Description

Technical Field

[0001] The utility model relates to the technical field of alloy resistor production, in particular to a fully automatic conveying sandblasting machine. Background Technique

[0002] An alloy resistor refers to a resistor that uses an alloy as the current medium, and has the characteristics of low resistance value, high precision, low temperature coefficient, impact current resistance, high power, etc., and is widely used in precision instruments, military products, aerospace electronics, new energy photovoltaic products, automobiles, etc.

[0003] The production process of alloy resistors is generally divided into steps such as blanking and stamping, laser trimming, epoxy encapsulation, removal of encapsulation runners, surface sandblasting, character code printing, curing, granulation, etc. Among them, in the surface sandblasting work, it is necessary to perform double-sided sandblasting on the products on the strip, and currently, the masking sandblasting work is basically carried out by relying on jigs.

[0004] For example, the Chinese patent of the prior art CN213970678U discloses a sandblasting mold for alloy resistors, including: an upper jig unit and a lower jig unit, the upper jig unit and the lower jig unit are detachably connected, the upper jig unit includes an upper jig plate, positioning holes, an upper sandblasting groove, and upper sandblasting bars, the positioning holes are arranged around the upper jig plate, and the upper sandblasting groove is arranged on the upper jig plate.

[0005] However, there are many inconveniences in the use of the mold in the above prior art. After completing the single-sided sandblasting treatment of the products on the strip, it is necessary to open the profiling jig and the cover plate to turn over the strip therein, and then reassemble the profiling jig and the cover plate to perform the sandblasting treatment on the other side of the products on the strip. The process of completing double-sided sandblasting is cumbersome, and the sandblasting work mainly relies on manual operation, with low work efficiency and low automation degree. Content of the Utility Model

[0006] In view of this, the purpose of the present utility model is to provide a fully automatic conveying sandblasting machine, which can improve the sandblasting efficiency and has a high degree of automation.

[0007] To achieve the above purpose, the present utility model adopts the following content:

[0008] A fully automatic conveying sandblasting machine provided by the present utility model includes a frame and a sandblasting machine above it. Two conveying lines that are parallel to each other, arranged side by side and have opposite conveying directions are further arranged on the frame, and the middle parts of the two conveying lines both pass under the sandblasting machine;

[0009] A support frame is also provided on one side of the frame, and two side-by-side silos and a lifting assembly corresponding to each silo are provided on the surface of the support frame. The silos are connected to the end of the conveyor line, and the lifting assembly is used to transport the materials in the silos up and down to approach or move away from the conveyor line; a pushing assembly located just above the silo is provided at the end of one of the conveyor lines to push the top material in the silo horizontally onto the conveyor line;

[0010] The frame is also provided with a turning-over transfer assembly located in the middle of the ends of the two conveyor lines. The turning-over transfer assembly and the two silos are located at the two ends of the conveyor lines respectively. The turning-over transfer assembly is used to rotate the material on one conveyor line 180° and turn it over and transfer it to another conveyor line.

[0011] According to a fully automatic conveyor-type sandblasting machine provided by the utility model, the material bin is divided into two rows of material troughs on the left and right; the two material bins are guided and translated on the support frame by the slide rail slider assembly, and the support frame is also provided with two groups of horizontal displacement modules for controlling the movement of the respective material bins. In this way, the horizontal displacement module realizes the left and right translation movement of the material bin to achieve the purpose of switching the left and right material troughs. By adding material troughs in the material bin to control the production efficiency, the storage capacity of the material bin is increased, and it has a larger volume, which can store a large amount of materials, meet the needs of large-scale production and storage, and facilitate assembly line production.

[0012] Furthermore, the lifting assembly is located outside the silo, and includes a vertical displacement module disposed on the support frame and a lifting plate connected to the output end of the vertical displacement module, and the lifting plate is placed in the silo. Thus, the vertical displacement module controls the lifting plate to move up and down, and the lifting plate realizes the action of connecting the material with the end of the conveyor line.

