An automated installation device for selectors

Abstract

This invention relates to the field of switch assembly technology, specifically to an automated installation device for selectors. It includes an assembly box, a support base, a pressing component, and ejection devices disposed on both sides of the support base. The support base supports the selector, and symmetrically arranged bearing mechanisms are mounted on the support base. When the selector ring is fitted onto the selector, the bearing mechanisms support the protrusion, ensuring the selector ring is horizontal before assembly. A positioning mechanism is located at the top of the bearing mechanism, comprising a trigger part and a positioning rod. The positioning rod is slidably connected to the bearing mechanism, and a first iron plate is fixedly connected to its end. Positioning is achieved using the tip of the positioning rod, limiting the selector ring's offset. When the selector ring rotates to a preset assembly angle, the positioning rod drives the first iron plate to release the trigger plate, causing the trigger plate to move upward and impact the horizontal end of the first iron plate, thus completing the rotation into position signal and preventing misalignment of the protrusion and slot, which would affect the assembly progress.

Description

Technical Field

[0001] This invention relates to the field of switch assembly technology, and more specifically, to an automated installation device for selectors. Background Technology

[0002] An assembly machine is a mechanical device that combines several parts of a product together through methods such as tight fitting, snap-fitting, threaded connection, bonding, riveting, and welding to obtain a finished product (semi-finished product) that meets the predetermined dimensional accuracy and function.

[0003] In the prior art, when assembling the selector switch, the selector needs to be placed on the support first. Then, the ball bearings are pushed into the slots on both sides of the selector by the horizontal cylinders on both sides. The cylinders hold the ball bearings in place. Then, the selector ring is manually put on the selector. The vertical cylinder pushes the selector ring downward so that the inner walls on both sides of the selector ring cover the ball bearings. The ball bearings abut against the inner walls of the selector ring, thereby assembling the selector and the selector ring.

[0004] However, when the selector ring is manually placed on the selector, the lower edge of the selector ring will first rest on the outer surface of the ball bearing, leaving the unsupported parts of the selector ring suspended in the air. This makes it easy for the ring to tilt, and the protrusions are far from the slot. It is difficult for the protrusions on both sides of the selector ring to be aligned with the slot on the selector. In other words, the protrusions and the slot are misaligned. As a result, when the longitudinal cylinder pushes the selector ring downwards, the misalignment of the protrusions and the slot can easily damage the selector ring or the selector structure during the pushing process, affecting the assembly of the two. Summary of the Invention

[0005] This invention provides an automated installation device for selectors. By rotating the selector ring and positioning it with the tip of the positioning rod, the selector ring offset is limited and the selector ring is rotated to a preset assembly angle, thereby solving the problem mentioned in the background art, namely: the protrusion and the slot are misaligned, affecting the assembly.

[0006] To achieve the above objectives, an automated installation device for a selector includes an assembly box, a support base, a pressing component, and ejection devices disposed on both sides of the support base. The support base supports the selector, and symmetrically arranged bearing mechanisms are provided on the support base. When the selector ring is fitted onto the selector, the bearing mechanisms are responsible for bearing the protrusion, ensuring that the selector ring is in a horizontal state before assembly. A positioning mechanism is provided at the top of the bearing mechanism, which includes a trigger part and a positioning rod. The positioning rod is slidably connected to the bearing mechanism, and a first iron plate is fixedly connected to the end of the positioning rod. The trigger part is elastically connected to the bearing part and is located below the first iron plate. During the rotation of the selector ring, the positioning rods on both sides constrain the inner wall of the protrusion. When the selector ring rotates to the assembly angle, the positioning rod releases the trigger part, and the rotation into position signal is achieved by the impact between the trigger part and the first iron plate.

[0007] Specifically, the triggering part includes a trigger block and a trigger plate fixed to the bottom of the trigger block. The outer contour of the trigger block is arc-shaped, and the arc from the top to the bottom gradually increases. A vertical rod is fixedly connected to the bottom of the trigger plate. An extension plate sleeved on the outside of the vertical rod is fixed to the support plate, and the extension plate is slidably connected to the vertical rod.

