Description

Technical Field

[0001] This application relates to the field of assembling 3C product casings, and more particularly to an assembly fixture for assembling a back cover with a bayonet and a workstation having the same. Background Technology

[0002] With the continuous promotion of electronic products, 3C products are closely related to people's lives. For example, 3C products include computer, communication and consumer electronics products. People's demand for these products is increasing year by year. With the improvement of 3C product production capacity, based on different functional modules, they are generally assembled by shell to form a collection of one, two or more functional modules.

[0003] In the assembly process of 3C product casings, the current assembly method is manual assembly, which does not rely on special jigs involved in assembly actions. Instead, some auxiliary tools are used, such as: making a work plate, fixing the base plate on the work plate, and manually holding a pressure bar to press down on the product to be assembled from one point to the next. Since metal products have a certain toughness and are not easily deformed, manual application of the pressure bar to press down on multiple points within a safe force range will not damage the metal products.

[0004] However, the following problems may exist: First, the manual assembly process involves constant contact with the product, which can easily cause the product to become dirty; second, if excessive force is applied during manual pressing, the product may be directly damaged; third, it is easy for structural or functional components to be missing, which is troublesome to disassemble and repair, and may even lead to the product being scrapped. Utility Model Content

[0005] This application provides an assembly fixture and a workstation having the same, to solve the technical problem in the prior art that manual assembly can easily cause dirt, damage or scrap to the product.

[0006] The assembly fixture provided by this utility model includes: a platform, limiting blocks, and a pressing assembly. The platform has a bearing groove for bearing the workpiece to be assembled. The platform also has a pre-positioning mounting position, an alignment mounting position, and a positioning mounting position. The pre-positioning mounting position is used to extend into a first position area of ​​the workpiece to be assembled and pre-position it. The alignment mounting position is used to initially position at least a portion of the structure of the workpiece to be assembled to a second position area of ​​the platform. The positioning mounting position is used to limit the workpiece to be assembled along a first direction to a third position area of ​​the platform. The limiting blocks are arranged in pairs, and the platform reciprocates between the two limiting blocks along the first direction. The pressing assembly is located above the platform and the limiting blocks and can press down toward the workpiece to be assembled, forming a pressing force on the surface of the workpiece.

[0007] The assembly fixture further includes a pre-positioning component, which is detachably mounted on the pre-positioning mounting position. The pre-positioning component includes at least one first slider. The platform has a first sliding groove. The first slider is slidably connected to the first sliding groove along a second direction. The first slider has a support foot protruding from the plane of the platform. The support foot is used to extend into a first position area of ​​the part to be assembled and abut against the side wall of the first position area, so that the pre-positioning mounting position restricts the part to be assembled from dislodging from the bearing groove along the first direction.

[0008] The assembly fixture further includes an alignment component, which is detachably installed in the second position area of ​​the platform. The alignment component includes a cover plate, a first positioning pin, a second positioning pin, and a connecting rod.

At least part of the outer diameter of the connecting rod is clamped in a limiting hole below the cover plate. The first positioning pin and the second positioning pin can be elastically connected to the platform along a third direction and can be embedded in or protrude from the surface of the platform during elastic movement.

[0009] The assembly fixture further includes a positioning component, which is detachably installed in the third position area of ​​the platform. The positioning component includes a second slider, two pressure blocks, and two magnetic fixing blocks. The two magnetic fixing blocks are respectively disposed on the front and rear sides of the second slider along the first direction. The two pressure blocks respectively clamp the limiting grooves disposed on both sides of the second slider along the second direction. The second slider and each of the magnetic fixing blocks are configured with opposite magnetic poles so that the second slider can attract the two magnetic fixing blocks respectively.

[0010] The assembly fixture further includes a first driving component, which is mounted on the platform. The first driving component is used to reduce the pre-assembly space of the bearing groove along the first direction so that the part to be assembled is pre-positioned between the bearing groove and the positioning component.

[0011] The first drive assembly includes a first power component and a first push plate. The first push plate is connected to the kinetic energy output end of the first power component. The first power component is capable of reciprocating the first push plate along the first direction. A gap is left between the tail end of the first push plate and the edge of the component to be assembled.

[0012] The assembly fixture further includes a second drive assembly mounted on one side of the platform. The second drive assembly is used to press down toward the workpiece to be assembled along the third direction and can be guided and aligned with at least a portion of the structure of the platform so that the second drive assembly provides a force parallel to its own assembly plane to the workpiece to be assembled.

