[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0027] like Figures 1 to 3As shown, an embodiment of the utility model provides a cutting device 1, comprising a material placing tray 11 for placing devices to be cut, a shearing assembly 12, a clamping assembly 13 and a frame 14; the material placing tray 11 is arranged on the frame 14, and clamping assemblies 13 are arranged on both sides of the frame 14, so that the clamping assembly 13 can clamp the two ends of the material placing tray 11 when performing a cutting operation; at least one group of first through hole arrays 111 is provided on the material placing tray 11, for inserting the pins of the devices to be cut; the shearing assembly 12 comprises a linear drive module 121 arranged at one end of the frame 14 away from the material placing tray 11, and a cutter 122 connected to the linear drive module 121, the cutter 122 is in contact with the bottom surface of the material placing tray 11 toward one side of the material placing tray 11, and the cutter 122 reciprocates along the length direction of the frame 14, so that the cutter 122 cuts part of the pins inserted in the first through hole array 111.

[0028] By inserting the pins of the components into the first through-hole array 111, the components to be cut are stably inserted on the material tray 11; the cutter 122 is in contact with the bottom surface of the material tray 11 on one side facing the material tray 11, and the cutter 122 is reciprocated along the length direction of the frame 14 through the linear drive module 121, so that the cutter 122 cuts the pins inserted in the first through-hole array 111, so that the pins of different components can be cut to the required uniform length, thereby improving the yield rate of the cutting operation. In addition, the clamping assembly 13 arranged on both sides of the frame 14 can ensure that the material tray 11 maintains a good position stability during the cutting operation, so as to maintain the position stability of the components to be cut, thereby reducing the processing error of the cutter 122 during cutting, thereby improving the yield rate of the cutting operation.

[0029] It should be noted that the first through hole array 111 is formed by at least two through holes arranged in an array. In actual production applications, the number and size of through holes, as well as the array arrangement of through holes, need to be selected according to the actual setting of the pins of the device to be cut.

[0030] In an alternative embodiment, see Figure 1 The end of the cutter 122 is provided with a snap-fitting slot 1221, and the transmission shaft of the linear drive module 121 is snap-fitted into the snap-fitting slot 1221, so that the cutter 122 forms a transmission connection with the linear drive module 121. This arrangement ensures that the cutter 122 and the linear drive module 121 form a good connection strength, and it is convenient for the operator to replace the worn or damaged cutter 122 as needed, so that the cutting device 1 can quickly meet different processing requirements and has good applicability.

[0031] Furthermore, if Figure 2As shown, the placing tray 11 is provided with a placement groove 112 for placing the components to be cut, and the first through hole array 111 is located at the bottom of the placement groove 112. The placement groove 112 can quickly locate and limit the components to be cut as a whole, which is convenient for placing and positioning the components to be cut. Through the cooperation of the placement groove 112 and the first through hole array 111, the position stability of the components to be cut can be maintained during the cutting operation, thereby reducing the processing error of the cutter 122 during cutting, thereby improving the yield rate of the cutting operation.

[0032] It should be noted that the placement groove 112 and the first through hole array 111 on the discharge tray 11 need to be set according to the specifications of the components to be cut. According to the production line processing requirements, multiple discharge trays 11 of different specifications can be processed according to the specifications of the components to be cut, and the discharge tray 11 can be replaced according to the processing conditions to meet different processing requirements.

[0033] In an optional embodiment, a plurality of placement slots 112 are provided on the material placing tray 11, and a first through hole array 111 is provided at the bottom of each placement slot 112. A plurality of placement slots 112 and a first through hole array 111 may be arranged in parallel on the material placing tray 11, so that the material placing tray 11 may simultaneously place a plurality of components to be cut, so that the cutting device 1 may simultaneously cut the pins of a plurality of components to be cut, thereby improving the production and processing efficiency of the cutting device 1.

[0034] Further, see Figure 1 and Figure 3 The frame 14 is provided with a guide base plate 151 corresponding to the cutter 122, and guide rails 152 provided on opposite sides of the guide base plate 151, so that the cutter 122 slides along the guide groove formed by the guide base plate 151 and the guide rails 152. This arrangement can limit the movement trajectory of the cutter 122 to ensure the movement consistency of the cutter 122 during the cutting operation, thereby ensuring that the cutter 122 can cut the pins of different components to the required uniform length, thereby improving the yield rate of the cutting operation.

[0035] Specifically, Figure 3 and Figure 7As shown, the plane where the material discharging tray 11 is located is parallel to the plane where the guide bottom plate 151 is located, and the plane where the cutter 122 is located forms an angle with the horizontal plane, which is an acute angle. A notch 16 is formed between the end of the guide bottom plate 151 and the frame 14, so that the cut pins can slide down from the notch 16. This arrangement can make the cut pin waste slide to the notch 16 through the guide bottom plate 151 under the action of gravity, so that there is no need to set up an additional conveying device for transporting the pin waste, so as to simplify the structure of the cutting device 1 and reduce the production and maintenance costs of the cutting device 1. In addition, this method can also clean up the generated pin waste in time, avoid stopping the cutting device 1 for cleaning due to the accumulation of pin waste, so as to ensure the continuity of normal production operations and improve the production efficiency of cutting operations.

[0036] It should be noted that the plane where the discharge tray 11 is located, the plane where the guide bottom plate 151 is located, and the plane where the cutter 122 is located are parallel to each other.

