Double-station tube strip feeding mechanism

Abstract

This utility model provides a dual-station pipe feeding mechanism, including a base, a pipe jacking and branching mechanism, and a conveying mechanism. The pipe jacking and branching mechanism includes a first branching section and a second branching section, which are arranged opposite to each other on the base, two first telescopic mechanisms, and two second telescopic mechanisms. Pipes are stacked sequentially between the first and second branching sections along a first direction perpendicular to the base. The two first telescopic mechanisms and the two second telescopic mechanisms are arranged opposite to each other. Each first and second telescopic mechanism is arranged sequentially in the first direction, with the second telescopic mechanism close to the base. The first and second telescopic mechanisms have extended and retracted states. In the extended state, the first or second telescopic mechanism can support some or all of the pipes. When branching the pipes, the first and second telescopic mechanisms switch between the extended and retracted states accordingly, causing a single pipe to fall from the pipe jacking and branching mechanism to the base. Finally, the conveying mechanism transports the fallen pipe to the feeding position.

Description

Technical Field

[0001] This utility model relates to the field of semiconductor chip sorting, and in particular to a dual-station tube feeding mechanism. Background Technology

[0002] Tube and strip feeding is the most common feeding method in the field of semiconductor sorting machines.

[0003] If the existing single-station tube feeding structure encounters problems such as tube jamming, it is necessary to stop the machine to handle the fault. Production can only continue after the machine is repaired. This will lead to a decrease in output. In addition, the single-station feeding mechanism can feed a small number of tubes at a time, requiring the operator to frequently feed tubes into the mechanism. Utility Model Content

[0004] In view of this, it is necessary to propose a simple-to-operate dual-station tube feeding mechanism.

[0005] In a first aspect, this utility model provides a dual-station pipe feeding mechanism, including a base, a pipe jacking and branching mechanism, and a conveying mechanism. The pipe jacking and branching mechanism includes a first branch section and a second branch section arranged opposite to and spaced apart from each other on the base, two first telescopic mechanisms, and two second telescopic mechanisms. A plurality of pipes are sequentially overlapped between the first branch section and the second branch section along a first direction perpendicular to the base, and both ends of each pipe are slidably disposed between the first branch section and the second branch section, respectively. The two first telescopic mechanisms are arranged opposite to each other; the two second telescopic mechanisms are arranged opposite to each other; each first telescopic mechanism and each second telescopic mechanism are sequentially arranged in the first direction, and the second telescopic mechanism is close to the base; the first telescopic mechanism and the second telescopic mechanism... The structure includes an extended state and a retracted state; in the extended state, the first telescopic mechanism or the second telescopic mechanism can support part or all of several pipe strips; the two first telescopic mechanisms maintain the same state; the two second telescopic mechanisms maintain the same state; when several pipe strips are sequentially divided into sections, the two first telescopic mechanisms and the two second telescopic mechanisms correspondingly switch between the extended state and the retracted state, so that each pipe strip falls from the jacking pipe sectioning mechanism to the base; a conveying mechanism is set relative to the base and located between the first sectioning section and the second sectioning section, for loading the pipe strips falling from the jacking pipe sectioning mechanism and conveying the pipe strips to the loading position.

[0006] Furthermore, in the initial state, the two first telescopic mechanisms are in the extended state, supporting several tubular strips.

[0007] Furthermore, when separating the tubing, after the two second telescopic mechanisms are in the extended state, the two first telescopic mechanisms are in the retracted state, thereby supporting several tubings by the two second telescopic mechanisms. Then, the first telescopic mechanisms are extended to separate the last tubing from the other tubings. Finally, the second telescopic mechanisms are retracted to allow the last tubing to fall.

[0008] Furthermore, each of the first telescopic mechanism and each of the second telescopic mechanisms includes a telescopic arm. When the two first telescopic mechanisms or the two second telescopic mechanisms are in the extended state, the telescopic arm extends relative to each other along a second direction perpendicular to the first direction; when each of the first telescopic mechanism and each of the second telescopic mechanisms is in the retracted state, the telescopic arm retracts.

[0009] Furthermore, each of the first telescopic mechanism and each of the second telescopic mechanisms also includes a cylinder.

[0010] Furthermore, the first branch pipe section and the second branch pipe section are each provided with at least two slots, so that the first branch pipe section and the second branch pipe section are provided with at least two pairs of slots opposite each other; each slot is opened along the first direction, and each pair of slots is respectively placed with a group of several pipe strips.

