Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, specifically to a tooling rotary table for circuit boards. Background Technology

[0002] In the modern electronics manufacturing industry, automated processing of circuit boards has become a mainstream trend. As a key piece of equipment in the circuit board processing flow, the tooling rotary table undertakes the important task of accurately transporting circuit boards to various processing stations. Currently, common circuit board processing production lines are usually equipped with a feeding device that works in conjunction with the tooling rotary table. The feeding device is responsible for transferring the circuit boards from the material storage area to the station of the tooling rotary table, which then transports the circuit boards sequentially to different processing areas such as drilling, soldering, and testing by rotating.

[0003] However, in actual production, traditional tooling rotary tables have obvious defects. When the feeding device moves the circuit board to the station of the tooling rotary table, the circuit board is prone to displacement during the transfer process due to various factors such as mechanical transmission errors, irregular material placement, and vibration during the transfer. Moreover, after the circuit board is moved into place, the traditional tooling rotary table still relies on manual operation to fix it in place. This manual fixing process not only consumes a lot of time and seriously reduces production efficiency, but also fails to meet the demand for efficient operation in modern large-scale production. In addition, in order to correct the processing position deviation, additional manpower and time are required for manual calibration or rework, which undoubtedly further reduces production efficiency and restricts the high-quality development of the electronics manufacturing industry. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: a tooling rotary table for circuit boards, comprising an operating table and a turntable, a conveyor table and a loading / unloading assembly mounted on the operating table, wherein a pre-placement assembly located between the conveyor table and the turntable is also mounted on the operating table, and four sets of bearing stations are mounted on the surface of the turntable.

[0005] The pre-layout assembly includes a pre-layout platform and a side plate. A first plate is slidably connected to the pre-layout platform and a first rake plate that covers the first plate is fixed thereon. A counter-pushing part is installed at the bottom that is opposite to the spacing of the first rake plate. A plurality of first push plates that are respectively opposite to the protruding end of the first rake plate are installed on one side of the first plate and are located at the bottom of the first rake plate for limiting sliding. The side plate and the pre-layout platform are equipped with a pushing part that pushes the first plate to move back and forth.

[0006] The carrying station includes a carrier plate and a support plate. A second plate slides on the carrier plate and a second rake plate is fixed to cover the second plate. A second push plate is fixed to the top of the second plate, which slides at the bottom of the second rake plate and is opposite to the protruding end of the second rake plate. A pusher is installed between the operating table and the carrier plate to push the second plate to move back and forth. A side stop is installed on the support plate.

[0007] Furthermore, the pushing part includes a pushing cylinder fixed on the side plate opposite to the first plate, and a first guide rod passing through the pre-layout stage is fixed at the other end of the first plate. A first spring located in the slide groove of the pre-layout stage is sleeved on the outer side of the first guide rod.

[0008] Furthermore, the pushing part includes a top-pushing cylinder installed at the bottom of the pre-placement platform. The piston rod of the top-pushing cylinder is fixed with a top-pushing plate. The top-pushing plate is rake-shaped, and multiple protruding ends correspond to the protruding ends of the first rake plate and the first push plate, respectively.

[0009] Furthermore, the pushing part includes two sets of pushing cylinders installed on the operating table. The piston rods of the two sets of pushing cylinders are respectively opposite to one end of the second plate on one of the two sets of carrier plates. The other end of the second plate is fixed with a second guide rod that passes through the carrier plate. A second spring located in the slide groove of the carrier plate is sleeved on the outside of the second guide rod.

[0010] Furthermore, the top of the second rake plate is fixed with a first baffle by screws, and a plurality of L-shaped plates are formed on one side of the first baffle. The L-shaped plates are located between the second rake plate and the second baffle. The top of the first baffle is provided with a waist hole.

[0011] Furthermore, the side stop includes a second guide rod that is limited and passes through the support plate. A second baffle that slides with the support plate is fixed to the top of the second guide rod. The top of the second baffle is higher than the top of the carrier plate. A second spring is sleeved on the outside of the second guide rod.

[0012] Furthermore, a protruding plate located inside the support plate is fixed to one side of the second baffle, and an upper-lifting cylinder is fixed to the operating table. A pressure plate located above the protruding plate is fixed to the ejector end of the upper-lifting cylinder.