[0013] Furthermore, the pusher assembly includes a frame-shaped bracket extending outward from one of the ends of the conveyor line, the upper parts of both sides of the inner wall of the frame-shaped bracket extend inward to form a blocking edge, and a horizontal pusher cylinder is provided on one side of the top of the frame-shaped bracket through a mounting plate, and the output end of the pusher cylinder is connected to a vertical pusher plate outward. In this way, the lifting plate is first controlled by the vertical displacement module to lift the material to the conveying plane height of the conveyor line, at which time the top material is limited by the blocking edge, and then the pusher cylinder controls the pusher plate to be pulled back inward, and during the retraction of the pusher plate, the top material is horizontally pushed inward to the surface of the conveyor line to complete the loading action.

[0014] Furthermore, the bottom end of the push plate is slightly lower than the horizontal base surface where the blocking edge is located. In this way, it is ensured that only the uppermost material can be driven to move during the retraction of the push plate, and the cyclic material distribution action of the stacked material layers in the silo is perfectly realized.

[0015] According to a fully automatic conveyor type sandblasting machine provided by the present utility model, the turning and transferring assembly includes a turning frame arranged on the frame. A rotary cylinder is arranged at the top of the turning frame. A swing arm is arranged at the output end of the rotary cylinder. A transfer plate perpendicular to the swing arm is arranged at the other end of the swing arm. Electromagnets are arranged on the surface of the transfer plate. In this way, the rotary cylinder controls the swing arm to drive the transfer plate to turn back and forth left and right, and the electromagnets on the transfer plate suck the materials on one of the conveyor lines. After the transfer plate is horizontally turned, the electromagnets stop working. At this time, the turned-over materials fall onto the other conveyor line.

[0016] Further, oil pressure buffers are symmetrically arranged on both sides of the turning frame, and the oil pressure buffers are on the rotation path of the swing arm. The oil pressure buffers are used to effectively stop the swing arm in the rotation movement, so that the swing arm stops at the set position.

[0017] Wherein, a plurality of moving casters are installed at the bottom end surface of the support frame body. In this way, it is convenient for personnel to quickly move the support frame body, so that the support frame body is close to the conveyor line or separated from the conveyor line, reducing the waste of manpower and time.

[0018] Compared with the prior art, the present utility model has the following technical effects: The structure of the present utility model is simple and reasonably designed; it can not only complete the automatic feeding of the sandblasting jig, but also perform a 180° turning operation on the sandblasting jig that has completed the single-sided sandblasting treatment of the workpiece, which is convenient for subsequent sandblasting treatment of the other side of the workpiece. Finally, the sandblasting jigs that have completed the double-sided sandblasting work of the workpiece are centrally collected, and then the workpieces can be taken out by manually disassembling the sandblasting jigs; the sandblasting machine of the present utility model does not require manual loading, unloading and turning operations, has a high degree of automation, high work efficiency, strong practicability and is easy to promote.

Detailed implementation mode

[0025] In order to more clearly illustrate the present utility model, the following further describes the present utility model in conjunction with preferred embodiments. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not be used to limit the protection scope of the present utility model.

[0026] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] Please refer to Figures 1 to 4 As shown in the figure. An embodiment of the present utility model provides a fully automatic conveyor - type sandblasting machine, which mainly includes a frame 1 and a sandblasting machine 2 above it. There is a spacing between the sandblasting working end of the sandblasting machine 2 and the frame 1. On the frame 1, there are also two conveyor lines 3 arranged in parallel side by side and with opposite conveying directions, and the middle parts of both conveyor lines 3 pass under the sandblasting machine 2. The conveyor line adopts a common belt conveyor line in industrial production.

[0028] On one side of the frame 1, a support frame 4 is also provided. On the surface of the support frame 4, there are two side - by - side silos 5 and lifting components 6 respectively corresponding to and cooperating with one silo 5. The silo 5 is connected to the end of the conveyor line 3, and the lifting component 6 is used to vertically transport the materials in the silo 5 to approach or move away from the conveyor line 3; at the end of one conveyor line 3, there is a pushing component 7 located directly above the silo 5 to horizontally push the uppermost material in the silo 5 onto the conveyor line 3.

[0029] Among them, the frame 1 is also provided with a turning transfer assembly 8 located in the middle position between the ends of the two conveyor lines. The turning transfer assembly 8 and the two silos 5 are respectively located at the two ends of the conveyor line 3. The turning transfer assembly 8 is used to rotate the material on one conveyor line 180° and turn it over and transfer it to another conveyor line.

