Description

TECHNICAL FIELD

[0001] The present application relates to the field of automatic assembly technology, in particular to an assembly machine with a track displacement feeding mechanism. BACKGROUND

[0002] With the acceleration of industrialization process in China, industrial automation develops rapidly. Industrial automation is very obvious in some automatic equipment, which can liberate labor and improve production efficiency.

[0003] The existing micro switch automatic assembly machine generally comprises a mechanical hand, a first cylinder, a second cylinder and a third cylinder. The first cylinder is used to drive the mechanical hand to clamp the component to be assembled. The second cylinder is used to drive the mechanical hand to move up and down. The third cylinder is used to drive the mechanical hand to move left and right. During assembly, the second cylinder first drives the mechanical hand to move downward. The first cylinder drives the mechanical hand to clamp the component to be assembled. Then the second cylinder first drives the mechanical hand to move upward. Then the third cylinder drives the mechanical hand to move above the clamp. Finally, the second cylinder drives the mechanical hand to move downward to install the component to be assembled in the clamp. In the above assembly process, there are multiple steps of clamping, moving up and down, and moving left and right, and there is a certain time interval between the multiple steps. Therefore, the assembly speed is slow, which greatly reduces the assembly efficiency. In addition, the assembly machine composed of the mechanical hand, the first cylinder, the second cylinder and the third cylinder has a complex structure, which not only increases the production cost, but also occupies a large space.

It has a first position and a second position respectively arranged at both ends of the first straight line direction. The driving mechanism has a first driving member and a second driving member driven by the same power assembly and can move back and forth along a second straight line direction. The second straight line direction intersects the first straight line direction. The track conversion assembly is connected to the first driving member and the part carrier respectively. The track conversion assembly has a first state suitable for converting the movement of the first driving member along the second straight line direction into the movement of the part carrier along the first straight line direction, and a second state in which the first driving member is separated from the part carrier when the second driving member drives the part located at the second position to move and complete the assembly action.

[0007] When the part carrier is at the first position, the linkage assembly is located in the third moving groove; when the part carrier is at the second position, the linkage assembly is located in the first moving groove, and the first moving groove is suitable for moving the linkage assembly therein.

[0008] The first slide rail is provided with a second sliding groove suitable for installing the part and sliding the second driving member.

[0009] The part carrier is provided with an installation groove suitable for placing the part, wherein, at the second position, the installation groove is arranged in correspondence with the second sliding groove.

[0011] The first slide rail is provided with a third slide rail, and the third slide rail is provided with a fourth sliding groove suitable for sliding the first driving member.

[0012] The power assembly comprises a driving cylinder, a push rod and a fixed block, one end of the push rod is connected to the driving cylinder, the other end of the push rod is connected to the fixed block, and the fixed block is assembled to the first driving member and the second driving member through fasteners on the upper side and the lower side of the fixed block.

[0013] The linkage assembly comprises a connecting shaft connected to the part carrier and a rolling member sleeved on the outer wall of the connecting shaft and abutting against the inner wall of the trajectory groove.

[0014] The rack is further provided with a feeding mechanism, and the feeding mechanism comprises a vibrating tray, a feeding track and a straight vibrator, one end of the feeding track is connected to the outlet of the vibrating tray, and the other end of the feeding track is provided with the part carrier.

[0015] The technical scheme of the present application has the following advantages:

[0016] 1. The assembly machine with track displacement feeding mechanism provided by the present application, by setting a track conversion assembly, the track conversion assembly has a first state suitable for converting the movement of the first driving member along the second linear direction into the movement of the part carrier along the first linear direction, and a second state for separating the first driving member from the part carrier when the second driving member drives the part located at the second position to move and complete the assembly action. During assembly, the first driving member first drives the part carrier to move from the first position to the second position through the track conversion assembly, and then the second driving member drives the part located at the second position to move and complete the assembly action. Since the first driving member and the second driving member are both driven by the same power assembly, compared with the prior art which needs multiple cylinder driving modes, the structure is simpler and the production cost is reduced. In addition, since the assembly of the part has only two steps, i.e. the first step of moving the part carrier from the first position to the second position, and the second step of moving along the second linear direction under the driving of the second driving member, the assembly efficiency is greatly improved.

