Description

Technical Field

[0001] This invention relates to the field of electronic device manufacturing equipment technology, specifically to a device structure that automatically removes electrical connectors after they are seated. Background Technology

[0002] The use of electrical connectors in automobiles is becoming increasingly widespread, with a growing variety of structures. Furthermore, as the automotive industry continues to develop, the functions of these connectors are also expanding. Depending on the manufacturing quantity and usage, electrical connectors need to be installed in multiple locations within the vehicle. This situation necessitates increasingly higher manufacturing costs and assembly efficiency for these electrical components.

[0003] Because of the extremely high demand for the product, only semi-automatic and automated production can meet market needs. This ensures product consistency, interchangeability, and operability, thereby improving product quality and increasing work efficiency. The current connector mounting method requires the connector to be pre-installed into the housing and then pressed together. Therefore, this assembly process is inefficient and fails to meet standardization requirements. Furthermore, the production results do not meet expectations.

[0004] like Figure 1 As shown, the current methods for mounting the connectors are as follows:

[0005] The equipment mainly consists of the following components: (a) punch, (b) metal insert, (c) housing, and (d) base plate. The metal insert (b) is manually placed into the housing (c) individually, and then pressed into the base plate (d) using the punch (a). After assembly, the metal insert (b) is hung on the housing component to achieve its seated position. After pressing, tweezers are needed to help remove the metal insert (b) and housing (c) together. However, this method requires manual removal of the insert (b) with tweezers after pressing, which is slow, affects production efficiency, and cannot guarantee a high pass rate. It also easily causes jamming or bending of the metal insert (b), affecting subsequent assembly problems, hindering production efficiency, wasting semi-finished products, and increasing production costs. Furthermore, it is more prone to safety accidents caused by uncoordinated operation, resulting in personal injury and equipment damage. This structural method cannot meet the requirements of mass production and quality. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention aims to provide a device structure for automatically removing electrical connectors after they are seated. This solution saves time, improves production efficiency, and eliminates the unevenness, jamming, and tilting that can occur when manually removing connectors.

[0007] This invention is achieved through the following technical solution:

[0008] A device structure for automatically removing electrical connectors after they are seated includes:

[0009] A guide plate, along the length of the guide plate, has a plurality of pre-assembled products arranged sequentially on the guide plate, and a pushing mechanism is also provided on the guide plate, the pushing mechanism being used to push the pre-assembled products to the stamping limit position on the guide plate;

[0010] A sliding punch is disposed above the stamping limit position and is used to press the metal insert in the pre-assembled product into the housing in the pre-assembled product.

[0011] An unloading mechanism is provided on the side of the guide plate and is used to push the pre-assembled product that has been stamped out of the guide plate.

[0012] Compared to existing technologies, which negatively impact production efficiency and fail to guarantee a high pass rate, easily causing jamming or bending of metal connectors that hinders assembly and reduces production efficiency, this solution provides a device structure for automatic unloading of electrical connectors after they are seated. Specifically, the solution includes a guide plate with several pre-assembled products along its length. These pre-assembled products consist of pre-assembled metal connectors and housings. After pre-assembly, the pre-assembled products are placed on the guide plate. A pushing device then sequentially pushes these products to the stamping limit position, eliminating the need for manual placement. Compared to existing technologies, this solution eliminates the need for manual pushing of parts to the limit position, using a pushing mechanism to automatically move the parts, saving time, ensuring accuracy, reliability, and safety, and improving efficiency. It also ensures the verticality of the seated electrical connectors is unaffected by external forces, effectively reducing the scrap rate caused by manual factors and improving the accuracy after seating. Then, with the sliding punch positioned directly above the stamping limit, driving it downwards presses the metal insert into the housing, forming the product part. The sliding punch then slides upwards, and the unloading mechanism simultaneously ejects the product part to the unloading notch. The product part then simply falls from the unloading notch, completing the production of one part. The unloading mechanism automatically removes the product part during unloading, saving time compared to manual removal in existing technologies and eliminating the instability, jamming, and tilting issues associated with manual removal. This improves production efficiency and ensures operability, safety, and product consistency. The product qualification rate is also significantly improved.

