Description

[Technical field]

[0001] The invention relates to the technical field of chip-type electronic component processing, in particular to a cutting machine for chip-type electronic components. [Background technology]

[0002] Chinese invention patent application number 201920410926.6, publication number CN210453274U, application date 20190328, specifically discloses an automatic cutting machine, which includes a body structure, a carrier, a detection and positioning mechanism, a cutting mechanism, a control system and two guide rails and other components. It lowers the center of gravity of the carrier and the load-bearing plate, reduces the front and rear pitch torque, improves the operating accuracy and service life, and achieves precise adjustment of the pressure of the tool matrix to meet the use requirements of different ceramic diaphragms, prevent the ceramic diaphragms from being crushed, and at the same time improves the stability of product cutting and ensures the cutting quality.

[0003] However, the silo of the cutting machine is a fixed structure. When placing materials, the machine needs to be stopped, and then the materials are held and placed in the silo. This method has the following disadvantages:

[0004] 1. The internal space of the machine is limited and inconvenient to operate;

[0005] Second, putting your hands into the internal processing area of ​​the machine will undoubtedly create a safety hazard. If the operation is not done properly, the worker is likely to be injured. Therefore, in order to avoid injury to the worker when adding materials and to facilitate operation, the machine needs to be stopped, which will undoubtedly delay a certain amount of time.

[0006] 3. The cutting machine has no correction equipment when loading materials, and only relies on the stacking effect when placing materials. During the processing, since the chip resistor components are very thin and light, they are easy to move and cause position deviation, which will affect the cutting accuracy and ultimately lead to a high scrap rate. [Summary of the invention]

[0188] In the description of the present invention, it is necessary to understand that the description indicating the orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention.

[0189] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0190] The overall concept of the present invention is as follows:

[0191] (1) The uncut chip electronic components are sucked from the hopper 108 by the sucking device on the first lifting mechanism 111 and placed on the preheating heating plate 122. Then, the chip electronic components are pushed synchronously on four sides by the four correction plates 117, so that the position of the chip electronic components is re-corrected for the sucking device 109 connected to the first lifting mechanism 111 to suck the materials, thereby ensuring the consistency of the position of the materials sucked each time, thereby improving the cutting accuracy and reducing the scrap rate.

[0192] (2) The correction plate 117 is arranged at the longitudinal rear of the first transverse driving device 110. The purpose of such arrangement is to reduce the transverse length of the whole machine and utilize the longitudinal space of the machine.

[0193] (3) A heating rod 121 and a vacuum air path are disposed above the rectangular support plate 114. The heating rod 121 can preheat the calibrated chip electronic components to facilitate subsequent cutting. The vacuum air path can adsorb and fix the calibrated chip electronic components during transportation, thereby preventing the calibrated position from deviating during transportation.

[0194] (4) The material bin 108 can move horizontally and longitudinally, so that when loading materials or taking out cut products, the material support plate 1084 can be pulled out of the machine without reaching into the machine. This allows the machine to replace materials while the machine is in standby or non-stop mode, and can replenish materials when the last piece of material is cut, making full use of the time difference.

[0209] The first suction plate 1091 is provided with a first vent hole 10911 ; the bottom surface of the first suction plate 1091 is in contact with the material, and the first vent hole 10911 evacuates air from the contact surface to form a vacuum, thereby adsorbing the material.

[0210] At least one second air vent 10921 is provided on the second suction plate 1092; the diameter of the second air vent 10921 is greater than the diameter of the first air vent 10911; the second air vent 10921 is used to connect with a suction device, and in an embodiment of the present invention, is airtightly connected with the vacuum logic valve, so that the air sucked by the suction device is transferred to the air cavity through the second air vent 10921 and then to the first air vent 10911.

