In this way, the position of the components is subject to certain errors, resulting in a reject of the assembled product.
The present application positions the component in a first direction by positioning assembly 46 and positions and clamps the component in a second direction by clamping assembly 47. Thereby ensuring that the elements are in one position each time the material is fed, and greatly reducing errors. Moreover, after the clamping component 47 positions the clamping component, the jacking component 44 descends to suspend the uppermost component, so that the manipulator 9 can conveniently clamp or the sucker can conveniently adsorb the uppermost component, and the method has good practical significance.
Preferably, the first direction is substantially perpendicular to the second direction. Specifically, the first direction and the second direction are two directions perpendicular to each other on a horizontal plane.
As shown in fig. 10, in an alternative embodiment, the detecting assembly includes a first detecting member 57 disposed on the clamping member 56, and a second detecting member 59 disposed on the first supporting seat 52 and/or the second supporting seat 63. The second sensing member 59 has a height lower than that of the first sensing member 57. Preferably, the second detecting member 59 is disposed on the second support base 63. The first detecting member 57 is provided on the clamping member 56, corresponding to the indirect mounting of the second support base 63, so that the positional relationship between the first detecting member 57 and the second detecting member 59 is ensured. When the jacking mechanism drives the element to ascend, the ascending speed is reduced when the jacking mechanism ascends to the position of the second detection piece 59, and when the jacking mechanism continuously ascends to the position of the first detection piece 57, the jacking mechanism stops, so that the position of the element can be well ensured. The second drive member 60 drives the two clamping members 56 towards each other to clamp the uppermost component, and the jacking assembly 44 is then lowered so that the remaining components are lowered to a level that is not detectable by the second detection member 59, thereby facilitating the clamping or absorption of the uppermost component by the robot 9. Specifically, the first detection piece 57 is provided at a position on the clamping piece 56 at the same height as the third abutment surface.
As shown in fig. 10 and 11, in an alternative embodiment, the first positioning member 54 is provided with a first abutment surface for abutting against the plate-like element. The second positioning member 58 is provided with a second abutting surface for abutting against the plate-shaped element. The clip 56 is provided with a third abutment surface to abut against the plate-like member. The heights of the first abutting surface and the second abutting surface are both larger than that of the third abutting surface. It will be appreciated that the first and second positioning members 54, 58 position the components from a first direction. Two gripping members 56 grip the element from a second direction. The height of the first abutting surface and the height of the second abutting surface which are used for positioning are larger than that of the third abutting surface which is used for clamping, so that the element can be positioned in two directions, the clamped element is ensured to be in a preset position, and the precision is ensured.
Preferably, the height of the first abutment surface is 2 to 4 plate-like elements thick. The height of the second abutting surface is larger than that of the first abutting surface. The height of the third abutting surface is 1 plate-shaped element.
As shown in fig. 10 and 11, in an alternative embodiment, the second detecting member 59 and the second positioning member 58 are disposed on the second driving member 60. The second positioning member 58 is located above the second detecting member 59, and extends from above the second detecting member 59 to a side of the second detecting member 59 facing the storage chute. The second positioning member 58 is provided at a middle portion thereof with a first detecting groove for passing the detecting light of the second detecting member 59 therethrough. The second positioning member 58 has a stepped cross-section. The portion provided with the second abutment surface is lower than the portion disposed on the second driver 60.
Specifically, the second detecting member 59 and the second positioning member 58 are disposed on the side of the finger cylinder, not on the finger, and thus are not driven by the finger cylinder. In the present embodiment, the detection light of the second detecting member 59 and the second abutting surface of the second positioning member 58 are at the same height. That is, the height of the second detecting member 59 and the portion of the second positioning member 58 provided with the second abutment surface are on the same horizontal plane. The second abutment member is closer to the magazine than the second detector 59. In order for the second detecting member 59 to be able to detect the component, a first detecting groove through which the detection light of the second detecting member 59 passes is provided on the second positioning member 58. In order to save space, the second positioning member 58 extends upward from the second detecting member 59 toward one side of the storage tank, and then extends toward the second detecting member 59 to cover the second detecting member 59, so as to be disposed on the second driving member 60, thereby forming a step-shaped second positioning member 58.
In an alternative embodiment, as shown in fig. 10 and 11, the side of the gripper 56 facing the magazine is provided with an abutment projection. The third abutting surface is arranged on the abutting bulge. The abutting projection is provided with a second detection groove through which the detection light of the first detection member 57 passes. The upper surface of the clamping member 56 is provided with a mounting groove for mounting the first detection member 57. The second detection groove is communicated with the mounting groove. The detection light of the first detection member 57 is at least partially within the height range of the third abutment surface. The detection light beam of the second detector 59 is located within the height range of the second contact surface.
Specifically, since the clamping member 56 is used to clamp one element at a time. Thus, the third clamping surface is elongated and has a relatively small thickness. In order to provide a certain strength to the clamping member 56, the main body of the clamping member 56 needs to have a certain cross-sectional area to avoid deformation. To provide the third abutment surface, a projection is provided on the side of the clamp 56 facing the magazine, and the third abutment surface is provided on the projection. In order to ensure that the element stops at the position where it rises to the third abutment surface, the detection light of the first detector 57 and the third abutment surface are set at the same height. That is, a mounting groove for mounting the first detecting member 57 is provided on the clamping member 56, and then a second detecting groove for communicating the abutting projection and the mounting groove is provided, thereby ensuring that the detecting light of the first detecting member 57 and the second abutting surface are located at the same height. The accuracy of positioning is ensured, and the method has good practical significance.
