Abstract
Description
Technical Field
[0001] The utility model relates to the field of USB inner and outer shell assembly, in particular to an assembly vehicle. Background Art
[0002] The USB structure includes the following: Figure 1 The assembled structure is shown.
[0003] At present, the outer shell and the inner shell are assembled by manual labor and manual equipment. The manual equipment is used to push the inner shell into the outer shell. However, the manual equipment has the problem of poor accuracy, which is mainly reflected in the weak positioning effect of the outer shell. The outer shell will still shake and deviate left and right in the manual equipment. When the outer shell deviates from the preset position in the manual equipment by 1 cm, this mismatched assembly will cause deformation or scratches on the outer shell and the inner shell.
[0004] In other words, there is currently a lack of a vehicle that can accurately assemble the above-mentioned inner shell and outer shell, and designing such a vehicle has become the first purpose of the project.
[0005] During development, it was considered that this carrier can be directly applied to the welding process and can replace the positioning mechanism in the welding process. This positioning mechanism is used to correct the position between the inner shell and the outer shell. Otherwise, the inner shell and the outer shell after welding are relatively tilted, and the produced iron shell is a defective product and cannot be used anymore. However, the structure of the positioning mechanism is not suitable for use on this carrier. Correcting the position of the outer shell can be solved from the design idea of positioning the outer shell for the first purpose. Designing a structure for positioning the inner shell on the carrier has become the second purpose of the project. Utility Model Content
[0006] In order to solve the above problems, the utility model provides an assembly carrier, aiming to solve the problems of product deformation and scratches.
[0007] The utility model provides an assembly carrier, and secondly solves the problem of positioning the inner shell on the carrier.
[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0009] An assembly carrier, characterized in that the carrier body is used to position the outer shell, the outer shell located on the carrier body is constrained by the positioning component on the carrier body, the positioning component is formed with an opening structure for the inner shell to pass into the outer shell, the part of the positioning member opposite to the opening structure is a slider with a tongue, the tongue points to the opening structure, and the inner shell is sleeved on the tongue and positioned by the above-mentioned tongue.
[0010] Furthermore, the two parts opposite to each other in the positioning component are movable clamps, and the carrier body has an area for the movable clamps to rotate. The movable clamps are rotatably connected to the carrier body in the area and are pulled by the tension spring on the carrier body to form a clamping state.
[0011] Furthermore, the area expands to the side of the carrier body with the rotation center point of the movable clamp rotating. The movable clamp has a handle that rotates outward from the area in the clamping state. The movable clamp is switched from the clamping state to the open state by pressing the handle to rotate in the opposite direction.
[0012] Furthermore, a limiting member entering into the opening structure is provided on the carrier body to limit the housing on the carrier body.
[0013] Furthermore, a lifting plate is provided on the end of the limiting member away from the opening structure, and a lifting rod located below the movable clamping claw is provided on the lifting plate.
[0014] Furthermore, the handle has a pressed side surface, and the area of the side surface close to the push rod is an inclined surface.
[0015] Beneficial effects of the utility model:
[0016] 1. The utility model is a carrier suitable for positioning an outer shell. When assembled with an inner shell, the outer shell can be fully positioned, and the positioning components on the carrier body abut against the outer shell, so that the outer shell is in a constrained state, that is, the position of the outer shell is firmly fixed, which solves the problem of deformation and scratches in assembly caused by position deviation.
[0017] 2. The positioning member in the utility model adopts a tongue opposite to the inner shell, which plays a role in positioning the inner shell, so that the position of the inner shell relative to the outer shell is corrected by the tongue, thereby solving the problem of positioning the inner shell on the carrier.

[0028] like Figure 3-10 As shown, it is a structural diagram of the utility model. The utility model is an assembly carrier 1. The outer shell S1 located on the carrier body 100 is constrained by a positioning component on the carrier body 100. The positioning component is formed with an opening structure k for the inner shell S2 to penetrate into the outer shell S1.
[0029] It can be seen that when assembled with the inner shell S2, the constrained outer shell S1 cannot be offset. After the outer shell S1 is effectively positioned, the assembly result will not have deformation and scratches.
[0030] The utility model can be applied to automation equipment, and the specific application is as follows Figure 2 As shown in the figure, it can be known that the utility model is applied on a rotating platform 2, and the outer shell S1 and the inner shell S2 are moved to different workstations through the rotating platform 2.
[0031] The above-mentioned workstations include but are not limited to the loading of the outer shell S1, the assembly of the inner shell S2 with the outer shell S1 after loading, welding, and stripping.
[0032] In the process of the carrier body 100 being rotated to the outer shell S1 for loading via the rotating platform 2, the outer shell S1 is fed onto the carrier body 100 and constrained by the positioning component. Then, the rotating platform 2 is rotated again, and the carrier body 100 is moved to the process of loading the inner shell S2. At this time, the inner shell S2 is directly inserted into the positioned outer shell S1. Then, the rotating platform 2 is rotated once more, and the carrier body 100 is moved to the welding process, and the outer shell S1 and the inner shell S2 are fixed together through welding.