[0008] In the above technical solution, the adjustment is made by rotating the selection ring, and the tip of the positioning rod points to the thin end of the protrusion, so that the protrusion corresponds to the groove.

[0009] Based on the above, and in conjunction with the following description, the first iron plate is L-shaped, having a vertical end and a horizontal end. The vertical end is fixed to the positioning rod, and the horizontal end abuts against the arc surface of the trigger block. Under normal conditions, the horizontal end of the first iron plate is in contact with the trigger plate.

[0010] That is, when the trigger plate strikes the horizontal end of the first iron plate, the impact sound is transmitted through the through hole to the loudspeaker, and the sound is amplified by the loudspeaker to remind the worker that the selection ring has been rotated to the assembly position, and then the following assembly process can be carried out.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] In the automated installation equipment of this selector, the positioning rod tip is used for positioning to limit the offset of the selection ring. When the selection ring rotates to the preset assembly angle, the positioning rod drives the first iron plate to release the trigger plate, so that the trigger plate moves up and impacts the horizontal end of the first iron plate, thereby completing the rotation into position signal and preventing the protrusion from misaligning with the slot, which would affect the assembly progress.

[0027] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0028] Therefore, the present invention discloses an automated installation device for a selector, with reference to Figure 1 , Figure 2 As shown, the assembly includes an assembly box 100, a support base 101, a pressing component 102, and ejection devices disposed on both sides of the support base 101. During assembly, the selector 103 is first placed on the support base 101, which supports the selector 103. Then, the ejection devices push the balls into the selector 103. The ejection device includes a transverse cylinder 110 disposed on the assembly box 100. A base 111 is disposed between the transverse cylinder 110 and the support base 101. The base 111 has a ball channel inside, and a ball funnel 112 connected to the ball channel is disposed on the transverse cylinder 110. (Refer to...) Figure 3As shown, the selector 103 corresponding to the ball channel has a notch that matches the ball. When the selector 103 is placed on the support 101, the ball in the ball channel is pushed into the notch by the transverse cylinder 110. The transverse cylinder 110 pushes the ball out. Then, the selector ring 104 is manually put on the selector 103, and the pressing part 102 is used to press the selector ring 104 and the selector 103 together. That is, the ball holds the selector 103 and the selector ring 104 together.

[0029] It should be noted that: Reference Figure 3 As shown, the selector 103 has symmetrically arranged slots 105, and the selector ring 104 corresponding to the slots 105 has protrusions 106.

[0030] When the selector ring 104 is manually placed on the selector 103, the lower edge of the selector ring 104 will first rest on the outer surface of the ball, causing the unsupported parts at both ends of the selector ring 104 to be suspended in the air, making it easy to tilt. Also, the protrusions 106 are far away from the slots 105, and the protrusions 106 on both sides of the selector ring 104 are difficult to keep in the same vertical line as the slots 105 on the selector 103. That is, the protrusions 106 and the slots 105 are misaligned. As a result, when the pressing part 102 pushes the selector ring 104 downward, the protrusions 106 and the slots 105 are not aligned, and the selector ring 104 or the selector 103 structure is easily damaged during the pushing process, affecting the assembly of the two.

[0031] To address the aforementioned problems, the following is based on... Figure 3 Based on and combined Figure 4 As shown, a bearing mechanism 120 is symmetrically arranged on the support base 101. When the selection ring 104 is fitted onto the selector 103, the bearing mechanism 120 is responsible for bearing the protrusion 106, so that the selection ring 104 is in a horizontal state before assembly. A positioning mechanism 130 is provided on the top of the bearing mechanism 120. The positioning mechanism 130 includes a trigger part and a positioning rod 131. The positioning rod 131 is slidably connected to the bearing mechanism 120. The end of the positioning rod 131 is fixedly connected to a first iron plate 132. The trigger part is elastically connected to the bearing part. The trigger part is located below the first iron plate 132. During the rotation of the selection ring 104 (the purpose of which is to make the protrusion 106 correspond to the slot 105 and prevent misalignment), the positioning rods 131 on both sides are used to constrain the inner wall of the protrusion 106. When the selection ring 104 rotates to the assembly angle, the positioning rod 131 releases the trigger part. The trigger part impacts the first iron plate 132 to realize the rotation into position signal.

