[0001] This application relates to the technical field of workpiece processing and transportation, and in particular to a workpiece transfer device and processing production line. Background Technology

[0002] Some workpieces require heating before powder coating during processing. Due to the high temperature of the heating station and the workpiece after heating, it is not suitable for workers to manually operate and transfer the workpiece during processing and transfer to avoid unnecessary burns. To improve the safety and automation of operation and transfer, robotic arms and conveying devices can be used to operate and transfer the workpiece. However, in actual production and processing, the size of different batches of workpieces may vary.

[0003] Therefore, there is a need to provide a workpiece transfer device and processing production line capable of transferring workpieces of various sizes. Summary of the Invention

[0031] The transmission assembly includes a drive sprocket 11, a driven sprocket (not shown), a chain 13, and a drive source 14. The chain 13 is ring-shaped, with one end meshing with the outer circumference of the drive sprocket 11 and the other end meshing with the outer circumference of the driven sprocket. The drive source 14 is used to drive the drive sprocket 11 to rotate around a first direction, which is the axial direction of the drive sprocket 11. The chain 13 includes an inner chain plate and an outer chain plate 131, which are hinged by a chain pin and a sleeve. A first connecting plate 132 is provided on the outer chain plate 131 of the chain 13.

[0032] The support assembly is used to carry the workpiece and achieves linear transmission of the workpiece under the drive of the transmission assembly. The support assembly includes a base plate 21 and a workpiece placement seat 22. The base plate 21 is fixed to the first connecting plate 132. The workpiece placement seat 22 is set on the base plate 21. The base plate 21 is provided with an adjustment groove 211 extending in a first direction. Each base plate 21 is equipped with two workpiece placement seats 22. The workpiece placement seat 22 includes a supporting part 221 and a limiting part 222. The supporting part 221 abuts against the base plate 21 and is used to support the workpiece. The limiting part 222 limits the workpiece in the first direction. The two ends of the workpiece can be placed on one supporting part 221 and limited in the first direction by the two limiting parts 222. The workpiece placement seat 22 can be made of a high-temperature resistant and heat-insulating material. The supporting part 221 supports the workpiece, so that there is a certain height difference between the workpiece and the base plate 21, which can avoid direct contact between the high-temperature workpiece and the base plate 21 and facilitate the robot arm to grasp the workpiece.

[0033] The adjustment assembly is used to adjust the distance between the two workpiece placement seats 22 to accommodate workpieces of different sizes. The adjustment assembly includes a nut 32 and a bolt 31. The bolt 31 passes through the workpiece placement seat 22 and the adjustment groove 211 in sequence and is threadedly connected to the nut 32. The nut 32 is pressed against the base plate 21 to fix the workpiece placement seat 22 to the base plate 21. The nut 32 is loosened and the bolt 31 is slid in the adjustment groove 211 to adjust the distance between the two workpiece placement seats 22. Thus, the size of the placed workpiece is adjusted by changing the distance between the two limiting parts 222.

[0034] In a preferred embodiment, the support portion 221 is provided with a first through hole 223 for the bolt 31 to pass through, and the first through hole 223 is a countersunk hole. In this embodiment, the head of the bolt 31 can be submerged in the first through hole 223, avoiding direct contact between the bolt 31 and the high-temperature workpiece.

[0035] In a preferred embodiment, the limiting part 222 is provided with a second through hole 224 for the bolt 31 to pass through, and the second through hole 224 is a countersunk hole. In this embodiment, the head of the bolt 31 can be submerged in the second through hole 224. Preferably, a workpiece placement seat 22 can be provided with two adjustment components, that is, a bolt 31 can be inserted into the first through hole 223 and the second through hole 224 respectively, so as to achieve a better fixing effect. Preferably, the adjustment component also includes a washer, the bolt 31 passes through the washer, and the washer is located between the nut 32 and the base plate 21.

[0036] In a preferred embodiment, the base plate 21 has an elongated plate-shaped structure extending along a first direction. To make the base plate 21 more stable, the driving sprocket 11, driven sprocket, and chain 13 each include two sets. Both driving sprockets 11 are mounted on the drive shaft 15 and are spaced apart. The first connecting plate 132 on each chain 13 extends in a direction away from the other chain 13. Referring to Figures 2 and 4, the first connecting plate 132 on the left chain 13 extends to the left, and the first connecting plate 132 on the right chain 13 extends to the right. Correspondingly, the two chains 13 are also spaced apart from each other, and the two driven sprockets are also spaced apart from each other.

[0037] Furthermore, the workpiece transfer device also includes a second connecting plate 23, one side of which is fixed to the base plate 21, and the other side of which is fixed to the first connecting plate 132 on the two chains 13.

[0038] Furthermore, a first transmission wheel 16 is provided at one axial end of the drive shaft 15, and a second transmission wheel 17 is provided on the output shaft of the drive source 14, which is connected to the first transmission wheel 16. The first transmission wheel 16 and the second transmission wheel 17 can be directly meshed together, or indirectly connected through a rack and pinion or other intermediate gears.

[0039] In a preferred embodiment, the workpiece conveying device further includes a support assembly supporting the transmission assembly and the load-bearing assembly. The support assembly includes a bracket 41 and a crossbeam 42. The crossbeam 42 is fixed to the top of the bracket 41. Viewed along a first direction, the crossbeam 42 is located on the inner circumference of the chain 13, and the drive shaft 15 is mounted on the crossbeam 42. Preferably, the driven shaft on which the driven sprocket is mounted is also mounted on the crossbeam 42.

[0040] In a preferred embodiment, each base plate 21 is provided with two adjustment grooves 211, which are arranged along a first direction and spaced apart from each other. In this embodiment, the spaced adjustment grooves 211 on the base plate 21 can limit the minimum size of the workpiece, and the area between the two adjustment grooves 211 can facilitate the fixing of the base plate 21 and the second connecting plate 23 by fasteners.

[0041] Of course, in other embodiments, only one adjustment groove 211 may be provided on each base plate 21.

[0042] This utility model also provides a processing production line, which includes the workpiece conveying device in any of the above embodiments. The processing production line also includes a high-frequency coil and a coating tank, with the coating tank located between the workpiece conveying device and the high-frequency coil. In this embodiment, the workpiece can be gripped by a robotic arm, which grips the workpiece and inserts it into the high-frequency coil to rapidly heat the metal workpiece. The heated workpiece is then gripped by the robotic arm and placed into the coating tank for powder coating. After coating, the workpiece can be gripped by the robotic arm again and placed onto the workpiece placement seat 22 of the workpiece conveying device for transport to the subsequent workstation.