[0013] Further optimization includes a fixed plate and a push rod. The fixed plate has a groove, and one end of the push rod is slidably connected to the groove via a slider and can slide along the length of the groove. The other end of the push rod is used to push the pre-assembled stamped product out of the guide plate. The fixed plate also has a drive mechanism for driving the push rod to slide, which is used to realize the ejection of the pre-assembled product.

[0014] In a further optimization, the fixed plate is also provided with a return spring. One end of the return spring is connected to the fixed plate near the push rod, and the other end of the return spring is connected to the push rod. The stretching direction of the return spring is set along the sliding direction of the push rod; it is used to realize the reciprocating motion of the push rod.

[0015] Further optimized, the drive mechanism includes a connecting rod, a one-way bracket, and a swing block. One end of the connecting rod is located above the fixed plate and hinged thereto, while the other end of the connecting rod abuts against one end of the push rod. The connecting rod can rotate within the plane of the fixed plate. The one-way bracket and the push rod are located on the same side of the connecting rod. One end of the one-way bracket is fixed to the connecting rod, and one end of the swing block is connected to the other end of the one-way bracket. The sliding punch has a stroke block, and the other end of the swing block is located within the stroke range of the stroke block's vertical movement. This design enables mechanical linkage and avoids the output of additional power.

[0016] Further optimization involves extending the other end of the connecting rod beyond the push rod, and ensuring that the sliding range of one end of the push rod is within the rotation range of the other end of the connecting rod. By extending the length of the connecting rod, it is possible to prevent one end of the push rod from detaching from the connecting rod during sliding.

[0017] Further optimization involves hinged connections between one end of the swing block and the other end of the unidirectional support to prevent the swing block from affecting the downward movement of the sliding punch.

[0018] In a further optimization, one end of the swing block is hinged to the other end of the one-way bracket via a torsion spring; this is used to achieve automatic reset of the swing block after it avoids an obstacle.

[0019] Further optimization involves adding a baffle at the upper end of the unidirectional support, which restricts the upward rotation of the other end of the pendulum block; by setting the baffle, the upward rotation of the pendulum block itself can be prevented.

[0020] Further optimization involves providing matching arc-shaped chamfered contact surfaces on the upper side of the other end of the swing block and the lower side of the end of the travel block. Through the contact of the arc-shaped surfaces, the swing block can be rotated downwards more stably, avoiding hard damage to the contact surfaces.

[0021] Further optimization involves using a cylinder as the pushing mechanism.

[0022] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0023] 1. This invention provides a device structure for automatically removing electrical connector plates after they are seated. Compared with existing technologies, it eliminates the need for manual pushing of the workpiece to the limit position. Instead, a cylinder automatically pushes the workpiece to the limit position, saving time, ensuring accuracy, reliability, and safety, and improving efficiency. It also ensures that the perpendicularity of the seated electrical connector is not affected by external forces, effectively reducing the scrap rate caused by manual factors. Furthermore, it improves the accuracy after seating.

[0024] 2. This invention provides a device structure for automatically removing electrical connectors after they are seated. A unique automatic unloading mechanism automatically removes the product during unloading, saving time compared to manual removal and eliminating the instability, jamming, and tilting issues associated with manual removal. This improves production efficiency and ensures operability, safety, and product consistency. The product qualification rate can also be significantly improved.

[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0035] Example

[0036] This embodiment provides a device structure for automatically removing electrical connectors after they are seated, such as... Figures 2 to 5 As shown, it includes:

[0037] Guide plate 3, along the length of guide plate 3, several pre-assembled products are sequentially arranged on guide plate 3, and push mechanism 7 is also provided on guide plate 3, which is used to push the pre-assembled products to the stamping limit position on guide plate 3.

[0038] Sliding punch 1 is positioned above the stamping limit position. Sliding punch 1 is used to press the metal insert 2 in the pre-assembled product into the housing in the pre-assembled product.

[0039] The unloading mechanism 6 is located on the side of the guide plate 3 and is used to push the pre-assembled product after stamping out of the guide plate 3.

