[0001] The utility model relates to the technical field of pressure-maintaining equipment, in particular to a fool-proof device for a mechanical pressure-maintaining clamp. Background Art
[0002] Existing electronic devices such as mobile phones, tablet computers, and handheld communication devices require glue dispensing on the shell components of the electronic devices after the assembly process, and then pressure-holding and curing them through pressure-holding equipment. When using a mechanical pressure-holding clamp to hold the shell of the electronic device under pressure, the mechanical clamp may not be able to guarantee the stability and consistency of the pressure-holding clamping force due to factors such as improper operation, resulting in excessive pressure holding, and then causing batch maintenance after pressure holding, affecting production efficiency. Therefore, it is necessary to provide a mechanical pressure-holding clamp anti-fool device that can solve the problem in the prior art that the mechanical pressure-holding clamp cannot guarantee the consistency and stability of the pressure holding force. Summary of the invention
[0003] The utility model aims to provide a fool-proof device for a mechanical pressure-maintaining clamp, which can solve the problem in the prior art that the mechanical pressure-maintaining clamp cannot ensure the consistency and stability of the pressure-maintaining force.
[0004] The utility model is achieved in this way:
[0005] A mechanical pressure-maintaining fixture fool-proofing device comprises a differential head, a differential head block, a side push clamp, a product base and a tooling base; the product base is mounted on the tooling base, and the product is placed on the product base; a pair of side push clamps are slidably mounted on the tooling base, the pair of side push clamps are respectively located on both sides of the product base and slide relative to each other, a pair of pressure-maintaining profiling blocks are respectively detachably mounted on one side of the pair of side push clamps close to the product base, so that the pair of pressure-maintaining profiling blocks can be respectively pressed against both sides of the product through the pair of side push clamps; a pair of differential heads are respectively arranged on a pair of side push clamps, a pair of differential head blocks are respectively fixedly arranged on the tooling base, and the differential head block is located between the differential head and the product base, so that the differential head can collide with the differential head block.
[0006] The pair of side push clamps are respectively provided with digital dial gauges, and the ends of the digital dial gauges can contact the sides of the products.
[0007] When the pressure-holding profiling block is pressed against the side surface of the product with a specified pressure-holding force, the pointer of the digital micrometer is at zero position.
[0008] When the pointer of the digital display micrometer is at zero position, the end of the differential head abuts against the differential head stopper.
[0009] A pair of guide rail slider assemblies are provided on the tooling base, and the pair of guide rail slider assemblies are respectively located on both sides of the product base. A pair of side push clamps are respectively installed on the pair of guide rail slider assemblies, so that the side push clamps can slide closer to or away from the product through the guide rail slider assemblies.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] 1. Since the utility model is provided with a differential head and a differential head stopper, when the side push clamp drives the pressure-holding profiling block to move to press against the product with a specified holding pressure, the end of the differential head just rests against the differential head stopper. Therefore, in the subsequent batch pressure-holding operation, it is only necessary to push the pressure-holding profiling block along with the side push clamp until the end of the differential head rests against the differential head stopper. This can ensure the consistency and stability of the holding pressure of subsequent batch pressure-holding, play a fool-proof role, and is beneficial to improving the production efficiency and production quality of the product, and can be commonly used for pressure-holding operations of different electronic products.

When the side push clamp drives the pressure-holding contour block to move to press against the product with a specified pressure holding force, the digital dial gauge is at zero position. Therefore, in the subsequent batch pressure holding operation, it is only necessary to observe the reading of the digital dial gauge to quickly determine whether the pressure holding is excessive. The excessive pressure holding state is visualized, which is convenient for timely adjustment of the pressure holding operation and avoids the occurrence of batch maintenance.
[0013] 3. The utility model is provided with a guide rail slider assembly and a side push clamp, and the side push clamp moves linearly along the guide rail through the slider, thereby ensuring the controllability of the movement trajectory of the pressure-holding profiling block driven by the side push clamp, so as to improve the pressure-holding effect of the pressure-holding profiling block on the product.