[0037] In actual production applications, different forms of waste collection devices such as a waste collection tray, a waste collection basket or a waste collection basin can be set under the gap 16, and the pin waste in the waste collection device can be cleaned by manual regular replacement.

[0038] In an optional embodiment, the angle formed by the plane where the cutter 122 is located and the horizontal plane can be 15°, 30°, 45°, 60°, etc.

[0039] Further, see Figure 3 The cutting device 1 further comprises a guide plate 17, which is arranged at the bottom of the frame 14 and is arranged corresponding to the discharge tray 11, so that the cut tube pins slide toward the guide plate 17. The guide plate 17 can guide the cut tube pin waste into different forms of waste collection devices such as a waste collection tray, a waste collection basket or a waste collection basin, so as to avoid the waste from causing pollution and safety hazards to the production environment, making the entire cutting operation more green and environmentally friendly.

[0040] Specifically, Figure 4 As shown, the guide plate 17 includes a connection portion 171 connected to the frame 14, and a guide portion 172 connected to the connection portion 171, so that the cut pins are away from the cutting device along the guide portion 172. This arrangement can ensure that the guide plate 17 and the frame 14 are firmly connected, while keeping a certain angle between the plane where the guide portion 172 is located and the horizontal plane, so as to facilitate the collection of waste pins.

[0041] In actual production applications, the guide portion 172 can be aligned with different forms of waste collection devices such as a waste collection tray, a waste collection basket or a waste collection basin. By providing the guide plate 17, the placement of the waste collection device is more flexible and convenient, and is not limited by the position of the cutting device 1, so that the entire cutting operation has better production continuity.

[0042] Further, see Figure 1 , Figure 3 and Figure 6 The frame 14 includes side baffles 141 arranged at intervals, and a bottom plate 142 connected to the side baffles 141. The clamping assembly 13 includes a linear motion module 131 connected to the side baffles 141, and a clamping piece 132 connected to the linear motion module 131; the linear motion module 131 reciprocates in a linear motion in a direction perpendicular to the plane where the discharge tray 11 is located, so that the clamping piece 132 approaches or moves away from the discharge tray 11.

[0043] The side baffles 141 and the bottom plate 142 cooperate to form a protective shell on the frame 14, thereby protecting the internal components of the cutting device 1. The clamping member 132 can ensure that the material tray 11 maintains good position stability during the cutting operation, so as to maintain the position stability of the components to be cut, thereby reducing the processing error of the cutter 122 during cutting, thereby improving the yield rate of the cutting operation.

[0044] In actual production applications, the cutting device 1 can be connected to a workstation or other fixed plane via the bottom plate 142 ; wherein the plane where the bottom plate 142 is located is kept parallel to the horizontal plane to facilitate the installation and fixation of the bottom plate 142 .

[0045] In actual production applications, the material tray 11 on which the components to be cut are placed can be first connected to the frame 14, and then the clamping piece 132 can be moved towards the direction close to the material tray 11 under the action of the linear motion module 131, until the clamping piece 132 abuts against the material tray 11, so that the material tray 11 can maintain good position stability under the action of the clamping piece 132, and then the cutting operation can be carried out; when the material tray 111 needs to be replaced, the clamping piece 132 can be moved towards the direction away from the material tray 11 under the action of the linear motion module 131, until the clamping piece 132 is away from the material tray 11 to a certain distance, and then the material tray 11 can be taken and replaced.

[0046] In an alternative embodiment, Figure 3 , Figure 6 and Figure 7As shown, a shielding plate 18 is provided at one end of the frame 14 close to the material discharging tray 11, and the shielding plate 18 is connected to the end of the side baffle 141. The shielding plate 18 can prevent the cut waste pins from splashing out of the cutting device under the action of shear force, which not only facilitates the collection and processing of the waste pins, but also prevents the operator from being injured by the splashing waste pins, thereby improving the production safety of the cutting device.

[0047] Specifically, see Figure 5 The pressing member 132 includes a connecting arm 1321 connected to the linear motion module 131 , and a pressing head 1322 connected to the end of the connecting arm 1321 .

[0048] In an optional embodiment, two clamping assemblies 13 respectively arranged on both sides of the frame 14 are located at the diagonal sides of the material placing tray 11, so that the two clamping heads 1322 respectively clamp the two diagonal sides of the material placing tray 11 during the cutting operation. This arrangement improves the position stability of the material placing tray 11 during the cutting operation, so that the position stability of the components to be cut is better, thereby reducing the processing error of the cutter 122 during cutting, thereby improving the yield rate of the cutting operation.

[0049] In an alternative embodiment, Figure 6 As shown, a protective plate 19 is provided on the upper cover of the frame 14, and the protective plate 19 is located between the discharge tray 11 and the linear drive module 121, and the opposite sides of the protective plate 19 are in contact with the side baffles 141, so that the protective plate 19 and the discharge tray 11 cover the movement area of ​​the cutter 122. This arrangement can prevent the operator from directly contacting the cutter 122 during the work process, thereby avoiding production safety accidents such as operator injuries caused by contacting the working cutter 122, so as to improve the production safety of the cutting equipment.

[0050] In actual production applications, the linear drive module 121 and the linear motion module 131 can both use drive motors, cylinders, etc. Under the premise of not affecting the performance of the linear drive module 121 and the linear motion module 131, the embodiments of the present application do not limit the specific forms of the linear drive module 121 and the linear motion module 131.

[0051] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