[0040] Compared to existing technologies, which negatively impact production efficiency and fail to guarantee a high pass rate, and are prone to causing jamming or bending of the metal connector 2, hindering subsequent assembly and impeding production efficiency, this solution provides a device structure that automatically removes the electrical connector after it is seated. Specifically, in this solution, as shown... Figure 2The diagram shows the three views of the automatic unloading device structure: front view, side view, and top view. The structure includes a guide plate 3 with several pre-assembled products along its length. These pre-assembled products include pre-assembled metal inserts 2 and a housing. After pre-assembly, the pre-assembled products are placed onto the guide plate 3. A pushing device then sequentially pushes the pre-assembled products to the stamping limit position, eliminating the need for manual placement. Compared to existing technologies, this solution eliminates the need for manual pushing of the parts to be processed to the limit position. The pushing mechanism 7 automatically pushes the parts to the limit position, saving time, ensuring accuracy, reliability, and safety, and improving efficiency. It also ensures that the verticality of the seated electrical inserts is not affected by external forces, effectively reducing the scrap rate caused by manual factors and improving the accuracy after seating. Then, with the sliding punch 1 positioned directly above the stamping limit, driving it downwards presses the metal insert 2 into the housing, forming the product part. The sliding punch 1 then slides upwards, and the unloading mechanism 6 simultaneously ejects the product part to the unloading notch. The product part then simply falls from the unloading notch, completing the production of one part. The unloading mechanism 6 automatically removes the product part during unloading, saving time compared to manual removal in existing technologies and eliminating the instability, jamming, and tilting issues associated with manual removal. This improves production efficiency and ensures operability, safety, and product consistency. The product qualification rate is also significantly improved.

[0041] Please see Figure 3 As a specific implementation method for launching pre-assembled products, the unloading mechanism 6 is configured as follows: the unloading mechanism 6 includes a fixed plate 61 and a push rod 62. The fixed plate 61 has a groove. One end of the push rod 62 is slidably connected to the groove through a slider and can slide along the length of the groove. The other end of the push rod 62 is used to push the stamped pre-assembled product out of the guide plate 3. The fixed plate 61 also has a drive mechanism for driving the push rod 62 to slide.

[0042] It is understood that in this embodiment, a fixing plate 61 is provided on one side of the guide plate 3. The fixing plate 61 has a groove, which is long and narrow, so that the push rod 62 slides along the length of the groove. The sliding direction is perpendicular to the guide plate 3. The other end of the push rod 62 extends towards the guide plate 3 and points to the pre-assembled product at the limit position. Under the drive of the drive mechanism, the pre-assembled products that have been stamped are pushed out to the unloading outlet in sequence by the reciprocating sliding of the push rod 62 on the groove.

[0043] Please see Figure 3As a specific implementation method for realizing the reciprocating motion of the push rod 62, it is configured such that: a return spring 63 is also provided on the fixed plate 61, one end of the return spring 63 is connected to the fixed plate 61 near the push rod 62, the other end of the return spring 63 is connected to the push rod 62, and the stretching direction of the return spring 63 is set along the sliding direction of the push rod 62.

[0044] It is understood that in this embodiment, the two ends of the reset spring 63 are connected to the fixed plate 61 and the push rod 62 respectively. Under the drive of the driving device, the push rod 62 extends towards the guide plate 3. At this time, the compression spring is stretched. After the push-out work is completed, the spring can be reset under the elastic force of the compression spring.

[0045] Please see Figure 3 and Figure 5 As a specific implementation method for achieving mechanical linkage and avoiding the output of additional power, the drive mechanism is configured as follows: a connecting rod 64, a one-way bracket 65, and a swing block 66. One end of the connecting rod 64 is located above the fixed plate 61 and is hinged to it. The other end of the connecting rod 64 abuts against one end of the push rod 62. The connecting rod 64 can rotate within the plane of the fixed plate 61. The one-way bracket 65 and the push rod 62 are located on the same side of the connecting rod 64. One end of the one-way bracket 65 is fixed to the connecting rod 64, and one end of the swing block 66 is connected to the other end of the one-way bracket 65. The sliding punch 1 has a stroke block 11, and the other end of the swing block 66 is within the stroke range of the stroke block 11.

[0046] Understandably, in this embodiment, the stroke of the sliding punch 1 drives the drive mechanism to push the push rod 62 out. The drive mechanism specifically includes a connecting rod 64, a fixed bracket, and a swing block 66. One end of the connecting rod 64 is hinged to the fixed plate 61, and the other end extends downward and abuts against one end of the push rod 62. At this time, when the other end of the connecting rod 64 rotates around its own end, it drives the push rod 62 to slide. The one-way bracket 65 is fixedly connected to one end of the push rod 62 and is perpendicular to the push rod 62. The one-way bracket 65 is used to connect the swing block 66. During the upward movement of the sliding punch 1, since the end of the swing block 66 is within the upward stroke range of the sliding punch 1, it can drive the swing block 66 and the one-way bracket 65 to rotate upward. At this time, the connection rotates clockwise, thereby causing the other end of the connecting rod 64 to drive the push rod 62 to slide, and finally realize the ejection of the product part.