[0013] Furthermore, a plurality of second guide rods are provided on the back side of the carrier plate, and one end of each second guide rod is fixed with a movable plate that slides with the turntable. The movable plate is L-shaped and one side is in contact with the second baffle.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The tooling rotary table of this circuit board, through the operation of the push cylinder and top-feed cylinder in the pre-placement component and the bearing station, pushes the corresponding first and second plates to move, thereby moving the pick away from the rake plate to facilitate the placement of the circuit board. The cylinder resets, the spring releases its elasticity, and pushes the plate to drive the pick to bring the product into contact with the rake plate to complete the correction and clamping. Then, driven by the top-push cylinder in the pre-placement component, the top-push plate can be used to correct the circuit board on the pre-placement table to avoid deviation affecting the feeding. The bearing station, together with the baffle, realizes automatic clamping and limiting of the circuit board to prevent rotational deviation from affecting processing. No manual operation is required, which greatly improves production efficiency, improves the accuracy of subsequent processing, and reduces the defect rate. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-8 In this embodiment, a tooling rotary table for a circuit board includes an operating table 1. From left to right, a conveyor table 2, a pre-placement component 4, a turntable 5, and a loading / unloading component 3 are installed on the operating table 1. The loading / unloading component 3 spans above the conveyor table 2, the pre-placement component 4, and the turntable 5. The pre-placement component 4 is located between the conveyor table 2 and the turntable 5. Four sets of bearing stations 6 are installed on the table surface of the turntable 5.

[0027] The above-mentioned loading and unloading components move the circuit boards on the conveyor table to the pre-placement components for pre-waiting and can perform calibration processing on the circuit boards. This allows the loading and unloading components to accurately remove the circuit boards and place them in the bearing station for positioning. The circuit boards are then processed by rotating the turntable, thereby achieving the goal of eliminating the need for manual operation, greatly improving production efficiency, and improving processing accuracy.

[0028] Figure 3-4 ,by Figure 3 As shown in the diagram, to achieve the positioning correction of the pre-placed circuit board, the pre-placement assembly 4 includes a pre-placement platform 41 fixed on the operating table 1 and a side plate 42 opposite to the left side of the pre-placement platform 41. A first strip plate 44 is slidably connected to the surface of the pre-placement platform 41, and a first rake plate 46 is fixedly covered above the first strip plate 44. Four protrusions are formed on the first rake plate 46. Four sets of first deflectors 45 are installed on the top of the first strip plate 44, which are respectively opposite to the protrusions on the first rake plate 46. The first deflectors 45 and the bottom limit sliding of the first rake plate 46 are mutually restrictive. The side plate 42 is equipped with a push cylinder 43, whose piston rod is opposite to the left end of the first plate 44. The right end of the first plate 44 is fixed with a first guide rod 49 that passes through the pre-placement platform 41. A first spring 410 is sleeved on the outside of the first guide rod 49. The two ends of the first spring abut against the groove of the pre-placement platform 41 and the first plate 44 respectively. The bottom of the pre-placement platform 41 is equipped with a push cylinder 47, whose piston rod is fixed with a rake-shaped push plate 48. The protruding end of the push plate 48 corresponds to the gap between the protruding plate of the first rake plate 46 and the first deflector plate 45.

[0029] The piston rod of the push cylinder is opposite to the left end of the first plate, and can actively push the first plate to slide to the right, so that the first pawl and the first rake plate move in opposite directions, thereby opening the placement area. After the circuit board is placed, the push cylinder retracts, and the two ends of the first spring sleeved on the outside of the first guide rod abut against the slide groove of the pre-placement platform and the first plate, respectively. When the push cylinder retracts, the spring force can drive the first plate to automatically reset, thereby driving the first pawl to move and push the circuit board to the left until it is in contact with the first rake plate. The piston rod of the push cylinder at the bottom of the pre-placement platform fixes the rake-shaped push plate, and its protruding end corresponds to the gap between the protruding plate of the first rake plate and the first pawl. When the push cylinder moves upward, the protruding end of the push plate can be inserted into the placement area, thereby pushing the circuit board along the placement area until it is in contact with the inner wall of the first rake plate to complete the correction of the pre-waiting circuit board, and at the same time facilitate the accurate transfer of the loading and unloading components to the carrying station.

