Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to an automatic cutting device for plastic housings of electronic components. Background Technology

[0002] In the injection molding process of electronic components, the plastic shell is usually formed in one piece by a mold. The surface of the shell will have a gate for material injection, commonly known as a sprue. The sprue is a necessary runner structure in the injection molding process, but it must be completely removed after the product is molded and demolded, otherwise it will affect the subsequent assembly accuracy, electrical performance and appearance quality.

[0003] Currently, most small and medium-sized manufacturing enterprises still use manual hand-held scissors or diagonal pliers to cut sprues. Operators need to clamp each shell and cut manually, which is not only labor-intensive, but also results in uneven cuts, burrs, and cutting residue. In addition, this operation mode is inefficient, with long processing time per piece, and cannot match the high-speed cycle of modern injection molding production lines, thus forming a production bottleneck.

[0004] Therefore, it is necessary to design an automatic cutting device for plastic housings of electronic components. Utility Model Content

[0005] In order to overcome the shortcomings of uneven cuts and low efficiency in the existing manual cutting process of sprue, this utility model provides an automatic cutting device for plastic shells of electronic components.

[0006] The technical solution is as follows: An automatic cutting device for plastic housings of electronic components includes a frame, a controller, a partition, a pressure plate, a stop block, an elastic element, an electric push rod, a connecting frame, a cylinder, and a cutter. The frame is tilted forward as a whole. The controller is installed on the right side of the front part of the frame. A partition is fixedly connected to the middle of the frame, dividing the frame into two areas. The left side of the partition is the sprue collection area, and the right side is the finished product placement area. A pressure plate is slidably connected to the upper right side of the frame. The plate is located on the right side of the partition. A stop block is slidably connected to the front side of the pressure plate. The stop block is located between the pressure plate and the partition, and an elastic element is connected between the stop block and the pressure plate. In the initial state, the left side of the stop block abuts against the partition. An electric push rod is fixedly installed on the upper right side of the frame. The controller is electrically connected to the electric push rod. The telescopic end of the electric push rod is connected to the pressure plate. A connecting frame is fixedly connected to the upper left side of the frame. A cylinder is installed on the upper part of the connecting frame. A cutter is connected to the telescopic end of the lower part of the cylinder, and the cutter is located directly above the partition.

[0007] In one embodiment, a soft pad and a photoelectric sensor are also included. The soft pad is attached to the side of the pressure plate near the partition, and a photoelectric sensor is installed on the upper right side of the connecting frame. The photoelectric sensor is located directly above the finished product placement area and is electrically connected to the controller.

[0008] In one embodiment, the machine also includes a collection frame and a handle. The collection frames are slidably connected to the left and right sides of the front of the frame. The collection frames can be pulled out horizontally along the axial direction. The two collection frames are located in front of the sprue collection area and the finished product placement area, respectively. The front side of the collection frames is fixed with a handle.

[0009] In one embodiment, foot pads are also included, with multiple foot pads connected to the lower part of the frame.

[0010] In one embodiment, the blade of the cutter is made of cemented carbide.

[0011] In one embodiment, the frame is tilted forward at an angle of 15° to 30°, and the top placement area is a smooth material liner.

[0012] In one embodiment, a guide ramp is provided on the side of the stop block facing the pressure plate, and the ramp gradually slopes downward toward the partition.

[0013] Beneficial effects: 1. This utility model uses a stop block that slides to connect to the front side of the pressure plate and abuts against the partition to form a support platform. This can effectively support the plastic shell during the feeding stage and prevent it from falling off prematurely. At the same time, it serves as a front-end positioning reference to ensure that the shell is placed in the same position each time, which significantly improves the cutting accuracy and product consistency.

[0014] 2. This utility model uses a controller to uniformly control the electric push rod, cylinder and photoelectric sensor to realize the fully automated operation of "feeding - positioning - clamping - cutting - releasing - discharging", reducing manual intervention and increasing production efficiency.