[0013] The second driving component includes a second power component, a second push plate, a positioning pin, and a first guide post. The second push plate is connected to the kinetic energy output end of the second power component. The positioning pin and the first guide post extend below the second push plate. During the process of the second power component pushing the second push plate downward, the positioning pin is aligned with the guide hole on the alignment component, and the first guide post is aligned with the preset guide hole on the platform.

[0014] The second drive assembly further includes a roller assembly, which is mounted on the lower surface of the second push plate. Multiple roller assemblies are provided, and each roller assembly is pressed onto a preset mounting position of the component to be assembled by rollers.

[0015] The roller assembly includes a pair of roller supports and a rubber roller that is rolled between the two roller supports. Each roller support is assembled with the rubber roller by a connecting post and a retaining spring.

[0016] The assembly fixture further includes a prepositioning component, which is mounted on a workbench. A support block is mounted on the prepositioning component, and the second power unit is fixedly mounted on the support block. A connecting plate is provided below the support block, and the connecting plate is connected to the surface of the workbench through a second guide post passing through the second push plate.

[0017] The workstation provided by this utility model includes the above-mentioned assembly fixture. The workstation includes: an assembly fixture for supporting a touch panel with a pre-installed balance bar and an iron sheet pre-assembled above the touch panel; and a worktable. The worktable has a preset slide rail structure. The bottom surface of the platform in the assembly fixture has a slider structure. The slider structure is slidably assembled with the slide rail structure so that the platform can reciprocate between the limiting block and the worktable along the first direction.

[0018] The technical solutions provided in this application have the following advantages compared with the prior art:

[0019] The assembly fixture and workstation provided in this application embodiment pre-install a touch panel with a pre-assembled balance bar in the bearing groove of the platform. The platform is then moved to the working area between two limiting blocks. At this time, the side of the touch panel away from the balance bar is positioned near the positioning mounting position, and the side of the touch panel with the balance bar is positioned near the pre-positioning mounting position. The pre-positioning mounting position extends into the first position area of ​​the part to be assembled and is pre-positioned. Moving the positioning mounting position causes one side of the touch panel to abut against the inner edge of the bearing groove, and the other side of the touch panel to abut against at least a portion of the structure of the positioning mounting position; that is, positioning... The mounting position can confine the component to be assembled in the third position area of ​​the platform along the first direction. Then, the iron plate with the hanging lugs is placed on the top surface of the touch panel and covers the balance bar. At this time, the structure of the hanging lugs can be aligned with the mounting position on the platform to prevent the iron plate from moving circumferentially relative to the touch panel. The pressing assembly is activated, pressing it down towards the iron plate and the touch panel with the balance bar, forming a uniform pressing force on the surface of the iron plate. In this way, under the action of the pressing assembly, combined with the alignment and locking structure between the iron plate and the touch panel, the iron plate can be assembled with the touch panel into a single structure. Using the assembly fixture of this utility model to align and lock the iron plate and the touch panel for assembly, compared with manual operation, can speed up the assembly efficiency, reduce the contact between the hands and the components to be assembled, improve the cleanliness of the components to be assembled in the assembly process, and also avoid the problem of missing components to be assembled.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0037] For ease of description, spatial relative terms may be used in this text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptions used in this text have been explained accordingly.

[0038] Taking a laptop computer as an example of a 3C product, the assembly fixture of this application can align and assemble shells or accessories that require snap-fit ​​installation. For example, taking a touch module as an example of a shell that requires snap-fit ​​installation, generally speaking, a touch module includes a touchpad and a metal sheet. This application takes the part to be assembled as a touchpad and / or a metal sheet as an example to further illustrate the specific structure of the assembly fixture.

[0039] refer to Figures 1-10The assembly fixture and workstation provided in this application can solve the technical problem that manual assembly in the prior art can easily cause dirt, damage or scrap to the product. For ease of description, the first direction is defined as the moving direction of the platform 1, that is, the length direction of the platform 1; the second direction is defined as the extension direction of the support leg 521 in the prepositioning component 5, that is, the width direction of the platform 1; and the third direction is defined as the elastic moving direction of the first positioning pin 63 and the second positioning pin 65, that is, the thickness direction of the platform 1.