[0032] First, it should be understood that when the selector ring 104 is fitted onto the selector 103, the lower edge of the selector ring 104 is away from the ball bearing. To keep the selector ring 104 horizontal before pressing, the structure of the bearing mechanism 120 is disclosed below. The bearing mechanism 120 includes a support plate 121 that receives the lower edge of the protrusion 106. A support rod 122 is fixedly connected to the bottom of the support plate 121. A horizontal plate 124 is slidably connected to the bottom of the support rod 122. A collar 123 fitted onto the support base 101 is fixedly connected to the horizontal plate 124. The collar 123 is connected to the support base 101. The support 101 is fixed; on the other hand, a tension spring 125 is elastically fixed between the bottom of the support plate 121 and the horizontal plate 124. Under normal conditions, the tension spring 125 is in a compressed state, that is, when the protrusion 106 contacts the support plate 121, the lower edge of the selector ring 104 does not contact the ball. Under the elastic action of the tension spring 125, the support plate 121 supports the protrusion 106. In this state, the selector ring 104 remains horizontal to prevent the selector ring 104 from being tilted before assembly, which would affect the assembly.

[0033] Conversely, when the selector ring 104 is pressed into the selector 103, the support plate 121 transmits the thrust to the support rod 122 through the support rod 122. The support rod 122 slides between itself and the cross plate 124, and the tension spring 125 is stretched, increasing the elastic potential energy. The premise for achieving the above stable assembly is that the protrusion 106 needs to correspond to the slot 105, and there is no misalignment between the two.

[0034] Specifically, since the placement of the selection ring 104 is done manually, and the state of the protrusion 106 cannot be accurately determined visually, after the selection ring 104 is placed, the inner wall of the protrusion 106 is first brought into contact with the tip of one of the positioning rods 131. Then, the positioning rod 131 on that side is pressed towards the central axis of the support base 101, so that the protrusion 106 on the opposite side abuts against the positioning rod 131. In this way, the selection ring 104 is placed on the support plate 121. Then, the selection ring 104 is rotated so that the tips of the positioning rods 131 on both sides point to the equidistant points of the protrusion 106 (see reference). Figure 7 As shown in the figure, the positioning work is completed, and the protrusion 106 in this state corresponds to the slot 105.

[0035] Thus, an auxiliary block is fixedly installed in the recessed position in the middle of the support plate 121, and several limiting strips 138 are fixedly installed on the outer wall of the positioning rod 131 to limit the rotation of the positioning rod 131. The auxiliary block is slidably installed with the positioning rod 131 and the limiting strips 138. When the inner wall of one side protrusion 106 applies pressure to the tip of the positioning rod 131, the positioning rod 131 moves inward. When the two sides of the protrusion 106 contact the tips of the corresponding positioning rods 131, the lower edge of the protrusion 106 is in contact with the support plate 121.

[0036] Next, let's combine... Figure 5 , Figure 6 As shown, the triggering part includes a trigger block 133 and a trigger plate 134 fixed to the bottom of the trigger block 133. The outer contour of the trigger block 133 is arc-shaped, and the curvature from its top to its bottom gradually increases. A vertical rod 135 is fixedly connected to the bottom of the trigger plate 134. An extension plate 137 fitted outside the vertical rod 135 is fixed to the support plate 121, and the extension plate 137 is slidably connected to the vertical rod 135. In addition, the first iron plate 132 is L-shaped, with a vertical end and a horizontal end. The vertical end is fixed to the positioning rod 131, and the horizontal end abuts against the arc surface of the trigger block 133. Under normal conditions (when... Figure 3 When the protrusion 106 corresponds to the slot 105, the horizontal end of the first iron plate 132 contacts the trigger plate 134; Working principle:

[0037] based on Figure 5 , Figure 6 Based on this, and then combined Figure 7 As shown, after the selection ring 104 is in place, because the inner wall of the protrusion 106 is V-shaped and has the characteristics of being thin in the middle and thick at both ends, when the protrusion 106 and the slot 105 are misaligned, that is, the tip of the positioning rod 131 is located at the thick end of the protrusion 106, Figure 6 The image shows the state of the first iron plate 132 and the trigger block 133 in this state. The horizontal end of the first iron plate 132 abuts against the arc surface of the trigger block 133, and the trigger plate 134 impacts the horizontal end of the first iron plate 132.