[0016] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0017] Please see attached Figure 1, a mechanical pressure-maintaining fixture fool-proof device, comprising a differential head 2, a differential head block 3, a side push clamp 5, a product base 6 and a tooling base 7; the product base 6 is installed on the tooling base 7, and the product is placed on the product base 6; a pair of side push clamps 5 are slidably installed on the tooling base 7, a pair of side push clamps 5 are respectively located on both sides of the product base 6 and slide relatively, a pair of pressure-maintaining profiling blocks are respectively detachably installed on one side of the pair of side push clamps 5 close to the product base 6, so that a pair of pressure-maintaining profiling blocks can be pressed against both sides of the product through the pair of side push clamps 5; a pair of differential heads 2 are respectively arranged on a pair of side push clamps 5, a pair of differential head blocks 3 are respectively fixedly arranged on the tooling base 7, and the differential head block 3 is located between the differential head 2 and the product base 6, so that the differential head 2 can contact the differential head block 3.
[0018] Preferably, the side push clamp 5 can be a quick clamp of the Hercules clamp GH-31501-WDC push-pull clamp MC07-6 and other models, and the side push clamp 5 can be locked at a specified position by rotating the handle to ensure that the side push clamp 5 can be locked and positioned when the pressure-maintaining profiling block is pushed to press against the product with a specified holding pressure, so that the pressure-maintaining profiling block can press against the product tightly. The differential head 2 and the pressure-maintaining profiling block are detachably mounted on the side push clamp 5 and move synchronously with the side push clamp 5, which is convenient for disassembly and replacement, and the strokes of the three are kept consistent.
[0019] When the pressure-holding profiling block presses the product with a specified holding pressure, that is, when the sliding stroke of the pressure-holding profiling block is determined by the side push clamp 5, the differential head 2 can be pressed against the differential head stopper 3. Therefore, in the subsequent pressure-holding operation, it is only necessary to push the pressure-holding profiling block until the differential head 2 presses against the differential head stopper 3, so as to ensure the consistency and stability of the pressure of the pressure-holding profiling block on the product, ensure that the pressure-holding operation of the product has good controllability and easy operability, achieve the purpose of fool-proofing, and is conducive to improving the production efficiency and production quality of the product.
[0020] At the same time, the adjustment accuracy of the differential head 2 can reach more than 0.005mm, which can accurately control the movement stroke of the pressure-holding profiling block, thereby further ensuring the control accuracy of the pressure-holding pressure.
[0021] Preferably, the tooling base 7 can adopt a flat plate base, and the product base 6 can be selected according to the shape and size of the product. The product base 6 can be installed on the tooling base 7 by screwing or the like, which is convenient for replacing the product base 6 according to the product model.
[0022] Preferably, the micrometer head 2, the micrometer head block 3, and the side push clamp 5 are arranged in groups, and their number and position can be adaptively installed according to the pressure points of the pressure-maintaining operation, so that each pressure point can perform independent pressure-maintaining and fool-proofing.
[0023] The pair of side push clamps 5 are respectively provided with a digital dial gauge 1, and the end of the digital dial gauge 1 can contact the side of the product.
[0024] When the product is over-pressurized, that is, the actual sliding stroke of the pressure-holding profiling block exceeds the preset stroke, the product is over-pressurized, and the differential head 2 will also over-exert the differential head block 3. In order to visualize the over-pressurization state, a digital dial gauge 1 is installed on the side push clamp 5. The digital dial gauge 1 slides synchronously with the side push clamp 5. The end of the digital dial gauge 1 will produce a corresponding reading when it is subjected to the extrusion force, so that the over-pressurization state of the product can be visualized by using the reading of the digital dial gauge 1, thereby improving the fool-proof effect of the product pressure-holding operation.
[0025] When the pressure-holding profiling block is pressed against the side of the product with a specified pressure-holding force, the pointer of the digital micrometer 1 is at zero position.
[0026] When the pressure-holding profiling block is at the specified holding pressure, the pointer of the digital dial gauge 1 can be reset to zero to indicate the normal holding pressure state. When the end of the digital dial gauge 1 is subjected to the extrusion force, the pointer of the digital dial gauge 1 rotates to indicate the over-holding pressure state, thereby realizing the visualization of the over-holding pressure state. At the same time, the degree of over-holding pressure can also be indicated by the reading size of the pointer rotation.
[0027] When the pointer of the digital micrometer 1 is at zero position, the end of the differential head 2 just abuts against the differential head stopper 3.
[0028] When the pointer of the digital micrometer 1 is at zero position, that is, under normal pressure holding state, adjust the end of the differential head 2 to just abut against the differential head stopper 3, so that in the subsequent batch pressure holding operation, it is only necessary to slide the side push clamp 5 until the differential head 2 abuts against the differential head stopper 3 to ensure that the pressure holding profiling block maintains normal pressure on the product, thereby ensuring the consistency of the pressure holding operation.
