Description

Technical Field

[0001] This utility model belongs to the field of wire harness production equipment technology, specifically relating to a fixture for opening a fuse box cover. Background Technology

[0002] Fuse boxes are used for general circuit protection and are widely used in the manufacturing of automobiles and electronic products. A fuse box is a specialized container for centrally storing fuses. Its core function is to provide overload protection by centrally storing fuses of different specifications. When the circuit current exceeds the rated value, the fuse melts and breaks the circuit, preventing wiring harness burnout or equipment damage.

[0003] A fuse box typically consists of a box body and a cover that rotates relative to the box body. The cover and box body are locked together by interlocking hooks. During the production of wire harnesses, the fuse box and wire harness need to be connected. Due to manufacturing processes, fuse boxes typically arrive with the box body and cover locked. To connect the wire harness, the fuse box cover needs to be manually opened, and after the wire harness is installed, the box body and cover need to be locked again to protect the wiring inside. Manually opening the fuse box cover is time-consuming, labor-intensive, and inefficient, and cannot meet the needs of mass production. Therefore, it is necessary to design a device that can replace manual opening of the fuse box cover to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture for opening a safe box cover, so as to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0006] A safety box cover opening fixture includes a feeding mechanism and a cover opening mechanism. The cover opening mechanism includes a frame, and a horizontally arranged turntable is rotatably provided at the top of the frame. Multiple positioning holes for accommodating safety boxes are provided through the end face of the turntable. The multiple positioning holes are evenly distributed along the circumference of the end face of the turntable.

[0007] A baffle is fixedly installed on the frame. The side of the baffle is engaged with the buckle of the safety box cover. A feeding port is provided through the frame. The safety box passes through the baffle and the feeding port as the turntable rotates.

[0008] As a further improvement, the turntable is rotatably connected to the frame via a rotating shaft. A first pulley is fixedly installed on the rotating shaft, and a first motor is fixedly installed at the bottom of the frame. A second pulley is fixedly connected to the output end of the first motor, and the first pulley and the second pulley are connected by a belt.

[0009] As a further improvement, the feeding mechanism includes a first channel, one end of which is connected to a vibratory feeder, and the other end of which is vertically connected to a second channel. The width of the first channel corresponds to the width of the safety box, and the width of the second channel corresponds to the length of the safety box.

[0010] As a further improvement, one end of the second channel is open at the bottom, with the opening located on the path of the positioning hole when the turntable rotates, and the other end of the second channel is provided with an ejection assembly.

[0011] As a further improvement, the ejection assembly includes a stop block and a push rod. The stop block is fixedly connected to the inner wall of the second channel, and the push rod is slidably engaged with the stop block. The axis of the push rod is parallel to the extension direction of the second channel, and a push plate is detachably connected to one end of the push rod. The push plate engages with the side wall of the safety box.

[0012] The other end of the push rod is fixedly mounted with a mounting base, and a roller is rotatably mounted on the mounting base.

[0013] As a further improvement, the ejection assembly also includes a second motor, the output end of which is fixedly mounted with a cam, and a roller is in rolling engagement with the outer wall of the cam.

[0014] As a further improvement, a compression spring is fitted onto the push rod, with one end of the compression spring fixedly connected to the side of the stop block and the other end of the spring fixedly connected to the mounting base.

[0015] Due to the adoption of the above technical solution, the beneficial technical effects of this utility model are as follows:

[0016] This utility model provides a fuse box cover opening fixture, which uses a baffle to apply resistance to the fuse box that rotates synchronously with the turntable, and opens the fuse box's latch, replacing manual operation and saving time and effort.

[0017] By setting up a feeding mechanism, the vibratory feeder adjusts the bulk safety boxes to a set position and continuously outputs them. The ejector component continuously pushes the safety boxes into the positioning holes of the turntable, replacing manual feeding and loading, thus improving work efficiency.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0026] like Figure 1-5 As shown, a safety box cover opening fixture includes a feeding mechanism 2 and a cover opening mechanism 1. The cover opening mechanism 1 includes a frame 101. A horizontally arranged turntable 102 is rotatably provided at the top of the frame 101. A plurality of positioning holes 103 for accommodating the safety box 4 are provided through the end face of the turntable 102. The plurality of positioning holes 103 are evenly distributed along the circumferential direction of the end face of the turntable 102.

[0027] A baffle 104 is fixedly installed on the frame 101. The side of the baffle 104 cooperates with the buckle 401 of the cover of the safety box 4. A discharge port 105 is provided through the frame 101. When the safety box rotates with the turntable 102, it passes through the positions of the baffle 104 and the discharge port 105.

