking method. The present invention adopts an internal side suction method to fix the relay bracket during picking, which can effectively reduce the deformation problem of the side of the relay bracket during the picking and placing process. At the same time, the pre-pressing and leveling of the relay bracket is also realized synchronously before picking, which effectively ensures the surface flatness of the relay bracket before picking, and avoids the difference in angles of different sides of the relay bracket caused by unevenness when inserting into the relay bracket, thereby reducing the problem of abrasion and deformation of the inner wall when the material is inserted into the relay bracket, and the precise flatness of the material picking helps to improve the accuracy of subsequent relay component assembly. Specifically, the present invention as a whole comprises a connecting support assembly and a material picking assembly. The connecting support assembly is used for bearing support and is connected to the driving mechanism of the material loader. It is driven by the power of the driving mechanism to move in the horizontal plane and in the vertical direction so as to achieve transfer between different workstations of the material loader. A plurality of groups of material picking assemblies are arranged at intervals at the bottom of the support of the connecting support assembly, which are used for automatically picking up and placing a plurality of relay brackets at the same time to improve the efficiency of single picking and placing. The material picking assembly of the present invention uses a bearing frame as a connecting structure. A pressure plate is horizontally arranged at the bottom of the bearing frame, and a through groove is opened on the pressure plate that passes through from top to bottom. A material picking cylinder is vertically arranged on the top plate of the bearing frame, and the output end of the material picking cylinder It is arranged downward and connected with a material picking seat, and the material picking cylinder drives the material picking seat to move up and down through the through slot; in the material picking process, the support drives multiple groups of material picking components to synchronously descend and approach the material station, so that the pressure plate presses the flat relay bracket from above, completes the pre-compression and leveling of the relay bracket, and can effectively ensure the position stability of the relay bracket during the process of the material picking seat extending into the relay bracket; after the pre-compression of the relay bracket is completed, the material picking cylinder drives the material picking seat to pass through the through slot and continue to extend downward into the relay bracket, and after the relay bracket is fixed from the side of the relay bracket through the adsorption piece inserted inside the material picking seat, the support drives multiple groups of material picking components to move upward to realize material movement.The special thing is that the adsorption piece of the present invention is flexibly and movably inserted into the material picking seat body. As an embodiment, the adsorption piece of the present invention is a first suction block of a cylindrical structure, and the first suction block is a magnetic block, which can adsorb and fix a relay bracket made of metal. The material picking seat body of the present invention is horizontally provided with a plurality of first limiting grooves, and the outer end of the first limiting groove extends to the outer side wall of the material picking seat body for slidably inserting the first suction block. The first limiting slide seat connected to the inner end of the first suction block is movably embedded in the first sliding hole at the inner end of the first limiting groove, and the first limiting slide seat is connected to the inner wall of the first sliding hole through the first suction spring; in the process of inserting the material picking seat downward into the relay bracket, the first suction block is pushed inward by the inner wall of the relay bracket to retract into the first limiting groove. This flexible setting method can effectively avoid the first suction block from scratching the inner wall when it is inserted into the relay bracket, and the first suction spring is in a compressed state during the insertion process. The elastic force of the first suction spring tends to drive the first limit slide and the first suction block to move outward, pushing the outer end wall of the first suction block close to the inner wall of the relay bracket, slightly pressing the inner wall of the relay bracket laterally, and making it easier for the first suction block to better contact with the inner wall surface of the relay bracket, thereby achieving adsorption and fixation of the inner wall of the relay bracket; while ensuring the flexible retraction of the first suction block, the elastic force of the first suction spring can better make the outer end wall of the first suction block closer to the inner wall of the relay bracket, and maintain the outward elastic pressure, thereby achieving stable fixation of the relay bracket.