[0017] 2. The assembly machine with track displacement feeding mechanism provided by the present application, the track conversion assembly comprises a track groove, a first sliding rail and a linkage assembly. The track groove has a first moving groove, a second moving groove and a third moving groove which are sequentially communicated. The second moving groove is a diagonal groove or an arc-shaped groove. The first moving groove and the third moving groove are both arranged in parallel with the second linear direction and have opposite extension directions. The first sliding rail has a first sliding groove suitable for the movement of the part carrier along the first linear direction. When the linkage assembly is located in the second moving groove, with the movement of the first driving member along the second linear direction, the inner wall of the diagonal groove or the arc-shaped groove abuts against the linkage assembly, thereby driving the part carrier to move along the first linear direction. The above-mentioned track groove has the advantages of simple structure and low production cost.

[0018] 3. The assembly machine with track displacement feeding mechanism provided by the present application, when the part carrier is at the second position, the linkage assembly is located in the first moving groove, and the first moving groove can move the linkage assembly therein. Thus, when the second driving member drives the part located at the second position to move and complete the assembly action, the linkage assembly moves in the first moving groove, i.e. the part carrier does not link with the first driving member. The above-mentioned structure setting ensures that the first driving member and the second driving member are driven by the same power assembly, and has the advantage of simple structure.

[0019] 4. The assembly machine with track displacement feeding mechanism provided by the present application, the linkage assembly comprises a connecting shaft connected with the part carrier, and a rolling member sleeved on the outer wall of the connecting shaft and abutting against the inner wall of the track groove. The rolling member and the inner wall of the track groove are in rolling friction, so that the wear is small and the service life is prolonged. BRIEF DESCRIPTION OF DRAWINGS

[0036] The present embodiment provides an assembling machine with a track displacement feeding mechanism, as shown in Figure 1 and 2 , which comprises a frame, a part carrier 1, a driving mechanism, a feeding mechanism and a turntable 25.

[0037] The part carrier 1, as shown in Figure 2 and 4 , is shaped with a mounting groove 12 suitable for placing the parts 2, and the part carrier 1 is mounted on the frame and can reciprocate along a first linear direction, and has a first position and a second position separately arranged at both ends of the first linear direction.

[0038] The driving mechanism, as shown in Figure 2 and 3 , is arranged on the frame and is connected with the part carrier 1, and is used to drive the part carrier 1 to reciprocate along the first linear direction.As shown, the first driving member 3 and the second driving member 4 are driven by the same power assembly and can move reciprocally along the second linear direction, and the trajectory conversion assembly is connected with the first driving member 3 and the part carrier 1 respectively.

[0039] The trajectory conversion assembly has a first state suitable for converting the movement of the first driving member 3 along the second linear direction into the movement of the part carrier 1 along the first linear direction, and a second state suitable for separating the first driving member 3 from the part carrier 1 when the second driving member 4 drives the part 2 in the second position to move and complete the assembly action. Figure 3 As shown, the trajectory conversion assembly comprises a trajectory groove 5 provided on the first driving member 3, having a first moving groove 6, a second moving groove 7 and a third moving groove 8 connected in sequence, the second moving groove 7 is a diagonal groove or an arc-shaped groove, the first moving groove 6 and the third moving groove 8 are both arranged in parallel with the second linear direction and have opposite extension directions; a linkage assembly having one end fixed with the part carrier 1 and the other end extending into the trajectory groove 5 and being driven by the first driving member 3, the linkage assembly comprises a connecting shaft 19 connected with the part carrier 1, and a rolling member 20 sleeved on the outer wall of the connecting shaft 19 and abutting against the inner wall of the trajectory groove 5. When the part carrier 1 is in the first position, the linkage assembly is located in the third moving groove 8; when the part carrier 1 is in the second position, the linkage assembly is located in the first moving groove 6, and the first moving groove 6 can allow the linkage assembly to move therein.