[0011] Furthermore, the first and second sub-pipe sections are generally rectangular blocks and stand on the base.

[0012] Furthermore, the top of the base is set as a plane, and the first branch pipe, the second branch pipe, and the conveying mechanism are all mounted on the plane.

[0013] Furthermore, limiting plates are provided on both sides of the conveying mechanism, and the limiting plates are installed on the base.

[0014] Furthermore, two first telescopic mechanisms are respectively installed in the first branch pipe section and the second branch pipe section, and two second telescopic mechanisms are respectively installed in the first branch pipe section and the second branch pipe section.

[0015] The aforementioned dual-station pipe feeding mechanism, through the arrangement of the first and second telescopic mechanisms in the jacking and branching mechanism, can stably and efficiently separate individual pipes. Furthermore, the dual-station pipe feeding mechanism, with at least two pairs of slots arranged opposite each other in the first and second branching sections, allows for the initial blocking of the faulty pair of slots and single-station production in the event of a station malfunction. Compared to existing single-station pipe feeding structures, this significantly reduces the output drop caused by malfunctions. Moreover, in the absence of malfunctions, the dual-station pipe feeding structure can feed more pipes at once, with longer intervals between the second feeding, allowing operators to control more equipment, thereby saving labor costs and improving production efficiency.

The accompanying drawings illustrate examples of embodiments of the present invention, wherein the same reference numerals denote the same elements. It is to be understood that the scale shown in the accompanying drawings is not the actual scale of the present invention, and is for illustrative purposes only, and is not a drawing based on the original dimensions.

[0027] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a dual-station pipe feeding mechanism 100 provided in an embodiment of this application. The dual-station pipe feeding mechanism 100 includes a base 1, a pipe jacking and branching mechanism 2, and a conveying mechanism 3. In this embodiment, the top of the base 1 is set as a plane, and the pipe jacking and branching mechanism 2 and the conveying mechanism 3 are both installed on the plane at the top of the base 1.

[0028] Please refer to Figure 2 , Figure 2 This is an exploded perspective view of the dual-station pipe feeding mechanism 100 provided in this embodiment. In this embodiment, the jacking pipe branching mechanism 2 includes a first branch section 21 and a second branch section 22, which are disposed opposite to and spaced apart from each other on the base 1, two first telescopic mechanisms 23, and two second telescopic mechanisms 24. The two first telescopic mechanisms 23 are respectively disposed on the first branch section 21 and the second branch section 22 and are disposed opposite to each other. The two second telescopic mechanisms 24 are respectively disposed on the first branch section 21 and the second branch section 22 and are disposed opposite to each other. In the first branch section 21 or the second branch section 22, the first telescopic mechanism 23 is located above the second telescopic mechanism 24.

[0029] Please refer to Figure 2-3 The first branch pipe section 21 and the second branch pipe section 22 are rectangular blocks, standing upright and mounted on the base 1. The first branch pipe section 21 and the second branch pipe section 22 are each provided with at least two slots 200, such that at least two pairs of slots 200 are arranged opposite each other on the first branch pipe section 21 and the second branch pipe section 22. Each slot 200 is opened along a first direction. In this embodiment, the slot 200 is a slot for placing pipe strips 40. Each pair of slots holds a group of several pipe strips 40.

[0030] In this embodiment, several tubes 40 are stacked sequentially between the first branch section 21 and the second branch section 22 along a first direction Y perpendicular to the base 1, and both ends of each tube 40 are slidably disposed between the first branch section 21 and the second branch section 22.

[0031] In this embodiment, two first telescopic mechanisms 23 are arranged opposite each other on a horizontal plane, and two second telescopic mechanisms 24 are arranged opposite each other on a horizontal plane. The horizontal plane is perpendicular to the first direction Y. Each first telescopic mechanism 23 and each second telescopic mechanism 24 are arranged sequentially in the first direction Y, with the second telescopic mechanism 24 close to the base 1 and located below the first telescopic mechanism 23.

