Technical Field

[0001] The invention relates to the field of paint stripping machines, in particular to a spiral loading paint stripping device. Background Art

[0002] In the electronic and electrical manufacturing industry, stripping the paint layer on the surface of electronic components is a crucial process step. This step has a decisive influence on the subsequent wire welding, circuit connection, etc. With the continuous development of laser technology, laser paint stripping machines came into being and gradually became the mainstream choice for paint stripping processes. Laser paint stripping machines use laser irradiation to cause the paint layer on the surface of the wire to produce thermal expansion and contraction effects, thereby achieving paint stripping. At the same time, high-intensity vibrations can directly shatter the stripped paint layer to ensure thorough paint stripping.

[0003] However, the carrier used to carry materials in the laser paint stripping machine in the prior art is often set as a long strip structure. In order to carry more materials, the size needs to be increased along the length direction, which easily makes the carrier larger in volume, causing difficulties in transplanting or increasing the floor space of the equipment. Summary of the invention

[0004] The purpose of the present invention is to provide a spiral loading paint stripping device to solve the problem in the prior art that the material-carrying carrier has a small amount of material to carry at a time and is limited by the difficulty of structural expansion.

DETAILED DESCRIPTION

[0029] The present invention is further described in detail below in conjunction with specific embodiments:

[0030] like Figure 1 As shown, a spiral loading paint stripping device comprises a base 1, a transfer assembly 2 on the base 1, and a loading assembly 3, a paint stripping device 4 and a unloading assembly 5 arranged around the transfer assembly 2. The loading assembly 3 arranged at the loading station supplies the material to be stripped to the transfer assembly 2, and the transfer assembly 2 transfers the material to be stripped to the paint stripping station. After the paint stripping device 4 strips the material, the transfer assembly 2 continues to carry the material into the unloading station to unload the material.

[0031] Combination Figure 2 and Figure 3As shown, the transplanting assembly 2 includes a transplanting drive device disposed on the base 1. In this embodiment, the transplanting drive device is configured as a turret 21, which has a vertical axis and is rotatably connected to the base 1 around the axis. A disc 22 is installed at the end of the turret 21 away from the axis, and the upper end surface of the disc 22 is horizontally arranged as a carrying surface 221 for carrying materials.

[0032] The carrying surface 221 is much larger than the material, that is, the carrying surface 221 of a disk 22 can carry a lot of materials. In order to reasonably utilize the large size of the carrying surface 221, the materials of the present application are stacked one by one along a spiral line on the carrying surface 221, and the materials fill the entire carrying surface 221.

[0033] This spiral stacking method is achieved through two actions: one is that the disc 22 rotates around its own axis, and the other is that the discharge end of the loading component 3 moves synchronously along the radial direction of the disc 22.

[0034] About the rotation of disk 22: Combination Figure 3 and Figure 4 As shown, the disc 22 has a rotating shaft 222 arranged along its own axis, the rotating shaft 222 penetrates the turret 21 and is rotatably connected to the turret 21, and a self-rotation driving device 23 is arranged at the loading station, and the self-rotation driving device 23 can drive the disc 22 located at the loading station to rotate around its own axis. Specifically, the self-rotation driving device 23 is composed of a cylinder 231 vertically fixed on the base 1, a motor 232 connected to the execution end of the cylinder 231, and a friction joint 233 coaxially installed at the driving end of the motor 232. When a disc 22 enters the loading station with the turret 21, the cylinder 231 drives the motor 232 to lift, and the motor 232 drives the friction joint 233 to rotate at the same time. The end of the rotating shaft 222 located below the turret 21 is constructed as a driving end, and the friction joint 233 abuts against the driving end under the lifting of the cylinder 231, and transmits its rotational motion to the disc 22, so that the disc 22 rotates around its own axis.