[0040] Specifically, the assembly fixture provided by this utility model includes: a platform 1, limiting blocks 2, and a pressing component 7. The platform 1 has a bearing groove 11, which is used to support the parts to be assembled. For example, this application does not limit the specific shape and size of the bearing groove 11, but generally adapts to the outline shape of the parts to be assembled. The platform 1 has a pre-positioning mounting position 1a, an alignment mounting position 1b, and a positioning mounting position 1c. The pre-positioning mounting position 1a is used to extend into the first position area of ​​the parts to be assembled and pre-position them. The alignment mounting position 1b is used to initially position at least a part of the structure of the parts to be assembled to the second position area of ​​the platform 1. The positioning mounting position 1c is used to limit the parts to be assembled to the third position area of ​​the platform 1 along the first direction. The limiting blocks 2 are arranged in pairs, and the platform 1 moves back and forth between the two limiting blocks 2 along the first direction. For example, a handle 12 is provided on one side of the platform 1. Pulling the handle 12 can move the platform 1 relative to the two limiting blocks 2. The pressing component 7 is located above the stage 1 and the limiting block 2, and can press down toward the part to be assembled and form a pressing force on the surface of the part to be assembled.

[0041] This application does not limit the specific locations of the first position area, the second position area, and the third position area, as long as the three position areas are set in different positions. Furthermore, the three position areas, combined with the corresponding pre-positioned mounting position 1a, aligned mounting position 1b, and positioning mounting position 1c, can align and assemble the pre-installed touch panel with a sense of balance and the iron sheet into a stable structure.

[0042] Using the assembly fixture of this application, a touch panel pre-assembled with a balance bar is pre-installed in the bearing groove 11 of the platform 1. The platform 1 is then moved to the working area between the two limiting blocks 2. At this time, the side of the touch panel away from the balance bar is positioned near the positioning mounting position 1c, and the side of the touch panel with the balance bar is positioned near the pre-positioning mounting position 1a. The pre-positioning mounting position 1a extends into the first position area of ​​the part to be assembled and is pre-positioned. When the positioning mounting position 1c is moved, one side of the touch panel abuts against the inner edge of the bearing groove 11, and the other side of the touch panel abuts against at least a portion of the structure of the positioning mounting position 1c, that is, the positioning mounting position is completed. Position 1c can confine the component to be assembled in the third position area of ​​the platform 1 along the first direction. Then, the iron sheet with the hanging lugs is placed on the top surface of the touch panel and covers the balance bar. At this time, the structure of the hanging lugs can be aligned with the alignment mounting position 1b of the platform 1 so that the iron sheet will not move in the circumferential direction relative to the touch panel. The pressing component 7 is activated and pressed down towards the iron sheet and the touch panel with the balance bar, forming a uniform pressing force on the surface of the iron sheet. In this way, under the action of the pressing component 7, combined with the alignment and locking structure between the iron sheet and the touch panel, the iron sheet can be assembled with the touch panel into a whole structure. Using the assembly fixture of this utility model to align and lock the iron sheet and the touch panel can speed up the assembly efficiency compared with manual operation, reduce the contact between the hands and the components to be assembled, improve the cleanliness of the components to be assembled in the assembly process, and avoid the problem of missing components to be assembled.

[0043] Considering the initial positioning scheme of the pre-positioning mounting position 1a relative to the part to be assembled and the specific scheme for initial positioning corresponding to the bearing groove 11, the assembly fixture of this application also includes a pre-positioning component 5. The pre-positioning component 5 is detachably installed at the pre-positioning mounting position 1a. Here, detachable installation can be understood as the pre-positioning component 5 being assembled and disassembled relative to the pre-positioning mounting position 1a of the platform 1 as needed. During operation, it can ensure the stable installation of the pre-positioning component 5 at the pre-positioning mounting position 1a of the platform 1. Specifically, the pre-positioning component 5 includes at least one first slider 52. The platform 1 has a first sliding groove. The first slider 52 is slidably connected to the first sliding groove along the second direction. The first slider 52 has a support foot 521 protruding from the plane of the platform 1. The support foot 521 is used to extend into the first position area of ​​the part to be assembled and abut against the side wall of the first position area, so that the pre-positioning component 5 restricts the part to be assembled from coming out of the bearing groove 11 along the first direction. That is, the part to be assembled will not come out of the bearing groove 11 along the first direction. For example, the pre-positioning component 5 of this application can be a sensor 51 component, depending on the needs of the actual application scenario. For example, the sensor 51 component can include an infrared transmitter and an infrared receiver, wherein the infrared transmitter transmits a start signal to the infrared receiver, and the infrared receiver extends a support foot 521 to abut against the side wall of the first position area on the touch panel. It should be noted that the first position area on the touch panel has a pre-set side wall, and the pre-positioning component 5 of this application is a pre-positioning scheme structure corresponding to the side wall.