[0030] During actual operation, the material in one side of the silo is lifted to the working area of ​​the pushing component by the corresponding lifting component, and the pushing component pushes the material and sandblasting fixture at the top of the silo to one of the conveyor lines, and then the conveyor line conveys it to the bottom of the sandblasting machine for single-sided sandblasting. After that, the material after single-sided sandblasting is rotated 180° by the turning transfer component and transferred to another conveyor line, and then conveyed in the opposite direction by this conveyor line to the bottom of the sandblasting machine for sandblasting on the other side. Finally, the material that has completed double-sided sandblasting is taken over by the lifting component and collected in the silo on the other side. The above process is repeated to realize double-sided sandblasting of the batch assembly line.

[0031] In one embodiment, the silo 5 is divided into two rows of troughs 51 on the left and right. Of course, more troughs can be added to the silo according to needs. Both silos 5 are guided and translated on the support frame 4 by the slide rail slider assembly 41. The support frame 4 is also provided with two sets of horizontal displacement modules 42 for controlling the movement of the respective silos. In this way, the horizontal displacement module realizes the left and right translation movement of the silo to achieve the purpose of switching the left and right troughs. By adding troughs in the silo to control the production efficiency, the storage capacity of the silo is increased, and it has a larger volume, which can store a large amount of materials, meet the needs of large-scale production and storage, and facilitate assembly line production.

[0032] The lifting assembly 6 is located outside the silo 5, and includes a vertical displacement module 61 disposed on the support frame 4 and a lifting plate 62 connected to the output end of the vertical displacement module 61, and the lifting plate 62 is horizontally movable inwardly and placed in the silo 5. In this way, the vertical displacement module controls the lifting plate to move up and down, and the lifting plate realizes the action of connecting the material with the end of the conveyor line.

[0033] The pusher assembly 7 includes a frame bracket 71 extending outward from the end of one of the conveyor lines, the upper parts of the inner walls of the frame bracket 71 extend inward to form blocking edges 72, and a horizontal pusher cylinder 74 is provided on one side of the top of the frame bracket 71 through a mounting plate 73, and the output end of the pusher cylinder 74 is connected outward to a vertical pusher plate 75. In this way, the lifting plate is first controlled by the vertical displacement module to lift the material to the conveying plane height of the conveyor line, at which time the top material is limited by the blocking edge, and then the pusher cylinder controls the pusher plate to be pulled back inward, and during the retraction of the pusher plate, the top material is horizontally pushed inward to the surface of the conveyor line to complete the loading action.

[0034] It should be noted that the bottom end of the pusher plate 75 is slightly lower than the horizontal base surface where the blocking edge 72 is located, and does not exceed the thickness of a sandblasting jig. In this way, it is ensured that only the topmost material can be driven during the retraction of the pusher plate, perfectly realizing the cyclic material distribution action of the stacked material layers in the silo.

[0035] In this embodiment, the turning and transferring assembly 8 includes a turning frame 81 arranged on the frame 1. A rotary cylinder 82 is arranged at the top of the turning frame 81. A swing arm 83 perpendicular to the output end of the rotary cylinder 82 is arranged at the output end of the rotary cylinder 82. A transfer plate 84 perpendicular to the swing arm 83 is arranged at the other end of the swing arm 83. An electromagnet 85 is arranged on the surface of the transfer plate 84. In this way, the rotary cylinder controls the swing arm to drive the transfer plate to turn left and right back and forth, and the electromagnet on the transfer plate sucks the materials on one of the conveying lines. After the transfer plate is horizontally turned over, the electromagnet stops working. At this time, the turned-over materials will fall steadily onto the other conveying line.

[0036] Among them, oil pressure buffers 86 are symmetrically arranged on both sides of the turning frame 81. The oil pressure buffers 86 are on the rotation path of the swing arm 83. The oil pressure buffers are used to effectively stop and balance the swing arm during the rotation action, so that the swing arm stops at the set position accurately.

[0037] Among them, a number of moving casters 43 are installed on the bottom end surface of the support frame body 4. In this way, it is convenient for personnel to quickly move the support frame body, so that the support frame body is close to or separated from the conveying line, reducing the waste of manpower and time.

[0038] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