[0038] Secondly, a compression spring 136 is elastically connected between the trigger plate 134 and the extension plate 137. The compression spring 136 is sleeved on the outside of the upright 135, and the elastic potential energy of the compression spring 136 is less than that of the tension spring 125. In this way, the extension plate 137 supports the compression spring 136. Then, the selection ring 104 is rotated to adjust the position so that the tip of the positioning rod 131 points to the thin end of the protrusion 106, and the protrusion 106 corresponds to the slot 105.

[0039] Furthermore, the assembly point is found by manually rotating the selection ring 104 back and forth. During the rotation, the thin end of the protrusion 106 gradually approaches the tip of the positioning rod 131 until the tip points to the thin end of the protrusion 106. Under the elastic action of the compression spring 136, the compression spring 136 applies pressure to the trigger plate 134 upward. The trigger block 133 pushes out the horizontal end of the first iron plate 132. The horizontal end of the first iron plate 132 slides along the arc surface of the trigger block 133, and the arc of the top to the bottom of the trigger block 133 gradually increases. When the positioning rod 131 points to the thin end of the protrusion 106 (that is, when the preset assembly angle is reached), the trigger plate 134 and the horizontal end of the first iron plate 132 collide.

[0040] Specifically, when the trigger plate 134 contacts the horizontal end of the first iron plate 132, it indicates that the selection ring 104 has been rotated to the assembly angle. To serve as a reminder and prevent the worker from continuing to rotate the selection ring 104, the horizontal end of the first iron plate 132 corresponding to the trigger plate 134 has a through hole, and a loudspeaker 139 is installed in the through hole; thus, when the trigger plate 134 impacts the horizontal end of the first iron plate 132 ( Figure 6 The dotted line shows the impact between the trigger plate 134 and the horizontal end of the first iron plate 132. The impact sound is transmitted through the through hole to the loudspeaker 139 and amplified by the loudspeaker 139 to remind the worker that the selection ring 104 has been rotated to the assembly position, and then the following assembly process is carried out. Since the trigger block 133 holds the horizontal end of the first iron plate 132 against the ground, the tips of the positioning rods 131 on both sides limit the displacement of the protrusion 106, so that the selection ring 104 can be stably assembled with the selector 103.

[0041] In other words, the positioning rod 131 is used for positioning to limit the offset of the selection ring 104. When the selection ring 104 is rotated to the preset assembly angle, the positioning rod 131 drives the first iron plate 132 to release the trigger plate 134, so that the trigger plate 134 moves upward and impacts the horizontal end of the first iron plate 132, thereby completing the rotation into position signal and preventing the protrusion 106 from being misaligned with the slot 105, which would affect the assembly progress.

[0042] Then, combine Figure 7 , Figure 8 As shown, a filling block 107 is fixedly disposed above the inner wall of each protrusion 106. The size of the filling block 107 is smaller than that of the slot 105. Figure 7 d1 shows the cross-section of the filling block 107, and d2 shows the cross-section of the slot 105, where d2 is larger than d1; when the ball is pushed into the notch, the combination... Figure 9 As shown, the pressing part 102 presses down on the selection ring 104, pressing the selection ring 104 onto the outside of the ball, and the selector 103 is assembled with the selection ring 104 through the ball. During this process, since the selection ring 104 is made of plastic, it has a certain degree of toughness. When the selection ring 104 just contacts the ball, the filling block 107 extends into the groove 105. As the selection ring 104 moves downward, the selection ring 104 wraps around the ball, and the ball pushes the outer wall of the selection ring 104 outward. The filling block 107 then moves inward and presses against the inner wall of the groove 105, improving the tightness of the assembly between the selection ring 104 and the selector 103, thereby realizing the assembly of the selection ring 104 and the selector 103.