[0033] The two parts opposite to each other in the positioning component are movable clamps 100a, which are for the convenience of assembly of the shell S1 on the carrier body 100 and removal after subsequent welding. The carrier body 100 has an area 100s for the movable clamp 100a to rotate. The movable clamp 100a is rotatably connected to the carrier body 100 in the area 100s, and is pulled by the tension spring (not shown in the figure) on the carrier body 100 to form a clamping state; it should be noted that since the hook of the tension spring is connected to the area 100s on the movable clamp 100a close to the clamping portion L1, the movable clamp 100a is maintained in a clamped state.
[0034] It is not difficult to see that this solution has the advantage of a simple structure and can reduce a large amount of the carrier's volume, making it easier for the carrier to move back and forth between various workstations.
[0035] The above-mentioned area 100s expands to the side of the carrier body 100 with the rotation center point of the movable clamp 100a. This is to allow the handle L2 of the movable clamp 100a to be located outside the carrier body 100 in the clamping state, and to be separated from the area 100s inside the carrier body 100. By pressing the handle L2 to rotate in the opposite direction, the movable clamp 100a can be switched from the clamping state to the open state.
[0036] from Figure 3-4 It can be seen that in the automated equipment, a pushing mechanism is provided to push the movable clamp 100a to open. The pushing mechanism is located below the carrier body 100. The pushing mechanism includes a pushing cylinder 41 and a pushing plate 42 connected to the piston rod of the pushing cylinder 41. The pushing plate 42 pushes the handle L2 away from its original position through the pushing cylinder 41, so that the handle L2 rotates back to the area 100s.
[0037] Furthermore, in order to improve the smoothness of the rotation of the handle L2, the handle L2 is an inverted cone-shaped structure, and the push plate 42 has a positive slope with a slope greater than that of the handle L2. The positive slope and the side surface of the handle L2 are in a relative position relationship with each other. When the push cylinder 41 pushes the push plate 42, the positive slope contacts the handle L2 and guides the handle L2 to achieve rotation. Fig.10 As shown, Fig.10 The lead line shown is where the shank L2 collides with the positive bevel.
[0038] The carrier body 100 is provided with a limiting member 200 that enters into the opening structure k, and is used to limit the outer shell S1 on the carrier body 100. This ensures that the positions of the outer shell S1 and the inner shell S2 are completely constrained and cannot move during the welding process.
[0039] A lifting plate 201 is provided on the end of the limiting member 200 away from the opening structure k, and a lifting rod 202 is provided on the lifting plate 201 and located below the movable clamp 100a. This is a reuse of the push plate 42. The limiting member 200 is lifted up by the push plate 42. In this way, the use of power source can be saved and the structure of the automation equipment can be further optimized.
[0040] During use, when the movable clamping jaw 100a switches from the clamping state to the open state, the rotation amplitude is relatively large. Therefore, in order to prevent the limiting component 200 which uses the same power source as the movable clamping jaw 100a from exceeding the stroke sufficient for normal use, the top surface of the push plate 42 is provided with a slide groove 42' opposite to the push rod 202. The push rod 202 is horizontally placed and enters the slide groove 42' through the circumferential surface. In other words, the movement of the limiting component 200 is delayed. After the push plate 42 moves to a sufficiently high stroke, the push rod 202 is lifted up through the bottom of the slide groove 42'. In this way, the limiting component 200 will not affect the use of other components in the welding process due to its excessive height.
[0041] The part of the positioning member opposite to the opening structure k is a slider 100b with a tongue 100b', and the tongue 100b' points to the opening structure k. The function of the tongue 100b' is to position the inner shell S2. Before the inner shell S2 is placed, the slider 100b is away from the opening structure k. When the inner shell S2 is inserted, the slider 100b will also be driven at the same time, so that the tongue 100b' moves toward the inner shell S2. That is to say, the action of the inner shell S2 penetrating into the outer shell S1 and the action of the tongue 100b' penetrating into the inner shell S2 are carried out simultaneously. The final state remains that the outer shell S1 is sleeved on the inner shell S2, and the inner shell S2 is sleeved on the tongue 100b'. The use of the tongue 100b' is to prevent the inner ring surface of the inner shell S2 from shaking due to lack of sufficient support during the welding process.
[0042] A telescopic cylinder 21 is also provided on the rotating platform 2 , and the movable end of the telescopic cylinder 21 is opposite to the slider 100 b . The telescopic cylinder 21 can push the latch tongue 100 b ′ into the inner shell S2 .
[0043] The above implementation mode is only a description of the preferred implementation mode of the utility model, and does not limit the scope of the utility model. Without departing from the design spirit of the utility model, various modifications and improvements made to the technical solution of the utility model by ordinary engineering and technical personnel in this field should fall within the protection scope determined by the claims of the utility model.