[0211] The second suction plate 1092 is connected to the top surface of the first suction plate 1091, and at least one air cavity is formed between the bottom surface of the second suction plate 1092 and the top surface of the first suction plate 1091, and the second vents 10921 are connected to the air cavities in a one-to-one correspondence, and each of the air cavities is connected to a plurality of the first vents 10911, and the sum of the cross-sectional areas of the plurality of the first vents 10911 corresponding to each air cavity is greater than the cross-sectional area of ​​the second vent 10921;

During vacuuming, since the vacuum logic valves 1093 are connected in parallel, when the first air hole 10911 corresponding to a vacuum logic valve 1093 and the material contact surface leak, the vacuum logic valve 1093 in the leaking state will not affect the vacuuming of the remaining vacuum logic valves 1093. The difference between it and a one-way valve is that the vacuum logic valve is not a one-way valve in the strict sense, and the vacuum logic valve has a rated air pressure, and the rated air pressure is greater than the atmospheric pressure, that is, when air is pumped out and leaks, the atmospheric pressure will not reverse the conduction of the vacuum logic valve, and when the air pressure blown in from the vacuum breaking valve 1094 is greater than the rated air pressure, the vacuum logic valve 1093 will be reversely conducted, so that the gas is blown from the vacuum logic valve 1093 to the first air hole 10911, separating the first suction plate 1091 from the material, that is, at this time the vacuum logic valve 1093 is in a vacuum breaking state.

It only needs to be convenient for reading, and there are no other special requirements for the installation position. The electronic pressure switch 1096 is existing and can be purchased directly on the market. The function of the electronic pressure switch 1096 is: to preset the vacuum degree of the suction device 1095, that is, when the electronic pressure switch 1096 reaches the predetermined pressure value, the surface will adsorb the material at this time, and it can be moved, which plays a role of safety protection, and at the same time it is convenient to adjust the vacuum degree of the vacuum to a suitable size. In specific use, the predetermined pressure can be determined through pre-debugging, so that the material can be adsorbed without causing the vacuum force to be too large, which will cause the surface of the material to be adsorbed and deformed, and then batch production and processing can be carried out.

[0334] Specific usage:

[0335] It also includes an alarm device 137, which is communicatively connected to the control device 102 for alarm prompts.

[0336] It also includes a photoelectric sensor 138, which is arranged on the outside of the two vertical support plates 123. The photoelectric sensor 138 is used to detect whether the material support plate 1184 and the chip electronic components stacked thereon are lifted to a predetermined position, so that each time the material support plate 1184 is lifted, the chip electronic components located on the top surface are lifted to the same position, which is convenient for the suction device 109.

[0337] It also includes a photoelectric sensor 139, which is fixedly connected to the first support frame 103, vertically facing downward and located directly above the preheating and heating plate 122 when the suction device 109 sucks the chip electronic components on the preheating and heating plate 122, and is used to detect whether the chip electronic components on the preheating and heating plate 122 that have been calibrated have stacking. The detection principle is that the thickness of the chip electronic components is known, and the height difference between the chip electronic components on the preheating and heating plate 122 and the photoelectric sensor 139 is pre-set and known. The photoelectric sensor 139 detects the height of the chip electronic components. If the height detected by the photoelectric sensor 139 is greater than the predetermined height, it means that there is stacking, which is fed back to the control device 102, and the control device 102 controls the alarm device 137 to issue an alarm prompt. If it is equal to, there is no problem with the surface, and the next action is continued; if it is less than, there is no chip electronic component on the surface. At this time, the detected height is the height of the preheating and heating plate 122, which is also fed back to the control device 102, and then the alarm device 137 is controlled to issue an alarm prompt.

[0338] For example, it is used to cut chip resistors and the processing program is preset. Of course, in other embodiments, it can also be used to cut chip capacitors and other products.

[0339] First, pull out the slide 1082, put the stacked chip resistors into the two limiting side plates 1083, and place them on the material support plate 1084; then push the slide 1082 back to its original position, at which time the lock 133 and the locking device 132 are locked with each other to fix the slide 1082 to prevent movement during the processing.

[0340] During processing, the control device 102 controls the driving motor 10851 to work according to a predetermined program, thereby driving the reducer 10852 to work, thereby driving the transfer support plate 1086 to rise, and lifting the material support plate 1084 and the chip resistor to a predetermined position to be detected by the photoelectric sensor 138. The photoelectric sensor 138 feeds back a signal to the control device 102. The control device 102 controls the driving motor 10851 to stop working, and controls the piston rod of the first lifting device 128 to extend downward to a predetermined position, thereby lowering the suction device 109 connected to the piston rod to a predetermined position to adsorb the chip resistor. After adsorption, the control device 102 can be preset to control the piston rod of the first lifting device 128 to reciprocate up and down several times, that is, to let the suction device 109 shake up and down several times, so that multiple chip resistors can be sucked up and shaken off as much as possible to avoid stacking. After shaking for a predetermined number of times, the control device 102 controls the piston rod of the first lifting device 128 to retract and return to its original position, thereby lifting the suction device 109 to a predetermined position.