[0047] Please see Figure 3 As a specific implementation method to prevent the push rod 62 from disengaging from the connecting rod 64, in this embodiment, the other end of the connecting rod 64 extends beyond the push rod 62, and the sliding range of one end of the push rod 62 is within the rotation range of the other end of the connecting rod 64; by extending the length of the connecting rod 64, it is possible to prevent one end of the push rod 62 from disengaging from the connecting rod 64 during the sliding process.

[0048] Please see Figure 3 As a specific implementation method to avoid the swing block 66 affecting the downward movement of the sliding punch 1, in this embodiment, one end of the swing block 66 is hinged to the other end of the one-way bracket 65; so that one end of the swing block 66 is rotatably connected to the one-way bracket 65, and through the rotation of the swing block 66, it can avoid the downward movement of the sliding punch 1.

[0049] Please see Figure 3 As a specific implementation method for achieving automatic reset of the swing block 66 after avoidance, in this embodiment, one end of the swing block 66 is hinged to the other end of the one-way bracket 65 via a torsion spring 67. By setting the torsion spring 67, when the stroke block 11 moves downward, the swing block 66 is pushed to rotate counterclockwise, which will squeeze the torsion spring 67. When the stroke block 11 continues to move downward and disengages from the swing block 66, the swing block 66 is reset under the action of the torsion spring 67, so that the stroke block 11 can complete the pushing work when it moves upward.

[0050] As a redundancy solution, the upper end of the unidirectional support 65 is equipped with a baffle, which is used to restrict the other end of the swing block 66 from rotating upward. By setting the baffle, the swing block 66 can be prevented from rotating upward on its own. At this time, the swing block 66 rotates upward under the drive of the stroke block 11 moving upward. Under the obstruction of the baffle, it can only rotate upward synchronously with the unidirectional support 65, thereby completing the pushing work.

[0051] As a redundancy solution, the upper side of the other end of the swing block 66 and the lower side of the end of the stroke block 11 are both equipped with matching arc-shaped chamfered contact surfaces. Through the contact of the arc-shaped surfaces, the swing block 66 can be rotated downward more stably, avoiding hard damage to the contact surfaces. The arc-shaped chamfered contact surface of the swing block 66 is inclined downward towards the other end of the swing block 66, which can form a sliding guide for the stroke block 11 on its contact surface.

[0052] As a redundancy solution, the pushing mechanism 7 is a cylinder.

[0053] Working principle: Several pre-assembled products are sequentially placed along the length of the guide plate 3. Under the push of the cylinder, the pre-assembled products are moved sequentially to the stamping limit position. At this time, the sliding punch 1 is directly above the limit position. When the press press is in the downward stroke, it drives the sliding punch 1 to press down, thereby pressing the metal insert 2 into the housing. During the downward pressing process, it will drive the stroke block 11 to press down. When the stroke block 11 touches the swing block 66, the swing block 66 rotates and descends under the action of the pin. When it rotates to disengage from the stroke block 11, the swing block 66 springs back to its original position under the action of the torsion spring 67. At this point, the sliding punch 1 is still pressing down until it reaches the limit of the metal insert 2 and presses the metal insert 2 into the housing. At this time, the press starts to lift the upward stroke block 11 until the stroke block 11 touches the bottom of the swing block 66. The swing block 66 drives the connecting rod 64 to rotate through the one-way bracket 65 and pushes the push rod 62 forward, pushing down the finished metal insert 2 housing product. At this time, the stroke block 11 has disengaged from the swing block 66. Under the action of the return spring, the push rod 62 is pulled back to its original position, thus completing the production of a metal insert 2 housing product.

[0054] Through the above-described solution, this invention features low manufacturing cost, a reasonable and compact structure, simple and convenient manufacturing, high reliability, long lifespan, and wide applicability. It can meet the high-performance requirements of some existing metal insert mounting systems, has strong applicability, and offers significant advantages over existing technologies.

[0055] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