[0032] Please refer to Figure 3 , Figure 3 This is an exploded perspective view of the pipe jacking mechanism provided in this embodiment. Each first telescopic mechanism 23 and each second telescopic mechanism 24 includes a telescopic arm 201. When both first telescopic mechanisms 23 or both second telescopic mechanisms 24 are in the extended state, the telescopic arm 201 extends relative to each other along a second direction X perpendicular to the first direction Y; when each first telescopic mechanism 23 and each second telescopic mechanism 24 are in the retracted state, the telescopic arm 201 retracts. Each first telescopic mechanism 23 and each second telescopic mechanism 24 also includes a cylinder 202. In this embodiment, the telescopic arm 201 is mounted on the cylinder 202. The cylinder 202 provides power for the extension and retraction of the telescopic arm 201 through the supply and delivery of air via an air pipe (not shown), thereby achieving the extended and retracted states of the two first telescopic mechanisms 23 and the two second telescopic mechanisms 24.

[0033] The first telescopic mechanism 23 and the second telescopic mechanism 24 include an extended state and a retracted state. In the extended state, the first telescopic mechanism 23 or the second telescopic mechanism 24 can support some or all of the pipe strips 40. Understandably, the two first telescopic mechanisms 23 maintain the same state, that is, both first telescopic mechanisms 23 are simultaneously in the extended or retracted state. The two second telescopic mechanisms 24 maintain the same state, that is, both second telescopic mechanisms 24 are simultaneously in the extended or retracted state. When the pipe strips 40 are sequentially branched, the two first telescopic mechanisms 23 and the two second telescopic mechanisms 24 correspondingly switch between preset extended and retracted states, thereby causing each pipe strip 40 to fall from the jacking pipe branching mechanism 2 to the base 1.

[0034] Specifically, in the initial state, several tubular sections 40 are loaded between the first branch section 21 and the second branch section 22, and two first telescopic mechanisms 23 are extended, supporting the tubular sections 40. When each tubular section 40 is separated, two second telescopic mechanisms 24 are extended, and two first telescopic mechanisms 23 change from the extended state to the retracted state. Then, the tubular sections 40 fall into the second telescopic mechanisms 24, thus being supported by the two second telescopic mechanisms 24. Next, the first telescopic mechanisms 23 change from the retracted state to the extended state, supporting the tubular sections 40 except for the last tubular section 40, thus separating the last tubular section 40 from the other tubular sections 40. Then, the second telescopic mechanisms 24 change from the extended state to the retracted state, causing the last tubular section 40 to fall.

[0035] Please refer to it again. Figure 1-2 In this embodiment, the conveying mechanism 3 is disposed relative to and mounted on the base 1, and is located between the first branch pipe section 21 and the second branch pipe section 22. The conveying mechanism 3 is a synchronous belt structure for motors, which is used to load the pipe strips 40 falling from the jacking pipe branch pipe mechanism 2 and convey the pipe strips 40 to the loading position. Limiting plates 31 are provided on both sides of the conveying mechanism 3, which are disposed opposite to each other and mounted on the base 1. The limiting plates 31 can restrict the vertical movement of the pipe strips 40.

[0036] In this embodiment, firstly, tubing 40 is placed between the first branch section 21 and the second branch section 22, and supported by two extended first telescopic mechanisms 23. Next, the two first telescopic mechanisms 23 retract from their extended state, causing several tubing 40s to fall into the second telescopic mechanism 24, thus supporting the tubing 40s. Then, the first telescopic mechanisms 23 retract from their retracted state to their extended state, supporting several tubing 40s except for the last tubing 40, thus separating the last tubing 40 from the others. Finally, the second telescopic mechanisms 24 retract from their extended state, causing the last tubing 40 to fall onto the conveying mechanism 3, which then transports the tubing 40 to the loading position.

[0037] The dual-station pipe feeding mechanism in this embodiment, through the arrangement of the first and second telescopic mechanisms in the jacking and branching mechanism, can stably and efficiently separate individual pipes. Furthermore, the dual-station pipe feeding mechanism, with at least two pairs of slots arranged opposite each other in the first and second branching sections, can disable the faulty pair of slots and continue production at a single station in the event of a station failure. Compared to the existing single-station pipe feeding structure, this significantly reduces the output drop caused by failures. Moreover, in the absence of failures, the dual-station pipe feeding structure can feed more pipes at once, with a longer interval between feedings, allowing the operator to control more equipment, thereby saving labor costs and improving production efficiency. Test results show that the production efficiency of the dual-station pipe feeding mechanism in this embodiment is increased by approximately 20% to 30%.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from the spirit and scope of this application. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model is also intended to include these modifications and variations.

[0039] The above-listed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