[0028] In use, the safety box 4 is placed into the positioning hole 103 with the latch 401 facing upwards. As the turntable 102 rotates the safety box 4, the latch 401 undergoes elastic deformation after being blocked by the baffle 104, causing the barb between the box body and the lid to disengage, thus opening the safety box 4 lid. To ensure that the lid can be opened normally, the positioning hole 103 and the safety box 4 are fitted with a clearance in the length direction, and the highest point of the latch 401 of the safety box 4 is higher than the upper surface of the turntable 102.

[0029] Specifically, the positioning hole 103 consists of a first positioning hole and a second positioning hole that are interconnected. The body of the safety box 4 engages with the first positioning hole, which restricts the body of the safety box 4 from moving along its length. For example, utilizing the existing protrusions on the surface of the safety box 4, a corresponding groove is provided on the inner wall of the first positioning hole. The protrusions on the surface of the safety box 4 engage with the grooves on the inner wall of the first positioning hole, thus achieving the limitation of the body by the first positioning hole. The lid of the safety box 4 is clearance-fitted with the second positioning hole along its length, thereby allowing space for the lid to open. In practical applications, other effective measures can also be taken to restrict the movement of the body, which are not limited here.

[0030] As the turntable 102 continues to rotate, the safety box 4 slides out of the positioning hole 103 when it passes the discharge port 105 of the frame 101. In actual use, a material box is placed below the discharge port 105 to store the safety box 4.

[0031] In this embodiment, the turntable 102 is rotatably connected to the frame 101 via a rotating shaft. A first pulley is fixedly mounted on the rotating shaft. A first motor 106 is fixedly mounted at the bottom of the frame 101. A second pulley is fixedly connected to the output end of the first motor 106. The first pulley and the second pulley are connected by a belt. The first motor 106 is used to drive the turntable 102 to rotate.

[0032] In this embodiment, the feeding mechanism 2 includes a first channel 201, one end of which is connected to a vibratory feeder 202, and the other end of which is vertically connected to a second channel 203. The width of the first channel 201 corresponds to the width of the safe box 4, and the width of the second channel 203 corresponds to the length of the safe box 4.

[0033] The vibratory feeder 202 is a conventional feeding device in the prior art, and its structure will not be described in detail. The function of the vibratory feeder 202 is to uniformly output the originally scattered safety boxes 4 in a specific posture. Both the first channel 201 and the second channel 203 allow a maximum of one safety box 4 to pass through at the same time in the width direction.

[0034] In this embodiment, one end of the second channel 203 is open at the bottom, and the opening is located on the path traversed by the positioning hole 103 when the turntable 102 rotates. The other end of the second channel 203 is provided with an ejector component 3, which is used to push the safety box 4 to move until the safety box 4 is pushed to the opening. Under the action of gravity, the safety box 4 falls into the positioning hole 103 of the turntable 102.

[0035] In this embodiment, the ejection assembly 3 includes a stop block 301 and a push rod 302. The stop block 301 is fixedly connected to the inner wall of the second channel 203. The push rod 302 is slidably engaged with the stop block 301. The axis of the push rod 302 is parallel to the extension direction of the second channel 203. One end of the push rod 302 is detachably connected to a push plate 303, which engages with the side wall of the safety box 4. The other end of the push rod 302 is fixedly mounted with a mounting base 304, and a roller 305 is rotatably mounted on the mounting base 304.

[0036] The stop block 301 is used to limit the movement trajectory of the push rod 302, and the push plate 303 contacts the side wall of the fuse box 4 and pushes the fuse box 4 to move.

[0037] In this embodiment, the ejection assembly 3 also includes a second motor 307, which is fixedly mounted on a motor mounting base. A cam 308 is fixedly mounted on the output end of the second motor 307, and a roller 305 rolls with the outer wall of the cam 308. The second motor 307 drives the cam 308 to rotate, and the cam 308 drives the push rod 302 to move horizontally, thereby pushing the safety box 4 to move.

[0038] In this embodiment, a compression spring 306 is sleeved on the push rod 302. One end of the compression spring 306 is fixedly connected to the side of the stop block 301, and the other end of the compression spring 306 is fixedly connected to the mounting base 304. Figure 4 As shown, after the push rod 302 moves to the left and pushes the safety box 4 into the positioning hole 103, the compression spring 306 pushes the push rod 302 back to its original position under the action of elastic force. This cycle can continuously push the safety box 4 into the positioning hole 103.

[0039] In this embodiment, the bulk safety boxes 4 are first poured into the vibratory feeder 202, which outputs the safety boxes 4 in a uniform posture. At the connection between the first channel 201 and the second channel 203, the pusher plate 303 pushes the safety boxes 4 into the positioning hole 103 of the turntable 102. The turntable 102 drives the safety boxes 4 to rotate. Under the blocking action of the baffle 104, the buckle 401 undergoes elastic deformation after being blocked by the baffle 104, causing the barb between the box body and the lid to disengage, thereby achieving the effect of opening the lid of the safety box 4.

[0040] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