[0030] like Figure 5-8 ,by Figure 5 As shown, the bearing station 6 includes four sets of carrier plates 61 fixed on the turntable 5 and four sets of support plates 68 fixed at the bottom of the turntable. The support plates 68 are respectively located below the corresponding carrier plates 61. A second plate 64 is slidably connected to the carrier plate 61. A second rake plate 62 covering the second plate 64 is fixed on the top. The second rake plate 62 has four protruding ends. Four sets of second lever plates 65 are fixed on the top of the second plate 64, which are respectively opposite to the protruding ends of the second rake plate 62. The second plate 64 is limited and slid at the bottom of the second rake plate 62. Two sets of top-feeding cylinders 614 are installed on the operating table 1. The piston rods of the two sets of top-feeding cylinders 614 are respectively opposite to the second plate 64 at the loading end and the second plate 64 at the unloading end. A second guide rod 66 is fixed to the end of the second plate 64 opposite to the piston rod of the top-feeding cylinder 614. The second guide rod 66 is limited and passes through the carrier plate 61. A second spring 67 located in the slide groove of the carrier plate 61 is sleeved on the outer side of the support plate 66 to form a reset structure. A second baffle 69 is slidably connected to the right side of the support plate 68. A second guide rod 66 is also limited and passed through the support plate 68. The top of the second guide rod 66 is fixed to the second baffle 69. The top of the second baffle 69 is higher than the top of the carrier plate 61. A second spring 67 is sleeved on the outer side of the second guide rod 66. A convex plate 611 that slides inside the support plate 68 is fixed on the left side of the second baffle 69. An upper cylinder 612 located below the turntable 5 is fixed on the table surface of the operating table 1. A pressure plate 613 is installed at its top end, corresponding to the top of the convex plate 611. Four sets of slide grooves are opened at the bottom of the carrier plate 61. Four second guide rods 66 extending into the slide grooves are limited and passed through the left side. An L-shaped moving plate 610 that slides with the turntable 5 is fixed at one end of each second guide rod 66 in the slide groove. Its right side is in contact with the second baffle 69.

[0031] The top-feeding cylinder pushes the corresponding second plate to slide on the carrier plate while squeezing the second spring, causing the second pawl to move along the bottom of the second rake plate. This opens the placement area on the carrier plate, facilitating the loading and unloading assembly to put in and take out the circuit board. When the top-feeding cylinder retracts, the second spring provides a restoring force, causing the second plate to automatically return to its original position. This, in turn, causes the second pawl to clamp and fix the circuit board, while simultaneously correcting its position. At the same time, the moving plate provides bottom support for the circuit board, and the second baffle limits one side of the circuit board, thus preventing the circuit board from shifting during the turntable rotation and affecting subsequent processing. Meanwhile, the top-feeding cylinder drives the pressure plate, which, through the convex plate, moves the second baffle down to halfway down the moving plate. The moving plate is then pushed by external equipment, and the corresponding second guide rod moves together, squeezing the second spring. This allows the bottom part of the circuit board to protrude, facilitating the corresponding processing.

[0032] The top of the second rake plate 62 is fixed to the first baffle 63 by screws. The first baffle 63 has four sets of waist holes, and one point of the first baffle 63 forms an L-shaped protrusion that extends to the placement area on the carrier plate 61. Therefore, the first baffle can be adjusted to a suitable position according to the size of the circuit board, which is convenient for limiting the circuit board in conjunction with the second baffle.

[0033] The working principle of the above embodiments is as follows:

[0034] The conveyor table moves the circuit board to the designated position, and the loading and unloading assembly moves the circuit board to the pre-placement table. Simultaneously, a push cylinder pushes out, propelling the first plate. The first plate moves the first guide plate and the first guide rod synchronously, simultaneously compressing the first spring. After the circuit board is placed, the push cylinder retracts, and the first spring releases its elasticity, pushing the first plate forward. Therefore, the first guide plate moves accordingly, working in conjunction with the corresponding first rake plate's protruding end to push and clamp the circuit board. Then, the push cylinder drives the push plate to push in, bringing the product closer to the first rake plate, thus completing the alignment of the circuit board. In principle, when the loading and unloading assembly moves the circuit board onto the carrier plate, the top-feeding cylinder pushes out and pushes the corresponding second plate. At the same time, the corresponding second guide rod moves and also compresses the second spring, causing the second deflector plate and the second rake plate to move in opposite directions to open the placement area. After the circuit board is placed, the first baffle plate and the second baffle plate act as upper and lower limits. Then the top-feeding cylinder resets, and the second spring resets. The second plate can drive the second deflector plate and the second rake plate to clamp and fix the circuit board. Therefore, it can limit the four sides of the circuit board and effectively prevent the deviation during rotation from affecting subsequent processing.