[0341] Next, the control device 102 controls the first actuator 126 to work, and moves the transport platform where the correction plate 117 is located to be directly below the suction device 109 corresponding to the first lifting device 128. After it is in place, the control device 102 controls the first lifting device 128 to descend, and controls the suction device 109 to stop vacuuming, and at the same time blows air to break the vacuum of the suction device 109, and the chip resistor falls onto the preheating heating plate 122 to carry the chip resistor.

[0342] Then, the control device 102 controls the driving device 119 to work, drives the linkage mechanism 118 to move, and then drives the rotating shaft 1182 to rotate, thereby driving the four correction plates 117 to close synchronously to correct the position of the chip resistor.

[0343] After the calibration is completed, the control device 102 controls the first actuator 126 to reset the transport platform where the calibration plate 117 is located and move it to just below the photoelectric sensor 139. In this process, the control device 102 also controls the heating rod 121 to be powered on to preheat the chip resistor.

[0344] When the photoelectric sensor 139 detects the height of the chip resistor and it is inconsistent with the predetermined height, the control device 102 controls the alarm device 137 to issue an alarm prompt; only when the heights are consistent, the control device 102 controls the first motor 1101 to work, driving the first lifting mechanism 111 and its corresponding suction device 109 to move to the top of the preheating heating plate 122, ready to suck the chip resistor for loading.

[0345] After it is in place, the control device 102 controls the piston rod of the first lifting mechanism 111 to extend downward to a predetermined position, and then the control device 102 controls the suction device 109 corresponding to the first lifting mechanism 111 to vacuum and suck the chip resistor; after the suction is completed, for example, it can stop for several seconds, and when the time is up, it indicates that the suction is completed; then, the control device 102 controls the piston rod of the first lifting mechanism 111 to return to its original position and retract;

[0346] Next, the control device 102 controls the first motor 1101 to work, and drives the first lifting mechanism 111 to the top of the loading station corresponding to the carrier 106. At this time, the control device 102 can also control the carrier drive device 105 to work at the same time, and transport the carrier 106 to the rear predetermined loading station; after both are in place;

[0347] The control device 102 controls the piston rod of the first lifting mechanism 111 to move downward to a predetermined position. The control device 102 controls the suction device 109 to stop vacuuming and blows air to the suction device 109 to break the vacuum, so that the chip resistor falls off from the suction device 109 and is carried by the carrier 106.

[0348] The control device 102 controls the stage 106 to absorb the chip resistor, and the control device 102 controls the stage driving device 105 to move and reset, and transports the stage 106 to the bottom of the tool holder 104. Then the control device 102 controls the tool holder lifting device 131 and the stage driving device 105 to work according to a predetermined program to complete the cutting.

[0349] After the cutting is completed, for example, the number of cutting times can be preset, and when the preset number of cutting times is completed, it indicates that the cutting is completed.

[0350] Then, the control device 102 controls the stage driving device 105 to work, and transports the stage 106 backward to the predetermined loading station;

[0351] At this time, it also serves as a material unloading station, and the control device 102 controls the second motor 1121 to work, and moves the second lifting mechanism 113 and the corresponding suction device 109 to the top of the carrier 106;

[0352] After being in place, the control device 112 controls the piston rod of the second lifting mechanism 113 to extend downward to a predetermined position; then controls the suction device 109 to draw a vacuum to suck the cut chip resistor; after the suction is completed, controls the piston rod of the second lifting mechanism 113 to reset and retract; finally controls the second motor 1121 to move in the opposite direction, resets the second lifting mechanism 113 and the suction device 109 to be directly above another material bin 108; then controls the piston rod of the second lifting mechanism 113 to extend downward to place the cut chip resistor on the material support plate 1084 of another material bin 108. At this time, the control device 102 can also control the drive motor 10851 of another material bin 108 to work, and raise the material support plate 1084 to a predetermined position to receive the material. After completion, it can be lowered by the thickness of a chip resistor.

[0353] Whether the material in the silo 108 has been processed or fully stacked can be determined in a variety of ways. For example, the number of processing times can be preset, and a predetermined number of chip resistors can be stacked in advance. The number of processing times is equal to the number of stacks. When the corresponding number is reached, the control device 102 controls the alarm device 137 to issue an alarm prompt.