Detailed Implementation

[0020] Example: An automatic cutting device for plastic housings of electronic components, such as... Figures 1-4 As shown, the machine includes a frame 1, a controller 2, a partition 3, a pressure plate 4, a stop block 6, an elastic element 7, an electric push rod 8, a connecting frame 9, a cylinder 10, and a cutter 11. The frame 1 is tilted forward at an angle of 15° to 30°, and its top placement area is lined with a smooth material. Gravity is used to achieve automatic feeding of the casing and automatic unloading of finished products, eliminating the need for additional power transmission. The structure is simple, energy-efficient, and highly effective. The controller 2 is installed on the front right side of the frame 1, and a partition 3 is fixedly connected to the middle of the frame 1. The partition 3 divides the frame 1 into two areas: the left side is the sprue collection area, and the right side is the finished product placement area. A pressure plate 4 is slidably connected to the upper right side of the partition 3. The pressure plate 4 is located to the right of the partition 3. A stop block 6 is slidably connected to the front side of the pressure plate 4. The stop block 6 is located between the pressure plate 4 and the partition 3, and an elastic element 7 is connected between the stop block 6 and the pressure plate 4. In the initial state, the left side of the stop block 6 abuts against the partition 3. A guide slope is provided on the side of the stop block 6 facing the pressure plate 4. The slope gradually slopes towards the partition 3 from top to bottom. The guide slope mainly cuts off the contact or friction transmission path between the plastic shell and the stop block 6, ensuring that the shell can still stay stably on the inclined liner after the stop block 6 is removed, and automatically slides down after the channel is fully opened. An electric push rod 8 is fixedly installed on the upper right side of the frame 1 by bolts. The controller 2 is electrically connected to the electric push rod 8. The telescopic end of the electric push rod 8 is connected to the pressure plate 4. A connecting frame 9 is fixedly connected to the upper left side of the frame 1. A cylinder 10 is installed on the upper part of the connecting frame 9. A cutter 11 is connected to the telescopic end of the lower part of the cylinder 10. The blade of the cutter 11 is made of hard alloy, which has strong cutting force and wear resistance, ensuring a flat cut. The cutter 11 is located directly above the partition 3.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes a soft pad 5 and a photoelectric sensor 12. The soft pad 5 is attached to the side of the pressure plate 4 near the partition 3 to achieve flexible pressing and avoid damaging the shell. The photoelectric sensor 12 is installed on the upper right side of the connecting frame 9. The photoelectric sensor 12 is located directly above the finished product placement area and is electrically connected to the controller 2.

[0022] like Figure 1 and Figure 4 As shown, it also includes a collection frame 13 and a handle 14. The collection frame 13 is slidably connected to the left and right sides of the front part of the frame 1. The collection frame 13 can be pulled out horizontally along the axis. The two collection frames 13 are located in front of the sprue collection area and the finished product placement area, respectively. The front side of the collection frame 13 is fixed with a handle 14, which facilitates quick cleaning of sprue waste and transfer of qualified finished products, and makes maintenance convenient.

[0023] like Figure 1 and Figure 4 As shown, it also includes foot pads 15. Multiple foot pads 15 are connected to the lower part of the frame 1 to enhance the stability of the equipment during operation and prevent the whole machine from shifting due to cutting vibration.

[0024] In actual use, the operator places the plastic shell with the sprue on the finished product placement area on the top right side of the frame 1. The frame 1 is tilted forward and the top is covered with a smooth material liner. The shell slides down automatically along the liner under gravity. When the shell slides to the bottom, its front end is blocked by the stop block 6 and stops moving. The stop block 6 is located between the pressure plate 4 and the partition 3. Its left side abuts against the partition 3 in the initial state to form a fixed limiting end face. Since the partition 3 divides the frame 1 into two independent areas, the main body of the shell is located in the finished product placement area on the right side of the partition 3, while the sprue part extends above the sprue collection area on the left side of the partition 3.

[0025] Subsequently, the operator activates the electric push rod 8 via the controller 2. The electric push rod 8 pushes the pressure plate 4 to move horizontally to the left. Since the left end of the stop block 6 is abutting against the partition 3 and cannot continue to move to the left, the pressure plate 4 will squeeze the elastic element 7 on the stop block 6 during its forward movement, causing it to be compressed and deformed. At the same time, the pressure plate 4 continues to move to the left, gradually clamping the plastic shell between the pressure plate 4 and the partition 3. During the clamping process, the soft pad 5 set on the inner side of the pressure plate 4 is in contact with the shell surface to achieve flexible pressing and prevent the shell surface from being crushed or deformed. At this time, the shell is clamped and fixed, and its sprue root is precisely aligned with the cutting position directly above the partition 3, ready for use.

[0026] Next, the photoelectric sensor 12 installed on the connecting frame 9 detects that the housing is fully in place and clamped, and then feeds the signal back to the controller 2. The controller 2 then starts the cylinder 10, which drives the cutter 11 to fall vertically and quickly to cut off the root of the sprue. After cutting, the separated sprue residue, because it is located on the left side of the partition 3, will fall directly into the sprue collection area below under the action of gravity, realizing automatic waste discharge, while the main housing is still clamped by the pressure plate 4 and retained on one side of the finished product placement area.

[0027] After cutting, cylinder 10 drives cutter 11 to rise and reset. Then controller 2 controls electric push rod 8 to retract, driving pressure plate 4 to move to the right. As pressure plate 4 moves to the right, the pressure on elastic element 7 on stop block 6 will be gradually released. Since the left side of stop block 6 is in contact with partition 3 in the initial state, in order to prevent stop block 6 from blocking the housing, electric push rod 8 will continue to retract to the set stroke. During this process, guide slope of stop block 6 begins to contact the housing. Due to the effect of slope, the housing will be subjected to an upward component force, causing it to be slightly lifted and separated from the surface of stop block 6, preventing the housing from moving horizontally under the action of friction or lateral pressure. Thus, the housing can "slip" down the slope under its own gravity, achieving active separation rather than passive dragging. Once the housing slides past the top of the slope, stop block 6 continues to move to the right until it is completely withdrawn. At this time, the housing is in an unconstrained state and then slides into the collection channel under the action of gravity, finally falling into the collection frame 13 set on the right, completing a complete automatic cutting and unloading cycle.