[0044] In this way, by using the prepositioning component 5, the touch panel can be limited at its structural position on its own side wall, so that the touch panel will not move in the first direction between the side wall and one side of the bearing groove 11 of the platform 1.

[0045] Considering the assembly includes a touchpad pre-installed with a balance bar and an iron plate assembled from above the touchpad and fastened to it, with the iron plate having a hanging ear positioned on its side wall along a second direction, based on this structure, the assembly fixture of this application is provided with an alignment component 6. At least a portion of the structure of the alignment component 6 can extend into the hanging ear, and the alignment component 6 can limit the iron plate in the circumferential direction at the hanging ear position, preventing the iron plate from moving in the circumferential direction at the hanging ear position. Furthermore, this application has two hanging ears, respectively disposed on both sides of the iron plate along the second direction, that is, this application includes two alignment components 6, each alignment component 6 corresponding to limit one hanging ear.

[0046] Specifically, the assembly fixture of this application also includes an alignment component 6, which is detachably installed in the second position area of ​​the platform 1. The alignment component 6 includes a cover plate 61, a first positioning pin 63, a second positioning pin 65, and a connecting rod 66. The first positioning pin 63 and the second positioning pin 65 are vertically arranged along a third direction. The first positioning pin 63 and the second positioning pin 65 are sleeved on both ends of the connecting rod 66 along a third direction. At least part of the outer diameter of the connecting rod 66 is clamped in the limiting hole 671 below the cover plate 61. The first positioning pin 63 and the second positioning pin 65 can be elastically connected to the platform 1 along a third direction and can be embedded in or protrude from the surface of the platform 1 during elastic movement. For example, the cover plate 61 is provided with a first through hole 62 for the first positioning pin 63 or the second positioning pin 65 to pass through.

[0047] Thus, based on the variation in the size of the lugs on the iron sheet, one of the first positioning pin 63 and the second positioning pin 65 of this application can be inserted into the through hole of one side of the lug, while the other will spring back downward during the downward pressing process of the pressing assembly 7. Specifically, a limiting plate 67 is provided below the cover plate 61, and a limiting hole 671 is provided on the limiting plate 67. At least a portion of the connecting rod 66 protrudes from the limiting hole 671, and at least a portion of the connecting rod 66 is clamped to the inner wall of the limiting hole 671. By adopting such a structure of the alignment assembly 6, different types of iron sheets can be matched, thereby adapting to the assembly of different types of touch modules.

[0048] Considering that the side of the touchpad with the pre-installed balance bar may move relative to the bearing groove 11, the assembly fixture provided in this application is also provided with a positioning component 4. The positioning component 4 can directly limit the side wall of the touchpad with the pre-installed balance bar, thereby making the touchpad stably limited in the bearing groove 11 along the first direction.

[0049] Specifically, the assembly fixture of this application also includes a positioning component 4, which is detachably installed in the third position area of ​​the platform 1. This detachable installation means that the components of the positioning component 4 can be assembled and disassembled relative to the third position area of ​​the platform 1 according to actual needs. The positioning component 4 includes a second slider 41, two pressure blocks 42, and two magnetic fixing blocks. The two magnetic fixing blocks are respectively disposed on the front and rear sides of the second slider 41 along the first direction. The two pressure blocks 42 respectively clamp the limiting grooves disposed on both sides of the second slider 41 along the second direction. The second slider 41 and each magnetic fixing block are configured with opposite magnetic poles so that the second slider 41 can attract the two magnetic fixing blocks respectively.