It should be noted that the second detecting member 59 and the second positioning member 58 are disposed on the upper surface of the second driving member 60. Therefore, the height of the detection light of the second detecting member 59 and the second abutting surface of the second driving member 60 is higher than that of the finger of the second driving member 60. To ensure that the third clamping surface of the gripper member 56 is within the height of the second clamping surface, the gripper member 56 extends upwardly from the second drive member 60 and then to the second directional side of the magazine to form a 7-shaped configuration.
In an alternative embodiment, as shown in fig. 11, the clamping assembly 47 further includes a step seat 64 disposed on the second drive member 60. The step seat 64 has a first step surface for mounting the second detecting member 59, and a second step surface for mounting the second positioning member 58. The first step surface is lower than the second step surface. Specifically, the second positioning member 58 at least needs to abut against the uppermost element. The second detecting member 59 is used to detect whether the element is lowered or raised to a certain height. Therefore, the height of the second detection member 59 is at or below the height of the second abutment surface. Based on the stepped second positioning member 58, the second positioning member 58 and the second detecting member 59 can be fixed relatively well by the step seat 64. To ensure the position relationship of the two.
In an alternative embodiment, as shown in fig. 11, the first retainer 54 is provided with an abutment step at its end. The abutment step is located above the plate-like element when the plate-like element is at the normal feeding height. Specifically, the end of the first positioning member 54 is stepped to prevent the clip from being lifted.
In an alternative embodiment, as shown in FIG. 11, the positioning assembly 46 further includes a third positioning member 55. The third positioning member 55 is lower than the first positioning member 54. The end surface of the third positioning member 55 is a flat surface. The first positioning member 54 and the third positioning member 55 are each of a rod-like structure. The second positioning member 58 has a first detection groove formed in the middle thereof, and thus the second contact surfaces are end surfaces on both left and right sides of the first detection groove. In order to be able to balance the components under force, a third positioning element 55 is provided.
In an alternative embodiment, as shown in fig. 8, the material holder 48 is symmetrically provided with two material storage troughs. The number of the jacking assemblies 44, the positioning assemblies 46 and the clamping assemblies 47 is two, and each jacking assembly, the positioning assemblies 46 and the clamping assemblies 47 corresponds to one storage tank. The two positioning assemblies 46 are symmetrically arranged. Two jacking assemblies 44 are symmetrically arranged. The two clamping assemblies 47 are arranged in parallel. Specifically, through two stockchutes, two jacking assemblies 44, two positioning assemblies 46 and two clamping assemblies 47 which are symmetrically arranged, two elements can be provided at the same time, so that the feeding speed is increased, and the method has a good practical significance.
In an alternative embodiment, as shown in fig. 9, the feeder device 10 further comprises a magazine 49, the magazine 49 being used for placing the plate-like elements and being capable of being at least partially inserted into the magazine. The bottom of the element box 49 is provided with a through hole communicated with the material ejecting through hole. The element case 49 is composed of upper and lower portions, and the inner diameter of the lower portion is smaller than that of the upper portion. The element case 49 is C-shaped in cross section. In particular, the component case 49 of the C-shaped configuration enables the number of components inside the component case 49 to be visually observed, and facilitates the placement or removal of the components. Preferably, the material holder 48 is provided with a sight opening communicating with the reservoir, the sight opening facing the C-shaped opening of the cartridge 49.
As shown in fig. 9 to 10, in an alternative embodiment, the magazine assembly 45 further includes a third driving member 51 disposed on the loading base 4, and a material turntable 50 disposed on the third driving member 51.

The material ejecting through holes are formed in the material turntable 50. The second support is disposed on the feeding base 4. The clamping assembly 47 further includes a fourth driving member 62 disposed on the second supporting seat 63. And a third support base 61 disposed on the fourth driving element 62. The second driving member 60 is disposed on the third support seat 61. The fourth driving member 62 is used for driving the third supporting seat 61 to move close to or away from the storage tank.
Specifically, the third driving member 51 drives the material turntable 50 to rotate with the material seat 48 and the component box 49. To prevent the cartridge 49 from colliding with the positioning assembly 46 or the clamping assembly 47 during rotation, the clamping assembly 47 is provided with a structure that is close to or remote from the cartridge 49. Namely, a third support seat 61 slidably disposed on the second support seat 63, and a fourth driving member 62 for driving the third support seat 61 to slide. The fourth driver 62 is a telescopic cylinder. When the material turntable 50 does not rotate, the fourth driving member 62 drives the third supporting seat 61 to approach the material storage tank, so that the second positioning member 58 can be located at a predetermined position, and thus, cooperates with the third positioning member 55 to achieve the positioning in the first direction.
In this embodiment, the feeding device 10 is directly mounted to the loading base 4. In other embodiments, the feeding device 10 further comprises a feeding seat. The first support seat 52, the second support seat 63, the third driving element 51, the jacking assembly 44 and the like are all arranged on the feeding seat, so that the feeding seat and the jacking assembly form a single whole. So as to be convenient for installation and mobile selling.