[0040] As shown, the first slide rail 9, the second slide rail 13 and the third slide rail 14 are arranged on the frame. Figure 3 As shown, the first slide rail 9 has a first slide groove 10 suitable for allowing the part carrier 1 to move along the first linear direction, and a second slide groove 11 suitable for mounting the part 2 and allowing the second driving member 4 to slide; the second slide rail 13 is arranged above the first slide rail 9 and extends towards the power assembly, and the second slide rail 13 is formed with a third slide groove suitable for allowing the second driving member 4 to slide; the third slide rail 14 is formed with a fourth slide groove 15 suitable for allowing the first driving member 3 to slide. When the part carrier 1 is in the second position, the mounting groove 12 is arranged corresponding to the second slide groove 11.

[0041] The power assembly comprises a driving cylinder 16, a push rod 17 having one end connected with the driving cylinder 16 and the other end connected with a fixed block 18, and the fixed block 18 is assembled with the first driving member 3 and the second driving member 4 through fasteners on the upper and lower sides thereof.

[0042] The feeding mechanism includes a vibrating disc 21, a feeding track 22, and a linear vibrator 23. One end of the feeding track 22 is connected to the outlet of the vibrating disc 21, and the other end is provided with the part carrier 1.

[0043] Turntable 25 has a plurality of clamps 24 spaced apart along its circumference, as in this embodiment, such as Figure 9 As shown, fixture 24 is used to assemble microswitches, and part 2 is the pin.

[0044] The working principle of the assembly machine with trajectory shifting feeding mechanism provided by this invention is as follows:

[0045] Before assembly, such as Figure 5 and 6 As shown, the part carrier 1 is located in the first position, and the linkage assembly is located in the first moving groove 6. When the power assembly drives the first driving member 3 and the second driving member 4 to move to the right, the linkage assembly enters the second moving groove 7 from the first moving groove 6 and moves along the second moving groove 7. Since the second moving groove 7 is an inclined groove or an arc-shaped groove, the linkage assembly, driven by the inner wall of the second moving groove 7, drives the part carrier 1 to move from the first position to the second position. Figure 7 and 8 When the second position is shown, the linkage component enters the third moving slot 8. As the first driving component 3 continues to move to the right (the linkage component slides relative to the third moving slot 8), the positions of the linkage component and the part carrier 1 will remain unchanged, while the second driving component 4 will drive the part 2 to move to the right and complete the assembly.

[0046] The assembly machine with a trajectory shifting and feeding mechanism provided by this invention, by setting a trajectory conversion component, has a first state suitable for converting the movement of the first driving member 3 along a second straight line direction into the movement of the part carrier 1 along a first straight line direction, and a second state in which the first driving member 3 is separated from the part carrier 1 when the second driving member 4 drives the part 2 located at the second position to move and complete the assembly action. During assembly, the first driving member 3 first drives the part carrier 1 from the first position to the second position through the trajectory conversion component, and then the second driving member 4 drives the part 2 located at the second position to move and complete the assembly action. Since the first driving member 3 and the second driving member 4 are both driven by the same power component, compared with the prior art which requires multiple cylinders to drive, this structure is simpler and reduces production costs. In addition, since the assembly of part 2 only has two steps, namely, the first step is to follow the part carrier 1 from the first position to the second position, and the second step is to move along the second straight line direction under the drive of the second driving member 4, this greatly improves the assembly efficiency.

[0047] Obviously, the above embodiments are merely example for clearly illustrating but not limitation to the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments need not and can not be enumerated. The obvious changes or variations derived from the above description are still within the protection scope of the present application.