[0050] In this way, by moving the second slider 41 toward the touchpad, the second slider 41 can magnetically attract the front magnetic fixing block, so that the second slider 41 moves to the front magnetic fixing block, i.e., the first magnetic fixing block 43. At this time, the front wall of the first magnetic fixing block 43 can abut against the side wall of the touchpad. By moving the second slider 41 away from the touchpad, the second slider 41 can magnetically attract the rear magnetic fixing block, so that the second slider 41 moves to the rear magnetic fixing block, i.e., the second magnetic fixing block 44. At this time, the second magnetic fixing block 44 is released from the limit of the side wall of the touchpad. After the alignment and assembly of the touchpad and the iron sheet is completed, the assembled assembly can be quickly removed, and a new part to be assembled can be quickly placed in.

[0051] Considering that the bearing groove 11 has a structure that is closed on one side and open on the other, after the touch panel is placed in the bearing groove 11, it is easy for it to slip from the open area of ​​the bearing groove 11. In order to avoid this slippage problem, the assembly fixture of this application uses the first driving component 3 to fill the open area of ​​the bearing groove 11 and block the touch panel at that position.

[0052] Specifically, the assembly fixture also includes a first driving component 3, which is mounted on the stage 1. The first driving component 3 is used to reduce the pre-assembly space of the bearing groove 11 along a first direction, so that the part to be assembled is pre-positioned between the bearing groove 11 and the positioning component 4. In this way, at least a portion of the structure of the first driving component 3 and the bearing groove 11 together form a relatively closed pre-assembly space for accommodating the touch panel, which can prevent the touch panel from sliding out along the opening area of ​​the bearing groove 11.

[0053] Considering the specific blocking scheme of the first driving component 3 on the touchpad, the first driving component 3 of this application includes a first power component 31 and a first push plate. The first push plate is connected to the kinetic energy output end of the first power component 31. The first power component 31 can reciprocate the first push plate along a first direction, and a gap is left between the tail end of the first push plate and the edge of the part to be assembled. For example, the first power component 31 can be a quick clamp structure, a cylinder structure, or an electric steel structure. The first power component 31 can be set to manual drive or automatic drive, depending on the requirements of the actual application scenario. It should be noted that the gap between the first push plate and the edge of the part to be assembled can be set according to the requirements of the actual application scenario. The gap can be 0 or a value greater than 0, and this application does not limit it in this regard.

[0054] Considering the power source for the pressing component 7 to move toward the workpiece to be assembled, the assembly fixture of this application also includes a second drive component 8. The second drive component 8 is mounted on one side of the stage 1. The second drive component 8 is used to drive the pressing component 7 to press down toward the workpiece to be assembled in a third direction, and can guide and align the pressing component 7 with at least a part of the structure of the stage 1, so that the second drive component 8 provides a force parallel to its own assembly plane to the workpiece to be assembled through the pressing component 7.

[0055] Considering the structural arrangement of the second drive assembly 8, the pressing assembly 7, the parts to be assembled, and the corresponding positions on the platform 1, in the assembly fixture of this application, the second drive assembly 8 includes a second power component, the pressing assembly 7 includes a second push plate, a positioning pin 72, and a first guide post 73. The second push plate is connected to the kinetic energy output end of the second power component. The positioning pin 72 and the first guide post 73 extend below the second push plate. During the process of the second power component pushing the second push plate downward, the positioning pin 72 is guided and aligned with the guide hole 64 on the alignment assembly 6, and the first guide post 73 is guided and aligned with the preset guide hole 64 on the platform 1. For example, the guide hole 64 can be formed by the platform 1, or it can be formed by the cover plate 61 and the connecting plate 15 of the alignment assembly 6. This application does not limit the formation position of the guide hole 64.

[0056] For example, the second power component can be a quick clamp structure, a cylinder structure, or an electric steel structure. The second power component can be set to manual drive or automatic drive, depending on the requirements of the actual application scenario.

[0057] In this way, the second power component can push the pressing assembly 7 to move downward. After the positioning pin 72 is guided and aligned with the guide hole 64 on the alignment assembly 6, the second push plate can move downward along the first guide post 73 to avoid deviation from the touch panel during the downward movement of the second push plate.

[0058] Considering that after the pressing component 7 moves toward the touch panel, at least a portion of the structure of the pressing component 7 can match the groove structure of the preset mounting position on the touch panel, that is, a fixed-point limiting is formed between the pressing component 7 and the touch panel. Specifically, the second driving component 8 of this application also includes a roller assembly 71, which is mounted on the lower surface of the second push plate. Multiple roller assemblies 71 are provided, and each roller assembly 71 is pressed onto the preset mounting position of the component to be assembled by rollers. For example, the preset mounting position of the component to be assembled can be a through hole structure.