The present invention is applied to the field of automatic assembly of relay brackets, and belongs to the core mechanism of the automatic feeding machine of relay brackets, and its function is to realize automatic pick-up and placement of relay brackets. Based on the rectangular frame structure of the relay bracket and its material characteristics, the picking and placing method of the present invention is significantly different from the traditional material picking method. The present invention adopts an internal side suction method to fix the relay bracket during material picking, which can effectively reduce the side deformation problem of the relay bracket during material picking and placing. At the same time, the relay bracket is pre-pressed and leveled before picking, which effectively ensures the surface flatness of the relay bracket before picking, avoids the difference in different side angles of the relay bracket due to unevenness when extending into the relay bracket, thereby reducing the problem of abrasion and deformation of the inner wall of the relay bracket when the material is inserted into the relay bracket, and the precise flatness of the material picking helps to improve the accuracy of subsequent relay component assembly. Specifically, the present invention as a whole comprises a connecting support assembly and a material picking assembly. The connecting support assembly is used for bearing support and is connected to the driving mechanism of the material loader. It is driven by the power of the driving mechanism to move in the horizontal plane and in the vertical direction so as to achieve transfer between different workstations of the material loader. A plurality of groups of material picking assemblies are arranged at intervals at the bottom of the support of the connecting support assembly, which are used for automatically picking up and placing a plurality of relay brackets at the same time to improve the efficiency of single picking and placing. The material picking assembly of the present invention uses a bearing frame as a connecting structure. A pressure plate is horizontally arranged at the bottom of the bearing frame, and a through groove is opened on the pressure plate that passes through from top to bottom. A material picking cylinder is vertically arranged on the top plate of the bearing frame, and the output end of the material picking cylinder It is arranged downward and connected with a material picking seat, and the material picking cylinder drives the material picking seat to move up and down through the through slot; in the material picking process, the support drives multiple groups of material picking components to synchronously descend and approach the material station, so that the pressure plate presses the flat relay bracket from above, completes the pre-compression and leveling of the relay bracket, and can effectively ensure the position stability of the relay bracket during the process of the material picking seat extending into the relay bracket; after the pre-compression of the relay bracket is completed, the material picking cylinder drives the material picking seat to pass through the through slot and continue to extend downward into the relay bracket, and after the relay bracket is fixed from the side of the relay bracket through the adsorption piece inserted inside the material picking seat, the support drives multiple groups of material picking components to move upward to realize material movement.The special thing is that the adsorption piece of the present invention is flexibly and movably inserted into the material picking seat body. As an embodiment, the adsorption piece of the present invention is a first suction block of a cylindrical structure, and the first suction block is a magnetic block, which can adsorb and fix a relay bracket made of metal. The material picking seat body of the present invention is horizontally provided with a plurality of first limiting grooves, and the outer end of the first limiting groove extends to the outer side wall of the material picking seat body for slidably inserting the first suction block. The first limiting slide seat connected to the inner end of the first suction block is movably embedded in the first sliding hole at the inner end of the first limiting groove, and the first limiting slide seat is connected to the inner wall of the first sliding hole through the first suction spring; in the process of inserting the material picking seat downward into the relay bracket, the first suction block is pushed inward by the inner wall of the relay bracket to retract into the first limiting groove. This flexible setting method can effectively avoid the first suction block from scratching the inner wall when it is inserted into the relay bracket, and the first suction spring is in a compressed state during the insertion process. The elastic force of the first suction spring tends to drive the first limit slide and the first suction block to move outward, pushing the outer end wall of the first suction block close to the inner wall of the relay bracket, slightly pressing the inner wall of the relay bracket laterally, and making it easier for the first suction block to better contact with the inner wall surface of the relay bracket, thereby achieving adsorption and fixation of the inner wall of the relay bracket; while ensuring the flexible retraction of the first suction block, the elastic force of the first suction spring can better make the outer end wall of the first suction block closer to the inner wall of the relay bracket, and maintain the outward elastic pressure, thereby achieving stable fixation of the relay bracket. Example 2

[0038] like Figure 8 As shown, as an embodiment of the present invention, the adsorption member of the present invention is a second suction block 67, and the second suction block 67 is a cylindrical structure with an inclined extended cross-section, and the second suction block 67 can be slidably inserted in the second limiting groove E opened in the material picking seat body 61; the second limiting groove E is opened in the material picking seat body 61 along the inclined direction, and the outer end extends to the side wall of the material picking seat body 61; the inner end of the second limiting groove E is provided with a second sliding hole F, the second sliding hole F is connected to the second limiting groove E, and the inner diameter is larger than the inner diameter of the second limiting groove E; the inclination direction of the second sliding hole F is the same as the inclination direction of the second limiting groove E.

[0039] A second limiting slide 68 is provided at the inner end of the second suction block 67, and the outer diameter of the second limiting slide 68 is larger than the outer diameter of the second suction block 67 and smaller than the inner diameter of the second slide hole F; the cross section of the second limiting slide 65 extends obliquely, and the inclination direction is the same as the direction of the second slide hole F. The second limiting slide 68 is embedded in the second slide hole F and moves freely in the second slide hole F along the inclination direction, and is blocked and limited by the end wall outside the second slide hole F.

[0040] A second suction spring 69 is provided between the second limiting slide 68 and the second sliding hole F; the second suction spring 69 is inclined along the same direction as the inclination of the second sliding hole F, and its two ends are respectively connected to the second limiting slide 68 and the inner wall of the second sliding hole F, and is used to provide an inclined elastic thrust outward to the second suction block 67, so that the second suction block 67 presses the inner wall of the relay bracket 0.

[0041] As an implementation mode of the present invention, the difference between this embodiment and embodiment 1 is that the cross-section of the second suction block, the second limiting slide seat, and the second slide hole in the vertical direction of this embodiment is inclined, while that of embodiment 1 is horizontal. In actual application, its inclined direction can be gradually extended upward from the middle of the material picking seat to the outside; this kind of inclined extension method can better avoid damage to the inner wall of the relay bracket in the process of the material picking seat extending downward into the interior of the relay bracket, and is more conducive to the second suction block being retracted into the second limiting groove when it is pushed by the inner wall of the relay bracket; at the same time, after the material picking seat is extended, the rebound force of the second material suction spring extends upward from the inside to the outside. According to the principle of force decomposition, the second suction block has the separation of outward pressing and upward pushing on the relay bracket at the same time, so that the relay bracket supports the upper pressure plate to ensure its flatness, and this upward component force is more conducive to removing the relay bracket from the clamping station when picking (equivalent to providing an auxiliary force for upward ejection).