[0035] Regarding the radial feeding action of the feeding assembly 3: Figure 5 As shown, the loading assembly 3 includes a feeding device 31 for loading materials. In this embodiment, the feeding device 31 adopts a vibrating disk. The feeding device 31 is connected to a feeding plate 32. The end of the feeding plate 32 away from the feeding device 31 corresponds to the carrying surface 221 at the loading station, so that the material can fall onto the carrying surface 221 after being vibrated and output by the feeding device 31. In addition, a loading drive device 33 is arranged below the feeding device 31. The loading drive device 33 is composed of an electric cylinder 331 and a guide rail 332. Among them, the guide rail 332 is arranged along the radial direction of the disc 22 located at the loading station. The execution end of the electric cylinder 331 is connected to the feeding device 31, and can drive the feeding device 31 and the feeding plate 32 to run along the guide rail 332.

[0036] The superposition of the rotation of the disk 22 and the radial movement of the feeding device 31 can realize the spiral stacking of the materials on the disk 22 .

[0037] Furthermore, in order to improve the processing efficiency of the present application, a disc 22 is arranged at each work station around the axis of the turret 21, so that when any disc 22 is at any work station, the other discs 22 are also at the corresponding work station, thereby allowing the loading, paint stripping and unloading actions to be carried out synchronously.

[0038] In addition, in order to further improve the processing efficiency of the present application, the emission end of the paint stripping device 4 is arranged in two groups at an angle of 90° on the base 1, so that in each 90° rotation of the turret 21, the paint stripping operation can be performed on the materials on the two discs 22 at the same time. To this end, the discs 22 are arranged in two groups on the turret 21, a total of eight, and each group of discs 22 is stripped by the same paint stripping device 4.

[0039] like Figure 5 As shown, in the feeding link for two groups of discs 22, the feeding assembly 3 is provided with a parallel feeding mechanism 34. The parallel feeding mechanism 34 is provided with a parallel driver 341 and a parallel guide rail 342, the parallel guide rail 342 is arranged parallel to the adjacent group of discs 22 at the feeding station, and the feeding device 31 and the feeding driving device 33 are slidably arranged on the parallel guide rail 342, so that after completing the spiral feeding of one disc 22, the parallel driver 341 can drive the feeding driving device 33 and the feeding device 31 to move along the parallel guide rail 342, so as to feed the discs 22 of another adjacent group.

[0040] Except for the loading action, the disc 22 does not need to rotate around its own axis, but needs to remain relatively fixed to facilitate the subsequent laser paint stripping and unloading. Figure 6 As shown, a brake device 6 is provided corresponding to the disc 22, and because the two groups of discs 22 are close to each other, a single brake device 6 can control two discs 22. Specifically, the brake device 6 includes a brake pad 61, which abuts against the outer edge surface of the disc 22 under the drive of the brake driver, and can stop the self-rotation of the disc 22 caused by inertia. The brake driver can adopt elastic parts or cylinders 231, motors 232 and other equipment. In this embodiment, the brake driver adopts a spring. A brake releaser 62 is fixed on the base 1 corresponding to the loading station. The brake releaser 62 pulls the brake pad 61 entering the loading station in a direction away from the disc 22, so that the brake pad 61 is separated from the abutment with the disc 22, so that the self-rotation drive device 23 can drive the disc 22 to rotate.

[0041] like Figure 7As shown, the material unloading assembly 5 includes a material unloading push rod 51 and a material receiving box 52 . The material unloading push rod 51 moves in contact with the carrying surface 221 under the drive of the material unloading driver 53 , and pushes the material on the carrying surface 221 into the material receiving box 52 .

[0042] When working:

[0043] Step 1: The disc 22 at the loading station rotates driven by the rotation drive device 23, and the synchronous feeding device 31 moves along the radial direction of the disc 22 with the loading drive device 33, and puts the materials into the disc 22 one by one, forming a spiral discharge.

[0044] Step 2: When one disk 22 is full, the parallel loading mechanism 34 drives the feeding device 31 to move, so that the feeding device 31 continues to feed the adjacent disk 22 .

[0045] Step 3: When the turret 21 drives the disc 22 to leave the loading station, the brake device 6 stops the rotation of the disc 22. After entering the paint stripping station, the two sets of paint stripping devices 4 simultaneously strip the materials on the two discs 22.

[0046] Step 4: After the paint stripping operation is completed, the turret 21 continues to drive the disc 22 into the unloading assembly 5 for unloading.

[0047] Step 5: The empty disc 22 after unloading is brought into the loading station by the turret 21, and the operation in step 1 is repeated.