[0059] Considering the specific structural composition of the roller assembly 71, the roller assembly 71 of this application includes a pair of roller supports 712 and a rubber roller 711 that is rolled and clamped between the two roller supports 712. Each roller support 712 is assembled with the rubber roller 711 by a connecting post 713 and a retaining spring. This application does not limit the specific structure, shape, or size of the roller support 712 and the connecting post 713, as long as the connecting post 713 can pass through one roller support 712, the rubber roller 711, and the other roller support 712 in sequence, and the two ends of the connecting post 713 are respectively positioned on the two roller supports 712 by the retaining spring.

[0060] Considering the fixing scheme of the second drive component 8, the assembly fixture of this application also includes a fixing component 10. The fixing component 10 is installed on a workbench, and a support block 9 is installed on the fixing component 10. The second power unit is fixedly installed on the support block 9. A connecting plate 15 is provided below the support block 9. The connecting plate 15 is connected to the surface of the workbench through a second guide post 14 passing through the second push plate. With the second guide post 14, the second push plate can avoid displacement of the component to be assembled during the downward movement of the second push plate. For example, the fixing component 10 of this application can be assembled from various plates. For example, the fixing component 10 can include an overall frame structure that provides support by assembling a vertical plate, a support plate, an auxiliary plate, and a base plate. In this way, the second drive component 8 can be stably set above the platform 1 by the fixing component 10, and the second drive component 8 can be set to move towards the platform 1 according to the requirements of the alignment process.

[0061] In summary, using the assembly fixture of this application, the second drive assembly 8 controls the stroke of the pressing assembly 7 and locks it in place, while the first drive assembly 3 controls the stroke of the component moving towards the touchpad, thus enabling the product to be pushed and allowing for the quick insertion or removal of the protective block. The handle 12 pulls the platform 1 (i.e., the carrier plate) relative to the limiting block 2 and the worktable 20, allowing the platform to be pulled out, the product assembled, the carrier plate pushed forward, and subsequent operations completed. The roller assembly 71, when the second drive assembly 8 is pressed down and locked, applies downward pressure to the product, ensuring the slots on the iron sheet reach the pushable height. Simultaneously, when pushing the product, the rotation of the rubber roller 711 reduces friction, allowing the pushing force in the first direction to complete the assembly process. The positioning assembly 4, with the pressure block 42 inserted into the second slider 41, prevents the second slider 41 from moving in the third direction. The second slider 41 moves forward, attracting the first magnetic fixing block 43 in front, and backward, attracting the second magnetic fixing block 44 behind, thus achieving a stabilizing effect. The first slider 52 is pushed to the middle position between the product's cover and the base plate, causing the assembled shell to tilt upwards and preventing wear or damage to parts during the pushing process. Using the pre-positioning component 5, the first slider 52 can be positioned at a preset position on the product and abut against the side wall of that preset position. Using the alignment component 6, positioning is required when the product's cover is placed into the base plate to determine the accurate position. However, the pins may affect movement in the first direction, preventing the cover 61 from moving in that direction. This structure, however, will press down in the middle, causing the positioning pin 72 to press down on the spring under the pressure. The positioning pin 72 is then embedded below, thus providing positioning before the rubber roller 711 descends, preventing interference from the positioning pin 72 during the pushing process. The structure of the first guide post 73 and the second guide post 14 allows the second push plate to be accurately pressed into the position requiring assembly pressure.

[0062] Considering the practical application scenarios of the assembly fixture, this application also provides a workstation, including the aforementioned assembly fixture. The workstation includes: an assembly fixture for supporting a touchpad with a pre-installed balance bar and an iron plate pre-assembled above the touchpad; and a worktable 20. The worktable 20 has a pre-set slide rail structure 13. The bottom surface of the platform 1 in the assembly fixture has a slider structure, which is slidably assembled with the slide rail structure 13, so that the platform 1 can reciprocate between the limiting block 2 and the worktable 20 in a first direction. For example, the worktable 20 may also have a pre-set slider structure, and the bottom surface of the platform 1 in the assembly fixture may also have a slide rail structure 13, whereby the slider structure and the slide rail structure 13 can still be slidably assembled.

[0063] The workstation described in this application can achieve all the effects of the assembly fixtures mentioned above, which will not be elaborated here.