[0029] A pair of guide rail slider assemblies 4 are provided on the tooling base 7, and the pair of guide rail slider assemblies 4 are respectively located on both sides of the product base 6, and a pair of side push clamps 5 are respectively installed on the pair of guide rail slider assemblies 4, so that the side push clamps 5 can slide close to or away from the product through the guide rail slider assemblies 4.
[0030] Preferably, each set of guide rail and slider assemblies 4 may include guide rails and sliders, the guide rails are mounted on a tooling base 7 beside the product base 6, the bottom of the slider is slidably embedded in the guide rails, and the top of the slider is connected to the bottom of the side push clamp 5, so that the side push clamp 5 can move linearly along the guide rails, ensuring the controllability of the motion trajectory of the pressure-holding profiling block and providing uniform and stable pressure holding for the product.
[0031] Please see attached Figure 1 , the usage method and working principle of the utility model are:
[0032] Place the product that needs to be pressure-maintained and cured after dispensing on the product base 6, select the corresponding pressure-maintaining profiling block according to the product pressure-maintaining requirements, and install a pair of pressure-maintaining profiling blocks on a pair of side push clamps 5 respectively.
[0033] Preferably, a rectangular mounting plate 501 can be provided at the end of the side push clamp 5, so that the differential head 2 and the digital micrometer 1 can be installed to the two ends of the mounting plate 501 of the side push clamp 5 through the L-shaped bracket 502, the pressure-maintaining profiling block is installed to one side of the mounting plate 501 of the side push clamp 5, and the slider of the guide rail slider assembly 4 is installed to the bottom of the mounting plate 501 of the side push clamp 5.
[0034] The side push clamp 5 is pushed toward the product base 6 through the guide rail slider assembly 4, and the pressure-holding profiling block is pressed against the side of the product with a specified holding pressure so that it can meet the pressure-holding requirements. The specified holding pressure of the pressure-holding profiling block can be accurately measured according to the pressure-holding requirements in combination with test pieces such as pressure sensors in the prior art. It does not belong to the protection scope of the present utility model, and the pressure-holding measurement process will not be repeated here.
[0035] After the pressure-holding profiling block reaches the specified holding pressure, return the digital dial gauge 1 to zero, that is, adjust the pointer of the digital dial gauge 1 to the 0 scale, and the end of the digital dial gauge 1 just contacts the zero pressure on the side of the product. At the same time, adjust the differential head 2 so that the end of the differential head 2 just rests on the differential head stopper 3, and lock the end of the differential head 2 at this position.
[0036] After the adjustment is completed, when the side push clamp 5 is at this position, the pressure-maintaining profiling block can maintain the pressure of the product at a specified pressure. Each side push clamp 5 is adjusted in the same way, and will not be described one by one here.
[0037] When batch pressure is maintained for products, the products are placed directly on the product base 6, and a pair of side push clamps 5 slide toward the products through the guide rail slider assembly 4 until the end of the differential head 2 rests on the differential head stop block 3. The pair of side push clamps 5 are locked to realize a pair of pressure-maintaining profiling blocks to clamp the products with a specified holding pressure.
[0038] At this time, the end of the digital micrometer 1 just touches the side of the product but there is no pressure, and the pointer remains at the 0 scale. If excessive pressure holding occurs, that is, the stroke of the pressure holding profiling block exceeds the preset range with the side push clamp 5, the stroke of the digital micrometer 1 also increases, and an extrusion force is generated between the product and the end of the digital micrometer 1, causing the digital micrometer 1 to produce a reading.
[0039] Therefore, in the subsequent batch pressure holding operation, it is only necessary to move the pressure holding profiling block until the end of the micrometer head 2 contacts the micrometer head stopper 3 to ensure the consistency of the pressure holding and achieve the purpose of foolproofing. The reading change of the digital micrometer 1 can be used to observe whether the product has excessive pressure holding, and the degree of excessive pressure holding can also be judged according to the reading, so as to timely adjust the pressure holding pressure, that is, the sliding stroke of the pressure holding profiling block through the side push clamp 5.
[0040] For the pressure-maintaining operation of existing electronic devices such as mobile phones, tablet computers, and handheld communication devices, it is only necessary to replace the product base 6 of the corresponding size and the corresponding pressure-maintaining profiling block, which has good versatility.
[0041] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
