Description

Technical Field

[0001] The utility model belongs to the technical field of PCB drill bit production, and relates to a welding positioning device for PCB drill bit production. Background Art

[0002] PCB, the Chinese name for printed circuit board, is also called printed circuit board. It is an important electronic component, a support for electronic components, and also a carrier for electrical connections of electronic components. Because it is made using electronic printing technology, it is called a printed circuit board. In the process of PCB processing, PCB drills are needed to make holes in the board to facilitate circuit design, so PCB drills have been widely used.

[0003] After searching, it is found that a Chinese patent document discloses a welding device for PCB drill bit regeneration production [application number: CN201721183457.6; publication number: CN207326223U]. This welding device includes a welding seat, a clamping mechanism, a heating mechanism and two sets of feeding clamping mechanisms. The top of the welding seat is provided with a positioning groove that runs through the left and right ends thereof; the bar to be welded can be clamped on the welding seat well, effectively ensuring the welding quality, thereby ensuring the welding quality of the PCB drill bit bar. However, after welding is completed, the operator needs to manually remove the finished bar after welding, which has a low degree of automation and reduces the welding efficiency.

[0004] Based on this, we designed a welding positioning device for PCB drill bit production. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the existing technology and propose a welding positioning device for PCB drill bit production. The technical problem to be solved by the device is: how to realize automatic loading and unloading of the welding device for PCB drill bit production and improve welding efficiency.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A welding positioning device for PCB drill bit production comprises a base plate, a blanking hole is opened in the middle position of the base plate, and an induction heating coil is arranged above the blanking hole, two symmetrically distributed slide rails are fixed on the base plate, and a first slide seat and a second slide seat are slidably arranged on the slide rails, two symmetrically distributed fixed plates are fixed on both sides of the base plate, and a first electric push rod for pushing the first slide seat to move and a second electric push rod for pushing the second slide seat to move are fixed on the fixed plates, a push rod is fixed on the first slide seat, a roll plate is fixed on the second slide seat, a sleeve is fixed above the roll plate, and the end of the push rod is slidably inserted in the sleeve, and the upper end of the sleeve is connected to a material box for storing handle or blade bar material.

[0008] The material box is connected with a feeding pipe for connecting to a vibrating feeding tray, and the inner edge of the feeding pipe is provided with a chamfer.

[0009] With the above structure, when in use, the blade and shank bars of the PCB drill bit can be placed on two vibrating loading trays respectively, and then the vibrating loading trays are connected to the feed pipe through a hose. The blade and shank bars can be transported to the two material boxes respectively through the vibrating loading trays, and the chamfers can play a guiding role when the bars pass through the feed pipe to prevent jamming, thereby achieving the effect of long-term automatic loading.

[0010] A thin tube is fixed on the inner side of one end of the sleeve away from the first sliding seat, and a transition slope is arranged at the inner end of the thin tube.

[0011] With the above structure, when in use, the rod falls from the material box into the sleeve, and then the push rod pushes it forward. At this time, the rod moves into the capillary through the transition slope, and its end is exposed, abutting against the rod in another capillary tube. The inner diameter of the capillary tube is consistent with the diameter of the rod. At this time, the capillary tube can better fix the rod and prevent it from shaking. Moreover, the inner diameter of the sleeve is larger than the diameter of the rod, which can reduce the possibility of the rod getting stuck and improve the smoothness of the device operation.

[0012] The diameter of the push rod is consistent with the inner diameter of the sleeve, and one of the push rods is composed of a first short rod and a second short rod, a round tube is fixed on the first short rod, a sliding rod is slidably arranged inside the round tube, and the second short rod is fixed on the sliding rod, an extrusion spring is arranged inside the round tube, and the two ends of the extrusion spring are respectively against the first short rod and the sliding rod.

[0013] With the above structure, when in use, when the ends of the two bars (the blade bar and the handle bar) of the two sleeves are against each other, the spring will be squeezed. When welding, the connecting ends of the two bars will melt. At this time, the squeezing spring will stretch, so that the two bars are fully pressed against each other, preventing the occurrence of cold welding between the two bars and improving the welding effect.

[0014] A baffle plate is arranged on one side of the blanking hole, and a support plate is fixed on the other side of the blanking hole. An inclined plate is arranged on the upper end of the support plate, and the inclined plate is located inside the induction heating coil, and the inclined plate is made of non-metallic material.

[0015] With the above structure, the inclined plate is made of non-metallic material, which can prevent it from heating and melting in the induction heating coil. When welding is completed, the two second slides move away from each other, and the welded finished bar material is separated from the two sleeves, and then the two first slides move away from each other. At this time, the two ends of the welded finished bar material lose the extrusion force and will fall down to the inclined plate, slide down along the inclined plate, and then fall from the drop hole, which is convenient for collection. In addition, the baffle plate can prevent the finished bar material from sliding from the inclined plate to the bottom plate, thereby improving the aggregation effect.

[0016] Compared with the prior art, the welding positioning device for PCB drill production has the following advantages:

[0017] 1. Through the bottom plate, the first slide, the second slide, the ejector rod and the material box, the blade bar and the handle bar of the PCB drill bit can be automatically moved to the welding position and fixed. After the welding is completed, the finished bar falls through the drop hole, which is convenient for collection, thereby improving the automation degree of the welding process and improving the welding efficiency.

[0018] 2. By squeezing the spring and the round tube, during the welding process, when the connecting ends of the two bars melt, the two bars can be driven to be further pressed together to prevent the occurrence of cold welding between the two and improve the welding effect.

[0019] 3. The baffle plate and the tilting plate can guide the finished bar materials during their falling process, making collection more convenient and preventing the finished bar materials from contacting the induction heating coil and damaging the induction heating coil.
